ARTICLE 10: PRESERVATION OF HISTORICAL ARCHITECTURAL AND AESTHETIC LANDMARKS

Editor's Note:

See also Article 11, "Preservation of Buildings and Districts of Architectural, Historical, and Aesthetic Importance in the C-3 Districts."

It is hereby found that structures, sites and areas of special character or special historical, architectural or aesthetic interest or value have been and continue to be unnecessarily destroyed or impaired, despite the feasibility of preserving them. It is further found that the prevention of such needless destruction and impairment is essential to the health, safety and general welfare of the public. The purpose of this legislation is to promote the health, safety and general welfare of the public through:

(a) The protection, enhancement, perpetuation and use of structures, sites and areas that are reminders of past eras, events and persons important in local, State or national history, or which provide significant examples of architectural styles of the past or are landmarks in the history of architecture, or which are unique and irreplaceable assets to the City and its neighborhoods, or which provide for this and future generations examples of the physical surroundings in which past generations lived;

(b) The development and maintenance of appropriate settings and environment for such structures, and in such sites and areas;

(c) The enhancement of property values, the stabilization of neighborhoods and areas of the City, the increase of economic and financial benefits to the City and its inhabitants, and the promotion of tourist trade and interest;

(d) The preservation and encouragement of a City of varied architectural styles, reflecting the distinct phases of its history: cultural, social, economic, political and architectural and

(e) The enrichment of human life in its educational and cultural dimensions in order to serve spiritual as well as material needs, by fostering knowledge of the living heritage of the past.

(2) Fenestration and Design Elements for New Construction. In areas with a concentration of older brick buildings, new construction should reflect in design the predominant use of deeply recessed, limited fenestration. In addition, verticality and a high proportion of mass to void should be incorporated. In areas characterized by newer buildings in concrete or stucco with industrial-style fenestration, new construction should reflect those design elements.

(3) Roof Treatment. Historically the view from Telegraph Hill over the Northeast Waterfront District has been one of roofs characterized by numerous regularly spaced industrial skylights. In renovation or new construction, these particular design features should be retained or incorporated.

(4) Signs shall be governed by the applicable provisions of Article 6, section 609.14, and this Appendix D. In the event of inconsistency among these provisions, the most restrictive provision shall prevail unless this Code specifically provides otherwise.

(c) Exterior Changes Requiring Approval. Exterior changes within the Northeast Waterfront Historic District shall require a Certificate of Appropriateness pursuant to the provisions of Article 10 when such work requires a city permit. In addition, a Certificate of Appropriateness shall be required for cleaning masonry surfaces with abrasives and/or treatment

of such surfaces with waterproofing chemicals. Sandblasting and certain chemical treatments detrimental to older brick will not be approved.

SEC. 5. STATEMENT OF SIGNIFICANCE.

(a) History of the area: For decades after the 1849 Gold Rush, San Francisco was the principal seaport and connection with the outside world for California and the West Coast. San Francisco's expansion and transformation into one of the most important cities in North America is attributable to the eminence of its port which, because of its sheltered location and deep water, became one of the best-suited on the Pacific Ocean.

The development of warehouses over a 120-year period along the southern waterfront provides a benchmark from which to view architectural and technological responses to the rapid changes of growing industrial nation state and city. The interdependence of architecture and history can be seen from a look at the evolution of warehouse forms along the southern waterfront. Unlike most other areas of the San Francisco waterfront, the South End District contains an extraordinary concentration of buildings from almost every period of San Francisco's maritime history. Several street fronts - such as Second, Third and Townsend - are characterized by solid walls of brick and reinforced concrete

warehouses. With this harmony of scale and materials, the South End Historic District is clearly a visually recognizable place.

One-story warehouses were common in the nineteenth century but rare in the early twentieth due to the increasing cost of land. Two of the oldest warehouses in the historic district are one story in height: Hooper's Warehouse (1874) and the California Warehouse (1882). Their horizontal orientation is accentuated through the use of strong cornice lines with decorative brick patterns.

Multi-story buildings have been more common along the southern waterfront since the turn of the century. After 1906, almost all new warehouses were constructed to be at least three stories in height, and several warehouses on Second and Townsend Streets reached six stories. The invention of the forklift in the 1930s eliminated advantages which multi-story buildings enjoyed over single-story structures. Since 1945, almost all warehouses constructed in the United States have been one story in height. Many multi-story warehouses and industrial buildings have been converted to other uses or are vacant because they have become obsolete for most warehouse or industrial functions.

South End's period of historical significance, 1867 to 1935, comprises the era during which the waterfront became a vital part of the City's and nation's maritime commerce. The buildings of the South End Historic District represent a rich and varied cross-section of the prominent local architects and builders of the period. Four buildings remain from the

nineteenth century; another four were constructed in the six-year interval preceding the 1906 earthquake. The majority of the buildings were erected between 1906 and 1929, a period during which trade along the waterfront increased dramatically.

Several events shaped this part of San Francisco. The building of Long Bridge in 1865 on the line of Fourth Street south to Point San Quentin or the Potrero district, opened up opportunities for new industrial development in the southern part of the city. The Second Street cut of 1869, through fashionable Rincon Hill, allowed access from downtown to the southern waterfront. The completion of the transcontinental railroad in 1869 (and the eventual extension of railway lines into the area) was the single most important event to impact the district. The fire of 1906 and the opening of the Panama Canal in 1914 were further impetuses to warehouse construction in this area, as were the seawall and the Belt Line Railway.

Prominent figures in San Francisco history have been associated with the district. William Ralston, founder of the Bank of California, builder of the Palace Hotel, and financier of San Francisco and the West, owned property in the district and was a major force in politically engineering the Second Street cut in 1869. William Sharon, a U.S. Senator from Nevada in 1875 - 1881, acquired much of Ralston's estate and also co-owned and built the California Warehouse on the corner of Second and Townsend for Haslett and Bailey in 1882.

William P. Aspinwall founded the internationally important Oriental Warehouse (Pacific Mail Steamship Company) in this district during the Gold Rush. John Hooper built Hooper's South End Grain Warehouse at Japan and Townsend Streets in 1874 for California's lucrative grain trade. Hooper was a member of a family known particularly for its lumber trade, with large land holdings just south of the South End Historic District.

John Hooper built Hooper's South End Grain Warehouse at Japan and Townsend Streets in 1874 for California's lucrative grain trade. Hooper was a member of a family known particularly for its lumber trade, with large land holdings just south of the South End Historic District.

The leading warehouse firms in San Francisco were those of the Haslett and Lamb families. Samuel Haslett, a native of Ireland, came to San Francisco in the 1870s and became a partner with J.W. Cox at the Humboldt Warehouse on Rincon Point. Haslett's sons continued the business after his death, and Samuel Haslett IV is now president of the firm. Once nationally known in warehousing, the Hasletts built or are associated with seven warehouses in the district. George Lamb founded the South End Warehouse Company in 1905, and later co-founded the drayage and hauling firm of King and Company. South End operated six warehouses in the area at various times.

Charles Lee Tilden (1857 - 1950) built 111 - 113 Townsend, a Haslett warehouse, and the Overland warehouse at Third and Townsend Streets. Tilden, a highly successful business entrepreneur, also founded the East Bay Regional Park system in 1934. Charles Norton Felton (1828 - 1914), Senator, Congressman, and early developer of oil in California, is associated with warehouses at 275 Brannan Street and 601 Second Street.

The proposed historic district is an important visual landmark for the City as a whole. The large number of intact masonry warehouses which remain to this day are reminders of the maritime and rail activities which helped to make San Francisco a great Turn-of-the-Century Port City. The warehouse district, because of its distinct building forms, is

identifiable from many parts of San Francisco and the greater Bay Area. Additional historical information may be found in the South End Historic District Case Report No. 89.065L. (Added by Ord. 104-90, App. 3/23/90)

SEC. 6. FEATURES.

1. Overall Form and Continuity. Building height is generally within a six-story range, and many of the oldest structures are one or two stories in height.

2. Scale and Proportion. The buildings are of typical warehouse design, large in bulk, often with large arches and openings originally designed for easy vehicular access. There is a regularity of overall form. The earlier brick structures blend easily with the scaled-down Beaux Arts forms of the turn of the century and the plain reinforced concrete structures characteristic of twentieth-century industrial architecture.

3. Fenestration. The earliest structures have few windows, expressing their warehouse function. They are varied in size, rhythmically spaced, deeply recessed, produce a strong shadow line, and relate in shape and proportion to those in nearby buildings. Larger industrial sash windows began to be incorporated in structures built from the 1920s and onward. Door openings are often massive to facilitate easy access of bulk materials.

4. Materials. Standard brick masonry is predominant for the oldest buildings in the district, with reinforced concrete introduced after the 1906 fire, although its widespread use did not occur until the 1920s. Brick and stone paving treatments on Federal and First and De Boom Streets respectively are extant as well as Beltline Railroad Tracks which run throughout the District.

5. Color. Red brick is typical, with some yellow and painted brick. Muted earth tones predominate in shades of red, brown, green, gray and blue.

6. Texture. Typical facing materials give a rough textured appearance. The overall texture of the facades is rough grained.

7. Detail. Arches are common at the ground floor, and are frequently repeated on upper floors. Flattened arches for window treatment are typical. Cornices are simple and generally tend to be abstract versions of the more elaborate cornices found in downtown commercial structures from the nineteenth century. Most of the surfaces of the later buildings are plain and simple reflecting their function. Some of the earlier brick work contains suggestions of pilasters, again highly abstracted. Where detail occurs, it is often found surrounding entryways.

• (b) Standards for New Construction and Alterations.

1. Facade Line Continuity. Facade line continuity is historically appropriate. Therefore, setbacks at lower floors and arcades, not generally being features of the South End Historic District, are generally not acceptable.

2. Fenestration and Design Elements for New Construction. In areas with a concentration of buildings characterized by a high proportion of mass to void and deeply recessed openings, vertical orientation and limited fenestration, the design of new construction should relate to those elements. In areas characterized by buildings with industrial style fenestration, new construction should relate to those design elements.

3. Signs.

(A) Principal Signs. Only one sign will be allowed per establishment per street frontage. A flush sign with lettering intended to be read from across the street is permitted. On brick surfaces, signs should be mounted with a minimum number of penetrations of the wall, and those penetrations only in the mortar joints.

(B) Secondary Signs. One per establishment per street frontage. A secondary sign is intended to be viewed closeup and consists of: (a) Lettering on a door or window which contains only the name and nature of the establishment, hours of operation and other pertinent information. (b) A projecting sign not exceeding two square feet in area used in conjunction with a principal flush sign.

(c) Exterior Changes Requiring Approval. Any exterior change within the South End Historic District shall require a Certificate of Appropriateness pursuant to the provisions of Article 10 when such work requires a city permit. In addition, a Certificate of Appropriateness shall be required for cleaning masonry surfaces with abrasives and/or treatment of such surfaces with waterproofing chemicals. Sandblasting and certain chemical treatments detrimental to older brick will not be approved.

(Added by Ord. 104-90, App. 3/23/90)

SEC. 7. ADDITIONAL PROVISIONS FOR CERTIFICATES OF APPROPRIATENESS.

The procedures, requirements, controls and standards in Sections 1006 through 1006.8 of Article 10 of the Planning Code shall apply to all applications for Certificates of Appropriateness in the South End Historic District. In addition, the following provisions shall apply to all such applications; in the event of any conflict or inconsistency between the following provisions and Article 10, those procedures, requirements, controls, and standards affording stricter protection to landmarks, landmark sites, and the Historic District shall prevail.

(a) Character of the Historic District. The standards for review of all applications for the Certificate of Appropriateness are set forth in Section 1006.7 of Article 10. For purposes of review pursuant to these standards, the character of the historic district shall mean the exterior architectural features as well as the historic brick and stone paving materials described in Section 6 of this ordinance.

(b) New Construction. New construction on vacant sites should conform to the general profile of the District, especially as to scale, sculptural qualities of facade and entrance detailing, fenestration patterns and materials described in Section 6 of this ordinance.

(c) Masonry, Brickwork and Stonework. A Certificate of Appropriateness shall be required for painting previously unpainted masonry, brick or stone exterior surfaces, for cleaning such surfaces with abrasives and/or treatment of such surfaces with waterproofing chemicals. Sandblasting and certain chemical treatment detrimental to masonry will not be approved.

(d) Alterations. It is recognized that certain alterations to the exteriors of buildings within the Historic District may be necessary in order to accommodate adaptive reuse of, and to provide sufficient light and air in, such buildings. Substantial alterations to Principal Facades, as defined in Planning Code Section 102, should be discouraged. Substantial alterations to non-principal facades, not originally intended to be viewed from the street, may be appropriate, provided such alterations maintain the character of the historic district.

(e) 200 Brannan Street, Lot 24 within Assessor's Block 3774 is a site proposed for high-density mixed-income housing within the Rincon Point-South Beach Redevelopment Project Area Plan. The subject property is a donut-shaped group of buildings of different dates behind a single unifying wall and the continuous facade wall which runs along the First and Brannan Streets is the contributory element of the site and adaptive reuse of the subject property is acceptable.

Undesignated introductory paragraph and division (d) amended; Ord. 202-18, Eff. 9/10/2018.

The history of each parcel within the Historic District is documented on the survey worksheets (Appendix A to the South End Historic District Case Report No. 89.065L). This classification of buildings in the South End Historic District is delineated in Case Report No. 89.065L. Each building is designated as one of the following:

1. Contributory.This category identifies buildings which date from the Historic District's period of significance and retain their historic integrity. These structures are of the highest importance in maintaining the character of the Historic District.

2. Contributory - Altered.This category identifies buildings which date from the historic district's period of significance but have had their historic integrity compromised by inappropriate alterations. Appropriate restoration of such buildings is encouraged. If a building in this category were to be appropriately restored, the category designation may be amended by the L.P.A.B. to "Contributory."

3. Noncontributory.This category identifies buildings which are outside the Historic District's period of significance or are so significantly altered that they have lost their integrity. A Certificate of Appropriateness shall not be required for demolition of a noncontributory building. Construction of new buildings on a demolished building site, additions to, and major alterations of noncontributory buildings should be compatible with the character of the Historic District, and would require a Certificate of Appropriateness in order to ensure compatibility with the character of the historic district. (Added by Ord. 104-90, App. 3/23/90)

Nothing in this legislation shall be construed as authorization to regulate paint colors used within the District.

(Added by Ord. 104-90, App. 3/23/90)

Additions to existing buildings and new infill construction proposed within the South End Historic District must reflect an understanding of the relationship of the proposal with the contributing buildings within the district. Additions shall be reviewed for compatibility with the historic building and the district while infill construction shall be reviewed for compatibility with the overall district. Neither should directly imitate nor replicate existing features. For additions, every effort should be made to minimize the visibility of the new structure within the district. Infill construction should reflect the character of the district, including the prevailing heights of contributing buildings without creating a false sense of history. Property owners should consult early in the process with a Planning Department Historic Preservation Technical Specialist when developing a proposal.

Additions will be reviewed on a case-by-case basis and any proposed addition should be located in an inconspicuous location and not result in a radical change to the form or character of the historic building. A vertical addition may be approved, depending on how the addition impacts the building and its relative visibility from the surrounding public rights-of-way within the district. The Planning Department evaluates all proposals for properties identified under Article 10 of the Planning Code for compliance with the Secretary of the Interior's Standards (36 C.F.R. § 67.7 (2001)). Based on these Standards, Department staff uses the following criteria when reviewing proposals for vertical additions:

• The structure respects the general size, shape, and scale of the features associated with the property and the district and the structure is connected to the property in a manner that does not alter, change, obscure, damage, or destroy any of the character-defining features of the property and the district.

• The design respects the general historic and architectural characteristics associated with the property and the district without replicating historic styles or elements that will result in creating a false sense of history.

• The materials are compatible with the property or district in general character, color and texture.

As part of the Planning Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the district. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

ing Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the district. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

When a district provides an opportunity for new construction through existing vacant parcels or by replacing noncontributing buildings, a sensitive design is of critical importance. Historic buildings within the district should be utilized and referenced for design context. Contemporary design that respects the District's existing character-defining features without replicating historic designs is encouraged. The Department uses the following criteria when reviewing proposals for infill construction:

• The structure respects the general size, shape, and scale of the character-defining features associated with the district and its relationship to the character-defining features of the immediate neighbors and the district.

• The site plan respects the general site characteristics associated with the district.

• The design respects the general character-defining features associated with the district

• The materials are compatible with the district in general character, color, and texture. (Added by Ord. 298-08, File No. 081153, App. 12/19/2008)

SEC. 5. STATEMENT OF SIGNIFICANCE.

The San Francisco Civic Center possesses a unique place and significance in the areas of architecture, history, and environment worthy of protection as an historic district.

The land on which the Civic Center stands was declared a City Hall Reservation as early as 1870. Portions of that reservation land were sold to raise funds for City Hall construction, and Old City Hall - located on the site that had first been used as the Yerba Buena Cemetery, approximately where the present library stands - was erected between 1871 and 1897, in a lengthy project marked by the now well known City government corruption of that time.

In 1899, B.J.S. Cahill, with the encouragement of Mayor Phelan, proposed a grander vision for the area, with the dual goal of clearing up land titles clouded by the dubious practices of the promoters of the Old City Hall and, at the same time, of creating an imposing setting for the entire area. This plan envisioned clearing out smaller structures and visually uniting

the remaining monumental structures - Old City Hall, the Main Post Office, the Hibernia Bank building, and other larger structures - and setting them off against new open spaces (such as a planned extension of the Golden Gate Park panhandle to Market Street). Conflicting new developments were blocked for a time, but the plan eventually failed, in large part because of general distrust - bred of experience, perhaps - of large government projects.

l, the Main Post Office, the Hibernia Bank building, and other larger structures - and setting them off against new open spaces (such as a planned extension of the Golden Gate Park panhandle to Market Street). Conflicting new developments were blocked for a time, but the plan eventually failed, in large part because of general distrust - bred of experience, perhaps - of large government projects.

Undaunted, former Mayor Phelan soon led the formation of an Association for the Improvement and Adornment of San Francisco. In 1904, the Association invited Daniel Burnham to design a grand plan for the City, with B.J.S. Cahill providing a design for the Civic Center. This produced two visions of the Civic Center: Cahill, with the practicality borne of personal and local experience, proposed using existing structures and City-owned land to create a central plaza, surrounded by major buildings, and, again, connected to a Golden Gate Park panhandle extension; Burnham proposed a grander Civic Center, with buildings connected by a generally circular series of boulevards and grand open vistas. The Burnham Plan, though politically impractical, fired the public imagination and was submitted to and adopted by the Board of Supervisors on September 27, 1905.

Following the 1906 earthquake, the public desire to rebuild and reclaim what had just been lost confirmed in practice what Cahill had perceived before: that political expediency set limits to the definition of the Civic Center. Competition continued between the different views of Burnham and Cahill of what the Civic Center might become, but by 1912 the Board of Supervisors had endorsed the Cahill Plan as modified in 1909. The momentum of growing civic pride and the Civic Center development effort - spearheaded by then-Mayor Rolph and the coming of the 1915 Panama-Pacific Exposition - was focused into the general outlines sketched by Cahill.

Mayor Rolph, a reform candidate, saw the Civic Center as a central civic improvement, the symbol of a new unity of the people under a new and honest political era and a permanent expression of the grandeur and vitality which the 1915 Exposition would exemplify on a temporary scale.

The World Columbian Exposition in Chicago, in 1893, was the source of inspiration for the "City Beautiful" movement which emphasizes formal plan and composition of monumental scale, neoclassical style buildings fronting plazas, boulevards and grand public gathering spaces. The order, harmony, cleanliness, and grandeur of the exhibition, called "The White City," was in sharp contrast to the rapid, chaotic growth that most U.S. cities had experienced in the preceding era of rapid immigration and industrialization.

ich emphasizes formal plan and composition of monumental scale, neoclassical style buildings fronting plazas, boulevards and grand public gathering spaces. The order, harmony, cleanliness, and grandeur of the exhibition, called "The White City," was in sharp contrast to the rapid, chaotic growth that most U.S. cities had experienced in the preceding era of rapid immigration and industrialization.

Several world's fairs were held throughout the country in the later 1800's, spreading the ideals of classical architecture, Beaux Arts forms, and the concepts of planning and cooperation for ensemble effect in design. These planning and design schemes were an important influence for forty years, with their primary manifestation coming in designs for cities, parks, and civic centers. Numerous City plans were commissioned in the early years, but only Cleveland and San Francisco implemented a portion of their plans, with San Francisco more nearly reaching completion.

The historic significance of the "City Beautiful" movement lies in the manner in which it reformed and refocused architectural vision, contributing to something of a national style of architecture; and, on a practical level, in the formation of City Planning Departments and schools or courses devoted to City Planning.

The design of the San Francisco Civic Center is an example of the development of those significant contributions. More particularly, the San Francisco Civic Center is an expression of a nation ready to display its new international importance in an architectural statement. At the time it took form, geography and historical events had made San Francisco the center of western America. Monumental classical architecture for the City's central public space expressed this consciousness, as well as the accompanying belief that such inspiring surroundings should be democratically available to all, not just a privileged few.

The Exposition Auditorium, the Central Plaza, and the Powerhouse were completed before the 1915 Panama-Pacific Exposition, and the new City Hall was completed in late 1915. The library was completed in 1916; the State Building in 1921; and the Public Health Building in 1932 and the Old Federal Building in 1936. The present Opera House and Veterans Building expanded the Civic Center to the west in 1932 and 1933, respectively, much in the manner the original proponents envisioned. The original plaza was excavated in 1956 to add the underground parking garage. At this time the ground level details were changed into the present reflecting pool and semi-park. United Nations Plaza, which opens the

vista to the east of City Hall in a manner consistent with the original vision of the Civic Center, was created in the mid1970's.

It is an exemplary City Beautiful complex in the best of the American Academic Beaux Arts tradition. Designed and built in the revival of classical style, stemming from the Chicago World's Fair of 1893 that has been called the "American Renaissance," it succeeds in making a strong impression of Civic dignity and pride. The San Francisco Civic Center Historic District consists of a principal aggregation of monumental buildings around a central open space, with additional buildings extending the principal axis at either end. It includes all or part of the fifteen City blocks. There are eight major buildings, a group of secondary buildings, three unrealized building sites, and a large plaza within the Historic District.

Each building in the Civic Center was faced with the problem of providing modern, functional facilities in a classical idiom. The classical Beaux Arts style was deemed suitable as the traditional style of American governmental buildings, and was amenable to City Beautiful ideals of harmony among many buildings on a grand scale. The formal composition of "City Beautiful" architecture, plantings, street embellishments and plazas was meant to be an expression of civic authority and pride - intending to impress and overawe. The classical style aptly expressed the mood of a nation eager to redefine its newly achieved international importance in architectural terms. It reflected a mood and an existing state of affairs as much as an inspiration to dominance. In San Francisco, it represented the city's emergence as a regional center of national importance, and within the City, it symbolized the united efforts of a population recently divided along many lines.

In terms of "democratic" architecture, or architecture for an ever larger segment of the population, monumental classical architecture uncompromisingly demonstrated the enhanced concern for the general public. Only a few years earlier, such splendor was exclusively reserved for the rich and the privileged few. To this day, no greater public interiors have been built in the United States than those influenced by and representative of the City Beautiful Movement, including among the very finest, the San Francisco City Hall.

Within the scope of turn of the century classical architecture in the United States, the San Francisco Civic Center contains several fine examples of the mode and one superlative example in its City Hall. The other buildings in the group, although less interesting individually cannot properly be evaluated in the same way. In particular, the State Building, the Federal Building, the Health Building and the War Memorial group would probably appear rather dull compared to City Hall, as if they were missing an essential ingredient. But seen in the context of the Civic Center as a whole, and in relation to City Hall, all the buildings together achieve distinction.

But seen in the context of the Civic Center as a whole, and in relation to City Hall, all the buildings together achieve distinction.

The criteria on which the buildings are judged, then, must be the degree to which each enhances the group without distracting from City Hall. These qualities are achieved through a harmony of color, material, scale, size, texture, rhythm and style. Within these constrictions the buildings achieve individual interest through the imaginative manipulation of the elements.

The historic Civic Center buildings are unified in the Beaux Arts classical design. They are organized into horizontal bands of vertically proportioned elements, with the grand order of the facade displayed on two or three floors above a usually rusticated base of one or two ground and partially sub-ground floors. Civic Center Historic District contains standard features such as overall form, massing, scale, proportion, orientation, depth of face, fenestration and ornamentation, materials, color, texture, architectural detailing, facade line continuity, decorative and sculptural features, street furniture, granite curbing and grille work.

The Civic Center is designated as both a National Historic Landmark District and a Historic District on the National Register of Historic Places, the former designation occurred on February 27, 1987, the latter, October 10, 1978. These designations offer recognition that certain properties within the Historic District are worthy of preservation and alterations undertaken both in the local and federal districts shall comply with the Secretary of the Interior's Standards for the Treatment of Historic Properties. Said Standards were adopted by the Landmarks Preservation Advisory Board at its Regular Meeting of October 2, 1985, the amended Standards were readopted by the Landmarks Board at its Regular Meetings of February 6, 1991 and August 3, 1994.

The history of each parcel within the Historic District is documented in Appendix A: Survey of Parcels, and is included in the San Francisco Civic Center Historic District Case Report as readopted by the Landmarks Board on October 6, 1993 by Resolution No. 454 and as amended and readopted by the City Planning Commission on July 7, 1994 by Resolution No. 13719 and is located in Board of Supervisors File No. 115-94-10.

Each building is assigned a finding from the three following categories:

1. Contributory.This category identifies buildings which date from the Historic District's period of significance (1906 to 1936) which reflect a Beaux Arts style and which retain their historic and architectural integrity. These structures are of the highest importance in maintaining the character of the Historic District. Recognizing the unique character of this Historic District which is derived from its expression of an historic plan, some structures within the Historic District may date from the Historic District's period of significance but do not contribute to the intended original plan in their architecture, detailing, height or scale. Such buildings are designated noncontributory and may be considered for replacement with structures designed in a monumental style and manner which would complete the San Francisco Civic Center Plan as originally conceived.

The following buildings are deemed Contributory to the Historic District: Newton Tharp Commercial High School, 170 Fell Street, Lot 1 within Assessor's Block 815; (a portion of Landmark No. 140), Federal Building, 50 Fulton Street, (50 United Nations Plaza) Lot 35 within Assessor's Block 351; Exposition Auditorium, 99 Grove Street, Assessor's Block 812; Department of Public Health, 101 Grove Street/50 Ivy/Lech Walesa Street, Lot 1 in Assessor's Block 811; San Francisco Public Library, 200 Larkin Street, Lot 1 in Assessor's Block 353; Orpheum Theater Building, 1182 - 92 Market Street, Lot 22 in Assessor's Block 351; 1212 Market Street, Lot 3 in Assessor's Block 355; 1240 - 1242 Market Street, Lot 6 in Assessor's Block 355; Hotel Avalon, 1272 - 1276 Market Street, Lot 9 in Assessor's Block 355; 1278 - 1298 Market Street, Lot 10 in Assessor's Block 355; Methodist Book Concern, 83 McAllister Street, Lot 32 in Assessor's Block 351; Old State Office Building, 50 McAllister Street, Lot 2 in Assessor's Block 765; Barbara Apartments, 580 McAllister

Street, Lot 8 in Assessor's Block 767; 1 United Nations Plaza (35 - 57 Fulton Street); Lot 37 in Assessor's Block 351; the High School of Commerce, 135 Van Ness Avenue, (a portion of Landmark No. 140), Lot 1 in Assessor's Block 815; War Memorial Opera House, 301 Van Ness Avenue (a portion of Landmark No. 84), Lot 1 in Assessor's Block 786; San Francisco City Hall, 400 Van Ness Avenue (Landmark No. 21), Lot 1 in Assessor's Block 787; War Memorial Veteran's Building, 401 Van Ness Avenue (a portion of Landmark No. 84), Lot 1 in Assessor's Block 786; and, the Corinthian Court Apartments, 500 - 524 Van Ness Avenue, Lot 6 in Assessor's Block 766.

ra House, 301 Van Ness Avenue (a portion of Landmark No. 84), Lot 1 in Assessor's Block 786; San Francisco City Hall, 400 Van Ness Avenue (Landmark No. 21), Lot 1 in Assessor's Block 787; War Memorial Veteran's Building, 401 Van Ness Avenue (a portion of Landmark No. 84), Lot 1 in Assessor's Block 786; and, the Corinthian Court Apartments, 500 - 524 Van Ness Avenue, Lot 6 in Assessor's Block 766.

2. Contributory/Altered.This category identifies buildings which date from the Historic District's period of significance and have had alterations as detailed on page 22 of the San Francisco Civic Center Historic District Case Report located in Board of Supervisors File No. 115-94-10. Appropriate restoration of such buildings is encouraged, though in certain situations (see No. 1 above) their demolition and replacement may be more appropriate in order to achieve completion of the original San Francisco Civic Center plan. Such replacement should adhere to any Civic Center Urban Design Guidelines adopted by the City Planning Commission.

The following buildings shall be deemed Contributory/Altered within the Historic District: Marye Building, 12001208 Market Street, Lot 15 in Assessor's Block 355; 1220-1232 Market Street (29 Grove Street), Lot 4 in Assessor's Block 355; 1236 Market Street (37 - 39 Grove Street), Lot 5 in Assessor's Block 355; the Wells Fargo Building, 1256 - 1264 Market Street, Lot 8 in Assessor's Block 355.

3. Noncontributory.This category identifies buildings which post-date the Historic District's period of significance or have had their integrity compromised by inappropriate alterations as detailed on page 21 of the San Francisco Civic Center Historic District Case Report. Demolition permit applications for these buildings will be processed without reference to the suspension provisions of Article 10. Alterations to Noncontributory buildings will require Certificate of Appropriateness if determined to be a major alteration in order to minimize conflicts with the historic character of the Historic District. Replacement buildings should adhere to Civic Center Urban Design Guidelines adopted by the City Planning Commission.

Any replacement building should adhere to Civic Center Urban Design Guidelines adopted by the City Planning Commission. (Added by Ord. 413-94, App. 12/23/94)

SEC. 12. CERTIFICATES OF APPROPRIATENESS FOR CITY HALL ALTERATIONS.

Section 1006.8(e) of the City Planning Code describes the process for review of Certificate of Appropriateness applications proposing alterations to City Hall, Landmark No. 21. Nothing in this legislation shall be construed to amend said Section 1006.8(e). Said process shall serve to meet the Certificate of Appropriateness requirement for City Hall by its inclusion in this Historic District.

(Added by Ord. 413-94, App. 12/23/94)

Nothing in this legislation shall be construed to regulate paint colors within the Historic District. Painting of previously unpainted masonry and stone surfaces is discouraged.

(Added by Ord. 324-91, App. 9/4/91)

SEC. 5. STATEMENT OF SIGNIFICANCE.

The Bush Street - Cottage Row Historic District is a remarkably intact group of architecturally consistent Italianate and Stick residential buildings constructed between 1870 and about 1885. It demonstrates several different modes of speculative housing during those years, from the mass builder The Real Estate Associates, which developed whole square blocks, through investors John H. Smyth and Charles L. Taylor, who built houses to hold and rent out for income, to the single homeowner. This District is rated high on local surveys and is listed in the National Register of Historic Places.

The Bush Street - Cottage Row Historic District comprises 22 residences, a walkway and a small park. There is continuity of height and setback; houses step downhill evenly from the northeast to conform with the land contour; lots are narrow and deep. Almost all the houses were developed in four groups, so that six on Bush Street are essentially identical to each other, as are three different ones on Bush Street, two on Sutter Street and six on Cottage Row. All are two-story frame structures of Italianate or early Stick Style, with channel rustic siding, double-hung windows and paneled entry recess. They are tall, narrow buildings with tall, narrow openings balanced by heavy, bracketed cornices on patently false fronts. All except Cottage Row have bay windows on facade or rear.

Since they were originally built, the houses continued to be used as residences, with some alteration due to subdivision into units. At least two residences were resurfaced, and one of these has been restored. The walkway of Cottage row continued until 1944 as part of a single piece of private property with 2109 - 2113 Bush Street and 1 - 6 Cottage Row. The Cottage Row houses were separated into individual ownerships gradually from 1956 - 1967, and only on the last date was the walkway singled out as an individual holding separate from any house. Taylor himself had chosen the name "Cottage Row," which was listed among San Francisco's streets as early as the 1886 Directory. In the 1930s the walkway was popularly called "Japan Street," because the entire District was inhabited by Japanese-Americans until their internment during World War II. In the tiny rear yards of Cottage Row they grew vegetables, which they offered for public sale at an informal weekly open market held every Saturday along the Row. (Added by Ord. 324-91, App. 9/4/91)

SEC. 6. FEATURES OF EXISTING BUILDINGS.

1. Overall Form and Continuity.The massing of the existing buildings relates to the topographical contour of the site, and is compatible with the adjacent area.

2. Scale and Proportion.Buildings in the District relate to the height and setback of the structures immediately adjacent

• and in the general area, contained within an envelope that slopes upward or downward with the slope of the properties.

3. Fenestration.Existing fenestration is predominantly double-hung wooden sash and is proportionate and in scale with 19th century stylistic patterns within the District.

4. Materials.Horizontal rustic wood siding is the traditional cladding material in the District.

5. Detail.Detailing found in the district usually follows simple, straightforward Italianate or Stick Style forms. (Added by Ord. 324-91, App. 9/4/91)

SEC. 7. ADDITIONAL PROVISIONS FOR CERTIFICATES OF APPROPRIATENESS.

The following provisions shall apply to all applications for Certificates of Appropriateness in the Bush Street-Cottage Row Historic District in addition to the procedures, requirements, controls and standards of Article 10 and this Code. If any conflict or inconsistency between the following provisions and Article 10 arises, the procedures, requirements, controls and standards affording stricter protection to the landmark, landmark site, or Historic District shall prevail.

A. Character of the Historic District. The standards for review of all applications for Certificates of Appropriateness are set forth in Section 1006.7 of Article 10. For purposes of review pursuant to these standards, the character of the Historic District shall mean the exterior architectural features, Cottage Row right-of-way, and the Cottage Row Mini Park of the Bush Street-Cottage Row Historic District described in Section 6.

B. Exterior Changes Requiring Approval. A Certificate of Appropriateness shall be required for all exterior changes within the Historic District that are visible from a public street, the Cottage Row right-of-way, or the Cottage Row Mini Park. Such exterior changes requiring approval shall include, but not be limited to, the installation or replacement of fences, retaining walls, windows, security grates, lighting fixtures, and other building features visible from the public way.

C. Additions, Alterations, or New Construction. Additions, exterior alterations, and new construction shall be compatible with the scale, architectural details, fenestration, and materials of the District as described in this Appendix K. Any new work shall be compatible with the historic materials, features, size, scale, proportions and massing. New or replacement fences shall be compatible with the scale, height, materials, details, and topography of the Historic District.

D. Street and Park Furniture. Any new or replacement street or park furniture, including but not limited to light fixtures and trash receptacles, shall require a Certificate of Appropriateness.

E. Nothing in this legislation shall be construed to regulate paint colors within the Historic District. (Added by Ord. 148-09, File No. 081251, App. 7/10/2009)

SEC. 8. SIGNIFICANCE OF INDIVIDUAL BUILDINGS TO THE HISTORIC DISTRICT.

The history of each parcel within the Historic District is documented on survey worksheets (Appendix A to the Bush Street - Cottage Row Historic District Case Report No. 90.288L). This classification of buildings in the Historic District is delineated in the Case Report No. 90.288L. Each building is designated as follows:

(1) Contributory. This category identifies buildings which date from the Historic District's period of significance and retain their historic integrity. These structures are of the highest importance in maintaining the character of the Historic District. All buildings identified within this Historic District are Contributory to the Historic District.

(2) Noncontributory. This category identifies buildings or vacant lots which are outside or are not relevant to the Historic District's period of significance or are so significantly altered that they have lost their historic integrity. Construction of new buildings on a demolished or vacant sites and additions to or major alteration of Noncontributory buildings should be compatible with the character of the Historic District. Vacant parcels, including the City-owned rightof-way known as Cottage Row (Lot 46) and the City-owned Mini Park (Lot 12), are both rated Noncontributory. (Added by Ord. 324-91, App. 9/4/91)

SEC. 5. STATEMENT OF SIGNIFICANCE.

The Dogpatch Historic District possesses a unique place and significance in the areas of architecture, history, and environment worthy of protection as an historic district. Dogpatch is an approximately nine-block enclave of industrial workers' housing located east of Potrero Hill, in San Francisco's Central Waterfront district. The neighborhood is comprised of almost one-hundred flats and cottages, as well as several industrial, commercial, and civic buildings, most of which were erected between 1870 and 1930.

nvironment worthy of protection as an historic district. Dogpatch is an approximately nine-block enclave of industrial workers' housing located east of Potrero Hill, in San Francisco's Central Waterfront district. The neighborhood is comprised of almost one-hundred flats and cottages, as well as several industrial, commercial, and civic buildings, most of which were erected between 1870 and 1930.

The neighborhood is significant under National Register Criterion A (Events/Patterns of History) and Criterion C (Design/Construction). The neighborhood is significant at the local level under Criterion A (Events/Patterns of History), within the category of Industry, as the oldest and most intact concentration of industrial workers' housing in San Francisco. No other district of San Francisco or California was industrialized to the degree of Potrero Point during the last quarter of the 19th Century. The shipyards and other maritime-related industries of Potrero Point required a steady supply of inexpensive immigrant labor in an area that was geographically cut off from the rest of the City. Local developers and landholders, including Santa Fe Land Improvement Company, responded to this need by constructing rows of inexpensive cottages and selling individual parcels to laborers and their families, allowing the neighborhood to develop as an informal

company town. Dogpatch is also significant at the local level under Criterion A (Events/Patterns of History), within the category of Exploration/Settlement, as the first housing developed in the Potrero District. Initially developed in the early 1870s, Dogpatch became the nucleus of the Potrero District that would evolve after the 1906 earthquake. Finally, Dogpatch is significant under Criterion C (Design/Construction), within the category of Architecture, as a moderately intact district of mostly Victorian and Edwardian-era workers' dwellings constructed between 1870 and 1910. Residences within the district reflect vernacular forms of architectural styles that were prevalent throughout the country, including Greek Revival, Queen Anne, Italianate, Eastlake and Classical Revival styles, or combinations thereof. The district has several clusters, and pairs of identical dwellings, including a group of thirteen identical Eastlake-style cottages based on the plans of San Francisco architect John Cotter Pelton, Jr. While the significance of Union Iron Works/Bethlehem Steel is national in scope, the significance of Dogpatch under this criterion remains local.

The period of significance for the district dates from 1867, the opening of Long Bridge and the beginning of construction in the neighborhood, to 1945, the end of World War II. Additional historic information may be found in the Dogpatch Historic District Designation Report, which is hereby incorporated herein as though fully set forth. This document is on file at the Planning Department under Case No. 2002.99775L. (Added by Ord. 66-03, File No. 020972, App. 4/18/2003)

SEC. 6. FEATURES.

(a) Residential - Features of Existing Buildings.

1. Overall Form and Continuity.Building height is generally within a three-story range, with a substantial number of structures built at one or two stories in height. The majority of structures have been either elevated or altered to allow for the construction of a garage level at grade. However, despite these and other alterations, the majority of residences in the district retain their historic integrity. Residential buildings are generally set back an average of 10 feet from the public right-of-way.

2. Scale and Proportion.The buildings vary in height, bulk, scale and proportion. The width of lots in Dogpatch range from single lots of 20 feet to 40 feet for larger lots. Early homes in Dogpatch constructed circa 1870 were designed in a vernacular style with Greek Revival influences. Later homes continued in the Greek Revival form, but were joined by homes designed in the Queen Anne, Italianate and Classical Revival styles, as well as the Eastlake-styled Pelton Cottages. Multi-story residences are large in bulk, often as great as 3,500 square feet. Smaller cottage-size structures, typically 800 square feet, are well scaled to the smaller lots.

3. Fenestration.Existing fenestration consists of predominantly double-hung, wood sash windows that are vertical in orientation. Residential buildings feature a fairly symmetrical and regular pattern of windows with consistent dimensions along primary facades. Generally, the size and shape of window openings have not been altered over time.

4. Materials.Horizontal rustic wood siding is the traditional cladding material found in the district. However, fishscale wood shingles and asbestos siding are also found throughout the district.

5. Design Features.Recessed porches and entry porticos are characteristic design features of the district.

6. Architectural Detail.Architectural detail found in the district usually follows transitional elements associated with the Greek Revival, Eastlake, Queen Anne, Italianate and Classical Revival architectural styles.

(b) Industrial/Commercial - Features of Existing Buildings.

1. Overall Form and Continuity.Building height is generally within a four-story range and many of the

industrial/commercial structures are one or two stories in height. Typically, these buildings are constructed closer to the property line than the residential structures found in the district.

2. Scale and Proportion.The buildings are of typical warehouse design, large in bulk, often with large, ground level openings originally designed for rail or vehicular access. Industrial/commercial structures are found throughout the district, often surrounded by residential buildings. While gaps may exists, because of height, bulk and setback, there is regularity to the overall form of industrial/commercial buildings. A small cluster of brick and stucco public buildings

in bulk, often with large, ground level openings originally designed for rail or vehicular access. Industrial/commercial structures are found throughout the district, often surrounded by residential buildings. While gaps may exists, because of height, bulk and setback, there is regularity to the overall form of industrial/commercial buildings. A small cluster of brick and stucco public buildings

(police, fire, and hospital) are easily recognizable from other industrial/commercial structures found in the district. These resources, while offering a different scale and proportion, are compatible with the plain reinforced concrete and brickfaced structures characteristic of 20th century industrial architecture.

3. Fenestration.For the most part, the district's industrial/commercial buildings lack strong fenestration patterns, which typically are not supportive of a warehouse function. Windows exist near entrances and in some cases, offer small storefronts to display products. Early 20th century warehouse buildings were often constructed with office spaces above warehouse functions. In this case, double-hung, residential-type windows can be found. Larger industrial, metal sash windows are prevalent on commercial buildings built after 1920. Door openings are often massive to facilitate easy access of bulk materials.

4. Materials.Standard brick masonry is found on the older industrial/commercial buildings in the district; reinforced concrete was introduced as a cladding material following the earthquake and fire of 1906. Concrete block and stucco are also found on some 20th century, industrial/commercial buildings.

5. Color.Red brick is typical, with some yellow and painted brick. Muted earth tones of red, brown, green, gray, and blue are found on reinforced concrete, concrete block, and stucco-faced buildings.

6. Texture.Typical facing materials give both a rough textured or smooth appearance, depending on the cladding material.

7. Architectural Detail.Industrial and commercial buildings typically lack ornamentation. Warehouses by their very nature are utilitarian; warehouses constructed towards the end of the Dogpatch Historic District period of significance (1943) have even less ornamentation than older counterparts. Cornices are simple and may be abstract versions of more elaborate cornices found on larger, commercial structures in San Francisco's Financial District. Where detail occurs, it is often found surrounding entryways to industrial/commercial buildings. (Added by Ord. 66-03, File No. 020972, App. 4/18/2003)

SEC. 7. STANDARDS FOR REVIEW OF APPLICATIONS.

Any exterior change within the Dogpatch Historic District shall require a Certificate of Appropriateness, pursuant to the provisions of Article 10, when such work requires a City permit. The procedures, requirements, controls and standards of Article 10 of the Planning Code shall apply to all applications for Certificates of Appropriateness in the Dogpatch Historic District. In addition, the following specific standards for review shall apply to all applications for Certificates of Appropriateness. In the event of any conflict or inconsistency between the provisions set forth below and Article 10, those procedures, requirements, controls and standards affording stricter protection to the Historic District shall prevail.

(a) Character of the Historic District. The general standards for review of all applications for Certificates of Appropriateness are as set forth in Article 10. For purposes of review pursuant to said standards, the character of said Historic District shall mean the features of the Dogpatch Historic District referred to and described in Section 6 of this ordinance. For projects on buildings that have been previously compromised by incompatible alterations or additions, proposed exterior changes which bring these buildings closer to their original, historic appearance and make the buildings more in conformity with the character of the district are encouraged.

(b) Residential - Alterations and New Construction. Exterior alterations or new additions to a contributory or noncontributory residential resource in the Dogpatch Historic District shall not destroy historic materials that characterize the resource or its environs. New additions, exterior alterations, or related new construction shall not destroy historic materials, features and spatial relationships that characterize the property. Any new work shall be differentiated from the old and shall be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment, and must conform to the following provisions:

1. False Historicism.False historicism and the conjectural replication of historic styles and details is discouraged; if restoration is the selected alteration approach, historic documentation through original architectural plans, historic photographs, or physical investigation will be required. Where original plans or historic photographs are unavailable, close

physical examination of the building and existing scar traces, along with a comparison to buildings of the same age and style in the neighborhood, may be sufficient to reveal evidence necessary to guide the restoration.

2. Materials.Horizontal rustic wood siding is the traditional cladding material in the district and its use is encouraged over other cladding materials, including wood shingles (except where appropriate).

3. Fenestration.Fenestration should be proportionate and in scale with traditional patterns within the district. Doublehung wood sash windows are encouraged over vinyl or metal sash windows. "Slider" windows of vinyl or aluminum construction are discouraged, especially on primary facades. True divided lites, rather than snap-in or faux muntins, are encouraged when divided lite wood windows are appropriate.

4. Style.New construction in a contemporary, yet compatible, idiom is encouraged.

5. Scale and Proportion.New construction must be compatible with the massing, size, scale and architectural details of residential resources found in the district.

6. Setbacks.New construction should conform to existing setback patterns found in the district.

7. Roofline.Gabled roof forms and raised parapets are encouraged on new construction.

8. Detailing.Detailing on new construction should relate to the simple, traditional vernacular forms found in the district.

(c) Industrial/Commercial - Alterations and New Construction. Exterior alterations or new additions to a

contributory or non-contributory industrial/commercial resource in the Dogpatch Historic District shall not destroy historic materials that characterize the resource or its environs. New additions, exterior alterations, or related new construction shall not destroy historic materials, features and spatial relationships that characterize the property. Any new work shall be differentiated from the old and shall be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment, and must conform to the following provisions:

1. Materials.The traditional cladding materials of industrial/commercial structures found in the district are brick, reinforced concrete, cinder block, and stucco; they are encouraged over other cladding materials.

2. Fenestration.Fenestration should be proportionate and in scale with traditional patterns within the district. Wood or metal sash windows are encouraged, while"slider" windows of vinyl or aluminum construction on either industrial or commercial buildings are discouraged.

3. Roofline.Flat roof forms are encouraged on industrial and/or commercial structures; gabled roof forms may be appropriate for commercial structures that include residential upper floors.

4. Parapets.Raised parapets are typically found on industrial and/or commercial structures in the Dogpatch Historic District and are encouraged where appropriate. Parapets should be kept to a minimum height necessary to screen rooftop equipment, or to facilitate characteristic design features.

5. Design Features.The addition of bay windows, porches, balconies or other typically residential features to new or existing industrial/ commercial structures in the district are discouraged. These elements may be appropriate on commercial structures that include residential upper floors.

6. Style.New construction in a contemporary, yet compatible, idiom is encouraged.

7. Scale and Proportion.New construction must be compatible with the massing, size, scale and architectural details of industrial/commercial resources found in the Dogpatch Historic District.

8. Setbacks.New construction should conform to existing setback patterns found in the district.

9. Detailing.Detailing on new construction should relate to the simple, traditional vernacular forms found on industrial/commercial structures in the district.

(d) Ordinary Maintenance and Repair. A Certificate of Appropriateness shall not be required if the work consists of ordinary maintenance and repair, which is defined in Article 10 as any work the sole purpose and effect of which is to correct deterioration, decay or damage, including repair of damage caused by fire or other disaster.

• (e) Garages and Garage Doors. The addition of garages at the front elevation of residential buildings shall seek to minimize the physical and visual impacts on the significant architectural features of the existing building. The design of

garages and garage doors should be unobtrusive and simple, with an emphasis on minimal size and dimensions of the structure as well as the door opening. Garage doors should be recessed from the garage structure to create an adequate shadow line, with wood being the preferable material. While remaining simple and unobtrusive, the design of the garage door may relate to the existing residence in material, detail and orientation. Retention of historic side-hinged garage doors is encouraged.

(f) Masonry, Brickwork and Stonework. A Certificate of Appropriateness shall be required for painting previously unpainted masonry, brick or stone exterior surfaces, for cleaning such surfaces with abrasives and/or treatment of such surfaces with waterproofing chemicals. The painting of unpainted masonry, brickwork and stonework is discouraged. Sandblasting and certain chemical treatment detrimental to masonry will not be approved.

(g) Demolition. Demolition of Contributory buildings shall be subject to the maximum controls allowed under Article 10 of the Planning Code. A demolition permit shall not be issued until all other required permits for new replacement construction have been approved. No application for a demolition permit shall be deemed complete until all building permits for the replacement structure, preferably located on the demolition site, have been approved.

shall be subject to the maximum controls allowed under Article 10 of the Planning Code. A demolition permit shall not be issued until all other required permits for new replacement construction have been approved. No application for a demolition permit shall be deemed complete until all building permits for the replacement structure, preferably located on the demolition site, have been approved.

(h) Seismic Upgrade. Seismic upgrades shall seek to minimize the alteration of the significant architectural features of a structure. Proposed Unreinforced Masonry Building (UMB) upgrades should follow the "Architectural Design Guide for Exterior Treatments of Unreinforced Masonry Buildings during Seismic Retrofit," prepared by the American Institute of Architects. When enforcing the terms of this provision during seismic upgrade work, due consideration shall be given to approving modest alterations for seismic upgrade purposes when enforcing the terms of these provisions, for example, the replacement of relatively unobtrusive building elements such as a brick foundation on a wood frame building.

SEC. 8. SIGNIFICANCE OF INDIVIDUAL BUILDINGS TO THE HISTORIC DISTRICT.

An architectural description, building history and evaluation of each parcel within the Historic District is documented on the State of California - Department of Parks and Recreation Primary Record (DPR 523A - descriptive) survey forms and Building, Structure, and Object Record (DPR 523B - evaluative) survey forms. These forms are part of the Dogpatch Historic Resource Survey which was endorsed by the Landmarks Board on October 17, 2001 (Resolution No. 545), and then by the Planning Commission on December 13, 2001 (Resolution No. 16300). These survey forms are hereby incorporated herein as though fully set forth, and is [sic] on file at the Planning Department under Case No. 2002.0775L. It is important to note that street address numbers are subject to change, and that the most reliable, official method for identifying a property within the Historic District is to refer to it by its assigned Assessor Block and Lot number. Each building is assigned to either of the two following categories.

Contributory.This category identifies buildings, which date from the Historic District's period of significance and retain their historic integrity. These structures are of the highest importance in maintaining the character of the Historic District. The category also includes buildings which date from the Historic District's period of significance, but have had their historic integrity compromised by inappropriate alterations. Appropriate restoration of such buildings is encouraged. The maximum suspension period allowable under Article 10 shall be imposed on applications for demolition of Contributory buildings.

ter of the Historic District. The category also includes buildings which date from the Historic District's period of significance, but have had their historic integrity compromised by inappropriate alterations. Appropriate restoration of such buildings is encouraged. The maximum suspension period allowable under Article 10 shall be imposed on applications for demolition of Contributory buildings.

The following buildings are deemed Contributory to the Historic District: 2300 3rd St., 2310 3rd St., 2342 - 44 3rd St., 2476 - 78 3rd St., 2500 - 02 3rd St., 2518 - 20 3rd St., 2620 3rd St., 2624 - 26 3rd St., 2628 - 32 3rd St., 2636 - 38 3rd St., 707 18th St., 700 - 02 22nd St., 714 22nd St., 718 22nd St., 726 - 32 22nd St., 800 - 02 22nd St., 806 22nd St., 807 22nd St., 808 - 10 22nd St., 812 - 14 22nd St., 816 - 18 22nd St., 820 - 24 22nd St., 825 - 29 22nd St., 833 22nd St., 834 - 40 22nd St., 845 & 849 22nd St., 894 - 98 22nd St., 900 - 02 22nd St., 904 - 22 22nd St., 890 - 900 Minnesota St., 903 Minnesota St., 905 Minnesota St., 907 Minnesota St., 909 Minnesota St., 911 Minnesota St., 913 Minnesota St., 914 - 16 Minnesota St., 915 Minnesota St., 917 - 919 Minnesota St., 918 Minnesota St., 920 - 22 Minnesota St., 921 Minnesota St., 923 Minnesota St., 924 - 26 Minnesota St., 930 - 32 Minnesota St., 934 Minnesota St., 944 - 46 Minnesota St., 945 - 47

Noncontributory.This category identifies buildings which postdate the Historic District's period of significance. Demolition permit applications for these buildings will be processed without reference to the suspension provisions of Article 10. Alterations to Noncontributory buildings would require Certificate of Appropriateness review in order to ensure that alterations and new construction would be compatible with the historic character of the District in terms of scale, massing, fenestration, materials and detail.

n permit applications for these buildings will be processed without reference to the suspension provisions of Article 10. Alterations to Noncontributory buildings would require Certificate of Appropriateness review in order to ensure that alterations and new construction would be compatible with the historic character of the District in terms of scale, massing, fenestration, materials and detail.

The remaining buildings shall be deemed to be Noncontributory within the Historic District: 2514 3rd Street, 2604 - 08 3rd Street, 2642 - 46 3rd Street, 795 22nd St., 798 22nd St., 825 Minnesota St., 910 - 12 Minnesota St., 670 - 72 Tennessee St., 674 - 82 Tennessee St., 690 Tennessee St., 748 - 50 Tennessee St., 760 Tennessee St., 780 Tennessee St., 790 Tennessee St., 870 - 90 Tennessee St., 901 Tennessee St., 991 Tennessee St., 993 Tennessee St., 1001 Tennessee St., 1005 Tennessee St., 1006 Tennessee St., 1007 Tennessee St., 1009 Tennessee St., 1025 Tennessee St., 1069 Tennessee St., 1117 - 19 Tennessee St., 1120 - 22 Tennessee St., 1121 - 23 Tennessee St., 1124 - 28 Tennessee St., 1129 - 31 Tennessee St., 1167 - 69 Tennessee St., 1191 - 93 Tennessee St.

SEC. 9. PAINT COLOR.

Nothing in this legislation shall be construed to regulate paint colors within the District. (Added by Ord. 66-03, File No. 020972, App. 4/18/2003)

Additions to existing buildings and new infill construction proposed within the Dogpatch Historic District must reflect an understanding of the relationship of the proposal with the contributing buildings within the district. Additions shall be reviewed for compatibility with the historic building and the district while infill constriction shall be reviewed for compatibility with the overall district. Neither should directly imitate nor replicate existing features. For additions, every effort should be made to minimize the visibility of the new structure within the district. Infill construction should reflect the character of the district, including the prevailing heights of contributing buildings without creating a false sense of history. Property owners should consult early in the process with a Planning Department Historic Preservation Technical Specialist when developing a proposal.

Additions will be reviewed on a case-by-case basis and any proposed addition should be located in an inconspicuous location and not result in a radical change to the form or character of the historic building. A vertical addition may be approved, depending on how the addition impacts the building and its relative visibility from the surrounding public rights-of-way within the district. The Planning Department evaluates all proposals for properties identified under Article 10 of the Planning Code for compliance with the Secretary of the Interior's Standards (36 C.F.R. § 67.7 (2001)). Based on these Standards, Department staff uses the following criteria when reviewing proposals for vertical additions:

• The structure respects the general size, shape, and scale of the features associated with the property and the district and the structure is connected to the property in a manner that does not alter, change, obscure, damage, or destroy any of the character-defining features of the property and the district.

• The design respects the general historic and architectural characteristics associated with the property and the district without replicating historic styles or elements that will result in creating a false sense of history.

• The materials are compatible with the property or district in general character, color and texture.

As part of the Planning Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the district. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

ing Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the district. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

When a district provides an opportunity for new construction through existing vacant parcels or by replacing noncontributing buildings, a sensitive design is of critical importance. Historic buildings within the district should be utilized and referenced for design context. Contemporary design that respects the District's existing character-defining features without replicating historic designs is encouraged. The Department uses the following criteria when reviewing proposals for infill construction:

• The structure respects the general size, shape, and scale of the character-defining features associated with the district and its relationship to the character-defining features of the immediate neighbors and the district.

• The site plan respects the general site characteristics associated with the district.

• The design respects the general character-defining features associated with the district

• The materials are compatible with the district in general character, color, and texture.

• The only instance where a replication of an original design may be appropriate is the replacement of a missing structure in a row of identical houses.

A district is usually a single geographic area of contiguous historic properties; however, a district may also be composed of multiple definable significant resources separated by non-significant areas. The Market Street Masonry discontiguous district is composed of eight buildings on four blocks that are spatially discrete. The space between the buildings is not related to the significance of the district. While all buildings can be seen from the intersection of Market and Franklin Streets, the visual continuity is not a factor in the significance. Each of the eight discontiguous buildings are contributory to the Market Street Masonry Historic District.

An architectural description, building history and evaluation of each parcel within the Historic District is documented in the Market Street Masonry Historic District Designation Report and are hereby incorporated herein as though fully set forth. It is important to note that street address numbers are subject to change, and that the most reliable, official method for identifying a property within the Landmark District is to refer to it by its assigned Assessor Block and Lot number. (Added by Ord. 64-13, File No. 121004, App. 4/17/2013, Eff. 5/17/2013)

The character-defining features of the Market Street Masonry Historic District include all exterior elevations, including rooflines, of each of the eight buildings. The following section describes in further detail character-defining features of the District and of individual buildings contained therein. Historic District designation is intended to protect and preserve these character-defining features.

(a) Overall Form, Continuity, Scale and Proportion. All buildings are built to the property lines, rise vertically without setbacks, and have flat roofs. Building height is within a three-to-six story range, with one building at three stories, one at four, four at five stories, and two at six stories in height. All buildings in the district retain their historic integrity. The buildings are consistent in height, bulk, scale and proportion.

(b) Fenestration. Existing fenestration consists of predominantly double-hung, wood sash windows that are vertical in orientation; however, industrial steel sash is found, as are awning and casement sash. Buildings feature a symmetrical and regular pattern of windows with consistent dimensions along primary facades. Aside from some ground floor commercial storefronts, the size and shape of window openings have not been altered over time. Replacement window sash that were added to buildings after the period of significance have not gained significance in their own right.

(c) Materials and Finishes. Unpainted brick is the predominant cladding material found in five of the eight buildings in the district; however, painted stucco on concrete is found on three buildings in the district. Galvanized sheet iron is used extensively for decorative features and the cladding of projecting bay windows.

(e) Landscape Elements. All properties in the Historic District are built to their respective lot lines, and do not have landscape features. Streets, sidewalks and other public spaces are present in this dense urban environment, but are incidental, rather than integral to the significance of the buildings. Streets and sidewalks are not included as characterdefining features. Public landscape elements are therefore specifically excluded from this designation.

(f) Additional features of the Historic District are documented in the Market Street Masonry Historic District Designation Report within the section entitled "Common Characteristics of Buildings in the Market Street Masonry District," and are hereby incorporated herein as though fully set forth, and are on file at the Planning Department under Case No. 2011.0705L.

The character-defining interior features of buildings in the district are identified as: None.

The character-defining exterior features of buildings in the district are identified as: All exterior elevations and roof lines as described below.

The character-defining landscape elements of the district are identified as: The rustic interior block park entrances at Carmelita, Pierce, and Potomac Streets – which include the historic stone steps, Serpentine rock retaining walls set in a random rubble pattern, and the public rights-of-way within a 10-foot buffer – and the lack of physical separation between the park and adjacent buildings.

The following section describes in further detail the character-defining features of the district and of individual buildings and landscape elements contained therein. Historic district designation is intended to protect and preserve these characterdefining features.

Due to the brief period of construction – most buildings were constructed between 1899 and 1902 – and combined involvement of two primary builders, buildings within the district exhibit a remarkable consistency in terms of massing, scale, style, detailing, front yard setback, and feeling.

District buildings are overwhelmingly residential, being composed primarily of single-family dwellings and residential flats. A few multiple-family residences within the district (typically located on street corners) also include a commercial use at the street level.

Buildings in the district range from 1½ story-over-basement to four stories in height, with two and three stories predominating. The district's largest single-family residences and flats were built on corner lots directly adjacent to the Park. These buildings are typically two- to three- stories in height and feature consistent detailing on the primary, Parkfacing, and rear façades.

Generally speaking, the buildings fronting Carmelita, Pierce and Potomac Streets were originally constructed as one- or two-family dwellings, while flats dominated the lots facing Waller and Steiner Streets. Mid-block buildings are typically smaller than those constructed at the corners or on Waller and Steiner streets and are more likely to draw from Victorian-

era form and massing such as prominent gabled roof forms and asymmetrical massing at the primary façade. Though consistent in massing, single-family buildings on Potomac Street feature the greatest variety of roof forms, including gable, hipped, cross-gable, and one building with a side gable roof form and small eyebrow dormers.

Buildings located along the interior blocks feature uniform front yard setbacks of approximately nine feet and are often bounded by a low cast stone site wall. The flats buildings on Steiner Street do not feature front yard setbacks; rather, they present a modulated massing of muscular bay windows and deeply recessed entry porticos.

The Queen Anne style buildings present in the district may be subdivided into two basic arrangements: 1½ story-overraised-basement single-family cottages, and 2½ story-over-raised-basement single family dwellings or flats. The buildings tend to conform to a basic plan of a projecting bay on the first floor, flanked by an open porch and entry to the side-with the porch entry often surmounted by spindle work or decorative porch brackets. Roof forms are hipped or steeply pitched front-facing gables. Slightly projecting second story overhangs are common.

Edwardian-era flats building are three stories-over-basement in height with wide projecting structural window bays, featuring angled- or bent-sash windows. The roofline of Edwardian-era flats buildings feature projecting cornices that follow the profiles of the primary façades. The buildings are typically topped with flat roofs, though several feature gable roof forms. Massing is symmetrical, except at the first story, where the two structural bays are occupied by a recessed entrance at one side and a projecting bay window at the other.

ash windows. The roofline of Edwardian-era flats buildings feature projecting cornices that follow the profiles of the primary façades. The buildings are typically topped with flat roofs, though several feature gable roof forms. Massing is symmetrical, except at the first story, where the two structural bays are occupied by a recessed entrance at one side and a projecting bay window at the other.

Original roof projections include turrets topped with witch's cap or conical roof forms and small-scale cross-gables atop projecting bay windows. Turrets, found on both Queen Anne and Edwardian-era buildings, are generally located at the corner, adjacent to or embedded within a forward-facing gable. Additionally, several buildings exhibit what appear to be historic dormers. Located on sloped gables, these dormers are small in scale, gabled, and match the ornamentation and fenestration of primary façades.

Although the roof forms – particularly at the non-visible rear façade – of a substantial number of buildings have been altered to incorporate skylights, small dormer windows, fire escapes, or solar panels, these alterations were constructed outside of the Period of significance and have not gained significance in their own right.

Similar roof forms, massing, and setbacks result in a cohesive streetscape of rooflines, entrances, continuous primary façades, and modulated bays. With no visual separation between buildings in the district, the block faces present an overall appearance of attached row-houses; however, with a few exceptions, it is unlikely that buildings feature shared structural walls.

Fenestration is remarkably consistent throughout the district, consisting of vertically oriented double-hung wood sash windows, with ogee lugs, set in wood surrounds. Windows are typically set in wide angled bays with smaller windows set flush with the façade, often adjacent to the primary entry door. Windows surround are typically topped with cornices, occasionally featuring pediments, with ornamented details.

Smaller vertically oriented windows, set in a single, pair, or ganged configuration, are also often located in the tympanum of the Queen Anne style buildings. Tympanums typically have a higher solid-to-void ratio than the lower stories. Several buildings – typically Edwardian-era flats buildings – feature curved wood sash windows set in curved structural bays. Angled or curved bays typically contain three windows, though certain bays of corner buildings contain four windows. While rare, several buildings display two-sided angled bay windows at the primary façade.

Large corner buildings with greater surface area have a higher solid-to-void ratio than mid-block buildings. Window bays and window openings set flush with the façade are typically placed in the same location, presenting a stacked appearance, at each story of the three story comer buildings.

The vast majority of buildings within the district retain some or all historic double-hung wood sash windows with ogee lugs. Replacement windows made of aluminum or vinyl sash, casement windows, or windows with divided lights that were added to buildings after the Period of significance have not gained significance in their own right. c) Materials & Finishes.

Buildings in the district are of wood frame construction and were historically clad in horizontal wood siding. Exterior surface finishes are painted. Channel drop wood siding is typical at the secondary and rear façades, while a combination of flush, lap, channel drop, and shingles are typically found at the primary façades of Victorian-era buildings. Flush wood siding is most common on the primary façades of Edwardian-era flats buildings. Most buildings retain their historic siding though a few were later clad in stucco, asbestos, or composite shingle siding. These replacement sidings have not gained significance in their own right.

Historically, the gabled roofs within the district were clad in unpainted wood shingles. These historic roofing materials are no longer present. Existing gable roofs are typically finished with asphalt or composite shingles that match the color and tone of the historic wood roofing materials. Though generally compatible, this replacement roofing material has not gained significance in its own right.

Common traits found throughout the district are bay windows, gable roofs, decorative cornices, ornamental shingles, and spindle work, as well as more classically influenced detailing such as dentils, pediments, columns, and applied plaster ornament. Ornamental details are typically larger and more robust in scale at the first story, with finer, more delicate features located at the upper floors.

Many of the district's buildings retain their original primary entrance doors. These paneled wood doors, often slightly wider than contemporary entrance doors, are commonly glazed at the upper portion and feature corniced hoods and incised or applied ornament. Occasionally, a single fixed window is located adjacent to the entry door of Queen Anne buildings and some doors, of both Queen Anne and Edwardian-era buildings, are topped with transom windows.

Late Victorian- and Edwardian-era architectural styles predominate, with the Queen Anne style most widely represented. Though Victorian-era architectural design displayed a remarkable variety of ornament, unifying features include asymmetrical and articulated façades, steep roof pitches, and the use of multiple textures, materials and colors.

Many of the Queen Anne style buildings on Potomac Street, designed by developer George Moore, stand out for their muscular massing, restrained ornament, projecting second story overhangs, and hipped roof forms. In contrast, the developer Fernando Nelson designed most of the Queen Anne buildings on Pierce, Potomac, and Waller streets, to reflect his embrace of more exuberant and delicate architectural features, including spindle screens, turrets, and cut-outs. Architectural details commonly found on Queen Anne buildings throughout the district include raked cornices, flared eaves, shingled tympanums, diamond and fish-scale shingling, turrets (particularly at corner buildings), projecting bracketed cornices, steeply pitched gable roofs, double-gables, finials, geometric applied ornament at spandrel panels, dentils, friezes decorated with plaster ornament, egg and dart molding, cut-out screens, sunbursts, donut cut-outs, intermediate cornices, window and door hoods, spindle screens, turned wood balustrades and newel posts, Tudor-inspired stick work, turned wood porch supports, a variety of wood cladding and patterned wood shingles, arched porticos, and Corinthian or Composite columns and pilasters. Anthropomorphic details are rare but present within the district. Historically, there were several types of stairs constructed in the district: longer flights of wood stairs that typically project out from Queen Anne style buildings and shorter flights typically found within the recessed entries of Edwardianera flats buildings.

The Queen Anne buildings on interior block streets are typically accessed via a straight run flight of wood stairs. Due to the slope, stairs on the west side of these blocks are significantly longer than those on the east. Historically, wood stairs on these interior blocks were solid and uniform in appearance: featured closed risers, solid cheek walls beneath the stairs, turned wood balustrades, and capped newel posts; and had a painted finish. Some flights of stairs were later replaced with brick, concrete, tile, or terrazzo. These replacement stairs have not gained significance in their own right.

Edwardian-era buildings, referred to locally as Classical Revival, were constructed in San Francisco from approximately 1901 to 1910. The term Edwardian is used architecturally to describe a more vernacular interpretation of the Classical Revival style and is commonly applied to three-unit flats buildings – like those found within the district – with wide

angled or round bay windows, flat roofs, bulky projecting cornices, and columned porch entries. Edwardian-era buildings within the district, particularly those on Steiner Street, feature wood or terrazzo steps with solid cheek walls and landings. These stairs are typically located largely within the building envelope and provide access to recessed entrance doors. Entrances of Edwardian-era flats in the district are typically flanked by Classical columns or pilasters, and decorated with applied plaster ornament, such as garlands and floral friezes.

Architectural ornament associated with the Edwardian-era is typically more restrained than those used during the Victorian-era. The turn-of-the-century development of buildings within the district, however, often resulted in a fusion of Edwardian-era massing with exuberant Victorian-era detailing. It is common in the district for Edwardian-era flats to feature unusually ornamented spandrel panels and decorative friezes and several are capped with the gable roof form more commonly associated with Queen Anne style buildings.

Properties within the district typically feature uniform front yard setbacks on each block face. Setbacks on the west side of interior blocks are generally much deeper – typically 13' to 17' – than the east side, which, depending upon the block, range from approximately 5' to 13'. Setbacks on the western portion of Waller Street are uniform on each block face, ranging from approximately 8' to 12'. Despite the variability in front yard depth, each block face features similar setbacks and reads as uniform. Buildings located on the eastern portion of Waller and Steiner streets, typically Edwardian-era flats, are built out to the sidewalk, with no or minimal front yard setbacks.

Historically, front yards were bounded with low cast stone site walls and planted with vegetation. Site walls on Carmelita Street – and possibly other blocks – were originally topped with decorative iron fencing. Despite the west to east downward slope, the yards located within the front setback are level rather than terraced or sloped.

Several sections of site walls on Carmelita Street retain all or a portion of their original decorative iron fencing. Front yard setbacks and remnants of intact cast stone site walls are also located along Waller, Pierce, and Potomac Streets. The addition of garages has altered the front yards of many district properties. None of the historic buildings within the district were originally constructed with an integrated or detached automobile garage. On most blocks, portions of site walls were removed and front yards partially paved in order to accommodate driveways for garages inserted in the basement of many buildings. Several properties feature detached or semi-attached pop-out garages in the front yard. Garage structures, openings, and driveways are not considered significant in their own right.

The development history of residential properties within the Duboce Park Historic District is closely intertwined with the history of the adjacent Duboce Park. Certain identified elements on the periphery of Duboce Park reflect this close association between residential and park development; notably, the lack of a physical separation between residential buildings and the park and rustic entrances from cul-de-sac streets into the park. These park entrances – located at the foot of Potomac Street, Pierce Street, and Carmelita Street – feature rustic stone steps flanked by low retaining walls built of Serpentine rock set in a random rubble pattern.

For the purpose of Article 10 , the park entrances at Potomac Street, Pierce Street, and Carmelita Street are defined as the steps, rock walls, and a surrounding 10-foot buffer. The buffer area includes the sidewalks, street rights-of-way and area within the park directly adjacent to the steps and rock walls.

(Added by Ord. 107-13 , File No. 130070, App. 6/13/2013, Eff. 7/13/2013)

For the purpose of this Appendix N only, the following terms shall have the following meanings:

Interior Block Park Entrance: The interior block park entrances at Potomac Street, Pierce Street, and Carmelita Streets are defined as the steps, Serpentine rock retaining walls, and a surrounding 10-foot buffer. The buffer area includes the sidewalks, street right-of-way and area within the park directly adjacent to the steps and rock retaining walls.

Primary Façade: A primary façade is a building's main street-racing façade. Corner buildings have two primary façades; the second primary façade may front Duboce Park or the street.

Rear Façade: The rear façade is located at the rear of the building.

Public Right-of-Way: A public right-of-way is a street, sidewalk, interior block park entrance, or park. Visibility: A building, feature, or alteration is considered "visible" when it can be seen from a public right-of-way within the District and/or is visible from Duboce Park. Visibility from Duboce Park is limited to the highly visible façades of the first three buildings adjacent to the Park. Due to their distance from the Park, the rear façades of buildings adjacent to the western portion of Duboce Park (parallel to Scott Street) are excluded from this definition of visibility. See map.

SEC. 5. STATEMENT OF SIGNIFICANCE.

The Clyde and Crooks Warehouse District is significant as it is representative of the post-1906 San Francisco earthquake and fire reconstruction period and is representative of warehouse/industrial building type and exemplifies early twentiethcentury methods of construction and materials. The period of significance is 1906 to 1935. The district is comprised of nineteen properties, twelve of which include contributing resources, located in the South of Market neighborhood. The non-contributing properties consist of two buildings constructed after the period of significance and five surface parking lots.

The Clyde and Crooks Warehouse District’s period of significance reflects the nineteenth-century development of the South of Market area as a center of industrial production in San Francisco and maritime commerce along the west coast. The district’s mix of industrial and warehouse buildings interspersed with residential structures is typical of the land use patterns developed in the nineteenth century in the South of Market neighborhood and continued during the 1906 earthquake and fire reconstruction period. The buildings exemplify early twentieth-century methods of construction and materials and reconstruction the return of South of Market’s function as the industrial center of the city following the earthquake and fire.

is typical of the land use patterns developed in the nineteenth century in the South of Market neighborhood and continued during the 1906 earthquake and fire reconstruction period. The buildings exemplify early twentieth-century methods of construction and materials and reconstruction the return of South of Market’s function as the industrial center of the city following the earthquake and fire.

The addition’s period of significance, 1906-1935, falls within the broader 1867-1935 period of significance of the South End Historic District. The industrial buildings found within the Clyde and Crooks Warehouse District are unique for their smaller size and massing, reflecting their use as small manufacturing operations and storage and packing facilities, but are consistent with the character and development pattern of the buildings constructed in the area during the post-earthquake period. The buildings reflect the redevelopment pattern of South of Market following the quake and fire, which largely consisted of industrial and warehouse buildings.

(Added by Ord. 256-18, File No. 180723, App. 11/2/2018, Eff. 12/3/2018)

Twelve buildings within the boundaries of the Clyde and Crooks Warehouse District are identified as contributory buildings that date from the Historic District’s period of significance and retain their historic integrity. These structures are of the highest importance in maintaining the character of the Historic District. An architectural description, building history and evaluation of each parcel within the Historic District is documented on the State of California – Department of Parks and Recreation Primary Record (DPR 523A – descriptive) survey forms.

The following buildings are deemed Contributory to the Historic District:

Noncontributory. This category identifies buildings which postdate the Historic District’s period of significance and/or no longer retain sufficient integrity to convey significance. Alterations to Noncontributory buildings would require Certificate of Appropriateness review in order to ensure that alterations and new construction would be compatible with the historic character of the District in terms of scale, massing, fenestration, materials and detail outlined in this appendix and the applicable standards for review pursuant to Article 10 of the Planning Code.

The following buildings shall be deemed to be Noncontributory within the Historic District:

(Added by Ord. 256-18, File No. 180723, App. 11/2/2018, Eff. 12/3/2018)

The following section describes in further detail the character-defining features of the District and of individual buildings contained therein. Historic District designation is intended to protect and preserve these character-defining features.

a.¹ Overall Form, Continuity, Scale and Proportion. All buildings are built to the property lines and rise vertically without setbacks. Building heights are two to three stories, with the exception of the one-story building at 45 Lusk Street. Ten of the twelve contributing buildings have flat roofs. One building (435 Brannan) has a combination gable and flat roof. One building (322-326 Ritch Street) has a double-gable roof. The District’s buildings are rectangular plan and largely masonry structures with the exception of four wood frame buildings.

CODIFICATION NOTE

1. So in Ord. 256-18.

The standards for review of all applications for Certificates of Appropriateness are as set forth in Section 1006.6 of Article 10. For the purposes of review under those standards, the “character of the Historic District” shall mean the exterior architectural features of the Clyde and Crooks Warehouse District referred to and described in Section 6 of this Appendix.

Any exterior change within the Clyde and Crooks Warehouse District shall require a Certificate of Appropriateness, pursuant to the provisions of Article 10, when such work requires a City permit, with the exception of specific scopes of work identified by the Historic Preservation Commission and delegated to Planning Department Preservation staff for review and approval and specific scopes of work as outlined below. The procedures, requirements, controls and standards of Article 10 of the Planning Code shall apply to all applications for Certificates of Appropriateness and/or Administrative Certificates of Appropriateness in the Clyde and Crooks Warehouse District. (Added by Ord. 256-18, File No. 180723, App. 11/2/2018, Eff. 12/3/2018)

Additions to existing buildings and new infill construction proposed within the Clyde and Crooks Warehouse District must reflect an understanding of the relationship of the proposal with the contributing buildings within the district. Additions shall be reviewed for compatibility with the historic building and the District, while infill construction shall be reviewed for compatibility with the overall District. Neither should directly imitate nor replicate existing features. For additions, every effort should be made to minimize the visibility of the new structure within the District. Infill construction should reflect the character of the District, including the prevailing heights of contributing buildings without creating a false sense of history. Property owners should consult early in the process with a Planning Department Historic Preservation staff when developing a proposal.

(a) Additions. Additions shall be reviewed on a case-by-case basis and any proposed addition should be located in an inconspicuous location and not result in a radical change to the form or character of the historic building. A vertical addition may be approved, depending on how the addition impacts the building and its relative visibility from the surrounding public rights-of-way within the district. The Planning Department evaluates all proposals for properties identified under Article 10 of the Planning Code for compliance with the Secretary of the Interior’s Standards (as set forth in Section 1006.6 of the Planning Code). Based on these Standards, Department staff uses the following criteria when reviewing proposals for vertical additions:

(1) The structure respects the general size, shape, and scale of the features associated with the property and the District and the structure is connected to the property in a manner that does not alter, change, obscure, damage, or destroy any of the character-defining features of the property and the District.

(2) The design respects the general historic and architectural characteristics associated with the property and the District without replicating historic styles or elements that will result in creating a false sense of history.

(3) The materials are compatible with the property or District in general character, color and texture.

As part of the Planning Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the District. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

ing Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the District. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

(b) New Construction. When a district provides an opportunity for new construction through existing vacant parcels or by replacing non-contributing buildings, a sensitive design is of critical importance. Historic buildings within the District should be utilized and referenced for design context. Contemporary design that respects the District’s existing characterdefining features without replicating historic designs is encouraged. The Department uses the following criteria when reviewing proposals for infill construction as well as the review standards set forth in Section 1006.6 of the Planning Code:

(1) The structure respects the general size, shape, and scale of the character-defining features associated with the district and its relationship to the character-defining features of the immediate neighbors and the district.

• (2) The site plan respects the general site characteristics associated with the district.

• (3) The design respects the general character-defining features associated with the district.

• (4) The materials are compatible with the district in general character, color, and texture.

(1) Facade Line Continuity. Facade line continuity is historically appropriate. Therefore, setbacks at lower floors and arcades, not generally being features of the Clyde and Crooks Warehouse District, are generally not acceptable.

(2) Fenestration and Design Elements for New Construction. In areas with a concentration of buildings characterized by a high proportion of mass to void and deeply recessed openings, vertical orientation and limited fenestration, the design of new construction should relate to those elements. In areas characterized by buildings with industrial style fenestration, new construction should relate to those design elements.

(d) Exterior Changes Requiring Approval. Any exterior change within the Clyde and Crooks Warehouse District shall require a Certificate of Appropriateness pursuant to the provisions of Article 10 when such work requires a city permit. In addition, a Certificate of Appropriateness shall be required for cleaning masonry surfaces with abrasives and/or treatment of such surfaces with waterproofing chemicals. Sandblasting and certain chemical treatments detrimental to older brick will not be approved.

• (e) Signs.

(1) Principal Signs. Only one sign will be allowed per establishment per street frontage. A flush sign with lettering intended to be read from across the street is permitted. On brick surfaces, signs should be mounted with a minimum number of penetrations of the wall, and those penetrations only in the mortar joints.

(2) Secondary Signs. One per establishment per street frontage. A secondary sign is intended to be viewed close-up and consists of: (A) lettering on a door or window that contains only the name and nature of the establishment, hours of operation and other pertinent information; or (B) a projecting sign not exceeding two square feet in area used in conjunction with a principal flush sign.

(f) Nothing in this legislation shall be construed to regulate paint colors within the District.

(Added by Ord. 256-18, File No. 180723, App. 11/2/2018, Eff. 12/3/2018; amended by Ord. 136-21, File No. 210674, App. 8/4/2021, Eff. 9/4/2021)

AMENDMENT HISTORY

Division (e)(2) amended; final division redesignated as (f); Ord. 136-21, Eff. 9/4/2021.

Whenever a building, district, site, object, or landscape is under consideration for Article 10 Landmark designation, the Historic Preservation Commission is required to identify character-defining features. This is done to enable owners and the public to understand which elements are considered most important to preserve the historical and architectural character of the proposed landmark or landmark district.

The character-defining interior features of buildings in the district are identified as: None.

The character-defining exterior features of contributory buildings in the district are identified as: All exterior elevations, rooflines, historic doors and fenestration, historic materials and finishes, historic front setbacks, and historic architectural details, as described below.

The following section describes in further detail the character-defining features of the district and of individual buildings.

A. Overall Form, Scale and Proportion

Due to the brief period of construction – most contributory buildings were constructed between 1865 and 1905 – buildings within the district exhibit characteristics of one of two basic residential property types: single-family early residential or multi-family reconstruction residential (as defined in the Mission Dolores Context Statement). District buildings are almost all residential, composed primarily of detached, attached or semi-attached, single-family dwellings and residential flats or apartments. A couple of mixed-use buildings within the district (typically located on street corners) with residences on upper floors also include commercial use at the street level. Buildings in the district range from 1 ½ story-over-basement to four stories in height, with 1 ½ and three stories predominating. Roof forms are predominantly flat, front-facing gable, or front-facing gable behind a projecting parapet and/or cornice. Several buildings have hipped roofs.

The district’s smallest residences are on lots facing the neighborhood’s alleys and narrow mid-block streets. These buildings are typically 1 ½- to two-stories in height, have raised, recessed entrances accessed by straight-run wood staircases with turned balustrades, often have deep front setbacks, and feature Folk Victorian, modest Italianate or StickEastlake detailing on the primary, street-facing facades. Folk Victorian style buildings are often adorned with basic decorative elements such as spindle work porches. Some of these smaller buildings have been converted from single- to two-units.

Buildings fronting wider streets – 17th and Dolores streets – have larger footprints, are taller, and consist of residential flats or apartments. These buildings are typically 2 ½- to four-stories in height, have recessed, raised entrances, straight run stairs, and feature Queen Anne, Classical Revival, Italianate, or Stick-Eastlake detailing on the primary, street-facing facades. Romeo Flats buildings at Dolores Street are built to the front lot line while residential flats buildings at 17th Street are often setback with front yards.

nts. These buildings are typically 2 ½- to four-stories in height, have recessed, raised entrances, straight run stairs, and feature Queen Anne, Classical Revival, Italianate, or Stick-Eastlake detailing on the primary, street-facing facades. Romeo Flats buildings at Dolores Street are built to the front lot line while residential flats buildings at 17th Street are often setback with front yards.

Although the roof forms – particularly at the non-visible rear facade – of a substantial number of buildings have been altered to incorporate skylights, small dormer windows, fire escapes, stair penthouses, or solar panels these alterations were constructed outside of the Period of Significance and have not gained significance.

General characteristics of the district’s two primary residential building types (Single-Family Early Residential and Multi-Family Reconstruction Residential) and one sub-type (Romeo Flats) are:

Single-Family Early Residential: Properties dating from the “Early Neighborhood Development (1864-1906)” period are unified by their common forms, massing, and materiality representative of the early residential and agricultural development of the Mission Dolores neighborhood. Character-defining features of the properties within the district dating from this period include:

• Small, one-story over- integrated garage or two-story massing

• Horizontal painted wood siding

• Front-facing gable roof, Italianate style flat-front parapet roof form, or projecting bracketed cornices

• Wood double-hung windows with ogee lugs

• Architectural ornament including brackets, applied columns, window and/or door hoods, and other façade ornamentation indicative of the various architectural styles

• Front setback or location on lot in reference to street

• Central or offset primary entrance and stair

Multi-Family Reconstruction Residential: Properties dating from the “Earthquake and Reconstruction (1906-1915)”

period are unified by their larger scale, form, and massing to meet housing needs of the growing population of the Mission Dolores neighborhood. Character-defining features of the residential flats or apartment buildings within the district dating from this period include:

• Two or three-story over-integrated garage or three-story massing

• Horizontal painted wood siding

• Front-facing gable roof or projecting cornice

• Wood double-hung windows with ogee lugs

• Single or paired projecting bay(s) at front facade

• Front setback/location on lot in reference to street

• Offset entrance with recessed, straight-run original stair configuration

Romeo Flats: The Romeo flat, a San Francisco-based, high-density form of rental housing with four to six units, generally for working-class tenants, was typically built after the 1906 earthquake and fires. Romeo flats are multi-unit, residential buildings with three bays lining the façade. An open or enclosed, central winding staircase located in the central bay divides the façade vertically. Balconies are located at each story of the central bay if it is open. When enclosed, windows are located at each landing. Several district buildings along Dolores Street are Romeo Flats. B. Materials and Finishes

Buildings in the district are of wood frame construction and were historically clad in horizontal wood siding. Exterior surface finishes are painted. Channel drop wood siding is typical at the secondary and rear facades, while a combination of flush lap, channel drop, clapboard, or shaped shingles are typically found at the primary facades. Most buildings retain their historic siding though a few were later clad in stucco, masonite, or composite shingle siding. These replacement siding materials have not gained significance.

Historically, there were several types of stairs constructed in the district: longer flights of wood stairs that typically project out from Italianate or Stick-Eastlake style buildings and shorter flights typically found within the recessed entries of Progressive-era flats and apartment buildings. Many of the Folk Victorian residences have wood porches with spindlework details at the ground level entrances.

At the buildings along alleys and narrow streets, entry stairs are often solid and uniform in appearance featuring closed risers, solid cheek walls beneath the stairs, turned wood balustrades, and capped newel posts, and have a painted finish. Some flights of stairs were later replaced with new wood stairs and balusters. Raised entrances to these smaller residential buildings lead to narrow openings highlighted with wood trim and bracketed hoods. Wood paneled and glazed doors with transom window sit within a shallow paneled recess.

Progressive-era buildings – Queen Anne or Classical Revival style – within the district, particularly those on 17th and Dolores streets, feature wood or terrazzo steps with solid cheek walls and landings. These stairs are typically located partially within the building envelope and provide access to recessed entrance doors. The recessed vestibules have wood paneled walls, coffered or stucco-clad ceilings, and floors clad in wood, terrazzo, or tile (usually hexagonal tiles with a polychromatic trim or mosaic tile). Entrances of Progressive-era flats are typically flanked by Classical columns or pilasters, and decorated with applied plaster ornament, such as garlands and floral friezes.

While compatible, replacement stairs have not gained significance in their own right.

Existing gable roofs are typically finished with asphalt or composite shingles. Though generally compatible, these roofing materials have not gained significance.

C. Doors and Fenestration

Many of the district’s buildings retain their original primary entrance doors. These paneled wood doors, often slightly wider than contemporary entrance doors, are commonly glazed at the upper portion and feature corniced and bracketed hoods and incised or applied ornament. Occasionally, a single fixed window is located adjacent to the entry door of Queen Anne buildings, and many entry doors are topped with transom windows.

Fenestration is remarkably consistent throughout the district, consisting of vertically oriented double-hung single-light wood sash windows, with ogee lugs, set in wood surrounds. Windows are typically set in wide angled bays with smaller windows set flush with the facade, often adjacent to or above the primary entry. Window surrounds are typically topped with cornices, occasionally featuring pediments, with ornamented details. Smaller vertically oriented windows, set in a single or paired configuration, are typical on Italianate buildings. Some windows have segmental-arched upper sash. Several buildings, typically Progressive-era flats buildings, feature curved wood sash windows set in curved structural bays. Angled or curved bays typically contain three windows, though certain bays of corner buildings contain four or five windows. Most windows are rectangular although there are several buildings with arched windows.

Large flats buildings, particularly Romeo flats, have continuous stacked angled bays flanking enclosed central stair with flush window at each landing.

On visible side and rear elevations, windows are typically single or paired double-hung sash with simple wood surrounds.

While many buildings within the district retain some or all historic double-hung wood sash windows with ogee lugs on primary, street-facing elevations, many others have replacement sash. Replacement windows made of aluminum or vinyl sash, casement or slider windows, or windows with divided lights that were added to buildings after the Period of Significance have not gained significance.

The addition of garages has altered the front facades and yards of many District properties. Many of the historic buildings within the district were not originally constructed with an integrated automobile garage. Many front yards have been fully or partially paved to accommodate driveways for garages inserted in the basement of many buildings. Garage structures, openings, and driveways have not gained significance.

Several corner buildings have ground floor commercial spaces that are characterized by glazed entry doors set in recessed vestibules with large, fixed storefront windows on solid raised bulkheads. Transom windows span the storefronts.

D. Architectural Details

Common traits found throughout the district are bay windows, gable roofs, parapets, decorative cornices, ornamental shingles, and spindle work, as well as more classically influenced detailing such as dentils, pediments, columns, and applied plaster ornament.

Late Victorian- and Progressive-era architectural styles predominate with Italianate, Stick-Eastlake, Queen Anne, and Classical Revival styles most widely represented. Architectural details commonly found on the district’s Italianate and Stick-Eastlake buildings – usually at the smaller dwellings on alleys and narrow streets – include cornice lintels, bracketed hoods, raised panel friezes and bracketed cornices, and false shaped parapets sometimes with pent roofs for Italianates (3639 17th Street features a canted bay window with colonette mullions and an elaborate cornice at each story) and bracketed cornice caps, elaborate bracketed door hoods (flat or pedimented) and trim, false parapets with paneled friezes, brackets, raised porches with spindlework frieze and turned wood supports, and projecting cornices on Stick-Eastlakes (3656 17th Street chamfered bay window features mullions with engaged colonettes and paneled aprons, while a cornice defines its first story windows; 3620-3624 17th Street features a box bay capped with a tall, false pedimented gable with sunburst inlay).

Folk Victorian buildings were most often simple working-class residences, or modest vernacular buildings that were adorned with basic decorative elements such as spindle work porches or cornice-line brackets

The district’s larger flats buildings, facing onto the wider, primary streets, are typically Classical Revival style, including all the district’s Romeo Flats buildings. Buildings in the district in this style feature wide angled or round bay windows, flat roofs, bulky projecting cornices with modillions or dentils, raised panel spandrels, scroll keystones, broken entablatures, and pedimented and columned porch or portico entries.

Architectural details commonly found on Queen Anne buildings in the district include raked cornices, flared eaves, shingled tympanums, fish-scale shingling, projecting bracketed cornices, steeply pitched gable roofs, finials, geometric applied ornament at spandrel panels, dentils, friezes decorated with wood ornament, egg and dart molding, cut-out screens, sunbursts, intermediate cornices, window and door hoods, spindle screens, turned wood balustrades and newel posts, turned wood porch supports, a variety of wood cladding and patterned wood shingles, arched porticos, and Corinthian or Composite columns and pilasters.

Visibility: Visible from within a 150-foot radius of the parcel boundaries. Visibility from a public right-of-way can be determined by drawing circles with a radius of 150 feet at each corner of a lot that fronts on a public right-of-way and then determining which portions of a property are visible when standing in the public right-of-way. Public Right-of-Way: A public right-of-way is a street or sidewalk.

Primary Façade or Elevation: A primary façade is a building’s main street-facing façade. Corner buildings have two primary façades.

Rear Façade or Elevation: The rear façade is located at the rear of the building and faces the backyard. (Added by Ord. 14-26, File No. 251100, App. 2/13/2026, Eff. 3/16/2026)

The standards for review of all applications for Certificates of Appropriateness are as set forth in Section 1006.6 of Article 10. For the purposes of review under those standards, the “character of the Historic District” shall mean the exterior architectural features of the Chula-Abbey Early Residential District referred to and described in Section 6 of this Appendix.

The three levels of review are: “No Certificate of Appropriateness” is required; an “Administrative Certificate of Appropriateness” is required, which is approved administratively by Planning Department Preservation staff as delegated pursuant to Section 1006.2(b) of the Planning Code; and “Certificate of Appropriateness” is required pursuant to Section 1006 of the Planning Code at a regularly scheduled Historic Preservation Commission hearing. The procedures, requirements, controls and standards of Article 10 of the Planning Code shall apply to all applications for Certificates of Appropriateness and/or Administrative Certificates of Appropriateness in the Chula-Abbey Early Residential District.

Any exterior change within the Chula-Abbey Early Residential District shall require a Certificate of Appropriateness, pursuant to the provisions of Article 10, when such work requires a City permit, with the exception of: scopes of work outlined in Section 1005(e)(1-10) of Article 10; projects subject to the Housing Accountability Act (HAA) that comply with the Preservation Design Standards; and, the specific scopes of work as outlined below.

No Certificate of Appropriateness shall be required for the construction of any structure within the rear yard that is no more than ten feet in height above grade and covers no more than 120 square feet of land regardless of visibility from public rights-of-way. A Certificate of Appropriateness shall not be required for the removal of any non-historic ancillary structure within the rear yard.

Replacement garage doors must have a solid, painted finish and may feature no more than 25 percent glazing.

Tradesman Doors: No Certificate of Appropriateness shall be required for replacement of tradesman doors provided the new tradesman door is compatible with the building and District to minimize visual impacts on the character-defining features of the building and District.

No Certificate of Appropriateness shall be required for the removal of non-historic material to conduct investigation about the historic structure and to determine the existence of underlying historic materials, ghosting, and scarring. This scope of work shall be limited, at the Department’s discretion, to no more than 15% of the total surface area of the façade. This work area must be stabilized and protected after the investigation is complete.

A Certificate of Appropriateness shall not be required for the construction or replacement of rear or side yard fences. Ground Disturbance

Most properties within the Chula-Abbey Early Residential District are also located within the Planning Department’s Archaeological Sensitivity Zone 1 (areas that have high sensitivity for archaeological resources that are at or just beneath the current ground surface). No Certificate of Appropriateness shall be required for any project where ground disturbance is not: 2 feet or deeper (depth below existing street elevation), and more than 25 cubic yards.

Where a project exceeds the ground disturbance criteria of Zone 1, no Certificate of Appropriateness shall be required where Planning Department cultural resources staff, after initial review, determines that the proposed development project is unlikely to result in damage or destruction of significant archaeological resources.

No Certificate of Appropriateness shall be required for any exterior change on elevations not visible from the public rights-of-way for non-contributory properties.

No Certificate of Appropriateness shall be required for any alteration or replacement of exterior building features on visible elevations of non-contributory properties, provided that reasonable efforts shall be made to produce compatibility with the District, and in no event shall there be a greater deviation from compatibility. The Planning Department will evaluate these proposals for compatibility with the character of the historic district as described in the designating ordinance, as set forth in Section 1006.6 of the Planning Code.

A Certificate of Appropriateness shall not be required for projects involving additions and modifications of district buildings that are also subject to the Housing Accountability Act (HAA), provided they comply with the adopted objective design standards outlined in the Preservation Design Standards.

Ordinary Maintenance and Repairs

No Certificate of Appropriateness shall be required if the proposed work consists of ordinary maintenance and repairs, as defined in Section 1005 (e)(3) of the Planning Code as any work, the sole purpose and effect of which is to correct deterioration, decay or damage of existing materials, including repair of damage caused by fire or other disaster.

A Certificate of Appropriateness shall not be required for the in-kind replacement of character-defining features that are deteriorated beyond repair, including historic architectural details such as porticos, porches, cornices, stringcourses,

plaster work, tympanum, roofline, and eaves) regardless of visibility from the public right-or-way.¹ For this standard, “in kind” shall mean repair or replace exactly to match the feature’s material, dimensions, finish, profile, and details. Use of alternative material(s) does not qualify as “in-kind.”

No Certificate of Appropriateness shall be required for roof repair or replacement provided the proposed roof work does not change the roof character, form, structure, or character-defining features. New roofing shall be compatible with existing roofing.

No Certificate of Appropriateness shall be required for repair and/or replacement of roofing materials other than visible surface materials, including but not limited to underlayment, structural members, chimneys, gutters, and scuppers,

that does not alter the existing roof’s form or character-defining features.

1. So in Ord. 14-26.

Excluding the exceptions defined in this Appendix.¹ any exterior change to a contributory or non-contributory building or new construction within the Chula-Abbey Early Residential District shall require a Certificate of Appropriateness, pursuant to the provisions of Article 10, when such work requires a City permit. The following standards shall guide the approval of exterior alterations, additions, and new construction.

(a) Character of the district. New construction shall complement and support the historic character of the district. Proposals for exterior alterations that result in greater conformity with the character of the district and are based on physical or documented evidence are encouraged.

(b) Historic Materials. Exterior alterations or new construction shall not destroy historic materials.¹ features and spatial relationships that characterize the property. Repair and retention of historic windows is encouraged.

(c) Compatibility. New construction shall be differentiated from the old and shall be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment. Additions shall be reviewed for compatibility with the historic building and the District, while infill construction shall be reviewed for compatibility with the overall District. Neither should imitate nor replicate existing features. Additions should not physically or visually dominate existing buildings in the District. Infill construction should reflect the character of the District, including the prevailing heights of contributing buildings without creating a false sense of history. The following standards shall guide the approval of additions and new construction:

Additions. Horizontal and vertical additions on contributing and non-contributing buildings, as well as addition of new features such as garages or window openings in visible elevations of contributing buildings, shall be reviewed on a case-by-case basis. Proposed additions should be located in an inconspicuous location and not result in a radical change to the form or character of the historic building or surrounding District. Due to their diminutive scale and the setbacks of many of the contributory buildings along the narrow alleys and side streets in the District, vertical additions to the contributory buildings facing Chula Lane and Abbey Street are generally discouraged unless it is can be demonstrated that the addition does not impair the form or character-defining features of the building, and that it is not visible from the surrounding public rights-of-way within the District.

As part of the Planning Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the District. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

ing Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the District. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

The Planning Department will evaluate these proposals for compliance with the Secretary of the Interior’s Standards (as set forth in Section 1006.6 of the Planning Code), and, may, at their discretion, refer to the Site Design/Architecture standards of the Preservation Design Standards (adopted by Historic Preservation Commission).

New Construction. Where the District provides an opportunity for new construction through existing vacant parcels or by replacing non-contributing buildings, a sensitive design is of critical importance. The new construction shall respect the general size, shape, and scale of the character-defining features associated with the district and its relationship to the character-defining features of the immediate neighbors and the district. Contributory buildings within the District should be utilized and referenced for design context. For new construction, contemporary design that respects the District’s existing character-defining features without replicating historic designs is encouraged. The Planning Department will evaluate these proposals for compatibility with the character of the historic district as described in the designating ordinance, as set forth in Section 1006.6 of the Planning Code, and, when applicable, the Citywide Design Standards. The following standards shall guide the approval of exterior alterations and new construction:

1. Style. New construction shall be compatible with the character-defining features of the district, yet is contemporary in design.

2. Scale and Proportion. New construction shall be compatible with the massing, size, and scale of the adjacent contributing buildings within the district.

3. Setbacks. New construction shall conform to existing setback patterns found in adjacent buildings and within the district.

4. Roofline. Gabled, cross-gabled, or hipped roof forms or flat roofs with projecting cornices are common within the district and new construction shall reference the massing and form of adjacent buildings.

5. Dormers and Additions. The enlargement or construction of dormers, penthouses and horizontal or vertical additions shall be designed in a manner that requires minimal change to the character-defining features of the subject building and the district in terms of materials, fenestration, cladding, massing and ornamentation.

6. Garages. The insertion of a garage shall minimize the physical and visual impacts on the character-defining features of the existing building and front yard setting. The design of garages and garage doors shall be unobtrusive and simple. Painted roll-up doors with panels and minimal glazing are encouraged.

7. Driveways and Front Yard Setbacks. The addition of new driveways shall minimize the removal of landscaping and include permeable paving materials in order to minimize disruption to front yard setbacks and the character-defining features of the subject building and the district.

8. Details. Architectural details on new construction shall be contemporary, yet compatible with the characterdefining features found on the contributing buildings within the district. (Added by Ord. 14-26, File No. 251100, App. 2/13/2026, Eff. 3/16/2026) CODIFICATION NOTE

(Added by Ord. 15-26, File No. 251101, App. 2/13/2026, Eff. 3/16/2026)

SEC. 5. STATEMENT OF SIGNIFICANCE.

Identified through the Mission Dolores Neighborhood Context Statement & Survey, the Alert Alley Early Residential District is a one-block long stretch of properties, centered on Alert Alley and Landers Street, significant as a representative collection of Italianate, Classical Revival, and Queen Anne residential buildings associated with the themes of “Early Neighborhood Development (1864-1906)” and “1906 Earthquake and Reconstruction (1906-1915).” The period of significance is 1890 to 1910. The District is comprised of 21 properties, eighteen of which include contributing resources, located in the Mission Dolores neighborhood. There are three non-contributing properties.

The Alert Alley Early Residential District is significant as a representative collection of residential buildings that physically illustrate the neighborhood’s pre- and post-1906 Earthquake and Fires development transition. Because it was spared from the 1906 fires that decimated many other nearby neighborhoods, the district provides a unique combination of early, small scale single-family homes along with post-1906 reconstruction era larger scale multi-family flats and apartments. The Alert Alley Early Residential District is a collection of buildings that represents the early small-scale residential and agricultural development patterns of the Mission Dolores neighborhood as well as larger residential flats and apartments indicative of the post-1906 reconstruction period. The district is also notable as it contains several buildings, including 260-264 and 266-268 Dolores Street, associated with the Dolores Street Fire Line, which served as a firebreak preserving properties west of Dolores from destruction in the devastating post-earthquake fires.

ores neighborhood as well as larger residential flats and apartments indicative of the post-1906 reconstruction period. The district is also notable as it contains several buildings, including 260-264 and 266-268 Dolores Street, associated with the Dolores Street Fire Line, which served as a firebreak preserving properties west of Dolores from destruction in the devastating post-earthquake fires.

The Alert Alley Early Residential District also is architecturally significant as a distinctive grouping of Victorian-era residential dwellings in Italianate, Stick-Eastlake, and Queen Anne styles. Along the narrow alleys, the pioneer origins of the buildings are indicated via setbacks, small building footprints, and low-slung massing, which stand out amongst the many larger rowhouses and flats that comprise much of the rest of the urbanized neighborhood. In the post-earthquake period, the Mission Dolores neighborhood transitioned from a semi-suburban, single-family dwelling area at the periphery of the city, to a dense neighborhood fully integrated into the larger urban context, characterized by an increase in multifamily development, particularly with the construction of apartment buildings and flats, including “Romeo Flats,” in Classical Revival and Queen Anne architectural styles.

The period of significance for the District is 1890 to 1910, inclusive of the period of construction of all contributing buildings within the District. Additional historic information, and descriptions of individual buildings, may be found in the Alert Alley Early Residential District Designation Report, which is hereby incorporated herein as though fully set forth. (Added by Ord. 15-26, File No. 251101, App. 2/13/2026, Eff. 3/16/2026)

SEC. 6. CHARACTER-DEFINING FEATURES.

Whenever a building, district, site, object, or landscape is under consideration for Article 10 Landmark designation, the Historic Preservation Commission is required to identify character-defining features. This is done to enable owners and the public to understand which elements are considered most important to preserve the historical and architectural character of the proposed landmark or landmark district.

The character-defining interior features of buildings in the district are identified as: None.

The character-defining exterior features of contributory buildings in the district are identified as: All exterior elevations, rooflines, historic doors and fenestration, historic materials and finishes, historic front setbacks, and historic architectural details, as described below.

The following section describes in further detail the character-defining features of the district and of individual buildings.

A. Overall Form, Scale and Proportion

Due to the brief period of construction – most buildings were constructed between 1890 and 1910 – buildings within the district exhibit characteristics of one of two basic residential property types: single-family early residential or multi-family reconstruction residential (as defined in the Mission Dolores Neighborhood Context Statement).

District buildings are all residential, composed primarily of attached or semi-attached, single-family dwellings and residential flats or apartments. Buildings in the district range from 1 ½ story-over-basement to four stories in height, with 1-½ and three stories predominating. Roof forms are predominantly flat or front-facing gable behind a projecting parapet and/or cornice. An exception is 1919-1923 15th Street which has a hipped roof.

The district’s smallest residences are on lots facing the neighborhood’s alleys and narrow mid-block streets. These buildings are typically 1 ½- to two-stories in height, have raised, recessed entrances accessed by wood staircases with turned balustrades (most stairs have dogleg configurations, replacing original straight run), often have deep front setbacks, and feature modest Italianate or Stick-Eastlake detailing on the primary, street-facing facades. Some of these smaller buildings have been converted from single- to two-units.

Buildings fronting wider streets – 15th, 16th, or Dolores streets – have larger footprints, are taller, and consist of residential flats or apartments. These buildings are typically 2 ½- to four-stories in height, have recessed, raised entrances, straight run stairs, and feature Queen Anne, Classical Revival, Italianate, or Stick-Eastlake detailing on the primary, streetfacing facades. Romeo Flats buildings along 15th Street are built to the front lot line while residential flats buildings at 16th Street are setback with shallow front yards behind low cast stone walls topped with metal railings. On Dolores Street, residential flats buildings are setback with raised front yards bounded by cast stone retaining walls.

Although the roof forms – particularly at the non-visible rear facade – of a substantial number of buildings have been altered to incorporate skylights, small dormer windows, fire escapes, stair penthouses, or solar panels these alterations were constructed outside of the Period of Significance and have not gained significance.

General characteristics of the district’s two primary residential building types (Single-Family Early Residential and Multi-Family Reconstruction Residential) and one sub-type (Romeo Flats) are:

Single-Family Early Residential: Properties dating from the "Early Neighborhood Development (1864-1906)" period are unified by their small-scale form, massing, and materiality representative of the early residential and agricultural development of the Mission Dolores neighborhood. Character-defining features of the properties within the district dating from this period include:

• Small, one-story over- integrated garage or two-story massing

• Horizontal painted wood siding

• Flat front with front facing gable roof or Italianate style parapet roof form

• Original wood double-hung windows with ogee lugs

• Architectural ornament including brackets, applied columns, window and/or door hoods, and other façade ornamentation indicative of the Italianate style

• Front setback or location on lot in reference to street

• Central or offset primary entrance stair

Multi-Family Reconstruction Residential: Properties dating from the “Earthquake and Reconstruction (1906-1915)” period are unified by their larger scale, form, and massing to meet housing needs of the growing population of the Mission Dolores neighborhood. Character-defining features of the residential flats or apartment buildings within the district dating from this period include:

• Two or three-story over-integrated garage or three-story massing

• Horizontal painted wood siding

• Front-facing gable roof or projecting cornice

• Wood double-hung windows with ogee lugs

• Single or paired projecting bay(s) at front facade

• Front setback/location on lot in reference to street

• Offset entrance with original stair configuration

Romeo Flats: The Romeo flat, a San Francisco-based, high-density form of rental housing with four to six units, generally for working-class tenants, was typically built after the 1906 earthquake and fires. Romeo flats are multi-unit, residential buildings with three bays lining the façade. An open or enclosed, central winding staircase located in the

central bay divides the façade vertically. Balconies are located at each story of the central bay if it is open. When enclosed, windows are located at each landing. The district’s buildings along 16th Street include a row of Romeo Flats.

B. Materials and Finishes

Buildings in the district are of wood frame construction and were historically clad in horizontal wood siding. Exterior surface finishes are painted. Channel drop wood siding is typical at the secondary and rear facades, while a combination of flush lap, channel drop, clapboard, or shaped shingles are typically found at the primary facades. Most buildings retain their historic siding though a few were later clad in stucco, masonite, or composite shingle siding. These replacement siding materials have not gained significance.

Historically, there were several types of stairs constructed in the district: longer flights of wood stairs that typically project out from Italianate or Stick-Eastlake style buildings and shorter flights typically found within the recessed entries of Progressive-era flats and apartment buildings.

At the buildings along alleys and narrow streets, entry stairs were solid and uniform in appearance: featured closed risers, solid cheek walls beneath the stairs, turned wood balustrades, and capped newel posts, and had a painted finish. Some flights of stairs were later replaced with new wood stairs and balusters. Raised entrances to these smaller residential buildings lead to narrow openings highlighted with wood trim and bracketed hoods. Wood paneled and glazed doors with transom window sit within a shallow paneled recess.

heek walls beneath the stairs, turned wood balustrades, and capped newel posts, and had a painted finish. Some flights of stairs were later replaced with new wood stairs and balusters. Raised entrances to these smaller residential buildings lead to narrow openings highlighted with wood trim and bracketed hoods. Wood paneled and glazed doors with transom window sit within a shallow paneled recess.

Progressive-era buildings – Queen Anne or Classical Revival style – within the district, particularly those on 15th, 16th, and Dolores streets, feature wood or terrazzo steps with solid cheek walls and landings. These stairs are typically located partially within the building envelope and provide access to recessed entrance doors. The recessed vestibules have wood paneled walls, coffered or stucco-clad ceilings, and floors clad in wood, terrazzo, or tile (usually hexagonal tiles with a polychromatic trim or mosaic tile). Entrances of Progressive-era flats are typically flanked by Classical columns or pilasters, and decorated with applied plaster ornament, such as garlands and floral friezes.

While compatible, replacement stairs have not gained significance in their own right.

Existing gable roofs are typically finished with asphalt or composite shingles. Though generally compatible, these roofing materials have not gained significance.

C. Doors and Fenestration

Many of the district’s buildings retain their original primary entrance doors. These paneled wood doors, often slightly wider than contemporary entrance doors, are commonly glazed at the upper portion and feature corniced and bracketed hoods and incised or applied ornament. Occasionally, a single fixed window is located adjacent to the entry door of Queen Anne buildings, and many entry doors are topped with transom windows.

Fenestration is remarkably consistent throughout the district, consisting of vertically oriented double-hung single-light wood sash windows, with ogee lugs, set in wood surrounds. Windows are typically set in wide angled bays with smaller windows set flush with the facade, often adjacent to or above the primary entry. Window surrounds are typically topped with cornices, occasionally featuring pediments, with ornamented details. Smaller vertically oriented windows, set in a single or paired configuration, are typical on Italianate buildings. Several buildings, typically Progressive-era flats buildings, feature curved wood sash windows set in curved structural bays. Angled or curved bays typically contain three windows, though certain bays of corner buildings contain four or five windows. Most windows are rectangular although there are several buildings with arched windows. The building at 1949 15th Street is the only building that retains an original two-over-two light double-hung wood sash window on primary elevation.

Large flats buildings, particularly Romeo flats, have continuous stacked angled bays flanking enclosed central stair with flush window at each landing.

On visible side and rear elevations, windows are typically single or paired double-hung sash with simple wood surrounds.

While many buildings within the district retain some or all historic double-hung wood sash windows with ogee lugs on primary, street-facing elevations, many others have replacement sash. Replacement windows made of aluminum or vinyl sash, casement or slider windows, or windows with divided lights that were added to buildings after the Period of Significance have not gained significance.

The addition of garages has altered the front facades and yards of many District properties. Many of the historic buildings within the district were not originally constructed with an integrated automobile garage. Portions of site walls were removed and front yards partially paved to accommodate driveways for garages inserted in the basement of many buildings. Several properties feature detached or semi-attached pop-out garages in the front yard. Garage structures, openings, and driveways have not gained significance.

D. Architectural Details

Common traits found throughout the district are bay windows, gable roofs, parapets, decorative cornices, ornamental shingles, and spindle work, as well as more classically influenced detailing such as dentils, pediments, columns, and applied plaster ornament.

Late Victorian- and Progressive-era architectural styles predominate with Italianate, Stick-Eastlake, Queen Anne, and Classical Revival styles most widely represented. Architectural details commonly found on the district’s Italianate and Stick-Eastlake buildings – usually at the smaller dwellings on alleys and narrow streets – include cornice lintels, bracketed hoods, raised panel friezes and bracketed cornices, and false shaped parapets sometimes with pent roofs for Italianates (1959 15th Street includes chamfered bay window decorated with pipe colonnettes and arched window heads) and bracketed cornice caps, bracketed door hoods (flat or pedimented), false parapets with paneled friezes, brackets, and projecting cornices on Stick-Eastlakes.

The district’s larger flats buildings, facing onto the wider, primary streets, are typically Classical Revival style, including all the district’s Romeo Flats buildings. Buildings in the district in this style feature wide angled or round bay windows, flat roofs, bulky projecting cornices with modillions or dentils, raised panel spandrels, scroll keystones, broken entablatures, and pedimented and columned porch or portico entries.

Architectural details commonly found on Queen Anne buildings in the district include raked cornices, flared eaves, shingled tympanums, fish-scale shingling, projecting bracketed cornices, steeply pitched gable roofs, finials, geometric applied ornament at spandrel panels, dentils, friezes decorated with wood ornament, egg and dart molding, cut-out screens, sunbursts, intermediate cornices, window and door hoods, spindle screens, turned wood balustrades and newel posts, turned wood porch supports, a variety of wood cladding and patterned wood shingles, arched porticos, and Corinthian or Composite columns and pilasters.

This scope of work shall be limited, at the Department’s discretion, to no more than 15% of the total surface area of the façade. This work area must be stabilized and protected after the investigation is complete.

Fences

A Certificate of Appropriateness shall not be required for the construction or replacement of rear or side yard fences. Ground Disturbance

Most properties within the Alert Alley Early Residential District are also located within the Planning Department’s Archaeological Sensitivity Zone 1 (areas that have high sensitivity for archaeological resources that are at or just beneath the current ground surface). No Certificate of Appropriateness shall be required for any project where ground disturbance is not: 2 feet or deeper (depth below existing street elevation), and more than 25 cubic yards.

strict are also located within the Planning Department’s Archaeological Sensitivity Zone 1 (areas that have high sensitivity for archaeological resources that are at or just beneath the current ground surface). No Certificate of Appropriateness shall be required for any project where ground disturbance is not: 2 feet or deeper (depth below existing street elevation), and more than 25 cubic yards.

Where a project exceeds the ground disturbance criteria of Zone 1, no Certificate of Appropriateness shall be required where Planning Department cultural resources staff, after initial review, determines that the proposed development project is unlikely to result in damage or destruction of significant archaeological resources.

Non-Contributory Buildings

No Certificate of Appropriateness shall be required for any exterior change on elevations not visible from the public rights-of-way for non-contributory properties.

No Certificate of Appropriateness shall be required for any alteration or replacement of exterior building features on visible elevations of non-contributory properties, provided that reasonable efforts shall be made to produce compatibility with the District, and in no event shall there be a greater deviation from compatibility. The Planning Department will evaluate these proposals for compatibility with the character of the historic district as described in the designating ordinance, as set forth in Section 1006.6 of the Planning Code.

Preservation Design Standards

A Certificate of Appropriateness shall not be required for projects involving additions and modifications of district buildings that are also subject to the Housing Accountability Act (HAA), provided they comply with the adopted objective design standards outlined in the Preservation Design Standards.

Ordinary Maintenance and Repairs

No Certificate of Appropriateness shall be required if the proposed work consists of ordinary maintenance and repairs, as defined in Section 1005 (e)(3) of the Planning Code as any work, the sole purpose and effect of which is to correct deterioration, decay or damage of existing materials, including repair of damage caused by fire or other disaster.

Replacement of Character-Defining Features

A Certificate of Appropriateness shall not be required for the in-kind replacement of character-defining features that are deteriorated beyond repair, including historic architectural details such as porticos, porches, cornices, stringcourses, plaster work, tympanum, roofline, and eave, regardless of visibility from the public right-or-way.¹ For this standard, “in

kind” shall mean repair or replace exactly to match the historic feature’s material, dimensions, finish, profile, and details. Use of alternative material(s) does not qualify as “in-kind.”

Roofing – Repair or Replacement

No Certificate of Appropriateness shall be required for roof repair or replacement provided the proposed roof work does not change the roof character, form, structure, or character-defining features. New roofing shall be compatible with existing roofing.

No Certificate of Appropriateness shall be required for repair and/or replacement of roofing materials other than visible surface materials, including but not limited to underlayment, structural members, chimneys, gutters, and scuppers, that does not alter the existing roof’s form or character-defining features.

SEC. 9. ADDITIONAL PROVISIONS FOR ALTERATIONS, ADDITIONS AND NEW CONSTRUCTION.

Excluding the exceptions defined in this Appendix.¹ any exterior change to a contributory or non-contributory building or new construction within the Alert Alley Early Residential District shall require a Certificate of Appropriateness,

pursuant to the provisions of Article 10, when such work requires a City permit. The following standards shall guide the approval of exterior alterations, additions, and new construction.

(a) Character of the district. New construction shall complement and support the historic character of the district. Proposals for exterior alterations that result in greater conformity with the character of the district and are based on physical or documented evidence are encouraged.

(b) Historic Materials. Exterior alterations or new construction shall not destroy historic materials.¹ features and spatial relationships that characterize the property. Repair and retention of historic windows is encouraged.

(c) Compatibility. New construction shall be differentiated from the old and shall be compatible with the historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment. Additions shall be reviewed for compatibility with the historic building and the District, while infill construction shall be reviewed for compatibility with the overall District. Neither should imitate nor replicate existing features. Additions should not physically or visually dominate existing buildings in the District. Infill construction should reflect the character of the District, including the prevailing heights of contributing buildings without creating a false sense of history. The following standards shall guide the approval of additions and new construction:

Additions. Horizontal and vertical additions on contributing and non-contributing buildings, as well as addition of new features such as garages or window openings in visible elevations of contributing buildings, shall be reviewed on a case-by-case basis. Proposed additions should be located in an inconspicuous location and not result in a radical change to the form or character of the historic building or surrounding District. Due to their diminutive scale and the setbacks of many of the contributory buildings along the narrow alleys and side streets in the District, vertical additions to the contributory buildings facing Alert Alley and Landers Street are generally discouraged unless it is can be demonstrated that the addition does not impair the form or character-defining features of the building and that it is not visible from the surrounding public rights-of-way within the District.

utory buildings along the narrow alleys and side streets in the District, vertical additions to the contributory buildings facing Alert Alley and Landers Street are generally discouraged unless it is can be demonstrated that the addition does not impair the form or character-defining features of the building and that it is not visible from the surrounding public rights-of-way within the District.

As part of the Planning Department review process, the project sponsor shall conduct and submit an analysis that illustrates the relative visibility of a proposed vertical addition from within the District. As part of this analysis, sightline cross-sections and perspective drawings illustrating the proportionality and scale, as well as the visible extent of the addition from prescribed locations should be submitted.

The Planning Department will evaluate these proposals for compliance with the Secretary of the Interior’s Standards (as set forth in Section 1006.6 of the Planning Code), and, may, at their discretion, refer to the Site Design/Architecture standards of the Preservation Design Standards (adopted by Historic Preservation Commission).

New Construction. Where the District provides an opportunity for new construction through existing vacant parcels or by replacing non-contributing buildings, a sensitive design is of critical importance. The new construction shall respect the general size, shape, and scale of the character-defining features associated with the district and its relationship to the character-defining features of the immediate neighbors and the district. Contributory buildings within the District should be utilized and referenced for design context. For new construction, contemporary design that respects the District’s existing character-defining features without replicating historic designs is encouraged. The Planning Department will evaluate these proposals for compatibility with the character of the historic district as described in the designating ordinance, as set forth in Section 1006.6 of the Planning Code, and, when applicable, the Citywide Design Standards.

The following standards shall guide the approval of exterior alterations and new construction:

1. Style. New construction shall be compatible with the character-defining features of the district, yet is contemporary in design.

2. Scale and Proportion. New construction shall be compatible with the massing, size, and scale of the adjacent contributing buildings within the district.

3. Setbacks. New construction shall conform to existing setback patterns found in adjacent buildings and within the district.

4. Roofline. Gabled, cross-gabled, or hipped roof forms or flat roofs with projecting cornices are common within the district and new construction shall reference the massing and form of adjacent buildings.

5. Dormers and Additions. The enlargement or construction of dormers, penthouses and horizontal or vertical additions shall be designed in a manner that requires minimal change to the character-defining features of the subject building and the district in terms of materials, fenestration, cladding, massing and ornamentation.

6. Garages. The insertion of a garage shall minimize the physical and visual impacts on the character-defining features of the existing building and front yard setting. The design of garages and garage doors shall be unobtrusive and simple. Painted roll-up doors with panels and multi-lights are in keeping with the character of the district and are encouraged.

7. Driveways and Front Yard Setbacks. The addition of new driveways shall minimize the removal of landscaping and include permeable paving materials in order to minimize disruption to front yard setbacks and the character-defining features of the subject building and the district.

8. Details. Architectural details on new construction shall be contemporary, yet compatible with the characterdefining features found on the contributing buildings within the district. (Added by Ord. 15-26, File No. 251101, App. 2/13/2026, Eff. 3/16/2026) CODIFICATION NOTE
