RELATION TO PLANNING CODE AND THE PROVISIONS OF THE CHARTER OF THE CITY AND COUNTY OF SAN FRANCISCO. (a) Article 10 of the Planning Code is the basic law governing historic preservation in the City and County of San Francisco. This ordinance, being a specific application of Article 10, is both subject to and in addition to the provisions thereof. (b) Except as may be specifically provided to the contrary in this ordinance, nothing in this ordinance shall supersede, impair or modify any Planning Code provisions applicable to property in the Alert Alley Early Residential District, including but not limited to existing and future regulations controlling uses, height, bulk, lot coverage, floor area ratio, required open space, off-street parking and signs. (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. 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 multi-family 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, street-facing 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 wa

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. 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.

No Certificate of Appropriateness shall be required for adding, expanding or removing openings at elevations not visible from the public right of way. Garage Doors: A Certificate of Appropriateness shall not be required for the replacement of an existing garage door and/or trim provided that the new features are compatible in terms of material, pattern, finish, and fenestration. 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. Exploratory and Investigative Work 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. 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. 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. Rooftop Equipment (excluding cellular installations) A Certificate of Appropriateness shall not be required for the installation of rooftop equipment provided that the rooftop equipment is not visible from a public right-of-way and that the rooftop equipment is installed in a manner that may be easily removed in the future without disturbing any historic fabric. Security Measures A Certificate of Appropriateness shall not be required for installation or replacement of metal security doors, window grilles, or security gates on rear elevations regardless of visibility from the public right-of-way. Solar Panels A Certificate of Appropriateness shall not be required for the installation of solar panels, including the installation of structures that support solar panels, regardless of visibility, provided that the installation would not require alterations to the building greater than normally required to install a solar energy system, such as: (a) Set with a low profile, and (b) Mounted parallel with the slope of the roof (if roof is sloped greater than 1/12), and (c) Not visible from adjacent street sightlines if on a flat roof, and (d) Set in from the perimeter walls of the building, including the building’s primary façade. Windows Window Repair: Repair and retention of historic windows is encouraged. No Certificate of Appropriateness shall be required to correct deterioration, decay, or damage to existing historic windows, at any façade, including window glazing, sash, muntins, jambs, pulleys, sills and other historic window components. See “Ordinary Maintenance and Repairs.” Window Replacement – Windows visible from public right-of-way: No Certificate of Appropriateness shall be required for replacement of non-historic windows, provided that replacement windows are wood (original windows are assumed have been wood); are recessed between two and three inches from the surrounding exterior wall surfaces, measured from the primary exterior cladding to sash; have true divided lites or simulated divided lites with dark-colored spacers where sash feature muntins. Replacement windows are not required to be single-glazed even if the original windows are single-glazed. Vinyl windows are not permitted as a replacement for any window. Window Replacement – Windows not visible from public rights-of-way: No Certificate of Appropriateness shall be required for window replacement on façades not-visible from the public right-of-way, provided the replacement windows occur within the existing opening.

are not permitted as a replacement for any window. (Added by Ord. 15-26, File No. 251101, App. 2/13/2026, Eff. 3/16/2026) CODIFICATION NOTE

1. So in Ord.15-26. 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. 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.
