5.03.000: Purpose

The purpose of this Division is to provide operating, site planning and/or development standards for certain land uses allowed by Division 5.02 (Land Use) of this Development Code, and for activities and facilities that require special standards to mitigate their potential adverse impacts, thereby assuring a land use, activity, and/or facility of stable and desirable character, which is compatible with existing and future development and land uses in the vicinity, and protects the use and enjoyment of neighboring properties consistent with goals and policies of The Ontario Plan.

5.03.005: Applicability

A. The land uses, activities and facilities addressed by this Division shall be located in compliance with Division 5.02 (Land Use) of this Development Code.

2. Height.

a. Except as otherwise provided by Subsections E.2.b and E.2.c, below, a detached ADU created on a lot with an existing or proposed single-family or multiple-family dwelling unit may not exceed 16 FT in height.

b. A detached ADU may be up to 18 FT in height if it is created on a lot with an existing or proposed single-family or multiple-family dwelling unit that is located within one-half mile walking distance of a major transit stop or a high quality transit corridor, as those terms are defined in Section 21155 of the Public Resources Code, and the ADU may be up to 2 additional feet in height (for a maximum of 20 FT) if necessary to accommodate a roof pitch on the ADU that is aligned with the roof pitch of the primary dwelling unit.

c. A detached ADU created on a lot with an existing or proposed multiplefamily dwelling that has more than one story above grade may not exceed 18 FT in height.

d. An ADU that is attached to the primary dwelling may not exceed 25 FT in height or the height limitation imposed by the underlying zone that applies to the primary dwelling, whichever is lower. Notwithstanding the foregoing, ADUs subject to this Subsection E.2.d may not exceed 2 stories.

e. For purposes of this Subsection E.2, height is measured from existing legal grade or the level of the lowest floor, whichever is lower, to the peak of the structure.

3. Fire Sprinklers.

a. Fire sprinklers are required in an ADU or JADU if sprinklers are required in the

primary residence.

b. The construction of an ADU or JADU does not trigger a requirement for fire sprinklers to be installed in the existing primary dwelling.

4. Rental Term. No ADU or JADU may be rented for a term that is shorter than 30 days. This prohibition applies regardless of when the ADU or JADU was created.

5. No Separate Conveyance. An ADU or JADU may be rented, but, except as provided in Government Code section 66341, no ADU or JADU may be sold or otherwise conveyed separately from the lot and the primary dwelling (in the case of a single-family lot) or from the lot and all of the dwellings (in the case of a multiple-family lot).

6. Septic System. If the ADU or JADU will connect to an onsite wastewater-treatment system, the owner must include with the application a percolation test completed within the last 5 years or, if the percolation test has been recertified, within the last 10 years.

7. Owner Occupancy.

  • a. ADU . ADU’s are not subject to an owner-occupancy requirement.

Page 5.03-8

(Rev. 02.17.2026)

Ontario Development Code

Division 5.03—Supplemental Land Use Regulations

b. JADUs .

(1) Generally . As required by state law, JADUs are generally subject to an owner-occupancy requirement. A natural person with legal or equitable title to the property must reside on the property, in either the primary dwelling or JADU, as the person's legal domicile and permanent residence.

(2) Exception. The owner-occupancy requirement in this Subsection

E.7.b does not apply in either of the following situations:

(a) The JADU has separate sanitation facilities (i.e., does not

share sanitation facilities with the existing primary dwelling unit structure).

(b) The property is entirely owned by another governmental

agency, land trust, or housing organization.

8. Deed Restriction. Prior to issuance of a certificate of occupancy for a JADU, a deed restriction must be recorded against the title of the property in the County Recorder’s office and a copy filed with the Planning Director. The deed restriction must run with the land and bind all future owners. The form of the deed restriction will be provided by the city and must provide that:

a. The JADU may not be sold separately from the primary dwelling.

b. The JADU is restricted to the approved size and to other attributes allowed

by this section.

c. The deed restriction runs with the land and may be enforced against future property owners.

d. The deed restriction may be removed if the owner eliminates the JADU, as evidenced by, for example, removal of the kitchen facilities. To remove the deed restriction, an owner may make a written request of the Planning Director, providing evidence that the JADU has in fact been eliminated. The Planning Director may then determine whether the evidence supports the claim that the JADU has been eliminated. Appeal may be taken from the Planning Director’s determination consistent with other provisions of this Code. If the JADU is not entirely physically removed, but is only eliminated by virtue of having a necessary component of a JADU removed, the remaining structure and improvements must otherwise comply with applicable provisions of this Code.

e. The deed restriction is enforceable by the Planning Director or his or her designee for the benefit of the city. Failure of the property owner to comply with the deed restriction may result in legal action against the property owner, and the City is authorized to obtain any remedy available to it at law or equity, including, but not limited to, obtaining an injunction enjoining the use of the JADU in violation of the recorded restrictions or abatement of the illegal unit.

9. Building and Safety.

a. Must Comply with Building Code. Subject to Subsection E.10.b, below, all ADUs and JADUs must comply with all local building code requirements.

Page 5.03-9

Ontario Development Code

(Rev. 02.17.2026)

Division 5.03—Supplemental Land Use Regulations

b. No Change of Occupancy. Construction of an ADU does not constitute a Group R occupancy change under the local building code, as described in Section 310 of the California Building Code, unless the building official or Community Improvement Division officer makes a written finding based on substantial evidence in the record that the construction of the ADU could have a specific, adverse impact on public health and safety. Nothing in this Subsection E.9.b prevents the City from changing the occupancy code of a space that was uninhabitable space or that was only permitted for nonresidential use and was subsequently converted for residential use in accordance with this Section.

10. Certificate of Occupancy Timing.

a. Generally. No certificate of occupancy for an ADU or JADU may be issued before the certificate of occupancy is issued for the primary dwelling unit.

b. Limited Exception for State-declared Emergencies. Notwithstanding Subsection E.10.a above, a certificate of occupancy for an ADU may be issued before a certificate of occupancy for the primary dwelling if each of the following requirements are met: (1) The County is subject to a proclamation of a state of emergency made by the California Governor on or after February 1, 2025.

(2) The primary dwelling was substantially damaged or destroyed by an event referenced in the Governor’s state of emergency proclamation.

(3) The ADU has been issued construction permits and has passed all (4) The ADU is not attached to the primary dwelling.

F. Specific ADU Requirements. The following requirements apply only to Class 2 ADUs that are approved under Subsection D.2, above. This Subsection F does not apply to Class 1 ADUs or JADUs approved under Subsection D.1, above.

1. Maximum Size.

a. The maximum size of a detached or attached ADU subject to this Subsection F is 850 SF of interior livable space for a studio or one-bedroom unit and 1,000 SF of interior livable space for a unit with 2 or more bedrooms. b. An attached ADU that is created on a lot with an existing primary dwelling is further limited to 50 percent of the floor area of the existing primary dwelling.

c. Application of other development standards in this Subsection F, such as lot coverage, might further limit the size of the ADU, but no application of the percent-based size limit in Subsection F.1.b, above, or front setback, lot coverage limit, or open-space requirement may require the ADU to have less than 800 SF of interior livable space.

2. Setbacks.

a. ADUs that are subject to this Subsection F must conform to 4-FT side and rear setbacks. ADUs that are subject to this Subsection F must maintain a minimum front yard

Division 5.03—Supplemental Land Use Regulations

e. The interior horizontal dimensions of an ADU must be at least 10 FT wide in every direction, with a minimum interior wall height of 7 FT.

f. No window or door of the ADU may have a direct line of sight to an adjoining residential property. Each window and door must either be located where there is no direct line of sight or screened using fencing, landscaping, or privacy glass to prevent a direct line-of-sight.

g. All windows and doors in an ADU less than 30 FT from a property line that is not a public right-of-way line must either be (for windows) clerestory with the bottom of the glass at least 6 FT above the finished floor, or (for windows and for doors) utilize frosted or obscure glass.

8. Landscape Requirements. A Landscape Plan shall be submitted to the City, which provides for evergreen landscape screening, to include trees, shrubs, and groundcovers that shall be planted, permanently irrigated, and fully maintained, and which is located between an ADU and adjacent parcels, and where an ADU impacts a front yard and/or is subject to public views from a public or private street. Evergreen landscape screening must be planted and maintained between an ADU and adjacent parcels as follows:

scape screening, to include trees, shrubs, and groundcovers that shall be planted, permanently irrigated, and fully maintained, and which is located between an ADU and adjacent parcels, and where an ADU impacts a front yard and/or is subject to public views from a public or private street. Evergreen landscape screening must be planted and maintained between an ADU and adjacent parcels as follows:

a. At least one 15-gallon size screening shrubs shall be installed at every 5 linear feet of exterior ADU wall. Alternatively, a 6-FT high decorative masonry block wall may be constructed. b. ADUs created by garage conversion, which results in the removal of the garage door, shall provide a minimum 3-FT wide foundation landscape planter for the full length of the wall wherein the garage door was removed, which shall be fully landscaped and irrigated, and permanently maintained.

c. All landscaping must be drought tolerant and California friendly.

d. Landscape and irrigation plans shall be prepared and submitted to the City for review and approval.

9. Historical Protections. An ADU that is on or within 600 feet of real property that is listed in the California Register of Historic Resources must be located so as to not be visible from any public right-of-way.

10. Allowed Stories. No ADU subject to this Subsection F may have more than one story, except that an ADU that is attached to the primary dwelling may have the stories allowed under subparagraph E.2.d of this Section.

G. Fees. The following requirements apply to all Class 1 ADUs and JADUs and Class 2 ADUs that are approved under Subsections D.3.a or D.3.b, above. 1. Impact Fees.

a. No impact fee is required for a JADU or for an ADU that has less than 750 SF of interior livable space. For the purposes of this Subsection G.1, the term "impact fee" means a "fee" under the Mitigation Fee Act (Government Code Section 66000(b)) and a fee under the Quimby Act (Government Code Section 66477). "Impact fee" as used here does not include any connection fee or capacity charge for water or sewer service.

Page 5.03-13

Ontario Development Code

(Rev. 02.17.2026)

Division 5.03—Supplemental Land Use Regulations

b. A JADU or ADU with less than 500 SF of interior livable space does not increase assessable space by 500 SF for purposes of Education Code Section 17620(a)(1)(C), and is therefore not subject to school fees under Education Code Section 17620.

c. Any impact fee that is required for an ADU that has 750 SF or more of interior livable space must be charged proportionately in relation to the square footage of the primary dwelling unit. (E.g., the floor area of the ADU, divided by the floor area of the primary dwelling, times the typical fee amount charged for a new dwelling.)

2. Utility Fees.

a. If an ADU or JADU is constructed with a new single-family home, or if a detached new-construction ADU is being constructed on a lot with an existing single-family home, a separate utility connection directly between the ADU or JADU and the utility may be required. A connection fee and capacity charge may be required. b. Except as described in Subsection G.2.a, JADUs and converted ADUs on a single-family lot that are created under Subsections D.3.a(1) above are not required to have a new or separate utility connection directly between the JADU or ADU and the utility. Nor is a connection fee or capacity charge required. Notwithstanding the rest of this paragraph, a direct utility connection is required for separate conveyance of an ADU when separate conveyance is allowed under this code.

c. Except as described in Subsection G.2.a, all ADUs that are not covered by Subsection G.2.b require a new, separate utility connection directly between the ADU and the utility for any utility that is provided by the city. All utilities that are not provided by the city are subject to the connection and fee requirements of the utility provider.

(1) The connection is subject to a connection fee or capacity charge that is proportionate to the burden created by the ADU based on either the floor area or the number of drainage-fixture units (DFU) values, as defined by the Uniform Plumbing Code, upon the water or sewer system.

(2) The portion of the fee or charge that is charged by the city may not

exceed the reasonable cost of providing this service.

H. Nonconforming Zoning Code Conditions, Building Code Violations, and Unpermitted Structures.

1. Generally. The City will not deny an ADU or JADU application due to a nonconforming zoning condition, building code violation, or unpermitted structure on the lot that does not present a threat to the public health and safety and that is not affected by the construction of the ADU or JADU.

2. Unpermitted ADUs constructed before 2020.

a. Permit to Legalize. As required by state law, the City may not deny a permit to legalize an existing, but unpermitted ADU or JADU that was constructed before January 1, 2020, if denial is based on either of the following grounds:

(1) The ADU or JADU violates applicable building standards; or

Page 5.03-14

(Rev. 02.17.2026)

Ontario Development Code

Division 5.03—Supplemental Land Use Regulations

(2) The ADU or JADU does not comply with state ADU or JADU law or this ADU ordinance (Section 5.03.010).

b. Exceptions.

(1) Notwithstanding Subsection H.2.a, above the City may deny a permit to legalize an existing but unpermitted ADU or JADU that was constructed before January 1, 2020, if the City makes a finding that correcting a violation is necessary to comply with the standards specified in California Health and Safety Code Section 17920.3.

(2) Subsection H.2.a, above does not apply to a building that is deemed to be substandard in accordance with California Health and Safety Code Section 17920.3.

I. Nonconforming ADUs and Discretionary Approval. Any proposed ADU or JADU that would otherwise be allowed under this section but that does not conform to the objective design or development standards set forth in Subsections A through H of this Section may be allowed by the City, subject to a Conditional Use Permit issued in accordance with the other provisions of this Development Code.

5.03.015: Adult-Oriented Businesses

The following regulations shall govern the establishment and operation of adult-oriented businesses within the City:

A. Purpose. It is the intent of these Adult-Oriented Business regulations to prevent communitywide adverse economic impacts, increased crime, decreased property values, and the deterioration of neighborhoods, which can be brought about by locating Adult-Oriented Businesses in close proximity to each other or proximity to other incompatible uses such as schools, churches, and residentially zoned districts or uses. The City Council finds that it has been demonstrated in various communities that the concentration of Adult-Oriented Businesses causes an increase in the number of transients in the area, and an increase in crime, and in addition to the effects described above, can cause other businesses and residents to move elsewhere. It is, therefore, the purpose of these Adult-Oriented Business regulations to establish reasonable and uniform regulations to ameliorate the harmful effects of Adult-Oriented Businesses or their close proximity to incompatible uses, while providing reasonable alternative avenues of communication.

Moreover, it is also the purpose of these Adult-Oriented Business regulations to facilitate regulation of Adult-Oriented Businesses and the performers that may be employed by such establishments pending resolution of the prior permitting issues raised in Baby Tam & Co., Inc. v. City of Las Vegas, 154 F.3d 1097 (9th Cir. 1998). The intent of the registration requirements contained in these Adult-Oriented Business regulations is to provide enforcement agencies with sufficient information to assist them in ensuring that criminal elements do not infiltrate AdultOriented Businesses, that minors are not employed by such establishments, and that the establishments will comply with the zoning and operational standards imposed by these AdultOriented Business regulations.

B. Findings. The City Council of the City of Ontario, California, hereby, finds as follows:

1. The City Council finds that various studies and court decisions presented to the City Council have determined that the establishment of Adult-Oriented Businesses is linked to increases in crime and other adverse effects. The City, in enacting this ordinance, more specifically finds that these studies provide convincing evidence that:

Page 5.03-19

Ontario Development Code

(Rev. 02.17.2026)

Division 5.03—Supplemental Land Use Regulations

a. Adult-Oriented Businesses are linked to, and associated with, increases in crime rates in those areas in which they are located and in surrounding areas;

b. Both the proximity of Adult-Oriented Businesses to sensitive land uses and the concentration of Adult-Oriented Businesses tend to result in the blighting and deterioration of the areas next to which, and near which, they are located;

c. There is substantial evidence that an increase in crime tends to accompany, concentrate around, and be aggravated by Adult-Oriented Businesses, including but not limited to an increase in the crimes of narcotics distribution and use, prostitution, pandering, and violence against persons and property. The studies from other cities establish convincing evidence that Adult-Oriented Businesses that are not regulated as to permissible locations often have a deleterious effect on nearby businesses and residential areas, causing, among other adverse secondary effects, an increase in crime and a decrease in property values;

d. Studies concerning increases in crime surrounding Adult-Oriented Businesses are further supported by the City's own experiences confirming an inordinate amount of police response calls to the City's two existing Adult-Oriented Businesses, "the Reel One" and "the Villa Theater." The police response statistics from the Ontario Police Department for the period from 1996 to 1998 indicate that City police have been called out to these locations over 70 times to investigate solicitation and prostitution activities, lewd conduct, indecent exposure, illegal drug use and possession, use of counterfeit money, thefts, burglaries, and other disturbances;

2. Based on the forgoing, the City Council finds and determines that special regulation of Adult-Oriented Businesses is necessary to ensure that their adverse secondary effects will not cause or contribute to an increase in crime rates or the blighting or deterioration of the areas in which they are located or surrounding areas. The need for such special regulations is based upon the recognition that Adult-Oriented Businesses not only cause adverse secondary effects, but also have seriously objectionable operational characteristics, particularly when several of them are concentrated under certain circumstances or located in direct proximity to sensitive uses, thereby having a deleterious effect upon an adjacent area. It is the purpose and intent of these regulations to prevent or mitigate such adverse secondary effects;

3. The protection and preservation of the public health, safety and welfare require that certain distances be maintained between Adult-Oriented Businesses and other sensitive uses, including residential, religious and educational uses, as well as to minimize the adverse secondary effects between the proximity of Adult-Oriented Businesses and other Adult-Oriented Businesses and truck stops. Moreover, the locational requirements established by this Section do not unreasonably restrict the establishment or operation of constitutionally protected Adult-Oriented Businesses in the City. A sufficient and reasonable number of appropriate locations for the operation of Adult-Oriented Businesses will remain available after the enactment of these AdultOriented Business regulations.

uck stops. Moreover, the locational requirements established by this Section do not unreasonably restrict the establishment or operation of constitutionally protected Adult-Oriented Businesses in the City. A sufficient and reasonable number of appropriate locations for the operation of Adult-Oriented Businesses will remain available after the enactment of these AdultOriented Business regulations.

4. The City Council also finds that locational criteria alone do not adequately protect the health, safety, and general welfare of the citizens of the City, and thus, certain requirements with respect to the ownership and operation of Adult-Oriented Businesses are in the public interest. In addition to the findings and studies conducted in other cities regarding increases in crime rates, decreases in property values, and the blighting of areas in which Adult-Oriented Business are located, the city Council also takes legislative notice of the facts recited in the case of Kev, Inc., v. Kitsap County (9th Cir. 1986) 793 F.2d 1053, and Colacurcio v. City of Kent , 1998 WL 848036 (9th

Page 5.03-20

(Rev. 02.17.2026)

Ontario Development Code

Division 5.03—Supplemental Land Use Regulations

Cir.), regarding how live adult entertainment results in adverse secondary effects such as prostitution, drug dealing, and other law enforcement problems;

5. Zoning, permitting, licensing, and other police power regulations are legitimate, reasonable means of accountability to help protect the quality of life in the City and to help assure that owners, operators and performers of Adult-Oriented Businesses comply with reasonable regulations and are located in places that minimize the adverse secondary effects that naturally accompany the operation of Adult-Oriented Businesses;

6. The City Council recognizes that possible harmful effects on children and minors exposed to the secondary effects of Adult-Oriented Businesses, the deterioration of respect for family values, and the need and desire of children and minors to stay away from, and avoid, Adult-Oriented Businesses, which causes children to be fearful and cautions when walking through or visiting the immediate neighborhood of these businesses. The City Council desires to: minimize and control the adverse secondary effects associated with the operation of Adult-Oriented Businesses and thereby protect the health, safety, and welfare of the citizens of Ontario, and in particular, the health, safety, and welfare of children and minors in the City; protect the citizens from increased crime; preserve their quality of life; preserve property values and the character of surrounding neighborhoods and businesses; deter the spread of urban blight and protect against the threat to health from the spread of communicable and sexually transmitted diseases;

Ontario, and in particular, the health, safety, and welfare of children and minors in the City; protect the citizens from increased crime; preserve their quality of life; preserve property values and the character of surrounding neighborhoods and businesses; deter the spread of urban blight and protect against the threat to health from the spread of communicable and sexually transmitted diseases;

7. Nothing in these Adult-Oriented Business regulations is intended to authorize, legalize, or permit the establishment, operation, or maintenance of any business, building, or use that violates any applicable City ordinance or any statute of the State of California relating to public nuisances, unlawful or indecent exposure, sexual conduct, lewdness, obscene or harmful matter, or the exhibition or public display thereof;

8. The City Council further finds the following, in part, based upon its understanding of the judicial decisions and the reports, studies and other documents in the public record: a. Evidence indicates that the existence of Adult-Oriented Businesses that permit nudity have been shown in some cities to increase the secondary effects of crime and decrease property values;

b. Evidence has demonstrated that Performers employed by Adult-Oriented Businesses have been found to offer and provide private shows to patrons who, for a price, are permitted to observe and participate with the performers in live sex shows; c. Evidence indicates that performers at Adult-Oriented Businesses have been found to engage in acts of prostitution with patrons of the establishment;

d. Evidence indicates that fully enclosed booths, individual viewing areas, and other small rooms whose interiors cannot be seen from public areas of the Adult-Oriented Business regularly have been found to be used as locations for engaging in unlawful sexual activity; and

e. As a result of Subparagraphs B.8.a through d, above, and the increase in the incidence of AIDS and Hepatitis B, which are both sexually transmitted diseases, the City Council has a substantial interest in adopting regulations that will reduce to the greatest extent possible, the possibility for the occurrence of casual sex acts at Adult-Oriented Businesses;

Page 5.03-21

Ontario Development Code

(Rev. 02.17.2026)

Division 5.03—Supplemental Land Use Regulations

9. In regulating nudity and semi-nudity in Adult-Oriented Businesses, the City Council does not intend to proscribe the communication of erotic messages or any other communicative element or activity, but rather only to regulate nudity and semi-nudity in Adult-Oriented Businesses due to the adverse secondary effects associated therewith, including prostitution, sexual assault, and associated crimes;

10. The City Council further finds, as a wholly independent basis, that it has a substantial public interest in preserving societal order and morality, and that such interest is furthered by the regulation of nudity and semi-nudity in Adult-Oriented Businesses;

11. While the City Council desires to protect the rights conferred by the United States and California Constitutions on Adult-Oriented Businesses, it does so in a manner that ensures the continued and orderly development of property within the City and diminishes, to the greatest extent feasible, those undesirable secondary adverse effects which the Studies have shown to be associated with the development and operation of Adult-Oriented Businesses;

12. In enacting nudity and semi-nudity regulations pursuant to these Adult-Oriented Business regulations, the City Council declares that the regulations do not create or regulate a criminal offense, and the City Council has not provided a criminal penalty for a violation of these regulations; 13. The City Council finds that preventing the direct exchange of money between Performers and Patrons also reduces the likelihood of drug and sexual transactions occurring in Adult-Oriented Businesses;

14. Requiring a 10-FT separation between performers and patrons reduces the likelihood that these persons will negotiate narcotics sales, or negotiate for the purpose of engaging in sexual activities or obtaining sexual favors within the Adult-Oriented Businesses; and 15. Enclosed or concealed booths and dimly lit areas within Adult-Oriented Businesses greatly increase the potential for misuse of the premises, including unlawful conduct of a type that facilitates transmission of disease. Requirements that all indoor areas be open to view by management at all times and that adequate lighting be provided are necessary in order to reduce the opportunity for, and, therefore, the incidence of illegal conduct within Adult-Oriented Businesses, and to facilitate the inspection of the interior of the premises thereof by law enforcement personnel.

C. Definitions. As used in these Adult-Oriented Business regulations, the following words, terms, and phrases are defined as follows:

1. Applicant. A person who is required to file an application for a registration certificate under these Adult-Oriented Business regulations, including an individual owner, managing partner, officer of a corporation, or any other operator, manager, employee, or agent of an Adult-Oriented Business.

2. Bar. Any commercial establishment licensed by the State Department of Alcoholic Beverage Control to serve any alcoholic beverages on the premises.

3. Chief of Police. The Chief of Police of the City of Ontario or his or her designee.

4. City Council. The City Council of the City of Ontario.

5. Day. A calendar day and not business day. Whenever "day" is used to identify requirements of these Adult-Oriented Business regulations to be performed on a particular day, which day falls upon a holiday, Saturday or Sunday, the day for performance of the requirements of these Adult-Oriented Business regulations will be the next business day after the holiday, Saturday or Sunday.

6. Distinguished or Characterized by an Emphasis Upon. The dominant or essential theme of the object described by the phrase. For example, when the phrase refers to films "which are distinguished or characterized by an emphasis upon "the depiction or description of specified sexual activities or specified anatomical areas, the films so described are those whose dominant or predominant character and theme are the depiction of the enumerated sexual activities or anatomical areas.

7. Establishment of an Adult-Oriented Business. Means and includes any of the following:

a. The opening or commencement of any Adult-Oriented Business as a new

However, unless there is a compelling reason, these design guidelines shall be observed.

1. Architecture.

a. Style. The construction of the building should depict a specific architectural style by distinctive elements and features consistent with the chosen style. Accessory structures should portray the style through their features as well. The style of the building should also reflect and complement the styles of surrounding commercial buildings. Architectural treatment should

Page 5.03-66

(Rev. 02.17.2026)

Ontario Development Code

Division 5.03—Supplemental Land Use Regulations

be employed over the entire building exterior (360-degree architecture), and the building should be individually designed for its site. The use of standardized corporate architectural styles is highly discouraged.

Entries should project 10 to 12 FT from the building in order to add depth and variation to the façade.

d. Entry Design. Gables, awnings, sign locations, or other features should clearly express the location of doorways. Greater attention should be given to materials and detailing adjacent to entries.

e. Arcades and Awnings. Outdoor arcades are encouraged to protect pedestrians from summer heat and winter rain. Where an arcade is not provided, a separate awning or other architectural feature should be used for each business to enhance the individual identity of small shops. Because they can quickly deteriorate, canvas awnings are discouraged, or should be properly maintained.

f. Roof Forms. Roof forms should reflect the architectural style and internal organization of buildings. Hipped and gable roofs are encouraged. Flat roof parapets should be accompanied by a cornice or other shadow-creating detail at its "top." g. Drive-Up Windows. Construct roofs or trellises over drive-up windows. Posts supporting roofs or trellises should be substantial in appearance and fully integrated into the architecture of the building. The stacking area for drive-up windows should be screened from the street through a combination of low walls and landscaping. h. Lighting.

(1) On-site lighting shall be directed away or shielded from adjacent freeways, roads, streets, and adjacent properties. All exterior lighting shall be of an indirect nature, coming from under eaves and canopies, or at ground level, with in landscaped areas.

(2) Exterior lighting fixtures should be a decorative and reinforce the

architectural style of the building.

(3) Light standards less than 15 FT in height (including lighting bollards) should illuminate all street sidewalks and connecting walkways and are encouraged throughout the project.

i. Landscaping.

(1) The minimum amount of on-site landscaping, including defined plazas and courtyards, shall equal 15 percent of the net lot area. Landscaping should be used on the site to show transition from adjacent uses, define a circulation pattern on the lot, screen the

Page 5.03-67

Ontario Development Code

(Rev. 02.17.2026)

Division 5.03—Supplemental Land Use Regulations

parking lot from the street, highlight entries, provide shade for parking as well as outdoor seating areas, and to soften the appearance of the building.

(2) At a minimum, landscaping shall include 15-gallon trees planted no more than 20 FT on center, within minimum 5-FT wide planters. A suitable plant material (grasses, ivy, etc.) should be used as ground cover. Minimum 10-FT wide planters containing a combination of hedges and low walls shall be used to screen drive-thru lanes from view of public streets.

(3) Pedestrian walkways should not intersect drive-thru lanes; however, in the event this occurs, adequate visibility for pedestrians and vehicles shall be provided, and pedestrian crossings shall be clearly marked with signs.

j. Play Structures.

(1) Play structures should be placed indoors, becoming an integral part of the architecture, yet remaining a subordinate element. If located outside, play structures shall be oriented away from the public street and properly screened, and shall be no more than 11 FT in height.

(2) Indoor restaurant playground facilities shall be ancillary to the restaurant use. Scale and massing shall not dominate the main structure and the height of the playground facility shall not exceed the height of the main roof of the main structure.
