to live, and that contributes to the establishment of Ontario as a "complete community;"
6. Ensure adequate light, air, privacy, and open space for dwellings;
7. Establish architectural and design guidelines to encourage a high quality
appearance of new and remodeled structures;
8. Establish standards ensuring that new infill residential construction is consistent with
the character and fabric of existing neighborhoods, including densities, design and exterior appearance;
9. Protect residential properties from the hazards of traffic congestion, noise, fire,
explosion, noxious fumes, and other hazards;

innovative mixed-use development as an alternative to the typical suburban, use-segregated developments found throughout the Inland Empire, which is consistent with the goals and policies of the Vision, Policy Plan (General Plan), and City Council Priorities components of The Ontario Plan. Generally, mixed-use districts are intended for the creation of development projects that:
a. Create a dynamic, walkable, mixed-use environment;
b. Provide for a development pattern that encourages the use of public
transportation;
c. Provide for a mix of housing types that are within close proximity to retail
and service uses;
d. Establish high standards for the design and development of buildings,
infrastructure, and landscaping;
(Rev. 11.04.2025) Page 6.01-60 Ontario Development Code
Division 6.01—District Standards and Guidelines
e. Ensure a high degree of pedestrian and vehicular connectivity, and
enhance the vitality of commercial corridors within the City;
f. Facilitate the development of housing, retail, and office uses within close
proximity to one another, allowing residents to walk to retail and service uses, and transit services; and
g. In selected areas, locate buildings close to the street, so that streets and
squares feel enclosed, establishing outdoor rooms.
2. The intent of each established mixed-use district is as follows:
a. Downtown Mixed-Use Area. The Downtown Mixed-Use District (MU-1 zoning
district) is intended to accommodate an intensive mixture of vertical and horizontal retail and office uses at a development intensity of up to 2.0 FAR, and residential uses at a density of 25 to 75 DU/AC. The Downtown Mixed-Use District is intended to encourage the development and revitalization of the City's historic downtown district in such manner as to achieve the District's full potential as a unique shopping and residential area, as well as the City's focus for governmental, cultural, and educational activities.
b. East Holt Mixed-Use Area. The East Holt Mixed-Use District (MU-2 zoning
district) is intended to accommodate the intensification of the East Holt Boulevard Corridor with low-rise (up to 5 stories) buildings housing a mixture of retail and office uses at a development intensity of up to 2.0 FAR and 1.0 FAR, respectively, and residential uses at a density of 14 to 40 DU/AC. The intent of this zoning district is to create identity and place along the Holt Boulevard Corridor and provide a connection between the Downtown Mixed Use Area and the Ontario Airport Metro Center.
c. Euclid/Francis Mixed-Use Area. The Euclid/Francis Mixed-Use District (MU-11
zoning district) is intended to accommodate a low-rise (up to 3 stories) mixture of retail uses at an intensity of up to 1.0 FAR, and residential uses at a density of 14 to 25 DU/AC, that will create identity and place along the Euclid Avenue corridor.
B. Applicability. The standards and guidelines established by this Section shall apply to each of the City's mixed-use zoning districts. Furthermore, the provisions of this Section shall apply to all land subdivisions for mixed-use purposes, and any new mixed-use construction, addition, remodel, or reallocation requiring a building permit or other similar entitlement by the City.
C. Mixed Use Zoning District Development Standards. Development within the MU-1, MU-2, and MU-11 mixed-use zoning districts shall comply with the following standards:
1. MU-1 (Downtown Mixed Use Area) Zoning District.

within MU-1 zoning district, in conjunction with the inclusion of appropriate form-based development standards within this Section, to be established on a minimum per block basis.
c. Allowed Development Density/Intensity. Within the MU-1 zoning district,
residential development shall range from a minimum allowed density of 25 dwelling units per acre, to a maximum allowed density of 75.0 dwelling units per acre. Commercial-retail and/or office development shall not exceed 2.0 FAR.

requirements from existing dairies/feed lots shall apply to new residential, commercial, and/or industrial development or structures used for public assembly purposes from existing dairies/feed lots:

residential, commercial, or industrial development or structure used for public assembly and an existing animal feed trough, corral/pen or an existing dairy/feed lot including manure stockpiles and related wastewater detention basins.

specific plan area and new development will be addressed through the specific plan review procedure which may include buffers, expanded parkways, open space, and other approved measures to mitigate potential impacts.
