(Ord. 930, § 2, passed 06-12-2017)

18.21.020 - Purposes of the Residential Zoning Districts

The purposes of the individual residential zoning districts and the manner in which they are applied are as follows.

A.    RR (Rural Residential) zoning district. The RR zoning district is applied to areas on the northern fringes of the City that are appropriate for single-family dwellings in a semi-rural environment that can also accommodate lower intensity agricultural land uses. The maximum allowable residential density within the RR district ranges from 1 dwelling unit per 5 acres to 1 dwelling unit per acre, with the maximum density allowed on specific property being identified on the Zoning Map by means of a numerical suffix to the RR zoning district symbol (see § 18.21.040 - Residential District Subdivision Standards). The RR zoning district implements and is consistent with the RR land use designations of the Inland General Plan.

B.    RS (Suburban Residential) zoning district. The RS zoning district is applied to areas of the City that are appropriate for single-family dwellings, but where infrastructure limitations and/or environmental constraints limit the ability for development to achieve urban densities. The maximum allowable residential density within the RS district ranges from 1 to 3 dwelling units per acre, with the maximum density allowed on specific property being identified on the Zoning Map by means of a numerical suffix to the RS zoning district symbol (see § 18.21.040 - Residential District Subdivision Standards). The RS zoning district implements and is consistent with the RS land use designation of the Inland General Plan.

C.    RL (Low Density Residential) zoning district. The RL zoning district is applied to areas of the City that are appropriate for neighborhoods of single-family dwellings on standard urban lots, surrounding the more densely developed core of the City. This zone also allows limited, neighborhood serving commercial uses on small, appropriately located individual parcels, or as small, pedestrian-oriented neighborhood centers. The maximum allowable residential density within the RL district ranges from 3 to 6 dwelling units per acre; the maximum floor area ratio (FAR) for nonresidential uses is 0.40. The RL zoning district implements and is consistent with the RL land use designation of the Inland General Plan.

D.    RM (Medium Density Residential) zoning district. The RM zoning district is applied to areas of the City that are appropriate for neighborhoods with a variety of housing types located in proximity to parks, schools, and public services. This zone also allows limited, neighborhood serving commercial uses on small, appropriately located individual parcels, or as small, pedestrian-oriented neighborhood centers. The maximum allowable residential density within the RM district ranges from 6 to 12 dwelling units per acre; the maximum floor area ratio (FAR) for nonresidential uses is 0.40. The RM zoning district implements and is consistent with the RM land use designation of the Inland General Plan.

E.    RH (High Density Residential) zoning district. The RH zoning district is applied to areas of the City that are appropriate for a variety of higher density housing types, primarily on larger parcels where innovative site design can provide the desired mixture of housing types, aesthetic and functional open space areas, and other features that enhance the development and neighborhood. This zone also allows limited, neighborhood serving commercial uses on small, appropriately located individual parcels, or clusters of retail establishments. The maximum allowable residential density within the RH district ranges from 10 to 15 dwelling units per acre; the maximum floor area ratio (FAR) for nonresidential uses is 0.40. The RH zoning district implements and is consistent with the RH land use designation of the Inland General Plan.

F.    RVH (Very High Density Residential) zoning district. The RVH zoning district is applied to areas of the City that are appropriate for high density multifamily housing near commercial areas and public services. This zone also allows limited, neighborhood serving commercial uses on small, appropriately located individual parcels or clusters of retail establishments. The maximum allowable residential density within the RVH district ranges from 12 to 24 dwelling units per acre; the maximum floor area ratio (FAR) for nonresidential uses is 0.40. The RVH zoning district implements and is consistent with the RVH land use designation of the Inland General Plan.

(Ord. 930, § 2, passed 06-12-2017)

18.21.030 - Residential District Allowable Land Uses and Permit Requirements

A.    General permit requirements. Table 2-1 identifies the uses of land allowed by this Development Code in each residential zoning district, and the planning permit required to establish each use, in compliance with § 18.20.030 (Allowable Land Uses and Planning Permit Requirements).

B.    Requirements for certain specific land uses. Where the last column in Table 2-1 (Specific Use Regulations”) includes a section number, the referenced section may affect whether the use requires a Zoning Clearance, Minor Use Permit, or Use Permit, and/or may establish other requirements and standards applicable to the use.

18.21.040 - Residential District Subdivision Standards

A.    Each subdivision shall comply with the minimum parcel size requirements shown in Table 2-2 for the applicable zoning district.

B.    The minimum parcel size requirements for a specific subdivision are determined by the review authority as part of subdivision approval. The review authority may require 1 or more parcels within a specific subdivision to be larger than the minimums required by this table based on potential environmental impacts, the physical characteristics of the site or surrounding parcels, and/or other factors.

C.    A condominium or other common interest project may be subdivided with smaller parcels for ownership purposes, with the minimum lot area determined through subdivision review; provided, that the overall development site complies with the minimum parcel size, and the total number of any dwellings complies with the maximum density for the applicable zone.
