This chapter provides regulations applicable to development and new land uses in the residential zoning districts established by Section 19.40.010. The purposes of the individual residential zoning districts and the manner in which they are applied are as follows.
A. RS (Suburban Residential) District. The RS zoning district is applied to areas that remain predominantly rural or agricultural in character. Typical parcel sizes range from 20,000 square feet to 2 acres; clustered development with smaller parcel sizes may be allowed where average density does not exceed 2 units per acre. The RS zoning district is primarily intended to implement the Very Low Density residential land use designation of the General Plan. An RS zoning district may include specific minimum parcel size requirements for new subdivisions, expressed as a suffix to the RS zoning map symbol (for example, RS-2 and RS-1 mean 2-acre and 1-acre minimum lot areas, respectively; RS-20 means 20,000 square foot minimum lot areas).
B. R1 (Low Density Residential) District. The R1 zoning district is applied to areas appropriate for traditional neighborhoods consisting of attached or detached single-family housing units. Permitted densities range from a minimum of 2.1 to a maximum of 7 units per acre. The R1 zoning district is primarily intended to implement the Low Density Residential land use designation of the General Plan.
An R1 zoning district may include specific minimum parcel size requirements for new subdivisions, expressed as a suffix to the R1 zoning map symbol (for example, R1-10 and R1-15 mean 10,000-square-foot and 15,000-square-foot minimum lot areas, respectively).
C. R2 (Medium Density Residential) District. The R2 zoning district is applied to areas appropriate for medium density residential development with a mixture of housing types, including single-family homes, duplexes, and multi-family residential projects. The development standards and permit requirements of the R2 district are intended to preserve existing neighborhoods while providing for additional compatible development. Permitted densities range from a minimum of 6 to a maximum of 14 units per acre. The R2 zoning district is primarily intended to implement the Medium Density Residential land use designation of the General Plan.
D. R3 (Medium-High Density Residential) District. The R3 zoning district is applied to areas appropriate for medium-high density residential neighborhoods. Permitted densities range from a minimum of 14.1 to a maximum of 22 units per acre. Multi-family residential uses may be permitted to develop up to 30 dwelling units per acre when at least 15% of the units are deed restricted housing affordable to low-income households at or below 80% of Area Median Income (AMI). The R3 zoning district is primarily intended to implement the Medium-High Density Residential land use designation of the General Plan.
E. R4 (High Density Residential) District. The R4 zoning district is applied to parcels appropriate for high density residential living. Permitted densities range from a minimum of 20 to a maximum of 70 units per acre. The R4 zoning district is primarily intended to implement the High Density Residential land use designation of the General Plan.
F. RMU (Residential Mixed Use) District. The RMU district is characterized by predominantly residential development at medium to high densities. It allows for commercial or office uses on the same property as residential uses, either vertically or horizontally. It does not preclude development that is entirely residential or entirely commercial. Other primary uses, including certain commercial uses, may be allowed by right or with approval of a use permit in compliance with Table 4-2. The RMU zoning district is primarily intended to implement the Residential Mixed Use designation of the General Plan. Permitted densities range from a minimum of 10 to a maximum of 20 units per acre. Multi-family residential uses may be permitted to develop up to 30 dwelling units per acre when at least 15% of the units are deed restricted housing affordable to low-income households at or below 80% of AMI.
