R-2
Medium Density Multi-Family Residential District
The R-2 zoning districts are applied to areas of the City appropriate for residential neighborhoods with medium and higher residential densities, to provide home rental and ownership opportunities, and to provide a full range of choices in housing types to improve access to affordable housing. The maximum allowable density ranges from 8 to 30 dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the R-3 map symbol see Section 20-22.040. Densities of more than 30 dwellings per acre may be allowed within the Mixed Use land use designation of the General Plan. The R-2 zoning districts implement and are consistent with the Residential Medium Density and Medium High Density land use classifications of the General Plan.
