RS-7
Single-Family Residential Zone
The RS zone is applied to areas of the City appropriate for single-family residential land uses in neighborhoods at a density of three to six units per net acre, subject to appropriate standards. The specific allowable density for each parcel is shown on the Zoning Map by a numerical suffix residential density designator (see Section D2-8). Minimum lot size for new parcels ranges from 3,500 to 12,000 sq ft. Depending upon the applicable residential density designator, the RS zone is consistent with and implements the Single Family Low Density, Single Family Low-Medium Density, and Single Family Medium Density land use classifications of the General Plan.
