WEST END
Single-Family Residential - 6,000 sq ft - Historic Combining District
The R-1 zoning district is applied to areas of the City intended to be maintained as residential neighborhoods comprised of detached and attached single-family houses, clustered Residential hillside projects, and small multi-family projects, together with compatible accessory uses. The maximum allowable density ranges from 2 to 13 dwellings per acre, with the specific allowable density for each parcel shown on the zoning map by a numerical suffix to the R-1 map symbol see Section 20-22.040. The R-1 zoning district implements and is consistent with the Residential Very Low Density where residential clustered on hillsides is desirable, Low Density or Open Space, Low Density, and Medium Low Density land use classifications of the General Plan. The H combining district is intended to recognize, preserve, and enhance Santa Rosa's locally designated historic resources.
