Residential Single-Family Zone
The General Plan designates residential land use classifications intended to accommodate various densities of residential development within the city. It is the intent of every residential zone established in this title to implement these goals and objectives. The various residential zones contain development standards intended to achieve General Plan goals and objectives by regulating residential development within specific density ranges. No residential subdivision or residential development shall be authorized which exceeds the density provisions of the underlying General Plan land use classification. See Chapter 17.220 for density bonus regulations related to affordable housing projects.; For the purpose of this title, residential density is expressed as dwelling units per sq ft of net lot area. However, it may also be expressed as dwelling units per acre of net lot area. Net lot area is calculated by subtracting all portions of the lot, or lots, which have been proposed to be dedicated for public rights-of-way.
