Single-Family Residential District
This district implements the single-family residential category of the General Plan and applies to areas intended to develop into a single-family detached unit pattern. RS areas typically include custom home subdivisions on hillsides or constrained sites, and post war tract subdivisions, which usually have uniform platting patterns, setbacks and building types. This district provides opportunities for low density detached single-family homes, accessory dwelling units, clustered and planned developments, mobile homes, manufactured housing and compatible uses such as day care and smaller residential care facilities. Bed and breakfast inns, and public and quasi-public uses may also be allowed in appropriate locations at the discretion of the city.
