Accessory and junior accessory dwelling units are a valuable form of housing in the city. These units meet the city's general plan housing policies related to: attaining a variety of housing types; providing housing stock to lower income households; including lower income housing units within market rate housing projects; providing alternative, nontraditional means suited to the community to fill lower and moderate income housing needs; meeting the city's share of regional housing needs; providing a means to assist homeowners in financing the acquisition of a home; and providing security to homeowners living alone.
The further purpose of this chapter is to comply with the requirements of state law. To do so, this chapter identifies those zoning districts where an accessory dwelling unit or junior accessory dwelling unit meeting enumerated standards to ensure neighborhood compatibility is a permitted use in that district.
