The purpose of the accessory dwelling unit chapter is to comply with state law. The chapter provides for accessory dwelling units in certain areas and on lots developed or proposed to be developed with single-family or multifamily dwellings. These structures are accessory and incidental to a dwelling on the same lot. (Gov. Code, § 65852.2(j)(2).) Such accessory dwellings are allowed because they can contribute needed housing to the community's housing stock. Accessory dwelling units provide housing for family members, students, the elderly, in-home health care providers, the disabled, renters, and homeowners who create accessory dwelling units. In addition, the chapter provides a mechanism to grant legal status to existing illegally constructed accessory units in single family neighborhoods. By encouraging legalization, safe dwellings may be added to the city's existing housing supply.
