Accessory dwelling units and junior accessory dwelling units.

Existing law, the Planning and Zoning Law, among other things, provides for the creation by ordinance, or by ministerial approval if the local agency has not adopted an ordinance, of an accessory dwelling unit (ADU) or a junior accessory dwelling unit (JADU) in accordance with specified standards and conditions. Existing law defines the term "junior accessory dwelling unit" for these purposes to mean a unit that is no more than 500 square feet in size and contained entirely within a single-family structure.
