AB 1154, Carrillo. Junior accessory dwelling units.
The Planning and Zoning La w, among other things, pro vides for the creation of
junior accessory dwelling units by local ordinance, or , if a local agency has not adopted an ordinance, by ministerial appro val, in accordance with specified standards and conditions. Existing law requires an ordinance that provides for the creation of a junior accessory dwelling unit to, among other things, require o wner-occupancy in the single-f amily residence in which the junior accessory dwelling unit is permitted.
Under this bill, that o wner-occupancy requirement would apply only if the junior accessory dwelling unit has shared sanitation f acilities with the existing structure. The bill would require an ordinance that provides for the creation of a junior accessory dwelling unit to require that a rental of a junior accessory dwelling unit be for a term longer than 30 days.
By imposing new duties on local governments with respect to the approval of junior accessory dwelling units, the bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
The people of the State of California do enact as follows:
SECTION 1. Section 66333 of the Government Code is amended to read:
66333. Notwithstanding Article 2 (commencing with Section 66314), a local agency may, by ordinance, provide for the creation of junior accessory dwelling units in single-family residential zones. The ordinance may require a permit to be obtained for the creation of a junior accessory dwelling unit, and shall do all of the following:
