The Planning and Zoning Law, among other things, provides for the creation of accessory dwelling units by local ordinance, or, if a local agency has not adopted an ordinance, by ministerial approval, in accordance with specified standards and conditions. Existing law prohibits a local agency from imposing parking standards for an accessory dwelling unit under certain circumstances, whether or not the local agency has adopted a local ordinance pursuant to the above provisions. Under existing law, those circumstances include, among others, if the accessory dwelling unit is located within 12 of one mile walking distance of public transit or there is a car share vehicle located within one block of the accessory dwelling unit.
This bill would additionally prohibit a local agency from imposing any parking standards if the accessory dwelling unit is 500 square feet or smaller.
Existing law also provides for the creation of junior accessory dwelling units by local ordinance, or, if a local agency has not adopted an ordinance, by ministerial approval, 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 owner-occupancy in the single-family residence in which the junior accessory dwelling unit is permitted.
Under this bill, that owner-occupancy requirement would apply only if the junior accessory dwelling unit has shared sanitation facilities 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 accessory dwelling units and 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.
