Land use: accessory dwelling units.

The Planning and Zoning Law authorizes a local agency to provide by ordinance for the creation of accessory dwelling units in single-family and multifamily residential zones, requires that ordinance to designate areas where accessory dwelling units may be permitted, and sets forth standards the ordinance is required to impose, including, among others, maximum unit size, parking, and height standards. Existing law requires a local agency to submit an ordinance adopted for the creation of accessory dwelling units to the Department of Housing and Community Development and authorizes the department to review and comment on the ordinance. Existing law requires an application for an accessory dwelling unit permit to be considered, as specified, within 120 days of receiving it. This bill would require the ordinance for the creation of accessory dwelling units to designate areas where accessory dwelling units may be excluded for health and safety purposes, as specified. The bill would revise the standards for the local ordinance to, among other things, delete the authority to include lot coverage standards, and include a prohibition on considering the square footage of a proposed accessory dwelling unit when calculating an allowable floor-to-area ratio or lot coverage ratio for the lot. The bill would require that a permit application for an accessory dwelling unit be approved or disapproved within 60 days and would specify that if a local agency does not act on an application for a accessory dwelling unit within 60 days, then the application shall be deemed approved. The bill would prohibit a local agency from requiring that offstreet parking spaces be replaced when a garage, carport, or covered parking structure is demolished or converted in conjunction with the construction of an accessory dwelling unit. The bill would prohibit another local ordinance, policy, or regulation from being the basis for the delay of the issuance of a building permit or use permit for an accessory dwelling unit. The bill would delete provisions authorizing a local agency to require owner occupancy by the permit applicant and would declare an agreement with a local agency to maintain owner occupancy as void and unenforceable. The bill would authorize the department, upon submission of an adopted ordinance for the creation of accessory dwelling units, to submit written findings to the local agency regarding whether the ordinance complies with statutory provisions. The bill would authorize the department to adopt guidelines to implement uniform standards or criteria to supplement or clarify the terms, references, or standards set forth in statute and would exempt the adoption of those guidelines from the Administrative Procedure Act. The bill would, until January 1, 2029, also require a local building official, upon request of the owner of the accessory dwelling unit, to approve a delay of not less than 10 years of the enforcement of any building code requirement that, in the judgment of the building official, is not necessary to protect public health and safety. By increasing the duties of local agencies with respect to land use regulations, the bill would impose a state-mandated local program. This bill would also require the department to notify the city, county, or city and county and authorize notice to the Attorney General when the city, county, or city and county is not substantially complying with the above-described provisions regarding accessory dwelling units. The bill would require a local agency to ministerially approve an application for a building permit to create one or more accessory dwelling units if certain criteria are met. Existing law authorizes a local agency to provide by ordinance for the creation of junior accessory dwelling units, as defined, in single-family residential zones and requires the ordinance to include, among other things, standards for the creation of a junior accessory dwelling unit, required deed restrictions, and occupancy requirements. Existing law prohibits an ordinance from requiring, as a condition of granting a permit for a junior accessory dwelling unit, additional parking requirements. The bill would require a local agency to ministerially approve the creation of junior accessory dwelling units in single-family residential zones, if specified criteria are met. 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.
