		<ns0:DigestText>
			<html:p>Existing law provides for the creation by local ordinance, or by ministerial approval if a local agency has not adopted an ordinance, of accessory dwelling units in areas zoned for single-family or multifamily dwelling residential use in accordance with specified standards and conditions. Existing law prohibits a local agency from issuing a certificate of occupancy for an accessory dwelling unit before the local agency issues a certificate of occupancy for the primary dwelling.</html:p>
			<html:p>This bill, notwithstanding that prohibition, would require a local agency to issue a certificate of occupancy for an accessory dwelling unit constructed in a county that is subject to a proclamation of a state of emergency made by the Governor on or after February 1, 2025, even if the primary dwelling has not yet been issued a certificate of occupancy, if certain
			 requirements are met, including that the primary dwelling was substantially damaged or destroyed by an event referenced in the state of emergency proclamation. By imposing new duties on local agencies, the bill would impose a state-mandated local program.</html:p>
			<html:p>Existing law requires a permitting agency to either approve or deny an application to create or serve an accessory dwelling unit within 60 days from the date the permitting agency receives a completed application if there is an existing single-family or multifamily dwelling on the lot. Existing law deems the application approved if the local agency has not approved or denied the completed application within 60 days. Under existing law, if the permit application to create or serve an accessory dwelling unit is submitted with a permit application to create or serve a new single-family or multifamily dwelling on
			 the lot, the permitting agency may delay approving or denying the permit application for the accessory dwelling unit until the permitting agency approves or denies the permit application to create or serve the new single-family or multifamily dwelling, as provided.</html:p>
			<html:p>The California Coastal Act of 1976, which is administered by the California Coastal Commission, requires any person wishing to perform or undertake any development in the coastal zone, as defined, to obtain a coastal development permit from a local government or the commission, except as provided. Existing law specifies that the laws governing accessory dwelling units do not supersede or in any way alter or lessen the effect or application of the act, except as specified.</html:p>
			<html:p>This bill would create an exception to the above provision by requiring a local government or the commission, as specified, to either approve or deny a coastal development permit application for an accessory dwelling unit within 60 days of receiving a completed application. The bill would, notwithstanding that 60-day time limit, authorize the commission, if a coastal development permit application to create or serve an accessory dwelling unit is submitted with a coastal development permit application to create or serve a new single-family or multifamily dwelling on the lot, to delay approving or denying the coastal development permit application for the accessory dwelling unit until the commission approves or denies the coastal development permit application to create or serve the new single-family or multifamily dwelling. Under the bill, and except under the circumstance described above, if the commission has not approved or denied a completed application within 60
			 days, the application would be deemed approved.</html:p>
			<html:p>The bill would include findings that changes proposed by this bill address a matter of statewide concern rather than a municipal affair and, therefore, apply to all cities, including charter cities.</html:p>
			<html:p>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.</html:p>
			<html:p>This bill would provide that no reimbursement is required by this act for a specified reason.</html:p>
			<html:p>This bill would declare that it is to take effect immediately as an urgency statute.</html:p>

				<html:p>The Legislature finds and declares all of the following:</html:p>
				<html:p>
					(a)
					<html:span class="EnSpace"/>
					The state faces a housing crisis of availability and affordability, in large part due to a severe shortage of housing.
				</html:p>
				<html:p>
					(b)
					<html:span class="EnSpace"/>
					Solving the housing crisis therefore requires a multifaceted, statewide approach which will include, but is not limited to, any or some of the following:
				</html:p>
				<html:p>
					(1)
					<html:span class="EnSpace"/>
					Encouraging an increase in the overall supply of housing.
				</html:p>
				<html:p>
					(2)
					<html:span class="EnSpace"/>
					Encouraging the development of housing that is affordable to
				households at all income levels.
				</html:p>
				<html:p>
					(3)
					<html:span class="EnSpace"/>
					Removing barriers to housing production.
				</html:p>
				<html:p>
					(4)
					<html:span class="EnSpace"/>
					Expanding the availability of rental housing.
				</html:p>
				<html:p> Therefore, addressing the housing crisis and the severe shortage of housing is a matter of statewide concern and is not a municipal affair as that term is used in Section 5 of Article XI of the California Constitution. Therefore, Sections 1 and 2 of this act amending Sections 66328 and 66329 of the Government Code apply to all cities, including charter cities.</html:p>

Last Version Text Digest Existing law provides for the creation by local ordinance, or by ministerial approval if a local agency has not adopted an ordinance, of accessory dwelling units in areas zoned for single-family or multifamily dwelling residential use in accordance with specified standards and conditions. Existing law prohibits a local agency from issuing a certificate of occupancy for an accessory dwelling unit before the local agency issues a certificate of occupancy for the primary dwelling. Existing law requires a permitting agency to either approve or deny an application to create or serve an accessory dwelling unit within 60 days from the date the permitting agency receives a completed application if there is an existing single-family or multifamily dwelling on the lot. Existing law deems the application approved if the local agency has not approved or denied the completed application within 60 days. Under existing law, if the permit application to create or serve an accessory dwelling unit is submitted with a permit application to create or serve a new single-family or multifamily dwelling on the lot, the permitting agency may delay approving or denying the permit application for the accessory dwelling unit until the permitting agency approves or denies the permit application to create or serve the new single-family or multifamily dwelling, as provided. The California Coastal Act of 1976, which is administered by the California Coastal Commission, requires any person wishing to perform or undertake any development in the coastal zone, as defined, to obtain a coastal development permit from a local government or the commission, except as provided. Existing law specifies that the laws governing accessory dwelling units do not supersede or in any way alter or lessen the effect or application of the act, except as specified. This bill would create an exception to the above provision by requiring a local government or the commission, as specified, to either approve or deny a coastal development permit application for an accessory dwelling unit within 60 days of receiving a completed application. The bill would, notwithstanding that 60-day time limit, authorize the commission, if a coastal development permit application to create or serve an accessory dwelling unit is submitted with a coastal development permit application to create or serve a new single-family or multifamily dwelling on the lot, to delay approving or denying the coastal development permit application for the accessory dwelling unit until the commission approves or denies the coastal development permit application to create or serve the new single-family or multifamily dwelling. Under the bill, and except under the circumstance described above, if the commission has not approved or denied a completed application within 60 days, the application would be deemed approved. The bill would include findings that changes proposed by this bill address a matter of statewide concern rather than a municipal affair and, therefore, apply to all cities, including charter cities. This bill would declare that it is to take effect immediately as an urgency statute.
