In relation to the City's process for reviewing applications to legalize unpermitted ADUs constructed prior to 2020, California Amendment Bill 2533 (AB 2533) prohibits cities from denying an ADU application solely based on non-compliance with current building code provisions, provided the structure is not otherwise substandard.
AB 2533 does not preclude the City from requesting construction drawings or other pertinent information to document any failures to meet building code provisions and facilitate a comprehensive review for the issuance of a Certificate of Occupancy. While the City cannot deny an application solely for building code violations, the City retains the authority to request information in accordance with building code requirements. The City may request construction documents and other drawings pursuant to Building Code Section 105.3 for the consideration of such applications.
