CA AB1633

Expands the Housing Accountability Act until January 1, 2031 to define local agency failure to make CEQA exemption determinations or abuse of discretion as "disapproving" a housing development project for projects meeting specific criteria (15+ dwelling units per acre, located in urbanized areas, and meeting transit/amenity/urban proximity requirements).

Requires local agencies to adopt negative declarations, environmental impact reports, or comparable CEQA documents within specified timeframes for qualifying projects; failure to do so constitutes disapproval under the Housing Accountability Act.

Establishes procedures allowing applicants to provide written notice to local agencies about CEQA compliance, triggering 90-day determination deadlines with 90-day extension possibilities; applicant's notice must include evidence supporting exemption eligibility.

Applies only to housing projects not located in very high fire hazard severity zones or certain sensitive sites specified in existing law, and requires projects to demonstrate substantial evidence of CEQA exemption eligibility.

Maintains existing Housing Accountability Act enforcement mechanisms including court orders, fines of at least $10,000 per unit for non-compliance, and attorney's fees awards; all new CEQA-related provisions expire January 1, 2031.
