Bill	Alquist-Priolo Earthquake Fault Zoning Act: exemptions.	Under the Alquist-Priolo Earthquake Fault Zoning Act, before approving a project within an earthquake fault zone, a city or county is directed to require the preparation of a geologic report, subject to certain exceptions. Existing law exempts from this requirement the conversion of an existing apartment complex into a condominium, projects for the alteration or addition of any structure if the value of the alteration or addition does not exceed 50% of the value of the structure, and certain projects for alterations that include seismic retrofitting if a city or county, among other things, requires certain seismic retrofitting and prohibits an increase in human occupancy load.	us/states/ca	California Legislature	20232024	AB 1046	California AB 1046 (20232024)	bill	Alquist-Priolo Earthquake Fault Zoning Act exemptions	enacted	Lowenthal	7	22	6	2023-02-15	2023-10-13	openstates	ocd-bill/0caf2089-1681-4960-b3ea-1e289dadb8e0	http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202320240AB1046	348886efe352bb83dde5ab92079e66ee9082dea130f087559b05cca6baaa49c8	2026-07-01	https://data.openstates.org/daily/2026-07-01/public.pgdump	2026-07-06	reported	legislation bill us-ca
