Bill	California Environmental Quality Act: exemption: junior accessory dwelling units ordinances.	The California Environmental Quality Act (CEQA) requires a lead agency, as defined, to prepare, or cause to be prepared, and certify the completion of an environmental impact report on a project that it proposes to carry out or approve that may have a significant effect on the environment or to adopt a negative declaration if it finds that the project will not have that effect. CEQA also requires a lead agency to prepare a mitigated negative declaration for a project that may have a significant effect on the environment if revisions in the project would avoid or mitigate that effect and there is no substantial evidence that the project, as revised, would have a significant effect on the environment.	us/states/ca	California Legislature	20232024	AB 3057	California AB 3057 (20232024)	bill	California Environmental Quality Act exemption junior accessory dwelling units ordinances	enacted	Wilson	5	22	6	2024-02-16	2024-08-27	openstates	ocd-bill/e5d9d051-cd9a-400e-8a9f-57a94aa66171	http://leginfo.legislature.ca.gov/faces/billNavClient.xhtml?bill_id=202320240AB3057	ce0a23178eca745fa438f31ce27f4b2b741b668962f3930aa605f4e82deae233	2026-07-01	https://data.openstates.org/daily/2026-07-01/public.pgdump	2026-07-06	reported	legislation bill us-ca
