CA AB1804

Exempts residential or mixed-use housing projects in unincorporated county areas from California Environmental Quality Act (CEQA) requirements until January 1, 2025, if specified conditions are met.

Requires projects to be consistent with general plan and zoning designations, contain at least 6 dwelling units with density meeting specified thresholds, and be located on sites of no more than 5 acres substantially surrounded by urban uses.

Prohibits exemption if projects may cause significant effects on transportation, noise, air quality, greenhouse gas emissions, water quality, endangered species habitat, scenic resources on state scenic highways, or historical resources.

Requires lead agencies to file a notice of exemption with the Office of Planning and Research and county clerk if determining a project qualifies for this exemption.

Provides that no state reimbursement is required because local agencies have authority to levy fees or assessments to cover costs of implementing this mandate.
