Marin County's coastal areas are regulated by the Local Coastal Program (LCP) Implementation Plan, codified in Title 20 of the Marin County Code. Development within the Coastal Zone — including West Marin and Bay shoreline — requires a Coastal Permit. BCDC also regulates within 100 feet of the Bay shoreline.
Title 20 of the Marin County Code implements the Local Coastal Program for the Marin County Coastal Zone, covering West Marin towns from Muir Beach through Tomales and parts of Point Reyes. The LCP regulates development, vegetation removal, grading, and shoreline armoring; a Coastal Permit is required for most projects. Separately, the San Francisco Bay Conservation and Development Commission (BCDC) has permit jurisdiction within 100 feet of the Bay shoreline along eastern Marin. BCDC adopted the Regional Shoreline Adaptation Plan in December 2024 under SB 272, and Marin must complete a local sea-level-rise plan approved by BCDC by 2034.
Construction in the Coastal Zone without a Coastal Permit violates Title 20 and is enforced by CDA with stop-work orders and restoration. BCDC adds civil penalties up to $30,000 per violation for unauthorized Bay shoreline work.
