Coastal Development Permit (CDP)
Permit required for construction inside California's Coastal Zone, issued by the city or the California Coastal Commission.
Any construction inside the Coastal Zone — generally west of Lincoln Blvd in Venice, the entire Marina Peninsula, Pacific Palisades, and similar coastal strips — requires a Coastal Development Permit on top of the standard building permit. Inside the City of LA, ministerial CDPs are issued by LADBS West LA; appealable CDPs go to the California Coastal Commission.
A CDP review adds 8–16 weeks to the standard timeline and may require an environmental study if the lot is undeveloped or near sensitive habitat. Most ADUs in the Coastal Zone qualify for the streamlined Coastal Exclusion if they meet specific size and height limits.
