What is a coastal commission permit?

The California Coastal Act of 1976 created the Coastal Commission and the Coastal Zone. The Coastal Zone extends approximately 1,000 yards inland from mean high tide (larger in some areas) and covers most of the California coast from Oregon to Mexico.

When a Coastal Development Permit is required:

Almost any development in the Coastal Zone requires a CDP, including:

• New construction.
• Most additions and remodels (even cosmetic work in some jurisdictions).
• Demolitions.
• Grading.
• Paving.
• Removal of major vegetation.
• Changes in the intensity of use of land or water.

Two CDP paths:

1. Local government CDP — 63 California coastal jurisdictions have a certified Local Coastal Program (LCP). Residents apply to the local planning department; the local agency issues the CDP subject to Coastal Commission appeal rights.
2. Coastal Commission CDP — for areas without a certified LCP, or for specific "appeal areas" within LCP jurisdictions, the Coastal Commission itself reviews and issues the permit.

What the review covers:

• Public access — development cannot block existing coastal access; projects may be required to dedicate lateral access easements along the beach.
• Habitat — Environmentally Sensitive Habitat Areas (ESHA), wetlands, and sensitive species trigger deeper review.
• Viewshed — blue-water views from public areas must be preserved.
• Hazards — sea-level rise, erosion, and bluff stability over a 75-year lifespan.
• Archaeological resources — tribal consultation may be required.

Typical timeline and cost:

• Straightforward remodel in LCP jurisdiction: 3-6 months, $3,000-$8,000 permit fee.
• New single-family or significant addition: 6-12 months, $10,000-$50,000 in planning/permit/consultant soft costs.
• Appeal-area projects: 12-24 months.
• Wetlands or ESHA projects: can extend 2-4 years.

LA coastal overlay: Venice, Pacific Palisades, and parts of Santa Monica sit in the Coastal Zone. Projects go through LA City Planning and can be appealed to the Coastal Commission.

AskBaily's California coastal scoping flags Coastal Zone overlay early and routes to contractors with coastal permit experience. Coastal projects are not good fits for first-time homeowners expecting a 4-month remodel.
