Development inside the coastal zone is defined broadly: new construction, additions, demolition, exterior remodels, grading, vegetation removal, and some landscape changes. Every coastal city in San Diego County has a certified Local Coastal Program, so the local city issues most CDPs. The California Coastal Commission issues the permit directly on tidelands, submerged lands, and mapped Commission jurisdiction.
When do you need a CDP?
| Jurisdiction | CDP required? | Key notes |
|---|---|---|
| City of San Diego (Coastal Overlay) | Yes | Appealable and non-appealable areas |
| Oceanside, Carlsbad, Encinitas, Imperial Beach | Yes, on coastal parcels | Certified LCP; local review with appeal path |
| Del Mar and Solana Beach | Yes, citywide | Every parcel is in the coastal zone |
| Port of San Diego tidelands | Yes — Port CDP | Port is the CDP authority on bay tidelands |
How long does a coastal permit take?
Straightforward residential projects in a certified LCP city typically take 3–7 months for a local CDP. Commission-issued or appealed projects commonly take 8–18 months. Filing fees are often $500–$3,000-plus locally. Coastal-specific exhibits — biological survey, ESHA, geotechnical bluff setback — commonly run $5,000–$25,000 combined. Public view analysis and staking add another $2,000–$6,000.
Under AB 462, cities with a certified LCP must approve or deny a CDP for an ADU within 60 days of a complete application. Missing coastal exhibits (view analysis, bluff setback, ESHA) is the usual reason a package sits for months.
Appealable vs. non-appealable jurisdiction
Under Public Resources Code §30603, appealable areas include land between the sea and the first public road; within 300 feet of a beach, mean high tide, or coastal bluff edge; and within 100 feet of a wetland, estuary, or stream. An appeal must be filed within 10 business days of the Commission receiving a Notice of Final Action. A substantial-issue finding restarts review at the state level and can add three to twelve months.
Nalu Architecture Inc. designs to LCP standards before the first submittal and puts coastal exhibits in the first package. We create a road map for permitting. We do not claim first-cycle approval.

Questions we hear
Do I need a Coastal Development Permit in Encinitas or Del Mar?
Most development on Encinitas coastal parcels needs a CDP issued by the City under its certified LCP. Del Mar is entirely inside the coastal zone, so every parcel needs coastal review. Appealable locations near the beach, bluff, or first public road can still be appealed to the California Coastal Commission.
How long does a San Diego County CDP take in 2026?
A straightforward local CDP is typically 3–7 months. Projects inside Coastal Commission permit jurisdiction, or projects that are appealed, commonly take 8–18 months. ADU CDPs in certified LCP cities have a 60-day clock under AB 462 once the application is complete.
