San Diego County Coastal Zone Property Records: Permits and Local Coastal Programs

Much of San Diego County’s coastline lies inside cities, and each of them handles Coastal Zone permits a little differently. Whether a home is in the Coastal Zone, and whether the local government has a certified Local Coastal Program, decides who reviews work on the property and which records a buyer should request. This guide explains how to check both and what the resulting records do and do not show about an existing home.

What the Coastal Zone designation does

Under the California Coastal Act, development in the Coastal Zone generally cannot begin until a coastal development permit has been issued. The Coastal Commission defines development broadly, so it can include changes in the intensity of use as well as construction. Some work qualifies for an exemption, but the Commission describes the exceptions as narrow and offers a written exemption request form.

The official Coastal Zone boundary is set by maps the Commission adopted in 1977. The Commission’s boundary map page explains that its digital boundary files are a copy, not the adopted maps, and may not remove the need for a formal boundary determination. For a parcel near the line, ask the city or the Commission district office for a determination rather than relying on an online map.

Who issues coastal permits: certified Local Coastal Programs

A Local Coastal Program is a city’s or county’s land use plan and implementing ordinances for its coastal area. Once the Commission certifies it, the local government issues most coastal development permits, while the Commission keeps certain permit and appeal jurisdiction and must certify amendments. Where no certified program exists, applicants go to the Commission. In the Port of San Diego, the port’s governing body issues similar permits under a certified port master plan.

The County’s own Local Coastal Program covers about two square miles of unincorporated coastal land in the San Dieguito community. The Commission certified it in February 2021, and the County took over coastal permitting there in March 2021.

Certification status by jurisdiction

The Commission’s LCP status summary chart, dated October 2024 (fiscal year 2023-24), is the most recent statewide status chart linked from its LCP information page. For San Diego County coastal jurisdictions it shows the following. Status can change after the chart date, so confirm with the city before relying on it.

Jurisdiction Status shown on the FY 23-24 chart What to request for a property
Oceanside Effectively certified City coastal permits for the home and any shoreline work
Carlsbad Certified in several segments; the Agua Hedionda segment and some deferred areas are listed without a certified LCP Confirm which segment the parcel is in and whether the city or Commission issued permits
Encinitas Effectively certified City coastal permits; bluff and shoreline permit conditions where relevant
Solana Beach Listed without a certified LCP Commission permit records as well as city records
Del Mar Effectively certified City coastal permits and permit conditions
City of San Diego Certified in most segments; the Mission Bay segment and several deferred areas are listed without a certified LCP Confirm the segment; check both city and Commission records
Coronado Effectively certified City coastal permits
Imperial Beach Effectively certified City coastal permits; shoreline protection records where relevant
National City Effectively certified City coastal permits
Chula Vista Effectively certified City coastal permits
Unincorporated County (San Dieguito area) Effectively certified, 2021 County coastal permits through Planning & Development Services

Even where a city issues permits, some decisions can be appealed to the Commission, and permits issued before certification may have been issued by the Commission. For an older home, both offices can hold relevant records.

Remodels and additions in the Coastal Zone

Plans for a remodel, addition, ADU or landscape change on a coastal parcel should start with the agency that issues coastal permits for that segment. Requirements can differ from inland parts of the same city, and the coastal process can run alongside ordinary building permits. A neighbor’s approved project shows what was allowed on that parcel under its conditions; it is not an approval for the property being bought. See also our guide to buying a home with an ADU.

Using coastal records in a purchase or sale

For buyers, the permit file explains what the current home is allowed to be and what obligations came with it. For sellers, assembling the coastal permits, recorded conditions and shoreline records before listing answers questions that would otherwise surface during escrow. Disclosure duties still apply; the seller disclosures guide and the natural hazard disclosure report cover the general framework.
