Corona del Mar is a coastal neighborhood of the City of Newport Beach, and the city’s Local Coastal Program requires a Coastal Development Permit for development in the coastal zone unless an exemption applies. This guide explains how Newport Beach permit and coastal rules apply to a Corona del Mar home and what to check before selling.

Who governs a Corona del Mar home

Corona del Mar has no city government of its own. The City of Newport Beach issues building permits, inspects work and handles zoning and code enforcement, and the city’s land use plan lists Corona del Mar as a coastal neighborhood. Our building permits guide, code enforcement guide and zoning and ADU guide cover the citywide rules.

Building permits

The city says a building permit is needed for new construction, water heater replacement and similar work. Its guidance asks for two sets of 18 by 24 inch plot plans, lists plan submittal at (949) 718-1888 and inspections at (949) 644-3255, and names fences 3.5 feet or lower and platforms or decks at or below 30 inches as exempt items. Confirm the current rules with the city before you build.

The coastal zone and Coastal Development Permits

The city’s Local Coastal Program requires a Coastal Development Permit for development in the coastal zone. Exemptions apply for some improvements and for repair and maintenance, and a Categorical Exclusion order covers some single-family and duplex projects, except next to beaches, the harbor or bluffs.

The city can issue these permits, and the Coastal Commission hears appeals. Appeal areas include land between the sea and the first public road, within 300 feet of a beach or bluff, and within 100 feet of streams or wetlands. For planning questions the city lists a planner line at (949) 644-3204.

For Corona del Mar owners near the bluffs or beaches, that means an exterior project can need more review than the same project inland, and a past addition built without the right permit is a resale problem.

Code enforcement and unpermitted work

Work done without permits can surface through a complaint, a sale inspection or a records check. Our statewide as-is guide explains disclosure, and the seller closing costs guide covers what comes out of proceeds.

What to check before selling

Request the city’s permit history for the address.
Ask whether the parcel is in the coastal zone, an appeal area or a bluff area.
Find any Coastal Development Permit or exemption for past work.
List any patio, deck, addition or finished space without a permit.
Compare legalization cost and time with an as-is sale.
