No attorney or CPA has reviewed this guide. It is general information, and I can't give legal, tax, lending or financial advice. Rules change and differ by parcel, so check with the City and your own attorney and CPA before you act on anything here.
How the area is laid out
Corona del Mar is part of the City of Newport Beach. State coastal rules add a second layer in the Coastal Zone.
City staff call 30 by 118 feet a typical Corona del Mar lot. Those lots line the old street grid locals call the flower streets.
To see where a lot sits, start with the City's Coastal Zoning Map and parcel map. Then confirm each parcel with the City.
What you can build
The City's zoning code and coastal code both shape what you can build. Lot size, height limits and setbacks, the yards left open around a home, vary across the area. A bluff-side lot can have tighter limits.
The City's FAQ describes a Categorical Exclusion that can let some projects skip a coastal permit, with conditions.
Ask a City planner at 949-644-3204 about a parcel, including any bluff limits and that exclusion. Ask a real estate attorney about covenants.
What a small older lot can become
Older cottages can be nonconforming, or short of today's parking and other rules. That can limit how much you can add. The City has a Cottage Preservation exception, so ask a planner what your lot can become.
Places to know
Corona del Mar State Beach is a half-mile of sand at 3001 Ocean Boulevard.
Little Corona is a small sandy cove with rocky reefs at Ocean Boulevard and Poppy. State rules ban taking any living thing from its tidepools.
Sherman Library and Gardens is a nonprofit botanical garden and history research library at 2647 East Coast Highway.
Five questions before you write an offer
- Which rulebook governs this parcel? Ask the City for its zoning, its Setback Map and its floor area limit.
- Is the lot in the Coastal Zone, and can it use the Categorical Exclusion?
- Is the lot on a bluff? Ask the City if a Bluff Overlay applies and what it leaves you to build.
- Is the home nonconforming on parking, and did anyone record a cottage deed restriction?
- What legally protects the view you are paying for? City code may not protect a private view. Read the CC&Rs, the recorded rules that bind a lot, and ask a real estate attorney.
Three things to prepare before you list
- Find your lot records, including any covenant (a recorded promise) holding lots together and any condo map.
- Check that your permits add up to the floor area you have today. The City's Residential Building Report can show permit history and zoning.
- Walk the public right-of-way past your property line. Planters, walls and patio items there can need City approval, so check before you list.
