HOA and Coastal Commission approval for Orange County remodels

HOA architectural review

California associations run under the Davis-Stirling Common Interest Development Act, which starts at Civil Code section 4000. Whether you need approval depends on the governing documents, usually the CC&Rs (covenants, conditions and restrictions, the association's recorded rules): a change to the exterior appearance of your home has to follow them (section 4760). When they require approval, section 4765 sets the ground rules:

• A fair, reasonable and expeditious written procedure, with a stated maximum time to respond.
• Decisions in good faith, not unreasonable, arbitrary or capricious, and within the law, including fair housing law and the building code.
• A written decision. A denial has to explain why and how to ask the board to reconsider, and you are entitled to that reconsideration at an open board meeting, unless the board itself decided at an open meeting.
• A yearly notice to members of which changes need approval, with a copy of the procedure.

Find that annual notice or ask the management company for the procedure, then submit complete plans.

What an HOA cannot block outright

For these projects, state law voids association rules that effectively prohibit or unreasonably restrict them, though reasonable design and placement rules still apply.

• ADUs (accessory dwelling units) and junior ADUs on a single-family lot (Civil Code sections 4751 and 714.3). A reasonable restriction cannot include fees or other financial requirements, and the state housing department's (HCD) ADU Handbook counts an HOA review that runs past the 60 days a city gets as an effective prohibition. See garage conversion vs ADU.
• Solar (Civil Code section 714). A solar application not denied in writing within 45 days is deemed approved, unless the association asked for more information. Our solar and battery guide covers the cost and efficiency limits on a restriction.
• EV charging in your unit or designated parking space (Civil Code section 4745). The same rule applies, with 60 days instead of 45.

Replacing a roof in an HOA

A new roof goes through the same review as any exterior change. Two more rules apply:

• Who replaces it. Unless your CC&Rs say otherwise, the association repairs and replaces the common area and each owner takes care of their own unit or lot (Civil Code section 4775). Whether the roof is common area depends on how the CC&Rs and any condo plan draw the line (sections 4125 and 4185), so check them before you get bids.
• Fire-rated roofing. An association cannot require a roof that breaks the state fire-retardant roofing law (Civil Code section 4720). That law, Health and Safety Code section 13132.7, sets a minimum fire rating for any roofing put on in a repair, and for the whole roof once more than half of it is replaced within a year: Class C in most places. In a very high fire hazard severity zone it is Class A, or Class B if the city has adopted the State Fire Marshal's model ordinance, and the governing documents must allow at least one roof covering that meets it. Ask the building department which class applies to your address.

Costs and city permits are in the roof replacement guide.

The coastal zone and the Coastal Act

Under the California Coastal Act, anyone doing "development" in the coastal zone needs a coastal development permit, in addition to every other permit the work needs (Public Resources Code section 30600). Development is defined broadly in section 30106: building, demolition, grading, and any change to the size of a structure all count.

To see whether your lot is in or near the coastal zone, start with the Coastal Commission's boundary maps. The Commission warns that its digital maps do not replace a formal boundary determination, so if your lot is close to the line, ask the city.

Who issues the coastal permit in each city

Each coastal city writes a local coastal program. Once the Commission certifies it, the city issues most coastal permits itself (section 30519). Where there is no certified program, you apply to the Commission. The Commission's October 2024 status chart lists these Orange County cities with land in the coastal zone:

• Seal Beach

  No certified program. The Coastal Commission issues coastal permits; a May 2026 Commission staff report on a Seal Beach home addition says so.

• Huntington Beach

  Certified 1985. The Sunset Beach annexation and a few other areas are listed as uncertified.

• Newport Beach

  Certified, effective January 30, 2017. The city issues most coastal permits; Banning Ranch and the Newport Coast annexation are listed as uncertified.

• Irvine

  Certified 1982 for the part of the city in the coastal zone.

• Laguna Beach

  Certified 1993. Three Arch Bay, Blue Lagoon, Irvine Cove and Hobo Canyon are listed as areas where the city's program is not certified.

• Laguna Niguel

  Certified 1990.

• Dana Point

  Certified 1989.

• San Clemente

  Land use plan certified August 10, 2018, but the implementation plan is still in progress, so the city does not have a fully certified program yet.

The chart also lists unincorporated county areas and a few other cities. Even in a certified city, the Commission keeps permit authority over tidelands and submerged land, and a city's approval can be appealed to the Commission in certain areas near the shore, such as between the sea and the first public road or within 300 feet of a beach or of the top of a coastal bluff (section 30603).

What usually needs a coastal permit, and what is exempt

Public Resources Code section 30610 exempts improvements to an existing single-family home, and repair or maintenance that does not enlarge anything. The Commission's regulation (California Code of Regulations title 14 section 13250) lists the improvements that still need one, among them:

• Any improvement if the home is on a beach, in a wetland, seaward of the mean high tide line, in an environmentally sensitive habitat area, in an area designated highly scenic, or within 50 feet of the edge of a coastal bluff.
• On lots between the sea and the first public road, or within 300 feet of a beach, an addition of 10 percent or more of the floor area, a height increase of more than 10 percent, or a significant detached structure such as a garage, fence or shoreline protection.
• Any improvement where the original permit for the house said future improvements would need one.

The same regulation counts garages, pools, fences and sheds as part of the home, but not guest houses or self-contained residential units, so an ADU is not covered by the single-family exemption.

Your city's program can go further. Newport Beach, for example, says its categorical exclusion takes single-unit and two-unit projects out of the coastal permit requirement, except on the first row of lots on the shoreline and in the Bay Shores community. Interior remodels such as a kitchen or bathroom that do not add floor area or height are usually the easy case, but the city makes the call for your lot.

ADUs in the coastal zone: the 60-day clock

AB 462, signed October 10, 2025 and effective immediately, amended Government Code section 66329:

• A city with a certified program must approve or deny the coastal permit for an ADU within 60 days of a complete application, at the same time as its own ADU review and without a public hearing.
• The city's decision on an ADU coastal permit cannot be appealed to the Coastal Commission under section 30603.
• Where there is no certified program, as in Seal Beach and San Clemente, the Commission gets the same 60 days, or the application is deemed approved. The exception: if the ADU is filed together with a new house, the Commission can decide the house first.

The rest of the 2026 ADU rules are in our ADU cost guide.

Getting both approvals

Design to satisfy both: a change the HOA asks for can change what the city reviews, and the reverse. Keep every decision in writing with your building permit records, and put in your contract who is responsible for which approval. Our deposit rules guide covers what the contract must say.
