Wildfire insurance when buying a home in South Orange County

For many South County homes, insurance is now one of the first things to settle, not the last. A buyer who waits until the week before closing can find that the policy they expected is not available, and that the backup costs more and covers less.

This guide covers:

• where the state's fire hazard zones fall from Irvine to San Clemente
• what has happened in the insurance market here
• how the FAIR Plan and its companion policies work
• what sellers must tell you
• when to line up coverage during escrow

Where the fire hazard zones are

The State Fire Marshal maps fire hazard severity zones in three classes: Moderate, High and Very High. The maps measure hazard, based on physical conditions like vegetation, slope and weather over 30 to 50 years. They don't reflect how an individual home has been hardened or recent fuel clearing (OSFM). So a zone on the map doesn't by itself decide whether an insurer will cover a specific home.

New local maps for Orange County cities came out on March 24, 2025, and they expanded the zones compared with the old 2007 maps (City of Lake Forest). The county adopted the map for unincorporated areas in August 2025 (OC Public Works). The chart shows how much of each South County city's land is now in the Very High zone.

The biggest change is in San Juan Capistrano, where the Very High area grew from about 400 acres to more than 2,600. San Clemente and Laguna Niguel also grew substantially. Canyon and ranch land outside the cities, including Coto de Caza, Trabuco Canyon and much of Rancho Mission Viejo, is mapped separately by the state and largely falls in Very High as well (CAL FIRE data).

Zones often split neighborhoods and even streets. Always check the exact address with CAL FIRE's zone lookup.

Recent fires near South County

Several of these fires led to evacuations in South County neighborhoods. The Bond Fire, for example, brought evacuation warnings to Portola Hills in Lake Forest and northern Trabuco Canyon (CAL FIRE).

The Coastal Fire started southeast of Laguna Beach and burned into homes in Laguna Niguel (CAL FIRE). The Airport Fire's structure losses were counted across both Orange and Riverside counties (CAL FIRE).

What has happened to insurance here

When regular insurers decline to write or renew a policy, homeowners turn to the California FAIR Plan, an insurer of last resort run by the property insurers licensed in the state (Department of Insurance). In Orange County, FAIR Plan policies grew from 4,085 in 2021 to 23,748 in 2025 (FAIR Plan). The growth reached well beyond the canyons.

Statewide, FAIR Plan growth has slowed in 2026. The Department of Insurance's Sustainable Insurance Strategy requires insurers that use newer catastrophe models in their rates to write more policies in wildfire-distressed areas (Department of Insurance). As of May 2026, the companies that had committed include Farmers, Mercury, CSAA, USAA, AAA Southern California and Travelers (Department of Insurance).

One detail matters for South County: the state's distressed-area list doesn't include Orange County as a distressed county. Only two Orange County ZIP codes appear on the list, 92676 and 92678 in the canyon areas (March 2025 list). So those writing commitments are aimed mostly at other parts of the state.

How the FAIR Plan works, and what it doesn't cover

A FAIR Plan dwelling policy is a named-peril policy. It covers fire and lightning, internal explosion and smoke. Vandalism can be added (FAIR Plan). It doesn't cover water damage, theft or liability. For those, homeowners add a separate Difference in Conditions policy, called a DIC, from a private insurer. The FAIR Plan itself doesn't sell one (FAIR Plan). The Department of Insurance keeps a list of companies that do (DIC insurers).

The FAIR Plan's maximum is $3 million for all coverages combined on a residential property, not $3 million for the house alone (Department of Insurance). A home that would cost more to rebuild needs additional coverage through a broker. The FAIR Plan also offers its own discounts for hardening a home, worth up to 16.4% of the wildfire portion of the premium (FAIR Plan).

For conventional loans, Fannie Mae accepts a state FAIR Plan policy when it is the only coverage available (Fannie Mae). It caps the deductible, including a separate wildfire deductible, at 5% of the property coverage (Fannie Mae). Lenders can add their own rules, so ask yours in writing early.

What the seller has to tell you

• Natural hazard disclosure. The seller must tell you if the home is in a Very High zone (Civil Code § 1103).
• Home hardening disclosure. If the home is in a High or Very High zone and was built before 2010, the seller must list which known vulnerable features the home has (Civil Code § 1102.6f). These include:
  • vents that are not ember-resistant
  • a wood shake roof
  • combustible materials within five feet of the house
  • single-pane windows
  • uncovered gutters
  That list lines up closely with what insurers and the discount programs look at.
• Defensible space. In High and Very High zones, where the local agency requires or offers an inspection, the seller must provide recent documentation that the property meets defensible space rules. If they can't, you and the seller sign an agreement that you will get it, generally within a year after closing (Civil Code § 1102.19).

Hardening a home, and the new Zone 0 rules

The Department of Insurance's Safer from Wildfires program requires insurers that price wildfire risk to recognize certain mitigation work (Department of Insurance). The list:

• a Class A roof
• ember- and fire-resistant vents
• enclosed eaves
• upgraded windows
• six inches of noncombustible material at the base of exterior walls
• a five-foot ember-resistant zone around the house, including fencing
• cleared space under decks
• sheds moved at least 30 feet away
• defensible space compliance

That five-foot area, known as Zone 0, is also becoming a rule in Very High zones. State law calls for an ember-resistant zone within five feet of the house (Gov. Code § 51182). The Board of Forestry adopted emergency regulations for it on August 19, 2026, and existing homes get a three-year window to comply (Board of Forestry). As of this writing the regulations were awaiting final state approval. If you are buying in a Very High zone, include the bark mulch, wood fences touching the house and plants under windows in your budget.

If the seller's insurer is leaving

Insurers must give at least 75 days' notice before declining to renew a homeowners policy (Ins. Code § 678). So ask whether the seller has received one.

After a declared wildfire emergency, insurers can't cancel or refuse to renew existing policies near the fire for a year based only on the fire (Ins. Code § 675.1). That protects current policyholders. It doesn't require any insurer to write a new policy for a buyer.

When to line up coverage during escrow

1. Before you write an offer, check the address with CAL FIRE's lookup and ask an independent broker for an early read on the address. In Very High areas, ask for a FAIR Plan plus DIC quote at the same time, as a fallback.
2. Right after acceptance, apply for coverage. Ask the seller for their current policy's declarations page and their CLUE report, the claims history on the home, which the owner can request from LexisNexis (LexisNexis).
3. At the inspection, have the inspector note the roof, vents, eaves, windows, gutters and the five feet around the house, since those are what insurers and discounts look at.
4. Before your investigation contingency ends, get a written, bindable quote and send it to your lender. Don't remove the contingency without one.
5. About a week before closing, bind the policy so your lender has proof of insurance.
