The Short Answer
Before you make an offer on a San Diego home, check two things: whether the address sits in a CAL FIRE fire hazard zone, and whether an insurer will actually write a policy on it. The state redrew San Diego County’s fire maps in 2025, FAIR Plan rates went up October 15, and your lender won’t close without proof of coverage. Do the insurance homework early.
Insurance used to be the last box a buyer checked. In San Diego County right now, I treat it like a second pre-approval: something we line up right alongside the loan. Here’s how I walk my buyers through it.
Did San Diego’s fire hazard maps change?
Yes. In March 2025, the State Fire Marshal released updated Fire Hazard Severity Zone maps for San Diego County, the first update in more than a decade. Acreage in the “very high” category grew about 26%, from roughly 646,800 acres to 817,200, and the maps added moderate and high zones for the first time. Imperial Beach, La Mesa and Lemon Grove showed up on the map for the first time, according to NBC 7 San Diego.
It varies a lot by city. Poway now has nearly 80% of its land in the very high category, while La Mesa and Lemon Grove still have none (inewsource). Inside the city of San Diego, the city’s own mapping notes say Fire-Rescue re-designated areas the state mapped as moderate or high as very high, so the label on your parcel can depend on who’s drawing the line.
One more thing: these maps measure hazard, not risk. CAL FIRE defines hazard as the physical conditions that make a fire likely over a 30-to-50-year window, before counting home hardening (inewsource). And the State Fire Marshal has warned that embers can travel from open land a mile away into neighborhoods that never feel “wild” (KGTV).
Does a fire zone mean I can’t get insurance?
No. A zone isn’t a yes-or-no on coverage. Each insurer sets its own underwriting, and things like the roof, the vents and the brush around the house all matter. State policy is also pushing the market toward more coverage: under Commissioner Lara’s Sustainable Insurance Strategy, insurers that use state-reviewed wildfire models must write policies in wildfire-distressed areas (California Department of Insurance, via InsuranceNewsNet). Availability still varies address by address, which is why I ask buyers to talk to an independent insurance broker before they fall in love with a house.
What is the FAIR Plan, and what does it cover?
The California FAIR Plan is the insurer of last resort. It’s a private association overseen by the Department of Insurance, not a state agency (California Association of REALTORS®). If a broker can’t find you coverage in the regular market, this is the fallback.
The catch: a FAIR Plan dwelling policy is “named peril,” so it only pays for the causes of loss it lists: fire, lightning, internal explosion and smoke, with extras like vandalism available at added cost. For more complete protection, the FAIR Plan itself points owners to a separate Difference in Conditions (DIC) policy, plus flood or earthquake coverage.
- Limit: $3 million for residential property (C.A.R.).
- Cost: C.A.R. put the average premium near $3,200 a year in 2025, and regulators approved a 29.1% average increase on new and renewing policies starting October 15, 2026. That’s a statewide average, not a flat bump for everyone (East County Magazine).
- Lenders: C.A.R. says FAIR Plan fire policies satisfy mortgage lenders’ requirements. I’d still confirm with your own lender up front.
When should I check insurance during the purchase?
Before you write the offer. C.A.R. tells buyers that investigating fire insurance availability and cost is their job, and that the standard purchase agreement includes a specific insurance contingency. If an offer goes in without it, or you remove it, backing out because you can’t get coverage could put you in breach, even with a loan contingency still in place. The default window is commonly 17 days, but your contract spells out the exact terms.
My checklist:
- Ask a broker which carriers are writing in your target ZIP code before you start touring seriously.
- Get quotes on the specific address, including a DIC policy if the FAIR Plan ends up in the mix.
- Hand your lender the insurance binder early. Lenders require proof of coverage before closing, and on a VA loan the first year’s premium is due at or before closing.

Can I lower my premium?
Often a little. California’s Safer from Wildfires framework gives discounts for home-hardening and community-level wildfire work, and a state regulation requires insurers to build wildfire safety standards into their rates. The FAIR Plan offers discounts on the wildfire portion of the premium for fire-resistant roofing, ember-resistant vents and defensible space. Not every insurer offers every discount, so ask for specifics. CAL FIRE also has a free self-assessment tool at fire.ca.gov/dspace.
Selling in a fire zone? Read this first.
Since July 1, 2021, California Civil Code 1102.19 has required sellers in high or very high zones to give buyers documentation of defensible-space compliance. If it isn’t ready by close of escrow, buyer and seller can agree in writing that the buyer will obtain it within one year (Orange County Fire Authority). Thinking of selling?

Quick FAQ
Can I buy a home in a very high fire hazard zone? Yes. A zone doesn’t block a sale. It affects disclosures and defensible-space paperwork, and often insurance cost and availability. Get a quote before you remove contingencies.
Does the FAIR Plan cover everything a homeowners policy does? No. It’s fire-focused, named-peril coverage. Ask your broker about a DIC policy to fill the gaps.
When does my lender need proof of insurance? Before closing. Send the binder as soon as you have it.
Thinking about a specific address?
Send it to me. I’ll look up its fire zone, walk through the disclosures with you and help you build an insurance timeline before you offer. Call or text 619.500.4572, or reach out through my contact page. The first conversation costs you nothing but a phone call.
