The short answer: Home insurance is now one of the biggest variables in what a California home really costs to own. This fall brings a few changes worth knowing: the Department of Insurance has started publishing more of its rate-review work, FAIR Plan growth has slowed as some private carriers return, and FAIR Plan premiums rose an average of about 29% on October 15. If you're buying, get insurance quotes before you write an offer; if you already own, shop your renewal early and make sure you're getting every wildfire-mitigation discount you've earned.

As of October 26, 2026.

Why does home insurance matter so much when you buy or refinance?

No lender will fund a home loan without proof of insurance, and the premium is part of the monthly housing payment we qualify you on. A higher premium can lower how much home you qualify for, and if your insurance is paid through escrow, any increase eventually shows up in your monthly payment.

Lenders also have rules about what the policy must cover. For a Fannie Mae loan on a one-to-four-unit home, the property must be insured on a replacement-cost basis (roofs are the exception), the deductible can't be more than 5% of the coverage amount, and if a policy excludes or limits a required peril, you need an additional policy to cover it (Fannie Mae Selling Guide B7-3-02). That last rule is why many FAIR Plan homeowners pair their fire policy with a separate "difference in conditions" policy for things like water damage and liability.

What's changing in California home insurance this fall?

More visibility into rate reviews. On October 19, 2026, the California Department of Insurance announced that its Comprehensiveness Review Regulation had been approved. It creates a voluntary review step before an insurer formally files for a rate change under Proposition 103. The Department says it will make initial rate range indications public and publish the savings its rate staff predict, including the dollar amounts and the issues flagged in each submittal. Insurers can skip the step and file a formal rate application instead. The Department reports that its review of rate filings has saved consumers $6.6 billion since 2019 (CDI, October 19, 2026).

What this means for you: it won't lower anyone's bill overnight, but homeowners and buyers will be able to see more about how proposed rate increases are reviewed and trimmed.

FAIR Plan growth is slowing. The Department reported on August 3, 2026 that FAIR Plan policies grew 1.9% (12,305 policies) in the second quarter, the third straight quarter of slowing growth and the smallest quarterly increase since 2022. About 24,000 policies left the FAIR Plan in April and May. The Department lists 11 insurance groups that have committed to stay and grow in California, including Farmers, Mercury, Auto Club of Southern California, CSAA, USAA, Liberty Mutual and Travelers (CDI, August 3, 2026).

FAIR Plan premiums went up. FAIR Plan dwelling rates rose an average of about 29% (29.1%) for new and renewing policies starting October 15, after the plan first asked for 35.8%. Homes in high-risk, fire-prone areas face the largest increases, and some policyholders will see decreases (Orange County Register via InsuranceNewsNet, May 20, 2026). I walked through how that reaches your escrow payment in The FAIR Plan's 29% Rate Increase Is Here.

How should buyers handle insurance before making an offer?

In fire-prone parts of Los Angeles County, the Inland Empire foothills and the Sierra, insurance can swing the true cost of a home as much as the price does. A few practical habits:

  • Quote the address, not the neighborhood. Two homes on the same street can get very different answers depending on roof, brush clearance and fire-risk scoring.
  • Ask early whether private coverage is available. If only the FAIR Plan will write the home, budget for both the FAIR Plan policy and a difference in conditions policy.
  • Give yourself time. Getting insurance bound is a closing condition. Don't leave it for the last week of escrow.

How can homeowners lower what they pay at renewal?

Claim your wildfire-mitigation discounts. Under California's Safer from Wildfires framework, insurers must offer discounts to residential policyholders for steps like a Class A fire-rated roof, a 5-foot ember-resistant zone around the house, ember- and fire-resistant vents, double-pane windows or shutters, enclosed eaves, and moving sheds at least 30 feet away. Community steps count too, such as forming a Firewise USA community. Discount amounts vary by insurer, and the FAIR Plan offers discounts as well through registered brokers (CDI, Insurers Currently Offering Discounts).

Shop the market every year. The Department's own advice is to shop regularly rather than assume the FAIR Plan is your only option: contact several agents and brokers, compare coverage and price, and ask specifically about companies writing new policies in your area (CDI, August 3, 2026).

Keep your records handy. Photos and receipts for roof work, vents and defensible space make it easier to get discounts and to show a new carrier the home is lower risk.

Reading from outside California? Insurance is regulated state by state, so the FAIR Plan and Safer from Wildfires rules are California-specific. The lender coverage rules above apply to Fannie Mae loans anywhere.

Derek\'s take

In 20 years and more than 1,200 loans, I've never seen insurance play as big a role in California home decisions as it does right now. The good news is you have more control than it feels like: quotes before you offer, discounts for work you've already done, and a fresh look at the market every year. I can help you see how a premium changes what you qualify for, whether a refinance or HELOC still makes sense with your new insurance bill, and what to line up before you write an offer. If that would help, book a call with me. Thirty minutes, no credit pull, no obligation.

Frequently asked questions

Do I need homeowners insurance to get a mortgage in California?

Yes. Lenders require proof of adequate coverage before closing, and the premium is counted in your monthly housing payment when you qualify.

Will my lender accept a FAIR Plan policy?

Generally yes, as long as total coverage meets the loan's rules. Because the FAIR Plan covers a limited set of perils, many owners add a difference in conditions policy so all required perils are covered.

What is the new rate-review rule from the Department of Insurance?

The Comprehensiveness Review Regulation, announced October 19, 2026, adds an optional review step before an insurer formally files for a rate change, and the Department says it will publish initial rate range indications and the savings its staff predict.

Is the FAIR Plan shrinking?

Not yet, but growth has slowed. Policies grew 1.9% in the second quarter of 2026, the smallest quarterly increase since 2022, and about 24,000 policies left the plan in April and May.

How far ahead should I shop my homeowners insurance renewal?

Start 60 to 90 days before it renews so you have time to compare quotes and apply any mitigation discounts.
