In Sonora, the FAIR Plan became the default. It does not have to be yours.
On September 30, 2026, the FAIR Plan, California's fallback fire insurance program, had 5,148 policies in Sonora's 95370, the sixth-most of any California ZIP code. A Department of Insurance bulletin bars wildfire-risk cancellations and non-renewals of 95370 policies in effect on August 6, 2026, during the Gann Fire, for one year. This page covers what the numbers show and where coverage still exists beyond the FAIR Plan.
The short version
- Sonora's 95370 held 5,148 FAIR Plan policies on September 30, 2026, the sixth-most in California, up 56% from 3,310 on September 30, 2022.
- In 2022, the FAIR Plan covered 33.2% of the insured homes in Sonora's 95370, against 3.2% statewide.
- Insurers score house by house, so a hardened home can still get a yes even in a concentrated ZIP code.
- Search standard and specialty insurers in one pass, and if your Sonora home is on the FAIR Plan, search again before your next renewal.
What is happening in Sonora
The FAIR Plan's own quarterly count by ZIP code tells the story. On September 30, 2026, ZIP code 95370, which covers Sonora and the foothill neighborhoods around it, held 5,148 FAIR Plan policies, the sixth-largest count in California. Four years earlier, on September 30, 2022, the same ZIP code held 3,310, so the count grew 56%.
The state marks 95370 as a place where insurance is hard to find, a flag the FAIR Plan reports ZIP code by ZIP code. Sonora is not alone in this. The published list of the ZIP codes with the most FAIR Plan policies reads like a map of the Sierra foothills. Placerville, Grass Valley, Nevada City, and Arnold all sit near the top alongside Sonora.
Numbers like these mean one thing above all. If your policy was non-renewed, or your renewal came in far higher than last year, nothing unusual happened to you. The local market changed around you, and it changed for thousands of your neighbors too.
Why the foothills, and why Highway 108
In Sonora's 95370, the FAIR Plan put 85% of its policies in the High tier of its own wildfire rating on September 30, 2026. Sonora sits in Sierra foothill country. The communities along the Highway 108 corridor climb higher into forested terrain, on steeper ground with fewer roads out. Insurance companies score exactly those things: the fuel around a home, the slope under it, and how a fire crew would reach it.
The foothills also went early. On January 13, 2025, the Department of Insurance said that after the 2018 and 2019 wildfires, FAIR Plan growth in high-wildfire counties "quickly outpaced the statewide growth." By 2022, 33.2% of the insured homes in 95370 were on the FAIR Plan, against 3.2% statewide.
Statewide, 37% of FAIR Plan policies sat in the High tier on September 30, 2026. The statewide count grew 150% from September 30, 2022 to September 30, 2026, against 56% in Sonora's 95370.
One thing the scores do not do is treat the corridor as one place. Insurers' models work house by house: roof material, defensible space, vents, access. Two homes a mile apart on 108 can get different answers from the same company. That is why a neighbor's experience, good or bad, tells you less than it seems to.
What this means for you
If you are on the FAIR Plan, the renewal math is changing. FAIR Plan dwelling rates are 29.1% higher on average for new policies and renewals on or after October 15, 2026. Averages hide a wide spread, and where your home lands depends on its specifics. But a policy you settled into because it was easy to arrange may cost meaningfully more at its next renewal.
Remember what a FAIR Plan policy is: a fire policy, not a homeowners policy. Water damage, theft, and personal liability come from a full homeowners policy in its place, or from the wrap, a second policy beside it. Help with living costs while you rebuild is only a limited option on the FAIR Plan. If you carry only the fire policy, the gap is real. It matters most in exactly the kind of year you bought insurance for.
You may have landed on the FAIR Plan in a hurry after a non-renewal. If so, you may never have learned whether anything else would take your home. That is the default trap: the FAIR Plan is supposed to be the end of a search. For many foothill homeowners, it was the whole search.
Did your FAIR Plan renewal go up?
If your FAIR Plan renewal came in far above last year's, read the notice line by line before you pay it. A new rebuild amount or deductible can move the price too, and any wildfire safety discount you qualify for should be on it.
If it feels like nobody else will insure your home in Sonora, test that before you accept it. Standard insurers and specialty insurers may still write it, sometimes in one policy instead of paying for the FAIR Plan and the wrap. If one does, you can leave the FAIR Plan mid-term with no penalty: start the new policy first, then cancel the old one.
What are the FAIR Plan alternatives in Sonora?
Besides the FAIR Plan, a Sonora home can be insured by standard insurers or by specialty insurers, checked in that order.
First, standard insurers. Some still write in the foothills. A hardened home with documented defensible space is exactly the file that can come back with a yes. Willingness to write differs by company and changes by year, which is why one agent's no is not the market's no.
Second, specialty insurers, the regulated part of the industry built for homes standard insurers step away from. It wrote more than 300,000 California home policies in 2025, up from about 50,000 in 2023, according to the Surplus Line Association of California. These are real policies from rated insurance companies, reached only through a licensed agent. Many homeowners here have never been shown one.
Third, the FAIR Plan itself. For some foothill homes it is the only answer, and there is no shame in that. The right way to arrive is after a full search, not before one.
What to do from Sonora, starting now
None of this requires waiting for a renewal date. The homeowners who do best here start early and put the file together once.
Here is the short list.
- Look up your home on CAL FIRE's Fire Hazard Severity Zone map, free to use. It tells you how the state rates the land, the starting point for every conversation that follows.
- Document the house: roof age and material, with a permit or receipt if you have one. Add the years of plumbing, wiring, and heating updates, and any claims in the last five years.
- Photograph your defensible space after each season's clearing, with dates. Undocumented work gets priced as though it never happened.
- If you are on the FAIR Plan, search standard and specialty insurers again before your next renewal.
- Search in one pass, standard insurers first, then specialty insurers, instead of one phone call at a time.
Questions people ask us
Why did my home insurance go up in Sonora this year?
Insurance companies have long used wildfire risk models to set what each policy costs, the Department of Insurance said on April 4, 2025. FAIR Plan dwelling rates are 29.1% higher on average for new policies and renewals on or after October 15, 2026. Some homes see more than that, and some see less. Either way, one company's renewal is one answer, and it is worth seeing what other standard and specialty insurers say before you accept it.
Is everyone in Sonora on the FAIR Plan?
No. ZIP 95370 had 5,148 FAIR Plan policies on September 30, 2026, by the Plan's quarterly count. That is a lot, and it is still one part of the market: local homes also carry standard or specialty policies.
Does living up the Highway 108 corridor make my home uninsurable?
Harder is not the same as uninsurable. Insurers score house by house: fuel, slope, access, roof, and mitigation. Deeper in the corridor, fewer insurers will look, and the ones that do lean harder on documentation, which is the part you control.
Can Casa get my Sonora home off the FAIR Plan?
No one can promise a particular home an outcome before a search actually runs, and you should be wary of anyone who does. What Casa does is run the search properly: standard insurers first, then specialty insurers. It shows you the quotes it finds, or gives a straight answer, at the end.
