Private insurers wrote 28% fewer California homeowners policies in 2023 than in 2020. In 46 of 58 counties, non-renewals outnumbered new policies written, meaning the private market actively contracted across most of the state. The California Department of Insurance recorded 788,485 homeowners policy non-renewals statewide in 2023. The CDI estimates 20% to 25% of those were insurer-initiated; the remainder reflect policyholder decisions like switching carriers or selling a home.

The pullback shows up most clearly in FAIR Plan enrollment. California's FAIR Plan, the state's insurer of last resort, grew from 242,440 residential policies in September 2021 to 642,010 in September 2025, a 165% increase. Before placing a FAIR Plan policy, a broker must conduct a diligent search of the traditional market, so enrollment growth tracks directly where private insurers have stopped writing policies.

MoneyGeek analyzed six independent datasets, county-level wildfire risk data from FEMA's National Risk Index (December 2025), building exposure data from the USDA's Wildfire Risk to Communities database (May 2025), enrollment records and ZIP-code-level exposure data from the California FAIR Plan (September 2025), non-renewal data from the California Department of Insurance (2020 to 2023) and home values from the Zillow Home Value Index (February 2026), to map where insurer pullback is most severe and which homeowners are left relying on the state's backup option. Because these datasets cover different reporting periods, the analysis is cross-sectional rather than a single point-in-time snapshot.

KEY FINDINGS
  • In 46 of 58 California counties, non-renewals outnumbered new policies written in 2023, meaning the private homeowners insurance market contracted across most of the state.
  • Residential FAIR Plan total insured value reached $633 billion as of Sept. 30, 2025, up 314% since 2021. The single most-exposed ZIP code, 96161 in Truckee, carries $9.1 billion in FAIR Plan residential exposure.
  • Four counties, San Diego, Riverside, Los Angeles and San Bernardino, carry a combined $1.08 billion in expected annual wildfire loss and account for more than half of all FAIR Plan policies statewide.
  • Non-renewal rates in the 10 counties with the highest wildfire exposure hit 16.3% in 2023, nearly double the statewide rate of 8.7% and up from roughly 5% in 2015.
  • Ninety percent of FAIR Plan policies are in counties FEMA rates as "Relatively High" or "Very High" for wildfire risk, per MoneyGeek's analysis of FAIR Plan county data cross-referenced with FEMA's National Risk Index.
  • New homeowners policies written in California dropped 28%, from 1,007,422 in 2020 to 724,037 in 2023. The CDI recorded 788,485 non-renewals statewide in 2023; the agency estimates 20% to 25% were insurer-initiated.
  • FAIR Plan residential policies grew 165%, from 242,440 in September 2021 to 642,010 in September 2025. The FAIR Plan's share of the residential market rose from 1.6% in 2018 to 3.7% in 2023. In the top 10 wildfire-risk counties, roughly one in three residential policies is now written by the FAIR Plan.

What the FAIR Plan Growth Tells Us About Insurer Retreat

California’s FAIR Plan enrollment has nearly tripled since 2021. The FAIR Plan isn’t a discount option or a government subsidy. Before placing a policy, a broker must conduct a diligent search of the traditional market, so FAIR Plan enrollment serves as a proxy for residential properties that could not find acceptable coverage from private insurers. That residential policy count went from 242,440 in September 2021 to 642,010 in September 2025.

Los Angeles County leads the state with 154,765 FAIR Plan policies as of September 2025, an 83% increase over four years. San Bernardino County follows with 65,132 policies (109% growth), then San Diego at 59,063 (379% growth) and Riverside at 57,026 (509% growth).

These four counties alone hold 335,986 FAIR Plan policies, 52% of the statewide total. All four carry FEMA’s highest wildfire risk rating of “Very High.”

The growth isn’t limited to Southern California’s largest metro areas. El Dorado County in the Sierra Nevada foothills has 28,167 FAIR Plan policies, up 100% since 2021. Orange County jumped 481% to 23,748 policies. Nevada County, with a population just over 102,000, now has 23,438 FAIR Plan policies.

ZIP Codes Carrying the Most FAIR Plan Exposure

County averages can mask sharp local concentrations of risk. FAIR Plan exposure data broken down by ZIP code, measured in total insured value (TIV), shows where the state’s backup insurer is shouldering the most financial risk.

Statewide, residential FAIR Plan TIV reached $633 billion as of Sept. 30, 2025, up 314% from $153 billion four years earlier. The 15 ZIP codes with the highest FAIR Plan residential TIV carry $83 billion, 13% of the statewide total.

Truckee-area ZIP 96161, which spans Placer and Nevada counties, leads all California ZIP codes with $9.1 billion in FAIR Plan residential exposure, a 224% increase since 2021. Lake Arrowhead (92352) in San Bernardino County follows at $7.0 billion. Placerville (95667) in El Dorado County ranks third at $6.8 billion, up 132% over four years.

Los Angeles County places four ZIP codes in the top 15: Beverly Hills (90210) at $6.0 billion, Calabasas (91302) at $5.4 billion, Malibu (90265) at $5.1 billion and Brentwood (90049) at $4.8 billion. All four are in or adjacent to the Santa Monica Mountains, one of the state’s most wildfire-prone corridors.

Several ZIP codes show explosive four-year growth that reflects new risk zones where private insurers have recently pulled back. Orinda (94563) in Contra Costa County grew more than 2,600%, from $207 million to $5.7 billion in TIV. Fallbrook (92028) in San Diego County surged nearly 800%. These aren’t only remote mountain communities; they also include suburban neighborhoods where FAIR Plan reliance has risen rapidly.

Across the state, 172 ZIP codes now carry $1 billion or more in FAIR Plan residential exposure, and those ZIP codes account for 59% of the statewide total. Four years ago, the same threshold would have captured far fewer communities.

The Counties Where Fire Risk Is Highest

Two independent federal datasets confirm which California counties are most at risk from wildfire: FEMA’s National Risk Index and the USDA’s Wildfire Risk to Communities model.

FEMA’s index covers multiple hazards, but for this analysis MoneyGeek uses only the wildfire-specific fields: expected annual loss and county wildfire risk rating. Four California counties, San Diego, Riverside, Los Angeles and San Bernardino, carry a “Very High” risk rating. San Diego County alone accounts for $430 million in expected annual wildfire loss, the highest of any county in the state. Riverside follows at $347 million, Los Angeles at $155 million and San Bernardino at $146 million.

Together, those four counties represent 60% of California’s total expected annual wildfire loss of $1.79 billion.

The USDA’s model measures something different: the percentage of buildings in each county that are in the direct path of potential wildfire. By this measure, rural Sierra Nevada and Northern California counties are the most exposed.

Across the state, 19 counties have more than half their building stock directly exposed to wildfire, according to USDA data. And 44 of California’s 58 counties rank in the top 10% nationally for wildfire risk.

Where Risk and Abandonment Overlap

The data shows a consistent pattern: as wildfire risk increases, private insurance availability drops, non-renewal rates climb and FAIR Plan enrollment grows.

MoneyGeek cross-referenced September 2025 FAIR Plan county policy counts with FEMA’s National Risk Index to find that of the 642,010 active policies, roughly 580,000, or 90%, were in counties FEMA rates as “Relatively High” or “Very High” for wildfire risk. Only 10% were in counties with moderate, low or very low ratings.

That concentration matters because the FAIR Plan was never designed to be a primary insurer for hundreds of thousands of properties. It offers more limited coverage than most private policies, and its premiums have risen as its risk pool has expanded. A homeowner on the FAIR Plan doesn’t include theft, liability or water damage unless they buy a separate “difference in conditions” policy.

The counties with the steepest FAIR Plan growth rates show how quickly private insurers are pulling back from new areas. Contra Costa County went from 1,094 FAIR Plan policies in 2021 to 12,837 in 2025, a 1,073% increase. Solano County grew 799%, from 146 to 1,312 policies. Riverside County, already one of the state’s most wildfire-prone areas, saw 509% growth.

Several of these fast-growing counties are in the San Francisco Bay Area and Central Valley, regions that historically weren’t considered wildfire hot spots. That shift suggests private insurers are reassessing risk across a broader geography than the traditional mountain and canyon areas.

Where Insurers Are Non-Renewing Policies

FAIR Plan growth tells us where homeowners are ending up. California Department of Insurance data tells us where they’re being pushed out.

In 2023, the CDI recorded 788,485 homeowners policy non-renewals statewide. That total includes both insurer-initiated non-renewals and policyholder-driven changes like switching carriers or selling a home; CDI estimates 20% to 25% were insurer-initiated. The raw count is down from a peak of 1,037,767 in 2021, but that decline is misleading: new policies written also dropped sharply, from 1,007,422 in 2020 to 724,037 in 2023, a 28% reduction. Fewer policies are being written in the first place, which reduces the pool of policies that can later show up as non-renewals.

MoneyGeek’s county-level non-renewal rate, calculated from CDI’s raw data, tells a clearer story. Tuolumne County had the highest rate in 2023 at 17.8%, meaning nearly one in five homeowners policies wasn’t renewed. Nevada County followed at 17.2%, then Lake County at 14.4%, Calaveras at 14.3% and Plumas at 14.3%. All five rank in the top 1% nationally for wildfire risk according to USDA data.

By volume, the biggest counties lead the totals. Los Angeles County saw 155,768 non-renewals in 2023, more than any other county. Riverside followed with 74,877, San Diego with 62,683 and San Bernardino with 57,532. Those four counties alone accounted for 350,860 non-renewals, 45% of the statewide total.

Counties Where the Private Insurance Market Is Shrinking

The most telling metric is where non-renewals outnumbered new policies written, because that means the private market is actively contracting. In 2023, 46 of 58 California counties crossed that line. Only 12 counties wrote more new policies than they lost to non-renewals.

According to the CDI’s January 2025 fact sheet, the non-renewal rate in the 10 counties with the highest wildfire exposure hit 16.3% in 2023, nearly double the statewide average of 8.7% and up from roughly 5% in 2015.

The CDI also reported three tiers of FAIR Plan market penetration. Statewide, the FAIR Plan’s share of the total residential insurance market grew from 1.6% in 2018 to 3.7% in 2023. In counties at or above the 50th percentile for wildfire risk, FAIR Plan market share rose from 1.6% to 10% over that same period. And in the top 10 wildfire-risk counties, FAIR Plan policies reached 32.6% of the residential market by 2023, meaning roughly one in three policies in those areas is now written by the insurer of last resort.

The Rural Exposure Problem

While the largest raw numbers are in Southern California’s urban counties, the most concentrated risk is in California’s smaller, rural communities.

In Mariposa County, where 95% of buildings are directly exposed to wildfire, the FAIR Plan holds 3,404 policies. That county has a population of 17,060 and 16,578 total buildings. As a rough scale comparison, that’s about one FAIR Plan policy for every five structures, though FAIR policies can include rentals, condos and seasonal properties, not just owner-occupied homes.

Tuolumne County has 83% of buildings in direct wildfire exposure zones and 14,071 residential FAIR Plan policies out of 44,249 total buildings, roughly one for every three structures by the same approximate comparison. El Dorado County’s 28,167 FAIR Plan policies represent about 28% of its 100,465 buildings by the same approximate measure.

For these communities, the insurance gap creates a compounding problem. Homeowners who can’t get affordable private coverage may struggle to sell their properties, potentially pressuring local property values, shrinking the tax base and reducing funding for the fire mitigation services needed to lower risk.

How Much Wealth Is at Risk

Zillow Home Value Index data adds a dollar figure to the crisis. The typical home in Los Angeles County is worth $879,000. In San Diego County, it’s $928,000. In Orange County, $1,170,000. For many households, these homes represent their largest financial asset, and they’re in counties where insurers are pulling back.

Across the 10 counties with the most FAIR Plan policies, the median of county-level Zillow typical home values is $661,000, according to Zillow’s February 2026 estimates. In the four counties FEMA rates as “Very High” wildfire risk, Los Angeles, San Diego, Riverside and San Bernardino, the typical home ranges from $547,000 (San Bernardino) to $928,000 (San Diego).

Some of California’s highest-risk, most insurance-stressed counties are also posting year-over-year home value declines, raising the question of whether insurance availability could become a housing-market headwind. YoY price changes reflect many factors, including mortgage rates, local economic conditions and inventory mix, so the overlap alone doesn’t prove causation. But for homeowners already paying more for less coverage, falling property values add another layer of financial pressure.

Why Insurers Are Leaving

Private insurers have pulled back from California’s wildfire zones for reasons that show up in the loss data. FEMA estimates California’s expected annual wildfire loss at $1.79 billion, and that figure reflects modeled long-term averages, not worst-case scenarios.

The 2018 Camp Fire in Butte County killed 85 people and destroyed more than 18,000 structures. The 2020 and 2021 fire seasons burned through several Northern California communities. The January 2025 fires in Los Angeles County caused approximately $40 billion in insured losses, per Swiss Re and Munich Re reports published in early 2026, the costliest wildfire event on sigma record.

For insurers, the math has shifted. The cost of covering wildfire-prone properties now exceeds what regulators have historically allowed companies to charge in premiums. California’s regulatory framework, which until recently required insurers to base rates on historical losses rather than forward-looking catastrophe models, prevented carriers from pricing for growing risk.

In September 2025, California Insurance Commissioner Ricardo Lara finalized new rules allowing insurers to use catastrophe models in rate-setting, a change aimed at keeping private carriers in the market. But the FAIR Plan’s enrollment numbers suggest that, for now, the pullback continues.

The CDI county dataset does not break out non-renewals by individual carrier, so this analysis cannot identify which specific insurers have pulled back most. NAIC company-level market-share data, which MoneyGeek plans to analyze in a follow-up report, would help answer that question.

HOW CALIFORNIA COMPARES

California’s wildfire insurance crisis is the most severe in the country, but it’s not the only state affected.

Colorado launched its own FAIR Plan on April 10, 2025, after homeowners premiums in the state rose 58% between 2018 and 2023, per the Rocky Mountain Insurance Information Association. Oregon has seen premiums increase more than 27% since 2020, according to the Consumer Federation of America. Washington, Montana and Idaho are all reporting growing pressure on homeowners insurance availability in wildfire-prone areas.

Nationally, FAIR Plans and similar residual market programs covered nearly 3 million properties with total exposure exceeding $1 trillion in fiscal year 2024, according to the Insurance Information Institute.

The pattern across these states mirrors what the California data shows at the county level: insurers are repricing or exiting the markets where wildfire risk is growing, and state-backed programs are absorbing the overflow.

What This Means for Homeowners

If you own a home in one of the counties identified in this analysis, your insurance options are increasingly limited.

Check whether your county is in a high-risk zone. The USDA’s Wildfire Risk to Communities tool lets you look up risk scores for any address in the country. FEMA’s National Risk Index provides county-level risk ratings and expected loss estimates. MoneyGeek’s California homeowners insurance calculator can help you estimate premiums in your area.

Understand what FAIR Plan coverage does and doesn’t include. A standard FAIR Plan policy covers fire damage only. It doesn’t include liability, theft or water damage. Homeowners who need broader protection must buy a separate difference-in-conditions (DIC) policy from a private insurer, which adds cost.

Ask your insurer about renewal. California’s moratorium protections, which the state’s insurance commissioner has applied after major wildfires, have prevented some non-renewals. But those protections are temporary and apply only to specific disaster areas. If you’re in a high-risk county, ask your agent whether your policy is at risk of non-renewal at the next cycle.

Look into home hardening. California offers incentives for fire-resistant retrofits, including defensible space clearing, ember-resistant vents and fire-rated roofing. Some insurers offer discounts for homes that meet Firewise USA or similar standards. The California Department of Insurance lists mitigation programs online. A home inventory documenting your property and improvements can speed up claims if you ever need to file.

Methodology

MoneyGeek merged six publicly available datasets to identify where high wildfire risk, insurer retreat and FAIR Plan enrollment overlap across California's 58 counties. ZIP-code-level FAIR Plan exposure data was analyzed separately to identify communities with the highest concentrations of state-backed coverage. Because the six datasets cover different reporting periods, the analysis is cross-sectional rather than a single point-in-time snapshot.
