From historical averages to forward-looking catastrophe models
For decades, wildfire pricing leaned heavily on what had already happened, essentially a rearview mirror approach to risk. That changed after the January 2025 Los Angeles fires, which may have cost insurers as much as $44.5 billion in payouts, a number few private carriers were prepared to absorb. The scale of that loss pushed regulators and insurers alike toward models that project future risk rather than simply tallying past claims.
California’s own insurance department made this shift official when it approved the first catastrophe model that insurers can factor into the rates they charge policyholders, part of a plan to try to fix the problem and restore insurance availability. These models combine historical data with projected risk and losses, meaning a home’s premium now reflects scenarios that haven’t happened yet, not just fires from years past.
Property-level scoring is replacing the old zip code shortcut
The days of pricing an entire zip code the same way are fading fast. Newer platforms like ZestyAI’s Z-FIRE tool predict the likelihood that a structure will ignite given wildfire proximity, using roof characteristics, defensible space, and other property-specific features. That means two houses on the same street, one with a metal roof and cleared brush, the other with a wood shingle roof and overgrown landscaping, can now receive very different risk scores.
Other providers work the same angle from a different data source. One widely used system evaluates more than 200 unique data points, including property-level attributes like roof type, surrounding vegetation, and even the arrangement of neighboring structures, on the idea that a home with a fire-resistant roof and proper defensible space should not be rated the same as a neighboring home with a shake-shingle roof. This granularity is exactly why two neighbors can open their renewal letters on the same day and see wildly different numbers.
California’s new modeling rules are reshaping what homeowners pay
California spent years resisting forward-looking catastrophe models, worried they would simply be used to justify higher prices without benefiting consumers. That changed in 2025, when regulators completed the review of three forward-looking wildfire catastrophe models, which will help stabilize insurance rates and increase access to coverage statewide. Verisk was the first company to clear that review process, a milestone described as the first time a catastrophe model has successfully completed the evaluation under the state’s new regulatory framework.
The tradeoff for insurers gaining this new pricing tool is a commitment to write more policies in fire-prone areas. Under the state’s approach, carriers that want to use catastrophe modeling must first secure approval through the PRID process and then commit to writing at least 85 percent of their statewide market share in high-risk ZIP codes as identified by the commissioner. Analysts still expect this to raise costs for many households even as it brings some carriers back into a market they had largely abandoned.
Colorado is forcing insurers to show their math
While California leaned into catastrophe modeling, Colorado took the opposite instinct and demanded transparency around it. Governor Polis signed House Bill 1182 in 2025, described as the most significant wildfire insurance regulation Colorado has passed in decades, and it takes effect midway through 2026. The law was born out of regulatory skepticism, since the state’s insurance commissioner had expressed skepticism that the wildfire risk model that most P&C insurance carriers currently use produces accurate risk scores.
Once in force, the law requires that insurers disclose wildfire risk models and explain how those models affect pricing, and consider property-specific mitigation such as defensible space, building hardening, and certifications when calculating rates. For homeowners, this is the first real window into a pricing process that has mostly happened behind closed doors, and it may become a template other wildfire-prone states copy.
The insurer of last resort is quietly becoming the insurer of first resort
When private carriers pull back from a wildfire zone, homeowners typically land in a state-run FAIR Plan, originally designed as a narrow safety net. That net has stretched dramatically in California, where enrollment grew from insuring 210,000 homes in 2020 to over 463,000 in 2024, with total exposure exceeding $450 billion. More recent figures show the trend accelerating even further, with the plan reached more than 668,600 policies statewide by the end of 2025, a 44 percent increased from the fall of 2024.
In the most exposed communities, the FAIR Plan isn’t a backup option anymore, it’s the default. Data from March 2026 shows that in the highest-risk ZIP codes roughly 41 percent of homes are now on the FAIR Plan, with premiums in extreme zones running $5,000 to $25,000 or more a year. That concentration of risk in a single, thinly capitalized program is itself becoming a pricing signal insurers watch closely when deciding where else to pull back.
Non-renewals are the quiet warning sign that arrives before the price hike
Long before a premium doubles, many homeowners get a subtler signal: their policy simply isn’t renewed. In California alone, regulators reported that insurers non-renewed over 2.8 million homeowners policies between 2020 and 2025 in fire-prone ZIP codes. That wave of non-renewals functions as an early, informal repricing of risk, pushing displaced households into the surplus lines market or the FAIR Plan at substantially higher cost.
The pattern isn’t confined to California. In parts of Idaho, residents describe calling 20 or more companies and finding only one willing to quote, often at double the previous rate, a sign that the underwriting retreat is spreading well beyond the states that usually make headlines. Oregon has seen something similar, where major insurers have sharply pulled back from central, southern, and eastern counties, forcing many homeowners to hunt for last-resort coverage or pay quadrupled premiums.
Reinsurance costs are trickling straight down to the homeowner’s bill
Insurers don’t absorb catastrophic wildfire losses alone. They buy their own coverage, called reinsurance, and when that gets more expensive, the cost rarely stays with the insurer. A December 2024 rule change in California means that insurers may pass reinsurance expenses through to policyholders for the first time, a shift that directly links a homeowner’s premium to global reinsurance pricing cycles they’ve never had to think about before.
Nationally, the pressure shows up in broad rate trends rather than a single dramatic jump. Industry forecasts point to home insurance rates rising for a fifth consecutive year, with California rates projected to rise 16 percent as insurers try to recover wildfire losses and implement more advanced risk modeling. Since 2023, the increases have compounded quickly, with the average cost of home insurance up 55 percent as insurers try to recover losses from extreme weather.
Mitigation is starting to show up as a real number, not just a suggestion
For years, homeowners were told that clearing brush or upgrading a roof was simply good practice, without much clarity on whether it actually moved the needle on price. That’s changing as mitigation becomes a formal input into pricing models rather than an afterthought. A recent policy report argues that insurers should no longer treat home hardening as a source of optional premium discounts, but instead as a required input into catastrophe models and underwriting systems.
Some of that shift is already happening in practice. California’s FAIR Plan now offers up to a 13.8 percent discount on the wildfire portion of premium for documented mitigation, with commercial policies eligible for up to 16.4 percent, and several private carriers have followed with similar credits. The catch is that documentation matters as much as the work itself, since insurers generally want verified wildfire mitigation measures supported by photos, receipts, and inspection reports before applying any discount.
Satellite imagery and AI are compressing the time between risk and price
Wildfire pricing used to lag behind reality by months or years, largely because gathering property-level data required manual inspections. Satellite-based tools have collapsed that lag. One widely deployed model, used by a major national carrier across a dozen states, correctly identified 94 percent of the area impacted by the Palisades Fire as high or very high risk before the fire ever started.
The same imagery is now speeding up claims as fast as it speeds up pricing. New parametric products combine radar imagery with automated classification so that SAR imagery is combined with property footprint data and machine learning algorithms to produce a building-level damage assessment, with each insured property classified as either destroyed or undamaged. That kind of instant, binary assessment is a preview of how quickly wildfire risk, and the price attached to it, can now be recalculated after a single satellite pass.
What homeowners can actually do before the renewal notice arrives
The most useful defense against a surprise premium jump is treating mitigation as documentation, not just home improvement. Photographing defensible space, keeping receipts for fire-resistant roofing, and requesting a formal inspection before renewal season gives homeowners a paper trail that increasingly maps directly onto how insurers score a property. In states adopting disclosure laws like Colorado’s, homeowners will also gain a formal right to see the score itself and challenge it.
California has already moved in that direction, giving policyholders the right to receive their wildfire risk score in writing along with an explanation of which property characteristics affected it, along with the right to appeal the score within defined timelines. Homeowners in other wildfire-prone states should expect similar transparency requirements to spread over the next few years, since the underlying pricing technology is now common across the industry rather than confined to a handful of markets.
