What Is a Wildfire Risk Assessment?
It's an insurer's evaluation of how likely your property is to burn, based on vegetation, terrain, and building materials.

Insurers run this assessment before they write or renew your policy, often from aerial imagery and mapping data rather than a visit to your door. It looks at brush or trees near the house, the slope of the land, the roofing and siding, and how far away the nearest fire department is. A high-risk score can mean a higher premium, a requirement to clear brush within a set distance of the house, or a non-renewal letter. If you got that letter, it states the reason. Your declarations page shows your current wildfire-related terms.
A high-risk score from one insurer does not mean the same score everywhere. Insurers weigh vegetation, roofing and distance to a fire station differently, so one company's non-renewal can be another's standard policy at a fair price. If your area has moved into a higher-risk zone, checking what else is out there now shows whether you're still paying for the house you actually have.
Can you do anything to lower your wildfire risk score?
Yes, and some of it is worth doing whether or not it moves the score. Clearing dead brush, trimming branches that overhang the roof, and keeping a cleared buffer around the foundation all reduce the fuel a fire has to work with. Many wildfire-prone states and some counties set specific defensible space rules, like keeping the first five feet around the house free of anything flammable. If your renewal letter mentioned brush clearance, it's likely pointing at this kind of standard.
The building itself matters as much as the landscaping. A composite or metal roof resists embers better than wood shakes. Vents covered with fine metal mesh keep embers from getting into the attic, which is how a lot of homes actually catch fire during a wildfire, not from direct flame contact but from embers blowing in and finding a gap. Dual-pane windows hold up longer under radiant heat than single-pane ones. None of this is cheap to retrofit all at once, but insurers that track wildfire risk closely often ask about these details specifically, sometimes through a questionnaire, sometimes through a point person who reviews the aerial imagery.
Some states now require insurers to recognize this kind of mitigation work in what they charge, though how much credit it earns and how it has to be documented varies by state and by insurer. If you've done the work, ask whether it qualifies for a discount or a different risk tier. Keep records or photos showing what was done and when. A reassessment isn't automatic just because you cleared the brush.
None of this guarantees a lower premium or a renewal, because the terrain and the region's fire history don't change no matter what's done to the house. But two houses with the same surrounding risk can still be scored differently. A metal roof, cleared brush, and ember-resistant vents make for a different underwriting decision than a house without them, even sitting on the same hillside.
What else affects whether you can get coverage at all?
Mitigation work helps, but it isn't the only thing underwriters weigh, and in some areas it isn't enough on its own. A property's wildfire history matters on top of its current condition. A house that's been evacuated or scorched in a past fire, even if it sustained no real damage, often carries that history into future assessments. Some insurers pull data going back a decade or more for the surrounding area, not just the lot itself.
Where the standard market won't write a policy, state-run plans sometimes called FAIR plans exist as a backstop. These typically cost more and cover less than a standard policy, often limited to the dwelling itself with no liability or personal property coverage included automatically. Reaching one of these plans usually means adding a separate policy for what it leaves out. They exist because a state's insurance regulator requires some baseline option, not because they're meant to be anyone's first choice.
Some states have also stepped in with rules about how long an insurer has to keep writing policies in a wildfire-prone area, or restrictions on using wildfire models alone to deny coverage. These rules vary a lot by state and change as fire seasons get worse, so what applied two years ago in a given county may not apply now. If a non-renewal letter cited a wildfire model or a specific risk score, the state insurance department can usually say whether that insurer followed the required process.
None of this is fixed for the life of the house. Risk scores update as fire seasons pass, as mapping data improves, and as the vegetation around a property changes season to season. A score that was high three years ago might look different now, especially if neighboring lots have been cleared or a new fire station opened nearby. Checking in periodically, not just at renewal, is the only way to know if the assessment still matches the property as it actually stands.
