Wildfire Risk by Address — A Home Buyer's Guide (2026)

You can check wildfire risk by address in about ten minutes, for free. Start with Wildfire Risk to Communities (a USDA Forest Service tool that shows wildfire likelihood and exposure for any community), then layer on your state's official hazard map — in California, that's the CAL FIRE Fire Hazard Severity Zone viewer, which is searchable by address. Before you write an offer, do two more things: call an insurance agent to confirm the home is actually insurable at a price you can live with, and walk the property looking at the roof, the vents, and the first five feet around the foundation. This guide walks through each step, plus the insurance and disclosure rules that catch buyers off guard.

Why Wildfire Risk Is a Home-Buying Question Now

Wildfire stopped being a rural-West-only concern years ago. The Marshall Fire destroyed more than a thousand suburban Colorado homes in December 2021. The Lahaina fire in Hawaii (2023), the Smokehouse Creek fire in the Texas Panhandle (2024), and the Palisades and Eaton fires in Los Angeles (January 2025) each burned through areas full of homes — and New Jersey's Jones Road fire (2025) reminded East Coast buyers that pine barrens burn too.

The common thread is the wildland-urban interface (WUI) — the zone where homes meet or mix with undeveloped vegetation. NIST estimates that about one-third of U.S. housing units and more than 60,000 communities are at risk from WUI fires. In a WUI fire, most homes don't ignite from a wall of flame; they ignite from wind-blown embers landing on receptive fuel — a dry gutter, a wood fence touching the siding, mulch against the foundation. That's why home hardening focuses on the small openings and the first five feet, and why two houses on the same street can face very different odds.

For buyers, wildfire risk shows up in three places: physical danger, insurance cost and availability, and resale value. All three are checkable before you make an offer.

How to Check Wildfire Risk by Address, Step by Step

Step 1: Wildfire Risk to Communities (national baseline)

Wildfirerisk.org was created by the USDA Forest Service at the direction of Congress and was comprehensively updated in 2024. Search any community and you'll see wildfire likelihood, exposure type, and how the area compares to the rest of the state and country.

One honest caveat: it's a community-level tool built from landscape data, not a parcel-level score. It tells you whether the neighborhood sits in a hazardous landscape — it can't tell you whether a specific house has a wood shake roof or brush against the siding. Use it to frame the question, not to answer it completely.

Step 2: State hazard maps

Several states publish their own official maps, and these often carry legal weight (building codes, disclosure requirements, defensible space rules).

• California maintains Fire Hazard Severity Zone (FHSZ) maps rating land as Moderate, High, or Very High. They were comprehensively updated in 2024–2025 for the first time in more than a decade: maps for State Responsibility Areas took effect April 1, 2024, and updated maps for Local Responsibility Areas (city and county fire jurisdictions) rolled out in phases between February and March 2025. Search any address in the official FHSZ viewer. The zone designation matters: it triggers building standards, defensible space law, and seller disclosures.
• Colorado's Forest Atlas hosts the state's wildfire risk viewer with point-level detail — it reports risk within a half-mile of any address. Note that it's built on 30-meter data and the state cautions it isn't intended for site-specific decisions, so treat it as neighborhood context, not a verdict on one lot.
• Washington's Department of Natural Resources publishes a statewide wildfire hazard and risk map along with county-level risk maps.
• Oregon is a special case: the state built a statewide wildfire hazard map under SB 762, but repealed it in June 2025 when Governor Kotek signed SB 83 — the repeal also removed the map's ties to seller disclosures, defensible space mandates, and WUI building codes. Oregon buyers should lean on wildfirerisk.org, county resources, and local Community Wildfire Protection Plans instead, because no statewide regulatory map currently exists.

For other states, search "[state] wildfire risk map" and stick to .gov or state university domains.

Step 3: Local context — CWPPs, Firewise, and disaster history

Three local signals round out the picture. First, look for the area's Community Wildfire Protection Plan (CWPP) — a locally developed plan that maps hazard areas and priority mitigation projects; these are usually posted on county emergency management or fire district websites, so search "[county name] CWPP." Second, check whether the neighborhood is a recognized Firewise USA site using NFPA's site listings; an active Firewise designation means the community does organized risk reduction, and in California it's one of the community-level actions that qualifies for insurance discounts. Third, pull the county's federal disaster history from FEMA's disaster declarations database — repeated fire declarations tell you how often this landscape actually burns, not just how it's modeled.

Step 4: The insurance reality check

Before you write an offer in a fire-prone area, call an independent insurance agent with the exact address and ask two questions: Can I get a standard homeowners policy here, and what will it cost? In parts of California and Colorado, this single phone call kills more deals than the hazard maps do. Get a real quote — not a Zestimate-style guess — because your lender will require proof of insurance to close.

The Wildfire Insurance Problem: FAIR Plans and Discounts

In the hardest-hit markets, private insurers have pulled back, pushing homeowners to FAIR Plans — state-organized insurers of last resort that offer basic (and often more expensive, less comprehensive) coverage.

• The California FAIR Plan has grown dramatically as private carriers non-renewed policies in high-hazard zones; by early 2026 it covered roughly 655,000 residential policies. A FAIR Plan policy typically covers fire but not everything a standard HO-3 policy would, so many owners pair it with a separate "difference in conditions" policy.
• Colorado stood up its first FAIR Plan, which began accepting applications in April 2025. It's sold through licensed agents, not directly.

If a house can only be insured through a FAIR Plan, that's a material fact about ownership cost and resale. Budget for it, and ask the seller's agent whether the current owner was non-renewed.

The flip side: mitigation can earn money back. California's Safer from Wildfires framework requires insurers to offer discounts for specific actions — a Class-A roof, ember-resistant vents, upgraded windows, a five-foot ember-resistant zone, defensible space compliance, and community programs like Firewise USA.

Defensible Space Zones 0, 1, and 2

Defensible space is the buffer between a house and the vegetation around it. California's framework — widely used as a model elsewhere — divides it into three zones:

Zone	Distance from structure	Focus	Examples
Zone 0 (ember-resistant zone)	0–5 ft	Nothing combustible touching the house	Gravel or hardscape instead of mulch; no shrubs against walls; no firewood or combustible fencing attached to the home
Zone 1 (lean, clean, green)	5–30 ft	Remove dead material, create separation	Cleared dead plants and leaves; trimmed tree branches 10 ft from other trees; space between shrubs
Zone 2 (reduced fuel)	30–100 ft	Reduce fuel continuity	Mowed grass to 4 in; horizontal and vertical spacing between trees and shrubs; thinned brush

A note on Zone 0's legal status: California created the ember-resistant zone concept in statute (AB 3074), and Executive Order N-18-25 directed the Board of Forestry to adopt Zone 0 regulations by December 31, 2025. As of mid-2026 the rules are still in draft — the Board missed that deadline, and revised draft text was still circulating in spring 2026. The proposed phase-in would apply to new construction in Very High Fire Hazard Severity Zones immediately upon adoption, with existing homes following on a multi-year timeline. If you're buying in a High or Very High zone, plan and budget as if Zone 0 compliance will be required during your ownership, because it very likely will be.

When you tour a property, you can eyeball all three zones in five minutes. Vegetation is fixable; a house sitting at the top of a brushy slope with a wood deck cantilevered over the vegetation is a harder problem.

Home Hardening: What to Look For on a Showing

Research from NIST and the Insurance Institute for Business & Home Safety (IBHS) consistently points to the same vulnerabilities. Check these during your showing and again during inspection:

1. Roof material. A Class A fire-rated roof (asphalt shingle, metal, tile) is the baseline. A wood shake roof is one of the biggest red flags — some insurers won't write a policy on one in a hazard zone at all.
2. Vents. Embers enter attics and crawl spaces through vents. Look for ember-resistant vents or 1/16-to-1/8-inch corrosion-resistant metal mesh over every opening.
3. Windows. Multi-pane (dual-pane or better) windows resist breaking from radiant heat; single-pane windows in a hazard zone are a retrofit line item.
4. The first five feet. Mulch beds, wooden gates attached to the house, and shrubs under windows are the classic ember-ignition pathway.
5. Decks, fences, and gutters. Combustible fencing that connects to the structure acts as a fuse. Debris-filled gutters are ember beds.

None of these individually kills a deal — they're negotiation and budgeting items. IBHS's Wildfire Prepared Home program is a useful checklist for what a fully hardened home looks like, and in California completing these upgrades feeds directly into Safer from Wildfires insurance discounts.

Wildfire Disclosure Laws: What Sellers Must Tell You

Disclosure varies enormously by state:

• California has the strongest regime. Under AB 38 (Civil Code §1102.19), sellers of homes in High or Very High Fire Hazard Severity Zones built before 2010 must deliver a statutory home-hardening disclosure, and sellers must document compliance with defensible space law. Since mid-2025, the disclosure also covers which retrofits from the state's low-cost hardening list have been completed. Read these documents carefully — they're a free, seller-funded risk report.
• Oregon briefly tied a WUI question to its seller disclosure form under the statewide map program, but SB 83 (2025) removed it along with the map itself. Oregon buyers should assume the disclosure form won't flag wildfire hazard and do their own checking.
• Most other states have no wildfire-specific disclosure. General disclosure forms may capture past fire damage, but the hazard itself is on you to research.

Wherever you're buying, ask the listing agent directly: Has this property ever been non-renewed for insurance, and is there any past fire damage or claim history?

Pre-Offer Wildfire Checklist

1. Look up the community on wildfirerisk.org — note wildfire likelihood vs. the state average.
2. Check the state hazard map (in California, the FHSZ viewer by address) and record the zone designation.
3. Pull the county's fire disaster history from FEMA.
4. Get a real insurance quote for the exact address before writing the offer.
5. On the showing, photograph the roof, vents, and the first five feet around the structure.
6. Ask for defensible space compliance documentation and any state-required hardening disclosures.
7. Search "[county] CWPP" and check the community's Firewise USA status.
8. If the quote comes back FAIR-Plan-only, price in the coverage gap before you negotiate.

Wildfire is one line on a longer due-diligence list — flood zones, radon, and environmental sites deserve the same treatment. See our home buyer due diligence checklist, plus guides on checking flood zones and EPA radon zones by county.

FAQ

Is there a free tool that shows wildfire risk for a specific address?

Not with true parcel precision. Wildfirerisk.org is community-level; California's FHSZ viewer is searchable by address and shows the official zone the parcel falls in; Colorado's Forest Atlas viewer reports risk within a half-mile of a point but isn't designed for site-specific decisions. The most address-specific inputs are the official zone designation plus your own eyes on the structure and its first five feet.

What does it mean if a house is in a Very High Fire Hazard Severity Zone?

In California, a Very High designation triggers Chapter 7A building standards for new construction, defensible space requirements, seller disclosure obligations under AB 38, and — once adopted — Zone 0 ember-resistant zone rules. Practically, it also means tougher insurance underwriting. It does not mean the house will burn; it means the state's fire scientists rate the surrounding hazard in the top tier and you should verify insurance and mitigation before buying.

Can I get homeowners insurance in a high wildfire risk area?

Usually yes, but possibly not from a standard carrier and not cheaply. If private insurers decline, state FAIR Plans (California's is the largest; Colorado's began accepting applications in April 2025) provide basic last-resort coverage, often paired with a supplemental policy. Always get a bindable quote before removing contingencies.

Do sellers have to disclose wildfire risk?

Only in some states. California requires hazard zone and home-hardening disclosures under AB 38 for qualifying homes. Oregon removed its WUI disclosure item when SB 83 repealed the state hazard map in 2025. In most states, there's no wildfire-specific disclosure — the research burden is on the buyer.
