Buying a home in a fire zone

Key takeaways

• Wildfire risk affects more than safety. Insurance availability, premiums, maintenance costs and resale prospects can all be influenced by a home's wildfire exposure, making risk assessment an important part of the buying process.
• Check risk and insurance before making an offer. Buyers should review Fire Factor scores, state wildfire maps and insurance options early, since coverage challenges can delay or even derail a transaction.
• A home's condition can matter as much as its location. Defensible space, fire-resistant materials and completed mitigation work can improve insurability, reduce future costs and make a property more attractive to future buyers.

Buying a home in a wildfire-prone area requires looking beyond the purchase price. Insurance costs, property maintenance and future resale value can all be affected by a home's fire exposure.
According to First Street Foundation, which evaluates communities' wildfire and flooding risks, about 20% of U.S. homes — representing roughly $8.8 trillion in property value — face at least moderate wildfire risk.

As with waterfront properties that carry flood-related costs, homes in fire-prone areas come with risks and expenses buyers may not encounter elsewhere.

This guide explains how to identify wildfire risk, evaluate insurance options and assess a property's overall cost before making an offer.

A wildfire risk zone is an area identified by federal or state agencies as having elevated exposure to wildfires based on factors such as vegetation, terrain, climate and proximity to flammable land. Because classification systems vary, buyers should understand how wildfire risk is measured in the state where they plan to purchase a home.

States use different methods to assess wildfire exposure. California relies on Fire Hazard Severity Zones designated by Cal Fire, which classify areas as Moderate, High or Very High. Colorado's Wildfire Risk Viewer and Texas' Wildfire Risk Explorer provide similar assessments using state-specific data and modeling. Many other western and southern states maintain their own mapping tools and rating systems.

A broader hazard designation doesn't tell the whole story. The Home Ignition Zone, or HIZ, is a concept developed by USDA Forest Service researcher Jack Cohen in the late 1990s that focuses on the area immediately surrounding a structure. The zone typically extends about 100 feet from a home on flat ground and up to 200 feet on steep slopes.

Conditions within that perimeter often play a major role in determining whether a home survives a wildfire. Landscaping, building materials and the distance between the structure and nearby vegetation can make one property more vulnerable than another, even when both sit in the same mapped fire area. For buyers comparing similar homes, the zone can help identify which property may require less mitigation work.

Wildfire activity can vary significantly from year to year. The National Interagency Coordination Center reported 77,850 wildfires nationwide in 2025, up from 64,897 in 2024, while total acres burned fell to 5.1 million from 8.9 million. For buyers in western and southern states, checking a property's wildfire exposure should be as routine as reviewing its flood risk or school district.

Buyers can evaluate a property's wildfire exposure using several free public tools. One of the most widely used is Fire Factor, developed by First Street Foundation, which assigns homes a score from 1 (minimal risk) to 10 (extreme risk) based on the likelihood of wildfire exposure over the next 30 years.

1. Search the address on RiskFactor.com to view its Fire Factor score and projected wildfire exposure.
2. Review your state's official wildfire maps. California uses Cal Fire's Fire Hazard Severity Zone maps, while Colorado and Texas provide risk assessment tools through their state forestry agencies.
3. Use the USDA's Wildfire Risk to Communities database for broader context on local vegetation, land use and community-level wildfire exposure.

Because wildfire conditions and mapping methodologies change over time, buyers should verify a property's current status rather than rely solely on listing information. Local fire departments and county planning offices may also provide parcel-specific information.

Insurance is often the biggest wildcard when buying in a fire-prone area. While standard homeowners policies generally cover fire damage, insurers may charge higher premiums, limit coverage or decline to write new policies in higher-risk locations.

That trend has accelerated in recent years, particularly in states such as California, Colorado and Oregon, where some major carriers have reduced their presence in wildfire-exposed markets.

"Insurance is probably the single biggest issue affecting high-risk real estate today," said Jim Sprouse, a certified wildfire mitigation specialist and founder of California-based Ember Pro. "In some cases, we've seen transactions delayed or even fall apart because buyers couldn't obtain affordable insurance or discovered significant mitigation work was needed after they were already under contract."

When private coverage isn't available, many states offer FAIR Plans, short for Fair Access to Insurance Requirements. These state-backed programs provide basic protection against fire and a limited number of other hazards.

California's FAIR Plan, the nation's largest, expanded from about 126,000 dwelling policies in 2018 to 574,000 by March 2025, according to the Natural Resources Defense Council. The increase highlights how many homeowners in wildfire-exposed areas have lost access to traditional coverage.

FAIR Plans generally provide less protection than a standard homeowners policy. Coverage often excludes personal liability and may offer limited protection for personal belongings. To fill those gaps, homeowners frequently buy a supplemental "difference in conditions" policy, adding to their insurance costs.

For buyers, one of the most important steps is obtaining insurance quotes before making an offer. A home's insurability can have a significant impact on its total cost of ownership.

Wildfire exposure can influence property values through insurance costs, buyer demand and future resale prospects. Unlike a mortgage or ownership history, a fire-zone designation stays with the property and affects future buyers as well.

That doesn't necessarily mean homes in wildfire-prone areas lose value. Many such properties are located in desirable mountain, forest or coastal communities where demand remains strong. But higher insurance premiums, mitigation requirements and a smaller pool of prospective buyers can affect pricing and marketability over time. Buyers should factor those costs into their purchase decision rather than focusing solely on the home's listing price.

Owning a home in a fire-prone area can mean higher ongoing expenses. Fire-resistant building materials, vegetation management and defensible-space requirements may increase maintenance and renovation costs. Higher insurance premiums can further raise the cost of ownership.

Disclosure requirements can also influence demand. In many states, sellers must notify prospective buyers when a property is located in a designated wildfire hazard area, which can limit the pool of interested buyers and lengthen marketing times.

Wildfire exposure is one of several location-based factors that can affect a home's value. Just as buyers consider schools, commute times and flood risk, they should also account for how wildfire exposure may influence future costs and resale prospects.

Wildfire exposure doesn't always work against buyers. In some markets, homes in higher-risk areas sell at a discount because of insurance concerns or perceptions about risk. For buyers who can obtain affordable coverage and are willing to invest in mitigation measures, a lower purchase price may help offset some of the added costs of ownership.

"Buyers still want to live in beautiful communities in the wildland-urban interface," Sprouse said. "What slows transactions today is insurance. Homes that have already been hardened and professionally mitigated have a significant advantage because they remove uncertainty from the buying process."

A home's construction and the area immediately surrounding it can have a major impact on its ability to withstand a wildfire. Buyers in fire-prone areas should evaluate both before making an offer.

Defensible space is the buffer between a home and nearby vegetation where combustible materials are reduced to slow the spread of fire. In many states, including California, property owners in designated wildfire areas are required to maintain it.

Failure to maintain defensible space can result in fines and may complicate efforts to obtain or renew insurance coverage. Buyers should inspect the property for clearance around the home, paying particular attention to the area closest to the structure, where wind-driven embers are most likely to ignite vegetation or other flammable materials.

"Before buying, I always recommend getting a professional wildfire risk assessment," said Jim Sprouse, a certified wildfire mitigation specialist and founder of California-based Ember Pro. "Buyers should look at defensible space, especially Zone 0, ember-resistant vents, roofing materials, windows, siding, surrounding vegetation, slope and access for emergency responders. They should also ask for documentation showing what mitigation work has already been completed instead of assuming the home is wildfire ready."

Certain building materials can reduce the likelihood that a home ignites during a wildfire. Features to look for include:

• Class A fire-rated roofs, such as metal, tile or composite materials
• Fiber-cement or stucco siding
• Tempered or dual-pane windows
• Ember-resistant vents
• Enclosed eaves and soffits
• Noncombustible decking materials

Many of these features are required in newer homes built in designated wildfire areas under state and local building codes. Older homes may not include them, leaving buyers to decide whether upgrades are worth the additional cost.

When evaluating an older property, buyers should consider potential retrofit expenses alongside the purchase price. A home that already incorporates wildfire-resistant features may command a higher asking price but could reduce future insurance, maintenance and mitigation costs.

Unlike homes in FEMA-designated flood zones, properties in wildfire-prone areas aren't subject to a federal requirement for separate wildfire insurance. That doesn't mean insurance is optional.

Most lenders require borrowers to carry hazard insurance, which typically includes fire coverage. If a buyer can't obtain insurance, the lender generally won't approve the loan, regardless of whether the property is in a designated fire zone.

Some lenders impose additional conditions for homes in higher-risk wildfire areas. These can include proof that defensible-space requirements have been met, documentation of fire-resistant upgrades or confirmation that adequate insurance is in place. Requirements vary by lender.

To avoid delays, buyers should discuss insurance availability with both their lender and insurance agent during the preapproval process rather than waiting until they're under contract.

Before submitting an offer, buyers should evaluate the property's wildfire exposure, insurance costs and potential mitigation needs.

1. Confirm the property's wildfire exposure. Review the Fire Factor score and any applicable state or local hazard designations.
2. Obtain insurance quotes. Contact multiple carriers to determine coverage options and annual premiums before making an offer.
3. Evaluate the home's construction. Look for fire-resistant roofs, siding, windows and other protective features, and estimate the cost of any needed upgrades.
4. Review seller disclosures. Check for wildfire-related disclosures, prior damage and any history of insurance nonrenewals. 
5. Inspect defensible space. Assess vegetation management and compliance with local wildfire-mitigation requirements.
6. Estimate total ownership costs. Factor in insurance premiums, vegetation maintenance and any fire-hardening improvements alongside the purchase price.
7. Coordinate with your lender. Make sure insurance and any required wildfire-related documentation are in place before closing.

Taking these steps early can help buyers avoid unexpected costs and reduce the risk of delays once a transaction is under contract.

Your lender's insurance requirements don't end when the transaction closes. If your policy is canceled or not renewed, the lender may purchase force-placed insurance on your behalf. Those policies are often more expensive and provide less coverage than a standard homeowners policy.

Homeowners who lose coverage should begin shopping for replacement insurance immediately, including through their state's FAIR Plan if private-market options are limited.

Disclosure requirements vary by state. California, for example, requires sellers to disclose whether a property is located in a designated fire hazard zone through its Natural Hazard Disclosure Statement. Other states, including Colorado and Oregon, have their own disclosure rules.

Even when disclosures are required, buyers should independently verify a property's wildfire exposure using state mapping tools and other publicly available resources.

Yes. Homeowners may become eligible for private coverage if insurers expand their offerings in the area or if the property is upgraded with wildfire-resistant features.

Because insurance availability can change over time, homeowners should periodically compare coverage options, even if they're currently insured through a FAIR Plan.

Not necessarily on a dollar-for-dollar basis. Appraisals are driven largely by comparable sales, and upgrades may not be fully reflected if nearby homes haven't made similar improvements.

Still, wildfire-resistant homes can appeal to more buyers and may be easier to insure, both of which can support resale prospects.

"I don't think anyone should promise that wildfire mitigation will lower insurance premiums because every insurance company evaluates risk differently," Sprouse said. "What we have seen is that mitigation can help homeowners retain traditional insurance and avoid being pushed onto the California FAIR Plan. The bigger story is what mitigation does for marketability. Buyers are purchasing confidence that the property has been properly hardened and won't require tens of thousands of dollars in wildfire upgrades after closing."

It depends on the insurer. Some companies require inspections or documentation, such as building permits, contractor invoices or photographs, before applying a mitigation discount. Others rely on information provided by the homeowner.

Buyers planning wildfire-resistance upgrades should ask their insurer what documentation is required so they can preserve any potential eligibility for discounts at renewal time.
