Wildfire exposure is no longer viewed as a seasonal or isolated issue. Across the United States, wildfire losses have become larger, more destructive, and increasingly difficult for insurance markets to predict. In response, regulators, municipalities, and insurance carriers are placing greater focus on mitigation, resilient construction, and long-term catastrophe management.
Colorado’s new wildfire resiliency legislation is one example of how quickly this issue is evolving. In 2023, the state enacted legislation creating a statewide Wildfire Resiliency Code Board tasked with developing minimum building standards for properties located in the Wildland-Urban Interface (WUI), areas where residential and commercial development intersects with undeveloped land and wildfire exposure.1 The code focuses on wildfire-resistant construction, defensible space, vegetation management, and mitigation strategies designed to reduce property losses during wildfire events.
The shift comes as wildfire losses continue to escalate nationwide. According to Insurance Journal, insured losses from wildfires are increasing by an estimated 12% per year.2 Colorado has experienced particularly severe wildfire activity in recent years. Seventeen of the state’s twenty largest wildfires have occurred since 2012, highlighting how rapidly wildfire severity has intensified.3
The 2021 Marshall Fire further changed the conversation around urban wildfire risk. The fire destroyed over 1,000 homes and caused over $2 billion in damage, becoming one of the most destructive wildfires in Colorado history.4 Unlike many historic wildfire events that primarily affected remote or rural areas, the Marshall Fire devastated densely populated suburban communities, demonstrating that wildfire exposure now extends far beyond traditional mountain regions.
For insurance markets, this is more than a regulatory issue. It represents a fundamental change in how wildfire risk is evaluated, modeled, and underwritten.
WILDFIRE IS NO LONGER JUST A RURAL EXPOSURE
Historically, wildfire underwriting focused on remote mountain homes, heavily forested regions, and rural Western geographies. Today, carriers evaluate wildfire exposure very differently. Population growth, suburban expansion, drought conditions, and changing weather patterns have significantly expanded the WUI footprint across many states. According to the U.S. Fire Administration, approximately 60,000 communities nationwide are now located in wildfire-prone areas.5 As development continues pushing into previously undeveloped land, wildfire exposure is becoming increasingly common in suburban and even urban-adjacent communities.
Carriers are also becoming more sophisticated in their evaluation of aggregation exposure. Instead of focusing only on broad geographic regions, many insurers now analyze concentration risk at the street or neighborhood level. Underwriters are increasingly evaluating roof materials, vegetation clearance, ember-resistant construction, defensible space, and proximity to unmanaged brush before determining eligibility or pricing.
Properties once considered “moderate risk” are now facing greater underwriting scrutiny as carriers place increased emphasis on factors such as wind exposure, vegetation, development density, and community mitigation efforts. As wildfire underwriting continues to evolve, the impact is extending well beyond personal lines, affecting habitational portfolios, HOAs, municipalities, healthcare, hospitality, real estate, and other commercial risks.
HOW WILDFIRE BUILDING CODES COULD AFFECT INSURANCE MARKETS
As wildfire-resilient building standards become more common, insurance markets are closely monitoring how these changes may influence long-term loss performance.
Colorado’s statewide wildfire code is intended to create more consistent mitigation standards across communities. Requirements may include noncombustible roof materials, ember-resistant vents, defensible space requirements, vegetation management, and wildfire-resistant siding or construction materials.1
Over time, resilient construction standards could help improve overall property survivability during wildfire events. However, the transition period may create new underwriting complexity. Some carriers may continue to rely heavily on wildfire-mapping tools regardless of mitigation features, while others may begin placing greater value on resilient construction and community-level mitigation programs.
In some cases, mitigation efforts are already influencing underwriting eligibility. For example, properties located in National Fire Protection Association (NFPA) Firewise USA® communities may receive more favorable underwriting consideration than similar risks lacking formal mitigation programs. The FPA reports that Firewise communities complete millions of dollars in wildfire mitigation projects each year to reduce community-wide wildfire vulnerability.6
Still, resilient construction alone may not immediately improve pricing or increase capacity. Many carriers remain cautious about overconcentration in wildfire-prone areas following years of catastrophic losses. Instead, insurers are prioritizing portfolio stability and controlled aggregation management.
For agents and insureds, this means wildfire mitigation is becoming less of a recommendation and more of an underwriting expectation. Agents should also consider the potential impact of evolving building codes following a loss by discussing Ordinance or Law coverage with their clients. For homes that were not built to current code, the standard 10% Ordinance or Law coverage may be insufficient to cover the increased cost of rebuilding to today’s code requirements, making higher limits an important coverage consideration.
SECONDARY LIABILITY AND CASUALTY CONCERNS ARE GROWING
Wildfire exposure is no longer only a property insurance concern. Liability implications are becoming increasingly important as litigation activity and public scrutiny continue to grow after major wildfire events.
Questions surrounding vegetation management, building standards, emergency preparedness, and mitigation responsibilities may create additional exposures for municipalities, HOAs, developers, contractors, and property owners. Claims involving alleged failure to maintain defensible space or comply with evolving resiliency standards could become more common over time.
Smoke contamination, pollution-related claims, workplace safety concerns, and contractor liability may also create overlap between property, casualty, and environmental insurance exposures. As wildfire regulations continue evolving, carriers and insureds alike are paying closer attention to how resilience efforts may affect future negligence standards and litigation trends.
INSURANCE MARKETS ARE INCREASINGLY REWARDING MITIGATION
Insurance carriers are placing greater emphasis on proactive mitigation and engineering-based underwriting. In many cases, underwriters now require more detailed information about wildfire preparedness before offering terms.
Agents are increasingly being asked about:
- Roof construction materials
- Defensible space around structures
- Vegetation management practices
- Ember-resistant vents
- Closed versus open eaves
- Community mitigation programs
- Historical wildfire activity nearby
Submission strategy has also changed. Carriers want more than applications and loss runs. Underwriters increasingly expect agents to tell the story of the risk, including surrounding landscape conditions, elevation, weather patterns, wildfire history, and mitigation efforts.
Properties that fail to meet evolving resiliency expectations may eventually face reduced capacity, higher pricing, or limited market availability. At the same time, insureds who proactively invest in mitigation and resilient construction may position themselves more favorably during underwriting and renewal negotiations.
BOTTOM LINE
Wildfire resiliency regulations are changing the insurance landscape in real time. As states like Colorado implement stronger mitigation and construction standards, insurance carriers are reevaluating how they assess wildfire exposure, underwriting eligibility, and catastrophe aggregation risk. For insureds, agents, and property owners, wildfire mitigation is quickly becoming a critical component of long-term insurability and risk management strategy.
CRC Specialty helps retail agents navigate these evolving wildfire-related challenges with specialized knowledge, market insight, and access to CAT-focused insurance solutions. Our teams understand how underwriters evaluate wildfire exposure beyond mapping tools alone, helping agents position mitigation efforts more effectively during submissions and renewal negotiations. From layered property placements to emerging casualty and environmental exposures, CRC Specialty provides the strategic guidance and market access agents need to help clients adapt to today’s insurance environment.
