Wildfire Season Is a Business Risk Every Facility Manager and CRE Executive Must Understand in 2026

Wildfire season is becoming a familiar part of the operational calendar for many regions in North America. Once viewed mainly as an environmental issue, it now has measurable implications for how commercial portfolios are insured, maintained, and valued.

In 2024 alone, North America experienced over 63,000 recorded wildfires, burning more than 18 million acres across the U.S. and Canada — nearly double the 10-year average (Natural Resources Canada). The resulting smoke affected air quality in major cities from Vancouver to New York, prompting building closures and driving short-term spikes in maintenance and HVAC energy use.

For facility managers and CRE executives, these events have introduced a new operational reality. Wildfire smoke is now considered a top indoor air quality (IAQ) concern, and insurers increasingly evaluate regional fire exposure when assessing coverage or renewal terms. At the same time, investors are beginning to factor climate resilience into asset valuation, positioning air quality and building performance as indicators of long-term stability.

Why Wildfire Risk Now Belongs in Business Planning

Wildfires are increasing in both frequency and intensity faster than infrastructure can adapt. The U.S. Department of the Interior’s new $6.55 billion budget for the U.S. Wildland Fire Service underscores that this is now a national-scale operational and economic issue (DOI).

Suppression costs alone are projected to rise significantly in the coming decades. A U.S. Forest Service analysis estimates that median annual wildfire suppression spending (adjusted for inflation) could increase 42% by 2050, reaching approximately $3.9 billion under moderate climate scenarios (USDA Forest Service).

Yet suppression is only part of the picture. The U.S. Joint Economic Committee estimates that climate-exacerbated wildfires now cost the U.S. economy between $394 billion and $893 billion each year, accounting for property losses, business disruptions, health impacts, and insurance effects (JEC Senate Report, 2023).

The Insurance Ripple Effect

Insurance markets are already pricing wildfire exposure into underwriting. Tools like CAPE Wildfire Intelligence use AI, geospatial imagery, and hazard modelling to assign structure-level and property-level wildfire risk scores, enabling underwriters to reassess coverage based on exposure rather than just past claims. (CAPE Analytics)

Across wildfire-prone regions such as California, Colorado, and British Columbia, portfolio owners are seeing concrete changes:

• Coverage exclusions or higher deductibles in fire and smoke perils

• Non-renewals in high-risk zones, especially near the wildland–urban interface (Carnegie Endowment, NAIC, Federal Reserve Bank of Dallas)

• Downward pressure on valuations, as appraisers and lenders penalize assets lacking insurability

  
  

Importantly, the value impact isn’t always tied to physical damage. Research shows that properties that remain intact may nonetheless trade at discounts purely because of perceived risk. A PLOS One study finds that in wildfire-affected areas, undamaged homes can experience price declines, which is a phenomenon seen across multiple wildfires. (PLOS)

How Wildfire Smoke and Heat Affect Buildings

Wildfires threaten buildings in two main ways:

1. Direct ignition happens when flames, embers, or radiant heat reach combustible materials on or near a building, such as wooden roofs, vents, or façades. Once ignited, fire can spread through exterior assemblies or debris around the structure.

2. Indirect infiltration occurs when smoke, ash, and fine particulate matter (PM₂.₅) enter the building envelope through HVAC systems, air intakes, doors, windows, or gaps in the façade.

   
   

Even high-performance, well-sealed buildings are not fully protected. Research from the U.S. Environmental Protection Agency (EPA) and the National Institute of Standards and Technology (NIST) shows that during severe wildfire smoke events, indoor particle concentrations can reach 30–75% of outdoor levels depending on the building’s ventilation rate and filter performance (EPA Smoke Ready Buildings Guide, 2023; NIST Technical Note 2227, 2021).

This infiltration also increases filter loading, raises fan energy use, and accelerates wear on HVAC components. For facilities teams, that means higher operational costs, potential compliance challenges with occupational exposure standards, and growing scrutiny under ESG and indoor environmental quality reporting frameworks.

Practical Steps for Building Wildfire Resilience in 2026

1. Understand Your Exposure

Start by building a clear picture of your portfolio’s landscape. A simple risk overview can go a long way. Use publicly available wildfire hazard maps, vegetation data, and local topography to see where your buildings sit in relation to fire-prone areas. Combine this with maintenance records or site inspections to identify where small improvements, like clearing debris or updating rooftop materials, can reduce exposure.

Then, model a few realistic “what-if” scenarios that reflect operational impact rather than catastrophe:

• A few days of poor outdoor air quality require HVAC adjustments

• Temporary power interruptions during peak cooling season

• A change in insurance terms for one or two properties

Understanding these variables early helps leaders plan with clarity, not urgency. When resilience is quantified, it becomes part of sound financial management.

2. Strengthen Buildings for Smoke and Fire Resilience

Wildfires can’t be stopped, but their side effects can be managed. Many practical upgrades that support energy efficiency also improve wildfire resilience:

• Ember-resistant vents and non-combustible roofing materials

• Fire-rated windows and insulated façades

• High-efficiency air filtration (MERV-16 or HEPA)

• Smart ventilation controls that respond automatically to outdoor air quality data

These measures don’t have to happen all at once. They can be phased in as part of scheduled retrofits. In HVAC systems, modern low-pressure filtration technologies, such as electromagnetic filtration systems developed by Blade Air, allow facilities to maintain clean indoor air without overworking fans or consuming excess energy. The result is stronger air quality performance and lower long-term operational costs, even when outdoor conditions fluctuate.

3. Keep Teams Prepared and Systems Ready

A clear process is just as valuable as physical upgrades. Establish simple guidelines for when to adjust air systems or communicate with tenants, and make sure every technician knows where to find them.

For example:

• At what air quality index (AQI) should your system shift to recirculation?

• Who needs to be notified if conditions worsen?

• What’s the best way to reassure tenants or staff?

Most preparation is about timing and awareness. Scheduling seasonal filter checks, cleaning air intakes, and confirming that sensors and vents are working properly can prevent issues long before smoke season begins.

4. Use Insurance as a Collaboration Tool

Insurers are moving toward data-driven resilience verification, which can work to your advantage. Buildings that can show documented improvements, such as upgraded filtration or defensible space compliance, often receive better consideration at renewal.

Keep the essentials organized:

• Maintenance and inspection logs

• Before-and-after photos of retrofits

• Notes on how air quality is monitored and reported

Sharing this information proactively not only helps maintain coverage but also demonstrates a high level of operational maturity to investors and stakeholders.

5. Strengthen Community and Utility Partnerships

Resilience extends beyond your own building. Coordinating with neighbors, local fire departments, and city officials helps ensure that your mitigation work complements the broader community response.

Some organizations are exploring microgrids and on-site energy storage to maintain power when utilities shut down during high-risk conditions (arXiv Energy Systems Study). These projects often start small, with critical loads or backup systems, and can scale over time.

The more connected a facility is to its surrounding network, the faster it can recover and return to normal operations after a smoke event or disruption.

Shift From Response to Readiness

Wildfire has evolved from an emergency event to a strategic performance metric.

For CRE portfolios, this means:

• Wildfire exposure is now a factor in valuation and underwriting

• Insurability defines asset liquidity

• Indoor air quality performance influences tenant retention and ESG scores

The most forward-thinking leaders are reframing resilience as an investment class. One that safeguards people, stabilizes operations, and drives measurable financial continuity.
