J ALLEN  CONSTRUCTION COMPANY: CUSTOM HOME BUILDERS IN FORT COLLINS

Planning to add square footage or gut a few rooms this year? The rules for how that work gets built have shifted. Colorado's new wildfire-resiliency requirements are rolling out across Larimer County in 2026, and the Fort Collins wildfire building code now touches everything from your roof covering to your exterior walls. If you're weighing a home addition , you'll want to know which parts of the code apply before the plans get drawn. Quick Answer: How the Fort Collins Wildfire Building Code Affects You If your property sits in a designated Wildland Urban Interface (WUI) zone, additions and significant alterations now have to meet Colorado's Wildfire Resiliency Code. In practice, that means Class A roof coverings, noncombustible gutters, ember-resistant vents, and, in higher-risk zones, ignition-resistant exterior walls. Larimer County's version took effect January 1, 2026, and local jurisdictions have to be in compliance by July 1, 2026. What Changed in 2026 Colorado adopted its first statewide wildfire building standard , and 2026 is the year it reaches homeowners. The Wildfire Resiliency Code Board adopted the code on July 1, 2025, then gave local governments until April 1, 2026, to adopt their own versions, with compliance starting July 1, 2026, or within three months of local adoption, whichever comes first. The timing isn't random. A wildfire north of Fort Collins in March 2026 forced evacuations and knocked out power to thousands, according to KUNC, a reminder that the wildland-urban interface isn't an abstraction in this part of the state. Larimer County moved early, adopting the 2025 Wildfire Resiliency Code with local amendments effective January 1, 2026. Nearby, the Loveland Fire Rescue Authority put its own 2026 code in place on April 21, 2026, per Loveland Fire Rescue Authority. This isn't the county's first recent code shift either; it follows the Larimer County 2024 building codes that already reset standards for local construction. For Fort Collins-area homeowners, the question isn't whether the code is coming. It's whether your lot falls inside a mapped WUI zone, because that decides how much of it applies to your project. How the Fort Collins Wildfire Building Code Affects Additions and Remodels Not every project triggers the full code. The threshold most homeowners hit is size: a significant alteration or addition exceeding 500 square feet can pull the work under the new requirements, per the code's adoption language. That's a real line. A modest bump-out might stay under it, while a primary-suite addition or a second story almost certainly won't. What the code asks for depends on your WUI fire intensity classification, which comes in three levels: Low, Moderate, and High. Low intensity zones require Class 1 measures: Class A roof coverings or assemblies, noncombustible gutters, and ember- and flame-resistant vents. Moderate and High intensity zones require Class 1 plus Class 2 hardening, including exterior walls built from noncombustible materials, fire-retardant-treated wood, or other ignition-resistant materials. Your classification is set by the wildfire risk map, not by how close you feel to open space, so two neighbors can land in different tiers. If you're already planning home renovation work that opens up the roof or exterior walls, folding these materials in during the same project costs far less than retrofitting later. The materials aren't exotic. Fiber-cement siding and Class A roofing are stocked locally and already sit on plenty of homes that have nothing to do with fire zones. Where your permit gets reviewed Who signs off depends on where you live. In the City of Loveland, the fire authority reviews WUI permits as part of the city process and charges a $400 fee on approval. In unincorporated Larimer County, those reviews go through the Larimer County Building Division directly. Confirm the reviewing body before you set a budget, because the review path affects both your timeline and your costs. What Most Coverage Misses About the WUI Map Most write-ups treat the code as if it blankets every home in the region. It doesn't. The trigger is the official wildfire risk map , not your ZIP code. Two houses on the same street can sit on opposite sides of a WUI boundary, and only one may owe Class 2 wall hardening. Before you assume your remodel is or isn't covered, pull up your jurisdiction's map and confirm your classification in writing. There's a second point coverage tends to skip. The code rewards work you were likely going to do anyway: a roof past its service life, siding due for replacement, an addition you've delayed. Each one is a chance to meet the standard at the margin instead of paying for a standalone retrofit down the road. Documented hardening can pay off on the insurance side too, since some Colorado insurers now factor mitigation work into their pricing. Handled right, a single project can check three boxes at once: more space, a tougher home, and a better position with your insurer. What Fort Collins Homeowners Should Do About the Wildfire Building Code The short version: find out if you're in a WUI zone, then plan around the 500-square-foot trigger before you commit to a scope. If you are covered, the smart move is to bundle the hardening into work you already had on the calendar, whether that's a remodel, an addition, or building a custom home from the ground up. Done that way, wildfire resilience becomes a line item instead of a separate, more expensive project later.

Colorado passed a law last year that changes how insurers are required to handle the mitigation work you do on your property. For homeowners in Fort Collins and Northern Colorado, home hardening upgrades now have a direct financial upside worth understanding before your next home renovation in Fort Collins . Quick Answer: What Home Hardening Fort Collins Homeowners Should Know Colorado HB25-1182, which takes full effect July 1, 2026, requires insurers to share your wildfire risk score, factor your documented mitigation work into their pricing, and offer discounts if they don't. Homeowners who have completed hardening improvements and aren't seeing it reflected in their premiums will have a legal right to appeal within 30 calendar days. What Colorado's New Wildfire Insurance Law Actually Requires HB25-1182 was signed on May 28, 2025, and takes full effect July 1, 2026, per the Colorado General Assembly . Before this law, insurers could use their own wildfire risk models without disclosing them to you or accounting for specific improvements you had made to your home. That changed. Under the law, your insurer must now: Provide annual written notice of your wildfire risk score and available mitigation discounts Incorporate property-specific mitigation actions into their pricing, or apply a discount if they don't Respond to your appeal within 30 calendar days if your documented work isn't reflected in your score The Colorado Division of Insurance (DORA) recommends documenting all mitigation work and discussing available discounts directly with your agent. What Home Hardening Fort Collins Projects Actually Look Like Home hardening focuses on the parts of your home most vulnerable to ember intrusion, which is the primary cause of structure ignitions in wildfire events, per Poudre Fire Authority . The upgrades that qualify under Colorado's framework fall into a few categories: Roofing and soffits: Class A fire-rated roofing materials and enclosed, screened soffits that block ember entry Siding and exterior walls: Non-combustible or ignition-resistant materials such as fiber cement, stucco, or treated wood composites Vents: Ember-resistant covers on attic, foundation, and crawlspace openings Decking and attachments: Fire-resistant decking materials and clearing combustibles from zones immediately adjacent to the structure If you're already planning exterior work, this is the most cost-effective window. Building to wildfire standards adds approximately 2.7% to construction costs when done as part of an existing project, per the Colorado Department of Fire Prevention and Control (DFPC). Tackling it as a standalone project means higher per-item costs and a second mobilization. What Most Homeowners Haven't Done Yet: The Free PFA Assessment Before committing to any scope of work, Fort Collins homeowners in the Wildland-Urban Interface can schedule a free, confidential Home Ignition Zone Assessment through Poudre Fire Authority. The one-hour visit identifies specific vulnerabilities and produces a written report you can share with your insurer and contractor to prioritize your project scope. PFA's Gold Letter Program goes further, providing official written verification of your completed mitigation work. That documentation carries direct weight with insurers reviewing your risk score under HB25-1182. Schedule by calling 970-416-2891 or emailing education@poudre-fire.org. What Fort Collins Homeowners Should Do About Home Hardening Now The law is in effect. Your insurer is required to respond to documented improvements. Start with the free PFA assessment to identify priorities, then address the highest-risk items through scheduled home maintenance or a planned exterior renovation. Bundling hardening upgrades with work you already need done keeps costs down and gets your documentation in order before your next renewal.
