The state splits between mountain resort markets, led by Vail, Breckenridge, and Aspen, and the Denver metro. Resort properties carry extreme revenue seasonality: a ski-week booking can be worth multiples of a shoulder-season week, which matters enormously when a loss takes the property offline.
What underwriters ask forWildfire changed everything. The 2021 Marshall Fire destroyed roughly a thousand homes in suburban Boulder County, in grassland most models treated as low risk, and carriers responded statewide. Most now require current defensible-space and mitigation documentation, and elevation drives pricing directly, with properties above 10,000 feet commanding substantial surcharges. Snow-load and freeze protocols are standard questions for high-country homes.
Wildfire claims are denied when defensible-space records are missing or stale. The quieter loss is business income: payouts are routinely capped at shoulder-season equivalents rather than the peak ski-week revenue the owner actually lost, because the policy was never structured to reflect the property’s real earnings curve. That gap is invisible until the worst possible moment.
Colorado keeps licensing almost entirely local; the main statewide lever is tax, and the legislature has repeatedly debated reclassifying high-use STRs as commercial property, a change that would flow straight through to entity structure and economics. On the ground the rules are strict in the populated markets. Denver and Boulder effectively limit short-term rentals to an owner’s primary residence, with Boulder capping rentals near 120 nights a year and requiring the owner to live there most of the year. The resort towns regulate through permits and inspections: Vail’s ordinance requires fire-department inspections and proof of insurance, and Longmont requires an annual permit plus proof of coverage sufficient to operate. Confirm the local rule, and any insurance condition, before you buy.
