Mt. Crested Butte's Rental License Has No Cap. Colorado's New Tax Law Doesn't Care.

How much does it actually cost to run a short-term rental in Mt. Crested Butte this year? Ask that question to five people shopping for an investment property in the valley and most will answer with a license fee. The real number lives somewhere else entirely, in a state law that took effect for the 2026 property tax year and doesn't care what your local town code says about caps or zoning.

Here's the setup buyers keep repeating to themselves: Mt. Crested Butte has no limit on short-term rental licenses and no zoning restrictions on where you can operate one. Downtown Crested Butte, a few miles south, capped its Unlimited License program years ago and now works new applicants through a waitlist once that cap fills. So the logic goes: buy in Mt. Crested Butte, skip the waitlist, start renting. That comparison is accurate as far as it goes. It just answers the wrong question for anyone buying a property specifically for rental income in 2026.

The License Comparison Everyone Already Makes

The Town of Mt. Crested Butte's short-term rental program, in place since 2020, currently has no cap on the number of licenses it issues and no zoning restrictions on where an STR can operate. The license runs $400 for the calendar year, covers one dwelling unit, and requires a local representative within a 45-minute drive. That's the entire structural ceiling. Buy a qualifying property, apply, pass the inspection, rent it as many nights as you want.

Crested Butte town, a few miles down the road, splits its licensing into two tracks. A Primary Occupancy License, for an owner who lives in the home at least six months a year, has no cap on how many get issued but limits rental use to 90 nights a year. The Unlimited License, built for owners who don't live in the property, allows rental every night of the year but is capped at 30 percent of the town's free-market residential units, which works out to a hard ceiling of 198 licenses, isn't transferable when a property sells, and requires the owner to rent at least 30 nights a year or lose it. Town council materials from 2025 show 189 of those 198 Unlimited Licenses already issued, alongside 23 Primary Occupancy Licenses, leaving little room before a new applicant lands on the waiting list that kicks in once the cap fills.

Side by side, the two towns look like a simple trade: flexibility in Mt. Crested Butte, scarcity in town.

That table answers "where can I get a license fastest." It says nothing about what the state now does to your property tax bill once you have one.

What Colorado's New Tax Law Actually Tests For

House Bill 24-1299 took effect for property tax years beginning January 1, 2026. It defines a "commercial short-term rental unit" as one that is not the owner's primary or secondary residence and, if that unit was rented short-term for more than 90 days in the prior tax year, the county assessor reclassifies it as lodging property, a nonresidential subclass valued using the market approach, the same method applied to hotels and motels rather than houses.

The financial gap between those two classifications is not small. Colorado's residential assessment rate sits in the neighborhood of 6.7 to 6.95 percent. Lodging property has been assessed closer to 27 to 29 percent, roughly four times as much on the same appraised value. A property that gets reclassified doesn't just owe more, it owes more against a valuation method built for a hotel, not a house.

The law runs on a paper trail, not a handshake. Every year by November 15, an owner of a short-term rental unit must sign and submit an affidavit to the county assessor stating whether the property will continue operating as a short-term rental into the next tax year and whether it qualifies as the owner's primary or secondary residence. Absent information to the contrary, the assessor uses that affidavit to decide whether the unit counts as a commercial short-term rental unit, and a commercial unit that cleared more than 90 rental nights in the prior tax year gets classified as lodging property. The next filing deadline is November 15, 2026, a little over two months from today.

Notice what the law does not ask about. It never mentions which town issued your rental license, whether that town has a cap, or what zone the property sits in. It asks two things only: is this your primary or secondary home, and did it clear 90 rental nights last year.

Why "No Cap" Doesn't Buy You Any Protection

This is where the Mt. Crested Butte comparison stops being reassuring. A license with no limit on rental nights is exactly the kind of license most likely to produce a calendar that clears 90 nights in a normal year between ski season and summer, which is the entire point of buying there for income in the first place. Nothing in the town's program creates a reason to stop short of that number. There's no local mechanism pushing an owner toward primary-residence status, no night cap that happens to land under the state's threshold, nothing that functions as an accidental guardrail.

Crested Butte town's Unlimited License track has the same exposure, worth being clear about. It also allows unlimited rental nights, so an investor holding one of the 198 available Unlimited Licenses in town faces the identical 90-day test under state law. The only Crested Butte license genuinely insulated from this is the Primary Occupancy License, capped at 90 nights a year, but that path already requires the owner to live in the home at least six months annually, which means the property likely qualifies for the primary-residence exemption regardless of night count. That license was never really competing with an investment purchase to begin with.

Strip away the town-by-town framing and what's left is a single statewide test that applies the same way whether the property sits in Mt. Crested Butte, downtown Crested Butte, or anywhere else in Gunnison County. License availability decides how fast you can start renting. It has no bearing on how the assessor values what you own once you do.

The Diligence Question That Actually Matters Now

For a buyer running the numbers on an income property in Mt. Crested Butte this year, the useful question isn't which town's license is easier to get. It's whether the specific unit under contract will function as a genuine secondary residence for you or purely as a rental, and what a realistic calendar of nights looks like against the 90-day line. A property that pencils out at 100 rental nights under the old assumption of a flat residential tax rate needs to be re-run against a lodging-property assessment before the offer goes in, not after the first reclassification notice arrives.

It's also worth building the November 15 filing into whatever ownership calendar you keep, alongside HOA dues and lift ticket renewals. Missing that affidavit doesn't make the classification question disappear. It just means the assessor makes the call without your input.

A Few Questions We Hear Often

Does this apply to a property I only rent occasionally? The 90-day threshold is specific. A property rented short-term for 90 days or fewer in the prior tax year stays classified as residential, whatever town it's in.

Does using the home myself part of the year change anything? Yes, if it qualifies as your primary or secondary residence, the commercial classification doesn't apply regardless of rental nights, since the definition of a commercial short-term rental unit excludes primary and secondary residences outright.

Does my town's license type affect my property tax classification? No. The state law runs independently of local licensing. A license controls whether you can legally rent. The affidavit and the assessor's night count control how the property gets taxed.

When is the next deadline? November 15, 2026, for the annual affidavit filed with the Gunnison County assessor.

Numbers like these are exactly why a second look before you write an offer pays for itself. If you're weighing a rental property in Mt.
