Colorado STR Laws in 2026. A Market-by-Market Guide for Investors in the Rocky Mountains

Colorado does not have a statewide short-term rental law. No preemption. No uniform framework. The state legislature authorized counties to regulate STRs in 2020 with HB 20-1093, but the actual rulemaking lives with each individual municipality.

For investors eyeing Colorado’s mountain markets (and based on summer 2026 booking trends, a lot of you are), this means your due diligence begins with one question: what does this specific town allow me to do with this property?

I have reviewed the ordinances for seven of Colorado’s most active STR mountain markets. Here is the market-by-market breakdown.

This article provides general information and should not be construed as legal advice. Consult a qualified attorney in your jurisdiction for advice specific to your situation.

Why Colorado’s Patchwork Matters More Than You Think

Most states either preempt local STR regulation (like Idaho’s HB 583 or Indiana’s HEA 1210) or stay silent and let cities handle it. Colorado is firmly in camp two. The result: two towns 30 miles apart can have completely different rules on licensing, caps, occupancy, and transferability. You need to know the specific ordinance for the specific town where you plan to buy.

Aspen: Cap-and-Waitlist, Not a Lottery (But Still Restrictive)

Let me clear up a common misconception first. Aspen does not use a lottery system for STR permits. That proposal (Ballot Question 300, which would have capped permits at 400 and distributed them by lottery) went to voters and failed, with roughly 58% voting against it.

What Aspen does use is arguably just as restrictive for investors. Under Ordinance No. 9 (Series 2022), the city created three permit categories:

STR-C (Classic Permit): The permit non-owner-occupied investment properties need. Capped by zone district at 75% of the permit count that existed when the ordinance was drafted. The R-MF (residential multifamily) zone has the highest cap at 190 permits. Some zones (R-3, R-30) allow just one. Cap full? You go on a waitlist. The fee is $394 (nonrefundable).

STR-OO (Owner-Occupied): For Aspen residents who own and live in the property. Not capped by zone, but limited to 120 rental nights per year.

STR-LE (Lodging Exempt): For established lodge and condo-hotel properties. Not capped.

Here is the part that really matters for investors: STR permits in Aspen are not transferable upon sale. Buy a property with an active STR-C permit, and that permit terminates at closing. You then need to apply fresh, and if the zone cap is full, you join the waitlist. In a market where condos regularly sell above $1 million, that is a risk factor many buyers overlook. Permits must also be renewed annually (November 15 through January 14), and properties that filed $0 in tax revenue during the prior year are ineligible.

Investor bottom line: Aspen is not closed to STR investment, but the barriers are high enough that buying a property and assuming you will get a permit is a dangerous strategy. Know which zone you are buying into, check the current cap and waitlist status, and price the regulatory risk into your acquisition.

Vail: High Fees, Insurance Requirements, No Published Caps

Vail requires a Short-Term Rental License for any rental of 30 days or less. No published cap on total licenses, but the fee structure does the gatekeeping. The regulatory fee is $1,200 per bedroom per year. A four-bedroom ski house pays $4,800 annually before cleaning, management, or maintenance. Add the $1 million liability insurance requirement, and the operating cost floor is meaningfully higher than most Colorado markets. Licenses expire February 28 and require annual renewal.

Investor bottom line: Vail is accessible to investors who can absorb the fee structure. The per-bedroom model means smaller units (studios, one-bedrooms) have a much more favorable cost-to-revenue ratio than large chalets. Run your numbers accordingly.

Breckenridge: Zone-Based Licensing with Serious Per-Bedroom Costs

Breckenridge established its zone-based licensing system in 2021, restricting where STRs can operate and how many are permitted in each area. StaySTRA data shows 5,008 active rentals in the Breckenridge market, with a $339 average nightly rate and 46.4% annual occupancy.

The licensing cost has two components: a Business and Occupational License Tax (BOLT) ranging from $75 for a studio to $175 for four or more bedrooms, plus a regulatory fee of $756 per bedroom per year with no cap. A three-bedroom property pays $2,268 in regulatory fees alone, plus the BOLT.

Occupancy limits are set at 2 persons per bedroom plus 4 additional persons total (studios are limited to 4 persons). Every licensed property must designate a Responsible Agent who is available 24/7 and can respond to complaints within 60 minutes via the town’s STR Complaint Hotline.

Like Aspen, Breckenridge ties the license to the owner, not the property. When you sell, the license does not transfer. The new owner must apply fresh.

Investor bottom line: Breckenridge is one of the most active STR markets in the Rockies, and the $339 average nightly rate reflects strong demand. But the per-bedroom fee structure and non-transferable license mean your exit strategy needs to account for the fact that buyers cannot assume STR continuity. Use the StaySTRA Breckenridge analyzer to model revenue against the full regulatory cost stack before committing.

Denver: Primary Residence Only

Denver’s rules are straightforward: short-term rentals must be the host’s primary residence. One residence per person, you must actually live there, and you prove it with documentation (driver’s license, voter registration, tax return address). StaySTRA data shows 3,760 active STR listings in Denver at $212 average nightly rate and 54% occupancy. Licensing is modest ($100 annual plus $50 application fee), but the primary residence rule means this is a house-hacking model, not a pure investment play. The city has revoked licenses when primary residence status was misrepresented.

Investor bottom line: Denver works for owner-occupants who want to rent their home while traveling or rent a portion of it (like a basement unit). It does not work for remote investors or anyone building a portfolio of non-owner-occupied rentals.

Telluride: Ownership Caps and Rental Frequency Limits

Telluride takes a different approach than the permit-cap model. In residential zone districts, a property can be rented short-term (under 30 consecutive days) a maximum of three times per calendar year. That is not three months. That is three separate rental periods. For an investor banking on high-frequency bookings during ski season and summer, this is a meaningful constraint.

Picture this: you buy a condo in a Telluride residential zone expecting weekly turnovers during ski season. After your third booking of the year, you are done until January 1. Three bookings per year is nowhere near enough to support a standard STR investment thesis.

Telluride also caps ownership at two STR-licensed units per person, LLC, trust, or corporate entity. Every property needs a Town of Telluride business license with the number displayed in all advertising.

Investor bottom line: Telluride’s rules are workable if your property is in a commercial or accommodation zone. In residential zones, the three-rental-per-year cap effectively kills the traditional STR model. Zone classification is everything here. Check it before you make an offer.

Steamboat Springs, Durango, and Estes Park: Lighter Touch, But Not Unregulated

These three markets get grouped together because their regulatory frameworks share a common trait: they permit STR investment more broadly than the markets above but still require licensing, zoning compliance, and tax collection.

Steamboat Springs uses a green/yellow/red overlay zone map (adopted June 2022) that determines where STRs can operate. Enforcement has been aggressive: fines up to $2,650 per violation per day, plus a two-year operating ban for violations. Some property owners have been “blindsided” by enforcement actions, and City Council is reconsidering whether the policy needs reform.

Durango requires a Limited Use Permit (LUP) before you can advertise or operate. STRs are only permitted in certain zones (Central Business, Mixed-Use, EN-1, EN-2), and the EN-1/EN-2 zones have caps. Operators need a city business license and must collect lodgers’ and sales taxes.

Estes Park requires a Vacation Home License with occupancy limits of 2 per bedroom (8 max). Operators must collect and remit sales taxes. Of the three, Estes Park has the lightest framework, though proximity to Rocky Mountain National Park keeps demand and prices elevated.

Investor bottom line: All three markets are accessible to investors, but “lighter touch” does not mean “no rules.” Steamboat’s enforcement posture is a cautionary tale. Durango’s zone restrictions matter. Estes Park’s occupancy limits constrain revenue on larger properties. None of these is a free-for-all.

Colorado Mountain Markets: Regulatory Comparison Table

How to Evaluate Regulatory Risk Before You Buy in Colorado

I have reviewed hundreds of local STR ordinances across the country (yes, I count that as a hobby, and yes, my friends find it concerning). Colorado’s patchwork is denser than most states, but the evaluation framework is consistent. Before you make an offer on any Colorado mountain property, answer these five questions:

1. What zone is the property in? In Breckenridge, Steamboat, Telluride, and Durango, zone classification determines whether you can operate at all. Do not rely on the listing agent’s understanding. Pull the zone designation yourself.

2. Is there a cap or a waitlist? Aspen’s zone caps and Durango’s EN-1/EN-2 limits both apply. Most Colorado mountain town permits do not transfer on sale, so confirm availability before closing.

3. What are the total annual regulatory costs? The difference between Estes Park’s license fee and Vail’s $1,200-per-bedroom charge is enormous. Model these into your pro forma. The StaySTRA DSCR market analysis can help identify which markets pencil out for leveraged investors.

4. How aggressive is enforcement? Steamboat has shown that even permissive-on-paper markets can be punishing when enforcement ramps up. Our STR enforcement reality guide covers how cities are actually making their ordinances stick.

5. What is the political trajectory? Aspen’s failed ballot measure shows voters rejected the most extreme restriction, but council still implemented caps. Steamboat’s enforcement backlash could lead to reforms. Direction matters as much as current rules.

Run the Numbers Before You Run the Listing

Colorado’s mountain markets offer strong ADR potential (Breckenridge averages $339/night, Denver $212), but the regulatory environment shapes what that demand is worth to you. Use the StaySTRA analyzer for Breckenridge (or any Colorado market) to model revenue against the full cost stack. The numbers tell you whether a deal works. The ordinance tells you whether you are allowed to try.
