A Single Unpermitted Rental Can Cost You $394 and Your License
In Aspen, Colorado, the stakes for short-term rental non-compliance are immediate and financial. Fines range from $148 to $394 per violation, and even a single unpermitted rental night can trigger enforcement action. The city actively monitors compliance under a high-enforcement posture, and repeat violations can escalate to administrative hearings and outright permit revocation. With Aspen's median property values among the highest in the country, the income potential from STRs is enormous, but so is the regulatory exposure for operators who skip the paperwork.

One critical tax detail: Airbnb collects and remits lodging tax on behalf of Aspen hosts, but VRBO does not. That means VRBO operators must manually calculate, collect, and remit lodging taxes to the city every month. The tax submission portal is maintained at aspen.gov.
Regulatory Context: The Full Rule Set in Aspen
Aspen's STR framework is built on three interlocking requirements: a business license ($150 annually), a vacation rental permit, and ongoing tax compliance. Neither the license nor the permit is optional, and both must be in place before the first guest checks in.
The permit system is divided into three categories, each with distinct eligibility and night caps:
- Owner-Occupied Permits: Apply to primary residences. Capped at 120 rental nights per year. Owners must occupy the property as their primary residence.
- Classic (Non-Owner-Occupied) Permits: Designed for second homes and investment properties. May allow unlimited rental nights depending on zoning, but subject to neighborhood-level caps. Individual unit owners at lodge or condo-hotel properties must apply under this category.
- Lodging-Exempt Permits: Apply to condo-hotels and lodge-style properties. Not subject to nightly limits.
Occupancy is calculated on a per-bedroom basis: 2 occupants per bedroom plus 2 additional guests, with a hard cap of 8 total guests. Studio units are limited to a maximum of 3 occupants.
Physical compliance requirements are equally demanding. Properties must pass a building code inspection before receiving a permit. Specific safety requirements include:
- Smoke detectors in all sleeping areas and on each level of the property
- Carbon monoxide detectors in all sleeping areas
- Fire extinguisher on premises
- Egress windows meeting local code
- Fire suppression systems where required by building code
Operators must also post house rules, emergency contacts, and safety information visibly inside the property. A local contact must be designated and reachable. Insurance coverage is required. The full building code standards are published at aspen.gov/1384.
Permits are not transferable when a property changes ownership. A buyer purchasing an actively rented property must reapply from scratch, with no guarantee of approval, particularly given the frozen permit status and active waitlists in many residential zones.
What Changed and Why
Aspen's current STR framework is anchored in Ordinance No. 9, Series 2022, which introduced the business license requirement alongside the vacation rental permit structure. The ordinance was designed to accomplish two goals: improve tax collection from STR operators and bring unlicensed rentals into a formal compliance structure.
Subsequent amendments to the regulations were approved to streamline the permit application process and enhance compliance monitoring. A moratorium on the issuance of certain residential building permits was also implemented, though that specific moratorium was set to expire on August 8, 2022. The permit system remains frozen as of May 2026, with waitlists active across multiple residential districts.
The caps on STR permits across residential zones were introduced in direct response to concerns about housing availability, neighborhood character, and overall livability. Aspen, like many high-demand resort markets, faces tension between the economic value of short-term rentals and the displacement pressure they create on long-term housing stock. The three-tier permit system and neighborhood-level caps are the city's primary tools for managing that tension.
Pending regulatory changes were flagged as of April 14, 2026, signaling that additional amendments may be in progress. Operators should monitor the city's official channels for updates.
What Operators Must Do Now
If you are currently operating or planning to operate an STR in Aspen, the following steps are not optional. Each carries a specific compliance requirement and, in most cases, a financial penalty for non-compliance.
- Obtain a business license before accepting any bookings. The fee is $150 annually. Apply through the City of Aspen's business licensing process. Operating without one exposes you to fines starting at $148 per violation.
- Apply for the correct STR permit category. Determine whether your property qualifies for an Owner-Occupied, Classic, or Lodging-Exempt permit. Review the ordinance at municode.com. Note that the permit system is currently frozen with waitlists in many zones. Do not assume availability.
- Schedule and pass a building code inspection. Inspection is required before a permit is issued. Ensure smoke detectors, CO detectors, fire extinguishers, egress windows, and fire suppression systems are in place and meet code. See requirements at aspen.gov/1384.
- Register for lodging and sales tax collection. Register at aspen.gov/1392. If you list on VRBO, you must manually collect and remit the 2.4% local lodging tax monthly. Airbnb handles this automatically, but you remain responsible for confirming remittance. The combined tax burden including state and local rates reaches 13.7%.
- Post required disclosures inside the property. House rules, emergency contacts, and safety information must be physically posted inside the rental. Designate a local contact who can respond to issues. Confirm your insurance policy covers short-term rental activity.
- Renew your permit and license annually. Neither is permanent. Permits do not transfer to new owners on sale. If you are purchasing a property with an existing STR operation, budget time and uncertainty into your acquisition plan for the reapplication process.
Bottom Line
The cost of full compliance in Aspen starts at $150 for the business license, plus inspection costs, insurance, and the time investment of navigating a frozen permit system with active waitlists. That is a manageable upfront cost relative to the nightly rates Aspen commands. The cost of non-compliance is a different calculation entirely: fines of $148 to $394 per violation, potential permit revocation, back taxes owed on a combined rate that can exceed 13%, and the legal exposure of operating an unlicensed rental in a high-enforcement market. For property owners who purchased assuming rental income would offset carrying costs, discovering mid-ownership that a permit is unavailable or that an unpermitted rental has triggered enforcement is a serious financial event. The due diligence happens before the purchase, not after the first booking.
