Denver STR hosts: the $999/violation fines, felony risk, and how to stay compliant in 2026
March 14, 2026 · 10 min read · Updated with 2026 enforcement data

Denver is one of the strictest short-term rental markets in the United States. The city actively monitors over 25 booking platforms, pursues felony charges against hosts who lie about primary residence, and has achieved a roughly 90% compliance rate among listings — not through goodwill, but through enforcement that has real teeth.

If you're operating or considering an STR in Denver, here's what you're dealing with and how to stay on the right side of it.

What makes Denver different

Most cities have STR rules. Denver actually enforces them. The city's Department of Excise and Licenses uses a combination of third-party monitoring software, neighbor complaint investigations via 311, annual license audits, and property visits to identify non-compliant operators. Platforms like Airbnb are fined $1,000 for processing bookings on unlicensed properties — which means the platforms themselves are motivated to verify your license.

The result: Denver reports approximately 90% of active listings are properly licensed. The remaining 10% are the ones getting caught.

⚠ This is not hypothetical

Denver has pursued felony charges against hosts who claimed properties as primary residences when they didn't actually live there. The most well-known case involved a host who was charged with multiple felonies for operating several properties under false primary residence claims. If you can't truthfully prove you live in the property, do not apply for a Denver STR license.

The primary residence rule — and why it matters

This is the single most important rule to understand: only your primary residence can be a short-term rental in Denver. That means the property must be your usual place of return and the place where you actually live most of the year.

You must prove primary residence with at least two documents:

You can only hold one STR license in Denver — because you can only have one primary residence. This rule is specifically designed to prevent investors from buying multiple properties for STR use, and it's the rule Denver enforces most aggressively.

Can tenants operate STRs in Denver?

Yes — tenants can get an STR license for their rented primary residence, but they must meet all the same requirements and get written permission from their landlord via an affidavit.

Licensing: what you need and what it costs

Denver requires two licenses to operate an STR: a general business license and a Short-Term Rental license from the Department of Excise and Licenses.

Item Cost Notes
STR license (new) Up to $150 Capped by Colorado state law
Annual renewal $100 Required every 12 months — don't miss it
Liability insurance $1M minimum Must specifically cover STR activities
Lodger's Tax 10.75% City lodger's tax on all bookings
City sales tax 4.81% In addition to lodger's tax
Colorado state sales tax 2.9% Platforms may collect — you're still responsible for filing

Even when Airbnb or VRBO collects taxes on your behalf, you are still legally responsible for making sure everything is filed correctly. Maintain your own records — if there's a discrepancy in an audit, the liability falls on you.

Safety requirements

Denver requires all STR properties to pass safety standards. This isn't optional — your property must have:

New and renewing licenses may require updated safety inspections, and the city has increased random inspections in 2026.

Operational rules that get people fined

Beyond licensing, Denver enforces ongoing operational requirements that catch hosts off guard:

Your Denver STR compliance checklist

8 steps to full compliance
1.
Confirm primary residence. Can you truthfully prove you live at this property most of the year? If not, stop here — Denver is not a market for non-owner-occupied STRs.
2.
Gather residence documentation. Colorado driver's license, voter registration, tax returns, utility bills — you need at least two showing the property address.
3.
Get liability insurance. Minimum $1 million coverage that specifically covers STR activities. Your regular homeowner's policy likely doesn't.
4.
Install safety equipment. Smoke detectors, CO detectors, fire extinguisher. Do this before you apply — inspections happen.
5.
Apply for both licenses. General business license from Colorado Department of Revenue, plus STR license from Denver Excise and Licenses. Budget $150 for the STR application.
6.
Register for Lodger's Tax. Set up your account with Denver Department of Finance. You'll file even if platforms collect on your behalf — keep independent records.
7.
Add your license number everywhere. Every platform listing, your direct booking site, and a physical or digital display inside the property.
8.
Set a renewal reminder. Licenses renew annually ($100). Missing the renewal window means operating unlicensed — which means fines. Set a reminder 60 days before expiry.

Check your HOA before anything else

A city STR license doesn't override your HOA. Many Denver condo associations and HOAs prohibit short-term rentals entirely or impose minimum stay requirements. If your governing documents say no STRs, a city license won't save you. Check your CC&Rs before paying application fees.

What about investors?

Denver's primary residence rule means traditional STR investing — buying properties specifically for short-term rental income — is not viable in the city. You can only license the home you live in. If investor-model STRs are your strategy, look at other Colorado markets like mountain resort towns (with their own set of regulations) or consider a hybrid approach with 30+ day furnished rentals, which fall outside STR rules.
