Introduction to Short-Term Rentals in Denver

Denver, Colorado, stands as one of America’s fastest-growing cities, drawing millions of visitors annually for its thriving craft beer scene, proximity to world-class skiing, vibrant downtown district, and year-round outdoor recreation opportunities. The Mile High City’s appeal to tourists and business travelers has created significant demand for short-term rental accommodations, making it an attractive market for property owners looking to generate rental income.

From travelers heading to the Rocky Mountains to professionals attending conferences and events, Denver sees consistent demand throughout the year. The city’s strategic location as a gateway to Colorado’s outdoor recreation, combined with its robust business environment and cultural attractions, creates multiple revenue opportunities for STR operators.

However, Denver has implemented some of the most restrictive short-term rental regulations in Colorado. Unlike many markets that allow investment properties to operate as STRs, Denver permits only primary residences to be used for short-term rentals. This fundamental restriction, along with comprehensive licensing and compliance requirements, makes Denver one of the most challenging STR markets in the country for investors.

This comprehensive guide breaks down everything you need to know about operating a legal and compliant short-term rental in Denver in 2025, from the strict primary residence requirement to licensing procedures and ongoing compliance obligations.

Current Short-Term Rental Permit Requirements in Denver

Denver’s STR regulations, implemented in 2017, require multiple levels of licensing and strict compliance:

Primary Residence Requirement

The most fundamental requirement is that only primary residences can operate as short-term rentals in Denver. This means:

  • The property must be your usual place of return and where your habitation is fixed
  • You must live there for the majority of the year
  • Evidence required includes driver’s license, voter registration, tax documents, or utility bills
  • Investment properties and second homes are prohibited from STR use

Short-Term Rental License

  1. Initial Application Fee: $150 for new licenses
  2. Annual Renewal Fee: $100 (must be renewed before expiration to avoid late fees)
  3. License Validity: One year from issue date
  4. Processing Time: Initial review within 7 business days, full approval may take longer
  5. Application Method: Entirely online through Denver Permitting and Licensing Center

Required Documentation

To apply for an STR license, you must provide:

  • Colorado driver’s license or state ID showing the rental property address
  • At least two additional documents proving primary residence (voter registration, tax documents, utility bills)
  • Proof of property ownership or lease agreement with landlord permission
  • Lodger’s Tax ID from Denver Department of Finance
  • Liability insurance certificate showing minimum $1,000,000 coverage
  • Affidavit of primary residence signed under penalty of perjury

Lodger’s Tax Registration

Before applying for your STR license, you must:

  • Register for a Lodger’s Tax ID with Denver Department of Finance
  • This enables collection and remittance of the 10.75% lodger’s tax
  • Required even though platforms like Airbnb collect this tax automatically

Zoning Regulations for STRs in Denver

Denver’s zoning approach to STRs is relatively straightforward but strictly enforced:

Permitted Areas

Short-term rentals are generally permitted in residential zones, but only if the property is the host’s primary residence. This includes:

  • Single-family residential zones
  • Multi-family residential zones
  • Mixed-use zones
  • Most residential neighborhoods throughout the city

Key Restrictions

  • No investment properties – Non-owner-occupied properties cannot operate as STRs
  • One license per person – You can only have one primary residence
  • No corporate ownership – License must be in the name of a natural person, trust, or nonprofit
  • Accessory dwelling units (ADUs) can be rented short-term while host lives in main dwelling, but not vice versa

HOA Considerations

Many Denver properties are subject to HOA regulations that may:

  • Prohibit short-term rentals entirely
  • Require additional approvals or fees
  • Impose occupancy or noise restrictions
  • Mandate specific insurance requirements

Always verify both city regulations and any private HOA restrictions before operating an STR.

Required Documentation for Denver Short-Term Rentals

To operate legally and maintain compliance, keep these documents current:

  1. Short-Term Rental License: Must be renewed annually by expiration date
  2. Lodger’s Tax ID Certificate: From Denver Department of Finance
  3. Colorado State Sales Tax License: For additional tax obligations
  4. Liability Insurance Policy: Minimum $1,000,000 coverage specifically covering STR use
  5. Primary Residence Documentation: Driver’s license, voter registration, utility bills, tax records
  6. Property Ownership or Lease Agreement: With explicit permission for subletting if renting
  7. Safety Compliance Records: Documentation of required safety equipment
  8. Guest Information Brochure: Required to include emergency contacts and property information

License holders must display their license number on all rental listings and platforms to demonstrate compliance.

Denver Short-Term Rental Taxes

The tax structure for STRs in Denver involves multiple layers and rates:

Local Taxes

  • Denver Lodger’s Tax: 10.75% of gross rental receipts (collected automatically by major platforms)
  • Denver Sales Tax: 4.81% of gross rental receipts

  • Additional State Taxes: Various special district taxes may apply

Tax Collection and Remittance

  • Registering for all applicable tax licenses

  • Carbon Monoxide Detectors: Within 15 feet of bedrooms and 25 feet of fuel-burning appliances

Advice from Successful Denver STR Operators

Insights from experienced Denver short-term rental hosts:

“The primary residence requirement is strictly enforced. I know several people who had their licenses revoked for trying to claim properties as primary residences when they weren’t actually living there. Don’t risk it – it’s not worth the potential felony charges.” – Sarah M., 5-year Denver STR host

“The insurance requirement caught me off guard initially. My regular homeowner’s policy didn’t cover STR activities, so I had to get specialized coverage. It’s more expensive but absolutely necessary for legal compliance and peace of mind.” – Mike R., downtown Denver host

“Being a good neighbor is crucial in Denver. The complaint-based enforcement means one unhappy neighbor can shut you down. I always provide my contact information to neighbors and respond immediately to any concerns.” – Jessica L., Capitol Hill STR operator

“The tax compliance is complex but manageable if you stay organized. I use accounting software specifically for STRs and work with a local accountant who understands Denver’s requirements. The quarterly filings are worth getting professional help.” – David K., 3-year Denver host

The consensus among successful operators is that Denver rewards hosts who strictly follow regulations and maintain positive community relationships.
