Understanding the Denver Rental License

Last updated: January 2026. In Denver, operating a residential rental property requires a specific business license from the City and County. This regulation, mandated by a 2021 ordinance, establishes two distinct tracks [1][2]. A Residential Rental Property (RRP) license is required for any lease of 30 days or more [6]. For stays under 30 days, a Short-Term Rental (STR) license is needed, but it is restricted to the host's primary residence [3][7]. Operating without the correct Denver rental license is illegal and can trigger enforcement, including fines that were increased to up to $5,000 per violation as of late 2025 [4][10]. For a complete breakdown of requirements and costs, see our Denver Rental License Guide.

The Residential Rental Property (RRP) License for Long-Term Rentals

For Denver landlords renting properties for 30 days or more, a Residential Rental Property (RRP) license is mandatory. This specific Denver rental license is valid for four years and requires a one-time $50 application fee plus a $195 inspection fee [2][6]. The core requirement is a third-party inspection using the city's official checklist, which covers critical safety items like smoke detectors, egress windows, and GFCI outlets.

The inspection process varies by property type. For example, a single-unit home requires a full inspection, while multi-unit buildings require 10% of units to be inspected [8]. New applications must be submitted within 90 days of the inspection, and renewals must be started 90 days before the license expires, requiring a new inspection each cycle. Exemptions exist for new construction under four years old, which can submit a Certificate of Occupancy instead, and for certain affordable housing units [3].

Compliance deadlines were phased in: multi-family buildings needed this license by January 1, 2023, and single-family homes were required to obtain it by January 1, 2024 [2][5]. Once licensed, landlords must include their license number in all advertisements and provide the official Denver Tenant Rights & Resources notice to tenants at lease signing. For a detailed breakdown of costs and steps, review our Denver Rental License Process. Navigating these requirements can be complex; professional services can ensure a smooth and compliant application, helping you avoid penalties and operate with confidence.

The Short-Term Rental (STR) License for Primary Residences

Denver's Short-Term Rental license is a specific business permit for renting out a residential property for stays under 30 days, but it comes with strict eligibility rules [1]. This license is only available for a host's primary residence, which you must prove with a Colorado driver's license and two additional proofs of residency. If you are a tenant hosting, you must also provide a landlord consent form.

Mandatory requirements for this Denver rental license include maintaining at least $1 million in liability insurance or using a platform that provides equivalent coverage. You must also designate a local responsible party, provide a city-mandated brochure to all renters, and register for both the Lodger's Tax and Occupational Privilege Tax (OPT) [3]. The license number must be displayed in all advertisements, and overlapping bookings are prohibited.

If the property is not your primary residence, you are not eligible for an STR license. In that case, operating short-term stays typically requires a Lodging Facility license, which involves complex zoning changes and potential building code upgrades for fire safety and accessibility [3]. For a primary residence, the STR license must be renewed annually. Navigating these specific rules is crucial for compliance; professional services like those offered through our Denver rental licensing page can help streamline the entire application and ongoing management process.

RRP vs. STR: Key Differences in Denver Rental Licensing

License Type Eligible Property Term / Renewal Key Requirements Tax Obligations
Residential Rental Property (RRP) Any property rented for 30+ consecutive days [1]. 4-year license; renewal requires a new inspection ~90 days before expiration. Third-party inspection using city checklist; no explicit liability insurance mandate in the license rules. Standard income tax reporting; no special Denver lodging tax is triggered.
Short-Term Rental (STR) Operator's primary residence only for stays under 30 days (operationally, under 29 nights). 1-year license; must be renewed annually. $1 million liability insurance, local responsible party, renter brochure, and license number in all ads. Must register for and file Denver Lodger's Tax and Occupational Privilege Tax (OPT).

The core difference lies in the rental period and property use. An RRP license, required for traditional leases, is a four-year permit focused on housing safety via a qualified inspection [2]. In contrast, a short-term rental license is an annual permit for a host's own home, with heavy emphasis on insurance and tax compliance [3]. For example, while both require displaying a license number in advertisements, only the STR path mandates proof of $1M coverage. This means choosing the correct Denver rental license depends entirely on your rental model. Recent enforcement efforts highlight the importance of proper licensing, as operating without one can lead to significant fines [4].

Navigating these distinct paths can be complex. For detailed guidance on the inspection process for a residential property license, see our Denver Rental License Inspection Overview.

Common Pitfalls and How to Avoid Them

Navigating Denver's rental compliance can be complex, and common missteps lead to fines or delays. Here are key pitfalls and how to avoid them.

  1. Missing the 90-day window. Your third-party inspection for a Residential Rental Property (RRP) license is only valid for 90 days. Submitting your application after this window closes means paying for a new inspection. Plan your timeline carefully to avoid this costly error.
  2. Misapplying for an STR license. A Short-Term Rental (STR) license is a permit only for a host's primary residence. Attempting to use this path for an investment property is a violation; non-primary residences may require a more complex Lodging Facility license [12].
  3. Failing to renew on time. There is no grace period. Late fees apply immediately after your Denver rental license expires, whether it's an annual STR or 4-year RRP license. Mark your renewal date and start the process early.
  4. Using an unqualified inspector. The RRP inspection must be completed by a qualified third-party professional using the city's official checklist. Skipping this requirement will cause your application to be rejected.
  5. Forgetting advertisement updates. You must display your license number in all rental advertisements. This is a requirement for both RRP and STR licenses, and failure to comply is a direct violation [11].
  6. Overlooking state disclosures. The Denver rental license is separate from state mandates. For example, Colorado requires radon testing and disclosure for most transactions, and federal law requires lead-based paint disclosures for older homes.

Partnering with a service that understands these nuances, like LandlordFriend's Denver licensing assistance, helps you sidestep these pitfalls efficiently.
