Vacation rental License Requirements in Denver, CO

While the federal government does not mandate a specific license for vacation rental operation, several federal laws and agencies apply to vacation rental businesses in Denver. The Fair Housing Act (42 U.S.C. § 3601 et seq.) prohibits discrimination in housing, including short-term rentals, based on protected classes. The Americans with Disabilities Act (42 U.S.C. § 12101 et seq.) requires that rental properties be accessible to guests with disabilities when feasible.

EIN requirements under 26 U.S.C. § 401 apply if you operate as a business entity or have employees. The IRS requires reporting of rental income on Schedule E (Form 1040) and may require estimated quarterly tax payments (1040-ES). If your property has a swimming pool or hot tub, the Virginia Graeme Baker Pool and Spa Safety Act (15 U.S.C. § 8001 et seq.) mandates drain safety covers.

Occupational Safety and Health Administration (OSHA) standards may apply if you employ housekeeping staff. The Consumer Product Safety Commission (CPSC) requires that all furnishings and appliances meet federal safety standards. Additionally, if your property was built before 1978, EPA Lead-Based Paint Disclosure rules (40 CFR Part 745) require disclosure of known lead hazards. Travel taxes and platform reporting obligations may trigger filing requirements with the Colorado Department of Revenue and Denver's Department of Finance.

Denver imposes strict local requirements for vacation rental operation. The primary requirement is Short-Term Rental (STR) Zoning Compliance under Denver Zoning Code § 12.4.6. Properties in residential zones may operate as STRs only if the owner occupies the property as a principal residence, or the property is used for limited occasions (e.g., owner absent for work assignment). Commercial zones and hotels-residential districts permit STRs without principal residence restriction.

A Use and Occupancy Permit from Denver CPD is mandatory and requires property inspection by building and fire safety officials. Maximum occupancy limits are set based on bedroom count and egress requirements (typically two occupants per bedroom plus two additional guests). Fire safety devices including NFPA-compliant smoke and carbon monoxide detectors in all sleeping areas and common areas are required.

Denver requires a Short-Term Rental License number displayed on the property listing and all advertising. Hosts must maintain a Guest Log documenting each reservation period and number of occupants (Denver Revised Municipal Code § 27-365). Parking requirements vary by neighborhood; some areas require off-street parking for guests. Property insurance must explicitly cover short-term rental activity and include liability coverage of at least $300,000.

Neighborhoods impose additional restrictions. Capitol Hill, Highland, and Highlands areas have stricter occupancy caps and quiet hours (10 p.m.–7 a.m.). The City and County of Denver enforces a cap on the number of STRs permitted in each council district. Some areas prohibit STRs entirely; verify your specific neighborhood at https://denvergov.org/pocketgov/services or contact CPD at 720-913-1311.

The first-year cost for operating a vacation rental in Denver includes multiple required expenses. The Short-Term Rental License and Use and Occupancy Permit registration fee is $360–$600, depending on the property's occupancy classification and zone. A mandatory building and fire safety inspection, if not already current, may cost $100–$300 if you hire a certified inspector (though CPD provides inspections at minimal cost).

Property insurance is a critical expense. Standard homeowner's insurance does not cover short-term rental activity; you must obtain STR-specific coverage, which typically costs $800–$1,500 annually for a mid-range residential property in Denver (compared to $600–$900 for standard homeowner's insurance). Liability coverage of at least $300,000 is required.

Licensing and administrative costs include the initial application fee ($50–$100) and potential expedited processing fees ($25–$75 if requesting priority review). Some hosts hire a local compliance consultant to navigate zoning verification and documentation requirements; this service costs $200–$500.

Additional first-year costs may include property modifications to meet fire and safety code requirements (smoke detectors, carbon monoxide detectors, fire extinguishers, etc.), estimated at $200–$600. If the property requires accessibility upgrades under ADA guidelines, costs range from $500–$2,000.

Total realistic first-year cost range: $1,710–$3,175. This includes the license fee ($360–$600), insurance ($800–$1,500), inspection and permitting ($100–$300), and safety equipment ($200–$600). Subsequent annual renewal costs drop to approximately $1,160–$2,100 (license renewal plus annual insurance), as one-time setup expenses are not repeated.

Denver's Short-Term Rental License and Use and Occupancy Permit operate on an annual renewal cycle. Licenses expire on December 31st of each year. Renewal deadline is typically 30 days before expiration; applications submitted after January 1st are considered delinquent and may incur late fees of $50–$100. You must renew before operating the property in the following year.

Renewal requires submission of updated proof of homeowner's or rental property insurance covering short-term rental activity, confirmation of continued compliance with zoning requirements, and current property inspection certification if required by CPD (inspections may be requested every 2–3 years, particularly if violations were noted).

Online renewal is available through the Denver Licensing Hub at https://denvergov.org/pocketgov/services. In-person renewal is available at the CPD office, 201 West Colfax Ave, Suite 700, Denver, CO 80202. Renewal fees range from $360–$600 depending on property size and zone. Colorado does not mandate continuing education for vacation rental hosts, though the City of Denver periodically offers optional STR compliance webinars.

If you miss the renewal deadline, your license becomes inactive immediately. Operating an unlicensed rental incurs daily fines of $500–$999. The City may issue a cease-and-desist notice requiring immediate termination of guest bookings. Failure to cure violations within 30 days may result in civil enforcement action and additional penalties.

Operating a vacation rental without a Denver Short-Term Rental License and Use and Occupancy Permit is a violation of Denver Revised Municipal Code § 27-368 and carries substantial penalties. The base penalty is a fine of up to $999 per day of unlicensed operation. For example, a property operated unlicensed for 30 days could incur fines of $29,970.

Violations are treated as civil infractions, and the City pursues enforcement through the Denver Community Planning and Development department's compliance division. Violations are discovered through neighbor complaints, platform monitoring (Airbnb and VRBO provide registration data to the City), and routine property audits. The City coordinates with short-term rental platforms to cross-reference licensed properties against active listings.

When a violation is discovered, the City issues a Notice of Violation and typically provides 30 days for cure (registration and licensing completion). If the property is not brought into compliance within this period, the City issues a Cease and Desist Order requiring immediate cessation of short-term rental activity. Continued operation after a Cease and Desist Order escalates the violation to a misdemeanor, subject to criminal penalties including up to 12 months in jail and fines up to $2,600 (Colorado Revised Statutes § 12-47-901 et seq.).

Civil enforcement remedies include nuisance abatement (the City can padlock the property) and collection of all unpaid fines as a lien against the property. Insurance implications are severe: operating without registration voids coverage under homeowner or rental property policies, leaving the host personally liable for guest injuries or property damage. Additionally, platforms such as Airbnb and VRBO enforce delist policies for unlicensed properties in jurisdictions requiring registration, removing the property from availability.
