Is a short-term rental legal in Denver, CO?

Short-term rentals (stays under 30 consecutive days) are legal in Denver only in the host's one primary residence, so dedicated investment/second-home STRs are effectively prohibited. A host must hold a Short-Term Rental business license from the Department of Excise and Licenses ($50 application + $100/year, renewed annually) and a Denver Lodger's Tax ID before applying; only natural persons (not LLCs or other entities) may operate an STR. Hosts may rent a room, the whole home (including while away), or a permitted accessory dwelling unit on the same zone lot while living in the main house — but not a duplex's other unit, a neighboring condo, or the main house while living in the ADU. Guests pay 10.75% Denver Lodger's Tax plus 4% Colorado sales tax (14.75% combined), collected by the platform when the booking is transacted through a merchant-of-record platform. Hosts must carry at least $1,000,000 aggregate liability insurance (or book exclusively through a platform providing equal or greater coverage), keep a functioning smoke detector, CO detector and fire extinguisher, display the license number in every ad, allow only one rental contract at a time, and host no parties, weddings or similar events. Violations bring fines up to $999 per incident plus license suspension or revocation, and booking platforms face a strict-liability civil penalty of $1,000 per violation per day for processing payments for unlicensed Denver STRs.

Rules apply to stays under30 days

Both hosted and unhosted rentals are allowed only in the host's licensed primary residence (DRMC 33-47, 33-53(a); Denver Zoning Code 11.8.10.1.B). 'Primary residence' means the place where the person's habitation is fixed for the license term and is their usual place of return; a person can have only one (DRMC 33-46). How often the unit is rented within the year may be weighed as evidence it is not a primary residence (DRMC 33-53(a)(5)). Operators must be natural persons — corporations, partnerships and LLCs are barred (DZC 11.8.10.1.B). A host living in the primary dwelling may also rent an ADU on the same zone lot, but may not live in the ADU and rent the main house, rent the other side of a duplex, or rent a neighboring condo (city ADU/STR Q&A applying DZC 11.8.10). No city-imposed maximum number of guests per night (DZC 11.8.10.1.H), but simultaneous rental to more than one party under separate contracts is prohibited (11.8.10.1.G). STRs may not be in mobile homes, RVs or travel trailers; no non-resident employees; exterior signage limited to one non-illuminated sign of 100 sq. in.; rental for luncheons, banquets, parties, weddings or fundraisers is not an STR use (DZC 11.12.7.7). Stays of 30+ consecutive days are outside the STR ordinance and Lodger's Tax.

License is non-transferable between persons or locations (DRMC 33-51). License number must be displayed on the face of every advertisement (DRMC 33-49(d)). Premises must have a functioning smoke detector, carbon monoxide detector, and fire extinguisher (DRMC 33-49(a)), plus an on-site brochure with licensee, local responsible party, and emergency contacts and neighborhood info (DRMC 33-50). Licensee must keep records of nights/dates rented for the past year (DRMC 33-55(a)). Application must be completed within 1 year or it is closed.

renewal: Annual; renewable up to 90 days before expiration per city renewal page (FAQ says 60 days); late renewal within 90-day grace period incurs 20% penalty (first 30 days) or 50% penalty (days 31-90); after 90 days a new license is required

Liability insurance (fire, hazard and liability) Denver Department of Excise and Licenses / Licensing & Consumer Protection (Rules Governing Short Term Rental Licenses, effective 4/10/2019)
Operating without fire, hazard and liability insurance within director-set limits is unlawful (DRMC 33-49(e)). Rules require liability coverage of no less than $1,000,000 in the aggregate, OR the licensee may instead conduct every STR transaction through a hosting platform providing equal or greater coverage per rental (Rule 3.2). Host must notify their insurance company that the property is used as an STR and submit an affidavit with the application (Rule 3.1). Lapse in coverage triggers automatic license suspension until reinstated (Rule 3.4).

renewal: Must be maintained in full force for the entire license term

Enforcement

PenaltiesHosts: fines up to $999 per incident for violations such as operating without a license (city STR FAQ, reflecting DRMC general penalty referenced in 1-13(a)), plus license denial, fine, suspension, revocation, or non-renewal for primary-residence violations, insurance non-compliance, zoning violations, or operation adversely affecting neighborhood health/safety/welfare (DRMC 33-53, 33-54; STR Rules Sections 4-5). Insurance lapse causes automatic suspension (Rule 3.4). Operating after license expiration is unlawful (DRMC 33-52(d)). Platforms: civil penalty of $1,000 per violation per day for receiving payment for unlicensed Denver STRs or record-keeping failures, strict liability (DRMC 33-49(f)-(h), enacted by CB20-1229). False application statements are made under penalty of perjury (DRMC 33-48(b)).
Platform liabilitySince CB20-1229 (passed November 2020; city summary states effective February 1, 2021), booking service providers are strictly liable ($1,000/violation/day) for processing payments for unlicensed STRs; platforms must retain 5 years of transaction records (host name, address, dates, price, license number) and the city publishes a list of all licensed STRs (DRMC 33-55). The Director of Excise and Licenses has subpoena power (DRMC 32-26).
NotesDenver pairs licensing with active primary-residence enforcement: the Director may weigh voter registration, tax records, time spent at the property and rental frequency (DRMC 33-53(a)). Per news reports (not independently verified against official records): the city has revoked licenses for primary-residence violations, and in 2019 the Denver DA filed felony 'attempting to influence a public servant' charges against four hosts over primary-residence attestations — those charges were later dismissed.

Pending changes

What we could not verify (8)

  • Current codified text of DRMC Chapter 33, Article III (Secs. 33-46 to 33-57) could not be fetched from library.municode.com (HTTP 403); all code citations were instead verified against the city-posted signed ordinance PDFs (CB20-0240, CB20-1229) and official city summaries — confirm no post-2020 amendments to Article III in the codified DRMC.
  • Whether Denver charges a fee for the Lodger's Tax ID/license registration was not verified; value set to null.
  • Renewal window discrepancy between official pages: city FAQ says renewal may be submitted up to 60 days before expiration; the renewal application page says up to 90 days.
  • Colorado's 4% state sales tax on lodging and platform (marketplace facilitator) collection of the state tax were verified only via Denver's Tax Guide Topic 97, not against a Colorado Department of Revenue or C.R.S. source; collectedByPlatform for the state tax set to null.
  • CB20-1229 effective-date ambiguity: the signed bill text reads 'on and after February 1, 2020' for the platform prohibition, while the city's laws/rules page states it took effect February 1, 2021.
  • Enforcement history items (first license revocation; 2019 felony charges against four hosts, later dismissed) are sourced to news outlets (9News, BusinessDen) and were not verified against official DA or Excise & Licenses records.
  • The exact maximum fine ('up to $999 per incident') comes from the official city FAQ; the underlying DRMC Sec. 1-13(a) general-penalty text was not directly fetched.
  • No 2025-2026 Denver ordinance or rule changes to the STR program were found in official sources or news searches, but absence of change could not be positively proven; a check of Denver City Council records for 2025-2026 amendments to DRMC Ch. 33 Art. III is recommended.
