Permit Requirements

The City of Longmont requires every short term rental (rental of an entire dwelling or individual rooms for fewer than 30 consecutive days) to hold both a Short Term Rental (STR) license and a separate Sales and Use Tax license before advertising or accepting bookings. Only City of Longmont residents are eligible, only someone with at least 50% ownership of the dwelling (or their representative) may apply, and a Longmont resident may operate a maximum of one investment dwelling as an STR in addition to their primary residence. The STR license costs $100 to apply and $100 to renew annually; the Sales and Use Tax license carries a one-time $25 processing fee. Applications are filed online through the Accela Citizen Access (ACA) portal or in person at the Development Services Center, 385 Kimbark Street. Operating an STR without a current license is enforceable at up to $500 per day plus a possible summons.

Noise Rules

Longmont does not codify short-term-rental-specific quiet hours; STR guests are subject to the same general noise ordinance as every other resident, located in Longmont Municipal Code Title 10, Chapter 10.20 (Offenses Against the Public Peace). The ordinance makes it unlawful to make noise audible at a distance of at least 25 feet from the source between 10:00 p.m. and 7:00 a.m. unless the noise is contained entirely within the confines of private property the person has a right to occupy. Daytime noise is also regulated against an 'A'-weighted sound-pressure standard. Repeat noise violations originating from a licensed STR are reported to Code Enforcement and may be considered in license-renewal review.

Taxes & Fees

Short-term rentals in Longmont collect a stack of state, regional, county, and city sales/lodging taxes plus a separate City of Longmont Lodger's Excise Tax. The City's lodger tax rate is 2.00% on the full asking price (including cleaning and other fees) for any rental of less than 30 consecutive days. City of Longmont sales tax of 3.53% also applies, on top of the 2.90% Colorado state sales tax, 1.00% RTD (Regional Transportation District) tax, 0.10% Scientific and Cultural Facilities District tax, and Boulder County's 1.335% sales tax, for a combined approximate rate of 10.865% (8.865% general sales tax + 2% lodger excise) on each STR stay. STR operators must hold a City Sales and Use Tax license and file Lodger tax returns monthly through longmont.munirevs.com.

Parking Rules

Longmont's Short Term Rental program does not impose an STR-specific off-street parking ratio beyond the parking minimums that already apply to the dwelling under the Land Development Code (LMC Title 15). STR guests must comply with the citywide on-street parking, time-limit, and overnight-parking rules in LMC Title 11 (Traffic) the same as any other resident or visitor. STR operators are responsible for disclosing on-site parking availability to guests, accommodating guest vehicles within the property's existing off-street capacity, and ensuring guest parking does not block driveways, fire hydrants, sidewalks, or violate any posted neighborhood restrictions.

No STR-Specific Off-Street Parking Mandate; Parking Governed by LMC Title 11 (Traffic) and Title 15 Land Development Code

Occupancy Limits

The Longmont Short Term Rental program limits the maximum number of guests in an STR to two persons per legal bedroom plus two additional occupants. A three-bedroom STR is therefore capped at eight guests, a four-bedroom at ten, and so on. Only rooms originally constructed and code-conforming as bedrooms count toward the count, and any dwelling with more than five bedrooms rented for short-term rentals must be equipped with an approved fire suppression (sprinkler) system. The whole dwelling can only be rented to one group at a time; the occupancy cap is not a per-room figure.

Insurance Requirements

Longmont requires every short-term rental to be covered by liability insurance with minimum limits of $1,000,000. The coverage may take the form of property liability insurance, commercial liability insurance, or an endorsement of the operator's homeowner's policy specifically covering short-term rental activity. Standard homeowner's policies usually exclude business activity, so most operators must add an endorsement or obtain a separate commercial STR policy. Proof of qualifying coverage is part of the STR license application and renewal process.

Night Caps

Longmont does not impose a fixed annual cap on the number of rental nights a licensed short-term rental may host. There is no '90-day,' '120-day,' or '180-day' booking limit codified for hosted or unhosted STRs. Instead, the city controls STR scale through (1) a one-investment-dwelling-per-resident cap, (2) a density rule in the Residential Rural (R-RU) and Residential Single Family (R-SF) zones limiting STRs to one per street segment of a block unless conditional use approval is granted, and (3) an annual license renewal process that evaluates ongoing compliance and nuisance history. A licensed STR may book up to 365 nights per year as long as it complies with occupancy, insurance, and tax obligations.

No Annual Night Cap on Longmont STRs; Density Capped Per R-RU/R-SF Street Segment, No Per-Booking Calendar Limit

Host Presence Rule

Longmont allows two STR configurations. Whole-dwelling STRs may be operated unhosted by a Longmont resident owner (the resident may rent the entire dwelling to one group at a time without being present), subject to all other STR rules. Room-by-room STRs - renting individual rooms within an owner-occupied dwelling - are allowed only when the owner, agent, or property manager resides and is present at the dwelling during the rental period. There is no across-the-board owner-on-site requirement for every STR night, but room rentals categorically require hosted operation.

Primary-Residence-Only Rule

Longmont's STR program restricts licenses to City of Longmont residents only. A resident may operate an STR in their primary residence and may also hold one additional STR license on a second (investment) dwelling they own within Longmont. Out-of-city owners, out-of-state investors, and corporate or LLC owners whose principal operator is not a Longmont resident are categorically ineligible. Each resident is capped at one investment-dwelling STR, and only a person with at least 50% ownership of the dwelling (or their authorized representative) may apply. ADUs generally cannot be used as STRs, removing another common absentee-investor vehicle.
