Longmont Short Term Rental Regulation: A Guide For Airbnb Hosts

Do you own a place in Longmont and you're weighing whether to put it on Airbnb or Vrbo? Well, the good news is that Longmont does allow short-term rentals, and the city has a clear, published process for licensing one. The catch, and it's a real one, is who gets to use that process: Longmont's license is open to residents only, so if you don't live in the home you're trying to rent, the door closes before you even get to the fee schedule.

That residency rule is the single fact that decides whether the rest of this guide even applies to you. Longmont sits mostly in Boulder County, with a slice reaching into Weld County, and the city runs its own short-term rental system independent of either county. Everything below, the license, the taxes, the zoning caps, comes straight from Longmont's own pages and forms, checked in July 2026.

So let's walk through what it takes to do this properly: who qualifies, the tax layers that stack on top, how hard the city enforces its own rules, and who to call when you get stuck on something specific to your address. BNBCalc is worth running the property through first, since a Longmont number only means something once you know whether you're even eligible to operate.

What are short term rental (Airbnb, VRBO) regulations in Longmont,Colorado?

Eligibility is where Longmont's rules diverge hardest from most Colorado cities. The city's own page defines a short-term rental as a rental for fewer than 30 days of an entire dwelling or of individual rooms in an owner-occupied dwelling, the kind of thing you'd list on Airbnb or Vrbo. Nothing unusual there.

What is unusual: only a City of Longmont resident can hold the license, and that resident needs at least 50% ownership of the dwelling, or has to be a representative of someone who does. A resident who qualifies can operate a maximum of one investment dwelling as a short-term rental. Buy a second Longmont property purely to run it as an Airbnb, and the city won't license it. Full stop.

Two occupancy rules follow from that same page. Rent the entire dwelling and it goes to one group at a time, no splitting a house into simultaneous separate bookings. Rent individual rooms instead, and the owner, agent, or property manager has to reside in the home and be present while guests are there, which rules out the classic "rent every bedroom separately while I'm elsewhere" model.

Zoning adds a second layer on top of eligibility. Short-term rentals are allowed in every zoning district except Non-residential Primary Employment (N-PE) and Public (N-PF), which covers most of the city. In the Residential Rural (R-RU) and Residential Single Family (R-SF) zones specifically, though, only one short-term rental can operate on each side of the street per block without conditional use approval.

A second one on the same block-side isn't banned outright. It needs a pre-application meeting with staff, a neighborhood meeting before you even submit, and a public hearing in front of the Planning and Zoning Commission, which runs $500 plus a site plan fee as of the city's 2026 fee schedule. That decision can be appealed to City Council if it goes against you.

Colorado itself stays out of the way here. No statewide short-term rental law exists. The state legislature's own research staff put it plainly: "there are no statewide regulations regarding STRs." Longmont is a home-rule city, so its authority to set residency rules, zoning caps and fees comes from its own charter rather than from any state grant. Our Colorado statewide guide covers that preemption picture in full if you want the bigger context.

Starting a Short Term Rental Business in Longmont

Unfortunately for most people reading this, the answer to "can I build a portfolio here" is no. Longmont's residency requirement plus the one-investment-dwelling cap rules out the classic out-of-state investor model entirely, and no LLC structure or property manager gets around it, because the license has to be held by an actual resident-owner. If you don't live in Longmont, or you already own five rentals across the Front Range, this city isn't where that plan works.

What is left is genuinely a resident's side business rather than a scalable portfolio. You live in Longmont, you own the home (or at least half of it), and you either rent the whole place while you're away or rent rooms while you're there. Because the cap is one investment dwelling per resident, a Longmont host is choosing between running their own home as an occasional short-term rental or running a single separate property as a dedicated one. Not both, and not three or four.

Assuming your situation clears that bar, there's still the property itself to qualify. It has to sit in an eligible zone, and if it's in R-RU or R-SF, you'll want to check whether another short-term rental already operates on your side of the block before you assume conditional use approval isn't in your future. It's worth getting that answer before you invest in furnishing anything, since the conditional use process adds a public hearing and a real fee on top of the standard license.

If you're comparing Longmont against a nearby market where the whole unit could legally go to any owner, not only a resident, the Loveland guide and the Greeley guide are useful next reads. Both sit close by in Northern Colorado and neither carries Longmont's residency gate.

Short Term Rental Licensing Requirement in Longmont

So assuming you've confirmed you qualify, here's what the license itself involves. Longmont requires two separate licenses before you can legally take a booking: a short-term rental license and a sales and use tax license, and you need the tax license first, since the STR application won't go through without it.

Both run through the city's Accela Citizen Access portal. You register an account, apply for the sales and use tax license, then apply for the short-term rental license itself, all through the same online portal. In-person applications work too, at the Development Services Center at 385 Kimbark Street. According to the city's own step-by-step guide for the portal, the application asks for four contact roles (Applicant, Contact, Owner, and an optional Manager if a company runs the property for you), plus details on where each bedroom sits in the home.

The fees are modest next to what some Colorado resort towns charge. The short-term rental license itself costs $100, and each annual renewal costs another $100. The separate sales and use tax license adds a one-time $25 processing fee. Licenses aren't permanent, mind you: they run on an annual cycle, and you renew online or in person every year to keep operating legally.

Most of the city's safety expectations are self-certified rather than inspected up front. The items the city expects are ordinary enough. A smoke detector belongs in every bedroom and hallway, plus a carbon monoxide detector within 15 feet of any bedroom where there's an attached garage or a fuel-fired appliance. Egress windows need to meet code dimensions, guests need a working fire extinguisher they can actually reach, the electrical panel has to stay accessible, and every stay needs an evacuation route map.

The city does reserve the right to inspect before it issues a license, or at renewal, if staff decide it's warranted. So treat the self-certification as a real representation, not a formality.

Operate without either license and you're looking at a genuine penalty, not a slap on the wrist. The city calls it a violation of the Longmont Municipal Code, carrying fines of up to $500 per day and/or a summons to court. It's a per-day figure. It accrues.

Required Documents for Longmont Short Term Rentals

Since that $100 still doesn't buy you a lot of paperwork, at least the documents themselves are refreshingly light. Going through the city's own portal walkthrough for the application, the only document you have to upload is a fire escape plan for the property. Everything else on the application is information you type in directly rather than a file you attach: your identity as applicant, the owner's information, a manager if you use one, and a description of each bedroom's location in the home.

Beyond that single attachment, remember what you're assembling before you apply: proof you meet the residency and ownership test, since the license depends on it. The city's page states the ownership bar plainly. Only someone with at least 50% ownership of the dwelling, or a representative of that person, can apply. Keep records of your residency and ownership on hand before you start the online application, because the process assumes you can already answer those questions, not figure them out mid-form.

Do check your zoning district before you apply, too, especially if you're in R-RU or R-SF. Confirming whether another short-term rental already operates on your side of the street can save you from submitting a standard license application that gets bounced into the conditional use track, which adds a neighborhood meeting and a public hearing you didn't plan for.

Longmont Short Term Rental Taxes

Assuming you get through licensing and are able to start hosting, there's still tax to deal with, and Longmont stacks more layers than most people expect from a city this size. Because Longmont is a home-rule city that collects its own sales tax rather than routing it through the state, the math looks a little different than it would in a smaller Colorado town.

Two of the layers belong to the city itself. Longmont charges its own 3.53% sales tax, collected directly by the city rather than the Colorado Department of Revenue, since Longmont self-administers as a home-rule municipality. On top of that sits a separate 2.00% lodger's tax, which the city defines as applying to "the providing of rooms or accommodations... for short term rental (a period of less than 30 consecutive days)," charged on the full asking price including any cleaning fee.

The two are filed separately. The city's own guidance is explicit that you should never combine the sales tax return with the lodger's tax return. Both are due monthly, on the 20th of the following month, filed through longmont.munirevs.com.

State and regional layers stack underneath those two city taxes. The state's own 2.90% sales tax applies statewide. Longmont's own tax page adds an RTD tax of 1.00%, a Cultural District tax of 0.10%, and a Boulder County sales tax of 1.335% on top of that, for a combined citywide sales tax rate of 8.865% as of July 2026. That's before the separate 2% lodger's tax stacks on top.

Charge	Rate	Collected by
Longmont sales tax	3.53%	City of Longmont (self-collected)
Longmont lodger's tax	2.00%	City of Longmont
Colorado state sales tax	2.90%	Colorado Dept. of Revenue
RTD tax	1.00%	State-administered
Cultural District tax	0.10%	State-administered
Boulder County sales tax	1.335%	State-administered

Platforms carry some of that weight for you, at least the two city layers. Airbnb's own Colorado occupancy tax page names Longmont specifically and states it collects both the 3.53% sales tax and the 2.00% lodger's tax automatically on any reservation of 29 nights or shorter.

Going through Colorado's marketplace-facilitator rules, from what I can tell, the state sales tax and the state-administered RTD, Cultural District and county pieces should come through the platform too, under the mechanism the Colorado sales tax guide describes. Airbnb's Longmont-specific listing just doesn't spell that part out line by line, so keep an eye on your own statements rather than assuming.

Here's the part that trips people up: collection by the platform doesn't erase your own city license obligation. Longmont's short-term rental application requires you to hold a sales and use tax license regardless of whether Airbnb or Vrbo already collects the tax on your behalf, since that's a city licensing rule, not a state exemption.

Vrbo, for what it's worth, only says it collects tax "in required jurisdictions" without naming Colorado specifically. Don't assume Vrbo handles Longmont's layers the same way Airbnb does. And your rental income itself is ordinary taxable income at the federal and state level on top of all of this, same as any other business revenue.

Longmont wide Short Term Rental Rules

Every tax detail above assumes you're already operating inside the rules that let you run a short-term rental in the first place, so it's worth pulling those together in one place. Longmont's core rules boil down to five things that apply everywhere in the city, regardless of which zone your home sits in.

• Residency and ownership. Only a City of Longmont resident with at least 50% ownership of the dwelling, or their representative, can hold a license.
• One investment dwelling per resident. A qualifying resident can license their own home plus, at most, one additional investment property, never more.
• One group at a time. Renting the whole dwelling means a single booking party, not multiple simultaneous groups under one roof.
• Presence for room rentals. Renting individual rooms only works if the owner, agent, or property manager is actually present in the home while guests stay.
• Annual renewal. The license runs one year at a time and has to be renewed, online or in person, to stay current.

Zoning sits on top of those five as its own layer, since eligibility doesn't automatically mean a given address qualifies. Remember that R-RU and R-SF zones cap the market at one short-term rental per side of the street per block before conditional use approval kicks in, while N-PE and N-PF zones don't allow short-term rentals at all. Everywhere else in the city is open, assuming you clear the residency and ownership test first.

Does Longmont strictly enforce STR rules?" Is Longmont Airbnb friendly?

Given that mix of a residency gate, a one-property cap, and a real per-day fine, it's fair to ask whether Longmont actually polices any of it or merely publishes the rules and hopes. The honest answer is that Longmont enforces through a mix of self-certification and reserved authority rather than routine inspection of every listing.

The city lets applicants self-certify that a home meets the basic safety criteria, but it explicitly reserves the right to inspect before issuing a license or at renewal if staff decide it's needed. That's backed by a real per-day penalty for anyone who skips the license altogether.

Going through the city's own list of active short-term rental licenses, dated November 2024, I count roughly 110 licensed addresses spread across town, with record IDs running from 2019 through 2024, which tells you licensing has been steady rather than a one-time rush. I couldn't find a more recent public count as of my last check in July 2026, so treat that figure as a snapshot rather than today's exact number, though it does show the system has been running continuously since it started.

Is Longmont Airbnb friendly, then? It leans practical rather than hostile, but the residency requirement does more to shape the market than any fine ever could. A city that limits its own investor pool to people who already live there and already own the property isn't trying to eliminate short-term rentals. It's trying to keep the ones that exist tied to actual Longmont residents rather than absentee owners running a portfolio from out of state.

If you're a Longmont resident who qualifies, the rules read as workable: a modest fee, an annual renewal, and mostly self-certified safety items. If you're not, none of that friendliness matters, because you can't get in the door.

How to Start a Short Term Rental Business in Longmont

Assuming you've confirmed you're eligible and are still ready to move forward, the order below matters, because the early steps decide whether the later ones are worth your time at all.

1. Confirm residency and ownership first. You need to be a City of Longmont resident with at least 50% ownership of the dwelling, or acting as a representative of that owner, before anything else matters.
2. Check your zoning district. Confirm your address isn't in N-PE or N-PF, and if you're in R-RU or R-SF, find out whether another short-term rental already operates on your side of the block.
3. Register on Accela Citizen Access. Create your account at the city's online portal before you apply for anything.
4. Apply for the sales and use tax license first. This has to exist before the short-term rental application will go through, and it carries a $25 one-time fee.
5. Prepare your fire escape plan. It's the one document you upload with the application, so have it ready ahead of time.
6. Apply for the short-term rental license. Pay the $100 fee, fill in the contact roles and bedroom details, and submit through the portal or in person at 385 Kimbark Street.
7. Install and self-certify the required safety items. Smoke detectors in every bedroom and hallway, carbon monoxide detectors where applicable, code-compliant egress windows, a working fire extinguisher, an accessible electrical panel, and a guest evacuation route map.
8. Set up tax filing. Register with longmont.munirevs.com for monthly sales tax and lodger's tax returns, filed separately, and check what your booking platform actually collects on your behalf.
9. Diarize your renewal date. The license runs one year, so renew online or in person at the Development Services Center before it lapses.

Who to contact in Longmont about Short Term Rental Regulations and Zoning?

Whichever step trips you up, Longmont splits its short-term rental questions across two city offices, and knowing which one owns your question saves a call transfer.

Licensing, zoning and code enforcement

The Development Services Center, part of Planning and Development Services, handles the short-term rental license itself, zoning questions, conditional use applications, and code enforcement.

• Address: 385 Kimbark Street, Longmont, CO 80501
• Phone: (303) 651-8695
• Email: [email protected]
• Hours: Monday through Friday, 8 a.m. to 5 p.m.

Sales, use and lodger's tax

The Sales Tax Division of Longmont's Finance Department handles the sales and use tax license, the lodger's tax, and monthly filing questions.

• Address: 350 Kimbark Street, Longmont, CO 80501
• Phone: (303) 651-8672
• Email: [email protected]
• Hours: Monday through Friday, 8 a.m. to 5 p.m.

For anything specific to state sales tax registration or Colorado's marketplace-facilitator rules rather than Longmont's own license, the Colorado Department of Revenue's sales tax guide is the right starting point, since that piece sits outside city hall entirely.

What do Airbnb hosts in Longmont on Reddit and Bigger Pockets think about local regulations?

Public discussion specific to Longmont's rules turns out to be thinner than you'd expect for a city this size, and the residency requirement is probably why. Most of the investors who populate BiggerPockets threads are looking for a market they can operate in from anywhere, and Longmont isn't that market, so it doesn't generate the volume of chatter that a wide-open city like Loveland or Greeley does.

What discussion does exist backs up what this guide already found directly. On a BiggerPockets thread about STR and mid-term rental strategy in Northern Colorado, a Longmont-based real estate agent running his own short-term rental in the city summed it up: regulations "change drastically from city to city" across the region, and he knows other investors running the same model nearby.

That tracks. Longmont's rules aren't unusually strict on paper, they're unusually narrow in who qualifies, which is a different kind of restriction than a fee or an inspection.

I didn't find a live, substantive Reddit thread specific to Longmont's short-term rental ordinance that I could read and verify directly, so I'm not going to characterize sentiment there. What I can say, having gone through the city's own numbers, is that the roughly 110 licenses active as of late 2024 suggest a small but steady population of resident-hosts rather than either a rush or a collapse.

If you're a Longmont resident weighing whether the math works, running the specific address through BNBCalc and comparing it against a nearby market like the Fort Collins area is a reasonable way to see whether the numbers hold up once the license and tax layers are factored in.

Frequently Asked Questions

Can you legally run an Airbnb in Longmont, Colorado in 2026?

Yes, but only if you're a City of Longmont resident with at least 50% ownership of the dwelling, or acting for someone who is. Non-residents cannot get a short-term rental license in Longmont at all. Eligible residents can license their own home plus at most one additional investment property, need both a $100 short-term rental license and a sales and use tax license, and must renew the license every year to keep operating legally.

How much does a Longmont short-term rental license cost?

The short-term rental license itself costs $100, plus another $100 for each annual renewal. A separate sales and use tax license, required before the rental license will be approved, adds a one-time $25 processing fee. Total upfront cost for a first-time applicant runs about $125, not counting any conditional use fee if a second license is needed on the same block-side in an R-RU or R-SF zone.

What taxes apply to a short-term rental in Longmont?

Two city taxes apply directly: a 3.53% sales tax and a separate 2.00% lodger's tax, both self-collected by the City of Longmont and filed monthly. On top of those sit Colorado's 2.90% state sales tax, a 1.00% RTD tax, a 0.10% Cultural District tax, and Boulder County's 1.335% sales tax, for a combined sales tax rate of 8.865% before the lodger's tax. Airbnb collects the city's two taxes automatically; always check what your specific platform actually remits.

Can an out-of-state investor buy a Longmont property and run it as an Airbnb?

No. Longmont restricts short-term rental licenses to city residents who hold at least 50% ownership of the dwelling, so an absentee owner living outside Longmont cannot obtain a license regardless of how the property is titled or managed. This is a residency-based eligibility rule, not a fee or a cap that can be worked around with an LLC or a local property manager.

What happens if you run an unlicensed short-term rental in Longmont?

Operating without a short-term rental license and a sales and use tax license is a violation of the Longmont Municipal Code, carrying fines of up to $500 per day and the possibility of a summons to court. Because the fine is calculated per day, an unlicensed listing left running accumulates penalties the longer it stays active, rather than facing a single flat fine.
