Arapahoe County, Colorado Short-Term Rental Regulations: A 2026 Guide For Airbnb Hosts

Do you own a place in unincorporated Arapahoe County, Colorado and you're weighing whether to put it on Airbnb or Vrbo? Well, the honest answer is that you probably can, but only if you actually live there, because the rules changed under your feet very recently. For years the county's unincorporated pockets had no short-term rental rules at all, so people bought, furnished and listed whole houses with nobody asking questions. That era ended on June 20, 2026.

That's the date Ordinance 2026-01 took effect, and it carries a catch that reshapes the whole picture: a licensed short-term rental in unincorporated Arapahoe County has to be your primary residence. So the classic investor play, a second home rented whole at nightly rates, is off the table now unless your property was already operating and you claim a legacy exemption before the window shuts. Keep in mind too that this only covers the county's unincorporated land. Aurora, Centennial, Englewood, Littleton, Greenwood Village and the other incorporated cities each write their own rules, and none of what follows applies inside their limits.

So let's walk through what it actually takes to do this properly in 2026: what the county now requires, what a license costs, the primary-residence and legacy rules that decide whether you even qualify, the layers of tax you'll be collecting, how hard any of it gets enforced, and who to call when you get stuck. Everything below comes from Arapahoe County's own ordinance and the state's own tax pages, checked in July 2026, and where a figure is still moving I've said so. Before you spend a dollar furnishing anything, run your address through BNBCalc first, because the primary-residence rule quietly rules a lot of properties out.

What are Short-Term Rental (Airbnb, VRBO) Regulations in Arapahoe County, Colorado?

Since those rules are barely a couple of months old, it helps to see how the layers stack, because two governments regulate the same stay and people mix them up constantly. The county ordinance sits on top of Colorado state law, and each does a different job.

At the county level, Ordinance 2026-01 defines a short-term rental as the rental of a lodging unit for less than 30 days, and it makes operating or even advertising one without a county license unlawful in the unincorporated territory. The Board of County Commissioners adopted it on May 12, 2026 under the authority Colorado gives counties in C.R.S. § 30-15-401(1)(s), and it took effect 30 days after publication. Anything rented for 30 days or longer falls outside it entirely, as do hotels, motels, guest ranches and bed-and-breakfast establishments, which are governed separately.

The scope is where most confusion starts, so be clear on it. This ordinance reaches only unincorporated Arapahoe County, meaning the land that isn't inside a city or town. If your property sits in Aurora, Centennial, Englewood, Littleton, Sheridan, Greenwood Village, Cherry Hills Village or any other municipality, you follow that city's code instead, and the county license does nothing for you.

A quick way to check is your mailing city against your actual jurisdiction, since a Littleton or Aurora postal address doesn't always mean you're inside city limits. When you're not sure, do call the county before you assume either way.

Above the county sits the state, though Colorado deliberately leaves this to local government. The legislature's own nonpartisan research staff says as much, that there are no statewide regulations regarding STRs. So the state hands counties their licensing authority and collects the taxes I'll get to below, which is why the county writes the rules and the state mostly writes the tax bill.

Starting a Short-Term Rental Business in Arapahoe County

Once you understand that the county now licenses these rentals, the first hard question is whether you're even eligible, and for a lot of would-be hosts the answer is no. Unfortunately for anyone hoping to buy a place just to rent it out, there's no investment model here anymore. The ordinance requires that a licensed short-term rental be the primary residence of the licensee, and a person can only have one primary residence. So a second home, a pure rental, or an out-of-state owner's Colorado property simply can't be licensed as a non-legacy short-term rental.

What's left for most people is a hosted or part-time model built around the home you already live in. You can rent a room, or rent the whole house while you're away, as long as that house is genuinely your primary residence and you can prove it with at least two documents. That still leaves real revenue on the table, but it's the revenue of a spare room or an occasional whole-home stay, not a dedicated nightly-rental unit, so model it that way from the start.

There's one door out of the primary-residence trap, and it's closing fast. If your property was already operating as a short-term rental before June 20, 2026, you may qualify for a legacy designation that excuses it from the primary-residence requirement, and depending on the prior use, from the separation and multi-family rules as well. To claim it you have to apply between June 20 and August 23, 2026 and show the unit was marketed and used as a short-term rental within the six months before the county started regulating.

Miss that window and the exemption is gone, because the ordinance says supplemental materials won't be considered after the fact. Legacy status also expires the moment the property changes hands or you fail to renew. So it doesn't transfer to a buyer.

Assuming you don't hold a legacy claim, the county won't even open new non-legacy applications until it has processed the legacy ones, which it expects to be late autumn 2026. And if your property turns out to sit inside a city rather than unincorporated land, your next stop is that city's rules.

Short-Term Rental Licensing Requirements in Arapahoe County

Say your home clears the primary-residence bar and you're ready to apply. The license itself is issued by Arapahoe County Public Works and Development, and it comes with a fee schedule, a fixed term, and a fairly long list of operating conditions attached to it. Here's the money and the calendar first, since those are the parts people ask about most.

Item	Amount / term	Notes
Application review fee	$200	Paid before the county reviews your application, non-refundable
Annual license fee	$350	Paid before the license is issued
License term	1 calendar year from issuance	Personal to you; ends automatically if the home stops being your primary residence
Renewal window	60 to 120 days before expiration	Filing fewer than 60 days out can get you denied

Every fee is non-refundable, whether you're denied, you withdraw, or you stop renting, so make sure you actually qualify before you pay. The license covers one unit only, it isn't transferable, and it's valid solely for the person named on it. When the property sells or a licensed lessee moves out, the license expires on its own.

Beyond the fee, the ordinance loads on requirements that decide whether a given property can be licensed at all. These are the ones that catch people:

• A Local Responsible Agent (LRA). You must name someone who can answer the phone within 15 minutes and be physically at the property within 60 minutes to deal with a guest or neighbor problem. You can name yourself if you meet the standard, but either you or the LRA has to be reachable 24/7 whenever the place is occupied. An answering service or a text bot doesn't count.
• $1 million in liability insurance. You need coverage for property damage and bodily injury of at least $1 million per claim and in the aggregate, held for the whole license term, or you can run every booking through a hosting platform that provides equal or greater coverage per stay.
• A parking plan. At least one off-street space for a studio or one-bedroom, and two spaces for anything with two or more bedrooms.
• The 500-foot separation rule. For detached houses, duplexes and townhomes, the county won't license a new short-term rental within 500 feet of another licensed one, measured property line to property line. It's there to stop rentals clustering on a single block, and legacy properties are exempt from it.
• A hard cap on apartments and condos. Across all of unincorporated Arapahoe County, no more than 100 licenses will be issued in multi-family buildings. Once that's hit, the county runs a waitlist, so if you own a condo, be aware you could be in line behind other applicants.
• Occupancy limits. Overnight occupancy is capped at two people per bedroom plus two more, and only one renting party may occupy the property at a time. A "bedroom" has to be a real one: at least 70 square feet, a seven-foot ceiling, and two ways out.
• Accessory dwelling units are mostly out. You can't license an ADU for short-term rental unless the underlying parcel is nine acres or larger.

One more requirement lands after approval rather than before it. Within 14 days of getting your license, you have to deliver a signed Good Neighbor Notice to every adjoining neighbor and anyone directly across a street or alley, then upload a certification of mailing. It names the property, gives your LRA's contact, and lays out the house rules on noise, parking and the rest, so your neighbors know exactly who to call.

Required Documents for Arapahoe County Short-Term Rentals

Because that $200 review fee doesn't come back, it's worth assembling the paperwork carefully before you submit rather than after. The application runs through the county's Accela customer portal, and the ordinance spells out exactly what has to be in the packet:

• Proof it's your primary residence, at least two documents from the approved set: valid motor-vehicle registration, voter registration, federal or state tax returns or other financial documents, or anything else the Director accepts as evidence of where you actually live.
• Owner authorization, if you're a lessee applying rather than the owner, plus signatures from every owner of record where the property has more than one.
• Your LRA authorization form, naming the agent and granting them authority to manage the rental, make repairs, and respond on your behalf.
• Proof of $1 million liability insurance, or evidence of equivalent platform coverage.
• A parking plan showing the required off-street spaces.
• Life-safety evidence, covering the smoke detectors, carbon monoxide detectors, fire extinguishers, sound structure, working plumbing and labeled electrical panels the ordinance requires.
• Your interior signage and written guest instructions, matching the ordinance's content list.
• The signed Good Neighbor Notice document.
• A signed annual affidavit, sworn under penalty of perjury, certifying the property meets the life-safety standards and that the required signage and instructions will stay posted.

Two details trip applicants up, so remember them. The county does not run an initial inspection; instead you self-certify life-safety compliance through that affidavit, which means the burden of getting it right sits on you, and a later inspection can catch a bad claim. And any lodging unit on a septic (OWTS) system must have passed inspection within the 12 months before you're first licensed, so if you're on a well-and-septic parcel out east, get that scheduled early.

Arapahoe County Short-Term Rental Taxes

Assuming you get through all that and are able to start hosting, there's still tax to deal with, and it's collected by several governments at once. The ordinance itself keeps this short: the licensee or LRA has to collect and remit every applicable local, state and federal tax on the rent, and the real detail lives in the state's rate tables. Because your address is unincorporated, the state administers that whole stack for you.

Charge	Rate	Collected by
Colorado state sales tax	2.9%	Colorado Dept of Revenue
Arapahoe County sales tax	0.25%	Colorado Dept of Revenue
RTD (Regional Transportation District)	1.0%	Colorado Dept of Revenue
SCFD (Scientific and Cultural Facilities District)	0.1%	Colorado Dept of Revenue

So for most of unincorporated Arapahoe County, the part inside the metro transit district, those layers come to a combined 4.25% state-administered rate as of July 2026. The nuance worth watching is RTD: it covers the western, more urban portion of the unincorporated county but stops before the rural east, so a property out toward Deer Trail or Byers sits outside RTD and lands closer to 3.25%. Since the rate genuinely depends on your exact address, do check yours against the Colorado Department of Revenue's own rate lookup rather than assuming the metro figure. On the county lodging tax question, I couldn't confirm from the state's current lodging-tax publication whether Arapahoe adds a separate county lodging levy on top, so treat that as one more line to verify for your address before you set your pricing.

The good news on collection is that the platforms handle a lot of it. Airbnb collects Colorado state sales tax, county lodging tax, local marketing district tax, local sales tax and metropolitan district tax for you where they apply, with the caveat that you stay responsible for anything it doesn't cover. Even so, you generally still need your own Colorado sales tax license from the Department of Revenue, which runs a $16 fee plus a refundable $50 deposit and renews at the end of each odd-numbered year. The one exception is where every single booking runs through a marketplace that collects all the applicable tax for you, which can relieve you of the license and filing entirely. If you take even one direct booking, though, plan on holding the license yourself.

Colorado Wide Short-Term Rental Rules

Those state taxes are the visible half of a wider framework, and it's worth knowing the state layer because it explains why the county rules look the way they do. Colorado doesn't preempt local short-term rental regulation, so every county and city is free to license, cap, zone or ban as it sees fit. That's the legal room Arapahoe County used to write Ordinance 2026-01 in the first place.

The specific authority comes from House Bill 20-1093. It added the subsection of C.R.S. § 30-15-401 that lets a county license and regulate an owner who rents a lodging unit short-term, set the fees and terms, and require a platform to pull a listing once the county reports the local license suspended or revoked. A later bill, HB23-1287, standardized the definitions of "lodging unit," "short-term rental" and "vacation rental service" that the county ordinance now mirrors. Neither one caps fees or restricts what a county can require, which is why Arapahoe was free to add a primary-residence rule and a 500-foot buffer.

On the tax side, one recent change is worth tracking if you own in a county that leans on tourism. HB25-1247, signed in May 2025, raised the ceiling on the voter-approvable county lodging tax from 2% to 6% and broadened what the money can fund. It doesn't automatically change your bill, since any increase still has to go to voters, but it's the mechanism to watch in the next couple of years. For the full state picture, our Colorado statewide guide lays out the registration, tax and platform-collection rules that apply everywhere, and the Jefferson County guide shows how another metro county handles the same authority.

Does Arapahoe County Strictly Enforce STR Rules?

Given how new all of this is, the honest read is that enforcement is just getting started, but the county clearly built the ordinance to have teeth. It set up a dedicated complaint hotline at 720-796-4758 and an online complaint portal from day one, and it contracts with a compliance vendor to field reports, which is the same monitoring model Colorado's tourist towns have used for years to catch unlicensed listings.

The penalties escalate the way these ordinances usually do, and the part that bites is the daily clock. A violation is a civil infraction carrying a fine of $250 for a first offense, $500 for a second, and $1,000 for a third and any after that, plus a small court surcharge. That's not a one-time fine, though. The clock runs daily. Each day a violation continues counts as a separate offense, so an unlicensed rental left running can rack up penalties fast, and the county can skip the usual warning entirely where the problem touches health, safety or a neighbor's quality of life.

Losing the license is the bigger risk. The Director can suspend it for repeated violations, an unavailable LRA, an uncured building or fire code problem, unpaid property tax, or unpaid fees, and can revoke it outright after more than one suspension in a year or a materially false statement on your application. A revocation locks the property out of short-term rental use for at least a year, after which you'd have to start a fresh application and clear the separation rule all over again. Watch out for one more thing: the licensee and the owner are jointly and severally liable, so naming a management company as your LRA doesn't move the responsibility off you. An Authorized Public Inspector can also enter to inspect, and that inspector can be the Director's designee or a Sheriff's deputy. So a listing that quietly breaks the rules isn't as invisible as it might feel.

How to Start a Short-Term Rental Business in Arapahoe County

Knowing how the penalties land, the order you do things in matters, because the early steps tell you whether the later ones are worth the money. Work through it roughly like this:

1. Confirm you're actually in unincorporated Arapahoe County. Check your address against the county's jurisdiction, not just your mailing city. If you're inside a municipality, stop here and follow that city's rules instead.
2. Confirm the home is your primary residence, or that you qualify for a legacy exemption and can apply before the August 23, 2026 deadline. This is the step that decides whether there's a business at all.
3. Line up your Local Responsible Agent. Decide whether you can meet the 15-minute and 60-minute response standard yourself, or whether you need a local manager.
4. Get your $1 million liability coverage in place, or confirm your platform's coverage qualifies.
5. Handle the safety and paperwork items: smoke and CO detectors, fire extinguishers, a parking plan, the interior signage and written guest instructions, and, if you're on septic, a passed OWTS inspection within the last 12 months.
6. Register for your Colorado sales tax license with the Department of Revenue unless every booking will run through a tax-collecting platform.
7. Apply and pay the $200 review fee through the Accela portal, then the $350 license fee once you're approved.
8. Deliver the Good Neighbor Notice to the right neighbors within 14 days of approval, and upload your certification of mailing.
9. Diarize your renewal. The license runs one year, and the renewal window is 60 to 120 days before it expires, so don't forget to file inside it.

What Do Airbnb Hosts in Arapahoe County on Reddit and Bigger Pockets Think about Local Regulations?

Since the office handling all this is the same one hosts have been calling with questions, it's no surprise the local conversation right now is mostly people figuring out where they stand. What follows is my read of the recurring themes rather than any kind of survey, so do weigh it accordingly.

• The primary-residence rule is the shock. The loudest reaction among Colorado investors is that a market which used to be wide open for whole-home rentals suddenly isn't, and the advice on forums like BiggerPockets has shifted toward hosted models or toward counties and cities with looser rules.
• The legacy window is the scramble. Existing operators are focused on documenting their history in time, because the August 2026 deadline is firm and the county won't take late evidence. The people who kept good booking and tax records are in far better shape than those who didn't.
• The LRA standard gets attention. The 15-minute phone and 60-minute on-site response requirement reads as strict to owners who don't live nearby, and it's pushing some toward hiring a local manager, which changes the math on a part-time rental.
• Nobody's arguing the rules don't exist anymore. That debate is over. The conversation now is about who qualifies and how to comply, which is a very different footing from the pre-2026 free-for-all.

Take the last point seriously if you're modeling a purchase. The window for buying a place in unincorporated Arapahoe County just to rent it whole has effectively closed, so any numbers built on that assumption need rethinking. If you're comparing where a hosted rental actually performs across the state, the Colorado market data is the place to sanity-check your revenue before you commit.

Frequently Asked Questions

Can you run an Airbnb in unincorporated Arapahoe County in 2026?

Only if the property is your primary residence, or it qualifies as a legacy rental. Since June 20, 2026, unincorporated Arapahoe County requires a short-term rental license under Ordinance 2026-01, and non-legacy licenses are limited to a host's primary home. A pure investment rental of a second home can't be licensed unless it was already operating and claims a legacy exemption by August 23, 2026.

How much does an Arapahoe County short-term rental license cost?

It's a $200 application review fee plus a $350 annual license fee, and both are non-refundable even if you're denied. The license lasts one calendar year from issuance, and you renew between 60 and 120 days before it expires. On top of the county fees, most hosts also need a Colorado state sales tax license, which costs a $16 fee and a refundable $50 deposit.

What taxes do you collect on an Arapahoe County short-term rental?

For most unincorporated addresses inside the metro transit district, the combined state-administered sales tax is about 4.25%: 2.9% state, 0.25% county, 1.0% RTD and 0.1% SCFD. Rural eastern areas outside RTD run closer to 3.25%. Airbnb collects most of these automatically, but the rate depends on your exact address, so confirm yours with the Colorado Department of Revenue.

Does the Arapahoe County rule apply if I'm in Aurora or Centennial?

No. Ordinance 2026-01 only covers unincorporated Arapahoe County, meaning land that isn't inside a city or town. Aurora, Centennial, Englewood, Littleton, Greenwood Village and the county's other municipalities each set their own short-term rental rules, and the county license doesn't apply there. Check your actual jurisdiction, since a postal city name doesn't always match your legal city.

What happens if you rent without an Arapahoe County license?

Operating or advertising an unlicensed short-term rental is a civil infraction carrying fines of $250 for a first violation, $500 for a second, and $1,000 for a third and beyond, plus a court surcharge. Each day counts as a separate offense, so the fines compound quickly, and the county can act without a warning where health, safety or neighbors are affected.
