Airbnb Rules Montana: Laws, Regulations, and Compliance Guide

Montana Airbnb Compliance Checklist

• ☐ Confirm Local Zoning Permits STR Use

  Contact the city or county planning department to verify that the property's zoning classification allows short-term rentals. Missoula, Bozeman, and Whitefish each maintain separate zoning codes; a property in a residential zone in one city may be prohibited outright in another.

• ☐ Obtain a Local STR Permit or Business License

  Apply through the applicable city or county office before listing. Bozeman requires a Short-Term Rental Certificate under its municipal code; Whitefish requires an annual STR license with a fee set by the City of Whitefish Finance Department.

• ☐ Register for a Montana Business License

  File with the Montana Secretary of State if operating as an LLC or corporation. Sole proprietors must still register for state tax purposes with the Montana Department of Revenue.

• ☐ Register for Montana Lodging Facility Use Tax Apply with the Montana Department of Revenue to collect and remit the 4% Lodging Facility Use Tax, which applies to all rentals under 30 consecutive days.

• ☐ Verify HOA or Covenants Restrictions Review the property's CC&Rs and HOA governing documents. HOA prohibitions on STRs are enforceable independently of any municipal permit issued.

• ☐ Install Required Safety Equipment

  • Working smoke detectors in every sleeping room and hallway, per Montana Code Annotated § 50-60-101.

  • Carbon monoxide detectors are required where gas appliances or attached garages are present.

  • A fire extinguisher accessible on each floor level.

• ☐ Post Required Disclosures Inside the Property: Display the local permit or license number, emergency contact information, and maximum occupancy limit. Several Montana municipalities require this posting as a condition of license renewal.

• ☐ Confirm Maximum Occupancy Compliance: Cross-reference local ordinance occupancy limits against the property's bedroom count and square footage. Bozeman's STR rules set occupancy caps that can be lower than what platforms allow by default.

• ☐ Configure the Platform Listing to Reflect Local Limits: Set guest count, minimum night stays, and any locally required quiet hours directly in the listing settings. A permit number must appear in the listing description where the municipality requires it.

• ☐ Set Up Tax Remittance or Confirm Platform Collection: Verify whether Airbnb or Vrbo collects Montana's 4% Lodging Facility Use Tax on the host's behalf for the specific jurisdiction. Where the platform does not collect local resort taxes (as in Big Sky Resort Area District), hosts must remit those separately.

• ☐ Renew Annually and Monitor Ordinance Changes. Most Montana local STR licenses require annual renewal. Bozeman and Missoula have amended their STR

1. Regulatory Overview

Navigating Montana's short-term rental rules isn't simple. It's a bureaucratic maze. The state operates on three distinct compliance layers: state-level business registration, powerful county zoning authority, and specific municipal ordinances where they exist.

There's no single statewide licensing statute, so hosts must satisfy each layer independently, often discovering that local rules for a short-term rental far exceed anything the state requires.

At the state level, the primary instruments are the Montana Lodging Facility Use Tax Act (Montana Code Annotated § 15-65-101 et seq.) and the Montana Accommodations Tax statute (MCA § 15-68-101 et seq.), both of which apply to any rental of a dwelling unit for compensation.

Neither statute creates a statewide registration requirement for STR operators, but both impose collection and remittance obligations that attach automatically once a property is rented.

Montana law defines a short-term rental as any residential dwelling unit rented for periods of fewer than 30 consecutive days. Rentals of 30 days or longer fall outside the lodging tax framework and are treated as residential tenancies under MCA Title 70.

Enforcement authority is fragmented by design. The Montana Department of Revenue (DOR) administers state tax compliance. Local zoning enforcement sits with individual county planning departments or, in incorporated cities, with the relevant municipal code enforcement office.

No single state agency holds the equivalent of a centralized STR enforcement mandate.

2. Airbnb License Requirements in Montana: Is a Permit Required?

Montana has no statewide short-term rental registration program. There is no state registry, no state-issued STR permit, and no primary-residence threshold imposed at the state level.

Hosts operating under Airbnb rules in Montana must look to local municipal codes and county ordinances to determine whether a permit applies to their property.

Local Business License Requirements

Several Montana municipalities require a general business license that covers short-term rental activity, even where no dedicated STR permit exists. Requirements vary significantly by jurisdiction.

• Bozeman: STR operators must obtain a Short-Term Rental License through the City of Bozeman Community Development Department. The city distinguishes between owner-occupied and non-owner-occupied rentals, with separate permit tiers for each.

• Whitefish: A City of Whitefish business license is required for all rental activity. The city also enforces zoning restrictions that limit STR use in certain residential districts.

• Missoula: Hosts must hold a valid business license issued by the City of Missoula. As of January 1, 2024, the city requires STR operators to register with the Missoula City-County Health Department for fire and safety inspections.

No platforms are currently bound by a Montana state-level data-sharing mandate. Airbnb regulation in Montana at the local level does not yet include platform compliance obligations comparable to those in New York or Denver.

County-Level Permits in Unincorporated Areas

Properties outside city limits fall under county jurisdiction. Gallatin County, Flathead County, and Lake County each maintain their own conditional-use permit processes for STR activity in unincorporated zones. Fees and documentation requirements differ by county and are not standardized across the state.

Hosts should contact the relevant county planning department directly to confirm current permit requirements before listing.

3. Safety, Insurance, and Property Standards Hosts Should Review

Montana does not maintain a formal building classification system for short-term rentals. There is no state-level prohibited buildings list, no Class A or Class B dwelling distinction equivalent to New York's Multiple Dwelling Law, and no statewide registry of ineligible property types.

Property eligibility is governed by three sources: local zoning ordinances, HOA covenants and bylaws, and any applicable condo board rules.

What Governs Property Eligibility

Don't assume your property is eligible. A home zoned residential in Bozeman, where the city caps its coveted "Type 3" short-term rental licenses, faces intense restrictions that simply don't exist for a rural cabin in Flathead County. And then there are the HOAs.

Their documents frequently contain strict rental frequency limits, like a 30-day minimum stay, or outright prohibitions that can kill your STR dream before it even starts, no matter what the city allows.

• Zoning Ordinances: Municipal and county zoning codes define where STRs are permitted, often distinguishing owner-occupied from non-owner-occupied rentals.

• HOA Covenants: Private deed restrictions can prohibit rentals under 30 days regardless of local licensing status.

• Condo Board Rules: Boards may restrict or ban STRs through governing documents independent of city ordinances.

State fire and safety standards under the Montana Fire Prevention and Investigation Act (Title 50, Chapter 3, MCA) apply to all occupied dwellings. Local building departments enforce occupancy and habitability requirements.

Hosts operating without confirming zoning compliance face permit denial and potential fines set by individual municipalities.

4. Operational Requirements and Restrictions

Guest Limits

Montana has no statewide statute setting a maximum guest count for short-term rentals. Binding limits come from two sources: local municipal codes and individual property permits.

Missoula's short-term rental ordinance, effective January 1, 2022, caps occupancy at two guests per bedroom plus two additional guests, with an absolute ceiling of ten guests per dwelling unit regardless of bedroom count.

Billings and Bozeman both tie maximum occupancy to the sleeping capacity declared in the host's permit application; exceeding that number constitutes a permit violation subject to revocation.

• Missoula occupancy formula: (Number of bedrooms × 2) + 2, not to exceed 10 total guests.

• Bozeman and Billings: Occupancy is fixed at the figure submitted during the permit or license application. Changes require a permit amendment.

• Unincorporated areas: No county-level occupancy rule applies in most Montana counties; HOA covenants and deed restrictions govern instead.

Minimum-Stay Thresholds

No statewide minimum-stay requirement exists under Montana law. Whitefish imposes a two-night minimum stay during peak seasons (defined as June 15 through September 15 and December 15 through March 15) under Whitefish City Code Section 11-7-040, effective March 1, 2023.

Outside Whitefish, minimum-stay rules are set by individual HOAs or condominium associations, not municipal code.

Host Presence Requirements

Montana imposes no owner-presence or host-presence requirement at the state level. Missoula distinguishes between owner-occupied and non-owner-occupied STR classifications, with non-owner-occupied permits subject to stricter neighborhood caps, but neither classification mandates the host to be on-site during a guest stay.

Note (SB 245, 2025 session): Senate Bill 245, introduced in the 2025 Montana Legislative Session, proposed a statewide framework that would have prohibited municipalities from enacting owner-presence mandates.

The bill passed the Senate but did not advance to a House floor vote before adjournment. Its status remains inactive as of May 2026.

5. Tax Obligations

State Taxes

Montana imposes two state-level taxes on short-term rental revenue. Both apply to rentals of fewer than 30 consecutive days.

Total Combined State Tax Rate: 8% on gross short-term rental receipts. Montana has no general sales tax, so no additional state sales tax layer applies.

Local Taxes

Montana does not authorize local governments to impose separate local lodging taxes on top of state rates. No city or county lodging surcharge applies to STR revenue statewide.

(Certain resort tax districts are an exception: resort communities such as Big Sky, West Yellowstone, and Whitefish levy a resort tax of up to 3% under MCA § 7-6-1501, applied to goods and services sold within the district boundary, which can include lodging.)

Platform Collection Requirements

Airbnb and Vrbo collect and remit both the 4% Lodging Facility Use Tax and the 4% Lodging Sales Tax directly to the Montana Department of Revenue on behalf of hosts under voluntary collection agreements effective since 2019.

Hosts whose bookings flow entirely through these platforms have no remittance obligation for those two taxes on platform-collected revenue.

Tax Filing Requirements

Hosts who accept bookings outside major platforms, direct bookings, and smaller OTAs without collection agreements must register with the Montana Department of Revenue and file returns independently.

Registration is completed through the Montana TransAction Portal (TAP). Failure to register before collecting rental revenue can result in

6. Safety and Building Code Requirements

Mandatory Safety Equipment

• Smoke Detectors: Required in every sleeping room, outside each sleeping area, and on every level of the dwelling, per the Montana Fire Prevention and Investigation Bureau standards adopted under Montana Code Annotated (MCA) § 50-60-101.

• Carbon Monoxide Detectors: Required in any dwelling with fuel-burning appliances or an attached garage, per MCA § 50-60-101.

• Fire Extinguisher: At minimum one 2A:10B: C rated extinguisher per floor, mounted in a visible, accessible location.

• Emergency Egress: Every sleeping room must have at least one exterior window or door meeting minimum opening dimensions under the International Residential Code (IRC) as adopted by Montana.

Building Compliance

• Occupancy Load: Guest capacity must not exceed the local zoning authority's approved occupancy for the structure.

• Electrical and Plumbing: All systems must meet the Montana Building Codes Bureau's adopted standards under MCA § 50-60-201.

• Stairway and Railing Integrity: Handrails and guardrails must comply with IRC Chapter 3 dimensional requirements.

Montana has not enacted any statewide statute requiring booking platforms to verify host registrations before accepting bookings, block unregistered listings, or submit transaction reports to a state agency.

No equivalent to New York City's Local Law 18 of 2022 or San Francisco's Chapter 41A platform-compliance framework exists at the Montana state level as of May 26, 2026.

Individual municipalities, including Whitefish and Bozeman, have adopted local short-term rental ordinances, but none of those ordinances impose direct compliance obligations on platforms themselves.

Enforcement in those jurisdictions falls on the host, not on Airbnb or Vrbo. Platforms operating in Montana collect and remit applicable lodging taxes under voluntary collection agreements with the Montana Department of Revenue, but those agreements are contractual, not statutory mandates tied to registration verification or booking eligibility.

Hosts should not assume platform-side filtering will catch a missing license or permit. That responsibility sits entirely with the operator.

Montana has no STR-specific advertising prohibition. No state statute and no municipal ordinance make it unlawful to advertise a short-term rental before a booking transaction occurs.

General consumer protection standards under the Montana Consumer Protection Act (Mont. Code Ann. § 30-14-103) apply to all commercial advertising, including STR listings, but those rules govern deceptive trade practices broadly; they are not targeted restrictions on advertising short-term rentals as a category.

Hosts operating under local registration requirements in cities such as Whitefish or Bozeman must display their registration number on active listings, but that obligation attaches to the registration requirement itself, not to a standalone advertising law.

7. Enforcement and Penalties

Who enforces the rules? It's all local. Montana doesn't have a single statewide STR enforcement agency, so all authority sits with individual municipalities and counties.

If a local registration program exists, like the one managed by Missoula's Development Services office, it's that specific department that will be handling any violation complaints directly. There's no state hotline to call.

Civil Penalties

• Operating without registration: Penalties vary by municipality. Whitefish imposes fines up to $500 per day for unregistered operation under its municipal code. Bozeman's short-term rental ordinance allows fines of up to $750 per violation, with each day of continued non-compliance treated as a separate violation.

• Tax non-remittance: Don't skip out on your taxes. Code Ann. § 15-65-121, the Montana Department of Revenue assesses a painful penalty of 1.5% per month on any unpaid lodging facility use tax. That's a hefty 18% per year. The penalty keeps compounding until you've settled the entire balance.

• Zoning violations: Operating an STR in a prohibited zone can trigger municipal code enforcement fines separate from any registration penalty.

Enforcement Mechanisms

• Complaint-driven inspections: Most Montana municipalities rely on neighbor complaints as the primary detection method.

• Platform cross-referencing: Code enforcement staff compare active Airbnb and Vrbo listings against the local registration database to identify unlicensed operators.

• Proactive monitoring: Larger jurisdictions, including Bozeman, conduct periodic audits of listing platforms.

Registration Denial and Revocation

• Grounds for denial or revocation: Outstanding code violations, unpaid municipal fines, false application information, or repeated guest disturbance complaints.

• Appeal body: Appeals are heard by the local Board of Adjustment or the municipal court with jurisdiction over the issuing municipality.

Property Owner Liability

Property owners remain liable for violations even when a co-host or property manager holds day-to-day operational responsibility. Delegation does not transfer legal exposure. Owners should confirm in writing that any co-host is maintaining registration and tax compliance, since the municipal fine attaches to the property address, not the operator of record.

8. Special Considerations

Accessory Dwelling Units (ADUs)

Montana has no statewide prohibition on short-term rental use of ADUs, but local zoning ordinances frequently treat detached guesthouses, garage apartments, and basement units as separate dwelling units subject to their own permit requirements.

In Bozeman, for example, ADUs in residential zones require a separate conditional use permit before any commercial rental activity, including short-term rentals, is lawful. Operating an ADU as a short-term rental without that permit can trigger stop-work orders and fines under Bozeman Municipal Code Section 38.360.040.

• Zoning Overlap: ADU zoning classifications often restrict occupancy to long-term tenants by default; hosts must confirm the unit's classification before listing.

• Owner-Occupancy Requirements: Several Montana municipalities tie ADU rental approval to the owner residing on the same parcel, which disqualifies absentee operators entirely.

• Utility Metering: Separately metered ADUs may face additional commercial utility classifications that affect operating costs.

Homeowners Associations and Condominium Declarations

HOA covenants and condominium declarations are private contracts, not municipal law, but they carry real enforcement weight. Montana courts have upheld HOA injunctions against short-term rental activity where declarations explicitly prohibit commercial use.

Violations can result in daily fines set by the association (commonly $50–$250 per day under standard Montana HOA bylaws), forced removal of listings, and, in persistent cases, liens against the property. Hosts must review CC&Rs before listing, not after receiving a cease-and-desist letter.

• Amendment Risk: HOA boards in high-demand resort areas like Whitefish and Big Sky have amended declarations specifically to ban short-term rentals since 2022.

• Rental Cap Clauses: Some declarations cap the percentage of units that may be rented at any one time, affecting eligibility regardless of individual compliance.

9. Exemptions

Not every rental arrangement in Montana falls under short-term rental registration requirements or local STR ordinances.

• Stays of 30 consecutive days or more: These are considered standard residential tenancies under Montana law and are governed by the Montana Residential Landlord and Tenant Act (Montana Code Annotated Title 70, Chapter 24) rather than STR-specific rules.

• Licensed hotels, motels, and inns: Properties operating under a Montana Department of Revenue lodging facility license follow a separate regulatory regime and are not subject to municipal STR registration frameworks.

• Bed and breakfast establishments: B&Bs licensed as lodging facilities operate under distinct state health and safety codes, separate from platform-based short-term rental restrictions.

• Student housing and dormitories: Institutional housing affiliated with accredited educational institutions is exempt from STR ordinances at both state and local levels.

10. Legislative Developments

Montana has not enacted a statewide short-term rental registration or licensing statute as of May 2026.

The most recent enacted change affecting STR operators at the state level was the lodging facility sales tax clarification under Montana Code Annotated § 15-68-101, which took effect on January 1, 2024, confirming that STR platforms collecting taxes on behalf of hosts satisfy the operator's remittance obligation for state lodging tax purposes.

No pending bills specific to Airbnb rules, Montana, or broader STR licensing reform were active in the 2025 Montana Legislative Session. The legislature meets in odd-numbered years only (Montana Constitution, Article V, Section 6), meaning the next regular session opens in January 2027.

Hosts should monitor the Montana Legislature website for interim committee activity and pre-filed bills ahead of that session, as municipal-level pressure in Bozeman and Whitefish has historically preceded state-level action.
