Unincorporated Gallatin County does not have a centralized short-term rental permit; however, most rentals fall under the state definition of a 'Tourist Home.' Hosts must comply with state-level licensing through the Montana DPHHS and adhere to specific zoning district land-use regulations which vary by neighborhood.
To host an Airbnb in unincorporated Gallatin County, you don't need a specific county-wide permit, but you MUST follow state laws. This means getting a 'Tourist Home' license from the Montana Department of Health and Human Services (DPHHS) and registering for state lodging taxes. Crucially, you must check your specific zoning district—some areas like Big Sky have very strict rules and additional 'Resort Taxes,' while other rural areas may have almost no restrictions at all.
