Short-term rental rules in Big Sky, MT
Big Sky is unincorporated and split across Gallatin and Madison counties; there is no city government, so STR regulation comes from Gallatin County zoning and the Big Sky Resort Area District's 4% Resort Tax. Only two Gallatin County zoning districts mention STRs (Gallatin Canyon/Big Sky and Hebgen Lake); many Big Sky parcels are unzoned and have no county-level STR restriction at all. Operators must collect the 4% Resort Tax (remitted monthly via MUNIRevs, quarterly if under $1,000/yr) on all stays under 30 days, plus Montana's 8% state lodging taxes (4% Lodging Facility Use Tax + 4% Lodging Sales Tax). A Gallatin County Health Department permit, Montana Public Accommodations License, and $1,000,000 liability insurance are required.

Frequently asked
Are short-term rentals legal in Big Sky, MT?
Big Sky is currently permitted for short-term rentals. Active permits with clear rules and no recent ordinance tightening — stable for new STR investment. For the actual fees, caps, owner-occupancy rules, and city-specific gotchas, sign in.
Do I need a permit to run an Airbnb in Big Sky?
Almost certainly yes — almost every U.S. city now requires a short-term rental permit, vacation rental permit, or transient lodging permit before you can legally list. The specifics for Big Sky (cost, renewal cycle, required documents) are behind sign-in. You can also read the source ordinance directly: https://resorttax.org/collections/.
What happens if I rent without a permit in Big Sky?
Most cities charge per-night fines (a few hundred to a few thousand dollars per violation), escalating to cease-and-desist letters and platform delisting on repeat. Airbnb and Vrbo now share permit-validation feeds with most major cities, so unpermitted listings get blocked at the platform level. Sign in to see the specific penalty schedule for Big Sky.
How current is this data for Big Sky?
This record was verified 1mo ago against the city's published ordinance (.gov or the city's official municipal-code publisher). Cached cities re-verify on a cadence — daily for cities under active legislation, weekly otherwise. Signed-in users can hit Refresh on any city to force a fresh pull. If you're underwriting a deal, always confirm against the city's code-enforcement office before closing.
Can my HOA or condo association ban STRs even if Big Sky allows them?
Yes. City permits authorize you under municipal law, but your HOA, condo association, or co-op board sets contractual rules that override the city for your unit. Many HOAs adopted blanket STR bans between 2018 and 2024 in response to neighbor complaints. Read the CC&Rs, bylaws, and rental addendums before you buy with an STR plan — the city saying yes does not mean your building says yes.
