Short-term rental rules in Big Sky
Rules depend on the exact city, county and zoning district, and they change. Here’s what the official sources say as of November 2026:
- Gallatin County: if a zoning district’s regulations don’t mention short-term rentals, they aren’t permitted there. In the Gallatin Canyon/Big Sky district they are a permitted use only in listed sub-districts (such as R-MF 3500, R-SF 7500, RC-SF, CC, TCC and R). The County also points owners to a Public Accommodations License from the Gallatin City-County Health Department. Source: Gallatin County: Short-Term Rental FAQs
- Montana’s lodging facility sales and use tax applies to stays under 30 days. Source: Montana DOR: Lodging Facility Sales and Use Tax
- Within the Big Sky Resort Area District (Gallatin and Madison counties), lodging is subject to the District’s resort tax with annual business registration. Source: Big Sky Resort Area District: Resort Tax FAQs
- Madison County side: confirm current zoning rules with Madison County.
Summaries, not legal advice. Confirm current rules with the locality, and any HOA or condo association, before you make an offer.
HOA, condo and insurance considerations
Ski-area condos and cabins: review HOA rental rules, assessments and wildfire coverage.
Many vacation communities have HOA or condo rules that are stricter than the city or county: minimum stays, rental registration, guest limits or outright bans. Ask for the governing documents and rental rules before your due-diligence period ends. Lenders review condo projects too, so share the association’s details early.
How the financing usually works
- Mostly your family’s place, occasional renting: usually a second home. Under Fannie Mae’s occupancy rules it must be a one-unit home under your exclusive control, not primarily operated as a rental, and rental income generally can’t be used to qualify.
- Mostly renters: lenders treat it as an investment property, which is underwritten and priced differently, and documented rental income can sometimes help you qualify.
- Resort or condo rental programs that control your calendar can affect second-home eligibility. Share any management agreement with me early.
- Count the cost of two homes: your current payment plus the new home’s taxes, insurance, HOA dues and any rental-license or inspection costs.

Before you write an offer
- Confirm the jurisdiction (city vs. unincorporated county) and zoning district for the exact parcel.
- Check whether a short-term rental permit, license or registration is available for that address, and any cap or waitlist.
- Get the HOA or condo rental rules in writing.
- Price insurance (including flood or wind where relevant) during due diligence.
- Decide honestly how you’ll use it, so the loan is classified correctly from day one.

Big Sky questions
What taxes apply to a short-term rental in Big Sky, Montana?
Montana’s lodging facility sales and use tax applies to stays under 30 days, and properties inside the Big Sky Resort Area District are also subject to the District’s resort tax with annual business registration.
Can I finance a Big Sky vacation home as a second home and still rent it out sometimes?
Possibly. Under Fannie Mae’s guidelines a second home must be a one-unit home you occupy for part of the year, keep under your exclusive control and don’t primarily operate as a rental, and rental income generally can’t be used to qualify. If renting in Big Sky is the main plan, expect investment-property financing instead, and make sure local short-term rental rules allow your plan first.
