Thinking about buying in Big Sky and opening the door to short-term rental income? The answer is not as simple as “yes” or “no.” Rules can change from one parcel to the next based on zoning, resort districts, and HOA covenants. You want clarity before you write an offer or build a pro forma. In this guide, you’ll learn what to check, who to call, and how to stay compliant so your investment performs the way you expect. Let’s dive in.
Confirm your jurisdiction first
Before anything else, pin down which rules actually apply to your property. Big Sky sits within Gallatin County and includes multiple planning areas, special service districts, and private HOA communities. The specifics change by parcel.
Who to call first
- Gallatin County Planning and Permit office for land use, zoning, and permitted uses.
- Any local resort-area or improvement districts that cover the property for potential lodging rules and fees.
- County Clerk, Treasurer, or local tax office for lodging or tourism taxes and business registration.
- The HOA management company and recorded CC&Rs for private rental restrictions.
Tip: Ask the seller’s agent for the parcel ID, then confirm with county planning whether any overlay or resort district applies.
Understand the rules that govern STRs
Short-term rental compliance usually falls into a few buckets. You will likely deal with more than one.
Zoning and land use
Check if STRs are permitted, conditional, restricted, or prohibited in the property’s zoning district. Also confirm any overlay or special resort rules. Pay attention to items like parking requirements, commercial use limits in residential zones, and whether accessory units follow different standards.
Registration and permits
Many areas require owners to register or obtain a permit before renting. You may need a registration number for listings, a local 24-7 contact, and proof you meet safety standards. Ask about application fees, renewal timelines, and whether you must report occupancy or gross receipts.
Life safety and occupancy
Plan for smoke and carbon monoxide detectors, proper egress, posted emergency contacts, and potential safety inspections. If the home has a septic system, capacity may limit guest counts. Utilities and wastewater limits can directly affect your listing’s maximum occupancy.
Noise, parking, and compatibility
Expect rules on quiet hours, on-site parking minimums, trash storage, and guest behavior. Noncompliance often triggers fines and can put your ability to operate at risk.
HOA and deed restrictions
HOA documents often control rental use. Common items include minimum rental periods, caps on total rentals, guest rules, parking requirements, and additional insurance standards. Request the full governing documents and any rental policies, plus meeting minutes that show prior enforcement or proposed changes.
Enforcement and penalties
Enforcement can be administrative, civil, or in repeat cases criminal if local code allows. Many areas escalate penalties for repeat violations. HOAs can also impose fines or pursue legal remedies for covenant breaches.
Know your taxes and costs
Short-term rentals carry ongoing fiscal obligations. Build these into your underwriting from day one.
Lodging and resort taxes
Local lodging or resort taxes may apply in addition to state and federal income taxes. Confirm whether you or the platform must collect and remit, the current rate, and the filing schedule. Also check for any special improvement district fees.
Business registration and reporting
Some jurisdictions require business registration and periodic occupancy or receipts reporting. Ask about forms, deadlines, and penalties for late filings.
Property tax and valuation
STR use can affect classification and assessment in some places. Contact the county assessor to understand how rental use may impact property taxes for your specific parcel.
Income tax and out-of-state owners
Rental income is taxable. Work with a CPA to plan for deductions, depreciation, and passive activity rules. If you live outside Montana, confirm any state-specific filing or withholding requirements.
Insurance and lending
Standard homeowner policies often exclude STR activity. You will want coverage that includes guest liability, property damage, and loss of rental income. Lenders may require you to disclose STR plans, and some loan programs limit or condition rental use. Ask your lender and insurance agent to price STR-specific terms in advance.
Big Sky market and operations
Operational details in a mountain resort market can make or break your returns.
Demand and seasonality
Big Sky demand peaks in the winter ski season and varies in the summer with hiking, rafting, and events. Seasonality impacts pricing, cash flow, and turnover scheduling. Build conservative assumptions for low-shoulder periods.
Infrastructure and access
Confirm whether the home is on municipal services or private well and septic. Evaluate winter road access, parking availability, snow removal, and fuel sources. Infrastructure constraints can reduce occupancy or require capital improvements.
Platforms and compliance
Major platforms offer compliance tools in some markets, but the responsibility to register, post the correct number, and remit any taxes usually sits with you. Check for any minimum-stay rules and whether noncompliant listings risk removal.
Property management
In a remote resort area, reliable local management is critical. Expect management fees that reflect full-service turnover and guest support. Factor in cleaning logistics, snow removal, vendor availability, and rapid guest response needs.
Buyer due diligence checklist
Use this list to validate a property before you commit:
- Confirm parcel jurisdiction. Ask county planning to verify zoning, overlays, and any resort or special improvement districts for the parcel ID.
- Obtain seller disclosures on prior STR use. Request copies of past permits or registrations, seasonal occupancy history, lodging tax filings if available, and any management agreements or complaint records.
- Review HOA and CC&Rs. Collect full governing documents and rental policies, plus meeting minutes that show enforcement history or pending rule changes.
- Verify zoning and permitted uses. Request a written zoning verification from county planning and ask about any prior conditional-use approvals for STR activity.
- Confirm registration and tax obligations. Ask the tax or tourism office about required registration, current lodging tax rates, filing frequency, and whether platforms remit on your behalf.
- Check building, septic, and occupancy compliance. Review septic inspections, building permits for conversions, and proof of smoke and CO detectors and other safety gear.
- Ask about enforcement processes. Inquire how complaints are handled, typical penalty structures, and whether enforcement history is available for the address.
- Speak with local property managers. Get realistic projections for occupancy, average daily rates, guest profiles, and full operating costs.
- Line up insurance and lending. Secure quotes for STR coverage and confirm your loan’s terms for rental use.
- Model conservative scenarios. Stress test your numbers with lower occupancy, higher costs, and potential rule changes or moratoria.
Risks to plan for
- Regulatory changes that add caps, stricter permits, or new residency rules.
- Neighborhood conflicts tied to noise, parking, or trash that trigger complaints.
- Septic capacity and winter access limits that reduce feasible guest counts.
- Ongoing compliance work for taxes, reporting, and renewals that add time and cost.
- Attractive nightly rates that can be offset by HOA restrictions or permit limits.
Your next steps
