Overview: Are Short-Term Rentals Allowed in Polson, MT?

Yes—short-term rentals (STRs) are allowed in Polson, Montana, but only where zoning permits them and with full licensing and permitting compliance. Polson lies within Lake County; the city does not have separate STR ordinances, so operations must follow county zoning rules, environmental health requirements, building codes, state health and lodging tax regulations, and any local covenants or HOA rules. As a practical rule, confirm zoning with Lake County Planning before acquiring or converting a property. If you proceed correctly, Lake County will license and inspect your STR as a “public accommodation” (public sleeping accommodation). If you operate without required approvals, you risk immediate regulatory intervention.

Jurisdiction Snapshot

• Governing jurisdiction for STRs: Lake County (Polson has no separate STR code).
• City-level rules: None specific to STRs; defer to Lake County and state law.
• State-level overlays: Montana public accommodation licensing and lodging taxes apply.
