Can I Airbnb in Twin Falls? 2026 Short-Term Rental Rules

Is Airbnb legal in Twin Falls?

Twin Falls (zip 83301) is Idaho's most consistent year-round cash-flow STR market, ranked the #3 hottest zip code in Idaho for in-migration in 2025 and rated by SummerOS as the top Idaho market for year-round occupancy and reliable cash flow. AirROI's 2026 dataset shows $24,447/yr average revenue at $179/night ADR and 46.3% occupancy — with supply up 55.5% YoY yet both revenue and nightly rates still trending upward. The average Twin Falls home sold at ~$360K. Under HB 583 (effective July 1, 2026), no STR-specific permit, fee, or registration can be required. AirROI flags regulation as 'low with minimal registration requirements.' The broad appeal of Snake River Canyon tourism and Shoshone Falls provides a diversified guest base reducing seasonality risk. Recent/pending changes: The single most significant recent change is Idaho HB 583, signed March 16, 2026 and effective July 1, 2026, which established what has been described as the broadest state-level STR preemption in the country — barring local licensing, fees, permits, density caps, and discriminatory zoning. This supersedes any prior Twin Falls registration requirements. The Idaho Legislature has attempted STR preemption bills in 2024, 2025, and 2026 — the 2026 version finally passed. Some legislators have signaled the balance between state preemption and local control may be revisited in future sessions.
