Short-Term Rental Regulations
Short-term rentals are explicitly legal in Island Park and throughout Fremont County. Idaho House Bill 216 (2017) prohibits cities and counties from banning STRs outright, limiting local governments to reasonable health and safety regulations. Permitting is administered by Fremont County’s Planning and Building Department. Any rental of fewer than 30 days requires an annual Transient Lodging Permit. Permits come in two classes based on guest capacity: Class 1 covers up to 15 guests at $200 per year, and Class 2 covers 16 to 30 guests. Both permit classes require septic system and well water inspections every two years. There is no maximum night cap per year, no owner-occupancy requirement, and no primary-residence requirement, making this one of Idaho’s most permissive STR environments. Tax obligations include the 6% Idaho state sales tax plus the 2% statewide Travel and Convention tax, for a combined 8% on stays under 30 days. Island Park has no local-option or resort-city lodging tax. Enforcement is described as minimal: Fremont County has only three planning and zoning staff for the entire county, and the compliance approach favors getting unpermitted owners into compliance following a complaint rather than imposing fines. As of early 2026, Idaho lawmakers were reported to be considering further limits on local control over STRs, which would reinforce the existing state preemption.
Market Comparison
Island Park’s April 2026 occupancy of 50.8% sits just below the U.S. STR median of approximately 55%, which is expected given April falls in the spring shoulder before summer demand peaks. The ADR of $155.88 is well below the national median of roughly $220, reflecting the predominance of cabins and rural lodging rather than urban or coastal premium properties. The revenue growth score of 82.4 out of 100 places Island Park among higher-growth markets nationally despite the below-average ADR. The top property management firm in the market is Island Park Reservations with 79 listings and 3,841 reviews at a 4.71 average rating, followed by Prime Properties with 67 listings and 4.85 rating, and Evolve with 59 listings and a 4.76 rating. These three operators collectively manage approximately 205 of the roughly 2,749 total listings, representing about 7.5% of the market. The remaining majority of the market is operated by individual owners, which is typical of rural cabin destinations. Kabino and Vacation Rental Management LLC round out the top five at 49 and 48 listings respectively.
