Short-Term Rental Regulations
Short-term rentals are legal in Island Park. Idaho House Bill 216 (2017) bars cities and counties from banning them, so they are broadly permitted across residential zones, though counties may impose reasonable health and safety rules. Rentals of fewer than 30 days are regulated by the Fremont County Planning & Building Department rather than the City of Island Park.
Operators need a Fremont County Transient Lodging Permit, renewed annually. Class 1 covers up to 15 guests and costs $200 per year. Class 2 covers 16 to 30 guests and costs $500 per year. Both classes require septic and well inspections every two years, and occupancy limits are tied to the permit class.
There is no documented maximum number of nights per year. There is no owner-occupancy requirement and no primary-residence requirement.
Tax obligations are at the state level: 6% Idaho sales tax plus the 2% statewide Travel and Convention tax, 8% in total, on stays of 30 days or less. Island Park has no local-option or resort city tax.
Enforcement is rated minimal. The county has only three planning and zoning staff, an administrator estimated that about 60% of cabin rentals were permitted, and the approach favors getting owners permitted after a complaint rather than issuing fines. Reporting in February 2026 noted Idaho lawmakers moving to further curb local control over short-term rentals, which would reinforce the state preemption already in place. No new county ordinance from 2024 or 2025 was confirmed. Investors should still confirm current permit terms with Fremont County before buying.
Market Comparison
In September 2026 the Island Park area STR market ran at 66.7% occupancy and a $310 ADR, with entire homes at $323 and professionally managed listings at $448.
The comparison needs context. Island Park’s September performance reflects the tail of a strong summer season, and January occupancy of 34.8% is the lowest of the year. The market rewards operators who can capture the June through September window.
The area’s operator base is concentrated but not dominant. The top five property managers are Island Park Reservations with 79 listings and a 4.71 rating, Prime Properties with 67 listings and a 4.85 rating, Evolve with 59 listings and a 4.76 rating, Kabino with 49 listings and a 4.59 rating, and Vacation Rental Management LLC with 48 listings and a 4.95 rating. Together they manage 302 listings, about 11% of the Island Park area STR market’s 2,749 tracked listings, so independent owners still hold most of the supply. The StaySTRA market score of 66.5 out of 100 reflects strong revenue growth (82.4) and investability (73.2), offset by weaker seasonality (45.4).
