Market Overview
Idaho just became one of the most STR-friendly states in the country. House Bill 583, signed March 16, 2026 and effective July 1, 2026, amended Idaho Code 67-6539 to bar any city or county from requiring a license, fee, permit, certification, or registration to operate a short-term rental, and to classify STRs as ‘nontransient residential use’ for zoning, meaning they cannot be zoned out of residential districts. Local governments can still require basic life-safety measures (smoke alarms in sleeping areas, fire extinguishers and carbon monoxide detectors on each floor, escape ladders for upper-floor sleeping rooms, building-code occupancy limits, and an emergency-info handout) and enforce ordinary noise, parking, nuisance, and traffic rules, but nothing beyond that.
Irwin is a tiny community of 308 residents on the Snake River in eastern Idaho’s Bonneville County, near the Wyoming line, functioning as a gateway for anglers, boaters and campers drawn to Palisades Reservoir and the blue-ribbon trout waters of the South Fork of the Snake River just below Palisades Dam. It also sits along the route through Swan Valley toward Grand Teton and Jackson Hole.
StaySTRA’s Airbnb/Vrbo performance data for this area is tracked at a shared regional level with Rigby and Swan Valley rather than uniquely for Irwin; treat the following as the eastern Idaho area STR market.

Short-Term Rental Regulations
Irwin is a very small community in Bonneville County, Idaho, and STR rules here are governed almost entirely by Idaho state law rather than any local Irwin-specific ordinance. Idaho Code 67-6539, strengthened by 2026 House Bill 583 (signed March 16, 2026, effective July 1, 2026), broadly preempts local short-term rental restrictions: no county or city may require a license, fee, permit, certification, or registration to operate a short-term rental, and STRs must be treated as ordinary residential use for zoning purposes.
Local governments can only require basic life-safety measures: smoke alarms in sleeping areas, fire extinguishers and carbon monoxide detectors on each floor, escape ladders for upper-floor sleeping areas, occupancy limits per building code, and an emergency-information handout. They can also enforce generally applicable ordinances on noise, parking, nuisance, and traffic.
There is no owner-occupancy or primary-residence requirement and no cap on rental nights. On taxes, STR stays of 30 days or less owe Idaho’s 6% state sales tax plus the 2% state Travel and Convention (lodging) tax, about 8% combined. Irwin and Bonneville County are not in an auditorium district (unlike Boise or Idaho Falls city), so no extra auditorium-district tax applies.
Airbnb and Vrbo-type marketplaces collect and remit these taxes automatically; a host renting only through such marketplaces needs no state tax permit, but must obtain an Idaho seller’s or travel-convention permit if renting directly or charging fees the marketplace does not tax. Overall, this is one of the most STR-friendly regulatory environments in the country.
Market Comparison
National benchmarks put the median U.S. short-term rental market at roughly 55% occupancy and a $220 ADR. The eastern Idaho area STR market that includes Irwin runs well above both, at 78.6% occupancy and a $374 ADR in June 2026, one of the strongest occupancy readings in this entire batch, reflecting concentrated summer fishing and reservoir-recreation demand.
Irwin’s regulatory environment is also a standout: Idaho’s new statewide preemption (House Bill 583, effective July 1, 2026) bars any local STR license, fee, or permit requirement, a lighter regulatory bar than every other market in this batch and most markets StaySTRA tracks nationally.
StaySTRA does not have top property-manager listings, review counts, or ratings on file for this market; that data is tracked at a shared regional level rather than uniquely for Irwin, so this profile omits named-operator comparisons rather than estimate them.
