Idaho just handed STR operators the most operator-friendly state law in the country. Meanwhile, AirDNA's data points to Idaho and Wyoming as two of the strongest state-level markets for returns. The Mountain West is moving in the opposite direction from every coastal market right now.
MARKET INTEL
Idaho's new law changes the game for operators — effective July 1.
On March 16, 2026, Governor Brad Little signed House Bill 583, the broadest state-level preemption of local STR regulation in the country. The bill passed the House 54–16 and the Senate 23–12 after three years of failed attempts.
Here's what it actually means for operators: starting July 1, Idaho cities and counties cannot require a license, permit, fee, or registration to run a short-term rental. No density caps. No owner-occupancy requirements. No day limits. No additional insurance mandates. STRs are now classified as "non-transient residential use" — meaning they're treated the same as any other home for zoning purposes.
If a city can't require it of a regular homeowner, it can't require it of you.
McCall had one of the most restrictive permit systems in the state — mandatory fire inspections, city-calculated occupancy limits, professional management requirements. All of it gets repealed before July 1 or it's unenforceable.
Local governments do keep authority over noise, parking, and nuisance rules, and can require basic safety items like smoke detectors — as long as those rules apply to all residential properties equally.
The practical implication: if you've been holding back on adding Idaho inventory because of regulatory risk, that calculus just changed. Idaho joins Arizona and Tennessee as states with meaningful preemption. What happens in resort markets — McCall, Coeur d'Alene, Sun Valley — over the next 12 months will be worth watching closely.
OPERATOR PLAYBOOK
Run the Idaho opportunity through a real underwriting filter before everyone else does.
AirDNA's latest state-level market data points to Idaho and Wyoming as two of the stronger STR opportunities nationally — driven by affordability relative to returns, outdoor tourism demand, and destination travel that doesn't depend on a single seasonal window.
Before you move, here's the framework to apply right now:
Check the regulatory window. HB 583 takes effect July 1. Between now and then, local governments are reviewing which ordinances conflict with the new law. Some will try to pass new restrictions framed as "general residential rules" before the deadline. Watch your target market's city council agenda for the next 60 days.
Look at entry price vs. revenue potential. The markets AirDNA highlights in the Mountain West benefit from a specific gap: lower purchase prices relative to annual STR revenue. That gap is narrowing in coastal markets. Wyoming and Idaho still have room on that spread, particularly in secondary and tertiary markets outside Jackson.
Focus on demand drivers that aren't seasonal. Jackson runs on ski and summer outdoor tourism. That's real, but it also means two shoulder periods. Markets with year-round drivers — national park adjacency, fishing, hunting, ATV, and snowmobile traffic — smooth out your occupancy curve. Think Dubois, Cody, eastern Idaho.
Model the tax side now. HB 583 requires STR operators who book direct (not through a platform) to register with the Idaho State Tax Commission and remit state and local lodging taxes independently. Platforms like Airbnb collect automatically. If you're driving direct bookings — and you should be — get your tax registration handled before July 1.
DEAL SPOTLIGHT
The secondary Wyoming market thesis is getting stronger.
As Jackson valuations stay elevated and permit availability tightens, the operator math increasingly points to secondary Wyoming markets. Cody gets 2M+ visitors annually via Yellowstone's east entrance. Dubois sits at the junction of two major highway corridors. Thermopolis draws medical tourism and year-round hot springs traffic.
What these markets share: sub-$400K entry points on properties that can generate $40–60K in gross STR revenue, thin existing supply, and no meaningful permit risk under Wyoming's current regulatory environment.
The window before these markets get discovered is shorter than it was 18 months ago. If you're running a buy-box analysis right now, add eastern Wyoming to the filter.
