Idaho Preempted Cities From Regulating STRs. Here Is How Cities Are Fighting Back Anyway.

Rep. Jordan Redman represents Coeur d’Alene in the Idaho House. His city officially opposed the short-term rental preemption bill he sponsored. He won anyway. On March 16, 2026, Governor Brad Little signed House Bill 583 into law, making Idaho the strictest state-level STR preemption jurisdiction in the country. On July 1, roughly ten weeks from today, every Idaho city loses the authority it has been using to regulate vacation rentals for the past four years.

The cities are not fighting back in court. They are quietly rewriting their ordinances to match what HB 583 allows, which is almost nothing.

This is the story of what happens after the preemption wave crashes.

What HB 583 Actually Prohibits

The bill text reads like a checklist of every regulation Idaho resort cities spent the last decade writing. Section 2(a) enumerates seventeen specific things cities and counties can no longer require. The list is worth reading carefully if you own an Idaho STR.

Cities cannot require owner occupation, professional property management, additional insurance, usage reporting, fire sprinklers, extra parking, physical structure modifications, inspections, signage, day-limits on rentals, neighbor notifications, increased utility capacity, conditional use permits, proximity limits between STRs, or caps on the total number of STRs in the jurisdiction. Section 5 adds the kill shot. No city “shall require a license, fee, permit, certification, or registration to operate a short-term rental.”

Section 3 tells cities what they still can do. Five things. All safety. Smoke alarms in sleeping areas. A functioning fire extinguisher and carbon monoxide detector on each floor. Removable escape ladders in bedrooms with windows above the ground floor. Maximum occupancy limits that match the International Building Code (so no city-specific math). And an informational handout listing exits, first aid kits, and the owner’s phone number.

That is the entire regulatory toolkit for the next forty-plus years of Idaho vacation rental policy.

Sandpoint Saw It Coming and Scrambled Anyway

On February 4, 2026, the Sandpoint City Council met to vote on a revised STR ordinance. The old rules included a cap on the number of permits the city would issue. STR lobbyists had been telling Sandpoint officials since 2025 that they would sue over the cap. The new ordinance removed the cap. It kept occupancy categories, permitting, parking requirements, and administrative procedures. Mayor Jeremy Grimm broke a tie vote to pass it.

At the top of that same meeting, Planning and Community Development Director Jason Welker told councilors the truth about HB 583, which was then still working through the Senate. “Basically it supersedes cities’ ability to regulate STRs at all,” Welker said, according to the Sandpoint Reader’s reporting.

The council voted unanimously. Then the governor signed HB 583 six weeks later. Every provision the council had just adopted, except the ones matching the state’s five safety items, was instantly set to become unenforceable on July 1. “Staff will wait and see if the governor signs the bill,” Welker said, “and, if he does, get to work on rewriting our STR ordinance to reflect only what is allowed under the new state law.”

Mayor Grimm’s public statement after the signing did not mince words. “Cities now have no ability to determine where short-term rentals should operate and how they should be managed. That decision has effectively been centralized at the state level, even though communities across Idaho differ dramatically in their housing markets, infrastructure capacity and neighborhood patterns.”

He added a warning about what he believes comes next. “When residential homes are removed from the long-term housing market and converted into short-term rentals, the supply of housing available to local employees shrinks. The pressure on prices increases, and employers struggle to retain workers.”

That is as close to a promise of future legislative fights as Idaho mayors are making right now. Sandpoint is not suing. Neither is anyone else.

McCall Loses the Most

McCall, population 3,200, hosts roughly 600,000 visitors a year. StaySTRA market data shows 748 active short-term rentals in the city, which works out to nearly one vacation rental for every four full-time residents. The average daily rate is $309.58. Monthly revenue averages $2,950. During peak July demand, occupancy hits 87.1 percent.

McCall built a detailed STR regulatory framework in 2022. That framework included a special permitting process, mandatory annual fire safety inspections, and city-calculated occupancy limits. The annual fire inspections were the city’s main tool for checking whether properties marketed as five-bedroom cabins actually met fire code at five-bedroom capacity. All of that becomes unenforceable July 1.

The Idaho Resort Cities Coalition, which represents Ketchum, McCall, Lava Hot Springs, and Driggs, lobbied hard against HB 583. They backed a competing bill, SB 1263, that would have kept more local authority. SB 1263 died in committee. During the session, McCall city staff sent text alerts to residents urging them to testify against HB 583. The testimony did not move the votes. The final Senate margin was 23-12.

McCall has not announced a legal challenge. No Idaho city has.

Ketchum’s $504 Permit Fee Ends July 1

Sixteen miles south of Sun Valley, Ketchum operates under Municipal Code Chapter 5.09, Ordinance #1230, which took effect April 1, 2022. The application fee is $504 for new permits and $504 for renewals. The city requires a Fire Life Safety Plan, a designated local representative within two miles of city limits, a two-night minimum stay, and one STR per parcel.

Every one of those requirements except the safety plan’s fire equipment components is preempted by HB 583. The $504 fee disappears. The two-night minimum disappears. The one-STR-per-parcel limit disappears. Ketchum can still require smoke alarms and escape ladders. That is the list.

As of this reporting, Ketchum’s official STR page still lists the $504 fee and the existing requirements with no notice about the July 1 changes. Hosts applying for a permit in May will be paying for a license that the state is about to strip of legal force. The city’s email for STR questions, [email protected], will presumably get busy in June.

For context on what is at stake in the Sun Valley corridor, StaySTRA data for neighboring Hailey shows 137 active STRs at a $283 ADR with 63 percent occupancy. Winter ski-season occupancy pushes above 80 percent. This is a market where the permit fees were real overhead for small operators, and that overhead is about to vanish.

Boise’s $80 License Was the Cheap Version

Boise’s existing ordinance under Chapter 22 of the city code requires an annual STR license for $80 plus a processing charge. By Idaho resort city standards, that was light regulation. By HB 583 standards, it is still illegal as of July 1.

Boise has 1,684 active short-term rentals according to StaySTRA market data, with an average daily rate of $162.80 and 81 percent occupancy as of June 2025. This is the volume market. The city’s code compliance team has been using the license program as a way to track addresses, contact owners, and route noise complaints. After July 1, the city keeps its noise ordinance and its parking rules. It loses the registry.

Nobody at Boise City Hall is on record saying this is a crisis. The city is not part of the Resort Cities Coalition, and Boise’s STR density is far lower than McCall’s or Ketchum’s relative to housing stock. Urban staff tend to see the permit fee more as an administrative cost-recovery line item than as a housing policy tool. The political heat around HB 583 came from the resort towns, not from Boise.

Why No City Is Suing

I asked the question you would expect an investigative reporter to ask. Why has no Idaho city filed a legal challenge against HB 583 given the unified opposition from the Association of Idaho Cities, the Resort Cities Coalition, and individual municipalities?

The answer comes down to five practical realities.

First, Idaho is a Dillon’s Rule state. Cities are creatures of the state legislature, and the legislature has broad constitutional authority to preempt local ordinances. There is no home-rule doctrine to invoke. A constitutional challenge to HB 583 would be an uphill fight on weak ground.

Second, cities are already exposed to lawsuits going the other direction. Sandpoint’s 2025 experience, where STR industry lobbyists warned the city they would sue over its permit cap, shows that cities face litigation risk if they enforce too much. Trying to enforce a preempted ordinance would invite a certain loss.

Third, small resort cities have limited legal budgets. McCall’s annual budget does not accommodate a multi-year preemption challenge against the state.

Fourth, the July 1 deadline is too fast. Coordinated legal action among multiple cities would require months of advance planning and funding commitments. The bill was signed March 16. There is no realistic path to a preliminary injunction before the effective date.

Fifth, the bill is cleanly drafted. The seventeen enumerated prohibitions and the five allowed safety requirements are specific and limit the ambiguity that litigation usually exploits. There is no vague standard to attack.

Cities are instead doing what Welker described. They are rewriting their ordinances to match what is allowed and saving their political capital for the next legislative session. Mayor Grimm’s comments about employee housing read like the opening statement for a 2027 or 2028 bill.

What Idaho STR Owners Should Actually Do

For hosts and investors with existing Idaho properties, July 1 is operational. A few concrete actions make sense between now and then.

Verify your safety compliance against the five items Idaho cities can still enforce. Smoke alarms in every sleeping area, living room, basement, and family room. A working fire extinguisher and a carbon monoxide detector on every floor. Removable escape ladders in every bedroom with a window above the ground floor. The informational handout with exits, first aid location, and the manager’s phone number. Occupancy at the International Building Code non-transient residential standard. That list is the floor, and it is also the ceiling.

Do not pay a permit renewal fee that will expire before it matters. If your Ketchum or Boise permit comes up for renewal in May or June, call the city first and ask whether the fee is still being charged. Cities should be prorating or waiving those fees, though not all will volunteer to do so.

Keep paying your lodging taxes. HB 583’s tax section amends Idaho Code 63-1804 to route marketplace tax collection through the state tax commission. Airbnb and Vrbo will continue to collect occupancy taxes, and direct-booking hosts must register with the state within 45 days of their first lodging transaction. The state keeps the tax pipeline. The city loses the permit pipeline.

Do not stop following general residential ordinances. Noise, parking, nuisance, curfew, and traffic rules still apply. A neighbor can still call the city about your guests’ 2 a.m. party. The enforcement mechanism just runs through the same code compliance officer who handles long-term rental complaints, not through a dedicated STR inspector.

For new investors, the case for Idaho just got stronger. The regulatory floor is set by state law, not by the mood of a seven-member city council. That stability is exactly what institutional capital values. Expect more professionally operated STRs entering markets like McCall, Sandpoint, and Hailey over the next two years.

The Preemption Wave in Context

Idaho is the leading edge of a 2026 pattern. Indiana passed similar language. Tennessee is considering a version of the Idaho approach. Texas, New Mexico, and other states have watched what happened in Idaho and are weighing their own bills. Arizona, which passed preemption earlier, is now partially rolling it back after years of complaint from municipalities. The movement is not uniform, and the long arc has not been written.

For a deeper look at the national picture, our coverage of the 2026 STR preemption wave across state legislatures tracks each state’s position. Our analysis of which states are next after Idaho looks at where this movement is heading.

What Idaho shows, though, is the end state. Once a preemption bill passes with a clean enumerated list and an emergency clause, the cities do not fight in court. They fight in the next legislative session. And they start by collecting data on housing displacement and workforce pressure, which is precisely what Mayor Grimm telegraphed in his post-signing statement.

The investors who will do best in Idaho between now and 2028 are the ones who treat July 1, 2026 as a reset date, not a finish line. The regulatory picture is stable for now. The political picture is not.
