Idaho's HB 583 took effect on July 1, and the City of Ketchum is now repealing the ordinance that required a permit to operate a short-term rental.
If you're shopping for an income property in this valley, the headline reads like a win. Less regulation, lower cost of entry, one fewer hoop before the first booking.
The headline isn't wrong, but it's pointed at the smallest part of what happened. The permit cost $504 per property per year — meaningful for someone holding several units, still modest against valley pricing. What the permit also did was create a public touchpoint between the city and the operator. That touchpoint is going away, and the compliance obligations behind it are not.
What did HB 583 actually change?
HB 583, signed in March 2026 and effective July 1, reclassifies short-term rentals as "nontransient residential use" and bars cities from requiring STR-specific permits, licensing, or inspections. Ketchum is repealing its Chapter 5.09 permit program through Ordinance 1277. The program had been generating roughly $100,000 a year for the city.
Ketchum was the natural focus. Reporting on the valley's rental market has put roughly 840 short-term rental units in operation as of 2024, with about 81% of them concentrated in Ketchum and Sun Valley combined — though that figure comes from a secondary source and the underlying count is worth confirming with the cities directly.
Worth saying plainly: what follows describes reporting on a statute, not a reading of one. Before you underwrite a purchase on the strength of any of it, have a real estate attorney review the current text and whatever local ordinances remain.
Why isn't the $504 the story?
Because the permit was doing something besides collecting a fee.
Cities retain authority over life-safety requirements — smoke and carbon monoxide alarms, extinguishers, egress from sleeping rooms — and over noise and nuisance rules. Those obligations survived HB 583 completely. What's ending is the STR-specific permitting and inspection process that sat alongside them.
I'd encourage you to confirm directly with the City of Ketchum what the permit process actually involved, because it determines how much diligence just shifted onto you. If it included an inspection, you've lost a verification step. If it was closer to registration, you've lost a registry. Either way you've lost a place to look something up, and the requirements themselves haven't moved.
That's the practical change: diligence that might have been answerable with a phone call to the city is now a line item on your inspection request.
Where does the real restriction live now?
Very possibly in the CC&Rs — and this is the part I'd want you to take seriously.
Preemption laws govern what cities can require of property owners. Recorded covenants are a different animal: private contracts among owners, enforced between them. I have not verified whether HB 583 addresses private covenants at all, and I'm not going to guess, because some states' preemption statutes do reach HOA authority and some don't. That is a question for your attorney and it is worth the hour.
What I'd tell you in the meantime is to assume your building's declaration still binds you until counsel says otherwise. If it prohibits stays under 30 days, treat that as live.
Look at where rental demand concentrates and you can see why this isn't academic. Condominiums were the valley's most active segment through the first half of 2026 — average sale price up 36% to $1.34 million, with unit sales rising from 55 to 72 over the same period in 2025, per Summer Baldwin's mid-year market update. Those are her calculations from MLS data rather than a published statistic, so treat them as directional.
Condos are where short-term rental buyers tend to shop. They're also governed by declarations that can differ unit to unit depending on when amendments were recorded and whether a minimum-stay provision was added. Neither the listing nor the city can tell you which version applies to the unit in front of you. Only the documents can.
How does this change the competition math?
It removes a barrier to entry, and barriers to entry affect supply.
I'm not going to tell you what nightly rates or occupancy will do, because I don't know and neither does anyone selling you a projection. What I'd interrogate is the assumption about competition. A model built on last year's occupancy against next year's inventory may be describing a market that no longer exists.
Active listings were down roughly 9% year-over-year as of late June in the same market update, which cuts the other way — fewer properties to buy, potentially more of them operating as rentals. Model both directions.
What else is still moving?
Ketchum has a local-option tax measure under discussion for the November 2026 ballot. As reported, it would combine a 0.5% retail increase, a 2% lodging increase, and a 0.5% building-materials increase, with the three together projected to raise around $2.2 million annually for transportation infrastructure.
A lodging tax lands on short-term rental operators. Whether the measure reaches the ballot and whether voters approve it are both open, and I won't guess at either. But if you're building a ten-year model on a Ketchum rental, it belongs in your sensitivity analysis rather than arriving as a surprise in 2027.
What would I check before writing an offer?
Six things, in this order:
- Pull the CC&Rs and every recorded amendment. Not the summary — the documents, including minimum-stay language and any rental caps.
- Get HOA meeting minutes for the past two years. Amendments get discussed before they get recorded.
- Confirm with the City of Ketchum what its permit process required, and what compliance obligations remain now that it's repealed.
- Verify life-safety compliance independently. Alarms, extinguishers, egress.
- Confirm documented rental history, not a pro forma.
- Have counsel review the current statute, remaining local ordinances, and the declaration before you rely on any of it.
None of this is exotic. It's diligence that a permit process may have partly done for you.
The part worth remembering
The regulatory environment for short-term rentals in Ketchum got simpler on July 1. Buying one did not.
Public requirements loosened. Private restrictions may now be the binding constraint. And a place where a buyer could go to check something has closed. For a buyer who reads documents, that's a market with less friction. For a buyer who assumed someone else was checking, it's a market with a new way to get hurt.
If you're evaluating an income property in the valley this fall, the useful conversation happens before you're under contract — while the documents are still something you can read rather than something you've already signed.

FAQ
Four questions the body doesn't cover.
Does HB 583 apply in Hailey and Bellevue too?
Yes. HB 583 is state law and preempts short-term rental permit requirements for Idaho cities generally, not just Ketchum. Ketchum drew the most attention because it had the most developed permit program and the highest concentration of rental units. Confirm current local ordinances in each city, since noise and life-safety rules still vary.
I already hold a Ketchum STR permit. What happens to it?
The permit program is being repealed, so the requirement goes away rather than the permit expiring. Contact the City of Ketchum directly about the status of existing permits and whether any fee refund applies — that's an administrative question the ordinance repeal may or may not address.
Does this change how my rental income is taxed?
No. HB 583 addresses land use classification and local permitting, not taxation. Idaho sales and travel and convention taxes on short-term lodging are separate, as is the homeowner's exemption question. Talk to a CPA.
Does the law apply to the City of Sun Valley as well as Ketchum?
Sun Valley is a separate incorporated city and is subject to the same state preemption. Because Sun Valley and Ketchum together held roughly 81% of the valley's rental units as of 2024, both are materially affected. Verify each city's remaining ordinances individually.
