"Without registration, we don't have the basic contact information to address issues with the owner." That's what Ketchum spokesman Daniel Hansen told the Idaho Mountain Express earlier this year, describing what the city was about to lose. He was right. As of July 1, 2026, Ketchum can no longer require a permit, a fee, a registration, or a city-approved fire safety plan just to operate a short-term rental. The tool the city used to track who owned what, and to make a new owner reapply the moment a property changed hands, is off the books.
If you're buying or selling a short-term rental in Ketchum this fall, that sounds like good news, and in one narrow sense it is. But the due diligence didn't get lighter. It got relocated. The city stopped being the gatekeeper. The homeowners association became the one that matters.
What Ordinance 1230 Actually Required, and Why It Mattered at Closing
Since 2022, Ketchum's Ordinance 1230 governed short-term rentals with a fair amount of specificity: a $504 annual permit fee, a fire life safety plan reviewed and approved by the Ketchum Fire District, city-conducted inspections, a local representative living within 20 vehicular miles who could respond to complaints, and a minimum two-night stay. The part that mattered most at the closing table was simpler and blunter: the permit ended when the property sold. A new owner didn't inherit the seller's permit. They had to apply for their own, which meant a gap between closing and the day they could legally list the unit again.
That gap is exactly the kind of thing that shows up mid-escrow and forces a renegotiation, because a buyer who assumed rental income would start on day one suddenly has to wait on a city approval that has nothing to do with the property itself and everything to do with paperwork.
Ketchum ran one of the more detailed STR permitting programs in Idaho, generating roughly $100,000 a year in city revenue from permit fees and renewals. That revenue and the compliance apparatus behind it are what House Bill 583 targeted.
The State Law That Forced the Change
Idaho Governor Brad Little signed HB 583 on March 16, 2026. It carried an emergency clause, so it took effect July 1, 2026, giving cities roughly three and a half months to bring local ordinances into line. The bill passed the House 54 to 16 and the Senate 23 to 12, sponsored by Rep. Jordan Redman of Coeur d'Alene, and it was the third year in a row the legislature took up the question of how much authority cities and counties have over short-term rentals.
What it does is specific: it bars local governments from requiring a license, fee, permit, certification, or registration to operate a short-term rental, and it classifies short-term rentals as a "nontransient residential use" for zoning and building code purposes, putting them on the same footing as any other home. Melissa Radford, vice president of advocacy at the Idaho Vacation Rental Association, described it as establishing "a clear and consistent standard for how Idaho treats homeowners who rent their property."
Ketchum's City Council responded by moving to repeal the permit process, the mandatory inspections, and the fire-safety-plan approval requirement built into Ordinance 1230. City Administrator Jade Riley told the council the underlying safety practices would become optional but still recommended, and Councilman Spencer Cordovano noted that several operators he'd spoken with planned to keep following the old standards voluntarily, treating them as best practice rather than obligation.
Here's what that shift looks like side by side:
| Requirement | Before July 1, 2026 | After July 1, 2026 |
|---|---|---|
| City STR permit and $504 annual fee | Required | No longer required |
| Fire safety plan approved by Ketchum Fire District | Required | Voluntary |
| City-conducted inspections | Authorized | No longer authorized |
| Permit status on sale | Terminated automatically, new owner had to reapply | No permit exists to terminate |
| Minimum two-night stay, one STR per parcel | City ordinance | Still applies to residential rentals generally |
| Noise ordinance (audible beyond property line, 10 p.m. to 8 a.m.) | In effect | In effect, unchanged |
| HOA or CC&R rental restrictions | Enforceable per governing documents | Enforceable per governing documents, unaffected by HB 583 |
What Didn't Change, and Why It's the Part That Matters Now
HB 583 does not touch private governance. Homeowners associations in Ketchum and the wider Sun Valley area keep full authority to restrict or ban short-term rentals through their CC&Rs, and that authority was never the city's to begin with. If a condo association in the core or a subdivision closer to Warm Springs has a rental restriction in its governing documents, that restriction still controls, regardless of what the state just did to city permitting.
There's a wrinkle worth understanding before you write an offer or list a property. Idaho Code §55-3211 limits an HOA's ability to impose a new rental ban on an owner who already bought under different rules, unless that owner agreed to the change in writing. So a covenant adopted after you purchased generally can't be used against you retroactively. But a restriction that was already in the CC&Rs at the time of your purchase, or a buyer's purchase, remains enforceable exactly as written. That means the due diligence question a buyer needs answered isn't "does the city allow this," which used to be the whole conversation. It's "what do the CC&Rs say, and when were they adopted relative to this specific unit's ownership history."
Ketchum's Avalanche Zone District rule is a separate case that survives the state law cleanly, because it was never written as an STR-specific restriction. Under Ketchum Municipal Code 17.92.010, any residence in that zone that hasn't been engineered to withstand avalanche forces can't be leased, rented, or sublet from November 15 through April 15, and that limit applies to any rental, short or long term, which is exactly the kind of even-handed rule HB 583 was designed to leave in place. If a property sits in that zone, it's worth confirming engineering status before assuming winter rental income is available at all.
Local option lodging taxes, state sales tax, and the state's two percent Travel and Convention Tax also carry forward untouched. Platforms like Airbnb and Vrbo generally collect and remit those on bookings made through their systems. An owner who takes direct bookings is still responsible for registering with the Idaho State Tax Commission and handling that themselves.
A Shorter Due Diligence List, Not a Vanished One
For a buyer or seller working through an STR transaction in Ketchum right now, the checklist looks different than it did a year ago, but it isn't gone:
- Pull the CC&Rs and any amendments for the specific building or subdivision, and note when each rental-related provision was adopted.
- Confirm whether the property sits in the Avalanche Zone District and whether it's been engineered accordingly, since that limit still governs winter rentals regardless of state law.
- Ask whether the seller has been operating under a voluntary fire safety plan or the old city standards, since some owners are keeping those practices even though they're no longer mandatory.
- Verify how lodging taxes have been handled, particularly if the property has taken direct bookings outside a platform.
- If financing, confirm with the lender how the unit's rental history and HOA rules affect condo warrantability, since that underwriting question hasn't changed.
Ketchum and Sun Valley together account for roughly 81 percent of the Wood River Valley's short-term rental units, based on 2024 figures, which is part of why this particular regulatory shift lands harder here than it does in Hailey or Bellevue. Most of the valley's STR inventory, and most of the transaction volume tied to it, sits in these two towns. A change to how permitting works in Ketchum isn't a footnote for the local market. It's a change to how a meaningful share of the valley's resort real estate gets bought, sold, and priced.
A Few Direct Answers
Does a short-term rental permit still transfer with the sale of a Ketchum property? There's no longer a city permit to transfer. The mechanism that used to end automatically at closing and require the buyer to reapply has been repealed along with the rest of Ketchum's permit program.
Can an HOA still stop me from short-term renting a unit I'm about to buy? Yes, if the restriction was already written into the CC&Rs before your purchase. HB 583 changed what cities can require. It didn't change what a homeowners association can restrict through its own governing documents.
Do I still need to worry about fire safety requirements? The city can no longer mandate a fire-safety-plan review as a condition of operating, but several Ketchum owners are keeping their existing plans in place voluntarily, and it's a reasonable thing to ask a seller about during due diligence even though it's no longer a legal requirement.
Regulatory shifts like this one tend to move faster than most buyers or sellers can track on their own, especially when the meaningful risk quietly moves from a city ordinance to a stack of CC&Rs nobody's read since closing.
