The transient rental tiers are still in Fremont County’s code book — and since July 1, 2026, they are not what you must do
What the code book still prints
Fremont County’s Development Code — the 2011 edition, consolidated through Ordinance 2026-03 — still carries a whole permit scheme for renting houses by the night. It defines the use by duration first:
“Transient rental lodging or occupancy means the use of a structure or some part thereof for rental or occupancy for sleeping or lodging for terms of 30 consecutive days or less, in exchange for a fee or other similar consideration.”
— Fremont County Development Code, 2011 Edition (Ordinance 2011-04), Appendix I §1.34, consolidated through Ordinance 2026-03. This is what the book PRINTS — see the statute below before acting on it. Retrieved 23 September 2026
And on that definition the book builds three tiers, gated by how many people sleep over:
| Tier | Overnight occupants | What the code printed |
|---|---|---|
| Minor transient use | 15 or fewer | Class I Residential Business/Lodging Permit |
| Expanded transient use | 16 to 30 | Class II Conditional Use Permit — notice and a public hearing |
| Major transient use | More than 30 | Defined as a commercial use needing commercial zoning |
Printed, the scheme is coherent: two permits, a hearing above sixteen sleepers, and a commercial cliff above thirty. The trouble is one sentence long, and it comes from the legislature, not the county.
The statute that switched it off
House Bill 583 passed in the 2026 session, amended Idaho Code §67-6539, and — by emergency clause — took effect July 1, 2026. The county code’s consolidation is current only through Ordinance 2026-03, months earlier. The operative sentence:
“No county or city shall require a license, fee, permit, certification, or registration to operate a short-term rental.”
— Idaho Code §67-6539(5), amended by the 2026 Idaho Legislature (HB 583, session law chapter 22), effective July 1, 2026. Retrieved from legislature.idaho.gov 23 September 2026
That one sentence retires both permits in the printed table. And the statute did not stop there — two more of its lines reach straight into Division 5’s machinery:
“A short-term rental shall be classified as a non-transient residential use for zoning and building code purposes and be subject to all zoning requirements applicable thereto…”
— Idaho Code §67-6539(1). Retrieved 23 September 2026
The zoning sentence is the one that settles the printed commercial cliff: under state law a nightly rental is a residential use for zoning purposes, whatever head count it sleeps. The statute’s list of barred “different restrictions or obligations” also names §67-6539(2)(a)(xiv): requiring a conditional use permit in a residential zone — the printed Class II hearing path, specifically — and (2)(a)(x): required signage, notices, or diagrams, which is where the printed posted-contact-agent rule lived.
Where each printed rule now stands
| Division 5, as printed | Status under §67-6539 |
|---|---|
| Class I permit (up to 15 occupants) | Barred — (5): no permit, license, fee, certification or registration to operate |
| Class II conditional use permit (16–30) | Barred specifically — (2)(a)(xiv): no required CUP in a residential zone |
| More than 30 = commercial use, commercial zoning | Displaced — (1) classifies a short-term rental as a non-transient residential use for zoning purposes |
| 150 square feet of heated habitable space per occupant | Superseded as a special STR arithmetic — the only occupancy limit a county may keep is §(3)(d)’s: no greater than the building code’s non-transient residential limits |
| Local agent’s name and number posted on the building | Barred as signage — (2)(a)(x); the guest-facing handout survives instead (see below) |
| Roadway-access requirement | Not an STR-specific obligation to the extent it applies to dwellings generally — access law for the lot itself is unchanged |
The short, closed list a county may still require
The statute does not leave regulation to guesswork. Section 3 permits a county or city to require, by ordinance, “the following requirements only”:
- Smoke alarms in all sleeping areas — including, where applicable, basements, living rooms and family rooms.
- A fire extinguisher and a carbon monoxide detector on each floor.
- Removable escape ladders in sleeping areas with a window above the ground floor.
- Occupancy limits no greater than the non-transient residential limits in the building codes the state board adopts.
- An informational handout for tenants: exits, extinguisher and first-aid locations, and a phone number for the owner or manager in an emergency.
Notice the last item — it is the printed posting rule’s surviving descendant. The county cannot make a rental post its agent’s number on the wall for neighbours to read, but the statute itself keeps an emergency-contact duty aimed at the guest. And §67-6539(6) preserves every ordinance that applies to residences generally: noise, parking, nuisance, curfew and traffic rules all still bind a rental exactly as they bind the house next door.
What none of this touches
- Recorded covenants. The statute limits what county and city governments may do. A subdivision’s recorded covenants are private law that runs with the land — what your plat and covenants say about rentals binds regardless of what the county is allowed to require.
- Sound. A lawful rental can still be an unlawful noise source at the wrong hours — the decibel rules are mapped on their own page, and they apply to rentals identically.
- Building more sleeping capacity. Adding a second dwelling to sleep more people is new construction — permits, setbacks, and the whole building-code conversation restart, untouched by anything in §67-6539.
Before you list the house
- Read the subdivision’s recorded covenants first — after July 2026 they are the strictest rental rules that can actually bind you.
- Ask the county what it currently administers for rentals — the printed scheme predates the statute, and what the desk enforces today is a fair question with a straight answer.
- Walk the safety list in §67-6539(3) whether or not a county ordinance exists: alarms, extinguisher, CO detectors, ladders, and the guest handout with your emergency number.
- Set your honest occupancy at the building code’s residential limit — and at what the house, well and systems were built for, which no statute re-sizes.
- Know the noise and nuisance ordinances that apply to you identically to every other house.
- Then call (208) 656-1516 and pressure-test the picture for your actual property before the first booking.
Common questions
Do I need a permit to run a short-term rental in Fremont County?
No. Since July 1, 2026, Idaho Code 67-6539(5) bars any county or city from requiring a license, fee, permit, certification, or registration to operate a short-term rental. The county code's printed Class I and Class II transient-use permits predate that change and are not current law.
What counts as a transient rental in the Fremont County code?
The printed definition is rental or occupancy for sleeping or lodging for terms of 30 consecutive days or less, in exchange for a fee or similar consideration. The state statute incorporates the definitions of Idaho Code section 63-1803 for its own purposes.
Can the county still limit how many people stay in my rental?
Only up to the building code's non-transient residential limits. Section 67-6539(3)(d) allows occupancy limits no greater than those the international building codes set for residences - the printed 150-square-feet-per-occupant transient arithmetic is not a requirement the county may enforce.
Is renting to more than 30 people still a commercial use?
Not under state law. Section 67-6539(1) classifies a short-term rental as a non-transient residential use for zoning and building code purposes, displacing the printed code's commercial reclassification of large sleeping counts. Occupancy above the building code's residential limits is the operative ceiling instead.
Does my rental still need a posted local contact?
Not on the building. Requiring internal or external signage, notices or diagrams is on the statute's barred list, 67-6539(2)(a)(x). What survives is the section 3 tenant handout: exits, extinguisher and first-aid locations, and an owner or manager emergency phone number.
Can my subdivision's covenants restrict rentals even without a county permit?
Yes. The statute limits county and city action. Recorded covenants are private restrictions that run with the land, and they can restrict or condition rentals regardless of what the county is allowed to require - read them before listing.
When did Idaho's short-term rental law change?
House Bill 583 passed in the 2026 legislative session with an emergency clause and took effect July 1, 2026. The statute history line records the amendment as 2026, chapter 22 - several months after the county code's most recent consolidation.
What county rules still apply to my rental?
Everything that applies to residences generally: noise, parking, nuisance, curfew and traffic ordinances, preserved by 67-6539(6) - plus, if the county adopts them, the section 3 safety list: smoke alarms, fire extinguisher and carbon monoxide detectors, escape ladders, occupancy within building-code residential limits, and the tenant information handout.
