What Idaho Requires for CO Detectors: Permits, Placement, Penalties

Last verified: August 24, 2026

Idaho carbon monoxide detector laws for residential settings are mainly tied to Idaho Administrative Code IDAPA 24.39.70, including language that references IRC M1203.1 in permit-driven scenarios. In practical terms, the clearest statewide trigger appears when covered fuel-burning conditions exist and work requiring permits moves a dwelling into active code review.

Idaho also includes a civil-penalty pathway up to $1,000 per offense under the same rule chapter, so noncompliance is not only a technical issue but also an enforcement risk. Owners and contractors should document trigger conditions, placement near sleeping areas, and final inspection results in the project file.

Because Idaho's rental statutes are less explicit on broad CO allocation than smoke-detector language, operators should combine code compliance records with local enforcement guidance and lease-level maintenance procedures.

Schools and workplaces

Schools: it depends, and the test is one you can apply to the building itself. Two tests, and the second is the same one that decides an Idaho hotel. Section 915 as adopted reaches Group E classrooms where a condition in Sections 915.1.2 to 915.1.6 exists, so a classroom is covered where it holds a fuel-burning appliance or fireplace, is served by a fuel-burning forced-air furnace, sits in a building holding such equipment with a communicating opening, or adjoins an attached private garage. A school built since the fire code took effect on 1 July 2024 is covered outright on those conditions, in every county. Where it is covered, the signal has somewhere to go: Section 915.2.3 requires the classroom's alarm signals to be "automatically transmitted to an on-site location that is staffed by school personnel", excepting a Group E occupancy with an occupant load of 30 or less. That limb belongs on an Idaho page more than on most, because Idaho declines to name an edition at all. IDAPA 18.08.01 delegates to Idaho Code 67-5229 and asserts no year, so nothing here can say which International Fire Code cycle a district enforces. Section 915.2.3 is in every cycle that carries Section 915, from 2015 onward, which makes it one of the few things about an Idaho classroom the missing edition leaves settled. What the edition would change is the class of device, since the 2024 text asks for a supervised system in place of alarms. A school already standing is not, because IDAPA 18.08.01.010 deletes item 3 from IFC 102.1 and section 030 qualifies IFC 1101.1, so Section 1103.9 never arrives on its own and what remains is IFC 102.1 item 4, an existing condition the fire code official judges a distinct hazard to life or property. Ask the fire chief for the district, or the county sheriff where no fire department covers the area.

Workplaces: Idaho places no carbon monoxide detection duty on an office, shop or other workplace. Federal and state occupational rules set an exposure limit for carbon monoxide in air; they do not require a detector to be installed, and this row is about installation. Section 915.1.1 as adopted by IDAPA 18.08.01 reaches Group I-1, I-2, I-4 and R occupancies and Group E classrooms, and names no Group B, F, M or S, so an Idaho office or shop is outside the fire code's carbon monoxide provision. Idaho has no statute placing a carbon monoxide duty on a workplace, and Idaho Code 67-6539(3) is a ceiling on what a city may require of short-term rentals rather than a duty of any kind.

When Are CO Alarms Required?

Buildings with fuel-burning appliances
When building permits are required
Existing dwellings enter the clearest statewide CO alarm pathway when permit-triggered work applies under IDAPA 24.39.70 and related IRC M1203.1 language.

Where to Install CO Alarms

Outside each separate sleeping area in the immediate vicinity of bedrooms (IRC M1203.1 path used in IDAPA 24.39.70 context).

Device Requirements

Approved carbon monoxide alarm consistent with the adopted code pathway.

Landlord and Tenant Responsibilities

Landlord: Idaho has no landlord-tenant act and no carbon monoxide duty for a landlord. What a tenant can reach is Idaho Code 6-320(a)(3), maintaining the premises in a manner hazardous to the health or safety of the tenant, which is a general ground and not a device rule. The point worth knowing is what sits beside it: 6-320(a)(6) is a full install-and-deduct right and it is written for approved smoke detectors, defined by their ability to detect particles of combustion, with nothing about carbon monoxide. A tenant who finds the self-help right in this section will reasonably think it covers the alarm they have a problem with, and it does not. Provision: Idaho Code 6-320(a)(3).

Tenant: Idaho puts no carbon monoxide duty on a tenant. The only device duty in 6-320 is at (a)(6), where the tenant "shall maintain the smoke detectors in good working order during the tenant's rental period", and that subsection defines an approved detector by its ability to detect particles of combustion. Carbon monoxide is outside it, on both sides of the landlord and tenant split. Read for this answer: Idaho Code 6-320(a), grounds (1) through (6) in full, read for a carbon monoxide duty on a tenant.

IDAPA 24.39.70 addresses code compliance and inspections; the cited Idaho sources do not establish a full statewide landlord-tenant CO duty matrix.

Enforcement

Enforced by: Idaho Division of Occupational and Professional Licenses and local inspection authorities through permit and code-enforcement workflow.

Enforcement typically occurs:

During permit review and field inspections under IDAPA 24.39.70.
During enforcement actions where code violations are identified.

What a Tenant Can Do in Idaho

When a carbon monoxide alarm stops working in a rented home in Idaho, these are the five routes a tenant can take and where each one comes from.

"Via general law" means the Idaho carbon monoxide statute itself is silent and the remedy comes from the state's landlord-tenant law instead. The remedy is available even though the alarm rule does not contain it.

"No provision found" is a finding rather than a gap in the research: the chapter that would carry that remedy was read and contains nothing either way. What was read is named beside the row.

Tenant remedies for a defective carbon monoxide alarm in Idaho, with the citation or the body of law searched for each.
Rent withholding	No provision foundSearched: Idaho Code 6-320, subsections (a) through (e) in full, the tenant's action for damages and specific performance in Title 6, chapter 3. The section's remedies are a money judgment and an order compelling performance, and it contains nothing that lets a tenant hold back rent or pay it into court. Nor does it forbid withholding, so this is silence rather than a bar of the North Carolina or Alabama kind. What Idaho substitutes is speed: an action brought only for specific performance must be tried within twelve days of the complaint, with service no less than five days before trial.
Repair and deduct	No provision foundSearched: Idaho Code 6-320, subsections (a) through (e), including the enumerated grounds at (a)(1) through (a)(6). Idaho does have an install-and-deduct right and it is for the wrong device. Ground (a)(6) lets a tenant whose landlord has not installed working smoke detectors serve certified mail, return receipt requested, and install them and deduct the cost from next month's rent if the landlord does not act within 72 hours. That provision names approved smoke detectors, defines them by their ability to detect particles of combustion, and says nothing about carbon monoxide alarms, so the one deduction Idaho grants does not reach the device this matrix is about. No general repair-and-deduct sits behind it.
Right to end the lease	No provision foundSearched: Idaho Code 6-320, subsections (a) through (e), read for any provision letting a tenant end the tenancy over the condition of the premises. Subsection (c) sets out what a successful tenant gets: judgment for the damages assessed, specific performance for any breach shown by the evidence, and costs. Ending the tenancy is not among them, and no other part of the section offers it. A tenant who wants out of an Idaho lease over a defect is left with common-law constructive eviction.
Notice the tenant must give	Via general law, 3 daysIdaho Code 6-320(d). Three days' written notice is a standing requirement rather than a courtesy: the tenant must list each failure or breach the action will rest on and demand performance or cure, and only once three days have passed without cure may the action be commenced. A notice that omits a ground cannot support a claim on it, so the letter defines the case.
Landlord cure period	Via general law, 3 daysIdaho Code 6-320(d). The same three days, seen from the landlord's side, and the shortest general cure period in the fifty-one, shared with Utah and Wyoming. It is untiered, so a live carbon monoxide hazard and an unreturned security deposit run the same seventy-two hours. The separate 72 hours in ground (a)(6) is a different clock attached to smoke detectors and should not be read as applying here.

Applies to every row above:Idaho has no landlord-tenant act. Its tenant remedy is a single litigation section, 6-320, filed in Title 6 among actions in particular cases, so the positional rule that locates a counterclaim in a URLTA state has nothing to work on here. The section lists six grounds for suing and gives two remedies, damages and specific performance, and one narrow self-help right. The common description of Idaho as a state allowing neither rent withholding nor repair-and-deduct is accurate about self-help for a carbon monoxide problem and misleading about everything else: 6-320 does supply a remedy, and where the tenant sues only for specific performance the court must set trial within twelve days of filing. No other remedy row in the fifty-one carries a statutory deadline for the hearing itself. Two limits govern the row. The section does not reach tracts of five acres or more used for agriculture, and the text here was read from an archived capture of the Legislature's site dated 26 November 2020, because legislature.idaho.gov does not answer automated requests. Confirm any figure against the current code before relying on it.

What Idaho Requires in Lodging

The Idaho requirement reaches some lodging and not the rest, and which side a property falls on is something an operator can check rather than guess.

What it turns on for a hotel:Coverage turns on when the building was finished, and it holds in every county. Idaho Code 41-253(1) adopts the International Fire Code as the minimum standards for the state and IDAPA 18.08.01 carries the adoption with Section 915 unamended, so a hotel built since the fire code took effect is covered outright through IFC 102.1 item 1, with no local election anywhere in the chain. A hotel that predates the code is reached only where the fire code official considers it a distinct hazard to life or property under IFC 102.1 item 4, because IDAPA 18.08.01.010 deletes item 3 of that section and section 030 qualifies IFC 1101.1, which together stop Section 1103.9 arriving on its own. Idaho Code 39-4116 makes the building permit programme elective, but that election decides who reviews plans, and the requirement exists either way.

What it turns on for a short-term rental:Two separate tests decide it, and a host has to clear both. The first is the fire code and the building's age, exactly as for a hotel: Idaho Code 41-253(1) adopts the International Fire Code as the minimum standards for the state and IDAPA 18.08.01 carries the adoption with Section 915 unamended, so a property built since the fire code took effect is covered outright through IFC 102.1 item 1, while one that predates it is reached only where the fire code official considers it a distinct hazard to life or property under IFC 102.1 item 4, because IDAPA 18.08.01.010 deletes item 3 of that section and section 030 qualifies IFC 1101.1. The second test does not apply to hotels at all. Idaho Code 67-6539(3), as amended by House Bill 583 with effect from 1 July 2026, lets a county or city require by ordinance that a short-term rental carry a working carbon monoxide detector on each floor, alongside a fire extinguisher per floor, smoke alarms in all sleeping areas, escape ladders in sleeping areas above the ground floor and a posted emergency handout. That subsection is a ceiling on local power rather than a state duty: it opens "may, by ordinance, require" and closes the list with "only", so absent a local ordinance it requires nothing, and a host should ask their city or county whether one exists. Two limits in the same section are worth knowing: 67-6539(2)(a)(ix) makes requiring an inspection a prohibited restriction, so a city may require the detector and may not require an inspection to confirm it, and 67-6539(5) bars any licence, fee, permit, certification or registration to operate a short-term rental. A short-term rental is defined at Idaho Code 63-1803(4) as a single-family house, dwelling unit, condominium, cooperative, timeshare unit or owner-occupied home let for a fee for thirty days or less, which is why none of this reaches a hotel.

Hotels already standing: it depends, and on a separate test from the one that decides coverage generally. An existing Idaho hotel is reached only if the fire code official says so. IDAPA 18.08.01.010 deletes Item No. 3 from IFC 102.1, which is the hook that applies Chapter 11 to existing buildings, and section 030 then adds to IFC 1101.1 the words "only, if in the opinion of the fire code official, they constitute a distinct hazard to life or property". Two removals of the same route, so Section 1103.9 never arrives on its own. What is left is IFC 102.1 item 4, which reaches existing conditions that in the fire code official's opinion constitute a distinct hazard. Ask the local fire chief, or the county sheriff where no fire department exists, since Idaho Code 41-256(1) makes both assistants to the state fire marshal. A hotel built since the fire code took effect is covered outright and does not depend on this test.

Operator duty: No Idaho statute names lodging, so a hotel operator's duty comes from the state fire code, which reaches the property wherever it stands. Idaho Code 41-253(1) adopts the International Fire Code as the minimum standards for Idaho and IDAPA 18.08.01 carries that adoption, leaving Section 915, the carbon monoxide provision, unamended. A hotel is a Group R-1 occupancy, so Section 915 asks for detection in sleeping units that contain a fuel-burning appliance, are served by a fuel-burning forced-air furnace, sit in a building holding fuel-burning appliances, or adjoin an attached private garage. For a hotel built since the code took effect that duty runs in every county, with the local fire chief, or the county sheriff where no fire department exists, carrying it out as an assistant to the State Fire Marshal under Idaho Code 41-256(1). For a hotel that predates the code, IDAPA 18.08.01.010 and section 030 remove the automatic route into Chapter 11, and the duty arrives only where the fire code official judges the building a distinct hazard to life or property. The building code adds a second route where a local government has elected to run a permit programme under Idaho Code 39-4116, applying the same Section 915 through the 2018 IBC edition that IDAPA 24.39.30.600.01 fixes.

Local Rules That Differ From State Law

At least one Idaho municipality sets CO requirements that go beyond the statewide rule. Where your property sits decides which applies, and the stricter one governs.

Ketchum

Ketchum requires the detector by floor and narrows the statute's menu rather than widening it. Section 5.09.040 sets the standards a short-term rental must meet, and item 3 provides that a carbon monoxide detector is required on each floor if there is a garage, a solid fuel appliance or a gas appliance, and as otherwise required in an approved fire safety plan. Idaho Code 67-6539(3)(b) permits a city to require a detector on each floor without qualification, so Ketchum has asked for less than it could: a house with no garage and nothing burning in it owes nothing here. Item 2 handles smoke alarms by manufacturer's specification and the same fire safety plan. Two things to check before relying on it. The trailing words "as otherwise required in an approved fire safety plan" let the plan reach further than the ordinance text, which is where a Ketchum operator will find out what is actually expected. And the whole of Chapter 5.09 is a short-term rental permit scheme, sitting in the business licences and regulations title, which is the arrangement Idaho Code 67-6539(5) now addresses.

Ketchum Municipal Code Section 5.09.040(3), short-term rental permit standards, codified through Ordinance No. 1260 (17 November 2025) Checked 2026-08-11.

Driggs

Driggs takes the same approach in plainer words and without the fire safety plan escape hatch. Section 3-5-4 sets the standards for short-term rental dwelling units, and item 4 provides that a carbon monoxide detector is required on each floor if there is a garage, solid fuel appliance or gas appliance. Item 3 carries a smoke alarm rule with a detail worth noting for a split-level house: an alarm on the upper level suffices for the adjacent lower level provided the lower level is less than one full storey below. As with Ketchum, the trigger narrows what Idaho Code 67-6539(3)(b) would have allowed, and the section sits inside a standards-and-permit chapter codified in October 2025, before the statute reached its current form.

Driggs City Code Section 3-5-4(4), standards for short-term rental dwelling units, codified through Ordinance No. 485-24 (21 October 2025) Checked 2026-08-11.

What was checked:Idaho is the state that most nearly inverts what this field was built to record, and for short lets it inverts it completely. Idaho Code 67-6539(3) opens "A county or city may, by ordinance, require an owner of a short-term rental to implement the following requirements only", and paragraph (b) of that list is a functioning fire extinguisher and a functioning carbon monoxide detector on each floor. Read the two words that matter: "may" and "only". Absent a local ordinance the section requires nothing at all, and where an ordinance exists the state has already fixed the outer edge of what it may demand. So the local rule is not an overlay on a state duty; for a short-term rental it is the whole duty, and the state's role is to cap it. Two further limits make Idaho unlike every other state in this survey. Section 67-6539(2)(a)(ix) makes requiring an inspection a prohibited restriction, so a city may require the detector and may not send anyone to confirm it. Section 67-6539(5) bars any licence, fee, permit, certification or registration to operate a short-term rental. Almost every local rule this survey has found elsewhere hangs on exactly those two hooks, an inspection or a licence, and Idaho has removed both. That timing needs stating plainly, because it bears on both entries below. House Bill 583, which put subsections (3) and (5) in their current form, was signed on 16 March 2026 with an emergency clause and took effect on 1 July 2026. Ketchum's code as published is codified through Ordinance 1260 of 17 November 2025, and Driggs's through Ordinance 485-24 of 21 October 2025. Both are therefore a picture of late 2025, both still frame their carbon monoxide standard inside a permit scheme, and whether either city has amended since the statute took effect is not visible in the codified text. Anyone relying on either should ask the city what survives. Four municipalities read on 2026-08-11: Ketchum, Sandpoint, Driggs and Victor. Sandpoint carries nothing on carbon monoxide, control-tested against an index answering 158 times for "building" and 13 for "short-term rental". Victor could not be read at all and must not be counted clean: its publisher record holds no code product, only a MuniDocs product with no published edition behind it, so every search returns zero. Boise, Coeur d'Alene, McCall, Sun Valley, Hailey and Sandpoint's Lake Pend Oreille neighbours were not searched, and Boise and Coeur d'Alene are the two that would matter most.

Frequently Asked Questions

When does Idaho law clearly require carbon monoxide alarms in homes?

Idaho's clearest statewide trigger appears in IDAPA 24.39.70 when covered permit-based work and fuel-burning conditions bring a dwelling into code review under the IRC M1203.1 pathway. That means many obligations are enforced during project activity rather than only at routine occupancy. Owners should treat permit intake, inspection scheduling, and final signoff as compliance control points. Maintaining installation records and inspection notes is important if compliance is later challenged. In Idaho, include IDAPA 24.39.70 references in permit submittals and inspection records.

Are Idaho CO alarm obligations universal for all existing residences?

Not in one simple statewide sentence. Idaho sources point most clearly to permit-triggered pathways and fuel-related risk conditions under IDAPA 24.39.70, so obligations can depend on project status and local enforcement practice. Existing homes without active permit pathways may still face local expectations, but operators should verify that directly with the authority having jurisdiction. This avoids over- or under-compliance caused by assumptions from another city or county. Idaho DOPL and local inspector comments should be documented before exemption decisions are finalized.

How is Idaho CO detector enforcement handled when penalty language is limited?

IDAPA 24.39.70.300 allows civil penalties up to $1,000 per separate offense, which creates a meaningful enforcement risk when violations are documented. In addition to direct penalties, unresolved detector issues can delay permit closeout and increase post-incident liability. Contractors and owners should correct deficiencies quickly and preserve dated proof of remediation. In compliance communications, cite the specific IDAPA section and inspection record so actions are defensible. Idaho authorities can escalate findings when repeated noncompliance appears in inspection history.

In Idaho, what evidence is needed before marking an all-electric home exempt?

Not automatically. While fuel-burning conditions are central to many code triggers, all-electric labeling alone is not a complete legal analysis in multifamily or mixed-use settings. Attached spaces, neighboring combustion sources, or local code interpretation can still influence expectations. Idaho operators should confirm actual conditions and local enforcement guidance before deciding a unit is outside alarm obligations, and document that decision in writing. In Idaho, cite IDAPA 24.39.70 and local AHJ comments when granting any exemption.

How should Idaho landlords handle CO compliance when statutes focus on smoke detectors?

Idaho Statutes Sec. 6-320 gives explicit smoke-detector duties, but statewide CO allocation is less direct in the cited statute language. Landlords should therefore combine lease terms, maintenance workflows, and local code-enforcement requirements under IDAPA pathways instead of relying on one statute line. A practical approach is move-in verification, repair ticket logs, and written tenant reporting procedures. This creates stronger evidence if disputes or inspections occur. Idaho landlords should reference Sec. 6-320 and IDAPA 24.39.70 in written policies and vendor instructions.

How do Idaho requirements compare with Montana approaches?

Idaho compliance is heavily tied to permit and code-enforcement pathways in IDAPA 24.39.70, while Montana operators often face a different mix of code adoption and local implementation details. Regional teams should avoid one shared checklist and map each state triggers, occupancy scope, and enforcement channels separately. For nearby-state benchmarking before finalizing Mountain West SOPs, review Montana CO detector laws. Idaho teams should preserve IDAPA citations when comparing Montana procedures.
