Does Wyoming Require CO Detectors? Child Care and Local Codes

Last verified: August 24, 2026

Wyoming carbon monoxide detector law in the cited statewide sources is clearest in child care certification rules, which require detectors in all certified child care facilities under Chapter 9 fire standards. The same source set does not provide one broad standalone statewide residential mandate for all private homes rentals and hotels, so broader obligations are generally tied to incorporated model codes and local authority implementation.

Wyoming also uses adoption-by-reference frameworks through fire prevention and electrical safety rule pathways, which can affect occupancy requirements by jurisdiction and code edition. This means owners should identify property type, verify governing authority, and document section-level rationale before applying a detector policy.

Wyoming files should include licensing or code-review evidence and corrective-action records.

Schools and workplaces

Schools: it depends, and the test is one you can apply to the building itself. Wyoming is on the edition that abolished the occupancy list, so the question is no longer what the building is called. The Council on Fire Prevention and Electrical Safety in Buildings incorporated the 2024 International Fire Code and the 2024 International Building Code by reference under W.S. 35-9-106(a). The Department confirms the position operationally rather than only on paper: all new plan review submissions from 28 June 2024 must comply with the 2024 International Fire, Building, Fuel Gas, Mechanical and Existing Building Codes and the 2023 National Electrical Code, and the fire code is incorporated with Appendices D, E, F and G. Re-checked on 2026-08-24 and still the adopted set. Code change F102-21 reorganised Section 915 around the carbon monoxide source rather than around occupancy groups: it removed the references to Group I-1, I-2, I-4, R and Group E classrooms and now requires detection in all occupancies that contain a carbon monoxide source, contain or are supplied with a CO-producing forced-air furnace, have an attached private garage, or have a CO-producing vehicle used within the building. Section 915.1 carries one exception, for Group S, Group F and Group U occupancies that are not normally occupied, and a school is none of those. So a Wyoming school with a gas boiler, a fuel-fired furnace, an attached garage or a vehicle brought inside is covered, and an all-electric one with none of those is outside the trigger rather than exempt. W.S. 35-9-106(a)(i)(B) reaches "all existing buildings" in the statute itself, so the duty does not wait for a permit, and Section 1103.9 carries it to a school already standing. What the school then installs is not what a school in a 2021-edition state installs, and this is where the reorganisation cuts the other way. Group E left the trigger list at Section 915.1.1 and did not leave Section 915: at 915.2.3 the 2024 text reads "a carbon monoxide system that uses carbon monoxide detectors shall be installed in Group E occupancies", with alarm signals from those detectors automatically transmitted to an on-site location staffed by school personnel. A system rather than alarms, which is a different procurement. In the 2021 edition the same section asks only for detectors in classrooms plus the transmission, with an exception where the occupant load is 30 or less; whether the 2024 text keeps that exception was not established here, so a small Wyoming school should confirm it rather than assume it survived.

Workplaces: it depends, and the test is one you can apply to the building itself. The same 2024 reorganisation that answers a Wyoming classroom answers a Wyoming office, and it is why the workplace answer here is not the flat no it is in most states. Code change F102-21 removed the occupancy list from Section 915 and replaced it with a source test: detection is required in all occupancies that contain a carbon monoxide source, contain or are supplied with a CO-producing forced-air furnace, have an attached private garage, or have a CO-producing vehicle used within the building. Section 915.1 then carves out only Group S, Group F and Group U occupancies that are not normally occupied, which is storage, factory and utility space nobody works in. A normally occupied office, shop or workshop with a fuel-burning appliance or an attached garage is inside the requirement. The Council incorporated the 2024 International Fire Code and 2024 International Building Code by reference under W.S. 35-9-106(a) on 28 June 2024 and amended nothing inside them, and W.S. 35-9-106(a)(i)(B) reaches all existing buildings.

When Are CO Alarms Required?

Child care certification fire standards include a statewide detector-installation requirement in cited Chapter 9 provisions.

Where to Install CO Alarms

Cited Chapter 9 child care rule language requires detector installation but does not provide one statewide bedroom-distance matrix in the extracted text.

Device Requirements

Device specifications are not fully detailed in the cited statewide child care rule excerpt.

Landlord and Tenant Responsibilities

Landlord: Wyoming writes no carbon monoxide duty for a landlord and no code-compliance clause either, which makes it the thinnest of the seven. W.S. 1-21-1202(a) requires each owner and agent renting a residential unit to maintain it in a safe and sanitary condition fit for human habitation, with operational electrical, heating and plumbing and hot and cold running water unless both parties agree otherwise in writing. There is no reference to building or housing codes, so a carbon monoxide alarm reaches this section only as part of "safe and sanitary", and the parties may vary the amenity duties by written agreement. Provision: W.S. 1-21-1202.

Responsibility in cited statewide language is tied to certified child care operator compliance rather than a universal landlord-tenant matrix.
The one explicit Wyoming detector requirement written in state rule text belongs to certified child care, at Chapter 9 section 3(b) of the child care certification rules, and a hotel operator is not a certificate holder under it. Lodging is reached instead through the international codes Wyoming adopts by reference, and that pathway was read to its text on 2026-08-05 rather than left open: the Council rules take the 2024 editions whole and amend nothing in them, and W.S. 35-9-106(a)(i) extends the standards past new construction to "the prevention of fire and the protection of life and property from fire and panic in all existing buildings". W.S. 35-9-118(a) lists the exceptions in full, covering farms and ranches of forty acres or more, hospitals and health care facilities, mines and oil field operations, refineries and LPG facilities, railway shops and rolling stock, and utility automotive equipment, and lodging appears nowhere among them.

Enforcement

Enforced by: Two routes, and they answer different buildings. Certified child care runs through Wyoming child care licensing under Chapter 9 of the certification rules. Everything else, lodging included, runs through the State Fire Marshal and the fire code adopted by the Council on Fire Prevention and Electrical Safety in Buildings. W.S. 35-9-121(a) lets a municipality or county take over enforcement, but only where the State Fire Marshal determines it has adopted standards by ordinance or resolution equivalent to or more stringent than the state's, and the delegation is withdrawn if the local body fails to keep pace within six months, so a local programme cannot lower the floor.

Enforcement typically occurs:

During licensing review and fire-standard compliance inspections for certified child care facilities.

What a Tenant Can Do in Wyoming

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

"Via general law" means the Wyoming 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 Wyoming, with the citation or the body of law searched for each.
Rent withholding	NoW.S. 1-21-1204(a)(vi); W.S. 1-21-1206(a). Wyoming nowhere forbids a renter from withholding, and it does not need to. 1-21-1204(a)(vi) makes being current on all payments required by the rental agreement a statutory duty of the renter; 1-21-1203(b) opens the notice route only to a renter who is current; and 1-21-1206(a) then makes the remedies of that section available only to a renter in compliance with all of 1-21-1204 and 1-21-1205. Withholding therefore buys no leverage, it forfeits the article. Nothing elsewhere softens it: escrow and counterclaim appear zero times in the article, deduct appears twice and both are security-deposit deductions, and the single occurrence of withhold is about withholding consent to the owner's entry. Controls on those counts, across roughly 22,000 characters of statutory text: repair appears four times and the phrase current on all payments twice.
Repair and deduct	No provision foundSearched: Wyo. Stat. title 1, chapter 21, article 12, Residential Rental Property, sections 1-21-1201 through 1-21-1211, read in full from the Legislature's Title 1 compilation. The article contains no self-help repair remedy of any kind. What stands in its place is 1-21-1206(c): after two notices the renter sues in circuit court, and the affirmative relief a court may order includes directing the owner to make reasonable repairs. The work still gets done at the owner's expense, but only on an order, and the renter never advances the money. Then read 1-21-1203(d) beside it, because it decides how a repair demand often ends. The owner may refuse to correct and terminate the tenancy instead whenever the cost of repairs exceeds an amount reasonable in light of the rent charged, giving the renter between ten and twenty days to find somewhere else. For an alarm costing less than a tank of fuel that escape is hard for an owner to reach; for the vented appliance behind the alarm it is not.
Right to end the lease	Via general lawW.S. 1-21-1206(c). Judicial rather than self-help. No section lets a Wyoming renter declare the lease over for a defect. What 1-21-1206(c) gives is the power to ask a circuit court for affirmative relief, which may include a declaration terminating the rental agreement; 1-21-1206(d) then refunds the balance of rent and the deposit within thirty days, and the renter vacates no sooner than ten and no later than twenty days after the court's order. Read this cell next to 1-21-1203(d), which hands the same power to the owner on the owner's own decision, as a permitted answer to the renter's repair notice. In this article termination is a remedy the landlord may take and the renter may only request.
Notice the tenant must give	Via general lawW.S. 1-21-1203(b); W.S. 1-21-1206(b). Two notices, and the second carries five required contents. The first, under 1-21-1203(b), needs a renter who is current on all payments and has reasonable cause supported by evidence, and it must describe the condition in writing and specify the remedial action requested. The second, the notice to repair or correct condition, must recite the first, state how many days have elapsed and assert that the period constitutes the reasonable time allowed, list the conditions still uncorrected, demand correction, and state that the renter will seek redress in the courts if the owner does not commence reasonable corrective action within three days. Both must be served by certified mail or in the manner specified by 1-21-1003, so neither may be handed over at the door or emailed. No period runs against the renter before the first notice; the second cannot go out until a reasonable time has passed, and the statute leaves the renter to judge how long that was and then to assert it in writing.
Landlord cure period	Via general law, 3 daysW.S. 1-21-1206(b)(v). Three days, and narrower than it sounds. It is the deadline to commence reasonable corrective action rather than to finish it, and it does not start until the unquantified reasonable time under 1-21-1203(b) has run and the second notice has been served, so the real wait is the unmeasured one in front of it. The owner also has a way to stop the clock without touching the alarm: 1-21-1203(b) offers two permitted responses to the first notice, and the second is to notify the renter in writing that the owner disputes the claim. A dispute sends the renter to circuit court under 1-21-1206(c) with no cure period left to run at all.

Applies to every row above:Wyoming's Residential Rental Property article gives the thinnest tenant position found in this matrix so far, and three features of it combine to produce that. The owner's duties at 1-21-1203(a) are a closed list of four, and the fourth reaches other appliances and facilities only as specifically contracted in the rental agreement. The list contains no duty to comply with building and housing codes at all, which is the crucial difference from Mississippi, North Dakota and South Dakota: a Wyoming municipality that adopts a carbon monoxide requirement does not thereby put one into any landlord's statutory duty, because there is no subdivision for it to enter through. And 1-21-1202(d) allows any duty or obligation in the article to be assigned to a different party or modified by explicit written agreement signed by the parties, so the whole article is waivable in a lease, where South Dakota's equivalent duty says the opposite in terms. That leaves a carbon monoxide alarm one route in, 1-21-1203(a)(i), the requirement not to rent the unit unless it is reasonably safe, sanitary and fit for human occupancy, filtered through 1-21-1202(c), which puts conditions that do not materially affect the physical health or safety of the ordinary renter outside the article entirely. Text was read from a May 2026 Wayback capture of the Legislature's own Title 1 compilation, because wyoleg.gov refuses connections here.

What Wyoming Requires in Lodging

The Wyoming carbon monoxide requirement reaches hotels and short-term rentals.

Hotels already standing: covered too. The Wyoming requirement reaches an existing hotel and not only one being built.

Operator duty: A Wyoming hotel or motel operator takes the duty from the fire code, and the state adopted a recent enough edition for it to bite. The Council on Fire Prevention and Electrical Safety in Buildings incorporates the 2024 International Fire Code and the 2024 International Building Code by reference at Chapter 1 Section 2 of its rules, under W.S. 35-9-106(a), and the State Fire Marshal states the same adoption date of 28 June 2024 on its own fire prevention page. IFC 915.1 sends new buildings to Section 915.1.1 and existing buildings to Section 1103.9, and the triggers in 915.1.1 are a carbon monoxide source in the building, a CO-producing forced-air furnace serving it or sitting in it, an attached private garage, or a CO-producing vehicle used inside. Section 915.2.2 puts the detection in the sleeping units themselves, which for a hotel means the guest rooms. Occupancy is not inferred: IBC 310.2 lists hotels and motels for transient occupancy in Group R-1, and Table 1103.1 marks row 1103.9 as required for R-1. An operator whose building has none of the 915.1.1 conditions, no fuel-burning equipment, no attached garage and no vehicle brought inside, is outside the trigger rather than exempt from the code.

Penalties for Non-Compliance

The cited child care rule set does not provide one stand-alone statewide fine table specific to carbon monoxide detectors.

Noncompliance consequences in cited materials are generally handled through licensing and code-enforcement mechanisms.

Additional Notes

The cited statewide detector requirement is explicit for certified child care facilities.
Residential and lodging obligations arrive through adoption by reference rather than through a Wyoming statute that names a detector, which is why the state looks empty from a statute search and is not. The 2012 departmental filing that circulates adopts the 2006 codes, and the 2006 International Fire Code carries no carbon monoxide provision at all; the operative instrument is the Council's rules, which took the 2024 editions on 28 June 2024.

Local Rules That Differ From State Law

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

Laramie

Laramie borrows the state's technical standard and sells everything around it. Chapter 8.80, the Laramie Rental Housing Code, was enacted by Ordinance 1817 on 20 December 2022, replacing a version that had lasted less than a year, and subsection 8.80.030(G) requires every rental dwelling unit containing a carbon monoxide source to carry at least one approved and functioning alarm. Placement and device specification are handed straight back to the State Fire Marshal's rules and the state building and fire code, so the city writes no standard of its own. What it writes instead is the trigger, the duty and the price. The trigger is unusually wide for a definition that begins with fuel. A carbon monoxide source is any heater, fireplace, appliance or cooking source burning coal, kerosene, petroleum products, wood or other fuel, and also an attached garage with an opening communicating directly with living space. Then the reach: a unit that has none of those is still treated as containing a source if it sits in a structure that has one and is connected to that room by a door, ductwork or a ventilation shaft. A tenant in a gas-free apartment above a boiler room is inside the rule. The duty runs to the owner and is enforced on complaint rather than on inspection. A party to the rental agreement gives the owner written notice, waits ten days, or forty-eight hours where essential services are missing, and then files with the city manager and pays a fee. A valid complaint produces a notice of violation with a ten-day repair deadline, cut to forty-eight hours where the city manager finds an immediate danger or a loss of essential services, and failure to meet it is prosecuted as a criminal information in municipal court. The price is one hundred to seven hundred and fifty dollars for each day the violation continues past the deadline, and the city may additionally revoke the rental registration. The registration is where the evidence sits. Every rental dwelling unit must be registered, renewed every two years, and 8.80.060(H) makes the owner attest that the unit meets 8.80.030, which is the subsection carrying the carbon monoxide duty. The owner must also name an agent living in Wyoming within sixty miles of Laramie to receive notices. One limit matters for anyone letting short-term. The chapter's definition of rental housing excludes occupancy in transient lodging, which it defines as a house, room or suite occupied as other than a principal residence for periods under thirty consecutive days. Laramie's carbon monoxide duty therefore stops at the door of the short let, along with nine other carve-outs covering hospitals, licensed care, institutional and student housing, pre-closing and post-closing occupancy, fraternal buildings, squatters, employee housing, owner-occupied condominiums and agricultural lettings.

Laramie Municipal Code Chapter 8.80, Laramie Rental Housing Code, Section 8.80.030(G) with definitions at 8.80.020, enforcement at 8.80.040, penalties at 8.80.050 and registration at 8.80.060 (Ord. No. 1817, 12-20-2022; code codified through Ord. No. 1875, 18 November 2025) Checked 2026-08-11.

Cody

Cody turns the alarm into a licence condition for one building type, and puts a rotating inspection behind it. A bed and breakfast inn cannot open until it passes a fire and life safety inspection, and item (c) of that inspection is carbon monoxide alarms where required by code and operable, sitting between working smoke detectors and a posted four-inch address number in a nine-item list that also covers a 2A:10BC extinguisher, access to the electrical panel, clearance around heat sources, dryer vent obstruction, bedroom escape openings measured against IRC R310.1 to R310.4, and emergency contact numbers posted for the manager and 911. The cadence is the part with no counterpart elsewhere in this survey. The inspection happens at least annually, but who performs it alternates: the city reinspects on any change of ownership and on every third year after the first inspection, and in the intervening years the owner or manager performs it. Registration is annual by 1 May, carries an application fee and a late fee, and produces a certificate the inn has to post, which expires at the end of the following 1 May. Guest occupancy is capped at ten people, above which the property is zoned as a hotel, and no individual guest may stay 120 consecutive days or 120 days in a year. The wording "where required by code" means Cody adds no standard the state fire code does not already set. What it adds is the checking, and the fact that failing it costs the inn its authorisation to operate. The provision is printed twice, at 10-8-2(B) for residential zoning districts and at 10-11-2(B) for commercial and industrial ones, in identical terms, so the obligation follows the use rather than the zone. It reaches bed and breakfast inns only; the code's seven short-term rental references carry no detector condition.

Cody City Code Sections 10-8-2(B) and 10-11-2(B), supplemental development standards for bed and breakfast inns, subsection 6(c) with the inspection cadence at subsection 7 and registration at subsection 13 (2025 S-12) Checked 2026-08-11.

What was checked:Wyoming leaves room for a local rule and two towns have used it, in opposite ways. The state fire code is administered centrally, and W.S. 35-9-121 hands enforcement to a municipality or county only where the State Fire Marshal has found that its ordinances meet or beat the state standards, with authority reverting to the department if the locality falls behind. That makes the state a floor rather than a ceiling. The section could not be re-read from a primary source on 2026-08-11: wyoleg.gov refused connections, and Justia and FindLaw both answered 403. The reading above is this site's own record from 2026-08-05 and is labelled as restated rather than re-verified. Twelve municipalities were searched on 2026-08-11: Jackson, Cheyenne, Casper, Laramie, Cody, Sheridan, Rock Springs, Green River, Douglas, Powell, Rawlins and Star Valley Ranch. Three more, Afton, Alpine and Lander, answered zero for every control including "building" and "fire", which is the publisher-record-with-no-published-edition shape this survey has now met eight times, and they are not counted clean. Two results are worth naming. Jackson is the state's short-term rental market and it carries no detector rule at all: Chapter 5.60, its residential short-term rental permit chapter, was repealed by Ordinance 1357 in 2023 and short lets are now a zoning use under Land Development Regulations 6.1.5.C, where the conditions are density, parking and workforce housing. Its amendments to the 2024 International Fire Code run to sprinklers, water supply distance and day care occupancy and leave Section 915 alone. Star Valley Ranch answers nineteen times for short-term rentals and never for carbon monoxide. Casper is the one city here that must not be read as clean, and the reason is a gap in the published code rather than an empty one. Section 15.02.060 amends IRC Section R202 to add a definition of "Collateral Damage", meaning the slotting of drywall or destruction of finishes needed to run wiring for hardwired smoke or carbon monoxide detectors. Nothing in the published code ever uses the term again. The chapter runs 15.02.010 to 15.02.170 by its own editor's note and the code comparative table maps Ordinance 17-24 sections 3 to 8 onto 15.02.050 through 15.02.100, but both the chapter body and the publisher's own table of contents skip 15.02.090 and 15.02.100. Those two numbers fall between the R302 amendments and the R702 amendment, which is where the smoke alarm and carbon monoxide sections sit in the model code, so the missing sections are the likeliest amendments the definition was written for. That is an inference from the numbering, not a reading, and the text was not obtainable: casperwy.gov answers 403. Getting the model numbers right here matters and depends entirely on the edition. Section 15.02.020 adopts the 2024 International Residential Code, and the 2024 edition reordered Chapter 3: smoke alarms are Section R310 and carbon monoxide alarms are Section R311. Under the 2018 and 2021 editions the same two subjects were R314 and R315, which is what nearly all published guidance still cites. In the edition Casper adopted, R314 is mezzanines and R315 is sleeping lofts, so anyone looking for Casper's carbon monoxide amendment at R315 would land on a real section about something else with nothing to signal the mistake.

The article the entire remedy row on this page argues from, and until 2026-08-20 it appeared in no source entry. Read from FindLaw because wyoleg.gov does not answer this network. The closed-list finding checks out and it is worth having verbatim, because the whole argument rests on what is absent. 1-21-1203(a) is four subdivisions and no more: do not rent a unit unless it is "reasonably safe, sanitary and fit for human occupancy"; maintain common areas; "maintain electrical systems, plumbing, heating and hot and cold water"; and maintain other appliances and facilities "as specifically contracted in the rental agreement". There is no subdivision requiring compliance with building or housing codes at all, which is what stops a Wyoming municipal carbon monoxide ordinance from entering any landlord duty. One consequence follows that the closed list does not remove. A hardwired alarm is part of the electrical system, so subdivision (iii) reaches a hardwired unit already installed even though no subdivision requires one to be installed. A plug-in alarm is not, unless the rental agreement contracted for it under subdivision (iv). 1-21-1206(b) confirms the five contents of the second notice, including that it must state that the renter will seek redress in the courts if the owner fails to commence reasonable corrective action within three days, and 1-21-1206(a) confirms the compliance gate.

Frequently Asked Questions

What is the clearest statewide Wyoming CO detector requirement in cited sources?

The clearest explicit statewide requirement in the cited Wyoming materials is in child care certification fire standards, where detectors are required in all certified child care facilities. This is a concrete rule for that regulated setting, not a blanket requirement for every private home and rental. Operators should classify property type first and avoid assuming that one child care rule automatically governs all occupancies. Wyoming compliance files should store chapter and section citations with inspection records.

Does Wyoming have one universal residential CO alarm statute in these sources?

In the sources cited here, Wyoming does not show one single standalone statute that mandates carbon monoxide alarms in every private home rental and hotel statewide. Broader duties are more likely to arise through incorporated model codes and local authority implementation. Teams should verify jurisdiction, occupancy class, and adopted edition before finalizing policy language. Wyoming records should include written scope determinations and the exact source used. Keep this determination in writing before publishing occupancy policies.

How should Wyoming operators handle occupancy scope uncertainty?

When scope is uncertain, the safest approach is to map each property against the applicable licensing rule or adopted code pathway, then request clarification from the authority having jurisdiction. This is important in Wyoming because adoption-by-reference frameworks can create differences by occupancy and enforcement context. Operators should keep written interpretations, decision dates, and reviewer identity in the compliance file. That documentation helps during audits, inspections, and dispute resolution.

What penalty table is listed in cited Wyoming detector rules?

The cited Wyoming child care and adoption-reference sources do not provide one stand-alone statewide fine table dedicated only to carbon monoxide detector violations. Compliance consequences are generally handled through licensing and enforcement mechanisms in the relevant program. Teams should therefore treat correction deadlines and documentation quality as high priority controls. Wyoming notices should cite the governing chapter or rule section for each corrective action. Track notice date, correction date, and verification result in one log.

Before exempting an all-electric Wyoming unit, what documentation should owners collect?

Not automatically. Because broad private-home obligations are not expressed as one universal statewide statute, exemption decisions should be tied to the locally applicable adopted code or licensing pathway. Owners should avoid generic assumptions based only on utility type and seek local interpretation where scope is unclear. Wyoming files should include written exemption rationale, approving authority, and review date. Reconfirm exemption logic after renovations or occupancy changes. Store the final decision with the maintenance record set.

What is the key policy contrast between Wyoming child-care rules and Montana rental statutes?

Wyoming emphasizes targeted statewide child care language, in the certified child care rules at Chapter 9, plus adoption-by-reference frameworks, while Montana operators can face a different statewide and local mix by occupancy. Regional teams should keep separate Mountain state matrices rather than one shared template. For side-by-side planning, review Montana CO detector laws and compare scope, enforcement channels, and documentation requirements. Store cross-state comparisons in onboarding guides for regional managers and field supervisors.
