CO Detector Rules in Colorado: Sale, Permit, and Source Triggers

Last verified: August 24, 2026

Colorado carbon monoxide detector laws span five sections, C.R.S. 38-45-102 through 38-45-106, while placement rules follow code language tied to IRC R315. Covered single-family homes and many rentals can trigger obligations during sale, permit-based work, and occupancy scenarios involving fuel-burning appliances or attached garages.

The statute also sets landlord and tenant maintenance expectations, so compliance is operational as well as construction-related. Property managers should track move-in readiness, written defect notices, and correction timelines to reduce enforcement and liability risk.

Because Colorado combines statute text with code pathways, the most reliable approach is to map trigger event, occupancy type, and local inspection process before project start and lease turnover. For multi-jurisdiction portfolios, Colorado files should pair statutory citations with local code-adoption proof to prevent transfer delays and inspection disputes.

Schools and workplaces

Schools: it depends, and the test is one you can apply to the building itself. Colorado's fire code applies to schools and to almost nothing else, which is the reverse of the usual shape. 8 CCR 1507-101 adopts the 2021 International Fire Code only for property under the oversight of the Division of Fire Prevention and Control, and CRS 24-33.5-1203(1)(p) and (p.5) confine that oversight to public school and local district college buildings and to health facilities. So the instrument that cannot reach a Colorado hotel reaches a Colorado school directly. Within it, Section 915.1.1 covers classrooms in Group E occupancies where a condition in Sections 915.1.2 through 915.1.6 exists, and Section 1103.9 carries the same conditions to a school already standing. Note that the oversight names local district college buildings as well, so Colorado reaches further than the Group E line does: post-secondary teaching space is Group B under the model code and is inside the Division's remit here. That distinction decides who has to be able to hear the alarm, not just who has to own one. Under Section 915.2.3 a Group E classroom takes a detector and a route for its signal: the alarm signals go "automatically transmitted to an on-site location that is staffed by school personnel", unless the Group E occupancy has an occupant load of 30 or less. Duty and exception are both keyed to Group E, so a Colorado public school with a fuel-burning source owes a monitored path to a staffed office and a local district college building in the same Division remit owes nothing under this section at all, because Group B is outside it. Being inside the Division's oversight and being inside Section 915 are two different questions here.

Workplaces: Colorado 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. Two instruments and neither reaches an office. CRS Article 45, sections 38-45-102 through 38-45-106, is Colorado's standalone carbon monoxide statute and it is written around a single-family dwelling and a dwelling unit in a multi-family dwelling; it never reaches a non-residential occupancy. The fire code cannot supply one either, because 8 CCR 1507-101 adopts the 2021 International Fire Code only for property under the Division of Fire Prevention and Control's oversight, and CRS 24-33.5-1203(1)(p) and (p.5) confine that oversight to public school and local district college buildings and to health facilities. A Colorado workplace is outside both.

Where to Install CO Alarms

For new construction: CO alarm installed outside of each separate sleeping area within 15 feet of the entrance to the bedrooms in dwelling units with fuel-fired appliances and in dwelling units with attached garages (Code of Colorado Regulations, ruleVersionId=4951, Section R315).

Landlord and Tenant Responsibilities

Landlord: Replace CO alarm stolen/removed/missing/non-operational before new tenant moves in. Provide batteries at move-in. Replace alarms when notified by tenant. Fix deficiencies when notified. NOT responsible for day-to-day maintenance/battery replacement (§38-45-104(3)). Provision: §38-45-104(3).

Tenant: Keep, test, and maintain all CO alarms in good repair. Notify owner in writing if batteries need replacement, alarm is stolen/removed/missing/non-operational, or any deficiency tenant cannot correct (§38-45-104(4)). Provision: §38-45-104(4).

No operator duty is recorded for hotels or short-term rentals because Article 45 does not reach them. The statute names its covered buildings one by one, single-family dwellings at C.R.S. 38-45-102 and rental property at 38-45-104, and lodging appears in none of the six sections from 38-45-101 to 38-45-106. The silence here is a finding rather than a gap.

Enforcement

Enforced by: No single designated enforcement authority. Colorado Real Estate Commission (§12-10-206) enforces disclosure in listings. Local building departments enforce permit-triggered requirements. Local governments may adopt stricter codes per §38-45-105.

What a Tenant Can Do in Colorado

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

"Via general law" means the Colorado 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 Colorado, with the citation or the body of law searched for each.
Rent withholding	No provision foundSearched: C.R.S. Title 38, Article 12, Part 5 (Warranty of Habitability), sections 38-12-501 through 38-12-511, together with Article 45 (Carbon Monoxide Alarms), sections 38-45-101 to 38-45-106. Part 5 hands the tenant deduction, termination, damages and injunctive relief, and stops there. No escrow account, no procedure for paying rent into court, and no provision either granting or barring a withholding. Colorado put its weight behind self-help repair instead, which is the opposite trade from Washington and Maryland, where the money goes to a third party and the tenant keeps the tenancy.
Repair and deduct	Via general lawC.R.S. 38-12-507. One of five uncapped repair-and-deduct remedies in the fifty-one, with Louisiana, North Dakota, Oregon and South Dakota. Virginia stops at the greater of one month's rent or $1,500 and Arizona at the greater of $300 or half a month, while Colorado names no ceiling at all. The controls are procedural instead: ten days' written notice, or 48 hours where the condition is a health or safety emergency, a qualified professional doing the work, and documentation to the landlord. A tenant spreading the deduction across two or more rental periods gives one notice rather than one per period.
Right to end the lease	Via general lawC.R.S. 38-12-507. Termination carries no liability or financial penalty to the tenant where the condition stays unremedied, on a written notice the section sets at between 10 and 60 days. A condition that recurs within six months of being fixed opens a second route, terminating on 30 days' notice, which matters for an intermittent fault more than for a dead device.
Notice the tenant must give	Yes, in the CO ruleC.R.S. 38-45-104. The carbon monoxide statute itself makes tenant notice the trigger: the owner of rental property must replace any alarm when notified by a tenant of deficiencies, on top of replacing alarms found missing or inoperative after a previous occupancy and providing batteries at move-in. No form and no waiting period attach. The separate notices under 38-12-507 are what start the deduction and termination clocks, and they are not the same notice.
Landlord cure period	No provision foundSearched: C.R.S. Article 45 (Carbon Monoxide Alarms), sections 38-45-101 to 38-45-106, and C.R.S. Title 38, Article 12, Part 5, sections 38-12-501 through 38-12-511. 38-45-104 requires replacement once a tenant reports a deficiency and fixes no period for it. Part 5 does carry deadlines, 24 hours where a condition materially interferes with life, health or safety and 72 hours otherwise, but those run from a breach of the warranty of habitability, and 38-12-505 does not enumerate carbon monoxide alarms among the conditions that make a premises uninhabitable. Whether a dead alarm reaches Part 5 through some other route is an argument a tenant would have to win, so no number is recorded here.

Applies to every row above:Colorado is not a URLTA state; its remedies live in the warranty of habitability at Article 12, Part 5, which the legislature rewrote in 2019 and which owes nothing to the model act's structure. The row turns on a seam between two statutes that were written separately. Article 45 gives the carbon monoxide duty and ties it to tenant notice, but attaches no deadline to it. The habitability machinery in Part 5 is where all the deadlines are, and the list of conditions that make a premises uninhabitable at 38-12-505 does not name carbon monoxide alarms. So the statute that mentions alarms has no clock, and the statute with the clocks does not mention alarms. A Colorado tenant with a dead alarm has a duty they can point to and no date they can count to.

What Colorado Requires in Lodging

The Colorado 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 whether the area around the property has building standards of its own. Colorado's fire code does not reach lodging: 8 CCR 1507-101 adopts the 2021 International Fire Code only for property under the oversight of the Division of Fire Prevention and Control, and CRS 24-33.5-1203(1)(p) and (p.5) confine that oversight to public school and local district college buildings and to health facilities. The instrument that does reach a hotel is the State Housing Board's, at 8 CCR 1302-14, which adopts the 2021 International Building Code for site-built hotels, motels and multi-family structures in those areas of the state where no standards exist, and the Division of Housing issues the certificate of occupancy for them. Where the town or county has its own building standards, that local code governs instead. Ask the local building department whether it issues permits and enforces a code; if it does not, the state's code applies and the Division of Housing is the office to call. Colorado tightened the model text rather than loosening it, replacing "immediate vicinity" in Section 915.2.1 with "within 15 feet".

What it turns on for a short-term rental:Coverage turns on a change of guests, and it does not wait on any building code. A whole-house short-term rental is answered by statute rather than by the code pathway that answers a hotel, and the statute is the stricter of the two. CRS 38-45-104(2) provides that each existing single-family dwelling, or dwelling unit in a multi-family dwelling, used for rental purposes that has a change in tenant occupancy on or after 1 July 2009 becomes subject to CRS 38-45-102 and 38-45-103. A booking is a change in occupancy, so the trigger fires at every turnover rather than once at sale. Subsection (1) adds the other route: permit-required interior alterations, repairs, fuel-fired appliance replacements or additions, or a new room lawfully used for sleeping. What the property then owes comes from 38-45-102 for a house and 38-45-103 for a unit. Where it has a fuel-fired heater or appliance, a fireplace, or an attached garage, an operational alarm goes within fifteen feet of the entrance to each room lawfully used for sleeping purposes, or where a state or local building code puts it. Nothing in Article 45 carves out transient letting, and subsection (5) is not an exemption but an alternative for a multi-family building with a centralised alarm system. Two consequences belong to letting by the night. Under 38-45-104(3)(a)(I) the owner must, before the commencement of each new occupancy, replace any alarm stolen, removed, found missing or found not operational after the previous one, which on a nightly cadence is a check between guests rather than a task for the start of a lease. And although 38-45-104(3)(b) says the owner is otherwise not responsible for maintenance or batteries, the duties it shifts to the occupant at subsection (4) are written-notice duties built for a tenancy, so across a two-night stay nobody but the host will perform them. Article 45 defines neither "rental purposes" nor "tenant", so a host in a jurisdiction that separates short-term letting from residential tenancy should ask the local authority how it reads those words.

Hotels already standing: not covered. Colorado imposes this on what gets built and nothing on a hotel that was standing when the rule took effect, so an operator of an older property carries no retrofit duty from it.

Operator duty: Two instruments reach a Colorado hotel and neither leaves a continuing duty on the operator. The one that reaches the building is the State Housing Board's, 8 CCR 1302-14, which adopts the 2021 International Building Code for site-built hotels, motels and multi-family structures in those areas of the state where no standards exist, and the Division of Housing issues the certificate of occupancy. That is a construction instrument: the duty attaches to design, construction and permitted work, and it is discharged at the certificate rather than carried forward by whoever runs the property afterwards. Colorado tightened the model text where it applies, replacing "immediate vicinity" in Section 915.2.1 with "within 15 feet". The fire code, which is where a continuing duty would ordinarily sit, does not reach lodging at all. 8 CCR 1507-101 adopts the 2021 International Fire Code only for property under the oversight of the Division of Fire Prevention and Control, and CRS 24-33.5-1203(1)(p) and (p.5) confine that oversight to public school and local district college buildings and to health facilities, and confine it there to construction plan reviews and inspections. The same confinement is why nothing reaches a building already standing. The retrofit chapter of the International Fire Code is the route that would carry a carbon monoxide requirement to an existing hotel, and in Colorado that chapter is never in force over one. Where a town or county has its own building standards, the local code governs and may say otherwise.

Penalties for Non-Compliance

Article 45 contains no specific penalty provisions, no fines, no criminal penalties. §38-45-106 provides a limitation of liability for compliant owners/installers. Local governments may impose penalties under their own ordinances per §38-45-105.

C.R.S. §38-45-101 through §38-45-106 (no penalty section exists)

Additional Notes

CRS Article 45 (§38-45-101 through §38-45-106) verified as comprehensive standalone CO alarm statute.
Article 45 never uses the words hotel or short-term rental, and the two halves of that silence are not the same. A hotel is genuinely outside it, which is why the lodging answer runs through the State Housing Board code at 8 CCR 1302-14. A whole-house short-term rental is not outside it at all: the statute reaches single-family dwellings, multi-family dwelling units and dwellings used for rental purposes, and that is what such a property is. CRS 38-45-104(2) picks it up on a change in tenant occupancy, so naming the building type rather than the letting arrangement is what puts the host inside the statute.

Local Rules That Differ From State Law

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

Aspen

Aspen threw out the state code section and wrote its own chapter, and one line of it puts the alarm somewhere Colorado law never does. Section 8.50.020 deletes Section 915 of the adopted fire code in its entirety and replaces it with Chapter 8.15 of the city code, which runs to purpose, definitions, responsibilities, installation and approval. Section 8.15.030 reaches every existing residential occupancy in the city, without waiting for a sale, a permit or a change of tenant, and puts installation and maintenance on the owner along with an immediate duty to repair or replace a defective detector once a tenant reports it, new batteries at the start of every tenancy, and written notice to the tenant of who is responsible for what. Section 8.15.040(b) is the sharp one: a detector goes inside each sleeping area that contains a fuel-burning appliance, naming gas logs, decorative gas fireplace appliances and wood-burning appliances. The state rule measures fifteen feet from the entrance to a sleeping room, which is a rule about the corridor; Aspen puts the device in the bedroom when the bedroom is the thing burning fuel, which in a town of gas-log fireplaces is not a small difference. Subsection (a) then offers an unusual escape from exact placement: a dwelling complies if the alarm is sited so that an audible signal of at least seventy decibels reaches each sleeping area. Hard wiring is required in new construction and in alterations that expose wall or ceiling finishes, unless an attic, crawlspace or basement offers a route.

Crested Butte

Crested Butte runs one of only two standalone municipal carbon monoxide articles in this survey, the other being Ocean City, Maryland's. Article 14 of Chapter 18 covers installation, testing, inspection, maintenance and liability. Section 18-14-30 requires every multiple-station detector installed under the article to be interconnected, and requires existing dwelling units to meet NFPA 720 or, failing that, to use a plug-in unit without a switch and with battery backup. Section 18-14-50 hands the owner a running duty rather than a one-off installation: batteries operable and supplied to the tenant when the tenant takes possession, replacement of any detector the tenant reports stolen, removed, missing or dead, and correction of any deficiency the tenant reports during occupancy. The article closes with Section 18-14-60, which shields an owner or installer from damages arising from a detector that fails, provided they installed, operated, maintained and tested it to the manufacturer's instructions and to the article. That is a bargain the state statute does not offer either side.

Crested Butte Town Code Chapter 18 Article 14, Carbon Monoxide Detector and Alarm Regulations, Sections 18-14-30, 18-14-50 and 18-14-60 Checked 2026-08-10.

Denver

Denver ties the alarm to two licences and makes its absence an offence in itself. Section 27-195(c) requires the holder of a residential rental property licence to keep a working smoke detector, carbon monoxide detector and fire extinguisher in every dwelling unit on the property, which covers long-term rentals across the city regardless of what is burning inside them. Section 33-49(a) does the same job for short lets from the other direction: it is unlawful to operate a short-term rental without a functioning carbon monoxide detector on the licensed premises. Neither provision waits for a fuel-fired appliance, a fireplace or an attached garage, and neither waits for a sale or a permit, so a Denver rental with an all-electric kitchen and no garage still owes a detector where the statute would not ask for one.

Boulder

Boulder is the city that sends an inspector to look. Its rental licensing sections, 10-3-6 for a building converted to rental property and 10-3-7 for renewal, both require the rental housing inspector to certify the condition and location of every smoke and carbon monoxide alarm in the rental inspection report. The duty being certified comes from Boulder's own property maintenance code, which Section 10-2-2 adopts with modifications, rewriting Section 705 so that alarms are required in existing residential structures under Title 38 Article 45 and in existing and rented single-family and multi-family dwellings with fuel-fired heaters, appliances or fireplaces. Section 10-3-19 adds a certification of operational smoke and carbon monoxide detectors to the short-term rental licence application. The state statute creates the duty and leaves proof of it to a dispute after the fact; Boulder checks at the licence and again at every renewal.

Boulder Revised Code Sections 10-3-6, 10-3-7 and 10-3-19, with the property maintenance code adopted and modified at Section 10-2-2 including Section 705 Checked 2026-08-10.

Steamboat Springs

Steamboat Springs makes the operator inspect and then makes the checklist enforceable. Section 12-543(a) makes it unlawful to run a short-term rental, a hosted short-term rental or a temporary short-term rental without working smoke detectors, carbon monoxide detectors and fire extinguishers on the licensed premises as identified on the short-term rental self-inspection checklist. Two things follow. The alarm is a condition of the licence rather than a consequence of what the building contains, so the fuel-fired trigger in the state statute drops out. And the checklist is incorporated into the offence, which means the document the operator fills in becomes the standard the town enforces against them.

Steamboat Springs Municipal Code Section 12-543(a), Chapter 12 Article IX Short-Term Rental Licensing Checked 2026-08-10.

What was checked:Colorado carries five municipal divergences, more than any other state in the fifty-one; California and South Dakota are next with four each. Seven municipalities were read on 2026-08-10, chosen to pair the Front Range with the mountain resort towns: Denver, Boulder, Fort Collins, Aspen, Steamboat Springs, Crested Butte and Estes Park. Five of the seven write something of their own and all five are below, a proportion only Maryland matches at three of four, and far above the one-city-in-nine that is usual elsewhere. Fort Collins is the one case left out on purpose. Its building chapter amends the 2024 International Residential Code to require carbon monoxide alarms placed as for new dwellings wherever permitted alterations, repairs or additions occur or a sleeping room is created, and it puts a combustion-air warning label into the fuel gas code. Both are close to what the model codes and C.R.S. 38-45-104(1) already say, so the city is enforcing the state answer rather than going past it, and a table entry would overstate it. Its third hit is a definition of volatile organic compounds. Estes Park carries nothing on carbon monoxide at all. Colorado's statute is what makes the local layer worth reading rather than skipping. C.R.S. 38-45-102 and 38-45-103 attach only where the dwelling has a fuel-fired heater or appliance, a fireplace or an attached garage, and they fire on sale, on permitted work or on a change of tenant occupancy. Four of the five entries below drop one or more of those conditions. The counties, the smaller resort towns and the unincorporated ski areas were not searched.

Frequently Asked Questions

What statewide statute anchors Colorado CO alarm duties?

Colorado statewide legal baseline is Article 45 of Title 38, especially C.R.S. 38-45-102 through 38-45-106. Those sections establish when carbon monoxide alarms are required in covered single-family and rental contexts and how compliance interacts with code pathways. Operators should read the statute together with applicable building-code provisions such as IRC R315 placement references. This combined reading is important because obligations can depend on trigger events, occupancy, and local enforcement workflow. Using only one source often misses practical compliance details in Colorado projects.

When do sale or permit events trigger obligations in Colorado?

Colorado rules can trigger alarm obligations during property transfer, permit-based renovation, and other statutory events identified in C.R.S. 38-45 pathways. In addition, source conditions such as fuel-burning appliances or attached garages influence when placement is required. For owners, this means transaction teams and construction teams should coordinate early instead of treating CO alarms as a final checklist item. Documenting trigger date, inspection status, and corrective action is a practical control that reduces disputes and helps show compliance during underwriting and closing.

How are rental responsibilities split in Colorado?

Colorado statute language in C.R.S. 38-45-104 separates owner and tenant duties. Owners generally handle installation, replacement between tenancies, and correction after written notice, while tenants are expected to maintain operability and report deficiencies they cannot resolve. This allocation should be mirrored in lease documents and move-in packets so expectations are enforceable and clear. Property managers should keep notice logs and repair timelines because post-incident disputes often depend on documentation quality more than verbal policy statements.

For Colorado all-electric homes, what conditions prevent automatic exemption?

All-electric homes may fall outside some source-based triggers, but Colorado owners should verify the full statutory and code context before concluding a unit is exempt. Attached garages, shared building systems, or neighboring combustion equipment can still affect risk profile in multifamily settings. Local code officials evaluate actual conditions, not only appliance labels. Many operators install alarms in borderline cases as a defensive safety measure and keep written rationale in the compliance file. That practice can reduce conflict during inspections and property transfer diligence.

Where should alarms be placed under Colorado code language?

Colorado placement references generally align with IRC R315 logic, including detector location outside sleeping areas and proximity considerations for covered dwellings. When fuel-burning equipment is near sleeping rooms, additional placement may be required by adopted code text. Builders should verify exact local amendments and inspection expectations before installation because municipal code editions can differ. Keeping approved placement plans, listing documentation, and as-built photos helps project teams close permits efficiently and defend compliance decisions after occupancy.

In Colorado portfolios, which procedure differs most from Utah alarm workflows?

Colorado combines a dedicated statewide statute in C.R.S. 38-45 with code-based placement pathways, while Utah frameworks rely on a different blend of statute and code triggers. Regional operators should avoid one shared template and instead map each state requirements by trigger event, occupancy, and inspection process. Colorado files should emphasize Article 45 responsibilities and local code implementation records. For a nearby-state comparison before finalizing western-region procedures, review Utah CO detector laws.
