Carbon monoxide detectors are not required in Texas homes under any statewide law. The Texas Property Code requires landlords to install smoke alarms in rental units but says nothing about CO alarms, and the state leaves residential building codes to local governments. The one clear statewide mandate applies to licensed child-care operations. Whether a CO detector is required at your address usually comes down to your city or county’s building code and the type of building you’re in.
No Statewide Rule for Homes
Texas Health and Safety Code Chapter 766 defines a carbon monoxide alarm as a device that detects harmful levels of CO gas and sounds an alarm, but the chapter does not require homeowners across the state to install one. The Texas Department of Insurance and the State Fire Marshal’s Office treat CO safety as a public education issue, recommending alarms on every floor and outside every sleeping area rather than mandating them.1Texas Department of Insurance. How to Avoid Carbon Monoxide Poisoning at Home
Practically, that means a Texas homeowner faces no state penalty for not having a CO detector. The gap is worth taking seriously anyway. The CDC reports more than 100,000 emergency room visits for accidental CO poisoning each year nationwide, and over 600 of those cases are fatal.2USAFacts.

What Landlords Must and Must Not Do
Texas Property Code Chapter 92, Subchapter F sets detailed rules for smoke alarms in rentals. A landlord must install at least one smoke detector in each sleeping room, make sure it works when a tenant moves in, and repair it within a reasonable time after a tenant reports a problem.3State of Texas. Texas Property Code 92-251 – Definitions The statute defines “smoke alarm” as a device that detects visible and invisible products of combustion. It does not mention carbon monoxide detectors.
The tenant enforcement tools in Subchapter F, including remedies for a landlord’s failure to install or repair, apply only to smoke alarms. A tenant cannot use those provisions to demand a CO detector from a landlord.4State of Texas. Texas Property Code 92-258 – Inspection and Repair
That is not the end of a landlord’s exposure, though. General negligence principles still apply to the condition of the property. A malfunctioning furnace, water heater, or other fuel-burning appliance that leaks CO into a living space can support liability if the landlord knew or should have known about the problem and failed to fix it. The claim would be framed as a failure to maintain the property in a safe condition, not a failure to install a detector. If your rental has gas appliances or an attached garage, asking the landlord to install a CO alarm is reasonable, and buying a plug-in or battery unit yourself is inexpensive.
New Construction and Local Building Codes
Texas does not impose a single statewide residential building code. Cities and counties choose which edition of the International Residential Code to adopt and enforce, so the answer to “is a CO alarm required in this new house?” depends on the jurisdiction. The exception is industrialized (factory-built) housing, which must comply with the 2021 edition of the IRC under rules administered by the Texas Department of Licensing and Regulation.5Texas Department of Licensing and Regulation. Industrialized Housing and Buildings Mandatory Building Codes
Section R315 of the IRC is the provision that drives most CO alarm rules in new Texas homes. It requires CO alarms in any dwelling unit that has a fuel-burning heater or appliance, a fireplace, or an attached garage. The alarms must be placed outside each sleeping area and on every occupiable level, including basements. In new construction, they must be hardwired with battery backup, and when more than one alarm is required, all of them must be interconnected so that triggering one sets off every alarm in the unit.
Whether R315 applies to a specific home depends on which IRC edition your city or county has adopted. The City of Abilene, for example, requires CO alarms in both new and existing dwellings with attached garages or fuel-burning appliances, following the IRC’s placement and interconnection standards.6City of Abilene. Owner/Contractor Certification of Smoke/Carbon Monoxide Detector and Vent Compliance Most Texas cities on a recent edition of the IRC will have similar rules. If you’re building or doing a major renovation, confirm the current requirements with your local building department.
Day-Care and Child-Care Facilities
Child care is the one setting where Texas law is explicit. Under Human Resources Code Section 42.060, every day-care center, group day-care home, and family home must have carbon monoxide detectors installed according to rules adopted by the Health and Human Services Commission. The executive commissioner sets the specifics for placement, number of detectors, and maintenance.7State of Texas. Texas Human Resources Code 42-060 – Carbon Monoxide Detectors
One narrow exception exists. A day-care center located in a school facility that already meets the standards adopted by the commissioner of education under Education Code Section 46.008, or similar standards adopted by a local school district board, is exempt.7State of Texas. Texas Human Resources Code 42-060 – Carbon Monoxide Detectors For every other licensed child-care operation, the requirement is mandatory and does not depend on whether the building has fuel-burning appliances.
How to Confirm What Applies Where You Live
Because CO detector rules in Texas come almost entirely from local adoption of the building code, your address determines your answer. Major Texas cities on recent IRC editions generally require alarms in homes with fuel-burning appliances or attached garages. Smaller jurisdictions may not have adopted any residential building code, leaving homeowners without any legal requirement.
Contact your local building or code enforcement department and ask two questions. First, which edition of the IRC, if any, does the jurisdiction enforce? Second, does any local ordinance separately require CO detectors in existing homes or rentals, such as at a change of occupancy or when a property is sold? Some Texas jurisdictions do go beyond the IRC and reach existing housing that way.
If You Install One Anyway
Most Texans installing CO alarms are doing so voluntarily, and a few habits keep the equipment useful. The TDI recommends placing an alarm outside every sleeping area and on every level of the home, and keeping furniture and curtains from blocking the units.1Texas Department of Insurance. How to Avoid Carbon Monoxide Poisoning at Home The EPA suggests mounting detectors on a wall about five feet above the floor or on the ceiling.8US Environmental Protection Agency (EPA). Where Should I Place a Carbon Monoxide Detector?
Sensors also wear out. The TDI advises replacing alarms every 10 years or when the end-of-life signal sounds, whichever comes first, and testing units monthly with the test button.1Texas Department of Insurance. How to Avoid Carbon Monoxide Poisoning at Home The end-of-life chirp is different from the low-battery warning; it means the sensor itself is no longer reliable, and the whole unit needs replacing. If your alarm ever sounds, get everyone out and call 911 from outside rather than reentering to open windows or hunt for the source.
