New Mexico Carbon Monoxide Detector Law
What homeowners and renters in New Mexico need to know about CO detector requirements.
The Law in Plain English
No statewide mandate. Albuquerque and Santa Fe have local requirements.
What This Means for Homeowners & Renters
New Mexico does not have a comprehensive statewide carbon monoxide detector mandate, but some municipalities — notably larger cities — have enacted local ordinances requiring CO detectors. Homeowners and renters should contact their local fire marshal or building department to determine whether a requirement applies to their specific address. Regardless of local law, voluntary CO detector installation is strongly recommended in any home with gas appliances, oil furnaces, or an attached garage.
Landlord Requirements in New Mexico
Landlord requirements vary — check your local municipality or lease agreement.
Check your lease agreement and contact your local housing authority or fire marshal's office to determine whether a CO detector requirement applies to your rental unit. Requirements often differ between cities, counties, and building types (single-family vs. multifamily).
Recommended CO Detector Placement
Regardless of what New Mexico law requires, safety experts recommend placing CO detectors on every level of your home, within 10 feet of each sleeping area, and near any fuel-burning appliance (furnace, water heater, gas stove, fireplace). Replace your CO detector every 5–7 years — electrochemical sensors degrade over time regardless of whether the device appears functional.
