Idaho Carbon Monoxide Detector Law
What homeowners and renters in Idaho need to know about CO detector requirements.
The Law in Plain English
No statewide requirement. Check local municipality.
What This Means for Homeowners & Renters
Idaho does not have a statewide carbon monoxide detector law. However, individual municipalities may have their own requirements — homeowners and renters should check with local building or fire officials. Even without a legal mandate, the CDC and NFPA strongly recommend that every home with fuel-burning appliances or an attached garage have at least one CO detector installed near sleeping areas. Voluntary installation is the single most effective step any resident can take to prevent CO poisoning.
Landlord Requirements in Idaho
Not applicable — no state mandate currently in effect.
Because Idaho has no statewide mandate, there is no automatic landlord requirement under state law. However, some municipalities may have enacted local ordinances. Renters should verify with local housing authorities and are strongly encouraged to install their own CO detector regardless of legal requirements.
Recommended CO Detector Placement
Regardless of what Idaho 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.
