Carbon Monoxide Detector Requirements

Timeline - Although the bill was signed into law in 2010, California residents must have carbon monoxide detectors in their homes as of July 1, 2011. This timeline applies only to single-family homes that have appliances that burn fossil fuels or homes that have attached garages or fireplaces. For all other types of housing, such as apartments and hotels, detectors should be in place as of January 1, 2013. Types of fossil fuels include wood, gas and oil.

Detector - According to California Senate Bill 183, the detector must sound an audible warning once carbon monoxide is detected. It also must be powered by a battery, or if it is plugged in, have a battery for a backup. The detector also must be certified by national testing labs, such as the Underwriters Laboratories and be approved by the California State Fire Marshall. The packaging on the carbon monoxide detector will state this. If the CO detector is also a smoke detector, it must still meet the above standards and must sound an alarm that is different than the smoke alarm.

Location - The CO detectors should be located at each level of the structure and at common areas serving the bedrooms and or sleeping areas. Carbon monoxide detectors should be placed at least 15 feet away from heating and cooking appliances. Do not install detectors in humid areas, such as bathrooms.
