New California Carbon Monoxide Laws
It’s the Law
Senate Bill 183 in California requires Carbon Monoxide Alarms for dwelling units intended for human occupancy with a fuel burning appliance, fireplace or attached garage.
Effective date of this law is January 1, 2011 for new construction, July 1, 2011 for existing single family dwellings and January 1, 2013 for all other.
“Dwelling unit intended for human occupancy” means a single-family dwelling, factory-built home as defined in Section 19971, duplex, lodging house, dormitory, hotel, motel, condominium, stock cooperative, time-share project, or dwelling unit in a multiple-unit dwelling building.
The code states “With respect to the number and placement of carbon monoxide devices, the devices shall be installed in a manner consistent with building standards applicable to new construction for the relevant type of occupancy.” It is expected one alarm is required outside each sleeping room, on each story and in the basement.
Alarms are required to be approved by an nationally recognized testing laboratory (NRTL) such as UL or ETL to the ANSI/UL 2034 standard and be approved and listed by the California State Fire Marshal (CSFM). Alarms may be hardwired with battery backup, plug-in with battery backup or battery operated. Combination smoke and carbon monoxide alarms are also acceptable as long as they meet ANSI/UL 2034 and 217 standards.
Exemptions are included for buildings containing neither attached garage nor fossil fuel burning appliances.
