The Law and Carbon Monoxide 2/13/13


Contractors, Owner-Builders; Property Owners, and Tenants:  Please be aware that Senate Bill – SB 183 requires all single-family homes with an attached garage or a fossil fuel heat source (wood, coal, propane, oil, kerosene, etc.) to install carbon monoxide alarms within the home beginning July 1, 2011, and owners of multi-family leased or rented dwellings, such as an apartment building, are required to comply with the law by January 1, 2013. There are two types of Carbon Monoxide (CO) devices.  The most typical that is installed in a single family home is the carbon monoxide alarm which has its own built-in power supply and audible signal.  Most importantly, please be aware that the carbon monoxide device must be one that has been pre-approved by the State Fire Marshall (SFM).  SB-183 prohibits the marketing, distribution, or sale of devices that are not approved and listed by the State Fire Marshall.  You can find a list of State Fire Marshall approved devices at http://osfm/ or email ( or call the Sierra County Building Department at 530-289-3251 if you should need assistance.  Thank you.
