Most Homeowners Will Need to Install Carbon Monoxide Detectors by July 1st 

The City of Escondido has launched a community outreach effort to inform community residents that on July 1, 2011 many homes will be required to install carbon monoxide detectors.

The Federal Centers for Disease Control and Prevention estimate that carbon monoxide kills approximately 500 people each year and injures another 20,000 people nationwide. In an effort to prevent these accidental deaths and injuries, the California legislature enacted SB 183 (Lowenthal) which mandates owners of dwellings intended for human occupancy to install carbon monoxide devices in existing dwelling units having a fossil fuel, (natural gas or propane) fuel-burning heater or appliance, fireplace, or attached garage. ("Fossil fuel" means coal, kerosene, oil, wood, fuel gases, and other petroleum or hydrocarbon products, which emit carbon monoxide as a byproduct of combustion).

CO devices must be installed in all single-family dwellings, including factory-built, by July 1, 2011 as specified above (having fossil-fuel, fireplace, attached garage). All other specified dwelling units, (duplex, lodging house, dormitory, hotel, motel, condominium, stock cooperative, time-share project, or dwelling unit in a multiple-unit dwelling unit building or buildings), must have CO devices installed by January 1, 2013. The Office of the State Fire Marshal (SFM) has developed a list of certified CO devices that meet the requirement specified within the Carbon Monoxide Poisoning Prevention Act of 2010. For a complete list of currently approved devices please visit the SFM’s website at Under the search categories provided select Carbon Monoxide Alarms and Carbon Monoxide Detectors for a complete list of devices.

Further details contained within the Carbon Monoxide Poisoning Prevention Act of 2010:

Owners shall install CO devices in a manner consistent with building standards applicable to new construction for the relevant type of occupancy if it is technically feasible. See the 2010 California Building Code, Section 420.4, and the 2010 California Residential Code, Section R315.

  • CO devices shall produce a distinct audible alarm.
  • CO devices may be combined with a smoke detector, if the combination device meets all specified SFM listing and approval requirements.
  • Violation of Health & Safety Code Section 17926 is an infraction punishable by a maximum fine of two-hundred dollars for each offense.
  • A local enforcement agency shall provide the property owner a 30-day notice to correct.
  • Local jurisdictions are authorized to adopt ordinances requiring CO devices if the ordinance is consistent with the requirement of this bill.

For a full list of this legislation’s stipulations please review the Department of Housing and Community Development’s Information Bulletin 2011-01 at
