California residents must have carbon monoxide detectors in their homes as of July 1, 2011.
Who is impacted? This timeline applies to single-family homes, inclucing individually-owned condominiums, (owner or tenant occupied) that have appliances that burn fossil fuels or homes that have attached garages or fireplaces. Types of fossil fuels include coal, kerosene, oil, wood, fuel gases, and other petroleum or hydrocarbon products, which emit carbon monoxide as a byproduct of combustion.
For all other types of housing, such as apartments and hotels, detectors should be in place as of January 1, 2013.
How much does a CO detector cost? Approximately $20 to $60. If you own rental property, this is a critical, low cost item your property must have.
