Glenn County, CA Fire Regulations: Smoke Detectors (2026)

We found no Glenn County-specific smoke-detector ordinance distinct from state law; the controlling rules are statewide and enforced by the standards Glenn County adopts. California Health & Safety Code section 13113.7 requires smoke alarms in every dwelling unit intended for human occupancy — including single-family homes, duplexes, apartments, condominiums, hotels, and motels. Alarms must be installed in each bedroom, outside each sleeping area (in the hallway serving the bedrooms), and on every level of the home, including basements. Since July 1, 2014, the State Fire Marshal has required battery-operated smoke alarms sold in California to contain a non-replaceable, non-removable battery capable of powering the alarm for at least 10 years, and alarms must be replaced 10 years from their manufacture date. The California Residential Code (Title 24) carries parallel placement requirements for new construction and additions, and Glenn County's building program applies the adopted California Building Standards Code to unincorporated construction. For rental property, landlords are responsible for testing and maintaining smoke alarms, and since January 1, 2014 owners of rented single-family homes carry the same obligation. Many jurisdictions also recommend or require carbon monoxide alarms in homes with attached garages or fuel-burning appliances under related state law. These requirements apply countywide regardless of incorporated/unincorporated status.
