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

Yuba County has adopted the uniform building and fire codes required by the California Building Standards Commission, so smoke and carbon monoxide alarm requirements in the unincorporated county track California state law rather than a unique county ordinance. California Health & Safety Code section 13113.8 requires that every single-family dwelling that is sold have an operable smoke alarm approved and listed by the State Fire Marshal, installed in accordance with the State Fire Marshal's regulations. Under the California Building Code and Fire Code, smoke alarms must be installed in each sleeping room, in the hallway or area immediately outside each sleeping area, and on every story of the dwelling including basements. Carbon monoxide alarms are required by the Carbon Monoxide Poisoning Prevention Act (Health & Safety Code section 13260 et seq.); a carbon monoxide alarm must be installed in any dwelling unit that has a fuel-burning appliance or fireplace, or an attached garage. At least one State Fire Marshal-approved carbon monoxide device must be installed at the point of sale of residential property. These device requirements are especially important in foothill homes that rely on propane heaters, wood stoves, and generators. New construction and major remodels in the unincorporated county must meet the current California Codes (the county notes plans submitted on or after January 1, 2020 must comply with the then-current California Codes).
