Full Breakdown
Sacramento County does not have a unique residential smoke-alarm standard; the requirements come from statewide California law applied through the adopted building and fire codes. 7 requires that smoke alarms be installed in every dwelling intended for human occupancy, with alarms inside each bedroom, outside each separate sleeping area (such as a hallway), and on each level of the unit including basements. On and after January 1, 1986, every single-family dwelling and factory-built home that is sold must have an operable smoke alarm approved and listed by the State Fire Marshal and installed per the State Fire Marshal's regulations.
) in all dwelling units that have a fuel-burning appliance (gas furnace, water heater, stove), a fireplace, or an attached garage; CO alarms must be placed outside each sleeping area and on every level including basements. Combination smoke/CO alarms are allowed if listed by the State Fire Marshal. 1 also makes working smoke alarms part of habitability). New construction triggers additional placement and power-source requirements (hard-wired with battery backup, or 10-year sealed-battery devices) under the California Building/Residential Code.
Violations & Fines
Smoke-alarm non-compliance is enforced through code enforcement and habitability law; for rentals it can support a habitability claim under Civil Code Section 1941.1, and Health and Safety Code Section 13113 provides for penalties for violations of the smoke-alarm requirements. At point of sale, sellers of single-family homes must certify smoke-alarm compliance. Failure to maintain required CO alarms exposes owners to liability under the Carbon Monoxide Poisoning Prevention Act.
