Summary
California Health & Safety Code 13113.7 requires State Fire Marshal-approved smoke alarms in every dwelling intended for human occupancy. In unincorporated San Diego County this state law is enforced by County building officials, with alarms in each bedroom, outside sleeping areas, and on every level.
Except as otherwise provided in this section, smoke alarms, approved and listed by the State Fire Marshal pursuant to Section 13114 at the time of installation, shall be installed, in accordance with the manufacturer's instructions in each dwelling intended for human occupancy.
Full Breakdown
Under HSC 13113.7, smoke alarms approved and listed by the State Fire Marshal must be installed per the manufacturer's instructions in each dwelling intended for human occupancy. Placement requires one alarm in each sleeping room, one in the hallway outside the sleeping rooms, and at least one per floor. At the sale of a single-family home, an operable approved alarm must be installed and the seller must give the buyer a written statement of compliance. San Diego County adopts the California Residential and Fire Codes, which for new construction also require interconnected, hardwired alarms with battery backup.
Violations & Fines
Noncompliance can block a certificate of occupancy or sale; HSC 13113.7 allows civil penalties up to $200 per offense, and County building/fire inspectors can order correction.
