Martinez, CA Fire Regulations: Smoke Detectors (2026)

California Health & Safety Code §13113.7 and the California Residential Code (CRC R314) require smoke alarms in every residential unit. In Martinez, enforcement is handled through Contra Costa County Fire Protection District (ConFire / CCCFPD) and the Martinez Building Division. Alarms must be installed: inside each sleeping room, outside each separate sleeping area (hallways serving bedrooms), and on every story of the dwelling including basements. Since July 1, 2014, all newly installed battery-only smoke alarms sold in California must have a non-removable 10-year sealed battery and a hush feature per SB 745. Hardwired alarms with battery backup are required for new construction and major remodels. Carbon monoxide alarms are also required in any dwelling with a fossil-fuel appliance or attached garage under HSC §17926 (Carbon Monoxide Poisoning Prevention Act). At property sale or transfer, sellers must certify smoke and CO alarm compliance — this is typically handled via the Real Estate Transfer Disclosure Statement. Landlords must provide working alarms at tenant move-in; tenants are responsible for battery replacement during tenancy unless otherwise agreed. Missing or non-functional alarms can trigger code enforcement action, and in rental properties, habitability complaints. ConFire offers free smoke alarms to qualifying low-income households through its community risk reduction program.
