California Health & Safety Code Section 13113.7 and Title 24 require working smoke alarms in every bedroom, outside sleeping areas, and on each floor of all Brentwood dwellings. Units built or substantially remodeled since 2015 must have 10-year sealed lithium battery or hardwired interconnected alarms. Carbon monoxide alarms are also mandatory under SB 183.
All residential dwellings in Brentwood must comply with California smoke alarm requirements codified in Health and Safety Code Section 13113.7 and California Building Code Chapter 9. A working smoke alarm is required inside each sleeping room, in hallways immediately outside sleeping rooms, and on every level of the home including basements. Alarms installed since July 2015 must be either hardwired with battery backup or contain a non-removable 10-year sealed lithium battery, and new construction requires interconnected units that all sound together when one activates. Landlords are responsible for installation and initial testing before occupancy; tenants are responsible for notifying the owner of malfunctions. Carbon monoxide alarms are required in all dwellings with fuel-burning appliances, fireplaces, or attached garages under Senate Bill 183 and must be installed outside each sleeping area. Real estate sellers must disclose and certify compliance at close of escrow. ECCFPD inspects alarms during any fire response and issues correction notices for missing or disabled units. Sale of ionization-only alarms without hush features is prohibited.
