(2) For all dwelling units intended for human occupancy for which a building permit is issued on or after January 1, 2014, for alterations, repairs, or additions exceeding one thousand dollars ($1,000), the permit issuer shall not sign off on the completion of work until the permittee demonstrates that all smoke alarms required for the dwelling unit are devices approved and listed by the State Fire Marshal pursuant to Section 13114.
(4) Unless prohibited by local rules, regulations, or ordinances, a battery-operated smoke alarm, which otherwise met the standards adopted pursuant to Section 13114 for smoke alarms at the time of installation, satisfies the requirements of this section.

Full Breakdown
7 mandates smoke alarms in all dwellings used for sleeping. As incorporated into the California Residential Code section R314 and further amended by SB 745 (2013) and SB 1291 and related legislation, the current rules require installation of smoke alarms (1) in every bedroom, (2) in the hallway outside each separate sleeping area, and (3) on each additional story of the dwelling including basements and habitable attics. Alarms powered solely by a replaceable 9-volt battery cannot be sold or installed in California; replacement alarms must contain a nonremovable 10-year lithium sealed battery or be hardwired with battery backup, and must be listed by the State Fire Marshal.
When alterations, repairs, or additions requiring a permit exceed $1,000 and require entry to the existing dwelling, or when a bedroom is added, the entire dwelling must be brought up to current smoke alarm code. Interconnection of alarms is required in new construction so that when one alarm activates, all alarms sound. Sellers of single-family residences must provide a smoke alarm disclosure at the transfer of title. The Pittsburg Building Division enforces these provisions on permitted work, and Contra Costa County Fire Protection District inspects multi-family buildings and responds to alarm-related incidents.
