Summary
California Health and Safety Code §13113.7 requires working smoke alarms in every dwelling unit, with hardwired interconnected alarms in new construction and battery alarms acceptable in older homes. Corona enforces this at sale of property, on remodel permits, and through fire and code enforcement inspections.
(a) (1) 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.
(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.
(b) "Dwelling units intended for human occupancy," as used in this section, includes a one- or two-unit dwelling, lodging house, apartment complex, hotel, motel, condominium, stock cooperative, time-share project, or dwelling unit of a multiple-unit dwelling complex, or factory-built housing as defined in Section 19971.
(e) A violation of this section is an infraction punishable by a maximum fine of two hundred dollars ($200) for each offense.
Full Breakdown
7 establishes the statewide smoke alarm requirement that Corona enforces locally. Every single-family home, multi-family unit, and lodging unit must have working smoke alarms in each sleeping room, in the hallway outside sleeping rooms, and on every level including basements. Alarms in residences sold or substantially remodeled after January 1, 2014 must be 10-year sealed lithium battery models or hardwired with battery backup, and California State Fire Marshal listed. New construction and additions valued over $1,000 must install hardwired interconnected smoke and carbon monoxide alarms throughout per current California Building Code requirements (CRC R314 and R315).
At point of sale, the seller must certify smoke and CO alarm compliance on the Real Estate Transfer Disclosure Statement. Riverside County Fire Department, providing fire services to Corona under contract, conducts inspections at multi-family complexes and short-term rental permit issuance/renewal verifying alarm presence and function. Battery alarms older than 10 years must be replaced regardless of operational status. Corona also enforces carbon monoxide alarm requirements in any home with a fuel-burning appliance, attached garage, or fireplace under H&S §13260.
