Corona, CA Fire Regulations: Smoke Detectors (2026)

California Health and Safety Code §13113.7 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.
