Smoke Detectors: Bonsall vs Vista

Where do I have to install smoke alarms in an unincorporated San Diego County home?

Under California Residential Code Section R314.3 (adopted into County Code Title 9), smoke alarms must be installed in each sleeping room, outside each separate sleeping area in the immediate vicinity of the bedrooms, and on each additional story of the dwelling, including basements and habitable attics. Crawl spaces and uninhabitable attics are excluded. Alarms must be listed to UL 217 and comply with NFPA 72.

Do I have to upgrade my old smoke alarms when I remodel?

Yes. CRC R314.2.2 requires existing dwellings to be brought up to current smoke-alarm standards when a building permit is issued for alterations, repairs, or additions valued over $1,000. Where no wall or ceiling finishes are removed, the retrofit alarms may be battery-operated; otherwise, hardwired interconnected alarms with battery backup are required. The County PDS Building Division verifies compliance at final inspection.

Do I need to do anything about smoke alarms when I sell my house?

Yes. California Health and Safety Code Section 13113.8 requires the seller of a one- or two-unit single-family dwelling to deliver a written statement to the buyer before transfer of title confirming that the dwelling is in compliance with the smoke-alarm requirements. The exclusive remedy for failure to deliver the statement is actual damages up to $100, but failure does not invalidate the sale.

Where do smoke alarms have to be installed in a Vista home?

California Residential Code Section R314, enforced by Vista's Building Division, requires smoke alarms in each sleeping room, outside each separate sleeping area in the immediate vicinity of the bedrooms, and on each additional story of the dwelling, including basements and habitable attics. Crawl spaces and uninhabitable attics are excluded. For new construction or permitted alterations, alarms must be hardwired with battery backup and interconnected.

Do I need a hardwired smoke alarm to sell my Vista house?

Not necessarily. CRC R314 allows existing dwellings to keep battery-only smoke alarms when no construction is taking place, provided retrofitted units have a 10-year non-replaceable sealed battery. However, California Health & Safety Code 13113.8 requires the seller to give the buyer a written statement that the property complies with state smoke-alarm law, and at least one carbon monoxide alarm must be installed at point of sale.
