El Cajon FAQ
Does San Diego County have its own smoke detector law for homes?
No. Residential smoke alarm requirements come from California state law (Health & Safety Code 13113.7 and 13113.8) and the California Building/Residential Codes that the County adopts, not a separate county ordinance. Alarms must be State Fire Marshal-listed and in every bedroom.
Do I need smoke alarms to sell my home?
Yes. Under Health & Safety Code section 13113.8, every single-family dwelling sold must have an operable, properly located smoke alarm at the date of title transfer, and the seller must give the buyer a written statement of compliance.
Vista FAQ
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.
