Carlsbad FAQ
Do I need hard-wired smoke alarms in my Carlsbad home?
Existing homes can keep battery-only alarms, but any addition, alteration, or repair exceeding $1,000 triggers California Building Code Section R314 requirements for hard-wired, interconnected alarms with battery backup.
Can I get free smoke alarms in Carlsbad?
Yes. The Carlsbad Fire Department partners with the American Red Cross to install free 10-year smoke alarms, and with the Burn Institute for free CO alarms for residents aged 62 or older. Call 442-339-2665 to schedule.
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.
