Summary

California State Fire Marshal regulations require working smoke alarms in every bedroom, outside each sleeping area, and on every floor of all dwellings. Alarms installed after 2015 must be 10-year sealed-battery models. Oakley enforces installation at point of sale and during permitted remodels. Carbon monoxide alarms are required in any home with fuel-burning appliances or attached garages under Health & Safety Code Section 13261.

13113.7.

(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.

(4) Unless prohibited by local rules, regulations, or ordinances, a battery-operated smoke alarm, which otherwise met the standards adopted pursuant to Section 13114 for smoke alarms at the time of installation, satisfies the requirements of this section.

(d) (2) The owner of a hotel, motel, lodging house, apartment complex, or other multiple-dwelling complex in which units are rented or leased, and commencing January 1, 2014, the owner of a single-family dwelling that is rented or leased, shall be responsible for testing and maintaining alarms required by this section.

(B) At the time that a new tenancy is created, the owner shall ensure that smoke alarms are operable. The tenant shall be responsible for notifying the manager or owner if the tenant becomes aware of an inoperable smoke alarm within his or her unit.

Full Breakdown

8 and State Fire Marshal regulations (Title 24 and Title 19) require smoke alarms in every dwelling unit. Required locations are inside every bedroom, outside each sleeping area (hallway within 21 feet of a bedroom door), and on each additional story of the dwelling including basements. New construction and major remodels (permitted work exceeding $1,000) must install hardwired, interconnected smoke alarms with battery backup. For existing homes, battery-only units installed or replaced after July 1, 2015 must be 10-year sealed-battery models bearing the California State Fire Marshal approval.

Carbon monoxide alarms are required under Health & Safety Code Section 13261 in any dwelling with a fuel-burning appliance (gas furnace, water heater, stove, fireplace), an attached garage, or a fireplace. CO alarm placement mirrors smoke alarms: outside each sleeping area and on every level. Combination smoke/CO alarms meeting UL 217 and UL 2034 satisfy both requirements. At the time of sale, sellers must certify compliance via the Real Estate Transfer Disclosure Statement, and escrow typically requires a smoke/CO alarm compliance inspection. Rental properties must have functional alarms at the start of each tenancy, with landlords responsible for initial installation and tenants responsible for replacing batteries and notifying landlords of defects.

Tampering with or disabling alarms is prohibited. The East Contra Costa Fire Protection District offers free smoke alarm installation for qualifying seniors and low-income households through community risk-reduction programs. Alarms should be tested monthly and replaced every 10 years regardless of battery life.

Frequently Asked Questions

Do I need to upgrade my older smoke alarms?
If your alarms were installed before 2015 and use replaceable batteries, they still must be functional but may be replaced with 10-year sealed-battery models at next replacement. All alarms should be replaced every 10 years regardless.
Are carbon monoxide alarms really required in all homes?
Yes, if your home has any fuel-burning appliance (gas furnace, water heater, stove, fireplace) or an attached garage. Only all-electric homes without attached garages are exempt.
