Full Breakdown

Berkeley Municipal Code Chapter 19.48 adopts the California Residential Code and State Health and Safety Code Section 13113.7, requiring hardwired interconnected smoke alarms with battery backup in every sleeping room, outside each sleeping area, and on every story of a dwelling. Existing homes may use 10-year sealed battery alarms when retrofit wiring is impractical. Carbon monoxide alarms (per SB 183) are required outside each sleeping area and on every level of homes with any fuel-burning appliance, fireplace, or attached garage. Rental units must have alarms tested and verified at each tenant turnover; landlords carry written responsibility. At the time of sale, the seller must certify functional alarms (California Civil Code 1102.155). Any building permit for a bedroom addition, kitchen remodel, or reroof triggers city-wide alarm upgrades to current code. Berkeley Fire offers free smoke alarms to qualifying seniors and low-income residents via the American Red Cross Home Fire Campaign. Contact BFD at (510) 981-2489.

Frequently Asked Questions

Are hardwired alarms mandatory in my older Berkeley home?
Hardwiring is required for new construction and remodels. Existing homes may use 10-year sealed lithium battery alarms if meeting UL 217 standards, but any permit work triggers upgrade requirements.
Do I need CO alarms if my home is all-electric?
Only if you have an attached garage. Fully electric homes with no attached garage and no fuel-burning fireplace are exempt under SB 183, though alarms are still recommended.
