Berkeley FAQ
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.
Oakland FAQ
Do I need hardwired smoke alarms in an older Oakland home?
Not unless you pull a permit for alterations/additions over $1,000 or add a bedroom. Otherwise 10-year sealed battery alarms meeting State Fire Marshal certification satisfy the law in existing homes.
Who replaces smoke alarms in a rental — landlord or tenant?
The landlord is responsible for installation and for replacement/repair once notified in writing by the tenant. The tenant is responsible for routine testing and replacing standard batteries in non-sealed units.
