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.
Sunol FAQ
Do I need to replace smoke alarms when selling my home?
Yes. State law requires compliance at point of sale, including current model alarms in all required locations certified by the seller.
Who is responsible for batteries in a rental?
Landlord tests and ensures operability at move-in. Tenants must maintain batteries and notify landlord of malfunctions in writing.
