Hayward FAQ
Are battery-only alarms still legal?
Yes in existing homes, but replacements must be 10-year sealed lithium units. New construction requires hardwired interconnected alarms.
Who is responsible in a rental?
Landlords must install and test at turnover; tenants must notify the landlord of any failure.
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.
