Effective January 1, 2023 any new smoke alarm being installed within a single or multi-family home must be a type with a long-term, ten year sealed battery. Smoke alarms in single or multi- family homes prior to January 1, 2023 may remain in place until they exceed ten years from their manufactured date, fails to respond to operability tests, or otherwise malfunctions.
Homes built after 1988 may already have hardwired smoke alarms and would be exempt from the new law. Homes with wireless integrated alarms that use low-power radio frequency communications, Wi-Fi, or other Wireless Local Area Networking capability are also exempt.
