Smoke Detectors

Updated Illinois Smoke Detector Law

Illinois has updated its smoke detector law effective January 1, 2023. Starting on that date, any new smoke detector installed within a single or multi-family home is required to be an alarm that features a 10-year sealed battery. Exceptions are homes built after 1988 that already have hardwired smoke detectors, and homes with wireless integrated detectors that use low-power radio frequency communications, Wi-Fi, or other Wireless Local Area Networking capability.

Smoke alarms in single or multi-family homes prior to January 1, 2023 may remain in place until they exceed 10 years from the date of their being manufactured or fails to respond to operability tests or otherwise malfunctions.

Smoke Detector Location In The Home

A closed door may slow the spread of smoke, heat and fire. Put smoke alarms inside and outside each bedroom and sleeping area. Put alarms on every level of the home. Smoke alarms should be interconnected. When one sounds, they all sound.

Place smoke alarms on the ceiling or high on the wall. Check the manufacturer's instructions for the best place for your alarm.

Only qualified electricians should install hardwired smoke alarms.
