What changed

HB4328 adds new requirements to 425 ILCS 60, specifically Section 3.1 (new) and Section 4 (amended). The bill prohibits selling, offering for sale, or giving as a gift any smoke detector that is not designed to receive primary power from building wiring or does not meet specified battery requirements. The prohibition takes effect December 31, 2027. The bill explicitly carves out an exception: manufacturing within Illinois for distribution outside the state is not prohibited. Violators are guilty of a petty offense subject to a fine.

Manufacturers and retailers of smoke detectors in Illinois should monitor this bill's progress through the legislative process. If enacted, affected parties must ensure all smoke detector products sold, offered for sale, or given as gifts in Illinois meet hardwiring or specified battery requirements by December 31, 2027. Manufacturers may continue producing non-compliant units for out-of-state sales. Retailers should begin reviewing inventory and supplier arrangements to ensure compliance by the effective date.
