Smoke detector rules, ‘Salt District’ proposal set for zoning approval as industrial crackdown ordinance remains in limbo 

Aldermen are scheduled on Tuesday to revive up a long-stalled ordinance (O2019-8529) that would require all Chicago homes to have modern smoke detectors installed within the next decade. 

Introduced in 2019 by Ald. Gilbert Villegas (36), the ordinance requires all residential property owners whose smoke detectors expire after 2022 to replace them with “a self-contained, non-removable, long term battery” alarm.
