Des Plaines enforces the Illinois Smoke Detector Act (425 ILCS 60/), as amended in 2023, which requires 10-year sealed-battery smoke alarms in all single-family and multi-family dwellings. Alarms must be installed inside each sleeping area, outside each sleeping area, and on every floor including the basement.
Under the Illinois Smoke Detector Act (425 ILCS 60/) as amended effective January 1, 2023, every dwelling unit in Des Plaines must have working smoke alarms. New installations and replacements in homes lacking hardwired alarms must use 10-year sealed-battery alarms β replaceable-battery models are no longer compliant for new installs. Required locations include inside each sleeping room, outside each separate sleeping area within 15 feet of the bedroom door, and on every level of the home including basements. Hardwired alarms with battery backup installed before 2023 may remain in service. CO detectors are separately required under the Carbon Monoxide Alarm Detector Act (430 ILCS 135/) within 15 feet of every sleeping area in any home with a fuel-fired appliance or attached garage. The Des Plaines Fire Department conducts free in-home alarm checks; call (847) 391-5333.
Lack of required smoke alarms is a code violation with fines of $100 to $500 per occurrence. Landlords face additional penalties for non-compliant rental units, and rental inspections will fail if alarms are missing or non-compliant.
