Joliet, IL Fire Regulations: Smoke Detectors (2026)

Section 8-335 of the Joliet Code adopts the International Property Maintenance Code, 2015 Edition, and amends two of its sections. Amended § 704.2 requires single- and multiple-station smoke alarms in existing Group I-1 and R occupancies, tying the local mandate directly to the Illinois Smoke Detector Act (425 ILCS 60/3); if the state act and the city's rule conflict, whichever sets the stricter standard controls. Added § 704.5 requires carbon monoxide alarms throughout every dwelling under the state Carbon Monoxide Alarm Detector Act (430 ILCS 135/), placed within 15 feet of every room used for sleeping, with at least one alarm in that 15-foot zone in any structure holding more than one dwelling unit; the alarm may be battery powered, plug-in with battery backup, or hardwired with battery backup, and may be combined with a smoke detector if it clearly differentiates the two hazards.

Responsibility splits by building type. In non-R-2/R-3 buildings the owner installs and maintains all fire safety equipment. In R-2 and R-3 buildings the owner installs and maintains equipment in common areas and must give at least one tenant per unit written testing and maintenance instructions; the tenant maintains the equipment inside the unit, replaces batteries (except the owner must ensure batteries work at move-in), and must notify the owner in writing of any deficiency the tenant can't fix. No owner-occupant may occupy, and no owner may let another occupy, a unit that doesn't comply.

Enforcement sits with the Department of Community and Economic Development's Neighborhood Services Division (§ 103.1). Amended § 106.4 makes any IPMC violation a strict-liability offense punished as prescribed by law, with each day the violation continues after notice counted as a separate offense; unresolved cases go to civil abatement under § 106.3, and the city's costs become a lien on the property.
