Tinley Park, IL Public Conduct: Loitering Rules (2026)

25 lists acts declared to be disorderly conduct, and subsection (B) targets loitering: it is unlawful to knowingly "loiter in or about any public park, public building, public street, public sidewalk, or other public thoroughfare, or in or about any private property which is generally open and accessible to the public," when the loitering causes a clear and present danger of riot, will clearly cause an immediate, actual, physically violent reaction from another person, causes actual interference, disturbance or annoyance to someone lawfully using the public property, or obstructs or interferes with the free and normal passage of pedestrians or vehicles.

Subsection (C) backs this with a dispersal rule: failing to depart or disperse from the same public places, or accessible private property, on the order of a police officer or other conservator of the peace given to prevent or suppress the enumerated conduct is itself a separate violation. 26 lets a court, instead of the standard fine, impose a sentence of supervision of up to one year, with conditions that can include restitution, community service, education programs, medical or psychiatric treatment, or school and residency requirements for a minor. Illinois's own disorderly conduct statute, 720 ILCS 5/26-1, is cross-referenced as the statutory backdrop for this village-level offense.
