Tinley Park, IL Public Conduct: Public Alcohol Use (2026)

45, titled Sales, Consumption on Government Property, sits in Chapter 112's general regulations for licensed alcohol sales. It forbids selling, consuming, or delivering alcoholic liquor on or to any building or property belonging to or controlled by the United States government, the State of Illinois, or any political subdivision of the state, a category the section expressly extends to buildings, lots or parcels of real estate, public streets, rights-of-way, and easements. Because Tinley Park sits partly in Cook County and partly in Will County, the rule reaches village-owned and county-owned rights-of-way running through both.

The only way around the ban is specific authorization: state law, federal law, the Tinley Park Code itself, or the village's own Local Liquor Control Commissioner. That last route matters for the village's Special Event permit chapter (Ch. 105) and for licensed beer gardens or festivals on public property, where the Commissioner's approval creates the exception the general ban otherwise closes off. Absent that sign-off, drinking on a Metra station platform, a village sidewalk, or a public parking lot violates the section regardless of the drinker's age or how the liquor was obtained.
