Joliet, IL Public Conduct: Public Alcohol Use (2026)

Section 4-40(a) prohibits possessing alcoholic liquor on a public way except in an unbroken original package, unless the area has been designated licensed premises by the liquor commissioner under Section 4-15. Section 4-40(b) extends the same unbroken-package rule to public libraries and public mass transit facilities. 1(a) goes further for certain private and semi-public spaces, banning any open or unsealed alcoholic beverage, regardless of packaging, on a publicly accessible parking lot or garage, on the exterior of business property open to the public or used for anything other than a permitted residential use, or on a vacant lot accessible to the public whether or not the owner has consented.

1(b) exempts any location specifically licensed by the Joliet Liquor Control Commissioner to permit sale or consumption. ' Together the two sections create two different standards depending on location: an unbroken original package is enough on a public way, library, or transit facility, but on parking lots, business exteriors, and accessible vacant lots even a sealed but opened container is unlawful. Neither section carries a dedicated entry in the Chapter 1 fine schedule, so the Code's general penalty applies.
