Summary

Rock Island County makes it unlawful for anyone under 21 to purchase, accept delivery of, possess, or consume alcoholic liquor anywhere in the county. § 130.02 carves out only a religious-ceremony exception and parent-supervised drinking at home, and a first citation under the section costs $50, rising to at least $75 after that.

These county ordinances apply to unincorporated areas of Rock Island County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(A) Possession of alcoholic liquor by persons under 21. It shall be unlawful for any person under 21 years of age to purchase, accept delivery, or have possession of any alcoholic liquor. (B) Consumption of alcoholic liquor by persons under 21. It shall be unlawful for any person under 21 years of age to consume alcoholic liquor. (C) Exception. The possession and dispensing, or consumption by a person under 21 years of age of alcoholic liquor in the performance of a religious service or ceremony, or the consumption by a person under 21 years of age under the direct supervision and approval of the parents or parent or those persons standing in loco parentis of such person under 21 years of age in the privacy of a home, is not prohibited under this section.

Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: 2025 S-1: Supplement contains: Local legislation current through Ord. 2024-12-A, passed 12-17-2024; and State legislation current through 2024 Illinois Legislative Service, Pamphlet #6).

Full Breakdown

02(B) separately bars anyone under 21 from consuming alcoholic liquor. 02(E) limits enforcement to duly appointed and authorized peace officers, so a code enforcement officer or private citizen cannot sign the complaint. This sits in chapter 130's general-offenses provisions, distinct from the separate liquor-licensing chapter 110 rules that govern bars and package stores; it is the county's baseline rule against minors possessing or drinking alcohol, not a location-based open-container ban aimed at adults in parks or on sidewalks, and no such adult open-container ordinance appears elsewhere in this code.

Violations & Fines

§ 130.99(C) makes a § 130.02 violation a citation payable at the Circuit Clerk's office: $50 for a first violation, and at least $75 for each violation after that. In lieu of paying a first-offense fine, a person who pleads or is found guilty may instead elect, at his or her own expense, to attend an alcohol prevention class approved by the court.

Frequently Asked Questions

Is it illegal for someone under 21 to just possess alcohol in Rock Island County, even without drinking it?
Yes. § 130.02(A) separately bans purchasing, accepting delivery of, or simply possessing alcoholic liquor if you are under 21, regardless of whether you drink it. § 130.02(B) then bans consumption as its own separate violation.
Are there any exceptions to the county's underage alcohol ban?
Two. § 130.02(C) exempts alcohol used in a religious service or ceremony, and it exempts consumption by a minor at home when directly supervised and approved by a parent or a person standing in loco parentis. Outside those two situations, the ban applies.
What does a first violation of the underage alcohol law cost?
A $50 citation payable at the Circuit Clerk's office under § 130.99(C). A person can instead ask to attend a court-approved alcohol prevention class at their own expense in lieu of that first fine; every violation after the first carries at least a $75 fine with no class option.
Does the county have a general public open-container law for adults?
Not in the general offenses chapter reviewed here. § 130.02 is written specifically for people under 21; the county's other alcohol rules, such as § 110.077's ban on carrying open containers away from licensed premises, are tied to licensed establishments rather than public places generally.
