Summary
Lake County declares underage drinking and drug parties a nuisance; anyone who knowingly hosts or permits alcohol or illicit drugs at a social event faces fines up to $1,000 per violation.
It shall be unlawful for any parent or person to knowingly host, either on premises owned or controlled by the parent or person, or at any public place, or in any conveyance, a social event where the parent or person knows, or reasonably should know, that underage persons are in possession of, or are consuming, illicit drugs or alcoholic beverages.

Full Breakdown
Lake County Code §§ 131.15-131.17 declare social events where anyone under 21 possesses or consumes alcohol or illicit drugs a nuisance, and it is unlawful for a parent or person to knowingly host such an event -- on property they control, in a public place, or in a vehicle -- or to otherwise permit it. A host avoids liability by taking reasonable steps, such as confiscating car keys or calling police once aware, or ending the event. The Lake County Sheriff enforces the chapter through Circuit Court citation or administrative adjudication, as with the chapter's curfew and truancy sections, which reach unincorporated Lake County -- not cities like Waukegan, Highland Park, and Gurnee that run their own police and codes.
Violations & Fines
First offense: minimum $250 fine; second offense within 12 months: minimum $750; third or subsequent: flat $1,000; each 24-hour period is a separate offense, capped at $1,000 per violation.
