Elgin, IL Public Conduct: Loud Party Ordinance (2026)

020(A) for a person to permit, allow, or host an event or gathering at their residence, other private property, a public place, any premises under their control, or a conveyance, where an underage person has consumed illicit drugs, alcohol or alcoholic beverages, if the host knew or reasonably should have known of that consumption. 020(B) imposes an affirmative duty to take all reasonable steps to prevent underage consumption, and creates a rebuttable presumption of knowledge when the host was present at the time an underage person drank or used drugs, or when the host failed to take reasonable preventive steps regardless of presence.

030 exempts conduct involving alcohol at a religious ceremony, or exclusively between an underage person and their own parent or legal guardian, and shields a host who calls police to remove a noncompliant guest or terminate the gathering before anyone else complains. 040 sets the penalty at not less than $500 for each offense, plus 'response costs,' defined to include law enforcement, fire and other emergency personnel salaries, medical treatment for responders injured at the scene, and repair or use costs for damaged city equipment.

Each day a violation continues is a separate offense, and the fine does not preclude the city from also suspending or revoking a license or permit or seeking injunctive relief.
