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

Sec. 24-65, adopted by Ord. No. 18303 in October 2025, defines a nuisance gathering as ten or more persons where at least two of 15 qualifying offenses occur, including underage alcohol or cannabis possession, assault, battery, mob action, vandalism, criminal trespass, disorderly conduct, discharging firearms, obstructing a public way, illegal parking or unlawful weapon possession. A 'nuisance participant' includes the property owner who permits the gathering, the person who organizes, promotes, sponsors or hosts it, anyone present who commits a qualifying offense, and anyone present who ignores a police dispersal order.

Once an officer determines a gathering qualifies, the officer may order everyone to disperse immediately, subject to first notifying and getting approval from a police supervisor. 00. Beyond the fine, every nuisance participant is jointly and severally liable for the city's public costs, meaning police, fire and public works response, cleanup, property repair and injury-related costs, and the city can also seek disgorgement of any profit a host received from the gathering. If the participant is a minor, the city may recover costs from a parent or guardian under the Parental Responsibility Law.

A property owner or host avoids liability by showing they took reasonable steps to prevent or stop the gathering and fully cooperated with police, and a resident who peacefully complies with a dispersal order at their own home is not a nuisance participant.
