Gilbert, AZ Public Conduct: Loud Party Ordinance (2026)

Section 42-91 defines an "unruly gathering" as a party, gathering, or event on public or private property, including business property, that disturbs others' reasonable enjoyment of property, expressly including excessive noise "reasonably evaluated by a police officer and/or by a code enforcement officer as disturbing the peace and quiet enjoyment of people working or living in the vicinity," plus impeding traffic, obstructing sidewalks or streets, public drinking, illegal drug use, underage possession of alcohol or marijuana, fighting or violence, and littering. A "responsible person" includes an owner, landlord, or tenant, or the sponsor, host, or organizer, and if that person is a juvenile the term extends to the juvenile's parents or guardians.

Section 42-92 makes it unlawful for a responsible person to permit an unruly gathering, and separately unlawful for any person to engage in conduct causing a gathering to become unruly. A police officer may abate an unruly gathering under § 42-93 by any reasonable means, including citation or dispersing attendees. Section 42-94 limits owner/landlord/tenant liability: they are not liable unless they were present during the gathering, knew about it and took no reasonable action, or an unruly gathering already occurred on the property within the prior 180 days, and the exception doesn't apply if attendees obtained access through illegal entry or trespass.

00 for a first violation, escalating to a class one misdemeanor for a habitual offender who violates the division again within 18 months of a prior finding, plus liability for the town's reasonable response expenses, police, fire, rescue, public works, and EMS costs and staff salaries, excluding regulated ambulance charges.
