Summary
Chandler makes it unlawful to host or attend a gathering whose noise disturbs neighbors under City Code § 11-10.3, and a police officer may order everyone but the owners or tenants to disperse. A companion "unruly gathering" ordinance at § 11-16 holds any responsible person, including a host who isn't even present, liable when a party also involves minor drinking, illegal drugs or violence.
A. Prohibition of parties that disturb the peace. No person shall knowingly congregate because of, or participate in, any party or gathering of two (2) or more people from which noise emanates of sufficient volume or of such nature to reasonably disturb the peace, quiet, or repose of other persons. B. Authority to disperse noisy party. A Police Officer may order all persons present other than the owners or tenants of the building or place to immediately disperse. It shall be unlawful for any person to refuse to leave after being ordered to do so by a Police Officer. C. Owner or other tenant responsibility in abatement of disturbance. It shall be unlawful for any owner or tenant of the building or place who has knowledge of the disturbance to fail or refuse to immediately abate said disturbance.

Full Breakdown
3 prohibits knowingly congregating in, or participating in, a party or gathering of two or more people from which noise emanates loudly enough to disturb the peace, quiet or repose of others. An officer responding to such a party can order everyone present except the owners or tenants to leave immediately, and refusing that order is itself unlawful. Separately, an owner or tenant who knows of the disturbance and fails to abate it is in violation. Section 11-16, added by Ordinance 4642 and amended in 2024, goes further: it defines an "unruly gathering" as one that threatens public peace, health, safety or welfare through excessive noise, blocked traffic, illegal drugs, underage drinking, fighting or littering, and makes any "responsible person", an attendee, host, sponsor, tenant, or an owner previously notified of a gathering at the same address within 180 days, liable even if not present when police respond.
A juvenile responsible person's parents or guardians are also swept in. Police may abate an unruly gathering by citation, arrest, or dispersal of remaining participants, and a non-resident who refuses a lawful dispersal order can be cited as a responsible person in their own right.
Violations & Fines
A violation of § 11-10.3 is a misdemeanor under § 11-10.4, punishable per Chapter 1's general penalties. An unruly gathering under § 11-16.5 is normally only a civil infraction under § 1-8.7, but it becomes a Class 1 misdemeanor if the same responsible person is found responsible again within 18 months, or immediately if minors possessed or consumed alcohol, illegal drugs were involved, a felony act occurred, or a physical altercation caused injury.
