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

Article X of Chapter 25 defines a "nuisance party" as an assembly for a social activity or special occasion that substantially disturbs the quiet enjoyment of private or public property, including excessive noise or traffic, obstruction of streets, public drunkenness, service of alcohol to minors, fights, and litter (Sec. 25-111). When a Glendale police officer responds and finds a threat to public peace, health, safety or welfare, the officer issues written notice to the responsible person (any attendee, host, tenant or organizer) and, if the owner is not present, mails a copy to the owner at the address on the Maricopa County property tax assessment records (Sec.

25-112(a)). The responsible person is charged a police service fee for the response, and for a second or subsequent response within 180 days the owner is also billed. Sec. 25-115 sets the fee schedule at $500 for a first response, $1,250 for a second, and $2,500 for a third and each subsequent response, the same schedule applying to "unlawful gatherings" where alcohol reaches a minor or illegal drugs are present. An owner escapes the first-response fee only if they were absent and had no knowledge of the party, per Sec.

25-114(c). Fees are joint and several against every responsible person and, if a responsible person is a juvenile, against that juvenile's parents or guardians (Sec. 25-114(b)); unpaid fees are delinquent after 30 days of billing. Beyond the fee, Sec. 25-116 makes it a separate civil offense for a responsible person to permit a nuisance party or unlawful gathering, and Sec. 25-117 makes it a civil offense for an owner to permit one after having already been notified of a prior incident within 180 days at the same premises. Sec. 25-118 preserves the city's ability to pursue concurrent criminal prosecution for the same conduct.
