Palmdale, CA Public Conduct: Loud Party Ordinance (2026)

PMC § 9.18.030(A) defines a "loud party" as a gathering of two or more people on private property that law enforcement personnel determine, at the scene, is disruptive to public peace, health, safety, or welfare because of crowd size, noise, disturbances, unruly behavior, traffic congestion, illegally parked vehicles blocking access, or property destruction. Subsection (B) makes it unlawful for a "responsible person," the property owner, whoever is in charge of the premises, or whoever organized the event, to organize, cause, or permit one; if that responsible person is a minor, the minor's parents or guardians are also responsible persons even if they weren't present. An absentee property owner escapes liability only if they didn't know, and had no reason to know, the party was happening or planned.

Five prima facie tests make enforcement concrete under § 9.18.030(B)(2): noise audible from 50 feet, wild or unruly behavior disruptive to neighbors, a crowd large enough to violate the fire code, illegally parked or access-blocking vehicles, or property destruction by attendees. Once police declare a gathering a public nuisance, § 9.18.030(F) requires everyone not living at the address to leave immediately on order, and refusing a law enforcement order to disperse or shut off music under subsection (E) is a separate, additional offense from throwing the party itself.
