Santa Clarita, CA Public Conduct: Loud Party Ordinance (2026)

092 defines a loud party as a gathering of two or more people on private property that a law enforcement officer at the scene determines is disruptive to the peace, health, safety, or welfare of the area because of crowd size, noise, unruly behavior, traffic congestion, illegally parked vehicles blocking access, or property destruction. The "responsible person" who can be cited is the property owner, the person in charge of the premises, or the person who organized the gathering; an absentee property owner is only liable if they knew, planned, or reasonably should have known about the party, but that exception does not protect a parent or guardian of a minor host.

Subsection (A)(2) lists five prima facie triggers: noise audible fifty feet from the source, wild or unruly behavior disruptive to neighbors, a crowd size that violates the fire code, illegally parked or traffic-blocking vehicles, and property destruction. 094, they may order attendees to disperse, vacate, and shut off radios, televisions, and amplifiers; refusing that order is a separate offense from the underlying loud-party violation, and anyone not living at the address must leave immediately. 096 adds an escalating cost: after a first response, officers issue a written reimbursement notice, and if deputies must return to the same address for another violation within one calendar year, every responsible person is jointly and severally liable for the City's actual law-enforcement costs, any property damage, and any injuries to personnel from that second or later response. 110 unless the City designates the offense an infraction, and each day a violation continues is a separate offense.
