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

020 is a cost-recovery ordinance, not a noise-decibel rule. It applies once a large party or gathering has already drawn public safety personnel to the scene and that personnel determines the gathering threatens the public peace, health, safety, or general welfare. If officers or firefighters have to return for a second response after an initial warning to control that threat, the personnel used on that second response is treated as a special security assignment over and above the department's normal services, and the city can bill for it.

Liability is joint and several between the person in charge of the premises and the person responsible for the event; if either of them is a minor, the bill goes to that minor's parents or guardians instead. The costs the city can recover aren't limited to staff time: the section expressly allows the city to include minor damage to city property and injuries to city personnel in the bill. 020, the ordinance is aimed specifically at repeat calls to the same gathering. 070, use a similar minor-liability structure, charging costs to a minor's parent or guardian.
