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

Division 4 of Part 2, Disorderly Conduct, in Chapter 2 of Article IV of the Arcadia Municipal Code is titled Disorderly Party, Enforcement Fee. It was added by Ord. 1901 adopted 1-3-89 and works as a cost-recovery rule rather than a fine schedule.

The trigger in Section 4224.1 is a loud, unruly or disorderly party or assemblage where the senior ranking Police Officer at the scene determines there is a threat to the public peace, health, safety, or general public welfare. That officer notifies the owner of the premises, the person in lawful custody of the premises, or the person responsible for the assemblage. If the responsible person is a minor, the notice reaches the parents or guardians of that minor, who are jointly and severally liable for the cost of Police personnel on a second or subsequent response to the same location due to a continuation of the same conduct.

The first response and warning count as normal Police service at no charge. Personnel used on a second or subsequent response after the first warning are treated as being on special assignment, and the costs are beyond normal services. The costs of that special assignment include personnel and equipment costs, damage to City property, and injuries to City personnel.

Section 4224.2 repeats who pays: the owner of the premises, the person in lawful custody of the premises, or the person responsible for the assemblage, or the parents or guardians when that person is a minor, all jointly and severally liable. Under Section 4224.3 the Police Department transmits reports of subsequent response incidents to the Director of Finance, who calculates the fees and assesses them against the responsible parties. Section 4224.4 leaves any adjustment or procedural requirement needed to administer the division to a resolution of the City Council.

The division prints no dollar amount. The bill follows the actual cost of the second or later response.
