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

Placentia regulates parties through two separate provisions. Chapter 10.68 targets admission charge parties in residential zones. Section 10.68.010 defines a party as 12 or more persons meeting together for social, recreational or amusement purposes, and an admission charge as the transfer of a tangible benefit, monetary or otherwise, required as a condition of admittance. Customary courtesies, donations for political, charitable, community service or religious purposes, and clearly noncommercial activity such as gifts from guests and voluntary sharing of expenses for meals are not admission charges. Section 10.68.020 makes it unlawful to require any admission charge, by implication or expressly, for any party in any residential zone.

Noise is handled by Chapter 23.76, and § 23.76.050(b) is the host-liability clause. It is unlawful to create any noise, or to allow the creation of any noise on property owned, leased, occupied or otherwise controlled by the person, that exceeds the noise standards on another property for a cumulative period of more than thirty minutes in any hour, with shorter allowances at higher levels. Residential property is held to 55 dB(A) from 7:00 a.m. to 10:00 p.m. and 50 dB(A) from 10:00 p.m. to 7:00 a.m., and where the noise consists entirely of music, speech, impact noise or simple tone noise each level is reduced by 5 dB(A). Inside a neighbor's dwelling unit, § 23.76.060 sets 55 dB(A) from 7:00 a.m. to 10:00 p.m. and 45 dB(A) from 10:00 p.m. to 7:00 a.m., with the same 5 dB(A) reduction for music and speech. The amplified sound rule in § 10.32.030 also applies to loudspeakers at a party.
