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

Under §9.29.020, an 'event' is any party or gathering on private property, regardless of headcount, that draws a police response because of an alleged violation of the Corona Municipal Code or of state or federal law, including Penal Code §§ 407, 415, or 416. 'Person responsible for the event' reaches beyond the host: it covers the property's owner of record, whoever is in charge of the premises, whoever authorized its use, whoever organized the party, and anyone the responding officer believes is causing or maintaining the gathering as a nuisance.

Section 9.29.030 requires the first officer on scene to leave a written warning with a responsible person, or post it on the front door if no one can be found. The warning must record the date, time and location of the response, explain why the gathering qualifies as an 'event,' and spell out that a repeat call can bring an administrative citation. That warning doubles as a notice of violation under §1.08.130 for every possible responsible person, whether or not each one actually saw it.

If officers return to the same address within three months of that warning, or within three months of an earlier subsequent response, §9.29.040 lets the officer issue an administrative citation under §1.08.110 et seq. to each responsible person: $100 for a first subsequent response, $250 for a second, and $500 for a third and every one after that. A person responsible for a qualifying event is guilty of an infraction regardless of whether a citation is actually written, and Corona can pursue criminal penalties on top of the administrative fine. Citations mailed to an absentee property owner go by certified mail to the address on the Riverside County tax assessor's roll.
