Summary
Irvine Municipal Code § 4-11-502 lets a police officer who responds to a loud or unruly gathering issue a written warning notice; any further police response to the same address within 30 days becomes a billable 'special security assignment.' Section 4-11-501 defines 'unruly or loud conduct' broadly, from street-blocking crowds to public drunkenness, assault or vandalism.
A.When any police officer responds to any party, gathering or event due to loud or unruly conduct, the police officer may issue a written notice to each responsible person or host. That notice shall state that each subsequent response to that same location or address within a 30-day period shall be deemed a special security assignment rendered to provide security and order on behalf of the party, gathering or event and that each responsible person or host may be liable for a police services fee, as defined in this chapter.

Full Breakdown
Chapter 5 of Division 11 addresses loud parties and, separately, hosts who let underage guests drink. 3 layers administrative fines, set by City Council resolution and escalating for a second or third violation within 12 months, on top of the police services fee, and holds a minor host's parent or guardian liable for those fines. A host disputing an invoice has 15 calendar days from the mailing date to request an administrative hearing before the Director of Public Safety under § 4-11-505, with judicial review available afterward.
Violations & Fines
A second police response to loud or unruly conduct at the same address within 30 days of a first warning triggers a police services fee of up to $1,000 under §§ 4-11-501–503, owed jointly by every previously warned host. Separately, knowingly allowing underage drinking at the gathering is unlawful under § 4-11-503.1 regardless of any prior warning, and each violation can draw an escalating administrative fine set by City Council resolution under § 4-11-503.3, with a minor host's parent or guardian personally liable.
