Hosts of loud, unruly parties where alcohol reaches underage guests face a $1,000 civil penalty plus the cost of police, fire and other emergency response.

City-specific rules exist: Ventura, Simi Valley, Thousand Oaks, Camarillo, Moorpark, and Oxnard have their own loud party ordinance rules that differ from Ventura County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Such a violation subjects any and all responsible persons to a civil money penalty of one thousand dollars ($1,000.00) in addition to any recovery of response costs that might be imposed under Section 6113-5 of this article.

Violations of this section shall be noticed by citation, issued by the Sheriff, to any and all responsible persons identified by the Sheriff within thirty (30) days of the loud or unruly gathering at a residence or other private property at which service to, or consumption of alcohol or alcoholic beverages by, underage persons occurs. The citation shall also give notice of the right to request an administrative hearing to challenge the validity of the citation, the time for requesting that hearing and the warning relating to the recovery of response costs for subsequent citations under this chapter as described under Section 6113-5 of this article.

In the event that a loud or unruly gathering at a residence or other private property at which service to, or consumption of alcohol or alcoholic beverages by, underage persons occurs is hosted by a juvenile, then the parents or guardians of that juvenile will be jointly and severally liable for any penalties and response costs incurred pursuant to the ordinance codified in this chapter.

Full Breakdown

Under the Social Host Ordinance, any owner, tenant or organizer responsible for a loud or unruly gathering at a residence where alcohol is served to or consumed by anyone under 21 is strictly liable. The Sheriff can cite each responsible person within 30 days for a $1,000 civil penalty, and repeat responses within 12 months trigger recovery of the County's law-enforcement, fire and emergency response costs, which can become a property lien if unpaid.

Violations & Fines

A cited responsible person owes a $1,000 civil penalty per violation; a hosting juvenile's parents share liability, and unpaid response-cost bills become a lien against the property.

Frequently Asked Questions

Do I have to be home for the party to be liable?
No. Anyone with a right of possession of the property, owner, tenant, or the person who organized the gathering, can be held a 'responsible person' even if absent.
What if my teenager throws the party?
Parents or guardians of a hosting minor are jointly and severally liable for the $1,000 penalty and any recoverable response costs.
