Summary
Dublin's Social Host Ordinance makes it an infraction to permit, allow, or host a loud or unruly gathering at a residence or on private property if a minor consumes alcohol there and the host knew or reasonably should have known. Presence at the gathering when a minor drinks creates a rebuttable presumption of knowledge under Section 5.94.030.
Except as permitted by Article 1, Section 4, of the California Constitution, it is unlawful for any person to permit, allow, or host a loud or unruly gathering at his or her place of residence, or on other private property or rented public property, if such person either knows or reasonably should have known that a minor has consumed an alcoholic beverage. ... Any person who permits, allows, or hosts a loud or unruly gathering shall be rebuttably presumed to have actual or constructive knowledge that minors have consumed alcoholic beverages if such person is present at the premises of the gathering at the time any minor consumes an alcoholic beverage.

Full Breakdown
94, adopted by Ord. 7-09 and Ord. 8-09, defines a 'loud or unruly gathering' as two or more persons at a residence, private property, or rented public property where loud or unruly conduct occurs and a minor consumes alcohol, including excessive noise, excessive traffic, street obstruction, assaults or fights, vandalism, or litter. 030 makes it unlawful for a social host, defined broadly as anyone who permits, allows, or hosts a gathering at a residence or other premises under their control, to allow such a gathering if they know or reasonably should have known a minor consumed alcohol.
030(C) creates a rebuttable presumption of knowledge if the host is present when a minor drinks. 050 requires the host to take 'reasonable steps' to prevent underage drinking, listing controlling access to alcohol, checking government-issued ID, and monitoring minors at the gathering; a host is not in violation if they call the Dublin Police Department to remove a noncompliant guest or end the gathering before anyone else complains, or if someone seeks emergency medical help. 040 exempts premises regulated by the state Department of Alcoholic Beverage Control. 080 subordinates the chapter to state and federal law.
Violations & Fines
Section 5.94.060 makes any violation of Chapter 5.94 an infraction, and it does not limit any other remedy or penalty the city may otherwise impose, so police can still pursue noise, nuisance, or state underage-drinking charges against attendees separately from the host's infraction citation.
