Social Host Ordinance

  • Print

Social Host refers to adults who host parties where alcohol is served on property that they control. Through social host liability laws, adults can be held responsible for these parties if underage people are served, regardless of who furnishes the alcohol. Teen parties are a primary setting for underage drinking for both high school and college students; to include high consumption of alcohol and binge drinking.

The Social Host Ordinance expands the ability of the Police Department to address threats to the public health, safety and welfare by imposing accountability in two related areas:

The first component of the ordinance addresses accountability for gatherings where alcohol, marijuana or other controlled substances are served to, consumed by, or in possession of underage persons.

The second component of the ordinance creates accountability for loud and unruly gatherings on private property which create a public nuisance due to excessive noise, excessive traffic, public drunkenness, violence, disturbance of the peace, or other disturbances to public health, safety and welfare.

For more information please read the attached Social Host Ordinance.
