Boulder's Unruly Gathering ordinance under BRC §5-9 lets police cite hosts and tenants for repeat loud parties near CU. Property owners face escalating penalties, including possible nuisance abatement on chronic offender properties.
Boulder Revised Code chapter 5-9 (Unruly Gathering) authorizes Boulder Police to declare a gathering unruly when noise, intoxication, fighting, or property damage threatens public peace, especially in CU-adjacent neighborhoods like The Hill. Officers may issue summonses to hosts, tenants, and property owners. Repeat offenses within twelve months at the same address escalate fines and trigger Boulder Code Enforcement nuisance review. Landlords receive written notice and may face license action for failing to address repeat violations. The ordinance complements quiet-hours rules and addresses the alcohol-fueled gatherings that often follow CU football, basketball, and end-of-semester events.
First offense fines run several hundred dollars, with second and third offenses escalating into the thousands. Property owners may face nuisance enforcement, summary abatement, and attorney fee awards.
