Police Code Section 49 lets SFPD declare a gathering loud and unruly, post a warning, and impose response-cost fees on hosts and property owners for any return call within 12 hours.
Police Code Section 49, the Loud or Unruly Gathering ordinance, authorizes SFPD to respond to noise, public-disturbance, or alcohol-related complaints at private residences. On the first response, officers may order the gathering ended and post a written warning citing the address. If officers must return within 12 hours due to continued noise or disturbance, the city may bill the host, tenant, and property owner jointly for actual response costs (officer time, vehicles, and overhead). Persistent properties can be designated chronic nuisances under Article 11 of the Police Code, triggering abatement actions. SFPD coordinates with the Entertainment Commission for permitted events, which follow a separate process.
Hosting a second loud-party response within 12 hours triggers joint billing of hosts and owners for SFPD costs, plus possible chronic nuisance designation for repeat addresses.
