13.48.010 Findings and purpose.

This chapter is enacted for the following public purposes among others:

A. Due to inadequate supervision, some large gatherings of people, such as parties, frequently become loud and unruly to the point that they constitute a threat to the peace, health, safety, or general welfare of the public as a result of conduct such as one or more of the following: excessive noise, excessive traffic, obstruction of public streets or crowds who have spilled over into public streets, public drunkenness, the service of alcohol to minors, fights, disturbances of the peace, and litter.

B. The City of Berkeley (hereafter "City") is required to make multiple responses to such unruly gatherings in order to restore and maintain the peace and protect public safety. Such gatherings are a burden on scarce City resources and can result in police responses to regular and emergency calls being delayed and police protection to the rest of the City being reduced.

C. In order to discourage the occurrence of repeated loud and unruly gatherings, the persons responsible for the public nuisance created by these gatherings should be fined. (Ord. 6182-NS § 1, 1993)

A. Posting of Premises.

13.48.040 Persons liable for a subsequent response to a gathering constituting a public nuisance.

If the City is required to intervene as to a gathering constituting a public nuisance on the same premises more than once in any 120-day period, including a second intervention during the same day or night as the first intervention, the following persons shall be jointly and severally liable for civil penalties as set forth in Sections 13.48.050 below, in addition to liability for any injuries to City personnel or damage to City property.

A. The person or persons who own the premises where the gathering constituting a public nuisance took place if any of the following are the case: (1) said owner resides on or adjacent to the premises, (2) said owner was present when the Notice described in Exhibit A was first posted, or (3) the Notice described in Exhibit A was mailed to said owner and 14 days have elapsed since the date of said mailing. For purposes of this subsection, where a gathering takes place within the confines of a single unit in a building owned by a housing cooperative, the owner of the property shall be deemed to be the owner of the single unit and not the members of the housing cooperative in general. Where the gathering took place in the common area of a building owned by a housing cooperative, only the members of the cooperative owning units in the building where the gathering took place shall be deemed the owners of the property for purposes of this subsection. Other members of the housing cooperative may still be liable if they fall within the categories of person made liable by Section 13.48.040, subsections B., C., or D., below.

B. The person or persons residing on or otherwise in control of the property where such gathering took place.

C. The person or persons who organized or sponsored such gathering.

D. All persons attending such gathering who engaged in any activity resulting in the public nuisance.

E. Nothing in this section shall be construed to impose liability on the resident or owners of the premises or sponsor of the gathering, for the conduct of persons who are present without the express or implied consent of the resident or sponsor, as long as the resident and sponsor have taken all steps reasonably necessary to exclude such uninvited participants from the premises. Where an invited guest engages in conduct which the sponsor or resident could not reasonably foresee and the conduct is an isolated instance of a guest at the event violating the law which the sponsor is unable to reasonably control without the intervention of the police, the unlawful conduct of the individual guest shall not be attributable to the sponsor, owner, or resident for the purposes of determining whether the event constitutes a public nuisance under this section.

F. There shall be no liability for civil penalties under this chapter for a subsequent intervention during the same day or night as the prior intervention, unless a reasonable time has been provided to abate the public nuisance, taking into account the size of the gathering, the time of day, and other relevant factors.

G. There shall be no liability for civil penalties under this chapter for a second response during the same day or night as the first response when a person who would otherwise be liable under subdivision (A) seeks assistance from the Police Department to abate a public nuisance under this Chapter, and the person cooperates fully with the police while taking reasonable action to abate the public nuisance.

H. If the City is required to intervene at a gathering constituting a public nuisance on the same premises more than once in any 120-day period, excluding a second intervention during the same day or night as the first intervention, the 120-day period shall be extended by another 120 days from the date of the second intervention. (Ord. 6974-NS § 2, 2007; Ord. 6182-NS § 4, 1993)

B. The City shall bill all persons liable for the penalties by sending an administrative citation issued pursuant to Chapter 1.28 along with a letter in substantially the form attached hereto as Exhibit "B" by mail. Payment of the penalties shall be due within thirty (30) days of the date the administrative citation is issued in accordance with Section 1.28.050.A. If full payment is not received within the required time for payment of the administrative citation, the bill will be delinquent, and all persons liable for the penalties shall be charged interest at the maximum legal rate from the date the payment period expires and a further civil penalty in the amount of one hundred dollars ($100.00).
