(Ord. No. 716, § 3(Exh. A), 5-9-2017)
9.10.040 - Liability for response costs.¶
A. Liability for Response Costs. If a law enforcement, fire, or other emergency response provider, responds to a loud or unruly gathering at a residence or other private property within the city, within twelve months of a warning given to a responsible person regarding a loud or unruly gathering at the same location, all responsible persons will be jointly and severally liable, in addition to any fine imposed under Section 9.10.030 above, for the response costs for that response and all subsequent responses during the twelve-month period. If a responsible person for the gathering is a minor, then the parents or guardians of that minor and the minor will be jointly and severally liable for the response costs. To incur liability for response costs imposed by this chapter, the responsible person for the loud or unruly gathering need not be present at such gathering resulting in the response giving rise to the imposition of response costs. This chapter imposes vicarious as well as direct liability upon a responsible person.
B. Warning.
- Prior to imposing any liability under subsection (A), when a law enforcement, fire or other emergency response provider makes an initial response to a loud or unruly gathering at a residence or other private property within the city, a written warning must be provided to any responsible person for the gathering that:
a. A loud or unruly gathering has been found to exist; and
b. Any responsible person may be charged for the response costs incurred for subsequent responses to a loud or unruly gathering at the residence or other private property within a twelve-month period from the date of the warning.
If a responsible person cannot be identified at the scene, the official may subsequently return to the residence or other private property and issue the warning to a then-present responsible person.
If a written warning is not provided to a responsible person who identifies himself or herself as an owner of the property, then a copy of the warning must be sent within thirty days of the initial response by first-class or certified mail to the owner of the residence or other private property, as identified on the last equalized assessment roll of the Los Angeles County Assessor.
A copy of the warning may also be given to any other known responsible person who does not reside at the residence or other private property in question by first-class or certified mail within thirty days of the initial response.

B. Notice of the response costs for which the responsible person is liable will be mailed by certified mail within forty-five days of the response giving rise to such costs. The notice must contain the following information:
