San Bernardino County treats loud and unruly gatherings as a public nuisance, and the Sheriff can bill responsible parties for repeat response calls under the County Code.
County nuisance and noise rules prohibit gatherings that disturb neighbors with amplified music, fights, public drunkenness, or excessive vehicle traffic. After a first warning, the Sheriff may post a notice and bill the host or property owner for the cost of follow-up responses within 12 months at the same address. Hosts also face civil and criminal exposure under California Business and Professions Code section 25658 if minors are served alcohol, and STR-specific rules apply in mountain and desert communities.
Repeat loud-party responses can produce cost-recovery bills, citations, and STR permit revocation in regulated communities.
