San Bernardino County, CA Noise Ordinances: Amplified Music & Events (2026)

Amplified music in unincorporated San Bernardino County is regulated mainly by County Code Section 24.0705 (Disturbing, Excessive or Offensive Noise), part of the County's Noise Abatement and Control chapter. It is unlawful to make, cause, or allow noise that is disturbing, excessive, or offensive to a reasonable person, and the section expressly lists examples including yelling, shouting, hooting, whistling, singing, playing a musical instrument, and emitting or transmitting loud music or noise from any audio equipment or sound-amplifying equipment. A violation generally must be supported by declarations from two neighboring inhabitants, unless an enforcement officer personally determines after investigating that the source is disturbing, excessive, or offensive. For ongoing amplified sound at a fixed location, the Development Code stationary-source standards in Section 83.01.080 also apply (55 dB(A) Leq day / 45 dB(A) Leq night at a residence, Table 5). Short-term rentals carry an additional, specific rule: County Code Section 84.28.070(h) makes it unlawful for an owner, renter, occupant, or guest to make or allow loud, excessive, or intrusive noise that disturbs the peace, expressly including loud music from sound-making or sound-amplifying devices, and the County operates an Outdoor Noise Monitoring System for permitted STRs.
