Full Breakdown
The General Plan Noise Element (Standard N-S7) sets maximum permissible short-term noise levels by zoning classification. Amplified music at parties, weddings, restaurants, or commercial events is held to those Lmax limits unless an exception applies. The Element specifically lists 'Temporary events in conformance with an approved Conditional Use Permit' as one of five categories exempt from N-S7 limits. Policy N-P4 directs the County to 'Protect persons from existing or future excessive levels of noise which interfere with sleep, communication, relaxation, health or legally permitted use of property.' The Element also notes that 'Noise level above 66 dBA requires raised voices to be heard at a distance of three feet' and 'Indoor noise levels between 50 and 60 dBA can disturb sleep,' which is why nighttime residential Lmax is capped at 60 dBA. State law (Penal Code 415) provides an additional misdemeanor remedy for willful loud and unreasonable noise.
Violations & Fines
Amplified music exceeding the Lmax for the receiving property's zone may be cited under General Plan standards. Operating without a required Conditional Use Permit for a temporary event compounds the violation. Penal Code Section 415(2) violation is a misdemeanor (up to 90 days/$400).
