Amplified music rules in San Diego County, CA — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Amplified music in unincorporated San Diego County must comply with the noise ordinance decibel limits under Section 36.404. Residential zones: 50 dBA daytime, 45 dBA nighttime at the property line. Amplified sound for events may require a special permit from the County.
The County noise ordinance applies to all amplified sound including music, loudspeakers, PA systems, and DJ equipment. Sound levels are measured at the property line of the affected property. Residential zones have a 50 dBA limit during the day (7 AM–10 PM) and 45 dBA at night (10 PM–7 AM). Amplified music that exceeds these limits is a violation. Special events in unincorporated areas requiring amplified sound may need permits from the County Department of Parks and Recreation or Planning & Development Services, depending on the location.
