Amplified music rules in San Jose, CA — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Santa Clara County regulates amplified music through its noise ordinance with decibel limits and quiet hours. Outdoor amplified sound generally requires a permit and must meet property-line limits.
Amplified music in unincorporated Santa Clara County is regulated under the County Noise Ordinance (Division B11 of the County Code). The ordinance establishes exterior noise limits measured at the property line of the receiving parcel, typically 55 dBA daytime and 45 dBA nighttime in residential zones, with nighttime hours running from 10:00 PM to 7:00 AM. Amplified music that exceeds these limits or that is plainly audible from 50 feet away in residential areas may be cited as a public nuisance. Commercial venues hosting outdoor amplified entertainment need an administrative permit from the Planning Office and may require CEQA review for events exceeding threshold attendance. Wedding venues in the foothills (Los Gatos hills, west of Saratoga) commonly operate under conditional use permits that cap amplified music at 10:00 PM. Sheriff deputies respond to noise complaints and can issue infractions.
