San Jose, CA Noise Ordinances: Outdoor Music (2026)

San Jose treats outdoor amplified music as a regulated noise source. Private residential gatherings are allowed but must respect the 55 dBA daytime and 50 dBA nighttime thresholds measured at neighboring property lines. After 10:00 PM, amplified music that disturbs any reasonable person of normal sensitivity is prohibited, regardless of decibel reading. Commercial venues such as restaurants with patios, breweries in the SoFA district, and event spaces in Santana Row need an Entertainment Permit if they host regular live or amplified music. One-off events exceeding normal limits require a Special Events Permit, which includes a noise management plan, neighbor notification, and a defined end time (typically 10:00 PM weekdays, 11:00 PM weekends). Music at public parks requires a Parks Special Use Permit. Wedding receptions at backyard venues and homes in Willow Glen and Rose Garden neighborhoods frequently generate complaints, and Code Enforcement responds to 311 reports. Repeat violations at the same address can trigger administrative hearings and fines. DJs and bands are expected to lower volumes at the permit end time; after-hours unpermitted amplified music is a common citation trigger.
