Outdoor music must comply with BCC 9.18 limits. Special events with amplified sound require a noise variance from the City Clerk and typically must end by 10 PM in Bellevue.
Outdoor music at private residences and businesses is subject to the same BCC 9.18 rules as other noise sources. Clearly audible music across a property line or 75 feet from the source violates BCC 9.18.040 regardless of time. Commercial venues with outdoor patios must ensure sound at residential property lines stays under 57 dBA day and 47 dBA night. Special events with outdoor amplified sound such as the Bellevue Downtown Association Live at Lunch, Arts Fair, or weekend concerts in Downtown Park require a Special Event Permit, which includes a noise variance approval by the City. Permitted events typically must end by 10 PM, use directional speakers pointed away from residential neighbors, and follow a posted public notice. Bellevue parks rental agreements restrict amplified sound in most neighborhood parks; amplified performances are limited to specific venues. Private parties with DJs or live bands may qualify for a one-time noise variance through the City Clerk.
Unpermitted amplified outdoor music: noise disturbance citation. Permit violations: permit suspension and future event denial. Fines escalate with repeat offenses.
