Amplified music rules in Rialto, CA — also called sound permit, PA system, or live music ordinances — set decibel limits, time-of-day restrictions, and when permits are required.
Rialto Municipal Code Section 9.50.030(A)(4) bans music or sound amplification equipment that is plainly audible across property lines, through shared walls, at 50 feet from 8:00 a.m. to 10:00 p.m., or at 25 feet from 10:00 p.m. to 8:00 a.m.
Rialto uses a plainly-audible test rather than decibel meters: an officer only needs to detect the sound with unaided hearing, and feeling the rhythmic bass of music is enough (Section 9.50.020 definition). Section 9.50.030(A)(4) prohibits personal or commercial music equipment plainly audible across property boundaries, through partitions between residences, at 50 feet between 8:00 a.m. and 10:00 p.m., or at 25 feet between 10:00 p.m. and 8:00 a.m. Officers first issue a written abatement notice; a second violation within 72 hours allows confiscation and impoundment of the amplifying components (Sections 9.50.030(D)-(E)). City-authorized outdoor gatherings, dances, shows, and entertainment events are exempt under Section 9.50.060.
An infraction and public nuisance under Section 9.50.030(B). Penalties include citations, fines of $250 to $1,000 per Section 9.50.130, confiscation of speakers or amplifiers after a repeat violation within 72 hours, and second-response cost recovery under Section 9.50.090.
