Full Breakdown
24. The rule reaches any stereo, radio, musical instrument, phonograph, television or similar device that 'produces or reproduces sound' at a volume louder than needed for the people in the room, vehicle or place where it is playing, if it disturbs the peace, quiet and comfort of neighboring inhabitants. so that it is plainly audible inside an adjacent or neighboring residential unit, or audible at 50 feet from a non-residential building, is 'prima facie evidence of a violation' and shifts the burden to the operator.
030: a law enforcement officer, code enforcement officer, or other City Manager-designated official may cite based on unassisted hearing, after confirming the source with a direct line of sight when possible; the officer does not need to identify song titles, artists or lyrics to establish a violation. 040 allows a defense only for noise from causes genuinely beyond the operator's control that were diligently addressed. 010 and the noise is also declared a public nuisance the City Attorney may abate on Council direction. Liability is not limited to whoever pressed play: the property owner, tenant, lessee, manager or anyone lawfully in possession of the premises at the time the sound was emitted is jointly and severally responsible if they knew or should have known of the disturbance, though an absentee owner cannot be cited until first warned in writing and the noise recurs.
Violations & Fines
A first offense is charged as an infraction under Municipal Code § 1.12.010. The City Attorney may also pursue nuisance abatement on City Council direction. Both the person operating the equipment and the property owner, tenant, or manager in possession of the premises can be cited if they knew or should have known of the disturbance, unless an absentee owner has not yet been warned in writing.
