Full Breakdown
Moorpark's noise ordinance singles out places of public entertainment, bars, nightclubs, venues with live music or DJs, under the chapter's list of prohibited acts. Loudspeakers, musical instruments, or other sound sources may run above typical limits, but once the level exceeds 95 dB(A) on the sound meter's slow response at any point normally occupied by a customer, the operator must post a conspicuous, legible sign reading 'Warning: Sound Levels Within May Cause Hearing Impairment.' The community development director, acting as noise control officer, enforces the requirement alongside the rest of Chapter 17.53's noise-disturbance rules.
Violations & Fines
Operating without the required warning sign above 95 dB(A) is a misdemeanor/infraction under Chapter 1.12; each day of continued violation counts as a separate offense.
