Full Breakdown
Table 2A of Moorpark's noise chapter sets flat decibel ceilings for equipment used on business properties, separate from the zone-based ambient limits in Table 4. Mobile equipment run on a nonscheduled, short-term basis may not exceed 75 dB(A), measured daily including Sundays and holidays, at any hour. Stationary equipment operated on a repetitive, long-term schedule, pumps, compressors, generators, and similar commercial or light-industrial machinery, is capped at 65 dB(A), also at any hour. Exceeding these levels violates § 17.53.070's prohibited-acts provisions, enforced by the community development director as noise control officer.
Violations & Fines
Running business-property equipment above the Table 2A caps is a misdemeanor/infraction under Chapter 1.12; each day of the violation is a separate offense.
