Industrial and commercial noise is capped by New Jersey's Noise Control Act, enforced locally, not by Morris County. Sound from a facility may not exceed 65 dBA (day) or 50 dBA (night) at a residential property line.
Morris County does not set industrial-noise limits. N.J.A.C. 7:29-1.2 directly governs sound from any industrial, commercial, public-service or community-service facility. Measured at a residential property line, it may not exceed 65 dBA from 7:00 a.m. to 10:00 p.m. or 50 dBA from 10:00 p.m. to 7:00 a.m., with an 80 dBA cap on impulsive sound and detailed octave-band limits. Enforcement runs through the state-certified municipal noise-control officer using N.J.A.C. 7:29-2 test procedures; NJDEP also enforces. Morris County towns hosting industrial and commercial zones (Parsippany, Mount Olive, Rockaway) apply these same figures through their local ordinances.
Violations are enforced by certified noise officers and NJDEP under N.J.A.C. 7:29-1.7, with penalties under the Noise Control Act and local ordinance fines.
