Construction hours in Morris County, NJ — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Construction-hour limits are set by your Morris County town, not the county. Local codes typically allow construction and demolition roughly 7 a.m. to evening on weekdays, with tighter weekend and holiday starts. The state 65/50 dBA caps back them up.
Morris County does not restrict construction hours; New Jersey municipalities do, under the Municipal Land Use Law and their local noise ordinances. Typical Morris County town ordinances (patterned on the NJ Model Noise Ordinance) confine construction, demolition and related motorized equipment to daytime windows beginning around 7:00 a.m., with later starts on weekends and federal holidays and no work overnight. All construction equipment must be operated with a functioning muffler. The overarching backstop is N.J.A.C. 7:29, which limits continuous sound at a residential property line to 65 dBA by day and 50 dBA at night. Confirm exact start/stop times in your municipality's noise chapter.
Local code officers issue municipal-court summonses under the town noise ordinance; fines are set per municipality and typically increase for repeat construction-hour violations.
