Summary

Hackensack caps sound at the real property line under City Code § 112-7, which applies the decibel tables in Tables I through III to every listed source and receiving property. Impulsive sound, such as a bang or slam, cannot equal or exceed 80 decibels between 7:00 a.m. and 10:00 p.m., or occur more than three times an hour overnight before it is treated as continuous sound under the same tables.

§ 112-7. Maximum permissible sound levels. ... No person shall cause, suffer, allow, or permit the operation of any source of sound on any source property listed in § 112-3A above in such a manner as to create a sound level that equals or exceeds the sound level limits set forth in Tables I, II or III ... when measured at or within the real property line of any of the receiving properties listed in Tables I, II or III except as specified in § 112-6B. ... Impulsive sound. Between 7:00 a.m. and 10:00 p.m., impulsive sound shall not equal or exceed 80 decibels. Between 10:00 p.m. and 7:00 a.m., impulsive sound which occurs less than four times in any hour shall not equal or exceed 80 decibels. Impulsive sound which repeats four or more times in any hour shall be measured as continuous sound and shall meet the requirements as shown in Tables I and II.

Full Breakdown

Section 112-7 of Chapter 112 is the operative decibel cap for Hackensack: no person may operate a sound source in a way that equals or exceeds the sound level limits in Tables I, II or III, measured at or within the real property line of any receiving property listed in those tables. The tables, adopted as Attachment 1 to the chapter, set A-weighted decibel maximums that vary by the zoning category of both the source property and the receiving property, and by time of day, splitting daytime from nighttime hours; a nearby outdoor cafe permit even cross-references "Table I, Maximum Permissible A-Weighted Sound Levels When Measured Outdoors" when deciding whether patron speakers can run.

m. , but only if the impulsive sound occurs fewer than four times in an hour; once it repeats four or more times in an hour, the code stops treating it as impulsive and measures it as continuous sound against the ordinary Tables I and II limits instead, which are typically lower at night. 4-1983 standards, with indoor readings taken at least three feet from any wall, floor or ceiling.

Violations & Fines

Exceeding the Table I-III limits or the 80-decibel impulsive sound cap is enforced under § 112-11: a first, minor violation typically draws a notice of violation with up to 90 days to voluntarily correct it under the state Grace Period Law, while a nonminor or repeat violation draws a notice of penalty assessment with a civil fine of up to $2,000 per day, appealable to municipal court.

Frequently Asked Questions

What is Hackensack's decibel limit for a loud bang or slam?
Section 112-7B caps impulsive sound, a single peak or burst under one second, at 80 decibels between 7:00 a.m. and 10:00 p.m. The same 80-decibel cap applies overnight as long as it happens fewer than four times an hour; repeat it four or more times in an hour and the code measures it as continuous sound against the lower Tables I and II limits instead.
Where does Hackensack measure noise for a decibel violation?
At or within the real property line of the receiving property listed in Tables I, II or III, per § 112-7A. For an interior complaint the officer measures at least three feet from any wall, floor or ceiling under § 112-6B, with windows and doors in a consistent, comparable position and other household sound sources shut off.
Do Hackensack's decibel limits change based on the time of day?
Yes. Tables I through III set different maximum sound levels depending on the source and receiving property category and the time of day, and the impulsive sound rule in § 112-7B explicitly splits 7:00 a.m.-10:00 p.m. from 10:00 p.m.-7:00 a.m., with a stricter frequency threshold at night before a sound counts as continuous rather than impulsive.
