Monroe Township (Middlesex County), NJ Public Conduct: Loud Party Ordinance (2026)

The Monroe Township Code (Middlesex County) handles a noisy party through the Noise Control Ordinance for Stationary Sources in Chapter 69. Section 69-7A is the catch-all: no person can cause, suffer, allow or permit to be made verbally or mechanically any unnecessary noise. The wording reaches the person who lets the noise happen as well as the person making it, because the verbs include suffer, allow and permit, and it covers voices as well as speakers. The only exemption in that subsection is for noncommercial public speaking and public assembly activities conducted on a public space or public right-of-way.

Section 69-7B adds specific acts. Subsection (1)(b) bars operating a radio, television, phonograph or similar device in a way that creates unnecessary noise for any person other than the operator, and (1)(c) bars a sound level across a real property line, or through partitions common to two or more persons within a building, above an applicable Table 1 limit. Subsection (2) bars loudspeakers and public address systems between 10:00 p.m. and 8:00 a.m. the following day when they create unnecessary noise across a residential real property line.

Table I in § 69-6 prints 50 as the night limit at a residential receiving property. Section 69-3 defines noise as any sound of such level and duration as to be or tend to be injurious to human health or welfare or that would unreasonably interfere with the enjoyment of life or property. The Health Department administers the article, and its Noise Control Officer issues notices of violation or abatement orders. Section 69-9D adds that nothing in the article impairs any common law or statutory cause of action or legal remedy of a person for injury or damage.
