Middlesex County has no county-wide noise ordinance for residential quiet hours. New Jersey is a strict home-rule state under N.J.S.A. 40:48-1, so each of the county's 25 municipalities sets its own rules. The state baseline is N.J.A.C. 7:29 (NJDEP Noise Control regulations), enforced by certified municipal noise officers. New Brunswick regulates noise under Municipal Code Chapter 8.28 (Noise Control), and Edison Township enforces noise through its police department. Most Middlesex municipalities adopt the NJDEP Model Noise Control Ordinance: 65 dB(A) day / 50 dB(A) night at residential property lines, with 'night' running 10 p.m.-7 a.m. weekdays and 11 p.m.-9 a.m. weekends.
