Montgomery County, PA Noise Ordinances: Quiet Hours (2026)

Pennsylvania is a strict-construction state for county police power. Counties of the second class A (which includes Montgomery County) cannot enact a general noise ordinance applicable inside the county's 62 townships and boroughs; the MPC (Act 247, 53 P.S. §10101 et seq.) reserves zoning, nuisance, and noise regulation to the local governing body. As a result, residents must consult their specific municipality's code on eCode360 or the township website. Norristown Borough Code Chapter 215 (Noise) prohibits loud, unnecessary or unusual noise that annoys or disturbs others, and Chapter 215 specifically bars construction-related noise from 7:30 p.m. to 7:00 a.m. Monday through Friday and from 8:00 p.m. to 9:00 a.m. on Saturday and Sunday; private parties may not generate noise audible to neighbors at 25 feet or more. Lower Merion Township (Chapter 109, Noise) applies sound-level limits at the property line with a daytime period of 8:00 a.m. to 8:00 p.m. and a nighttime period of 8:00 p.m. to 8:00 a.m., with maximum decibel limits varying by zoning district. Abington Township and most other Montgomery County municipalities have similar nuisance and time-of-day construction restrictions. As a statewide backstop, 18 Pa.C.S. §5503 (Disorderly Conduct) makes it a summary offense to make unreasonable noise with intent to cause public inconvenience or recklessly creating that risk; this is enforced by municipal police, the PA State Police, and constables. There is no Montgomery County Sheriff's Office that handles noise complaints (the Sheriff's role in PA is limited to court security and warrants); call your local municipal police department's non-emergency line or 911 for an active disturbance.
