Summary

Full Breakdown

Pennsylvania has no statewide construction-noise statute, and Chester County does not regulate construction hours. Each municipality sets its own limit under its MPC-delegated police power. West Chester Borough Code Chapter 73-3(B)(2) is a typical example: it prohibits operating construction, drilling, demolition or parking-lot-sweeping equipment 9:00 PM to 7:00 AM on weekdays and Saturdays, or at any time on Sundays or legal holidays, where the sound creates unreasonable noise. Contractors should confirm the exact hours for the specific borough or township where the project sits, since surrounding townships adopt different schedules.

Violations & Fines

Enforced by the municipality. In West Chester, a Chapter 73 violation is a summary offense subject to fines under Section 73-5; each day may be a separate offense.
