Wilmington's Noise Ordinances: The Rules That Matter

Every city handles noise ordinances a little differently. In Wilmington, Delaware, there are 3 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Quiet Hours

Wilmington prohibits noise exceeding 65 dB(A) in residential areas from 7 AM–11 PM and 55 dB(A) from 11 PM–7 AM. Noise that targets a specific residence is separately prohibited.

Key details: Daytime limit (residential): 65 dB(A), 7 AM–11 PM. Nighttime limit (residential): 55 dB(A), 11 PM–7 AM. Code: City Code Ch. 11, Art. III. Topic: Quiet Hours.

Violations of Chapter 11 are subject to civil penalties. Police or code enforcement may issue orders to cease. Fines increase for repeat violations.

Construction Hours

Construction and power equipment noise in Wilmington must comply with the city's decibel limits. Work creating excessive noise outside normal daytime hours requires a permit exemption.

Barking Dogs

The Bottom Line
