Barking dog rules in Wilmington, DE — also called nuisance dog, dog noise, or excessive barking ordinances — define when a barking dog becomes a code violation and how complaints are handled.
Wilmington's noise code prohibits animal noises that create a noise disturbance. Persistent barking in excess of ambient levels or that plainly disturbs neighbors violates city code.
Under Wilmington City Code Ch. 11, Art. III, any sound—including animal noise—that exceeds the residential decibel limits (65 dB daytime, 55 dB nighttime) or that exceeds ambient noise by 5 dB(A) constitutes a noise disturbance. Animal owners can be cited if their pet's barking disturbs neighbors. The 2024 amendment further prohibits noise targeting a specific residence, which can apply to persistent barking.
Owners may be issued a noise disturbance citation. Repeat violations result in escalating fines. Animal control may also become involved under Ch. 3.
