Violations & Fines
Running loud construction equipment between 11:00 p.m. and 6:00 a.m. in a majority-residential block is a direct violation of Sec. 8-65, and a daytime or evening reading above the 80 dB(A) or 75 dB(A) caps in Sec. 8-93(d) is a separate, independently citable violation of the noise pollution article. Both are enforced through municipal court under Sec. 1-5, and Sec. 8-94's exceptions, covering emergency responses and government-sponsored public events, do not cover ordinary private construction work.
