Macon County, IL Noise Ordinances: Construction Hours (2026)

m. Outside that window, ordinary construction noise loses its exemption and is measured against the same decibel and distance standards that apply to any other noise source on residential land. Even within the exempt hours, the exemption is not absolute: if, in the opinion of the Macon County Planning and Zoning Department, the equipment or activities used on a construction site exceed the allowable decibel levels elsewhere in the chapter, the department may require the contractor to implement noise-mitigation methods at the site. 06. The construction exemption sits in the same section as other Chapter 94 carve-outs, including emergency utility repairs, work performed by a public body such as road and bridge construction, and properly maintained powered maintenance equipment. 08, the chapter's general enforcement provision.
