Tazewell County, IL Noise Ordinances: Decibel Limits (2026)

' This sits within the small wind energy systems subchapter, which requires a site plan submitted to the Community Development Administrator demonstrating compliance with setbacks (110% of system height from adjacent property lines, 150% from any inhabited structure or right-of-way), Uniform Statewide Building Code and National Electric Code compliance, and FAA notification where applicable. Sec. 23 confines small wind energy systems to parcels of at least one acre used as an accessory to a primary structure, bars them from vacant parcels, allows them in all zoning districts except R-1 and R-2, and caps a parcel at one system.

This 60-decibel property-line standard is the only fixed numeric decibel ceiling written directly into Tazewell County's code; the county's larger commercial wind energy facilities instead defer to Illinois Pollution Control Board noise rules (Sec. 06(G)) rather than stating their own number, and the county's mass-gathering amplifier limit under Sec. 04(C)(9) is a separate 70-decibel standard that only applies to large permitted events, not to fixed installations like turbines.
