Full Breakdown

Lewisville Code Chapter 18 applies the plainly-audible standard to industrial and commercial noise sources. Facilities in industrial-zoned districts along Business 121, State Highway 121, and the Railroad Street corridor must ensure noise does not cross into neighboring residential zones at disruptive levels. The citys zoning ordinance provides buffer requirements between industrial and residential uses. HVAC equipment, compressors, loading dock operations, and manufacturing machinery are common complaint sources. TCEQ regulates air emissions and associated noise for permitted industrial facilities under 30 TAC Chapter 111 but does not enforce municipal noise ordinances. Complaints about industrial noise should be directed to Lewisville Code Compliance at (972) 219-3450 for local enforcement or to TCEQ Region 4 (Dallas-Fort Worth) for state-permitted facilities. The DFW area is an EPA ozone nonattainment zone, so some industrial operations face additional emissions monitoring that can affect operational hours.

Violations & Fines

Class C misdemeanor; fine up to 500 dollars per day. Zoning violations subject to separate penalties.
