Naperville sets specific decibel thresholds for industrial and commercial zones under Title 6, Chapter 14. Light industrial zones may not exceed 70 dBA and industrial zones may not exceed 80 dBA measured at the property line.
Naperville Municipal Code Title 6, Chapter 14 establishes noise performance standards by zoning district. Light industrial zones cannot exceed 70 dBA and industrial zones cannot exceed 80 dBA, measured at the property line using ANSI S1.4-1983 compliant equipment. Commercial zones have intermediate limits between residential and industrial thresholds. Noise standards apply at all times but stricter limits apply during quiet hours from 7 PM to 7 AM. Industrial operations near residential boundaries must meet the more restrictive residential zone limits at those boundaries. Continuous monitoring may be required for operations with ongoing noise concerns.
Exceeding decibel limits is a zoning violation with fines under the general penalty schedule. Persistent industrial noise violations may trigger nuisance abatement proceedings or conditional use permit review.
