Jacksonville Ordinance Code Chapter 368 sets decibel limits by zoning district. Industrial-zoned property is generally capped around 75 dBA at the receiving residential property line, 24 hours.
Duval's consolidated zoning code pairs with Chapter 368 to apply stricter nighttime limits (often 55-60 dBA) when industrial noise crosses into residential zones. The Port of Jacksonville, rail yards, and Westside industrial corridor are common complaint sources; the Environmental Quality Division of Regulatory Compliance investigates.
Notice of violation, then civil fines up to $500/day and abatement orders.
