Summary
In the City of Waterloo, Iowa, loading, unloading or otherwise handling boxes, crates, containers, building materials or garbage cans is a prohibited noise act under the Noise Control Ordinance whenever the racket crosses a residential property line above the city's Table II decibel caps. The ceiling tightens sharply overnight, and the Waterloo Police Department enforces it as a municipal infraction.

Full Breakdown
City Code section 4-5-4, part of chapter 5's Noise Control Ordinance, prohibits "loading, unloading, opening, closing or other handling of boxes, crates, containers, building materials, garbage cans or similar objects" that creates a noise level exceeding Table II across a residential real property boundary or inside a city council-designated noise sensitive zone. Table II caps daytime noise (7:00 A.M. to 11:00 P.M.) at 80 dBA in residential and commercial areas and 82 dBA in industrial areas, dropping overnight (11:00 P.M. to 7:00 A.M.) to 55 dBA residential, 60 dBA commercial and 75 dBA industrial.
Readings are taken at the nearest lot line, never closer than 25 feet from the source, so a delivery crew banging around a loading dock at 2:00 A.M. near homes is measured against the 55 dBA overnight floor rather than the looser daytime number. The rule applies to any handling of the listed objects, not just truck-based deliveries, and covers commercial haulers, warehouse staff and retail employees alike. Because the standard is objective decibel measurement rather than a blanket curfew, a business can legally receive deliveries at any hour as long as the resulting noise at the nearest residential boundary stays under the applicable Table II number.
Section 4-5-5 lets the mayor grant a special variance where meeting the limit would be an unreasonable hardship, weighed against the impact on nearby residents and public safety, with any variance carrying set conditions and a time limit.
Violations & Fines
Violating section 4-5-4 is a municipal infraction under section 4-5-7, fined as provided in section 1-3-2C, with each day the noise continues counted as a separate offense. Section 4-5-8 lets a police officer instead issue an abatement order before citing a business, and section 4-5-9 allows the city or an affected resident to seek a court injunction against a chronic offender.
