Quiet hours in Waipahu, HI — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Waipahu residents in dense plantation-era neighborhoods must follow ROH Section 41-6.1, which prohibits sound devices audible at 30 feet or more.
ROH Section 41-6.1 makes it unlawful anywhere in Waipahu to operate a sound-reproducing device in a manner plainly audible at 30 feet or more. In Waipahu's historic plantation-town grid, with compact lots and multigenerational Filipino family homes in neighborhoods like Waipahu Depot Street and Waikele-side Waipahu, sound travels quickly across shared fences. State HAR 11-46 Class A residential limits (55 dBA day, 45 dBA night) apply alongside the city prohibited-noise rule, with HPD responding to complaints from the CDP's densely packed leeward blocks.
Fines apply under ROH Chapter 41, with repeat offenses escalating. HPD issues citations to responsible parties after responding to Waipahu neighbor complaints.
