Construction hours in Honolulu County, HI — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Construction noise across Oahu is controlled by state rule HAR 11-46, not a separate Honolulu ordinance, with permits required outside allowed daytime hours.
Honolulu County does not publish its own construction-hours ordinance. Instead, the State of Hawaii Department of Health regulates construction noise across the island under Hawaii Administrative Rules Title 11, Chapter 46. Typical allowed construction hours are weekdays 7:00 a.m. to 6:00 p.m. and Saturdays 9:00 a.m. to 6:00 p.m., with work outside those hours requiring a community noise permit. ROH Chapter 41, Article 6 supplements state rule with local prohibited-noise provisions.
Unpermitted construction outside authorized hours can draw state Department of Health enforcement, stop-work coordination with Honolulu inspectors, and civil penalties.
