Construction hours in East Honolulu, HI — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Under HAR 11-46-7(j), a community noise permit may not authorize construction noise exceeding the limits before 7:00 a.m. or after 6:00 p.m. Monday through Friday, before 9:00 a.m. or after 6:00 p.m. on Saturday, or at all on Sundays and holidays.
Construction noise in East Honolulu is regulated by the state Department of Health under HAR Chapter 11-46. Because construction equipment routinely exceeds the residential 55 dBA daytime limit, contractors generally must obtain a community noise permit, and section 11-46-7(j) sets specific permit restrictions for construction activities: no permit may allow construction noise above the maximum permissible sound levels before 7:00 a.m. or after 6:00 p.m. the same day Monday through Friday; before 9:00 a.m. or after 6:00 p.m. on Saturday; or on Sundays and holidays. Permit fees are $25 per year for single-family-dwelling work and $50 per year for all other construction (11-46-7(i)). Work outside these hours (including off-hour roadwork between 6:00 p.m. and 7:00 a.m.) requires a noise variance under 11-46-8, which carries a $100-per-year fee plus public-notice costs. Section 11-46-6 also requires that on-site vehicles and construction equipment be operated with a functioning, unmodified muffler.
Violating the permit hour restrictions or operating without a required permit/variance is subject to HAR 11-46-16 penalties of up to $10,000 per day, with each day a separate offense.
