Quiet hours in Honolulu County, HI — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Oahu's island-wide prohibited-noise rule bars disturbing sounds at all hours, with the 30-foot audibility test commonly applied to amplified devices.
Because the City and County of Honolulu is consolidated and covers the entire island of Oahu, Revised Ordinances of Honolulu Chapter 41, Article 6 applies uniformly across urban, suburban, and rural communities. Section 41-6.1 targets prohibited noise, including sound-reproducing devices that are plainly audible from 30 or more feet away. Community-wide decibel limits tied to zoning are administered through Hawaii Administrative Rules Chapter 11-46 by the State Department of Health, which works alongside the county prohibition.
Violations are typically enforced by the Honolulu Police Department through citation, abatement, and, for continuing problems, referral to state noise regulators.
