Urban Honolulu industrial noise in Mapunapuna, Sand Island, and Iwilei is capped by HAR 11-46 dBA limits with local backup from ROH Chapter 41 Article 6.
Urban Honolulu has significant industrial zoning in Iwilei, Sand Island, and Mapunapuna where stationary sources can affect adjacent residential and mixed-use areas. Revised Ordinances of Honolulu Chapter 41, Article 6 supplies the local prohibited-noise framework through sections 41-6.1 through 41-6.5. Primary decibel limits for stationary industrial sources are set by the State Department of Health under HAR 11-46, which assigns maximum permissible noise levels by zoning class.
The Department of Health can issue notices of violation with civil penalties; Honolulu police and inspectors can cite under Chapter 41 as a supplementary tool.
