Waipahu commercial and industrial noise sources follow ROH Chapter 41 Article 6 and state HAR 11-46 dBA limits, protecting the CDP's dense residential blocks.
Waipahu carries plantation-era industrial roots and active light-industrial activity along Farrington Highway and Kunia Road. ROH Chapter 41 Article 6 (Sections 41-6.1 through 41-6.5) establishes local prohibited-noise standards, and state HAR 11-46 sets maximum permissible dBA by zoning class. Waipahu's predominantly Class A residential neighborhoods are held to the strictest limits at the property line. Former sugar-mill-area redevelopments and small manufacturing operations must meet HAR 11-46 limits measured at the nearest Waipahu home. DOH enforces dBA exceedances; HPD handles plainly-audible violations.
DOH may issue abatement orders and fines for HAR 11-46 violations. HPD can also issue citations for plainly-audible violations of ROH Section 41-6.1 affecting Waipahu homes.
