ROH Chapter 41 Article 6 supplements state HAR 11-46 decibel limits for any industrial or stationary noise sources impacting East Honolulu residential neighborhoods.
East Honolulu is overwhelmingly residential, but stationary noise sources like large generators, commercial HVAC rooftops at shopping centers, and limited light-industrial activity can affect neighbors. ROH Chapter 41 Article 6 (Sections 41-6.1 through 41-6.5) provides local prohibited-noise rules, while state HAR 11-46 sets maximum permissible dBA levels by zoning class, with Class A residential areas (where Hawaii Kai, Aina Haina, and Kuliouou fall) held to the strictest standards. The Hawaii DOH enforces dBA limits; HPD handles plainly-audible prohibited noise.
DOH may issue abatement orders and administrative penalties for HAR 11-46 dBA exceedances. Concurrent HPD citations may apply under ROH Section 41-6.1 for plainly-audible nuisances.
