Industrial and stationary-source noise in Ewa Gentry is capped by Hawaii HAR 11-46 dBA limits tied to zoning class, with ROH Chapter 41 Article 6 supplementing enforcement at commercial and industrial sites.
Although Ewa Gentry is primarily residential, HVAC units, backup generators, refrigeration compressors at Laulani Village, and nearby industrial operations along the Ewa Plain must meet HAR 11-46 maximum permissible sound levels measured at the property line. Class A (residential) limits are 55 dBA daytime and 45 dBA nighttime. DOH investigates complaints with calibrated sound meters and can issue administrative orders requiring abatement. ROH Chapter 41 Article 6 adds local prohibited-noise authority for HPD enforcement of commercial operations disturbing adjacent housing.
DOH administrative penalties up to $10,000 per day; ROH §41-6 violations start at $100 per incident.
