Industrial and stationary-source noise in Kailua is capped by Hawaii HAR 11-46 maximum dBA limits tied to zoning class, with ROH Chapter 41 Article 6 supplementing local enforcement.
Kailua has limited heavy industry, but HVAC units, generators, commercial refrigeration, and auto repair shops along Kailua Road and Kuulei Road must meet HAR 11-46 maximum permissible sound levels measured at the property line. Limits vary by zoning class: Class A (residential) is tightest, with 55 dBA daytime and 45 dBA nighttime. DOH enforces by complaint investigation and dBA measurement. ROH Chapter 41 Article 6 covers general prohibited noise from commercial operations. Persistent industrial-noise violations can lead to administrative orders requiring abatement.
DOH administrative penalties up to $10,000 per day; ROH §41-6 violations carry civil fines starting at $100.
