Stationary-source industrial noise on Oahu is capped primarily by state rule HAR 11-46 with local backup from Honolulu's noise control article.
Revised Ordinances of Honolulu Chapter 41, Article 6 (sections 41-6.1 through 41-6.5) supplies Honolulu's general prohibited-noise rules. Primary dBA 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 across the island. ROH Article 6 supplements state rule with local prohibited-noise provisions that police and inspectors can cite directly.
DOH can issue notices of violation and civil penalties; the City can cite under Chapter 41 when noise is plainly audible beyond the statutory threshold.
