Honolulu FAQ
Where are the decibel numbers for factories?
Zoning-based maximum permissible sound levels for stationary sources appear in state rule HAR 11-46, not directly in the Revised Ordinances of Honolulu.
Can the City cite an industrial facility?
Yes. Honolulu police and inspectors can cite under ROH Chapter 41 Article 6 in addition to state enforcement under HAR 11-46.
Urban Honolulu FAQ
How are dBA limits set near Kakaako condos?
HAR 11-46 applies maximum permissible sound levels based on the receiving property's zoning class, which in Kakaako typically mixes apartment and commercial standards.
Can residents sue an industrial source?
Private remedies exist separately under nuisance law; regulatory enforcement through HAR 11-46 and ROH Chapter 41 is the primary public channel.
