Honolulu FAQ
Does the 30-foot rule apply to music played inside a parked car?
Yes. ROH § 41-6.1 applies to sound devices operated in motor vehicles on public streets or public property if the sound is audible 30 feet away.
Can a business use outdoor speakers on the sidewalk?
Outdoor amplification audible at 30 feet on public property violates § 41-6.1. Commercial sound vehicles also require a police permit and cannot operate after 9 PM.
Waipahu FAQ
Can Waipahu Town Center host outdoor events?
Yes, but amplified systems must comply with LUO Section 21-4.80 because the center adjoins residential zoning. Operators typically cap volume and end times for Waipahu neighbors.
What about cultural festivals at Hans L'Orange Park?
Permitted public events may get noise variances, but baseline ROH 41-6.1 audibility standards still apply unless the permit expressly authorizes higher levels.
