How Pearl City Handles Outdoor Lighting: A Practical Guide

Pearl City maintains 106 local ordinances across all categories, and 2 of those deal specifically with outdoor lighting. Here is a breakdown of what the city actually requires, what is prohibited, and where Pearl City falls on the strict-to-permissive spectrum compared to other cities.

Dark Sky Rules

Pearl City commercial, industrial, and recreational development must use full cut-off shielded fixtures under ROH 21-4.100, protecting residential neighborhoods and Pearl Harbor security lighting corridors.

Key details: Code section: ROH 21-4.100. Fixture type: Full cut-off shielded. Applies to: Commercial/industrial. State companion: HRS 201-8.5. Rooftop rule: Shield beyond rooftop.

Noncompliant fixtures trigger DPP notices of violation, daily zoning fines, and required retrofit to full cut-off shielded lamps within specified cure periods.

Light Trespass

Pearl City light trespass is controlled through shielding and cutoff requirements in ROH 21-4.100, preventing direct illumination onto residential Pearl City Highlands, Waimalu, and Manana neighborhoods.

Key details: Code section: ROH 21-4.100. Method: Full cut-off shielding. Foot-candle limit: None set. Nuisance backstop: ROH Ch. 41. Protected zones: Residential, country.

Light trespass violations trigger DPP notices of violation under ROH 21 and, in persistent cases, Public Nuisance enforcement under ROH Chapter 41 with fines and abatement orders.

The Bottom Line

Pearl City's outdoor lighting rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Pearl City is broadly strict or permissive.
