East Honolulu FAQ
Can I measure light trespass at my Hawaii Kai property line?
Honolulu does not set a foot-candle limit. Enforcement requires proving noncompliant fixtures under LUO 21-4.100, not a numerical illuminance threshold.
What if my neighbor's floodlight shines into my Aina Haina window?
You can file a DPP complaint if the fixture is noncompliant commercial or recreational lighting, or pursue a public nuisance claim under ROH Chapter 41.
Are single-family home floodlights regulated?
LUO 21-4.100 targets commercial and recreational development. Single-family residential fixtures fall under nuisance law rather than the zoning shielding rule.
Honolulu FAQ
Can I complain about a neighbor's floodlight?
Yes. If the source is a commercial, industrial, or recreational development, LUO 21-4.100 applies. Residential cases may proceed as public nuisance under ROH Chapter 41.
Is there a property-line brightness limit?
No specific foot-candle cap appears in the ROH. Compliance is measured by whether fixtures are full cut-off and properly shielded toward protected districts.
