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.

Do I need MMA approval for new outdoor lights?
Typically yes. MMA architectural review applies to exterior lighting changes beyond basic bulb replacement.
