Kailua FAQ
Can I demand a neighbor dim a bright porch light in Coconut Grove?
You can pursue a private nuisance complaint if light substantially interferes with your reasonable use of your home.
Does this cover LED upgrades?
Yes. Any new or replacement fixture in covered developments must still meet the shielding requirements.
Waipahu FAQ
Is there a foot-candle limit at Waipahu property lines?
No. Honolulu does not set a numeric limit. Enforcement requires proving noncompliant commercial or recreational fixtures under LUO 21-4.100.
What if a Waipahu business floodlight shines into my bedroom?
File a DPP complaint citing LUO 21-4.100 if the fixture is commercial, industrial, or recreational. Persistent issues may also support an ROH Chapter 41 nuisance claim.
Are residential porch lights regulated?
LUO 21-4.100 targets commercial, industrial, and recreational development. Single-family residential fixtures fall under nuisance law rather than the zoning shielding rule.
