Urban Honolulu's Outdoor Lighting: The Rules That Matter

Every city handles outdoor lighting a little differently. In Urban Honolulu, Hawaii, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Dark Sky Rules

Honolulu's LUO 21-4.100 requires full cut-off shielded outdoor lighting for commercial, industrial, and outdoor-recreational development so that direct illumination does not spill into residential or resort districts, complementing the state night sky strategy.

Key details: Code section: LUO 21-4.100. Fixture type: Full cut-off shielded. Scope: Commercial, industrial, rec. Rooftop areas: Shielded beyond edge. State policy: HRS 201-8.5.

Noncompliant fixtures can lead to LUO citations, permit revocation, and required retrofits under Chapter 21.

Light Trespass

Honolulu addresses light trespass through LUO 21-4.100 shielding and full cut-off fixture requirements rather than a foot-candle property-line standard, with ROH Chapter 41 Public Nuisance available as backup enforcement in residential cases.

Key details: Primary tool: LUO 21-4.100 shielding. Foot-candle limits: None specified. Backup: ROH Ch. 41 nuisance. Districts protected: Residential, resort, country. Rooftop rule: Beyond-edge shielding.

Direct light trespass into protected districts can be cited under LUO 21-4.100 and, in severe residential cases, pursued as a public nuisance under ROH Chapter 41.

The Bottom Line

Urban Honolulu'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 Urban Honolulu is broadly strict or permissive.

Keep in mind that Urban Honolulu can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
