Lighting Regulations in Honolulu, Hawaii: Balancing Urban Development, Safety, and Environmental Protection

Introduction

Nestled between mountains and ocean, Honolulu has evolved from a significant port city into a vibrant capital that balances modern development with natural beauty and cultural heritage. The city's lighting regulations reflect this delicate balance, addressing the needs of an urban center while preserving Hawaii's unique environment and cultural identity.

Honolulu's regulations recognize the island's distinctive challenges – protecting native wildlife sensitive to artificial light, preserving dark skies for cultural and astronomical purposes, and creating safe, navigable urban spaces. As a crossroads of Pacific cultures since 1845, the city's approach to lighting embodies respect for both its diverse architectural heritage and natural surroundings.

Quick Reference Guide to Honolulu Lighting Regulations

• Street lighting fixtures must be full-cutoff or semi-cutoff designs (installed after July 1, 2013)
• Commercial and industrial developments must use shielded lighting with full cut-off fixtures
• Shoreline properties require specially shielded lighting to protect marine life and seabirds
• High-efficacy lighting defined as minimum 70 lumens per watt for lamps and 55 lumens per watt for fixtures
• Swimming pools require minimum 0.50 watts per square foot of pool surface area for night use
• Emergency lighting must comply with IBC Chapter 27 and NFPA 70 requirements

Street Lighting Requirements

Fixture Design Standards

All new and replacement municipal street lighting fixtures installed after July 1, 2013, must be either:

• Full-cutoff fixtures: All light is projected below the horizontal plane of the lowest point of the fixture
• Semi-cutoff fixtures: At least 90% of light is projected below the horizontal plane

These fixtures must provide illumination and uniformity equal to or better than the recommendations of the Illuminating Engineering Society of North America.

Energy Efficiency Requirements

Street lighting in Honolulu must meet strict energy efficiency standards:

• All new and replacement municipal street lighting fixtures must equal or exceed the energy efficiency of low-pressure sodium lighting
• Exceptions may be granted by the chief engineer in accordance with Hawaii Revised Statutes Chapter 91

Installation Requirements for New Developments

Developers establishing new subdivisions must:

• Install street lights according to department standard specifications
• Pay for energizing the street lighting system when the first home is occupied
• Maintain the lighting system until roads are dedicated to and accepted by the city
• Submit plans and specifications for approval before installation

Commercial and Outdoor Lighting Regulations

General Requirements

Honolulu's code establishes clear parameters for lighting in commercial areas:

• Full cut-off fixtures required: For any commercial, industrial, or outdoor recreational development
• Light trespass prevention: Outdoor lighting must be shielded to eliminate direct illumination to adjacent residential and other sensitive zoning districts
• Subdued illumination: Lighting must be designed to prevent glare and light spillage onto surrounding properties and rights-of-way

Parking Area Requirements

Special attention is given to parking areas, which often represent significant sources of light pollution:

• Surface parking lots: Lighting must be designed or shielded to prevent direct illumination toward other zoning lots or streets
• Structured parking: Illuminated areas within and on roofs must be shielded to prevent direct illumination outside the structure
• Low-level lighting: Many districts specifically require only low-level or indirect lighting for parking areas

Commercial Establishment Specifics

• Automobile service stations, car washes, and car rental establishments: Must be illuminated so that no unshielded, unreflected, or undiffused light source is visible from any public area or adjacent property

Environmental Protection Measures

Shoreline and Marine Life Protection

Honolulu's coastal position necessitates special lighting considerations:

• Shoreline property lighting: All exterior lighting must be shielded to protect seabirds and marine life
• Directional limitations: Artificial light cannot directly illuminate or project across property boundaries toward the shoreline or ocean waters
• Construction lighting: Shielded lighting requirements apply both during and after construction

Wildlife Considerations

Multiple sections of the code emphasize minimizing impact on native wildlife:

• Seabird protection: Specifications to avoid disorienting native seabirds with artificial light
• Avifauna (bird) protection: Requirements to minimize adverse lighting impacts on native and migratory birds
• Fully shielded fixtures: Recommended throughout to reduce impact on wildlife while meeting safety requirements

District-Specific Requirements

Preservation Districts (P-2)

• Only indirect illumination permitted: Direct illumination of signs prohibited
• No fluorescent or high-intensity lamps: These are specifically prohibited to maintain the serene quality of preserved areas

Chinatown Special District

• Direct and indirect illumination allowed for most sign types, with specific limitations:
• Garden signs cannot be directly illuminated
• Maximum two illuminated signs per ground floor establishment
• Directly illuminated signs must use neon or bulbs affixed to exteriors
• Box fluorescent signs prohibited

Properties Near Cultural Landmarks

Properties fronting King Kamehameha III at Thomas Square or the Honolulu Museum of Art must follow:

• Sign illumination restrictions: No direct illumination, moving parts, luminous paints, or reflective materials
• Subdued lighting: All exterior lighting must be designed to avoid producing glare
• No fluorescent or high-intensity lamps

Building Code Requirements

Efficiency Standards

• High-efficacy lighting definition: Minimum 70 lumens per watt for lamps and 55 lumens per watt for fixtures
• Required in residences: Code section R404.1.2 mandates high-efficacy lighting in residential applications

Emergency Lighting Requirements

• Emergency systems: Must comply with IBC Chapter 27 and NFPA 70 Articles 700 and 701
• Required components: Emergency lighting system and illuminated exit signs
• Public spaces: Hallways, stairs, and other exitways must be adequately lighted at all times

Swimming Pool Illumination

• Minimum illumination: For night use, not less than 0.50 watts per square foot of pool surface area

Habitable Spaces

• Every habitable room must contain at least two electrical convenience outlets or one outlet and one electric light fixture
• Water closet compartments, bathrooms, laundry rooms, furnace rooms, and public hallways must contain at least one electric light fixture
