Aiea Zoning & Land Use Guide
Key Zoning Facts
Aiea Zoning Overview
Aiea is a census-designated place in central Oahu situated above the north shore of Pearl Harbor. The community serves as a commercial hub anchored by Pearlridge Center, one of the largest shopping malls in Hawaii. As part of the City and County of Honolulu, all zoning and permitting is handled by the Honolulu Department of Planning and Permitting. Aiea's hillside location provides many homes with panoramic views of Pearl Harbor and the Waianae Range.
Residential development in Aiea ranges from older single-family neighborhoods on the hillside to newer condominium and apartment complexes near the commercial corridor. The community's central location at the junction of H-1 and H-99 (Moanalua Freeway) makes it a transportation crossroads, and the planned Pearlridge station on the Honolulu Skyline rail system is expected to bring transit-oriented development opportunities to the area.
Key Zoning Districts
Aiea features R-5 residential zones on the hillside, A-1 and A-2 apartment districts near Pearlridge Center, B-2 commercial zoning serving the Pearlridge and Newtown areas, and I-1 industrial zones along the lower harbor area. Transit-oriented development overlay zones are anticipated near the future rail station.
ADU Regulations
Aiea follows the Honolulu ohana unit ordinance. ADUs up to 800 square feet are permitted on qualifying residential lots. The hillside terrain of many Aiea properties may affect site feasibility and construction costs for accessory dwelling units, as grading and foundation requirements can increase on sloped lots.
Development Process
Building permits are issued by the Honolulu Department of Planning and Permitting. Hillside properties may be subject to grading permit requirements and geotechnical review. The Primary Urban Center Development Plan provides policy guidance for Aiea, and future transit-oriented development near the Pearlridge rail station is expected to encourage densification in the area.
