Honolulu adopts updated International Energy Conservation Code provisions and city sustainability ordinances tied to its Climate Action Plan. New construction and major remodels must meet insulation, cool-roof, and EV-ready standards alongside Hawaii's clean-energy mandates.
Under HRS Chapter 107 the State Building Code Council adopts the International Energy Conservation Code, which Honolulu administers through DPP plan check. Local amendments emphasize tropical climate concerns: solar water heating mandates from Act 204 (2008), cool-roof requirements, and ventilation standards suited to year-round trade winds. The city's 2020 Climate Action Plan and Bill 25 (2022) added EV-ready parking provisions for new multifamily and commercial buildings. Hawaii's statewide goal of 100 percent renewable electricity by 2045 reinforces these rules and Honolulu's net-zero municipal targets.
DPP can deny certificates of occupancy to projects that fail energy-code inspection. Solar-water-heater violations under Act 204 can carry fines, and missing EV infrastructure may force costly retrofits before a final permit signoff.
