2018 IECC Update
In July 2018 the Hawaii State Building Code Council (SBCC) unanimously approved the 2018 International Energy Conservation Code (IECC) with amendments. The code sets energy efficiency requirements for both residential and commercial buildings.
The county path involves review by the Corporation Councils followed by County Council hearings, amendments, adoption, and approval by the mayors. The code is then enforced via the plan checking and site inspection process.
