2015 IECC Update

In July 2015, the Hawaii State Building Code Council unanimously approved the 2015 International Energy Conservation Code (IECC) with amendments.  The code sets energy efficiency requirements for both residential and commercial buildings.

Following Council adoption, the state follows the Administrative Rule path to state adoption and the counties follow the County Council path to county adoption.  The Administrative Rule path involves approval by the Attorney General, review by the Legislative Review Board, approval by the Small Business Regulatory Review Board, and a public hearing scheduled for December 8, 2016.

The county path involves review by the Corporation Councils followed by a minimum of three County Council hearings and approval by the mayors.  The code is then enforced via the plan checking and site inspection process.

Until each county adopts the 2015 IECC, the counties of Hawaii, Maui and Honolulu enforce the 2006 IECC; Kauai, the 2009 IECC.  However, the prevailing codes are a minimum, and designers and builders may follow the 2015 IECC.
