Summary
Noted: Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP web sites.
New Hampshire adopted a mandatory statewide building code in 2002 based on the 2000 IECC. S.B. 81, enacted in July 2007, upgraded the New Hampshire Energy Code to the 2006 IECC. In December 2009, the New Hampshire Energy Code was again updated. The New Hampshire State Building Code Review Board adopted the IECC 2009 as the new statewide code effective April 1, 2010. The local building official enforces the energy requirements.
Local governments may adopt different requirements only if those requirements are more stringent than the state code. The New Hampshire Building Code Review Board has rulemaking authority to change the standards within the code.
As of September 15, 2022, New Hampshire has adopted the 2018 IECC building codes across residential and commercial buildings.
