Code Adoption and Change Process

Code Change Process

Regulatory: The New Hampshire Building Code Review Board has the authority to change the standards within the code. The procedure consists of public hearings held by the board followed by the public adoption or rejection of proposed amendments. The NH State Legislature must ratify any amendments adopted by the board within two years of their effective date; otherwise, the code reverts back to the previous version.

Code Change Cycle

No set schedule

Next Code Update

In August 2015, the New Hampshire State Building Code Review Board (BCRB) held a public hearing on possible revisions to the 2015 IECC. However, in early 2016, the New Hampshire House voted down HB 1282, which would have adopted a (significantly weakened) version of the 2015 IECC. In the meantime, jurisdictions can adopt updated energy codes on their own.
