New Hampshire State Building Code and Roofing Legislation

The State of New Hampshire mandates compliance with the New Hampshire State Building Code for the construction, alteration, and repair of buildings. As of the most recent updates, the state has adopted the 2021 editions of the International Code Council (ICC) model codes as the base standards. Specifically, residential roofing projects are governed by the 2021 International Residential Code (IRC), while commercial roofing projects fall under the 2021 International Building Code (IBC). These model codes are adopted by reference under New Hampshire Revised Statutes Annotated (RSA) Chapter 155-A, and they include specific New Hampshire amendments that must be followed.

The primary agency responsible for these standards is the New Hampshire State Building Code Review Board (BCRB). The BCRB is tasked with reviewing model codes, recommending legislation to adopt or amend them, and ensuring consistency in the application of building regulations across the state. While the state sets these minimum standards, enforcement is typically handled at the local municipal level by building officials. In municipalities that do not have a local building official or enforcement mechanism, the State Fire Marshal's Office holds authority for enforcement.
