New Hampshire building codes

New Hampshire adopts a single statewide New Hampshire State Building Code under RSA 155-A, implemented through the rules of the State Building Code Review Board (Division of Fire Safety). The 2009 editions of the International Building, Residential, Plumbing, Mechanical, and Energy Conservation Codes formed the statewide code from April 1, 2010 until superseded by the 2015 editions in September 2019. Fire safety is handled under the separate State Fire Code. The model-code text below is the edition the state adopted.

Where verbatim source text is shown, it is reproduced from the code as adopted into law by the jurisdiction, sourced from public.resource.org under the government edicts doctrine (see Georgia v. Public.Resource.Org, Inc., 590 U.S. 255 (2020)). This material reflects enacted law and is provided for reference and educational purposes only. It is not legal advice and may not reflect local amendments or the most recently adopted edition. Always verify requirements with the authority having jurisdiction.
