# New Hampshire - Canonical: https://harth.build/resources/building-codes/us-states/new-hampshire/ ## Direct answer and reference scope New Hampshire is presented here as a reference within the the listed code collection collection for New Hampshire. Use the [New Hampshire General Court, RSA 155-A](https://gc.nh.gov/rsa/html/xii/155-a/155-a-mrg.htm) to confirm the code edition currently adopted for the project, and compare the model text with state amendments, local amendments, effective dates and the permit authority's interpretation. The [ICC code library](https://codes.iccsafe.org/codes) is the model-code publication path. This Harth page is a searchable reference transcription, not an official code publication, legal opinion or confirmation that this edition controls a particular address. Record the project jurisdiction, application date, occupancy, construction type and amendment set before relying on a section. Where this page conflicts with an official publication or the authority having jurisdiction, the official source controls. _Authored and prepared by Harth. Review scope: official verification path added; code text and current local applicability have not been independently reviewed._ 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Residential, Plumbing, Mechanical, and Energy Conservation Codes formed the statewide code from April 1, 2010 until superseded by the 2015 editions in September 2019.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. --- - Continue in Harth (open this topic in the Harth agent): https://app.harth.build/agent?context=%2Fresources%2Fbuilding-codes%2Fus-states%2Fnew-hampshire%2F - View this page in a browser: https://harth.build/resources/building-codes/us-states/new-hampshire/ - All resources for agents: https://harth.build/llms.txt
