Has NH adopted a snow load standard that is different than required in the International Building Code?
No. Due to the lack of snow load data in the IBC and IRC for most NH towns, the Board voted to recommend the Cold Regions Research and Engineering Laboratory ERDC/CRREL TR-02-6 Ground Snow Loads for New Hampshire, US Army Corps of Engineers, as published in February 2002, be utilized as a standard. The report provides a compilation of case studies performed as required by, and in accordance with the IBC, for every town in NH. Acceptance of an alternative method of snow load determination is subject to the approval of the local jurisdiction.
