relative to the state building code.

HB 1059 updates the New Hampshire state building code by officially adopting the 2021 editions of seven major international codes, such as those for plumbing and energy conservation, along with the 2020 National Electrical Code. This change directly affects construction professionals, building owners, and inspectors who must now follow these new standards for new and existing structures. The bill also establishes that any future updates to these codes will only become part of the state law if they are reviewed by the state board and approved by the legislature before taking effect. These updated rules will officially go into force on July 1, 2024.
