relative to the state building code.

HB 134 updates New Hampshire's definition of the "state building code" to adopt specific versions of international construction standards. It directly affects builders, architects, and property owners by requiring compliance with the 2021 International Building Code, 2021 International Existing Building Code, 2021 International Plumbing Code, 2021 International Mechanical Code, 2018 International Energy Conservation Code, 2021 International Swimming Pool and Spa Code, 2021 International Residential Code, and the 2023 National Electrical Code. The bill specifies these codes must be reviewed and recommended by the state building code review board and ratified by the legislature. This change ensures all new construction and major renovations statewide follow these updated, nationally recognized standards.
