relative to updating the state building code.

HB 1159 updates New Hampshire's definition of the state building code to reference the 2024 editions of key model codes, including the International Building Code and International Plumbing Code, instead of the previous 2021 versions. This change directly affects builders, contractors, architects, and building inspectors who must comply with the updated code standards for new construction and renovations. The bill specifies that the 2024 versions, along with the National Electrical Code 2023, become effective upon legislative ratification and review by the state building code review board. It does not create new requirements but aligns state law with current model code standards.
