repealing municipal amendments to technical requirements of the state building code in certain circumstances.

SB 94 prohibits New Hampshire municipalities from creating new local building, energy, or fire code regulations that differ from the state codes after July 1, 2025. It allows existing local amendments in effect as of that date to remain valid but bans any new local modifications. The bill directly affects cities and towns that previously had the authority to adopt supplementary code requirements. All municipalities must now fully comply with the state codes without local changes, though they may continue enforcing pre-July 2025 local amendments.
