This bill establishes a prohibition on local legislative bodies from enacting any new regulations that differ from the state building code, state energy code, or state fire code. Specifically, it amends RSA 674:51, I to state that local bodies "shall not enact, adopt, or implement any new ordinance, rule, or regulation that amends, overrides, deviates from, or differs from" the aforementioned state codes. Furthermore, it stipulates that all municipalities must fully comply with these state codes without any local modifications. Existing local amendments that were in effect as of July 1, 2025, will remain valid and enforceable, provided they were adopted according to the established procedures.

Additionally, the bill introduces a new section, RSA 155-A:2-a, which explicitly prohibits municipalities from enacting new local amendments to the state codes after July 1, 2025. It also amends RSA 47:22 to reinforce that local bodies cannot pass or adopt new ordinances that contradict the state codes. The effective date for these changes is set for July 1, 2025. Overall, the bill aims to standardize building regulations across municipalities by limiting local authority to amend state codes.
