Connecticut pauses required building code updates until 2030 models while its delayed 2026 code awaits approval
A law in force since October 1, 2026 lengthens the state's code update cycle, while the codes built on the 2024 model codes still lack legislative approval and an effective date.
Builders designing Connecticut projects still do not know when the next building and fire codes will apply, and a new law means that once they do, the state will not be required to update them again for years. Conn. Pub. Act No. 26-58 (2026), An Act Concerning Revisions to the State Building Code, State Fire Prevention Code and Fire Safety Code (Substitute House Bill 5401), approved May 26, 2026 and effective October 1, 2026, amends Conn. Gen. Stat. §§ 29-252(a), 29-291a(a) and 29-292(a)(1) so that no revisions are required after the first publication of the 2024 model codes and before the first publication of the 2030 model codes.
