Building and Fire Code Adoption Process


State Building, Fire Safety and Fire Prevention Codes Update

The next state building, fire safety and fire prevention codes are scheduled to go into effect on October 1st, 2022, subject to securing legislative approval on September 27th, 2022.

More information on the September 27th Legislative Regulation Review Committee meeting can be found here:

The new state codes will be known as the:

  • 2022 Connecticut State Building Code
  • 2022 Connecticut State Fire Safety Code
  • 2022 Connecticut State Fire Prevention Code

The final versions of the codes will be published under documents on this web page

A list of the model codes to be adopted are also on that page, and those model codes are available to view for free on the International Code Council and National Fire Protection Association web sites:

The development of Connecticut specific versions of the International Building Code (IBC), International Residential Code (IRC), International Fire Safety Code (IFC), NFPA 1 and NFPA 101, is underway.

The new codes will apply to projects for which a permit is applied for after the effective date. If you have a project that will be significantly impacted by this change in codes, you may apply for a code modification from the Office of the State Building Inspector and the Office of the State Fire Marshal (separate applications) to allow the project to continue under the 2018 state codes. This process, colloquially known as a grace period, will be available for approximately three months from the effective date. See the code modification web page for more information

The department is also providing free online training on the significant changes in the new codes and other related topics through its learning management system. More information and user instructions are available on the LMS web page.

In the meantime, if you have any questions, please e-mail the team at and a team member will get back to you.
