Ohio Building and Residential Codes

Ohio’s commercial and residential building codes are based on the International Code Council’s International Building (2021 IBC) and Residential (2018 IRC) codes. The Board of Building Standards sets the building code for Ohio and provides training and certification for local building authorities across Ohio.  The Board of Building Appeals (BBA) hears requests for variance from the Ohio Building Code.

The 2024 Ohio Building Code is based on the 2021 International Building Code and goes into effect March 1, 2024.  The 2019 Residential Code of Ohio is based on the 2018 International Residential Code with Ohio amendments and went into effect July 1, 2019.
