Code Adoption and Change Process

Code Change Process

Legislative and Regulatory Process:

Ohio Building Code: Revisions and updates are promulgated by the Ohio Board of Building Standards (BBS), the primary state agency authorized to protect the public’s safety and welfare in building design and construction. Any BBS recommendations are then submitted by Ohio legislature’s Joint Committee on Agency Rule Review (JCARR), and finally go through the state’s administrative review procedures before any updates become effective.

Residential Code of Ohio: An energy subcommittee of the Residential Codes Advisory Council (RCAC) provides recommendations on proposed updates to the residential code, which then must be approved by a vote of the RCAC. Those recommendations then follow the same process as Ohio Building Standards updates.

Code Change Cycle

No set schedule

Next Code Update

The Ohio Board of Building Standards (BBS) and Residential Code Advisory Council (RCAC) are currently discussing the 2012 and 2015 IECC.
