  • 2024 Ohio Mechanical Code

    2024 Ohio Mechanical Code

    $124.99

    The 2024 Ohio Mechanical Code, effective March 1, 2024, adopts the 2021 International Mechanical Code (IMC) along with Ohio‑specific amendments. A key objective of this update is simplification and clarity: the code has about 85% fewer words than the prior version, with over 2,500 regulatory restrictions removed. Instead of duplicating unchanged model code text in Ohio’s administrative rules, only amended portions are explicitly included, making it easier to discern what is uniquely Ohio’s requirement versus the baseline from the IMC. The OMC applies to commercial systems—such as heating, ventilation, air conditioning, refrigeration, air pollution control, incineration, and related mechanical installations—not covered under the Residential Code of Ohio.
