Ohio Mechanical Code – 2017
Ohio Mechanical Code – 2017
Book Overview
The 2017 Ohio Mechanical Code (OMC) is a state-specific adaptation of the 2015 International Mechanical Code (IMC), developed by the Ohio Board of Building Standards (BBS) to regulate the installation, maintenance, and inspection of mechanical systems in buildings throughout Ohio. Effective from November 1, 2017, the OMC ensures that mechanical systems—such as heating, ventilation, air conditioning (HVAC), and refrigeration—are installed and maintained in a manner that protects public health, safety, and welfare.
Key Aspects:
Scope and Application
- Applies to the construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal, and demolition of mechanical systems within Ohio.
- Regulates systems such as heating, ventilation, air conditioning, and refrigeration.
- Excludes certain structures such as live/work units located in townhouses complying with specific requirements.
General Regulations
- Materials used shall be installed in strict accordance with the standards under which the materials are accepted and approved.
- All mechanical products and materials shall be listed by a third-party certification agency as complying with the referenced standards.
- Mechanical systems shall be designed and installed to prevent rodents from entering structures.
- Piping shall be protected against external corrosion by a protective sheathing or wrapping or other means that will withstand any reaction from the lime and acid of concrete, cinder, or other corrosive material.
Specific Systems and Components
Provides detailed requirements for various mechanical systems and components, including:
- Heating and Cooling Equipment: Specifications for the installation and maintenance of furnaces, boilers, air conditioners, and heat pumps.
- Ventilation Systems: Requirements for natural and mechanical ventilation to ensure adequate indoor air quality.
- Duct Systems: Standards for the design and installation of ductwork, including sizing, materials, and insulation.
- Refrigeration Systems: Guidelines for the safe installation and operation of refrigeration equipment.
- Exhaust Systems: Requirements for the safe removal of air contaminants from buildings.
Energy Efficiency and Sustainability
- Aligns with the state’s energy conservation goals by incorporating provisions that promote energy-efficient design and operation of mechanical systems.
- This includes requirements for system performance, controls, and integration with other building systems.
Highlights:
- Update & Adoption
- Alignment with National Standards
- Streamlining & Clarity
- Key Technical Areas
Key Features & Benefits
The 2017 Ohio Mechanical Code provides a statewide standard for the design, installation, maintenance, alteration, and inspection of mechanical systems in non-residential buildings. Based on the 2015 International Mechanical Code (IMC) and amended for Ohio-specific needs, it ensures mechanical system safety, energy efficiency, and occupant health. Key Areas of Coverage:
- General Mechanical System Requirements
- Ventilation Systems
- Duct Systems
- Combustion Air & Venting
- Heating and Cooling Equipment
- Appliance Installation
- Fuel Gas Piping
- Refrigeration Systems
- Mechanical System Controls
- Special Requirements
The 2017 Ohio Mechanical Code (OMC) is designed for direct application by a wide range of construction and mechanical professionals, including HVAC contractors, engineers, inspectors, architects, and code officials. It serves as a day-to-day working guide for ensuring mechanical systems are safe, efficient, code-compliant, and properly maintained.
If you’re preparing for a mechanical or HVAC contractor licensing exam in Ohio, the 2017 Ohio Mechanical Code (OMC) is one of the core reference materials you need to study. Here’s how to effectively use it in your exam prep:
- Familiarize Yourself with Code Layout
- Practice Open-Book Skills
- Work Through Practice Questions
- Focus on Ohio Amendments
While the 2017 Ohio Mechanical Code (OMC) is primarily a technical document, it includes several visual aids and organizational features that make it more accessible and useful for designers, installers, inspectors, and exam candidates.
- Clear Chapter & Section Organization
- Tables for Quick Reference
- Code Diagrams & Illustrations
- Definitions Section
- Appendix Materials
- Cross-Referencing with Other Codes

2024 Ohio Mechanical Code
$124.99Add to cartThe 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.
