Montgomery County HVAC Permit Requirements
In Montgomery County, Ohio, a mechanical permit is required for the installation, alteration, repair, or replacement of HVAC systems, including heating, ventilation, and air conditioning equipment and ducts. This applies to both residential and commercial properties. Properties in unincorporated areas of Montgomery County fall under the jurisdiction of the Montgomery County Building Regulations Division for these permits.
The county enforces building codes, flood damage prevention regulations, and airport zoning requirements around Wright-Patterson Air Force Base. For HVAC work, compliance with the Ohio Mechanical Code (OMC), the International Mechanical Code (IMC), International Fuel-Gas Code (IFGC), and the International Residential Code (IRC) is required, as appropriate.
Homeowners or contractors can apply for permits. For HVAC work, licensed contractors are generally required, as Ohio has an Occupational Licensing Board (OCILB) for HVAC, electrical, and plumbing trades. However, homeowners may be able to obtain permits for HVAC work on their own property by signing an affidavit and performing the work themselves, though they must possess a valid license for heating work.
Permit applications, including necessary plans and supporting documents, are typically submitted through an online portal. After permit issuance, all required inspections must be scheduled and completed before final approval.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Montgomery County, the Montgomery County Building Regulations Division is the primary authority for issuing HVAC permits. This division enforces state building codes and local ordinances. It is important to identify any specific zoning requirements of the local township or village where the property is located, as these may also need to be addressed.
The process generally involves submitting an application and plans through the county's online portal, responding to any comments, paying fees, and scheduling required inspections. While the county handles building and mechanical permits, zoning clearance is typically managed by the respective township or village zoning official if zoning exists in that unincorporated area.

Ohio HVAC Building Codes and Legislation
The state of Ohio regulates heating, ventilation, and air conditioning (HVAC) systems through a comprehensive framework of building codes. As of March 1, 2024, Ohio has adopted the 2024 editions of its state building codes, which are based on the 2021 International Codes (I-Codes) published by the International Code Council (ICC), modified with specific Ohio amendments.
Key components of this regulatory framework include:
- Ohio Mechanical Code (OMC): This code governs the design, installation, and maintenance of mechanical systems, including ductwork, combustion air, exhaust systems, hydronic piping, boilers, and refrigeration. It is based on the 2021 International Mechanical Code.
- Ohio Building Code (OBC): This code covers structural and fire-safety aspects that intersect with HVAC, such as equipment clearances, shaft construction, and fire/smoke damper requirements. It is based on the 2021 International Building Code.
- Residential Code of Ohio (RCO): This code provides the standards for one-, two-, and three-family dwellings.
- Statutory Authority: The legal foundation for these construction standards is established in Chapter 3781 of the Ohio Revised Code (ORC).
Primary Regulatory Agency
The Ohio Board of Building Standards (BBS), which operates under the Ohio Department of Commerce, is the primary agency responsible for adopting and amending the state's construction codes. The Board is tasked with establishing the rules that govern the erection, construction, repair, and alteration of buildings across the state. While the BBS sets these statewide standards, enforcement is often carried out by certified local building departments.
