HVAC Permit Requirements in Unincorporated Areas
Properties located in the unincorporated areas of Clinton County fall under the jurisdiction of the Clinton County Building & Zoning Department. When planning HVAC work, it is important to note the following:
- Permit Necessity: While some minor renovations may not require a zoning permit, building permits are generally required for structural and mechanical installations. You should contact the Building & Zoning Department directly to verify if your specific HVAC project requires a building permit.
- Zoning Permits: A zoning permit is required for most structures and additions in zoned townships. However, HVAC installations are typically exempt from the $60 zoning permit fee, provided they do not increase the existing footprint of the structure.
- Inspections: HVAC work is subject to inspection. For example, during rough-in inspections, all ductwork and cold air returns must be completed.
- Plan Requirements: For commercial projects, detailed drawings including HVAC plans are required as part of the permit application process.
- Unzoned Townships: Clark and Washington townships are unzoned and do not have county zoning regulations, but building permits are still required for construction work in these areas.

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.
