McNairy County HVAC Permit Requirements
In McNairy County, Tennessee, HVAC permit requirements are determined by local jurisdiction. While state laws establish the framework for building codes and permit enforcement, individual counties and municipalities have the authority to adopt, amend, and administer their own code programs. This means that permit requirements, including thresholds, fee schedules, and inspection protocols, can vary across different areas within Tennessee.
For properties located in unincorporated areas of McNairy County, it is essential to verify specific local requirements. While the state provides a list of counties where a state residential building permit is required in unincorporated areas, it is always recommended to consult directly with the local government to determine if any local permits are necessary before commencing construction.
McNairy County does not appear to have a centralized "Building & Safety Division" readily advertised for general inquiries. However, the Town of Selmer, within McNairy County, has a Building Inspector and Code Enforcement officer, Brandon Vaughan, who can be contacted for building-related questions.
It is important to note that a state HVAC contractor license does not automatically satisfy local permit requirements. A licensed contractor must still obtain the necessary local permits, as permit issuance is a separate administrative act by the local authority having jurisdiction.

State Statutes and Adopted HVAC Codes
In Tennessee, building construction safety standards, including those for HVAC systems, are authorized under Tennessee Code Annotated (T.C.A.) ยงยง 68-120-101, et seq. The state adopts minimum statewide building construction safety standards through the Tennessee Department of Commerce and Insurance, Division of Fire Prevention. As of the most recent updates, the state has adopted the 2021 editions of the International Code Council (ICC) family of codes, which include the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC) for HVAC-related installations. It is important to note that Tennessee is a "home rule" state, meaning local jurisdictions may adopt and enforce their own building codes, which may differ from the state-level standards or utilize different editions of the model codes.
Primary State Agency
The primary agency responsible for setting and enforcing these statewide standards is the Tennessee Department of Commerce and Insurance, specifically through the State Fire Marshal's Office (SFMO) and its Codes Enforcement section. The SFMO oversees the adoption of the minimum statewide building construction safety standards and provides enforcement in areas of the state that do not have local building code programs or where the local government has opted out of enforcing its own codes.
