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.
