How Tennessee adopts the IFC
The State Fire Marshal’s Office (Dept. of Commerce and Insurance) adopts model-code editions by rulemaking under T.C.A. 68-120-101 (chapters 0780-02-01 NEC, 0780-02-02 building/fire/energy, 0780-02-23 residential), filing with the Secretary of State. No legislative approval step was found; the General Assembly constrains content by statute (for example no mandatory sprinklers in one- and two-family dwellings, 2/3 local vote for local sprinkler mandates) and in 2025 Public Chapter 149 carved a roof-reflectance requirement out of the 2021 IECC.
Cycle. Irregular, roughly every 4 to 8 years and not every code at once: NEC 2017 since 2018; residential IRC/IECC 2018 since 2020; IBC/IFC/commercial IECC 2021 since 2025.
