| IMC — International Mechanical Code | 2021 IMC — statewide, adopted by the State Fire Marshal's Office. NOT the 2024 IMC. Tennessee's statewide construction standards are a floor that a municipality can displace: under T.C.A. 68-120-101 et seq. a city may certify that it has adopted and adequately enforces its own current ICC Residential, Building and Fire codes (audited by the SFMO at least every three years), and the state code re-applies if the local codes fall more than seven years out of date or enforcement is found inadequate; municipalities may also exempt one- and two-family dwellings by a two-thirds vote of the governing body, the exemption lapsing 180 days after the next general municipal election unless renewed. So the 2021 IMC is what governs where no qualifying local code is in force. | Tenn. Comp.
