Plumbing Code Adoption in Tennessee
The State of Tennessee adopts the International Plumbing Code (IPC) as its statewide baseline technical standard for plumbing systems. As of the most recent state-level updates, the 2021 edition of the International Plumbing Code is the primary standard adopted by the Tennessee State Fire Marshal's Office for statewide building construction safety. It is important to note that while the state establishes these minimum standards, local jurisdictions (counties and municipalities) may adopt and enforce their own codes, provided they are equal to or more stringent than the state-adopted baseline.

Plumbing regulation in Tennessee is managed through a multi-layered framework involving several key entities:
- Tennessee State Fire Marshal's Office (SFMO): Operates under the Department of Commerce and Insurance and is responsible for adopting and maintaining the minimum statewide building construction safety standards, including the IPC.
