What Tennessee Building Code Editions Are Adopted:

  • 2012 International Building Code (IBC)
  • 2017 National Electric Code (NEC)
  • 2009 International Residential Code (IRC)
  • 2012 International Energy Conservation Code (IECC), 2009 IRC Chapter 11 also accepted

Individual jurisdictions may adopt more recent model codes or more stringent codes.  Thirty local jurisdictions have been granted exemptions and are authorized to perform independent plans reviews. The City of Athens and Shelby County, for example both enforce the NEC-2014.

Applicability (statewide, local, limited): LIMITED

There is a statewide residential code enforcement program that came into effect in 2010, which individual cities and areas can “opt out” of, but if they don’t, state permits are required for residential construction (and state will provide enforcement). Individual jurisdictions adopt their own codes (commercial included); the state code based on the 2012 IBC is applicable to all structures, but enforcement in terms of plan review and inspection only applies to certain occupancies. State codes may be amended locally to be more restrictive than the state code; jurisdictions that do not rely on the state for enforcement and larger jurisdictions may “opt out” (they are “exempt” jurisdictions) and adopt any code they want, as long as it’s within 7 years of the most current edition of the I-codes. Most major jurisdictions have adopted more current editions of the International Codes.
