Verify locally. Tennessee sets a statewide minimum residential code (2018 IRC + IECC with state amendments) but lets each city/county adopt stricter editions — Nashville moved to the 2024 I-Codes in July 2025 while Memphis remains on the 2018 cycle. In areas with no local code office, the State Fire Marshal’s CORE program issues permits. Always confirm the edition enforced at your address.
