Chattanooga enforces the Tennessee-adopted International Building and Fire Codes for sprinklers, requiring NFPA 13 systems in most new commercial, multifamily, and assembly buildings, with annual inspection by licensed contractors.
Chattanooga has adopted the International Building Code and International Fire Code through Tennessee’s state codes program, applied locally under CCO Chapter 6. New apartment buildings of three or more stories, hotels, schools, assembly occupancies, and most commercial structures over the IBC area thresholds must install NFPA 13 or 13R automatic sprinkler systems. Existing buildings undergoing major renovation or change of use are also pulled into sprinkler requirements. Annual inspection, testing, and maintenance under NFPA 25 is required, performed by Tennessee-licensed sprinkler contractors. Single-family homes are not required to sprinkler.
Operating a covered occupancy with an out-of-service or untested sprinkler system can trigger CFD correction orders, certificate-of-occupancy holds, and daily fines.
