Knoxville City Code Chapter 16 incorporates Tennessee fire-code standards for residential propane storage, capping tank size at homes, requiring setbacks from buildings and ignition sources, and giving Knoxville Fire Department authority to inspect installations.
Residential propane storage in Knoxville is governed by Chapter 16 of the City Code, which incorporates the Tennessee adoption of national fire codes for liquefied petroleum gas. Standard 20-pound grill cylinders may be stored outdoors but should not be kept inside dwellings or attached garages. Larger stationary tanks for whole-home heating require permits, professional installation, and minimum setbacks from buildings, property lines, ignition sources, and openings. Knoxville Fire Department Fire Prevention Bureau inspects new installations and can order corrections. Knox County rules and TN State Fire Marshal regulations apply outside city limits and to commercial storage.
Improper indoor storage, undersized setbacks, or unpermitted large tanks can lead to red tag orders, fines, removal requirements, and liability for any resulting fire or explosion damage.
