Full Breakdown

Propane storage and use is governed by the adopted International Fire Code and Illinois LP Gas Safety rules administered by the State Fire Marshal. For one- and two-family dwellings, standard grill cylinders are allowed, but the fire code bars open-flame cooking devices using cylinders larger than the exempt 1-pound capacity from combustible balconies or within 10 feet of combustible construction (with limited exceptions). Larger stationary tanks (for heating or rural homes) must meet NFPA 58 clearances from buildings, property lines, and ignition sources based on tank size. Filling, transport, and installation of bulk LP tanks require licensed handlers under state law.

Violations & Fines

Improper LP-gas storage is a fire-code violation subject to correction orders and penalties; unlicensed handling of bulk propane violates Illinois LP Gas Safety rules.
