Minnesota State Fire Code, adopted from the 2020 IFC, governs propane storage in Hennepin County. Residents may store cylinders up to 100 pounds outdoors with setbacks; larger tanks require fire marshal review and a city building permit.
Hennepin County cities follow the Minnesota State Fire Code (MSFC), which adopts NFPA 58 for liquefied petroleum gas. Residential propane cylinders up to 100 pounds water capacity may be stored outside in well-ventilated locations away from ignition sources, with NFPA-required setbacks of typically five to 10 feet from windows, doors, and air intakes. Larger residential tanks, such as 500 or 1,000 gallon installations common in outer Hennepin County, require permits, professional installation, and inspection by the local fire marshal. Indoor storage of propane cylinders larger than one pound is generally prohibited in occupied dwellings.
Improper indoor storage, exceeding cylinder size limits, or installing a large tank without permits can lead to fire-marshal removal orders, misdemeanor charges, and fines that frequently exceed 500 dollars per violation.
