Tanks up to 125 gallons must be at least 5 feet from buildings, property lines, and ignition sources. Larger tanks require 10 to 25 foot clearances per NFPA 58.
Can I store propane cylinders inside my Arizona garage?
Generally no. NFPA 58 limits indoor storage to one cylinder of one pound or less. Larger cylinders must be stored outdoors or in approved ventilated enclosures.
Tucson FAQ
Can I keep spare propane tanks in my garage?
No. The IFC, as adopted by Tucson, prohibits storing LP-gas cylinders inside attached garages or living spaces. Keep them outdoors, upright, shaded, and away from ignition sources.
