Tustin, CA Fire Regulations: Propane Storage (2026)

There is no Tustin-specific propane ordinance; storage and use of liquefied petroleum gas (LP-gas) are governed by the California Fire Code, which the Orange County Fire Authority (OCFA) enforces as Tustin's fire agency. Chapter 61 of the California Fire Code covers liquefied petroleum gases. For everyday residential use, the practical limits are: the quantity of LP-gas stored outside without additional safeguards is generally limited to 20 pounds (about 9 kg) per container in many situations, and outdoor storage of cylinders awaiting use or exchange must follow the code's location and separation tables (Table 6109.x). Cylinder valves must be protected by screw-on caps or collars and kept securely in place whether the cylinder is full, partly full, or empty, and stored cylinders must be protected against tampering, typically in a suitable enclosure. General safety practice reflected in fire-agency guidance is to store propane cylinders outdoors in an upright (vertical) position, never indoors or in an enclosed space such as a basement, garage, shed, or tent, and never to keep a spare cylinder under or beside a barbecue grill. Larger quantities, fixed tanks, or commercial LP-gas storage trigger permit requirements and stricter siting rules from OCFA. Homeowners replacing or exchanging a standard 20-pound barbecue tank are within the routine-use range, but should confirm any permit needs with OCFA for multiple cylinders, larger tanks, or installations.
