Propane (LPG) storage in Rialto is governed by Cal. Fire Code Chapter 61 (Liquefied Petroleum Gases), adopted by reference under Rialto Mun. Code Ch. 15.28. Residential propane cylinders ≤2.5 lb. propane each are essentially unregulated; storage beyond that triggers permit, setback, and placement rules. Commercial/industrial bulk storage above 125 gal. requires a Rialto Fire operational permit and engineered separation distances.

Ontario FAQ
Do I need a permit for a 100-gallon tank?
Most residential tanks at or below 125 gallons do not require a permit, but defensible-space setbacks still apply. Confirm with SBCFPD before installing.
Can I store extra tanks in my garage?
No. Indoor storage of LP gas is restricted under the Fire Code. Tanks must be outside on a noncombustible pad with required clearances and ventilation.
Rialto FAQ
Can I store extra propane tanks at my Rialto home?
Yes — up to 2 cylinders (typically 20-lb. BBQ size) stored outdoors, upright, at least 10 ft. from doors/windows and 5 ft. from your property line. Never indoors, in a garage that opens to living space, or on a roof/basement.
Do I need a permit for a propane tank?
Not for typical residential BBQ cylinders. Aggregate storage above 720 lb. (~125 gal., e.g., a stationary tank for a forklift fleet or rural home heating) requires a fire operational permit from Rialto Fire under CFC §105.5.30.
Can I refill my own propane tank at home?
No. Cylinder filling must occur at a permitted LPG dispensing facility per CFC §6107 — refilling at home is prohibited.
