Honolulu FAQ
How many propane tanks can I store?
Most homes may keep two 20-pound grill cylinders outdoors with proper spacing. Quantities approaching aggregate IFC limits or any installed tank over 125 gallons triggers HFD permit review.
Can I store propane in my garage?
Indoor storage of LP-gas cylinders is generally prohibited under the IFC. Keep cylinders outdoors, upright, shaded, away from drains, and at least 10 feet from ignition sources.
Waipahu FAQ

Yes. Aggregate LP-Gas installations of 125 gallons water capacity or more require plan submittal to HFD and must satisfy NFPA 58 installation standards.
Is a small cylinder at home subject to plan review?
No. Typical 20-pound BBQ cylinders do not trigger plan review but must be stored upright, outdoors, away from ignition sources per NFPA 58.
