Newark FAQ
Do I need a permit for a residential propane tank?
Tanks larger than 125 gallons water capacity require Fire Marshal plan review and permitting. Smaller tanks must still meet NFPA 58 setback and installation standards enforced statewide.
Who installs propane tanks legally in Delaware?
Only licensed LP-gas installers may install or service propane systems. The State Fire Marshal verifies installer credentials and inspects systems for compliance with NFPA 58 standards.
Wilmington FAQ
Can I store a 20-lb grill propane tank inside?
No. The IFC prohibits storing LP-gas cylinders larger than one pound inside dwellings. Keep grill tanks outside, away from doors and basement vents.
Do permanent propane tanks need a permit?
Yes. Tanks above a threshold size and any commercial installation require a permit from the Delaware State Fire Marshal and inspection by Wilmington Fire.
