Propane (LP-gas) storage in Wilmington follows the International Fire Code adopted by Delaware. Residential cylinders are capped at small quantities; larger tanks need permits from the State Fire Marshal.
Delaware adopts the International Fire Code (IFC) statewide through the State Fire Marshal's office under Title 16 §6601. Wilmington Code Ch. 13 incorporates these rules and authorizes WFD to inspect commercial and multifamily propane installations. Residential users may store small portable cylinders for grilling but cannot keep large cylinders inside dwellings. Permanent tanks require setbacks from buildings and property lines, and installations over a threshold size require permits from the State Fire Marshal. Storage near means of egress, basements, and stairwells is prohibited.
WFD issues correction notices; State Fire Marshal can shut down non-compliant installations. Fines escalate for repeat violations.
