Delaware city permit guide
Wilmington food trucks usually need to coordinate Delaware One Stop business licensing and gross receipts registration, Delaware Division of Public Health mobile food unit review, service-area or commissary records, New Castle County local routing, Wilmington food truck registration and site approval, and fire review for propane, generators, fryers, or cooking equipment.

Permit checklist
Start with the address and use of the space. New openings, remodels, ownership changes, alcohol service, mobile operations, and special equipment can each add requirements.
Also connected to: One Stop, Division of Revenue license, gross receipts tax, filing frequency
Food trucks should register through Delaware One Stop for the correct business license and confirm gross receipts tax, local tax overlap, exemption records, marketplace or delivery-platform handling, and filing frequency.
Also seen as: mobile food permit, food truck health permit, mobile food unit plan review
Delaware mobile food units should confirm DPH mobile food unit plan review, menu/equipment details, application and fee handling, service-area documentation, pre-operational inspection, annual permit, and local routing.
Also connected to: county permit routing, food establishment review, temporary food, local inspection
Wilmington food trucks should keep health permit and inspection records ready, including menu, equipment, approved sources, potable water, wastewater, service-area or commissary records, and temporary-event documents.
Also connected to: base of operations, service area, potable water, wastewater, cleaning, storage
Roaming Delaware mobile food units should verify service-area or commissary support, potable water, wastewater disposal, warewashing, food storage, route/event records, and cleaning/restocking access before operating.
Also connected to: food truck registration, vendor approval, site map, private-property permission, local license
Wilmington treats food truck registration and approved operating sites as a separate local layer. Food trucks should confirm city registration, site applications, private-property permission, event rules, insurance, hours, parking, and renewal timing.
Also connected to: propane, generators, hood suppression, extinguishers, fryers, open flame
Food trucks using propane, generators, fryers, open flame, or grease-producing cooking equipment should track State Fire Marshal or local fire review separately from health, tax, and vendor approvals.
Why it gets missed
Delaware One Stop registration, DPH mobile food review, county routing, Wilmington registration, and fire review are separate checks.
Mobile units should keep water, wastewater, cleaning, restocking, storage, and support-location records ready for inspection.
A state food permit does not replace Wilmington food truck registration, site application, event, private-property, parking, or right-of-way rules.
LP-gas, generators, fryers, and grease-producing cooking equipment can add fire inspection and operational safety records.
