How to Start a Food Truck Business in Delaware: DPH Mobile Unit Plan Review, Restaurant Retailer License and Local Permits

Starting a food truck in Delaware requires navigating both state-level food safety regulations and local municipal permits. Unlike states with county health departments, Delaware operates under a unified state framework: the Department of Health and Social Services, Division of Public Health (DPH), Office of Food Protection oversees all mobile food units. Combined with Delaware's business license requirement and local jurisdiction rules, the process is systematic but involves multiple agencies. This guide walks you through each step.

What You Need: Food Truck Equipment and Vehicle

Before you file any permits, you'll need a functional mobile food unit. This is not just a vehicle, it's a commercial kitchen on wheels that must meet DPH standards.

Essential Equipment and Materials

• Vehicle: A food-service-grade truck or trailer (new or used) with adequate insulation and ventilation. The vehicle must be safe and able to transport cooking equipment and food safely.
• Cooking equipment: Commercial-grade stove, grill, fryer, or other cooking appliances depending on your menu. All equipment must be NSF-certified or equivalent.
• Food storage: Refrigerated units (reach-in coolers, under-counter units, or walk-in coolers depending on volume). Temperature monitoring thermometers for all cold storage.
• Handwashing station: A dedicated sink with hot and cold running water, soap, and paper towels. This is non-negotiable for DPH approval.
• Three-compartment sink: Required for washing, rinsing, and sanitizing dishes and utensils. Must have hot water capability.
• Waste disposal: Grease trap or interceptor (if required by local jurisdiction), wastewater containment, and trash receptacles.
• Utensils and single-service items: Food prep utensils, serving utensils, plates, cups, napkins. DPH requires single-service articles for customers.
• Food thermometers: Calibrated thermometers for checking internal food temperatures. Proper cooking temperatures are non-negotiable for food safety.
• Labels and storage: Proper containers and labels for all food items, including date-marking for prepared foods.
• Cleaning supplies: Food-safe sanitizers, cleaning cloths, and chemicals suitable for a commercial kitchen.

Your total equipment investment depends on the truck size, new versus used, and the complexity of your menu.

Step-by-Step: Forming Your Food Truck Business in Delaware

Step 1: Decide on Your Business Structure (Optional but Recommended)

You can operate as a sole proprietor, but most food truck owners choose to form an LLC for liability protection. This step is optional but advisable.

For an LLC: File a Certificate of Formation with the Delaware Division of Corporations. The filing fee is $110. Your LLC name must include "Limited Liability Company," "LLC," or "L.L.C." You can file online through the eCorp Document Upload Service. Delaware does not require an annual report for LLCs, but you will owe a flat annual tax of $400 due each June 1 (check corp.delaware.gov for the current amount and effective date). Processing time varies; expedited options start at $50 for next business day service.

For a Corporation: File a Certificate of Incorporation (filing fee $109). Corporations must file an Annual Franchise Tax Report by March 1 each year (fee $50).

Sole Proprietor: If you operate under your own name, skip this step and move to Step 2.

Step 2: Check Your Local Jurisdiction's Food Truck Rules

This is critical: municipal rules vary significantly across Delaware's 57 incorporated places and 3 counties. No general county license exists, so you must check with your specific city or town.

Wilmington: Pushcart and mobile vendor permits are issued by Licenses and Inspections for specific locations (Market Street Mall, Second to Seventh Streets are common spots). Contact Wilmington Licenses and Inspections for current fees and location availability.

Dover: The City of Dover requires a City of Dover business license for food vendors. Contact the City to confirm current fees.

Middletown, Rehoboth Beach, Dewey Beach, Lewes, and other towns: Each has its own mobile vendor or food truck rules. Call or visit your town's municipal office to ask about permits, fees, and any location restrictions before you invest heavily.

Some municipalities may restrict where you can operate (e.g., specific neighborhoods or markets only), require additional liability insurance, or charge location-specific fees. Clarifying this early saves time and money.

Step 3: Register for a Delaware Business License

Every person or business conducting a trade in Delaware must obtain a business license from the Division of Revenue. Apply through Delaware One Stop.

License category: Food trucks are almost certainly classified as "restaurant retailer" (take-out food service is a restaurant retailer under 30 Del. C. 2906(a)), but confirm with the Division of Revenue. The Division may classify your truck differently based on your specific menu and operation.

License fee: $75 for the first location. Each additional location (if you later operate multiple trucks) costs $25 per location. Licenses expire December 31 annually; fees are prorated by full calendar months for the first year.

Gross receipts tax: In place of sales tax (Delaware has no sales tax), you will owe gross receipts tax at 0.6472% of receipts after a $100,000 monthly deduction. This is filed monthly or quarterly (new businesses file quarterly). Ask the Division of Revenue to confirm the exact tax rate and filing requirements for your food truck classification.

Operating without a license: Carries a fine of up to $3,000 or up to two years in prison, so this is not optional.

Step 4: Submit Your Mobile Unit Plan Review to DPH

This is the state food safety inspection. The Department of Health and Social Services, Division of Public Health, Office of Food Protection must review and approve your mobile unit design before you operate. Contact the Office of Food Protection to request the mobile unit plan review packet.

What to provide:

• Detailed schematic or blueprints of your food truck layout, showing all equipment, handwashing station, three-compartment sink, and food storage areas.
• A list of all cooking and refrigeration equipment (model numbers and NSF certifications if available).
• Information about your servicing facility: the physical street address in Delaware where you will clean, restock, and prepare food before each operating day. This must be a licensed, commercial kitchen (such as a shared kitchen facility, a restaurant's prep area, or your own commercial space). DPH will verify that this facility is approved for food preparation.
• Your operating plan (days and locations where you intend to operate).

Plan review fee: Per 16 Del. C. 122(3)u, the fee is based on floor area: $50 for 1,000 square feet or less, $100 for 1,001 to 5,000 square feet, up to $250 above 15,000 square feet. A small mobile unit would fall in the lowest tier, but check with the Office of Food Protection for the fee that applies to a mobile unit when you request the plan review packet.

What DPH is checking: Proper ventilation, adequate handwashing facilities, correct three-compartment sink setup, food storage separation (raw from ready-to-eat), thermometer placement, and equipment NSF certification. If DPH finds issues, they will request modifications before approval.

Step 5: Obtain Your Annual Public Eating Place Permit

Once your plan review is approved, you apply for the annual food service permit. The permit fee in statute is $100 (check with the Office of Food Protection for the exact current amount on your invoice).

What this covers: Authorization to operate as a licensed food establishment. This permit must be conspicuously displayed in your truck.

Step 6: Set Up Your Servicing Facility

Your mobile unit plan must identify a fixed facility in Delaware where you will wash equipment, store ingredients, and prepare food before service. This servicing facility must:

• Be a licensed commercial kitchen (not a home kitchen).
• Have its own food service license or be part of an existing licensed establishment.
• Be located in Delaware.
• Have adequate cold storage, handwashing, and food prep space for your daily needs.

Options include renting space at a shared commercial kitchen facility, arranging prep access at an existing restaurant, or building out your own commercial kitchen. DPH will verify this facility's compliance before approving your mobile unit.

Step 7: Compliance and Ongoing Requirements

Annual license renewal: Your Delaware business license and DPH permit must be renewed annually. Business license renewal is through Delaware One Stop; food service permit renewal is through DPH. Check with each agency for its renewal timing so you never operate on an expired license or permit.

Food safety standards: You must maintain proper food storage temperatures, follow internal cooking temperatures for all foods (check FDA guidelines), practice proper cross-contamination prevention, and ask the Office of Food Protection which temperature records you must keep.

Gross receipts tax filing: File your monthly or quarterly gross receipts tax return with the Division of Revenue. Underreporting or failing to file can trigger audits and penalties.

Temporary events (up to 14 days): If you want to operate at county fairs, farmers markets, or festivals for up to 14 days per year without a permanent location, you may qualify for a temporary food establishment permit. Apply at least 10 days before the event. Check with DPH for the specific requirements and any fee.

Tips and Common Mistakes to Avoid

• Do not skip the local jurisdiction check: Many prospective food truck owners assume state-level approval is all they need. The result: they buy a truck, invest in equipment, then learn their chosen municipality does not allow mobile food units or charges a high permit fee. Confirm local rules before purchasing your truck.
• Do not skip the servicing facility: DPH will not approve your mobile unit without an identified, compliant servicing facility. This is not optional and is a common reason for rejected plans.
• Do not assume county health department involvement: The state, not a county, oversees mobile units: DPH (state level) handles them. Do not contact a county office expecting help; contact the Division of Public Health, Office of Food Protection.
• Do not neglect the three-compartment sink: This is not optional. It must be sized, plumbed, and supplied correctly. A rejection at plan review because of inadequate or missing three-compartment sink is preventable with proper design.
• Do not operate without a business license: Delaware enforces this strictly. The penalty is severe. Always apply through Delaware One Stop before your first day of operation.
• Do not underestimate gross receipts tax: If you classify as "restaurant retailer," you owe 0.6472% on all revenue above $100,000 per month. Failing to file or underreporting can trigger audits. Keep detailed daily sales records.
• Do not overspend on equipment before permits are approved: Apply for permits and secure approvals before you buy all your equipment. Changes required by DPH could make some equipment unsuitable or require replacements.

Expected Results, Timeline, and Costs

Timeline from start to first day of operation: Timing varies with your vehicle build, DPH plan review, and local permits, so ask each agency for its current turnaround before you commit to an opening date.

Why the delay: DPH plan review is not instant. The Division of Revenue may request clarification on your license application. Your servicing facility may require inspections. Local jurisdiction permits add time depending on the municipality.

Total startup cost estimate:

• Vehicle and equipment: your largest expense, which depends entirely on what you buy
• DPH plan review fee: set by floor area under 16 Del. C. 122(3)u (check with the Office of Food Protection)
• DPH annual food service permit fee: $100 in the statute (check with the Office of Food Protection for the amount on your invoice)
• Delaware business license: $75
• LLC formation (if applicable): $110 plus annual $400 tax starting in 2027
• Local permits: check with each city or town
• Servicing facility: depends on your arrangement
• State fees you can count on: $75 business license plus $110 if you form an LLC, plus the DPH fees above and local permits

Operating expenses (food, fuel, insurance, labor) are separate and depend on your menu and scale.
