How to Apply for a Food Truck Permit in Wisconsin

Before You Apply: Gather Your Documents

Applying for a food truck permit in Wisconsin requires coordinating with multiple agencies. Before submitting any applications, assemble the following documents, as DATCP, local health departments, and other agencies will request them:

• A copy of your Wisconsin business registration from the Department of Financial Institutions (DFI)
• Your federal Employer Identification Number (EIN) or Social Security Number for sole proprietors
• A detailed floor plan of your food truck showing equipment placement, plumbing layout, ventilation, and fire suppression system
• Your proposed menu with a description of how each item is prepared, stored, and held at temperature
• Proof of a commissary kitchen or approved commercial kitchen agreement
• A copy of your commercial vehicle registration
• Proof of commercial general liability insurance (most jurisdictions require at least $1 million per occurrence)
• A valid Certified Food Protection Manager certificate (ServSafe or equivalent ANSI-CFP accredited program)

Step 1: Register Your Business

If you have not already done so, register your business entity with the Wisconsin Department of Financial Institutions. LLCs file articles of organization online through DFI's One Stop Business Portal. Processing typically takes 5–10 business days for standard filings, with expedited options available. Sole proprietors operating under a trade name must file a registration of firm name with the county register of deeds in the county where the business is located. Obtain your federal EIN from the IRS online—it is issued immediately.

Step 2: Obtain Your Sales Tax Permit

Register with the Wisconsin Department of Revenue to collect and remit sales tax. You can apply online through the Department of Revenue's website. The seller's permit is free to obtain. Wisconsin's combined sales tax rate is 5.5% in most counties (5% state + 0.5% county). You are responsible for collecting the correct rate based on where each sale is made. File sales tax returns on time—monthly, quarterly, or annually depending on your tax liability.

Step 3: Secure Your Commissary Agreement

Before applying for your DATCP license and local health department permit, secure a written agreement with a licensed commissary kitchen or approved commercial kitchen. Wisconsin health departments require proof that you have access to a commercial kitchen for food storage, preparation, equipment cleaning, and wastewater disposal. Your commissary agreement must specify the services provided, hours of access, and storage allocated to your operation.

Step 4: Apply for Your Retail Food Establishment License

Contact the local health department where your food truck will be primarily based. They serve as the local agent for DATCP and will process your Retail Food Establishment License application. The process generally involves:

• Completing a mobile food establishment application
• Submitting your truck floor plan, menu, and commissary agreement for plan review
• Paying the annual license fee (varies by jurisdiction, typically $100–$500)
• Scheduling a pre-operational inspection of your fully built-out truck

Major local health departments and their approximate processing times:

• City of Milwaukee Health Department: 2–4 weeks for plan review, plus inspection scheduling
• Public Health Madison & Dane County: 2–3 weeks for plan review; Madison is known for a relatively streamlined process
• Green Bay Health Department: 1–3 weeks for plan review
• Kenosha County Division of Health: 1–3 weeks for plan review
• Appleton Health Department: 1–2 weeks for plan review

Step 5: Pass Your Initial Health Inspection

Once your application and plans are approved, a health inspector will schedule an on-site inspection of your food truck. The inspector will verify compliance with ATCP 75 (Wisconsin Food Code) standards, including:

• Hot and cold holding equipment maintains proper temperatures (below 41°F for cold, above 135°F for hot)
• A dedicated handwashing sink with hot and cold running water, soap, and single-use towels
• A three-compartment sink or mechanical dishwasher properly installed
• Adequate wastewater and grease disposal systems
• Food contact surfaces that are smooth, non-porous, and easily cleanable
• A properly installed and certified fire suppression system
• Valid Certified Food Protection Manager certificate available for review

If your truck passes, your license is issued within a few days. If corrections are needed, you will have a specified period to address them before re-inspection.

Step 6: Obtain Fire Department Clearance

Schedule a fire safety inspection with the fire department in your primary city of operation. Bring documentation of your fire suppression system installation and most recent service date, proof of fire extinguisher certification, and propane system inspection records. Some jurisdictions issue a separate fire safety permit, while others provide a clearance letter attached to your health department file.

Step 7: Apply for City-Specific Permits

If you plan to vend in specific cities, check whether additional municipal permits are required. Milwaukee requires a mobile food vendor license through the city's licensing division. Madison has a well-structured mobile food vending permit system with designated locations near the Capitol Square and UW-Madison campus. Green Bay may require special event permits for vending near Lambeau Field during Packers games and events. These city permits are in addition to your DATCP-administered license.

Renewal and Ongoing Compliance

Your Retail Food Establishment License must be renewed annually through your local health department. Renewal typically requires passing a routine inspection and paying the renewal fee. Keep your seller's permit active by filing sales tax returns on time with the Wisconsin Department of Revenue, even during winter months when you may have no sales. Maintain your Certified Food Protection Manager certificate current—it is valid for five years but must be renewed before expiration to avoid a lapse in compliance.
