Planning to operate a food truck or food trailer in Denver, Colorado? Whether you’re building your first mobile kitchen or expanding into the Denver market, understanding the city’s inspection and permit requirements is essential before you can start serving customers. Denver has its own licensing system managed through multiple city departments, and as of 2026, a new statewide reciprocity law has simplified operations across Colorado.
This guide covers everything you need to know about passing your food truck inspections in the City and County of Denver — from the permits you’ll need, to fire safety requirements, health department standards, and the commissary kitchen rules that trip up many first-time operators.
Overview: Denver’s Multi-Department Permit Process
Unlike some cities where a single agency handles food truck licensing, Denver requires coordination across three departments. Each one handles a different piece of the puzzle, and you’ll need approvals from all three before you can legally operate:
- Department of Excise and Licenses — Issues the Retail Food Establishment-Mobile license (your primary business license to operate a food truck in Denver)
- Denver Fire Department — Conducts fire safety inspections and issues the Flammable Operational Permit for propane-powered units
- Denver Department of Public Health & Environment (DDPHE) — Reviews your mobile plan, inspects food safety practices, and ensures health code compliance
The process begins with Excise and Licenses. You must submit a complete Mobile Plan Review application to them before either the Fire Department or DDPHE will schedule an inspection.
Permits and Licenses Required
Here is the full list of permits and licenses you’ll need to operate a food truck or food trailer in Denver:
1. Retail Food Establishment-Mobile License
This is your core license from the City and County of Denver, required for all food trucks, food trailers, and food carts operating within city limits. The annual cost ranges from $200 to $350 depending on the type and size of your operation. Processing can take up to 30 days during the busy season (spring and summer), so plan ahead.
2. Denver Fire Department Flammable Operational Permit
If your food truck uses propane (which approximately 80% of food trucks do), you’ll need this permit. The annual cost is $200, and it requires passing a fire safety inspection. If your unit does not use propane or any flammable fuels, you can obtain a free exemption letter instead. If you fail your first inspection, reinspection costs $100.
3. Zoning Permit for Private Property
If you plan to park and operate on private property, you’ll need a zoning permit at $50 per year. This ensures your chosen location is properly zoned for mobile food vending.
4. Colorado Sales Tax License
Required for collecting and remitting sales tax. You can register for free online through the Colorado Department of Revenue.
5. Food Handler Certifications
Every employee who handles food must obtain a Food Handler’s License within 30 days of being hired. Additionally, at least one person on your team should hold a Food Safety Manager Certification (typically $50–$150), which is required during the application process.
6. Commissary Kitchen Agreement
You must have a signed agreement with a licensed commissary kitchen. More on this critical requirement below.
Estimated First-Year Costs
Here’s a realistic breakdown of what you should budget for permits and operational costs in your first year of operating a food truck in Denver:
- City mobile food license: $200–$350/year
- Fire Department propane permit: $200/year
- Zoning permit (private property): $50/year
- Food Safety Manager certification: $50–$150
- Commissary kitchen rental: $200–$800/month ($2,400–$9,600/year)
- Insurance: $1,800–$4,200/year
- Total estimated first-year costs: $3,900–$13,750 (excluding the truck itself)
Fire Safety Inspection: What Denver Fire Department Looks For
Denver will not issue or renew your food truck license without proof of a passed fire inspection. This is one of the most common points where new operators get held up, so it’s worth understanding exactly what the Denver Fire Department checks.
Propane System Requirements
- Maximum LP-gas capacity: 200 pounds (for example, two 100-lb tanks or equivalent)
- All gas piping must run under the vehicle, below any insulation or false bottom
- Piping must enter the vehicle through the floor directly beneath or adjacent to the appliance it serves
- A clearly labeled propane shutoff valve is required — signage must use 2-inch red letters on a white background
- All connections must be leak-free (inspectors will test for leaks)
Fire Suppression System
- A Type I commercial kitchen hood with an automatic fire suppression system is required for any cooking that produces grease-laden vapors
- The suppression system must be professionally installed and inspected by a third party before the Denver Fire Department will conduct their inspection
- A portable fire extinguisher (minimum 2A:10BC rated) must be mounted and easily accessible

- Generator installations must be ventilated and secured
- No exposed or damaged wiring
To schedule a fire inspection, contact the Denver Fire Department at 720-913-3474 or email DFDmobiles@denvergov.org. You’ll need to submit your unit specs before they schedule the inspection.
Health Department Inspection: DDPHE Requirements
The Denver Department of Public Health and Environment (DDPHE) conducts the health and food safety portion of your inspection. An Environmental Health Specialist will review your menu, ask questions about your food preparation procedures, and then physically inspect your mobile unit and equipment.
Key Areas DDPHE Inspects
- Handwashing station: A dedicated handwashing sink with hot and cold running water, soap, and paper towels is mandatory. This must be separate from your food prep and dishwashing sinks.
- Food storage and temperature control: Proper refrigeration for all perishable items. Hot-holding equipment must maintain food at 135°F or above. Cold items must be held at 41°F or below.
- Three-compartment sink: Required for washing, rinsing, and sanitizing dishes and utensils.
- Waste disposal: Proper gray water containment and disposal system. Liquid waste cannot be discharged on the ground.
- Food preparation surfaces: All surfaces must be smooth, non-absorbent, and easily cleanable. Stainless steel is the industry standard.
- Pest control: Screens on windows and openings, proper food storage to prevent contamination.
- Employee hygiene: Evidence of proper handwashing procedures, hair restraints, and clean uniforms.

The Commissary Kitchen Requirement
One of the most important requirements that catches new food truck operators off guard is the commissary kitchen mandate. In Denver, a commissary is defined as a facility approved by DDPHE where food, containers, or supplies are kept, handled, prepared, packaged, or stored — and that operates in compliance with all applicable regulations.
By default, your food truck must physically report to your commissary every operating day for servicing, restocking, and maintenance. This means you need a signed commissary agreement before you can even apply for your license.
Can You Operate Without Daily Commissary Visits?
Yes, but your truck must be fully self-contained. If you want to skip daily commissary reporting, your food truck or trailer must include all of the following onboard: a mop sink, a food preparation sink, a three-compartment sink, adequate cooking equipment, and sufficient storage. The decision on whether your unit qualifies is at the discretion of DDPHE.
This is one of the reasons why investing in a well-designed, fully-equipped food truck from the start can save you significant ongoing costs — a properly built truck with all required sinks and equipment may eliminate the need for a $200–$800/month commissary rental.
2026 Game-Changer: Colorado License Reciprocity (HB25-1295)
As of January 1, 2026, Colorado House Bill 25-1295 created full license reciprocity between Denver and the rest of the state. This is the biggest regulatory change for food truck operators in years. Here’s what it means for you:
- A Denver Retail Food Establishment-Mobile license is now accepted across all Colorado jurisdictions
- Similarly, a Colorado state license (CDPHE) is now accepted in Denver
- You only need to send a copy of your license to a new jurisdiction at least 14 days before you plan to operate there
- No more paying for duplicate licenses in every city and county you want to serve
This means that if you get licensed in Denver, you can operate your food truck anywhere in Colorado with just a 14-day notice — from Colorado Springs to Fort Collins to Boulder. It significantly reduces the cost and paperwork of expanding your food truck business across the state.
Step-by-Step: How to Get Your Denver Food Truck Licensed
- Secure your commissary kitchen agreement — Find and sign a contract with a licensed commissary facility in the Denver area.
- Get your food truck built or inspected — Ensure your truck meets all equipment requirements (hood suppression, sinks, refrigeration, propane system). If you’re building new, work with a manufacturer who understands Denver’s specific requirements.
- Submit your Mobile Plan Review — File your application with Denver’s Department of Excise and Licenses. Include your floor plan, equipment list, menu, commissary agreement, and proof of insurance.
- Schedule your fire inspection — Contact the Denver Fire Department to schedule your fire safety inspection. Have your hood suppression system professionally inspected by a third party first.
- Pass your health inspection — DDPHE will inspect your unit for food safety compliance.
- Obtain your Food Handler certifications — Ensure all employees have their Food Handler’s License and at least one team member has a Food Safety Manager Certification.
- Register for Colorado Sales Tax — Complete your free registration through the Department of Revenue.
- Receive your license and start operating — Once all inspections are passed and fees are paid, you’ll receive your Retail Food Establishment-Mobile license.
Common Reasons Food Trucks Fail Denver Inspections
Based on common inspection failures across Denver and Colorado, here are the issues that most frequently cause food trucks to fail their first inspection:
- Missing or improperly installed hood suppression system — This must be installed and third-party inspected before DFD will even look at your truck.
- Propane shutoff valve signage missing or incorrect — Must be 2-inch red letters on white background.
- No dedicated handwashing sink — A shared sink does not count. You need a separate, dedicated handwashing station.
- Inadequate hot/cold holding temperatures — Your equipment must reliably maintain food at safe temperatures.
- Missing commissary agreement — You cannot pass without a signed agreement from a licensed facility.
- Improper gray water disposal — You must have a contained system; dumping on the ground is an automatic fail.
