What Is a Mobile Food Facility (MFF)?
A Mobile Food Facility (MFF) is any vehicle or unit used to sell food to the public—this includes:
- Food trucks
- Food trailers
- Push carts (hot dog carts, coffee carts)
- Ice cream trucks
- Specialty mobile units
California law defines an MFF as a vehicle operating in conjunction with a commissary or approved facility.
The Law That Governs MFFs
All MFFs fall under the California Retail Food Code (CalCode), which regulates:
- Food safety
- Equipment requirements
- Sanitation
- Permitting
Local county health departments enforce these rules statewide.
1. You MUST Have a Health Permit (No Exceptions)
Before selling any food:
- You need a health permit from your county
- Each vehicle requires its own permit
- You must pass inspection before operating
Operating without a permit can result in fines or shutdowns.
👉 Important:
Your permit is NOT transferable between counties—you must apply separately in each county you operate.
2. Commissary Requirement (Biggest Rule Most People Miss)
Every MFF must operate out of a commissary kitchen.
What is a commissary?
A licensed commercial kitchen used for:
- Food prep and storage
- Cleaning equipment
- Dumping wastewater
- Refilling water
Key Rules:
- Must report to commissary daily (in most cases)
- Must store food and supplies there
- Must clean and service unit daily
California law explicitly requires MFFs to operate in conjunction with a commissary unless exempt.
👉 This is one of the #1 reasons applications get denied.
3. Types of Mobile Food Facilities (Critical for Compliance)
Your rules depend on your MFF type:
Enclosed MFF (Food Trucks / Full Trailers)
- Full cooking allowed
- Requires full equipment (hood, sinks, refrigeration)
- Considered “high-risk” if cooking raw food
Unenclosed MFF (Carts)
- Limited food prep only
- Examples: hot dog carts, coffee carts
- Restricted menus
California distinguishes these based on food preparation level.
4. Food Safety & Equipment Requirements
Depending on your menu, your MFF must include:
Required Equipment:
- Handwashing sink
- Warewashing sink (for dishes)
- Refrigeration (if handling perishable food)
- Hot water system
- Food-grade surfaces
If handling “potentially hazardous foods” (meat, dairy, etc.), stricter requirements apply.
5. Daily Operations Rules
California requires strict daily procedures:
- Must be cleaned and serviced every day
- Must return to commissary (unless approved otherwise)
- Must store food properly after operations
Failure to follow these rules can lead to permit suspension.
6. Location & Operating Restrictions
You must:
- Be within 200 feet of a restroom (for staff)
- Operate only in approved zones
- Follow city-specific parking laws
You cannot:
- Set up extra tables outside your unit (in most cases)
- Operate open-air cooking separately
- Ignore route reporting requirements
Many counties require submitting your daily route schedule.
7. Plan Check (Before You Build or Buy)
Before launching:
- Submit detailed plans (layout, plumbing, equipment)
- Get approval from the health department
- Wait for inspection approval
Plan reviews can take 2–4 weeks or longer.
👉 If you skip this step, you risk building a trailer that can’t be permitted.
8. Certifications & Staffing Requirements
Most MFFs require:
- Food Protection Manager Certification (within 60 days)
- Food handler training for staff
This ensures safe food handling practices.
9. Additional Compliance Rules
You’ll also need:
- Business license
- Seller’s permit
- DMV registration (for trucks/trailers)
- Commissary agreement
- Route schedule
These are required during permit application.
10. Inspections & Ongoing Compliance
Once operating:
- Annual permit renewal required
- Regular health inspections
- Must maintain sanitation standards
Health departments treat MFFs the same as restaurants for safety compliance.
Biggest Mistakes That Kill Food Trailer Launches
Most people fail compliance because they:
- ❌ Buy a trailer before plan approval
- ❌ Don’t secure a commissary
- ❌ Choose equipment that doesn’t meet code
- ❌ Underestimate local city restrictions
- ❌ Try to operate in multiple counties without permits
Pro Tip (From a Financing Perspective)
If you’re financing a food trailer:
- Lenders look for permit-ready builds
- Non-compliant trailers = harder approvals
- Commissary agreements strengthen your application
👉 This is why aligning your build with MFF rules early is critical.
Final Takeaway
California MFF rules are strict—but they follow a clear structure:
- Get your design approved
- Secure a commissary
- Build to code
- Obtain permits
- Pass inspection
- Operate with daily compliance
If you follow this process correctly, you can go from concept → fully operational food trailer without delays or rework.
