Kitchen Trailer Inspection Checklist Requirements in Oregon

Did you know Oregon overhauled its mobile food unit regulations in 2020, setting tougher standards for kitchen trailer design, safety, and inspections? If you plan to operate a mobile kitchen in Oregon, passing these inspections isn’t optional, it’s the only way to open legally and avoid costly delays.

To get licensed, every kitchen trailer must clear two critical steps: a DMV safety inspection and a food safety inspection by the Oregon Health Authority (OHA). Many operators underestimate this process, but failing an inspection can result in penalties, lost time, or even a shutdown.

Oregon also happens to be home to one of the most vibrant mobile food scenes in the U.S. In Portland alone, more than 500 food carts and trailers thrive in designated “pods.” From coastal seafood kitchens to Willamette Valley winery catering trailers, the opportunities are endless but only if your trailer meets Oregon’s strict inspection requirements.

This article breaks down a complete kitchen trailer inspection checklist for Oregon, including DMV standards, OHA food safety rules, fire code compliance, and practical tips to help you stay compliant from day one.

Why Oregon Enforces Food Safety Rules

Oregon has one of the most vibrant street food cultures in the U.S., especially in Portland, where hundreds of food trailers operate daily. With this popularity comes high responsibility: the state enforces strict rules to minimize risks of foodborne illness, fire hazards, and sanitation problems in confined mobile kitchens.

By complying with these standards, kitchen trailer operators not only avoid penalties and shutdowns but also gain credibility in a competitive food scene.

Agencies Involved in Kitchen Trailer Permits & Licenses

• Oregon Health Authority (OHA)

Oversees statewide food safety rules under the Oregon Food Sanitation Rules. The OHA’s Food Safety Division collaborates with counties to review plans, issue licenses, and conduct inspections.

• County Health Departments

Issue mobile food unit licenses within their jurisdictions. Requirements can vary: for example, Multnomah, Lane, Marion, and Deschutes counties may apply additional inspection criteria.

• Oregon DMV

Regulates mechanical safety, licensing, and registration of kitchen trailers. Passing a DMV inspection is mandatory before operation.

• Local Fire Marshals

Enforce fire safety codes, propane storage rules, and suppression system compliance. Fire marshal approval is often required before final licensing.

Passing inspections in Oregon requires kitchen trailers to meet structural, sanitation, equipment, utility, fire, and DMV safety standards. Below is a practical checklist operators can use to prepare for both OHA health inspections and DMV safety reviews.

1. Structural & Sanitation Standards

• Floors, walls, ceilings: Smooth, durable, and non-absorbent surfaces required (OAR 333-150, Food Sanitation Rules).
• Handwashing sink: Required, separate from the three-compartment sink; must provide soap, towels, and signage (OAR 333-162).
• Water supply: Potable water with hot (≥100 °F) and cold running taps.
• Wastewater tank: At least 15% larger than freshwater capacity (OHA guideline).
• Lighting & ventilation: Adequate brightness with protected fixtures; vents must prevent grease buildup.

2. Food Trailer Equipment Compliance

• NSF-certified appliances: All cooking and refrigeration equipment must meet NSF standards.
• Temperature controls:
  • Cold storage ≤ 41 °F
  • Hot holding ≥ 135 °F (FDA Food Code standard, adopted by Oregon).
• Ventilation hoods & fire suppression: UL-300 compliant hood system required over fryers/grills producing grease.
• Food prep surfaces: Non-toxic, smooth, and easily cleanable.

3. Utility Systems & Safety

• Plumbing: Proper backflow prevention, indirect drains/air gaps, and grease trap where required.
• Electrical: NEC-compliant wiring; no exposed conductors or makeshift connections.
• Propane/gas lines: Cylinders secured; lines must be leak-free with accessible shutoff valves.
• Waste disposal: Proof of commissary or service agreement for disposal of graywater and FOG (fats, oils, grease).

4. Fire & Safety Codes

• Class K extinguisher: Mandatory for fryers or grease-producing appliances (Oregon Fire Code, OSFM guidance).
• Hood suppression system: Must be serviced and documented on schedule.
• Emergency exits: Clearly marked and unobstructed.
• Propane storage: Cylinders mounted securely; local fire marshal enforces capacity limits.
• CO detectors: Recommended in enclosed propane/generator units.

5. Mechanical & DMV Safety Inspection (Trailer Chassis & Roadworthiness)

Before foodservice review, trailers must pass an annual Oregon DMV vehicle inspection (Oregon DMV).

• Chassis, frame & hitch: Free of rust, cracks, or weld failures.
• Brakes, axles & suspension: Fully functional.
• Wheels & tires: Legal tread depth, correct inflation, intact bearings.
• Lights & reflectors: Brake lights, signals, and reflectors operational.
• Couplers & safety chains: Dual chains and breakaway system (if required).

Tip: Oregon inspectors may request to review operational logs (temperature records, cleaning schedules, fire suppression service logs). Having these organized improves your chance of passing on the first inspection.

1. Food Trailer Permit & Health Inspection

Every mobile kitchen trailer must hold a valid mobile food unit license issued by the county health department. Licensing is based on the Oregon Food Sanitation Rules (OAR 333-150), which adopt the FDA Food Code.

• Applications typically require floor plans, menu, and commissary agreement.
• Trailers must pass an OHA food safety inspection, covering sanitation, water supply, equipment, and structural standards.
• Local environmental health inspectors conduct both plan review and on-site inspection before a license is issued.

2. Insurance & Liability Coverage

Operators must carry:

• General liability insurance – protects against foodborne illness and injury claims.
• Commercial auto/trailer policy – required for DMV registration and legal road use.
• Property/equipment coverage – insures cooking appliances, generators, and interior fit-out.

3. Fire Department Inspection

Any trailer with cooking appliances must pass a fire safety review by the local fire marshal. Requirements include:

• UL-300 fire suppression system over fryers and grills.
• Commercial hood with grease filters, serviced regularly.
• Tagged Class K extinguisher.
• Propane shutoff valves and cylinder storage compliant with the Oregon Fire Code.

4. DMV Registration & Road Compliance

Trailers must be registered with the Oregon DMV as commercial vehicles (Oregon DMV). Requirements include:

• VIN/title verification.
• Functional brakes, axles, and lighting.
• Proper safety chains and hitch.
• Compliance with trailer weight class and inspection standards.

5. Zoning & Location Permits

Local zoning laws control where trailers may operate:

• In Portland, trailers often operate in designated “pods” with site utility requirements.
• Counties may set additional rules for trash storage, wastewater disposal, and generator use.
• Operators must confirm location compliance before siting their trailer.

6. Temporary & Event Permits

Special permits are required for short-term operations at farmers markets, fairs, or festivals. Counties typically issue a temporary restaurant license, which bundles food safety, fire, and location requirements into a single approval.

7. Waste Management & Environmental Compliance

Operators must demonstrate safe disposal of wastewater and grease:

• Licensed waste haulers required for graywater and FOG (fats, oils, grease).
• Most counties require a commissary agreement showing where fresh water is obtained and waste is disposed.
