Mobile Medical Units

Find out if your mobile medical unit needs a permit and inspection.

Does your vehicle qualify as a mobile medical unit?
Answer the following questions to find out:

  • Is the vehicle used for something other than emergency response?
  • Are medical examinations, treatments, medical or dental services or procedures provided in the vehicle?
  • Is the vehicle built on a chassis?
  • Is the vehicle designed for use at temporary locations?
  • Does the vehicle include electrical, plumbing, OR gas piping systems of some sort?

If the answer is “yes” to all of the questions above, then you have a mobile medical unit.

 

Submit plans for alternations or changes UNLESS you have an exempt mobile medical unit.

A unit is exempt if it has been used outside Washington state as a mobile medical unit for six months or more. Otherwise, all units must submit plans and be inspected.

To purchase a permit for a unit exempt from plan review, visit your local office to:

  • Complete the Food Truck/Trailers/Temporary Structures Application F623-037-000.
  • Pay the $113.80 inspection fee.
  • Get the Pre-inspection Checklist for Exempt Units F622-073-000.

Submit plans and have your unit inspected.

Here's the process for getting your mobile medical unit alteration plan approved and the work inspected and approved by L&I:

    • Expand/collapse First, you need to create a plan and submit it to L&I for review.

      The conversion vendor unit (or mobile medical unit) plans you submit for plan review must contain enough information to determine conformance with the applicable conversion vendor and medical unit codes.

      Structural: Only concentrated loads of 500 pounds or more in a 16-square-foot area need to be addressed. Compliance can be accomplished by means of WAC 296-150V-0350. This would apply to units that were either built or converted from another structure as a Vendor Unit" under WAC 296-150V. If you wish to build or convert a structure into a "Commercial Coach," please contact the Department at FactoryAssembldStruc@Lni.wa.gov or 360-902-5218.

      Electrical: Show the general location of outlets, lights, switches, and the main distribution panel box (this may be combined with the floor plan drawing or done as a separate drawing). Include a schedule showing what the breakers in the main panel box are, including breaker sizes and what they control. Provide electrical load calculations that show the overall electrical demand in amps. (See sample Electrical Floor Plan.)

      Plumbing (Water): Show the locations of all sinks, holding tanks, and other plumbing fixtures. Include pipe sizes for water supply. Provide information on the operating pressure in the water supply system as well as the length of water piping from the inlet or pump to the furthest fixture. (See sample Water plan.)

      Plumbing (Drain): Show the locations of all sinks, holding tanks, and other plumbing fixtures. Include pipe sizes for drainage, waste, and vent pipes. Show the location and size of the drainage system outlet. (See sample Drain plan.)

      Mechanical: If you have gas appliances in your commercial coach, you must show the gas piping layout and size. You will be required to supply the BTU/H input requirements for all gas appliances. Show the location of the gas supply inlet or tank. Provide the type of fuel (i.e.: natural gas or propane) and the length of the piping run from the tank or inlet to the furthest appliances. If you have a heating or air conditioning appliance, you will have to show conformance to the state energy code on the forms provided. (See sample Gas plan.)

      See all these printable Sample Plans.

    • Expand/collapse Next, L&I must review and approve your plan before you start the work.
    • Then, L&I must inspect and approve the work you've done.

      Go on to "Inspections" page.

 

Note: Be sure to check with all local building departments where you plan to use your unit. Some building departments may not allow the use of conversion vendor units in their jurisdiction. You may be required to have a commercial coach in that jurisdiction.
