Plan Check & Operational Guidelines for Mobile Food Facilities and Mobile Support Unit

Overview

These guidelines have been established to assist in the permitting process for a mobile food facility. The following requirements are extracted from the California Health & Safety Code, California Retail Food Code (Cal Code) .

A Mobile Food Facility is any vehicle used in conjunction with a commissary or other permanent food facility upon which food is sold or distributed at retail. A Mobile Food Facility does not include a transporter used to transport packaged food from a food facility, or other approved source to the consumer. The Mobile Food Facility shall be designed as a self-contained unit. The cart design shall take into consideration local environmental conditions for a safe food operation and storage of the Mobile food Facility.

A Mobile Support Unit is a vehicle, used in conjunction with a commissary that travels to, and services, mobile food facilities as needed to replenish supplies, including food and potable water, clean the interior of the unit, or dispose of liquid or solid wastes. Mobile Food Facilities that are serviced by an MSU and that do not intend to go back to the commissary shall submit an alternate storage location for Department approval.

Permits

All vehicles shall have a valid Los Angeles County Public Health Permit in order to operate legally in Los Angeles County. The permit shall note the specific vehicle license plate number and the name of the current registered specific vehicle license plate number and the name of the current registered owner of the mobile food facility. A valid DMV registration, if applicable, and a valid identification for each owner are required to obtain a public health permit. If the owner is a Corporation, Limited Liability Company, or a Limited Partnership, either domestic or foreign, a current copy of the corporate documents, including but not limited to: Statement of Domestic Stock Corporation and Articles of Incorporation, must be submitted to the Department. The health permit shall be posted or otherwise maintained within the vehicle at all times.

Commissary

All mobile food facilities shall operate out of a commissary, mobile support unit, or other approved Facility. A commissary is a food facility that services mobile food facilities, and mobile support units where food, containers, or supplies are stored; food is prepared or prepackaged for sale or service at other locations; utensils are cleaned; liquid and solid wastes are disposed of; and potable water is obtained. See Commissary list for Mobile Food Facilities. A restaurant or market may also act as a commissary when approved by this agency. STORAGE OF THE MOBILE FOOD FACILITY OR ANY TYPE OF FOOD PRODUCT AT HOME IS NOT APPROVED.

Owners of mobile food facilities shall provide a written statement signed by the commissary owner stating that the cart will be stored and serviced at that location. A copy of the Verification of Proper Food Vehicle Storage is included in this document. This Department conducts random inspections for verification of commissary use. A permit shall not be issued until the commissary location is verified and approved by this Department.

Minimum Standards of Knowledge in Food Safety

All food employees shall have adequate knowledge of, and shall be properly trained in, food safety as it relates to their assigned duties. Food facilities that prepare, handle, or serve non-prepackaged potentially hazardous food, shall have an owner or employee who has successfully passed an approved and accredited food safety certification examination. The certification is valid for five years from the issue date. There shall be at least one food safety certified owner or employee at each food facility. No certified person at a food facility may serve at any other food facility as the person required to be certified. A food facility that commences operation, changes ownership, or no longer has a certified owner or employee pursuant to this section shall have 60 days to comply.

Written Operational Procedures

The permit holder of a mobile food facility handling nonprepackaged food shall develop and follow written operational procedures for food handling and the cleaning and sanitizing of food contact surfaces and utensils. The enforcement agency shall review and approve the procedures prior to implementation and an approved copy shall be kept on the mobile food facility during periods of operation. See Written Operational Procedures.

Business Permits

Owners shall obtain the necessary business permits from the local City Hall or County Business License office prior to operating. Local cities may have restrictions regarding food sales from vehicles. All vehicles are to display a current Public Health Permit and a current certification decal.

Identification

The business name or name of the operator, city, state, zip code, and the name of the permittee, if different from the name of the food facility, shall be legible, clearly visible to patrons, and permanently affixed on the customer side of the mobile food facility and mobile support unit. The name shall be in letters at least 3 inches high and shall be of a color contrasting with the vehicle exterior. Letters and numbers for the city, state, and zip code shall not be less than 1 inch high.

Motorized mobile food facilities and mobile support units shall have the required identification on two sides.

Equipment

Manufacturer's specification sheets are required for all proposed equipment. All equipment on mobile food facilities shall be certified or classified for sanitation by an American National Standard Institute (ANSI) accredited certification program. In the absence of an applicable ANSI certified sanitation standard, food-related and utensil-related equipment shall be evaluated for approval by the enforcement agency.

All new and replacement gas-fired appliances shall meet applicable ANSI standards. All new and replacement electrical appliances shall meet applicable Underwriters Laboratory standards. The installation of gas-fired equipment shall be UL approved.

All gas-fired appliances shall be properly insulated in a manner that will prevent excessive heat buildup and injury.

HCD Insignia

Each enclosed mobile food facility may be required to be certified by the Department of Housing and Community Development.

Toilet Facilities

Mobile food facilities shall be operated within 200 feet travel distance of approved and readily available toilet and hand washing facilities or as otherwise approved by the enforcement agency, to ensure restroom facilities are available to facility employees whenever the mobile food facility is stopped to conduct business for more than a one hour period.
