Microenterprise Home Kitchen Operation (MEHKO) FAQs
This FAQ is converted from PDF to a Web page for your convenience. The original San Diego County FAQ PDF can be found here

General Info

1. What does the new law do?
The new law establishes a “microenterprise home kitchen operation”, also referred to as MEHKO, as a new type of retail food facility to be operated by a resident in a private home. The law requires a County to either allow or not allow MEHKOs in their jurisdiction, and the San Diego County Board of Supervisors has authorized a two-year temporary pilot program allowing MEHKOs to operate countywide. The Department of Environmental Health and Quality, Food and Housing Division (DEHQ-FHD) is the local enforcement agency responsible for issuing operating permits to MEHKOs pursuant to California Retail Food Code (CRFC) requirements and ensuring operational compliance.
2. When does the new law go into effect?
The new law was effective January 1, 2019. However, the new law gives the county “full discretion” to authorize the MEHKOs in their jurisdiction. With the recent authorization of MEHKOs within San Diego County, MEHKO operators will be able to submit their application packets to DEHQ-FHD starting on February 25, 2022.
3. What is a Microenterprise Home Kitchen Operation or MEHKO?
A MEHKO is a type of food service, like a mini restaurant, that is operated by a resident in a private home where food is stored, handled, and prepared that may be served to customers. Food must be prepared the day of service and can be eaten onsite or be delivered to the customer by the operator. Food may also be sold through an internet website or a phone-based mobile app belonging to an Internet Food Service Intermediary, but delivery must be by the MEHKOs operator or an employee of the MEHKOs facility. Food products may not be sold to a wholesale or retail facility. Third party delivery apps such as UberEats, Postmates, or GrubHub, etc., cannot be used by a MEHKO unless as provided for in CRFC Section 114367.5. A MEHKO does not include either of the following:
  • A catering operation, as defined in CRFC Section 113739.1.
  • A cottage food operation, as defined in CRFC Section 113758.
4. Who is the “local enforcement agency” for MEHKOs in the San Diego region?
The local enforcement agency for retail food facilities, including MEHKOs, in the San Diego region is the County of San Diego Department of Environmental Health and Quality (DEHQ).
5. What is meant by “private home”?
“Private home” means a dwelling, including an apartment or other leased space, where individuals reside. The MEHKO must be conducted within the primary residence. A MEHKO owner cannot have more than one primary residence, and second homes, vacation homes, or motor homes DO NOT qualify as a MEHKO.
6. If a person is renting a private residence/apartment or lives in a Homeowner’s Association (HOA), can they still operate a MEHKO?
A person must check their lease agreement to see if there are any restrictions to operating a home-based business out of the residence/apartment. If you have an HOA, it is advised that you make sure that a MEHKO is allowed by your HOA before applying for a MEHKO health permit.
7. What is the difference between a MEHKO and a Cottage Food Operation (CFO)?
A CFO is restricted to preparing and selling only prepackaged, properly labeled, non-potentially hazardous foods that have been approved by the California Department of Public Health (CDPH) (Approved Cottage Foods List), which may be sold directly or indirectly to the consumer. CFOs may not allow on-site food consumption. A MEHKO is able to prepare and serve potentially hazardous foods and are able to provide onsite dining, pick-up, or delivery options to their customers.
8. Can a person operate both a CFO and a MEHKO in their residence?
No, the law does not allow a CFO and a MEHKO in the same residence. The definition of a MEHKO does not include a CFO as provided for in CRFC Section 113825(b).
9. Can a person operate multiple CFOs or multiple MEHKOs in their residence?
No. A cottage food operator is an individual who operates a cottage food operation in his or her private home and is the owner (CRFC Section 113758). A MEHKO is a food facility that is operated by a resident in a private home where food is stored, handled and prepared (CRFC Section 113825). Both a CFO and MEHKO have limitations for the gross dollar amount allowed, number of employees, type of operation, allowed foods, etc. in a single residence. The law does not allow limits to be aggregated by multiple operations in the same residence.
10. Are multiple people living in the same residence allowed to each operate a CFO or MEHKO in that residence?
No. See Questions 8 and 9 above. There can only be one home kitchen operation (CFO or MEHKO) per residence.
11. What constitutes a meal?
While a meal is not defined in the California Retail Food Code, it should be sufficient in quantity to constitute a main course. This guideline is consistent with definition of a meal established by Alcohol Beverage Control (ABC) as part of their permitting process. Baked goods, condiments, sauces, or beverages are not considered a full meal.

Application Process

12. Is a permit required to operate a MEHKO?
Yes, a health permit is required from the County of San Diego Department of Environmental Health and Quality (DEHQ), Food and Housing Division, prior to operating.
13. How does a person who wants to operate a MEHKO obtain a permit from DEHQ?
In order to obtain a health permit, a person (the operator) must complete a permit application package that includes a health permit application, a “Standard Operating Procedures” form, the proposed menu, submit their Food Safety Manager Certificate, and a full panel of water testing results (if on a private well), and pay the permit fee. Once the application and procedures are reviewed and approved by DEHQ, an initial inspection will be scheduled and conducted at the private residence to verify compliance with state law. Once compliance is verified, the permit will be issued. Application packets can be picked up at the Department of Environmental Health and Quality Office, located at 5500 Overland Ave, Suite 170, San Diego, CA, 92123, or online at www.sdcdehq.org.
14. How long does the application process take for a MEHKO?
The application process is determined by the level of detail and completeness of the application package. The standard application process for MEHKOs is up to 20 calendar days if the application package is complete and the level of detail in the operational procedures is included to demonstrate compliance with the law. If the application must be sent back for revisions an additional 10 calendar days for review may be added.
15. Is approval from the FHD Plan Check Unit required prior to obtaining a MEHKO permit?
Plan check approval is not required prior to obtaining a MEHKO permit. However, if any remodel work is to be done at the residence to support the MEHKO, operators must contact their local Building Department to determine what, if any, approvals will be needed prior to starting construction.
16. What fees are associated with operating a MEHKO?
In order to operate a MEHKO, the initial health permit fee will need to be paid at the time of application, and then the operator will be responsible for paying their annual permit fee in each subsequent year. Additional fees will be applied for any justified complaint response as well as for reinspections that are needed to ensure compliance with the CRFC. For a list of current fees, please refer to the current fee schedule found at www.sdcdehq.org.
17. If an operator moves to a new residence, do they need to go through the application process again?
Yes, DEHQ permits are non-transferable. If an operator moves to a new residence, they must go through the application process again.
18. How does a customer determine if a MEHKO has an approved permit?
A MEHKO is required to display their permit, or a legible copy, during hours of operation. Customers can also visit www.SDFoodInfo.org to determine if a MEHKO has a valid permit.

Operational Requirements

19. Does a person need any special training or certification to operate a MEHKO?
The operator of the MEHKO must successfully pass an approved and accredited food safety manager course prior to submitting an application, and any individual, other than the operator, who is involved with the preparation, storage, or service of food in a MEHKO must also obtain a food handler card from one of the schools approved by DEHQ within 10 days of the start of their employment. Proof of food safety certification and foodhandler training must be available on site.

22. Are kids and pets allowed to be in a MEHKO?
Yes, the law exempts a MEHKO from certain requirements of the CRFC. However, MEHKO facilities are required to keep all children and animals outside of the kitchen and dining areas during food service and preparation.
23. Are there any meal or sales limitations for MEHKOs?
Yes, food preparation is limited to 30 meals per day or 60 individual meals per week and gross annual sales cannot exceed $50,000 as adjusted annually according to the California Consumer Price Index. Records of all sales must be kept so that compliance with this limitation can be verified. A meal log is recommended to ensure the maximum number of meals is not exceeded. The law also allows for DEHQ to limit the number of individual meals prepared if the physical space available for food preparation, food storage, and equipment storage is not adequate to support the number of meals being prepared.
24. Are there any restrictions to the type of food a MEHKO can serve?
