Microenterprise Home Kitchen Operations (MEHKO)


As of January 1, 2019, AB 626, known as the Microenterprise Home Kitchen Operations Act, became law. The law authorizes San Mateo County to permit home kitchens for retail use.  

A Microenterprise Home Kitchen Operation (MEHKO) is a food facility that is operated by a resident from their private home kitchen. Once permitted, a resident can store, handle, prepare, and serve food to the public as allowed by State law like a restaurant. State law does place limits on the number of meals that can be served, revenue that can be received, and on some foods that can be prepared among other requirements.  

San Mateo County is conducting a two-year pilot program for these types of facilities.
