TranslateCottage Food Operation Permit Requirements for Operators on Septic Systems
This guidance document is for Cottage Food Operations that are connected to an onsite septic system for liquid waste disposal, verses a county or city sewer system.
Cottage Food Operation (CFO) is governed under the California Homemade Food Act and it allows for certain types of food to be prepared and sold from a home kitchen operated food facility. Governor Brown signed the California Homemade Food Act into law on September 21, 2012.
A cottage food operation may increase the volume and/or strength of the waste water depending on the type of business operation. Residential septic systems are designed for the wastewater flow typically associated with normal day to day use of the occupants, such as laundry, kitchen use and bathing.
Depending on the type of the cottage food operation, some can have high uses of sugar, fats, oils or grease that may be washed down the drain as a result from cooking, baking or cleaning associated with operation. The higher waste strength and increased water use can cause the septic system to perform poorly or fail, which can then lead to needing a repair or replacement septic system that can be costly.
It is important to maintain your septic system and have the septic tank inspected and pumped on a recommended 3-5 year interval or regular basis based on use.
For both Class A and B Cottage Food Operation Permits, applications can be obtained through Environmental Heath. Environmental Health will review and approve the application.

Graywater Not Allowed
Graywater systems cannot be utilized for cottage food operations. Food processing wastewater, like wastewater from kitchen sinks, is considered “black” water and cannot be routed to a graywater dispersal system.
The California Plumbing Code Chapter 16A excludes wastewater from kitchens from the definition of graywater. Graywater is defined as “untreated wastewater that has not been contaminated by any toilet discharge. Graywater includes wastewater from bathtubs, showers, bathroom sinks, clothes washing machines and laundry sinks. It does not include wastewater from kitchen sinks, dishwashers, photo lab sinks or laundry water from soiled diapers.”
General Recommendations
- Minimize the amount sugars, fats, oils, or grease entering your septic system by scraping and wiping utensils and surfaces prior to washing and avoid washing food scraps down the drain.
- Have your septic tank pumped at the recommended frequency, once every 3-5 years or on frequency based on use.
- If you have a nonstandard system under an operational permit with our office, you should have your system maintained according to the requirements in the terms and conditions of your septic operational permit.
