Frequently Asked Questions

A CFO is an enterprise at private home where specific low-risk food products, which do not require refrigeration, are prepared or repackaged for sale. A cottage food operator is an individual who operates a cottage food operation in his or her private home and is the owner of the cottage food operation. 

“Private home” means a dwelling, including an apartment or other leased space, where the CFO operator resides. 

Yes: A CFO can have one full-time equivalent employee (not counting family members). 

Yes: CFO sales are limited to no more than $75,000 for Class A and $150,000 for Class B of gross sales per calendar year.

Only foods that are defined as “non-potentially hazardous” are approved for preparation by CFOs. These are foods that do not require refrigeration to keep them safe from bacterial growth that may cause illness. The California Department of Public Health (CDPH) will establish and maintain a list of these approved foods and will establish a process by which new foods can be added to the list and other foods can be challenged and removed. Please contact the CDPH for more information regarding non-potentially hazardous foods.

 Class A: CFOs are only allowed to engage in “direct sale” of cottage food.

 Class B: CFOs may engage in both “direct sale” and “indirect sale” of cottage food.

“Direct sale” means a transaction within the state of California between a CFO operator and a consumer, where the consumer purchases the cottage food product directly from the CFO. Direct sales include, but are not limited to, transactions at holiday bazaars or other temporary events, such as bake sales or food swaps, transactions at permitted farm stands and certified farmers’ markets, through community-supported agriculture subscriptions, transactions occurring in person in the cottage food operation and transactions made via the phone, internet, or any other digital method. A direct sale may be fulfilled in person, via mail delivery, or using any other third-party delivery service. 

“Indirect sale” means an interaction within the state of California between a CFO, a third-party retailer, and a consumer, where the consumer purchases cottage food products made by the CFO from a third-party retailer that holds a valid permit issued by the local environmental health department in their jurisdiction. Indirect sales include, but are not limited to, sales made to retail shops or to retail food facilities where food may be immediately consumed on the premises. Please note, Class B CFOs wishing to sell their products indirectly through another third-party retailer located in another County may do so only when the other County agrees or gives approval.

Yes, you may deliver orders through the mail or by using a third-party delivery service directly to the customer within the state of California. 

 CFO operators are required to take a food handlers course offered by an ANSI accredited agency within 3 months of being registered or permitted. 

 All CFOs need to submit a self-certification checklist to verify that they comply with the operational requirements of a cottage food operation.

 Class A: CFO kitchens and food storage areas (referenced in the law as the “registered or permitted area”) are only inspected by the environmental health department when a consumer complaint alleging adulterated or unsafe food is being produced and is being investigated. Inspections for packaging, product handling and labeling may occur at community events. 

 Class B: CFO kitchens and food storage areas are inspected initially prior to permit issuance, and then annually thereafter, unless additional inspections are required in response to consumer complaints or concerns. Inspections for packaging, product handling and labeling may occur at community events.

In a permitted food facility, a cottage food product needs to be identified to the customer as homemade on the menu, menu board or other easily accessible location that would reasonably inform a consumer of its homemade status. Click here for more information regarding Cottage Food Labeling from the CDPH.

Any expansion or remodeling must be consistent with a residential home kitchen. Contact the Building/Planning Department(s) for approval & applicable permitting requirements. 

Cottage food operators or their employees shall not commit any act that may cause contamination or adulteration of food. This would include making foods that are not on the approved food list and or making foods under unsanitary conditions or with spoiled or rancid ingredients. A cottage food operation that is not in compliance with the requirements of AB 1616 would be subject to enforcement action taken by the local environmental health agency or the Department. 

You should notify your local environmental health agency or the Food and Drug Branch (FDB) immediately and do not distribute anymore product. You may need to notify your customers and request that they return or dispose of the products. You can contact FDB at: (916) 650-6500 or email: FDBinfo@cdph.ca.gov. 

You should check with your homeowner insurance company or your landlord if you are operating out of a rental property. Many homeowner insurance policies will not extend liability coverage to liabilities arising out of home-based businesses.

Please see the CDPH website or contact your local environmental health agency for guidance and resource documents or web links. 

Please contact the CDPH Food and Drug Branch for registration and facility requirements for food processors. Once the cottage food operation exceeds the gross sales volume established in the law, they must move their operations to a commercial processing facility and register with the California Department of Public Health under the Processed Food Registration Program. 

You can file a complaint at the Food and Drug Branch toll-free complaint line at 1-800-495-3232.
