Full Breakdown

Per the Napa County Environmental Health Division page on Cottage Food Operations, 'State law was changed to allow private homes to be used for the preparation and packaging of some food products for sale to consumers under certain conditions' effective January 1, 2013 under California Assembly Bill 1616. There are two classes: Class A (direct-to-consumer sales only) requires registration with an annual fee and is inspected only on consumer complaint; Class B (sales direct to retail facilities and optionally to consumers) requires an Environmental Health permit with an annual fee and a mandatory annual routine inspection in addition to complaint inspections.

The 2024-and-beyond gross sales limit is $75,000 for Class A and $150,000 for Class B. Permitted products are limited to non-potentially hazardous baked goods such as cakes (without cream), cookies, bread, scones, candies, nuts, granola, and other items on the California Department of Public Health approved list. Both classes must submit product labels and a Food Handler Certificate within three months of registration or permit approval.

Violations & Fines

Operating a cottage food business without the required CFO registration (Class A) or permit (Class B), exceeding the annual gross-sales cap, selling non-approved food categories, or operating a home kitchen serving potentially hazardous foods (since Napa County has not opted into MEHKO) is a violation of the California Health and Safety Code and the County Environmental Health permit program. Penalties may include permit suspension, embargo of product, civil penalties, and referral for misdemeanor prosecution under HSC 113700 et seq.

Frequently Asked Questions

What can I sell from my home kitchen in Napa County?
Only non-potentially hazardous foods on the California Department of Public Health approved cottage-food list: items like cookies, breads, scones, dry candies, nuts, and granola. Items containing cream, meat, dairy custards, or other temperature-sensitive ingredients are not allowed because Napa County has not opted into the MEHKO program.
Do I need a permit or just a registration?
If you sell only direct to consumers (farmers market, your home, online), you need a Class A registration through Napa County Environmental Health. If you also sell wholesale to retailers, you need a Class B permit, which includes an annual routine inspection of the home kitchen.
Does my Cottage Food Operation also need a Home Occupation Permit?
Generally yes. The Cottage Food rules are a state Health & Safety Code program administered by Environmental Health, but the zoning rule in NCC 18.104.090 still requires an administrative home occupation permit before any home-based business can operate in the unincorporated county.
