California Uses an Approved List Model
Unlike most states that simply prohibit certain foods, California takes the opposite approach: you may only sell foods that appear on the California Department of Public Health (CDPH) Approved Cottage Foods List. If a product isn't on that list, it isn't allowed — even if it's shelf-stable and low-risk. The CDPH updates the list periodically and sellers can petition to add new products. Always verify your specific product at cdph.ca.gov before you start selling.
Open, Restricted & Prohibited Foods
Every food category is classified into one of three tiers. Open means clearly allowed under the approved list. Restricted means allowed with specific conditions. Prohibited means not permitted under any cottage food registration — a commercial kitchen license is required instead.
Understanding California's Approved List System
California's restrictions aren't arbitrary — they're rooted in food science. The core concept is non-potentially hazardous food, or non-TCS food (food that requires no Temperature Control for Safety). Regulators classify foods as cottage-food-eligible based on two measurable properties:
The Approved List vs. a Prohibited List
Most states use an exclusion model: everything is allowed unless specifically prohibited. California flips this. Only products on the CDPH Approved Cottage Foods List are permitted — and the list is intentionally conservative. This means a product that's legal in Texas or Virginia under cottage food law may be prohibited in California, simply because it hasn't been formally added to the approved list.
The good news: the CDPH list can be expanded. If you make a product you believe is non-potentially hazardous but isn't on the list, you can submit a petition to [email protected]. CDPH reviews petitions and posts any changes 30 days before they take effect.
What Happens with Acidified Foods?
Pickles, hot sauce, salsa, and chutneys fall into a category called acidified foods — products where an acid (vinegar, citric acid, lemon juice) is added to lower pH to a "safe" level. While this sounds straightforward, improper acidification creates conditions for Clostridium botulinum, the bacterium behind botulism. California requires acidified food producers to use a licensed commercial kitchen, have their process validated by a Process Authority (a certified food scientist), and in many cases register with the FDA. These requirements exist regardless of sales volume or how experienced the seller is.
