Lulabell, this is one of those situations where you're really going to need to contact local authorities about your plan. I suspect that you'll need to be licensed for manufacturing, and your rented premises will probably need to pass a health and safety inspection since you're making and handling food. You should probably start working through California Department of Food and Agriculture (
http://www.cdfa.ca.gov). Also, contact some place like the Pacific Coast Farmers Market Association (
http://www.pcfma.com) to see their requirements for food producers; on their site they have a section called:
Resources for Non-agricultural Producers
PCFMA's markets also include specialty food items such as breads, pastries, jams, seafood, and gourmet sausages. Some markets also include ready-to-eat foods such as various ethnic specialties or rotisserie-cooked chicken. These items provide additional choices for consumers and support local entrepreneurs.
In certain markets, PCFMA is restricted by its contract with the market sponsor concerning the number or type of non-agricultural products that can be sold in that market. All non-agricultural products must be juried by PCFMA before they are admitted to a market.
All non-agricultural producers must have a health permit covering the kitchen at which their products are produced and packaged (products cannot be made in home kitchens) as well as health permit from the county in which they wish to sell their products.
PCFMA invites specialty food producers offering items other than certified California agriculture to download, complete and return the Non-Agricultural Producers Application to Sell. These producers must pay an application fee and provide copies of certain documents including health permits for the point of production, proof of product liability insurance and proof of auto insurance. A full list of required documents is included with the Application to sell.
