Hello,
My question is what requirements are there to open a home based bakery (cakes only) business in California?
What are the regulations? What licenses are required? What permits are required?
Anything else that is required to have and open a home bakery (cakes only) buiness in California?

Who are you going to be selling the cakes to.

Bakery
1. business license
2. kitchen inspected and approved by health department ( requires specific materials and sanitation)
3. labeling of cakes as required by law.
