Call your local Health Department to check up on regulations. You will more than likely need to get a series of permits, insurance and inspection certificates.
Decide if you want to provide chef services (also known as in-home catering) or if you want to start a larger business, in which case you will need to rent an industrial kitchen.
Plan a menu, paying special attention to what type of food you plan to offer and what type of food is off limits. Dishes that require exotic ingredients or are complex may not be the best option at the beginning of your business.
Consider taking a few classes or workshops to learn about food trends and exotic meals before you start. Or invest in a business management class so you learn what's involved in managing your own business.
Contact the National Association of Catering Executives to learn more about the business, get ongoing support and connect with other professionals in the business (see Resources below).
