You need to be aware of a few laws, including and especially zoning laws and health codes for food preparation in the home. You need to discuss the zoning issue with your attorney or building and safety department to see what you are currently zoned for and whether you would be allowed to conduct such a business (home based) with the zoning you currently have or if you must try and qualify for an exception or zone change for your particular area or home. The latter is usually impossible. With food preparation, the health inspectors and possibly other state and federal agencies will need to be aware of how you prepare, how you store the material and the like to ensure no spoilage is occurring and the food is fit for consumption.
