In PA you need to go through the dept of agriculture. They have all of the info that you could wish for regarding mobile food facilities and the like. Register your business with the state, including all of that hoopla about the fictitious name registry. After you are open for business I believe you have 90 days to become serve safe certified or hire someone who is. If you are going to do only small catered events, get your certification, about a million in G.L insurance and start small. After you have a few jobs under your belt, slowly take on bigger jobs. One question, what kind of store does your dad have. If he sells food already, you don't have any kind of issue, you'll just need to be inspected as part of his business license. Don't hesitate to ask questions,I'll be more that happy to help any way that I can.
