I'm not sure about age restrictions, but I know that performing/busking does not require a permit unless you are selling a product, or if your show would require performers insurance. I know one magician who would come out with one or both of his parents. He was only 12 and performed on Pearl Street legally.
I am almost positive if your under 18, your parent's or gaurdian must give permission, just check at the court house to b sure
Yeah I'm not sure either but i honestly don't think you will have any problems!! I s as y go for it and enjoy and prosper.
Good luck
I am almost sure that you will have to fight for your turf
