Break up cement patio on Sat?

This may be a stupid question, but id rather ask then get fined. We are building a house in Bay Ridge. Im wondering if I can go there and break up a cement patio on a Saturday with a hammer. No power tools. Is it ok to make a little noise like this on the weekend? Or can I get a fine for doing some sort of “unpermited weekend work”?
