You may just have a souvenir! In order to give you an exact answer I would have to know where you live. In general you will have to go to the building department in the municipality where you live. Example: unincorporated areas go to your town i.e. Town of Hempstead or North Hempstead or Oyster Bay. If you live in an incorporated village go to your village hall. Ask for for the file on your property. It has the entire history for work done on your home. If you have an open permit you will have to start with a new one and close that out. But you probably just have an old copy that was left behind.
If you want , you could probably just go there with your paperwork and ask someone to look at your file. They may have something on file that you do not.
