Please remember to pull permits on all plumbing jobs in Chicago. There is no exception. Also all jobs must be inspected by a City of Chicago Plumbing Inspector. If you have any questions call City of Chicago 311 help line. Also insist on an Union Licensed Plumber. Call Plumber’s Local 130 to get the training you need to be a professional. Also feel free to E-Mail me with any questions on Plumbing License Law in Chicago or Illinois. Photo by Brigid McDonough.
