Do I need a permit for plumbing fixture or repiping in Joliet?
Yes. In Illinois, plumbing fixture or repiping generally requires a permit, and Joliet is no exception.
Repiping a home's water distribution or drainage requires a permit in most Illinois jurisdictions and must be performed by an Illinois-licensed plumber under the statewide Illinois Plumbing Code. Minor repairs such as clearing a stoppage or replacing a faucet are typically exempt, but replacing or rerouting piping is not. Re-piping water, waste, or vent lines is a plumbing system change reviewed under the Illinois State Plumbing Code, and Joliet requires a plumbing permit for this work. Plumbing is a licensed trade, so a registered plumbing contractor generally must pull the permit (Sec. 8-36 of the Code of Ordinances) and carry a Certificate of Insurance naming the City of Joliet as certificate holder. Apply by emailing the Plumbing permit application to permitapplication@joliet.gov or using the City Hall drop box. There is no online permit portal, and incomplete submittals are returned to the applicant.
