In Illinois, plumbers must hold a state license issued by the Illinois Department of Financial and Professional Regulation (IDFPR). You can verify any plumber's license by visiting the IDFPR online portal at idfpr.illinois.gov. When you contact a plumber, ask to confirm their license status before scheduling work.

The City of Chicago requires permits for plumbing work. The Department of Buildings issues these permits to help ensure construction work meets code. Ask your plumber whether a permit is needed for your project—most installations and major repairs require one. The plumber should handle permit applications, or confirm who is responsible.

Before hiring, ask the plumber about their experience with your specific fixture or system type, their warranty coverage, and whether they can provide a written estimate. Request references if the job is substantial. Verify that they understand Chicago's local plumbing codes and building requirements.
