State License
STATE IDPH Plumbing LicenseRequired for all
Plumbing contracting in Chicago is a highly regulated trade requiring both state-level licensure and city-level registration. The Illinois Department of Public Health oversees the professional plumbing license, while the Chicago Department of Buildings manages local registration, permit issuance, and site inspections to ensure compliance with the Chicago Building Code.
Contractors must ensure all plumbing work is permitted before commencement. Failure to hold the proper credentials or perform work without a permit can result in stop-work orders, fines, and potential revocation of licensure. Always verify current requirements through the official City of Chicago and IDPH portals before beginning any project.
