What license do I need to work as a commercial plumber in Chicago?

Requirements depend on the jurisdiction, your classification and the scope of the assignment. Check the official Illinois Department of Public Health — Plumbing for current license types, exams and renewals, and confirm any city or county requirements. Each posting states its own credential requirements.

  • Illinois Department of Public Health — Plumbing

Do I need medical gas or backflow certification?

Only when the assignment includes that scope. Medical gas and backflow testing credentials are jurisdiction- and assignment-specific; the posting or your recruiter will confirm whether they apply.

How do union rules work for plumbers in Chicago?

Membership, apprenticeship, dues and referral rules are set by each local and its agreements, not by Gulfstream. Contact the hall directly for current rules. Gulfstream recruits for both union and merit-shop contractors and is independent of every union; our recruiting is separate from hall dispatch.
