Licensing Requirements
Illinois does not issue a single statewide plumbing license — licensing is administered at the local level through the Illinois Plumbing Code and enforced by municipalities. In Aurora and Kane/DuPage County, plumbers must hold a City of Aurora Plumber's License or a recognized equivalent. The standard path requires passing the Illinois Plumbing Contractors Licensing Exam (administered by the Illinois Department of Public Health, IDPH) or a recognized local exam. Journey-level plumbers must complete a state-approved apprenticeship (typically 5 years / 10,000 hours) and pass a journeyman exam. Master Plumbers must hold journeyman status, accumulate additional experience (typically 2+ years at journeyman level), and pass a Master Plumber exam. Contractors operating a business must hold a Plumbing Contractor license issued by the local authority. Licenses renew annually or biennially depending on the issuing municipality. Continuing education requirements vary by jurisdiction — Aurora requires staying current with Illinois State Plumbing Code updates. Verify current exam and renewal requirements directly with the City of Aurora Building Division and IDPH.
Permit Requirements
Any plumbing work beyond simple fixture repair requires a permit from the City of Aurora Building and Permits Division. This includes new installations, water heater replacements, sump pump installations, water/sewer line work, and any rough-in for additions or remodels. Permit fees are calculated based on project valuation. Applications are submitted to the Aurora Building Division at 44 E. Downer Place. Permit turnaround is typically 3–7 business days for standard residential work. Contractors must be licensed with the City before permits are issued in their name.
Inspection Schedule
Aurora requires inspections at rough-in stage (before walls are closed) and a final inspection upon project completion. Water and sewer lateral work may require a separate inspection by Aurora's Public Works department before backfill. Water heater replacements typically require a final inspection only. Inspection scheduling is handled through the Aurora Building Division — allow 24–72 hours for scheduling. Failed inspections require corrections and re-inspection, which adds time and cost, so get the rough-in right the first time.
Insurance Minimums
Illinois does not mandate a single statewide insurance floor for plumbing contractors, but the City of Aurora and most general contractors require proof of General Liability Insurance with a minimum of $1,000,000 per occurrence / $2,000,000 aggregate. Workers' Compensation Insurance is required by Illinois law for any contractor with employees — no exemption for small crews. Many commercial GCs and property managers in the Aurora market require $2,000,000 per occurrence. Umbrella policies of $1,000,000–$5,000,000 are common on larger commercial bids. Certificates of insurance must name the City of Aurora as additional insured for permitted work.

How to Get Licensed
Complete an Approved Apprenticeship
Enroll in and complete an Illinois-approved plumbing apprenticeship program, typically run through a Joint Apprenticeship Training Committee (JATC) affiliated with UA Local unions or a state-approved non-union program. The standard apprenticeship is 5 years / approximately 10,000 hours of on-the-job training combined with related technical instruction. Aurora-area apprentices commonly affiliate with Plumbers Local 130 (Chicago) or Local 99 (Joliet/Fox Valley area). Verify program approval with the Illinois Department of Labor.
Pass the Journeyman Plumber Exam
Upon completing your apprenticeship, pass a journeyman plumber examination recognized by the Illinois Department of Public Health (IDPH) and the City of Aurora. Exams typically cover the Illinois State Plumbing Code, pipe sizing, fixture installation, backflow prevention, and safety standards. Aurora may accept exams administered by recognized testing bodies — confirm accepted exams with Aurora's Building Division before scheduling.
Apply for Journeyman License with City of Aurora
Submit a journeyman plumber license application to the City of Aurora Building and Permits Division at 44 E. Downer Place, Aurora, IL 60505. Required documentation typically includes proof of apprenticeship completion, exam results, valid government-issued ID, and applicable licensing fees.

Accumulate Master Plumber Experience
After obtaining journeyman status, work as a licensed journeyman plumber for the required period — typically 2 or more years — to qualify for the Master Plumber exam. Document your work history carefully, as you will need to verify this experience when applying for master-level licensure.
Pass the Master Plumber Exam
Pass a Master Plumber examination recognized by the City of Aurora and IDPH. The master exam covers advanced plumbing code requirements, system design, contractor responsibilities, and project management. Study current editions of the Illinois Plumbing Code. Some contractors also prepare using ICC study materials. Confirm accepted exams with Aurora's Building Division.
Obtain Master Plumber and Contractor License
Apply for your Master Plumber license with the City of Aurora, providing proof of journeyman experience, master exam results, and applicable fees. If you intend to operate a plumbing contracting business, you must also obtain a Plumbing Contractor license from Aurora, which typically requires master plumber status, proof of insurance (minimum $1M/$2M GL and Workers' Comp), and a contractor registration fee. This license is required before permits can be pulled in your company's name.
Maintain License and Complete Renewals
Renew your Aurora plumbing license per the city's renewal schedule (annually or biennially — confirm current cycle with Building Division). Stay current on Illinois State Plumbing Code updates, as code changes may affect renewal requirements. Maintain continuous insurance coverage and provide updated COIs at renewal. Lapsed licenses must be reinstated before performing any permitted work.
About This Market
Aurora's plumbing market is active and competitive. The city sits at the edge of Chicago's western suburbs with a dense residential base, active multifamily development along the Fox Valley corridor, and ongoing commercial build-out near the Foxvale development zone. Demand is steady year-round, with predictable spikes tied to new construction starts and weather-driven emergency calls. With approximately 4,147 licensed plumbing establishments operating across Illinois (Census data), the Chicago metro sees significant contractor density, which keeps pricing competitive on standard residential work. That said, Aurora's older housing stock — much of it built pre-1980 — drives consistent demand for sewer line replacements, galvanized pipe repiping, and sump pump upgrades, which are higher-margin jobs. Labor costs in this market track close to Chicago metro rates, and material costs have remained elevated post-pandemic, pushing project minimums up across the board. Homeowners in Aurora are generally price-aware but will pay for licensed, permitted work when they understand the stakes.
