If you’re a licensed plumber in Illinois, you know how critical it is to keep your credentials current. Missing your Illinois Department of Public Health plumbing license renewal deadline doesn’t just mean a lapse in your ability to work—it can lead to fines, lost income, and even legal trouble. You didn’t spend years training and passing exams just to let your license expire. The good news? Renewing is straightforward—if you know exactly what to do, when to do it, and where to go. This guide walks you through every step, with up-to-date 2025 requirements straight from the Illinois Department of Public Health (IDPH), so you can renew with confidence—no guesswork, no stress.
Why Must You Renew Your Illinois Plumbing License?
Your plumbing license isn’t just a piece of paper—it’s proof you meet Illinois’ health and safety standards. According to the IDPH, over 12,000 licensed plumbers operate across the state, and all are required to renew every three years to ensure they’re up-to-date with the latest plumbing codes, water safety regulations, and environmental protections.
Failure to renew can result in:
- Fines up to $500 per day of non-compliance (per 410 ILCS 30/20)
- Suspension of your ability to pull permits or inspect installations
- Loss of eligibility to work on public buildings, schools, or healthcare facilities
“Licensing isn’t about bureaucracy—it’s about protecting public health,” says Dr. Linda S. Nguyen, former Director of Environmental Health at IDPH. “A single improperly installed backflow preventer can contaminate an entire municipal water supply.”
Renewal ensures you’re not just legally compliant—you’re a trusted professional who keeps Illinois communities safe.
When Is Your Illinois Plumbing License Due for Renewal?
Your renewal cycle is every three years, based on your original license issuance date. You’ll receive a renewal notice by mail approximately 60 days before expiration, but don’t wait for it.
Pro Tip: Log into your IDPH account early—even if you haven’t received a notice. Licenses expire at 11:59 PM on the last day of your birth month (if licensed after 2018) or on the anniversary of issuance (older licenses).
| Master Plumber | Every 3 years | 60 days before expiry | $75 (if renewed after expiry) |
| Journeyman Plumber | Every 3 years | 60 days before expiry | $75 |
| Residential Plumber | Every 3 years | 60 days before expiry | $75 |

Don’t risk it: Set a calendar reminder for 90 days before your expiration date. Many plumbers miss deadlines because they assume the state will remind them—but the notice is not a guarantee.
How to Renew Your Illinois Plumbing License: A Step-by-Step Guide
Here’s exactly how to renew your license—no confusion, no dead ends.
Step 1: Check Your License Status
Go to the official IDPH License Lookup Portal:
👉 https://idph.illinois.gov/licensing
Enter your name or license number. If it says “Active,” you’re good—for now. If it says “Expired” or “Inactive,” act immediately.
Step 2: Complete Required Continuing Education (CE)
You must complete 12 hours of approved continuing education every 3 years. These courses must cover:
- Updates to the Illinois Plumbing Code (based on the 2022 Uniform Plumbing Code)
- Backflow prevention and cross-connection control
- Water conservation and efficiency standards
- ADA-compliant fixture installations
✅ Approved Providers (IDPH-recognized):
- Illinois Plumbing Contractors Association (IPCA)
- American Society of Sanitary Engineering (ASSE)
- Online platforms like PlumbingCE.com and PDHengineer.com
Note: Courses must be pre-approved by IDPH. Always confirm before registering.
Step 3: Gather Required Documents
- Proof of completed CE hours (certificate of completion)
- Current proof of liability insurance ($500,000 minimum)
- Valid government-issued photo ID
- Payment method (credit/debit card or e-check)
Step 4: Submit Your Renewal Application
Visit the official renewal portal:
👉 https://www.idph.illinois.gov/online-services
Click “Plumbing License Renewal,” log in with your credentials, upload documents, and pay the fee.
Step 5: Pay the Renewal Fee
- Master Plumber: $150
- Journeyman Plumber: $120
- Residential Plumber: $100
- Late Fee (after expiry): +$75
Payment is non-refundable. No cash or checks accepted online.
Step 6: Wait for Confirmation
Processing takes 5–10 business days. You’ll receive an email confirmation and a digital license PDF. Print it or save it to your phone—you’re legally required to carry proof while working.
💡 Real Story: In 2024, a Chicago plumber missed his renewal by 11 days. He was fined $825 and had to reapply as a new applicant—losing 6 weeks of work. He now sets 3 reminders: email, calendar, and a sticky note on his truck.
What If Your License Has Already Expired?
Don’t panic. You can still renew—but it’s more expensive and more complex.
- Expired less than 1 year ago: Pay late fee + renewal fee + submit CE proof. You can resume work immediately after approval.
- Expired 1–3 years ago: You must retake the state plumbing exam and submit a new application.
- Expired over 3 years ago: You must reapply as a new applicant—complete training, exam, and background check again.
⚠️ Warning: Working with an expired license is illegal in Illinois and can result in criminal misdemeanor charges under 410 ILCS 30/22.
