Navigating Illinois' plumbing license requirements can seem complex due to its multiple license types, but rest assured, the Illinois Department of Public Health (IDPH) clearly outlines every step, from apprenticeship to contractor registration. This guide breaks down the official requirements, fees, and processes to help you get licensed and start working legally in the state. Whether you're beginning as an apprentice or registering your own plumbing business, this guide provides the specific details you need to succeed.
Do You Need a Plumbing License in Illinois?
Yes, the Illinois Plumbing License Law (225 ILCS 320) requires individuals performing plumbing work in Illinois to hold a valid license or registration issued by the Illinois Department of Public Health (IDPH). This statewide requirement ensures that all plumbing work meets established safety and public health standards outlined in the Illinois Plumbing Code. The law defines "plumbing" broadly, covering the installation, repair, and maintenance of pipes, fixtures, and appliances for water distribution and drainage systems in connection with any building or structure.
Illinois Plumbing License Types & Tiers
The Illinois Department of Public Health (IDPH) issues several types of plumbing licenses and registrations, each with a specific scope of work.
Apprentice Plumber (Registration)
An Apprentice Plumber registration allows an individual to learn the trade by performing plumbing work under the direct supervision of a licensed plumber. Apprentices are required to be enrolled in an approved course of instruction and must complete a minimum apprenticeship period before they can apply for the Plumber license examination.
Plumber (Journeyman License)
A Plumber license, often referred to as a journeyman license, authorizes an individual who has completed their apprenticeship and passed the state exam to perform plumbing work. Licensed plumbers must work under the employment and supervision of a registered plumbing contractor.
Plumbing Contractor (Registration)
A Plumbing Contractor registration is required for any individual or business entity that employs licensed plumbers and contracts with the public to perform plumbing work. To register as a plumbing contractor, an individual must hold a valid Illinois Plumber license and meet specific insurance and bonding requirements.
Irrigation Contractor (Registration)
An Irrigation Contractor registration is a specialized credential for individuals or businesses that install and maintain lawn irrigation systems. This registration is distinct from a full plumbing contractor registration and has its own application process and fees.
Retired Plumber (License)
This license status is available for plumbers who are no longer actively working in the trade but wish to maintain their license. A retired plumber is not permitted to perform any active plumbing work.
How to Become a Licensed Plumber in Illinois (Journeyman)
Becoming a licensed plumber in Illinois involves specific education, a multi-year apprenticeship, and passing a state examination administered by the IDPH.
Step 1: Meet Pre-Apprenticeship Requirements
Before you can begin your apprenticeship, you must meet the following educational prerequisites per IDPH requirements:
- Have completed at least two years of high school or its equivalent.
- Complete an approved course of instruction through a college, university, or trade school.
Step 2: Register as an Apprentice Plumber
Once you have met the educational requirements and secured a position with a licensed plumbing contractor, you must register as an apprentice with the IDPH. This involves submitting an application and paying the required registration fee.
Step 3: Complete Required Apprenticeship Experience
Applicants for the Plumber license must complete a minimum of four years (48 months) of employment as a licensed apprentice plumber. During this time, you will gain hands-on experience working under the supervision of a licensed plumber.
Step 4: Apply for the Plumber License Examination
After completing your apprenticeship, you are eligible to apply for the Plumber License Examination. This requires submitting a completed application form to the IDPH, which includes an attestation of your completed apprenticeship experience from your supervising plumber.
Step 5: Pass the Illinois Plumber Licensing Exam
The Illinois Department of Public Health (IDPH) administers the state licensing exam. The exam tests your knowledge of the Illinois Plumbing Code, industry best practices, and the technical skills required to perform plumbing work safely and correctly. Specific details about the exam format and scheduling will be provided after your application is approved.
Step 6: Receive Your Illinois Plumber License
Upon successfully passing the state examination, the IDPH will issue your Illinois Plumber license. Licenses must be renewed annually by April 30.
How to Register as an Illinois Plumbing Contractor
Operating as a plumbing contractor in Illinois requires an annual registration with the IDPH, which is separate from the individual plumber license.

Contractors with no employees may be exempt from the Workers' Compensation requirement by submitting an Affidavit of No Employees and Opt-Out form.
Step 3: Secure a Surety Bond or Letter of Credit
You must obtain a surety or indemnification bond in the amount of $20,000. The bond must name the Illinois Department of Public Health as the beneficiary. As an alternative to a bond, you may submit a letter of credit for the same amount.
Step 4: Complete the Plumbing Contractor Application
Submit the "Application for Registration or Renewal" for plumbing contractors to the IDPH. You must include all required attachments, such as your proof of insurance and the original surety bond.
Step 5: Pay Registration Fees

Illinois offers limited reciprocity for certain plumber licenses, including those from the City of Chicago and potentially other jurisdictions with equivalent requirements.
Reciprocity for City of Chicago Licensees
The IDPH has a specific application process for individuals who hold a plumber's license issued by the City of Chicago. This is because Chicago's municipal licensing system pre-dates the statewide act.
Reciprocity for Out-of-State Licensees
Under the Illinois Plumbing License Law, the IDPH may issue a license to an applicant who holds a valid license from another state or jurisdiction with "substantially equivalent requirements." Applicants should contact the IDPH directly to confirm if their out-of-state license qualifies and to understand the specific application process.
Verifying an Illinois Plumbing License
You can verify the status of a plumbing license or registration by contacting the Illinois Department of Public Health. Verifying that a plumber or contractor is properly licensed and registered is a crucial step to ensure they are qualified, insured, and legally authorized to perform work in the state.
Penalties for Unlicensed Plumbing Work in Illinois
Performing plumbing work without the required state license or registration is a violation of the Illinois Plumbing License Law. The law specifically prohibits unlicensed individuals or entities from advertising plumbing services. According to 225 ILCS 320 §5, a first offense for improper advertising is subject to a fine of up to $1,000. Subsequent offenses can lead to more severe penalties and legal action.
