Who licenses plumbers in Wisconsin?
Direct answer: Wisconsin generally requires a DSPS license to engage in or work at plumbing, with registration for apprentices and pipe layers, but Wis. Stat. § 145.06 lists specific exemptions. Wis. Stat. § 145.06 Those exemptions include qualifying owner work on an owner-occupied one-family home or farm building, subject to any local licensing ordinance; specified utility work; and minor repairs to faucets, valves, pipes, or appliances.
The ordinary progression is registered plumbing apprentice, licensed journeyman plumber, then licensed master plumber. The master credential matters because Wisconsin law requires a licensed master plumber to remain in charge of an installation. Wis. Stat. § 145.06
This guide covers the unrestricted journeyman and master path. DSPS also lists restricted appliance and restricted service credentials, which have narrower scopes.
Apprentice, journeyman, and master structure
The three core positions do different jobs:
- Plumbing apprentice: Holds an individual DSPS credential and works within a recognized apprenticeship contract. The current DSPS apprentice page says renewal depends on evidence that the person remains in an apprenticeship contract recognized under chapter 106. DSPS Plumbing Apprentice
- Journeyman plumber: Has completed the qualifying path and passed the required state examination. A journeyman is a licensed worker, but the law still places responsibility for the installation with a master plumber.
- Master plumber: May be in charge of plumbing installation and is responsible for proper installation under state law.
Credentials belong to individuals. Wisconsin law says plumbing licenses are issued only to individuals, not to a firm or corporation. Wisconsin Statute 145.06 If you plan to operate a broader construction business, compare the separate Wisconsin contractor credential guide.
Wisconsin journeyman plumber path
For the standard in-state route, an applicant for the journeyman examination must give DSPS satisfactory evidence of completing a plumbing apprenticeship under Wis. Stat. 106.025. Wisconsin Statute 145.07
The current DSPS page separates applicants by method. Its Wisconsin examination route is for someone who has never held a Wisconsin journeyman credential and has completed a Wisconsin plumbing apprenticeship. DSPS Journeyman Plumber The page also provides an “other application methods” route for applicants with an out-of-state apprenticeship or licensing history.
Practical sequence:
- Keep the apprenticeship contract and completion record.
- Create an individual LicensE account; plumber credentials require an individual account.
- Apply under the method that matches the record instead of assuming an out-of-state card transfers.
- Wait for DSPS qualification review before relying on an exam date.
For recordkeeping strategy, see contractor license experience verification.
Wisconsin master plumber path
Wisconsin law gives two direct ways to qualify for the master plumber examination. The applicant may document at least 1,000 hours per year for three or more years as a licensed Wisconsin journeyman plumber, or graduate in engineering from a school or college approved by DSPS. Wisconsin Statute 145.07
The current DSPS master page describes its Wisconsin examination method as the route for an applicant who has never held a Wisconsin master credential and has the required journeyman experience or engineering degree. DSPS Master Plumber It separately lists other methods, including comity plus examination and a route for a Wisconsin master credential previously exchanged for journeyman.
The hour rule is not “three calendar years after journeyman issuance” by itself. Each qualifying year needs the required hours. Build an annual experience record that can show dates, hours, credential status, employer, and responsible master.
Current Pearson exam and application process
Wisconsin uses a pre-exam LicensE application. The current DSPS trades exam page says initial and reinstatement trade applicants apply through LicensE; after DSPS deems the applicant eligible, the system provides scheduling instructions.
The current DSPS trades exam page says these exams are open book. The schedule lists Journeyman Plumber Part 1 and Part 2 separately. It also lists Master Plumber Part 1 and Part 2 separately. DSPS says all plumbing credential examinations are available only at the listed Wisconsin Pearson centers. Eligible candidates select a Pearson location through the open LicensE application, and availability controls test dates and times.
Use the credential page for eligibility and allowed references, then follow the current LicensE and Pearson instructions. This guide does not apply the separate SPS 305.09 department-administered timing and scoring provisions to the Pearson-only plumbing process without current DSPS confirmation.
Current fees, renewal, and timing
The current DSPS credential fee list separates the credential fee from the application fee. Journeyman Plumber is listed at a $180 initial credential fee plus a $10 application fee. Master Plumber is listed at a $500 initial credential fee plus a $20 application fee. DSPS says the total is calculated at the end of the LicensE application and that additional fees may apply.
Exam charges are separate. The current DSPS trade exam fee schedule lists each journeyman part at $90 paid to Pearson plus $20 paid to DSPS. DSPS trade exam fee schedule Each master part is $95 paid to Pearson plus $30 paid to DSPS. The schedule lists Part 1 and Part 2 for each credential, so budget for both parts rather than one exam charge.
For renewal, journeyman and master credentials are valid for four years and renew on March 31. Journeyman renewal is $180 and requires 24 continuing-education hours. Master renewal is $500 and requires 24 continuing-education hours. The fee list also shows a $25 late continuing-education fee when applicable and a $200 reinstatement fee when applicable. Plumbing Apprentice is listed at $15 for the credential and $15 for the application. Its renewal line shows a one-year term from issuance, a $15 renewal fee, and no continuing-education requirement. DSPS credential fee list
The minimum master-eligibility timeline is three qualifying journeyman years at 1,000 hours per year. Processing time then depends on document completeness, legal review where applicable, eligibility review, and Pearson exam scheduling. Do not promise a license date from the experience minimum alone.
Comity and out-of-state applicants
Wisconsin calls its out-of-state route comity, not automatic reciprocity. State law allows DSPS to accept someone for the appropriate examination without the ordinary section 145.07 evidence when the person holds a current license under another jurisdiction whose plumbing requirements DSPS finds equivalent, or has out-of-state practical experience DSPS finds equivalent. Wisconsin Statute 145.09
The separate mandatory journeyman route in Wis. Stat. 145.09(2m) requires all three conditions: a qualifying Wisconsin or out-of-state plumbing apprenticeship; passage of another state’s journeyman plumber examination; and at least five years of practice under a journeyman or equivalent license from a state whose licensing provisions DSPS finds substantially similar, with no related disciplinary action. Wisconsin Statute 145.09
Comity gets a qualified applicant to Wisconsin examination eligibility; it does not turn an out-of-state license into a Wisconsin license automatically. Submit the apprenticeship, exam, credential, practice, and discipline records requested for the selected DSPS application method. For the general distinction, read contractor license reciprocity.
