How do you get a Rhode Island plumbing license?
Rhode Island licenses plumbing work at three practical levels: registered apprentice, licensed journeyperson, and licensed master. The state plumbing statute index separates the definitions, permitted work, qualifications, exams, and renewals for those credentials.
The short answer: register before working as an apprentice, complete and document the required training, qualify for and pass the journeyperson exam, then hold the journeyperson license long enough to qualify for the master exam. DLT issues the master and journeyperson licenses after successful examination and approval. (R.I. Gen. Laws § 5-20-21) Cities and towns may still require permits and inspections for individual jobs.
If you are comparing this route with another state, start with our general plumbing-license path. Rhode Island has unusually specific statutory hour, instruction, filing-deadline, and renewal rules, so generic trade advice is not enough.
Apprentice, journeyperson, and master licenses
Apprentice plumber
An apprentice plumber is an employee registered under § 28-45-13 whose principal occupation is service with a master plumber to learn plumbing. (R.I. Gen. Laws § 5-20-5) An apprentice must carry a current DLT registration certificate while working. (R.I. Gen. Laws § 5-20-10)
Journeyperson plumber
A journeyperson plumber is an employee, other than an apprentice, whose principal occupation is installing, maintaining, or repairing plumbing. (R.I. Gen. Laws § 5-20-4) The journeyperson must hold and carry a current license and work for the properly licensed master permit holder. (R.I. Gen. Laws § 5-20-9)
Master plumber
A master plumber is the independent-contractor level and may employ journeyperson plumbers, apprentices, or others to assist with plumbing work. (R.I. Gen. Laws § 5-20-3) A current master license is required to contract for plumbing work, employ journeypersons or apprentices, or advertise as a master plumber. (R.I. Gen. Laws § 5-20-8)
Training and experience requirements
The standard registered-apprenticeship route requires at least 8,000 hours over no less than five years under direct supervision and instruction. (R.I. Gen. Laws § 5-20-25)
For the journeyperson exam, the statute requires 8,000 hours of on-the-job training during a five-year period, including 576 hours of related instruction. (R.I. Gen. Laws § 5-20-17) The apprentice registration must have been held for at least four years before filing. (R.I. Gen. Laws § 5-20-17) The law provides separate education-based and equivalent out-of-state-license routes, so applicants using one of those routes should match their documents to the exact statutory option rather than assume the standard apprenticeship rule applies unchanged.
Apprentices seeking exam eligibility must document completion with related-instruction transcripts and employer work-record books, or other evidence DLT finds reasonably satisfactory. (R.I. Gen. Laws § 5-20-25.1) Keep the registration, school records, work record books, and employer affidavits together while training. Rebuilding five years of records at application time is avoidable.
Application and exam process
- Register the apprenticeship with DLT before counting the standard training route.
- Complete the required supervised work and related instruction, keeping work record books and transcripts.
- File the DLT journeyperson application with the supporting evidence and application fee.
- Take the journeyperson examination after DLT accepts the application.
- After licensing, work under the proper master-permit holder and keep the license current.
- Apply for the master examination after meeting the master-level experience rule.
The journeyperson application fee is $75. The completed application must reach DLT at least 15 days before the exam date. (R.I. Gen. Laws § 5-20-17) The standard master-exam route requires an active Rhode Island journeyperson license held for at least one year, an employment affidavit for that period, and a $75 nonrefundable application fee. (R.I. Gen. Laws § 5-20-16) Under the standard statutory route, a master applicant must also be a U.S. citizen or legal resident. (R.I. Gen. Laws § 5-20-16) A completed master application must be filed at least 30 days before the examination date. (R.I. Gen. Laws § 5-20-16)
DLT must provide master and journeyperson plumbing examinations at least three times each year. (R.I. Gen. Laws § 5-20-20) That statutory minimum does not promise a seat on a particular date, so build the filing deadline into the schedule.
Business licensing and local permits
A state credential does not remove local job controls. Rhode Island law allows any city or town to use plumbing inspectors, require installation or repair permits, and collect plumbing permit fees. (R.I. Gen. Laws § 5-20-26) Ask the municipality about the permit, inspection sequence, adopted code, and local fee before work begins.
For a sole operator, the master credential is the business-facing license. For a corporation, partnership, association, or other entity, the structure is more specific: the entity needs either a qualifying licensed master in the required principal role or its own valid plumbing contractor license with continuous master-level supervision. (R.I. Gen. Laws § 5-20-12) An entity license alone does not authorize an unlicensed officer, employee, or agent to perform plumbing installation, maintenance, or repair. (R.I. Gen. Laws § 5-20-12)
A master plumber must place the plumbing license number on contracts, bids, and applicable permits. (R.I. Gen. Laws § 5-20-8) If the license is part of a broader company launch, the construction-business startup checklist covers the nontrade pieces that this plumbing credential does not replace.
Application fees, renewal, and continuing education
Rhode Island separates application fees, license and renewal fees, exam-related costs, local permit fees, and training costs. Budget them separately rather than treating the $75 application fee as the total cost. Our guide to the full cost of contractor licensing explains the same budgeting problem across trades.
Journeyperson licenses renew by the licensee’s second birthday after issuance for a $72 biennial renewal fee. (R.I. Gen. Laws § 5-20-23) Master and journeyperson expiration years track the licensee’s birth-year parity and expire on the birthday in the matching odd or even year. (R.I. Gen. Laws § 5-20-23)
A master license that lapses may be reinstated for up to two years with the $240 current biennial renewal fee, outstanding license fees, and a $12-per-month delinquency assessment. (R.I. Gen. Laws § 5-20-23) A journeyperson reinstatement within that window uses the $72 current biennial renewal fee, outstanding license fees, and the same monthly assessment. (R.I. Gen. Laws § 5-20-23) A license not renewed within two years after expiration is forfeited, and the former licensee must apply for an examination before receiving a new license. (R.I. Gen. Laws § 5-20-23)
Master and journeyperson plumbers must complete board-determined continuing education before renewal or reinstatement, capped by statute at 15 hours, unless an exemption applies. (R.I. Gen. Laws § 5-20-23)
Using an out-of-state plumbing license
Rhode Island law provides an out-of-state qualification route, not a blanket automatic transfer. A journeyperson applicant may qualify with a license from another state when that state’s requirements are the same as Rhode Island’s requirements. (R.I. Gen. Laws § 5-20-17)
Build the file around comparability. Obtain official license verification, the issuing state requirements in effect when you qualified, exam history, apprenticeship or education records, and employment documentation. DLT must be able to compare the other credential with the Rhode Island journeyperson standard.
The master statute also lets DLT waive its standard prerequisites when the applicant supplies acceptable evidence of equivalent skill, expertise, education, experience, training, and other qualifications. (R.I. Gen. Laws § 5-20-16) That is discretionary evidence review, not a promise that an out-of-state master license converts automatically.
