R.I. Gen. Laws § 5-20-8 bars anyone from engaging in the business of plumbing, employing journeypersons or apprentices, contracting for plumbing installation or repair, or advertising plumbing services without a DLT master plumber license, and the license number must appear on contracts, bids, and permits. A corporation or firm may only do so if a licensed master is an officer or principal continuously supervising the work, or if it holds a DLT plumbing contractor license with a contractor master or an employed master plumber (§ 5-20-12). A journeyperson applicant must have been a registered apprentice for at least four years with 8,000 hours of on-the-job training in a five-year period, including 576 hours of related instruction (§ 5-20-17); a master applicant must have held a journeyperson license for at least one year while employed by a master (§ 5-20-16).
Applications carry a $75 nonrefundable fee (§§ 5-20-16, 5-20-17). Licenses expire on the licensee's birthday in odd or even years; master renewals are $240 and journeyperson renewals $72 for two years, plus a $12 per month delinquency assessment for late renewal (§ 5-20-23). Masters and journeypersons must complete board-set continuing education of up to 15 hours before renewal (§ 5-20-23(f)). DLT-licensed plumbing businesses are exempt from CRLB registration except for its insurance requirement (§ 5-65-2(a)(10)).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Licensing is state-only through DLT; plumbing permits and inspections are issued by each city or town (there is no county layer in Rhode Island), and the master's license number must be affixed to the permit (§ 5-20-8).

DLT-licensed plumbing businesses working within their license are exempt from CRLB registration except for the insurance requirement (§ 5-65-2(a)(10)).
