State of Utah Plumbing Rule Changes Summary

Effective January 9, 2020

“PLUMBER LICENSING ACT RULE” AMENDMENTS:   In response to 2019, H.B.187 and H.B. 226, this filing is recommended by the Plumbers Licensing Board and the Construction Services Commission to clarify current requirements and conform the rule to current practices in the industry. Additionally, this filing removes certain requirements that the Board and the Commission have found to be outdated and unnecessarily arduous.

Section R156-55c-102:

  • Clarifies the definition of “immediate supervision” with respect to residential plumbing work. Now requires the supervising plumber to be available to provide direction and oversight when not physically present on the same project or job site.

Section R156-55c-302a:

  • Increases the accepted hours of work experience to be credited for each 12 month period from 2,000 to 3,000 hours.

Section R156-55c-302b:

  • Extends the 25-day waiting period after a failed exam to a 30-day waiting period, to alleviate confusion and create parity among the standards for all contractor professions; and
  • Deletes the requirement that an applicant pass all exams within a one-year period (the one-year “rolling clock” requirement).

Section R156-55c-302c:

  • This new section creates opportunities for “expedited licensure” and the appropriate placement of the apprentice plumber seeking education in an approved program.

R156-55c-302c. Qualifications – Expedited Licensure.

In accordance with Subsections 58-1-203(2) and 58-1-301(3), the requirements for expedited licensure pursuant to Subsections 58-55-302(3)(c)(iii) and 58-55-302(3)(d)(iii) are as follows:

(1) A licensed apprentice plumber may take the approved competency exams, in sequence beginning with 1A and continuing through 4B, to either satisfy the education requirement, or determine placement in a planned program of training approved by the Division.

(2) Division pre-approval is not required to sit for any competency exam.

(3) The applicant may register directly with the Division’s approved exam provider to sit for a competency exam.

(4) The applicant may attempt each competency exam one time.

(5) Admission to the subsequent competency exam is permitted after obtaining a minimum score of 70%.

(6) Placement in a planned program of training is determined when the applicant scores below 70% on the corresponding competency exam.

(7) Upon completion of all qualifying competency exams, the applicant may sit for the Utah journeyman or residential journeyman plumber exams.

Section R156-55c-303:

  • Requires all licensees renew their license in an online form approved by the Division, except as permitted by the Division in writing.

Section R156-55c-304:

  • Redefines OSHA training as Core CE (previously OSHA training was defined as Professional CE).

Section R156-55c-401:

  • Pursuant to Subsection 58-55-302(3), clarifies that an apprentice beginning in the fourth and succeeding years of an apprenticeship shall work under immediate supervision in accordance with Subsection R156-55c-102(1).
  • Clarifies the number of apprentice plumbers a licensed supervisor may have on:
  • Non-residential projects (increases to 3:1); and
  • Residential projects (increases to 3:1).

Section R156-55b-501:

  • Includes as unprofessional conduct, (“ignorantia legis neminem excusat”) failing as a licensee to be knowledgeable of the plumber licensing laws and rules.


In addition the Plumbing Licensing Board has changed the core hours required for renewal to include OSHA Safety Topics. In other words the 12 hours required, 8 core and 4 professional can have safety topics included in the 8 hours, along with building codes as topics for core training.  Hours didn’t change, just the makeup of topics.
