Virginia Master Plumber licensing, explained

About the Virginia Master Plumber license

Virginia licenses plumbers through the Virginia Board for Contractors (DPOR). The Master Plumber is the senior plumbing credential. It generally requires you to first hold a journeyman plumber license, accumulate additional documented experience as a licensed journeyman, and pass a more demanding exam that adds system design, sizing, code administration, and often business-and-law content. A master may design plumbing systems, pull permits, supervise journeymen and apprentices, and serve as the qualifying individual for a licensed plumbing contractor.

Your exam is built on the International Plumbing Code (IPC) 2021 as listed in the PSI CIB (the exam is written to IPC 2021). This sitting is written to the International Plumbing Code (IPC) 2021, the listed plumber book in the PSI Individual License CIB. UPC tables are the wrong book.

Know these scope facts cold: the license is held by the individual; most work requires a permit and inspection (rough-in/top-out and final); you must work within the classification you hold; and unlicensed or out-of-scope plumbing work is a violation that can cost you the license and carry penalties. Plumbing protects public health — the exam constantly returns to the two core purposes of the code: deliver safe potable water and remove waste without contaminating that water.

How Virginia licensing works

  • Experience: documented hours in the trade (apprentice and journeyman time); the master license requires journeyman time on top of the base requirement.
  • Education: approved instruction hours or completion of an approved apprenticeship program.
  • Application: submit the application, fees, and proof of experience (often signed off by a master plumber or employer) before you are approved to sit.
  • Exam vendor: PSI. The passing score is 60 of 80 (75 percent) on the 7/23/2026 PSI CIB. Business and law is the separate Designated Employee paper (course 182559), not this 80-item plumber sitting.
  • Renewal: licenses renew on a fixed cycle and usually require continuing education, including code-update hours when a new code edition is adopted.

This is the opening of the full study guide. The complete guide continues into code navigation, worked calculations and solved exam questions.
