Vermont Master Plumber License Requirements (2026)

The Vermont Plumbers' Licensing Board, administered by the Office of Professional Regulation (OPR), licenses individual plumbers statewide under 26 V.S.A. Chapter 37. Vermont issues three primary tiers — Apprentice Plumber (registered while learning under a licensed plumber), Journeyman Plumber (independent installer under a Master), and Master Plumber (authorized to design, supervise, contract, and pull state plumbing permits). Vermont enforces the International Plumbing Code (IPC) as adopted by the Department of Public Safety, Division of Fire Safety, with state amendments. State plumbing permits and inspections are required for new construction and most alterations except in municipalities operating their own approved inspection program.

Governing Authority

Under 26 V.S.A. (Professions and Occupations); Vermont Act 21 of 2019 (Residential Contractor Registration); Administrative Rules of the Electricians and Plumbers Licensing Boards, Vermont Office of Professional Regulation (OPR) is the body that issues this license and enforces compliance with it. The Vermont Office of Professional Regulation, housed within the Secretary of State, administers the Residential Contractor Registration program and supports the Electricians' Licensing Board and the Plumbers' Licensing Board, which set examination, experience, and discipline rules for the licensed trades.

Good moral character

OPR may deny, condition, or revoke a license for unprofessional conduct under 3 V.S.A. § 129a.

Background investigation

Disclosure of prior license discipline and trade-related criminal convictions is required on the application.

Experience & Education Matrix

Eligibility requires 4 years of Journeyman: 8,000 hours (approximately 4 years) of qualifying experience as a registered apprentice under a licensed Master Plumber. Master: an additional 2,000 hours (approximately 1 year) of journey-level experience after passing the journeyman exam., documented and independently verifiable. Payroll, tax, project, and supervisor records are the usual proof the board will accept.

Accepted proof of experience or eligibility

OPR Apprentice Registration on file for the entire qualifying period
Hour logs and W-2/1099 records signed by the supervising Master Plumber
Approved plumbing apprenticeship program completion certificate (where applicable)

Education substitution

Hours from an approved plumbing apprenticeship or accredited plumbing program may count toward the 8,000-hour journeyman requirement under Plumbers' Licensing Board rules.

Examination Structure

The licensing examination is delivered by Prometric (under contract to OPR / Vermont Plumbers' Licensing Board). All of the following parts must be cleared prior to issuance:

Vermont Journeyman Plumber Examination — International Plumbing Code, Vermont rules — 80 questions, 240 minutes, passing score 70%
Vermont Master Plumber Examination — IPC, business and law (taken after the journeyman license is held) — 100 questions, 240 minutes, passing score 70%

Examination fee: Examination fee set by Prometric and posted in the current OPR fee schedule.

Retake policy: Failed examinations may be re-taken under OPR scheduling rules. Each application remains valid for one year.

Insurance & Financial Security

This credential carries no state-level surety bond requirement under the cited sources. Individual jobs may still trigger a permit or public-works bond, which should be verified before bidding.

General liability

OPR does not impose a state-level general liability minimum on individual plumber licenses. Most owners and general contractors contractually require $1,000,000/$2,000,000.

Workers' compensation

Workers' compensation insurance is required under 21 V.S.A. Chapter 9 for any business with employees in Vermont.

Additional financial requirements

No financial statement requirement for individual plumber licenses.

Reciprocity and Endorsement

Vermont does not accept the NASCLA Accredited Examination for this classification.

Reciprocal State	Accepted Exam	Conditions
New Hampshire	Reviewed individually	OPR may accept an active New Hampshire Master Plumber license under endorsement after verification.
Maine	Reviewed individually	OPR may accept an active Maine Master Plumber license under endorsement after verification.

Vermont evaluates out-of-state Master Plumber licenses on a case-by-case basis under its endorsement process. Active licensure in good standing in a state with substantially equivalent requirements is the typical path.

Common Filing Mistakes

Working from the cited board instructions, here are the snags most likely to trip up a Vermont Plumber filing.

Working without an Apprentice registration

Hours logged before registering as an apprentice do not count toward the journeyman requirement.

Skipping the journeyman step

Vermont enforces a strict apprentice → journeyman → master sequence. Direct entry to Master is not allowed.

Studying the wrong code

Vermont uses the IPC with state amendments. Candidates from UPC states often study the wrong reference.

Pulling permits without a Master

Only Master Plumbers may pull state plumbing permits. Journeymen and apprentices cannot pull permits in their own name.

Missing continuing education

Renewal is contingent on Board-required CE. Missing CE blocks renewal and lapses the license.
