Plumbing Contractor License in Vermont: Requirements, Qualifier, Bond and Exams
Our research found no separate plumbing contractor license in Vermont: the state licenses individual plumbers — masters, journeymen and three specialists — through the Division of Fire Safety's Plumber's Examining Board, and the plumbing statute provides that a specialty business may hire or employ only people licensed in the specialty of the business.
Residential contractors have had to register with the Office of Professional Regulation since April 1, 2023.
This page sets out what a plumbing business owes instead: a licensed crew, exams, fees, endorsement and the qualifier question.

Does Vermont license plumbing contractors statewide, or only locally?
It is a statewide system, and the licenses land on people rather than firms.
Vermont licenses plumbers statewide through the Division of Fire Safety's Plumber's Examining Board, but our research found no separate plumbing contractor license for the business: the Division of Fire Safety's ledger lists individual licenses only, and the plumbing statute licenses people.
What binds the business is its crew.
On the business side, the rule the statute gives us is about staffing: a specialty business may hire or employ only people licensed in the specialty of the business, and employing unlicensed workers for plumbing carries fines up to $1,000 per offense.
One statewide filing may touch a plumbing business: since April 1, 2023, Vermont has required residential contractors to register with the Office of Professional Regulation (OPR) under Act 182.
Because the no-contractor-license finding is inferred from the ledger and the statute rather than stated by either, confirm how your business should be organized with the Board and OPR before you bid work.
Which agency issues the license, and what are the classes?
No Vermont agency issues a plumbing contractor license in our research, so the classes to know are on the individual side.
The Division of Fire Safety's Plumber's Examining Board issues the Plumbing Master (PM), the Plumbing Journeyman (PJ), and three specialist licenses: P1 Water Heater, P2 Heating System and P3 Water Treatment.
A specialist may work only in the specialty the license names.
The Office of Professional Regulation sits alongside, not above: since April 1, 2023 it has run the residential contractor registration created by Act 182, which is a registration for residential contractors rather than a plumbing license class.
Who can be the qualifier, and what experience do they need?
Vermont has no named qualifier role in our research: we found no contractor license for an individual to qualify the business through.
The closest equivalent is your licensed crew.
In the statute's own words, a specialty business may hire or employ only people licensed in the specialty of the business — the licenses inside the firm are what let it operate.
Growing one runs on the Board's ladder.
A journeyman exam candidate documents a plumbing apprenticeship verified by the Vermont Apprenticeship Council, or equivalent training and experience acceptable to the Board; a master exam candidate must have held a Vermont journeyman plumber license for at least 12 months, or equivalent training and experience acceptable to the Board.
“A specialty business may hire or employ only people licensed in the specialty of the business.”
Which exams must be passed: trade, and business and law?
Our research found no business-and-law exam and no contractor license for one to attach to.
The exams that matter are the ones your staff sit for their own licenses: Vermont plumbing exams are ICC exams delivered through Prov — the Division of Fire Safety links plumbing testing to ICC and publishes a 2026 Prov bulletin, and the exact split between the two vendors is not confirmed in our research.
Every new license also carries the Vermont Energy Goals education module, required of each new or renewing Vermont trade license — plumbing included — since July 1, 2021.
What bond and insurance does Vermont require?
Our research did not establish a bond or insurance requirement for a Vermont plumbing business.
The business rule the statute gives us is about staffing, not financing, and the residential contractor registration's requirements were not confirmed in our research either — its threshold and fees remain unconfirmed.
Ask the Plumber's Examining Board and OPR what financial filings apply to your firm before you bid.
What does it cost, and how often is it renewed?
There is no contractor license fee to budget in our research, because our research found no contractor license.
The costs run through your staff's licenses, and the statute sets them: $120 for a master plumber license, $90 for a journeyman and $50 for a specialist, the same amounts at renewal.
Individual plumbing licenses are valid for two years, and renewal requires 8 hours of Board-approved training within the previous 24 months.
The OPR residential contractor registration fee was not confirmed in our research, so price it as unknown until you ask OPR.
Does Vermont have reciprocity with other states?
Our research found no reciprocity track for a plumbing business, and no business license for one to ride on.
The movement Vermont guarantees is on the individual side, and it is mandatory endorsement rather than a negotiated agreement: Vermont must issue plumbing licenses by endorsement to people licensed in good standing in another US jurisdiction for at least three years.
One more route sits in the same statute: service members and veterans with the 12K Plumber designation who completed at least 8,000 hours and four years of active-duty field work are issued a journeyman plumber license without an exam.
Confirm endorsement paperwork with the Board rather than assuming agreement-based reciprocity.
“who have been licensed in good standing in another jurisdiction within the United States for at least three years”
What happens if your qualifier leaves?
There is no state qualifier of record in our research — no named individual whose departure triggers a notification clock or a replacement deadline.
The exposure is your crew.
A specialty business may hire or employ only people licensed in the specialty of the business, and employing unlicensed workers for plumbing carries fines up to $1,000 per offense, so a specialty business whose licensed plumbers resign cannot legally backfill with unlicensed help.
Our research did not find a Vermont rule on what a business files when licensed staff leave, so ask the Plumber's Examining Board before a resignation rather than after, and recruit replacements through the endorsement route while the departure is still a plan.
Is there a job-size threshold below which no license is needed?
Our research confirmed no job-value threshold that exempts a plumbing business from licensing — we could not confirm the threshold for the OPR residential contractor registration either, though it is commonly reported as jobs over $10,000.
The statutory carve-out we did find runs on ownership rather than job size: Vermont exempts owners doing plumbing in their own owner-occupied single-family home from the plumbing license requirement.
An owner working on their own house and a business bidding that same house are therefore different situations.
What other rules and records should a Vermont plumbing business know?
The code your crews work to is the 2021 International Plumbing Code, adopted with the Vermont Plumbing Rules, 2025 edition.
Vermont also publishes a master list of trade license and certification holders on data.vermont.gov, which is where customers and general contractors can confirm that your plumbers are licensed.

Frequently Asked Questions
Do you need a contractor's license to do plumbing in Vermont?
Our research found no separate plumbing contractor license in Vermont.
The state licenses individual plumbers through the Division of Fire Safety's Plumber's Examining Board, and the plumbing statute provides that a specialty business may hire or employ only people licensed in the specialty of the business — employing unlicensed workers for plumbing carries fines up to $1,000 per offense.
Since April 1, 2023, residential contractors have also had to register with the Office of Professional Regulation.
What is the Vermont equivalent of a qualifier for a plumbing company?
Vermont has no named qualifier role in our research.
The business stands on its licensed crew: a specialty business may hire or employ only people licensed in the specialty of the business.
The closest planning equivalent is keeping licensed plumbers inside the firm — a master exam candidate must have held a Vermont journeyman plumber license for at least 12 months, or equivalent training and experience acceptable to the Board, and journeyman candidates document an apprenticeship verified by the Vermont Apprenticeship Council or equivalent training and experience acceptable to the Board.
Is there a Vermont plumbing contractor bond or insurance requirement?
Our research did not establish one for plumbing businesses.
The business rule the statute gives us is the licensed-staff rule and its fines — up to $1,000 per offense for employing unlicensed workers — not a bond or insurance filing.
The residential contractor registration with the Office of Professional Regulation may carry its own requirements, but its threshold and fees were not confirmed in our research.
Ask the Plumber's Examining Board and OPR before you bid.
Can Vermont endorse a plumber licensed in another state?
Yes, and the statute makes it mandatory: Vermont must issue plumbing licenses by endorsement to people licensed in good standing in another US jurisdiction for at least three years.
For a plumbing business that is a staffing tool — an experienced out-of-state hire can be endorsed rather than built from an apprenticeship.
Confirm the endorsement paperwork with the Plumber's Examining Board rather than assuming a negotiated reciprocity agreement.
What happens if my licensed plumber quits?
Vermont has no state qualifier of record in our research, so we found no notification or replacement deadline.
The constraint is the staffing rule: a specialty business may hire or employ only people licensed in the specialty of the business, and employing unlicensed workers for plumbing carries fines up to $1,000 per offense.
Ask the Board what applies while you recruit, and consider endorsement for an out-of-state replacement licensed in good standing in another US jurisdiction for at least three years.
