Virginia stacks two DPOR credentials on every plumbing job: the individual tradesman license for whoever turns the wrench (§ 54.1-1129) and the firm's Class A, B, or C contractor license with the PLB classification, whose Qualified Individual must hold a Master Plumbing license.
The newest rung is the residential plumber license, available since April 1, 2025: two to six years of experience depending on vocational training, limited to dwellings and townhouses, and after three years it counts toward master eligibility. Gas piping sits outside plumbing — the PLB classification expressly excludes it, so gas lines need the separate gas-fitting designation.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
DPOR's license is statewide, but the application itself makes every firm affirm it will comply with local licensing in each city, county, and town where it works. Two local desks matter. First, the building department: Virginia's Uniform Statewide Building Code supersedes local building codes (§ 36-98) but is enforced locally (§ 36-105), and § 54.1-1111 bars the permit desk from issuing a permit without proof of a DPOR license or a written statement that you are exempt. Virginia cities are independent of counties (§ 15.2-102), so in Virginia Beach, Norfolk, Chesapeake, Richmond, or Alexandria the city's own building department is the desk — no county is involved — while in counties such as Arlington and Loudoun the county building department handles county permits. Towns sit inside their counties. Second, the commissioner of the revenue: the local business license (BPOL) is owed where your office is, and any other locality may require its own once your work there tops $25,000 in a year (§ 58.1-3715); that office also needs proof of your DPOR license or an affidavit of exemption. Plumbing permits, inspections, and any locally required cross-connection testing schedules run through the city or county; the license itself is DPOR's alone.
The local offices section below names the exact permit desk for every Virginia county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Since April 1, 2025, a residential plumber license needs as little as two years plus 160 hours of training — and three years holding it qualifies you for the master exam.
The PLB classification excludes gas piping. Water heaters and ranges on gas mean adding the gas-fitting designation for both the individual and the firm.
Under 2026's House Bill 30, DPOR adds a $7.25-per-year technology fee to certain fees from July 1, 2026 through June 30, 2030 — that is the $14.50 baked into each two-year application total.

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Practicing as a plumber without a DPOR license is a Class 1 misdemeanor — up to 12 months and $2,500.
Contracting or bidding on work for another without a license, or without the proper class for the value of the work, is a Class 1 misdemeanor — up to 12 months in jail and a $2,500 fine — plus a fine of up to $500 for every day in violation. In a consumer transaction it is also a Virginia Consumer Protection Act violation.
A construction contract entered by an unlicensed contractor is not enforceable by that contractor unless he substantially performed in good faith AND did not actually know a license was required. Letting a license lapse creates a rebuttable presumption that you knew.

Pending verification: DPOR's Tradesmen page describes continuing education per 'every 2-year term', but 18VAC50-30-120 (amended effective August 1, 2025) sets a three-year tradesman license term; this record follows the regulation · Whether the technology fee is added to the $105 added-designation fee and the $160 renewal fee · Residential plumber exam fee at PSI (the published $100/$125 figures are for journeyman and master exams)
