Virginia Plumbing Permits & Licensed Plumber Requirements Guide
In Virginia, all non-exempt plumbing work—including new installations, replacements, and major repairs—requires a valid permit and must be performed by a DPOR-licensed plumber. The Virginia Department of Professional and Occupational Regulation (DPOR) oversees master and journeyman plumbing licenses, as well as separate gasfitter credentials, all governed by the Virginia Uniform Statewide Building Code (USBC) based on the 2021 IRC and UPC. Local jurisdictions enforce these rules with variations in fees, timelines, and supplemental ordinances.
DPOR Licensing: Master, Journeyman & Gasfitter Requirements
Virginia requires plumbers to hold active DPOR licenses before performing regulated work. Master plumbers must complete 8,000 hours of supervised experience (including 4,000 as a journeyman), pass the PSI-administered master exam, and carry $50,000 in liability insurance. Journeyman plumbers need 4,000 documented hours under a master’s supervision and must pass the journeyman exam. Gasfitters require a separate DPOR license—either Class I (LP/natural gas distribution up to 2 psi) or Class II (all gas systems, including high-pressure)—with distinct experience and exam requirements. All licenses renew biennially on June 30, requiring continuing education: 8 hours for masters and journeymen (including 2 in USBC updates), and 16 hours for gasfitters. Unlicensed work is a Class 1 misdemeanor under § 54.1-1115 of the Code of Virginia, and local building officials may reject permits or issue stop-work orders for unlicensed activity. Contractors must verify license status via DPOR’s online licensee search before subcontracting plumbing work.
Permit Application Process & Jurisdictional Variations
Plumbing permits in Virginia are issued by local building departments—not DPOR—and applications must accompany detailed plans, manufacturer specs, and proof of licensure. Required documents include a completed application form, site plan, plumbing riser diagram, pipe sizing calculations, and signed affidavit confirming DPOR license validity. Fees vary by jurisdiction: Fairfax County charges $125–$475 depending on project scope; Richmond City uses a fee schedule tied to construction value (e.g., 0.12% of plumbing cost). Most localities require electronic submission via eTRAKiT or similar platforms. Notably, minor repairs (e.g., faucet replacement, unclogging) and residential lawn irrigation systems are exempt per USBC Section 105.2, but water heater replacements—even like-for-like—are not exempt and always require permits. Some counties, such as Loudoun, mandate pre-application meetings for commercial projects over $50,000. Applicants must designate a DPOR-licensed plumber as the responsible party on all submittals; failure to do so results in automatic rejection. Permit review timelines range from 5 business days (residential) to 20+ days (complex commercial), and expired permits lapse after 180 days without inspection.
Inspection Stages & Compliance Enforcement
Virginia mandates four mandatory plumbing inspections for most permitted projects: (1) Rough-in (after piping is installed but before wall/ceiling closure), (2) Drain, Waste & Vent (DWV) test (air/water pressure test per USBC Table 2903.2), (3) Final (post-fixtures, controls, and connections), and (4) Backflow prevention device installation (if applicable). Inspectors verify compliance with the 2021 USBC, referencing IPC Chapter 25 and UPC Chapter 6. Critical failures—such as unsupported piping, improper slope (<1/4" per foot for DWV), or lack of cleanouts—trigger written correction notices with 10-day resolution windows. Re-inspection fees apply after two failed attempts. Localities like Arlington County require digital photo logs uploaded to eTRAKiT prior to rough-in inspection. For gas systems, a separate gas pressure test (minimum 10 psi for 15 minutes, no drop) is required before final approval. Noncompliant work discovered post-occupancy may result in civil penalties up to $500 per violation under § 36-105.1, plus mandated system shutdown until corrected and re-inspected by the local building official.
Backflow Prevention & Water Heater Installation Rules
Virginia enforces strict backflow prevention under USBC Section 1612 and the Virginia Waterworks Regulations (12VAC5-610). All commercial buildings, multi-family dwellings ≥3 units, and facilities with fire sprinklers or irrigation systems must install ASSE 1013– or ASSE 1020–rated reduced pressure principle (RP) assemblies at the service entrance. Residential single-family homes require vacuum breakers on hose bibbs and anti-siphon fill valves on toilets, but RP devices are only mandated if cross-connection hazards exist (e.g., chemigation, boiler systems). All assemblies must be tested annually by a Virginia-certified backflow tester and reports filed with the local water authority. For water heaters, USBC Section 2904.3 requires temperature and pressure (T&P) relief valves rated for the heater’s max input, discharge piping of same diameter (min. 3/4"), terminating within 6" of floor level, and free of traps, valves, or tees. Electric heaters must have GFCI protection per NEC 422.13; gas units require combustion air provisions meeting IRC M1703 and seismic strapping in Zone 2+ areas per VA amendments to IRC P2803.1.1. Tankless units require dedicated 120V circuits and minimum 3/4" gas supply lines sized per NFPA 54.

Get VA Permit Guidance NowFrequently Asked Questions
Can a journeyman plumber pull a permit in their own name in Virginia?
No. Under DPOR regulations (18VAC35-22-40), only master plumbers may act as the 'responsible agent' on plumbing permits. A journeyman may perform work under a master’s supervision but cannot sign or submit permit applications independently. The master must be listed on all submissions and assume legal responsibility for code compliance.
Is a gasfitter license required to install a natural gas water heater in Virginia?
Yes. Installing any gas-fired appliance—including water heaters—requires either a Class II gasfitter license or supervision by one. A standard plumbing license does not authorize gas work. Violating this triggers enforcement under § 54.1-1115 and voids insurance coverage for related claims.
Do Virginia counties require backflow testing reports to be submitted directly to the building department?
Not uniformly—but many do. While state law mandates annual testing, localities like Henrico County and the City of Norfolk require certified testers to file reports electronically with the building department within 10 days of testing. Others, like Chesterfield, accept reports only from testers registered with their office. Always confirm submission protocols with the issuing jurisdiction before scheduling tests.
