How to Start a Plumbing Business in Virginia: Master Plumber Qualifier, $150 License, Residential Tier

October 29, 2026

Starting a plumbing business in Virginia means holding two different licenses, plus a business entity and a local tax license. Your personal tradesman license lets you do plumbing work for pay. A plumbing contractor license (PLB) lets a business contract for that work, and the business must name a master plumber as its qualifier. This guide follows the order you should handle these steps.

This article is general information, not legal or tax advice. Fees, classes and deadlines change, so confirm each figure with the agency named before you file or pay. For complex situations, consult a qualified Virginia attorney and a CPA.

What You Need Before You Start

Gather these items before you open any application. Most of them feed more than one filing.

• Identification and contact information for yourself and any co-owners
• Written proof of training and experience: diplomas, transcripts, and signed employer letters showing dates, hours and the work performed
• Your proposed business name, checked in SCC business records at cis.scc.virginia.gov
• A budget for each fee in this guide, including the $150 tradesman license, exam fees, and your entity filing fee
• A Virginia registered agent who meets the requirements in Step 5
• Insurance quotes, including workers' compensation if you expect three or more employees

Step 1: Understand the Two-License Structure

Virginia separates the person from the business. Most new owners get the qualifier wrong first, so learn these three rules before anything else.

• Tradesman license. Required for plumbing work performed for compensation, with no dollar threshold. Work done under a licensed plumber's supervision does not need its own tradesman license. The license is personal and does not transfer to your company.
• Master plumber. The higher personal license that qualifies you to serve as the qualifier for a contractor business.
• Plumbing contractor (PLB). The business license issued through the Department of Professional and Occupational Regulation (DPOR). It must name a master plumber as qualifier at every class, including Class C. A journeyman or residential plumber cannot serve as qualifier unless DPOR confirms otherwise.

If your company will sign contracts, you need a master plumber as qualifier. If you plan to hire installers, each one needs a tradesman license unless they work under a licensed plumber's supervision.

Step 2: Choose Your Tradesman Path

Your path depends on your education and training. Each row below is a combination of training and experience that qualifies you. Confirm with DPOR how it counts qualifying training before you rely on a row.

General journeyman paths

Education or training	Years of experience
Bachelor's degree in a related engineering curriculum	1
Associate degree or two-year certificate	2
240 training hours	4
160 training hours	5
80 training hours	6
40 training hours	7
No formal training	8

Residential plumber tradesman paths (effective 2025-04-01)

Training hours	Years of experience
160 training hours	2
120 training hours	3
80 training hours	4
40 training hours	5
No formal training	6

Check with DPOR for the scope of work a residential licensee may perform, and do not assume it matches a journeyman's scope. Gas fitting and backflow work each require separate certifications.

Step 3: Apply, Pass the Exam and Pay the Fees

Submit your tradesman application to DPOR with your training and experience records. The license fee is $150. Renewal costs $160 every 3 years, and you must complete 3 hours of continuing education for each designation you hold at each renewal.

Exam fees are set by the testing vendor, with caps of $200 and $225 depending on the exam. Confirm the exact amount and scheduling steps with DPOR and the vendor before you pay. This guide does not describe exam format, length or passing standards, so check those with the vendor as well.

Step 4: Earn Your Master Plumber License

You can qualify for the master license in any one of three ways:

1. One year as a licensed journeyman
2. Three years as a residential plumber tradesman
3. Nine years of practical experience

Keep dated employer records from the start. DPOR will want employers, dates and descriptions of the work, and those records are hard to rebuild years later. This guide does not list the master license fee, so confirm it with DPOR.

Step 5: Form Your Entity and Protect the Name

Form the business with the State Corporation Commission (SCC). The SCC forms entities but issues no business license.

Name rules. An LLC name must contain “limited company,” “limited liability company,” “LC,” “L.C.,” “LLC” or “L.L.C.” and must be distinguishable from names already on file. You can reserve a name for $10 for 120 days, and the reservation is renewable in the 45 days before it expires.

LLC. File Articles of Organization (Form LLC1011) for $100 through the SCC Clerk's Information System at cis.scc.virginia.gov. Virginia LLCs file no annual report. Instead, they pay a $50 annual registration fee, due the last day of the 12th month after the month the LLC was organized, and every year after that. The SCC assesses the fee about two months ahead. A late payment adds a $25 penalty, and the LLC is canceled at the end of the third month after the due date.

Online filings can be expedited: next day for $50 or $100 (submitted by 2:00 PM Eastern, response by 4:00 PM the next business day), or same day for $200 (submitted by 10:00 AM Eastern, response by 4:00 PM). Expedited service is online only and nonrefundable.

Corporation. File Articles of Incorporation (Form SCC619) for $75. A corporation's annual report and registration fee depends on authorized shares: $100 for up to 5,000 shares, plus $30 for each additional 5,000 shares. Check the SCC annual fee schedule for current figures. The annual registration fee is due the last day of the formation month. The annual report is due the last day of the 12th month after formation and may be filed no earlier than three months before that date.

Registered agent. A Virginia entity must keep a registered agent who is a Virginia resident with a Virginia street registered office, available during business hours. The agent must be a member of the Virginia State Bar, or a member, manager, officer, trustee or general partner of the entity. An entity cannot be its own agent.

Assumed name (DBA). If you will operate under a name other than your entity's legal name, file an Assumed Name Certificate with the SCC for $10. Do not file it with the circuit court. No newspaper publication is required.

Step 6: Apply for the Plumbing Contractor (PLB) License

A PLB covers piping, fixtures, appliances and appurtenances for water supply and drainage, hot water heaters, boilers, hydronic and steam heating, backflow devices, and related venting (18VAC50-22-20). Your business applies to DPOR and names its master plumber qualifier.

Class	Contract size	Initial fee
Class C	One contract over $1,000 but under $30,000, or under $250,000 in 12 months	$235
Class B	$30,000 to under $150,000, or $250,000 to under $1 million	$380
Class A	$150,000 or more, or $1 million or more	$400 plus $25 Recovery Fund

The class structure comes from the 2025 law, so confirm its effective date with DPOR. Also confirm how the single-contract and 12-month figures apply to your business, and whether the $25 Recovery Fund applies to classes other than Class A.

The contractor application also involves experience, net worth and a 6-hour business course. Review DPOR's contractor license requirements before you apply, because those rules are separate from the tradesman rules.

Step 7: Cover Insurance and Workers' Compensation

Workers' compensation is required once three or more employees are regularly in service (Va. Code 65.2-101). Failing to carry it can bring a civil penalty of up to $250 per day, to a maximum of $50,000 (Va. Code 65.2-805).

Workers' compensation is separate from general liability insurance. Many customers, property managers and general contractors will still ask for a certificate of liability coverage before they hire you. Get quotes before you bid, and ask whether the policy covers work in other localities. Premiums vary widely with payroll, claims history and type of work, so this guide does not list them.

Step 8: Obtain Your Local BPOL License

Virginia has no general statewide business license. The Business, Professional and Occupational License (BPOL) is a local license tax under Va. Code 58.1-3700 et seq. Each city or county administers its own, usually through the Commissioner of the Revenue. Localities set their own rates and filing deadlines.

Not every locality levies a general BPOL. Va. Code 58.1-3704 lets a locality levy none. Stafford, Rockingham, Bedford County, Washington County, Montgomery County, Louisa and Fluvanna are examples of localities without a general county license, and towns can take the place of the county tax within their limits. Check your locality before assuming you owe one.

Population limits what a locality can require:

• Localities over 50,000 people cannot require a license for gross receipts under $100,000.
• Localities with 25,000 to 50,000 people cannot require one for gross receipts under $50,000.
• Localities under 25,000 people have no statutory floor.
• Localities over 50,000 may waive the license for gross receipts up to $200,000. Verify this ceiling with your locality.

The contracting BPOL rate is capped at 16 cents per $100 of gross receipts (Va. Code 58.1-3706). That is a ceiling, not your city's rate, so confirm the actual rate with the local office. A plumbing contractor is taxed by its home locality. Another locality may require a license only after $25,000 of work there in a year (Va. Code 58.1-3715).

Step 9: Register for Taxes and Plan Payroll

Register with Virginia Tax if you will charge sales tax or have employees. The statewide sales tax is 5.3% (state plus local). It rises to 6% in regional-tax localities, 6.3% in eight localities, and 7% in the Historic Triangle (James City County, Williamsburg and York County). Groceries are taxed at 1%. Ask Virginia Tax whether any part of your invoices, including materials you sell, is taxable before you set prices.

Corporations pay a 6% flat corporate income tax. Owners of pass-through entities, which include many LLCs, generally report business income on a personal return, where Virginia's personal rates run from 2% to 5.75%. Ask a CPA how your entity is taxed federally and in Virginia.

If you hire, Virginia's minimum wage is $12.77 in 2026, $13.75 in 2027 and $15.00 in 2028. Build those figures into your labor costs now.

Common Mistakes to Avoid

• Naming a journeyman or residential plumber as the contractor qualifier. The qualifier must be a master plumber at every class.
• Treating the tradesman license as the business license. The tradesman license is personal. The PLB is the contractor license, and the local BPOL is separate.
• Filing the DBA with the circuit court. Virginia uses the SCC for Assumed Name Certificates at $10.
• Missing the LLC annual registration deadline. A late $50 payment adds a $25 penalty, and the LLC can be canceled.
• Choosing a class from one job's size. Classes depend on contract size and 12-month volume, so plan your annual bidding before you apply.
• Assuming the local license is the same everywhere. Some localities levy none, and rates and deadlines differ.
• Assuming residential scope equals full scope. Ask DPOR before accepting work the residential tier may not cover.
• Letting continuing education lapse. Renewal requires 3 hours of continuing education for each designation.

Expected Results

Following these steps in order may help you move from individual licensing to a business that can bid and contract for plumbing work in Virginia. Your timeline depends on how much qualifying experience you already have, which tradesman path you use, and how quickly each agency processes your filings. Readers who already hold the required records often move faster than those who must document years of work first. Treat this guide as a roadmap, and check every figure with the agency that controls it.
