Do you need a special license to work as a contractor in Loudoun County or Ashburn?

No. Virginia issues contractor licenses at the state level through the Department of Professional and Occupational Regulation (DPOR), not by city or county. A contractor working in Ashburn, Leesburg, or anywhere in Loudoun County needs a Virginia state contractor license (Class A, B, or C) — the same license used statewide. Some localities require a separate business license (BPOL) to operate, but the contractor license itself is issued by DPOR.

Which Virginia contractor license class do I need in Loudoun County?

It depends on project size, not location. Class C covers single projects of $1,000–$29,999 (under $250,000/year). Class B covers $30,000–$149,999 per project ($250,000–$999,999/year). Class A has no monetary limit and is required for projects of $150,000 or more, or $1 million or more in annual gross receipts. Given Loudoun's large commercial and data-center projects, most contractors targeting that work pursue a Class A license.

How do I become an electrician in Ashburn, VA?

Electricians are licensed statewide through DPOR's Tradesman program. A Journeyman Electrician typically needs about 4 years and 8,000 hours of experience (or an approved apprenticeship) plus a passing score on the Virginia Journeyman Electrician exam. A Master Electrician needs at least one year of experience as a licensed Virginia Journeyman and must pass the Master exam. Both exams are administered by PSI and require a 70% passing score. Ashburn's data-center concentration makes licensed electricians especially in demand.

Q: What does a Virginia contractor license cost in 2026?

As of 2026, DPOR application fees are approximately $425 for Class A, $405 for Class B, and $260 for Class C, plus a technology fee of about $7.25 per year effective July 1, 2026. Additional costs include the 8-hour pre-license education course, PSI exam fees (Class A and B), and either net-worth documentation or a $50,000 surety bond. Always confirm current fees on the DPOR website before applying.

Q: How long does it take to get licensed?

Once you meet the experience requirement, most applicants complete the 8-hour pre-license course and exam prep within a few weeks, schedule the PSI exam, and submit the DPOR application. Processing typically takes several weeks after a passing exam and complete application. Exam preparation is the biggest variable — structured prep shortens it significantly.

THE SHORT ANSWER

What you need to work as a contractor in Loudoun County

To work as a contractor in Ashburn or anywhere in Loudoun County, you need a Virginia state contractor license issued by the Department of Professional and Occupational Regulation (DPOR) — Virginia does not issue licenses by city or county. You choose a class based on project size:

Class C — $1,000–$29,999 per project
Class B — $30,000–$149,999 per project
Class A — no limit; required at $150,000+ per project or $1M+/year

To qualify you'll need the required experience, an 8-hour pre-license course, and — for Class A and B — a passing score on the PSI Business & Law exam. Electricians are licensed separately through DPOR's Tradesman program as a Journeyman or Master Electrician.

Loudoun County local requirements: what to know before you bid

Your Virginia state license works statewide, but Loudoun runs its own local rules on top of it.

You'll need a Loudoun County business license (BPOL). On top of your state contractor license, you'll register for the county BPOL if you have a place of business here. Even out-of-state contractors may need one if they work in the county and top certain revenue thresholds.
Permits go through Loudoun County, not the state. Once licensed, you'll pull residential and commercial permits through Loudoun County Building & Development using its online system, LandMARC.
Plan reviews can be rigorous. The county often requires detailed review before issuing permits — especially for new homes, additions, decks, finished basements, commercial work, fuel gas, and environmentally sensitive sites. Zoning overlays, steep slopes, and well/septic can add documentation.
A building permit often isn't enough. Depending on the project, you may also need zoning approval, a grading permit, Health Department sign-off for well/septic, HOA approval, or approval from an incorporated town if the site sits within one. Identifying these is the contractor's responsibility.
Specialty trades need the right designation. Even as a Class A or B contractor, electrical, plumbing, HVAC, and other regulated trades must be done under the proper specialty classification and permits. As the GC on an addition, you'll still need licensed trade contractors for their portions.

What doesn't change: the state process. Complete your pre-license education, pass the required exams, meet the experience and financial requirements, and apply through Virginia DPOR.
