What requires a building permit in Prince William County?
Under the 2021 VUSBC and Prince William County Code, permits are required for all new construction, additions, installations, alterations/remodeling, demolition, changes of use/occupancy, movement of a lot/property line, asbestos work, and any work not specifically exempted:
Permit required
- New construction, additions, and alterations
- Structural modifications
- Reroofing, windows, siding changes
- Electrical, plumbing, and mechanical work
- Decks, pools, fences, and accessory structures
- Change of occupancy or use
- Demolition and asbestos removal
- Movement of a lot or property line
Typically exempt
- Painting, flooring, and cosmetic work
- Detached accessory structure ≤ 256 sq ft (may still need zoning permit)
- Retaining walls ≤ 4 ft
- Same-type fixture replacements
Exemptions are narrow and scope-specific. When unsure, confirm with the building department before starting — see the penalty note below.
Get the permit issued before starting work. Building without one exposes the owner to penalties and stop-work orders. Note that exemption from a building permit does not exempt a project from zoning requirements — confirm edge cases with the building department.

Verify your contractor's license. Virginia requires a state contractor license issued by the Virginia Department of Professional and Occupational Regulation (DPOR) for any project valued over $1,000. Licenses are classed by project value: Class A ($120,000+ per project), Class B ($10,000–$120,000), and Class C ($1,000–$10,000). Each class requires specific experience, education, and financial qualifications. Homeowners may perform work on their own primary residence without a contractor license, but all permits and inspections still apply. Verify licensure at dpor.virginia.gov.
