Contractor License for Flippers in VA

[Evan J.]

If a firm is engaged in rehab and resale of residential properties in Virginia and performs the work using it's own employees instead of employing a third-party GC, is that firm required to maintain a contractor's license?

Provided that the work is done to code, of course.  Owner-developers are exempt from licensure in some cases--I'm wondering if that applies to flipping.
