The great thing about building is that you can have the repairman certificate to do the yearly conditional inspections yourself.
But even if you don't get the repairman certificate, you can still do all your own maintenance. You would just need an A&P to sign off the conditional inspection.
I do all my own maintenance and can sign off my conditional inspection, but being that I didn't build the engine, I usually pay the local A&P $200 to come over for the engine check while I am inspecting the rest of the plane.
When inspecting the wings there are only 6 inspection plates to remove from the bottom of the wing and then the wing root cover. Total time to R&R and inspect would only take one hour.
