In my addition, I did all the wiring myself. I found when dealing with the inspector, neatness was the easiest way to impress him. Having everything looking nice and easy for him to figure out saved me lots of rework, I believe. He did have a few things for me to change which were painless. He also found things that I did that were not typically how a pro would do it, but the only harm was to the budget. He also said he had never seen so much LV wire run, but I got that disease after discovering CT.
