It took a while but I finally figured out what has been bothering me about the inside build. Before going into IT when I got out of the Army, I worked as an electrician's assistant while I was in school. Watching today It finally hit me, he is pulling 12/2 and 14/3 for plugs lights and switches which are correct but he's skinning the sheaths and making up the joints before he has drywall up. This is a no no. You leave the Romex sheath on until after drywall because:
a) Drywall compound is wet and its will be getting inside your boxes.
b) It protects the wiring when you cut your box openings.
c) You want to minimize your chance of hitting live wiring. (esp. with a toddler in the area)
Plugs and switches are supposed to be installed after drywall and paint and while I can see why he would install one or two circuits before drywall it appears that he is making up all the joints pre drywall. While it probably wont cause him much of an issue and he doesn't have to worry with code enforcement he should still stick with codes and industry accepted practices because they exist for a reason. Usually to keep you from harming yourself or others.
His using a 21" on center stud spacing is also a bit troubling as 18" on center is pretty much standard in the US.
