Thing is, there really aren't any enforcers. There are inspectors, but they don't judge until you're done. Waste of time, otherwise. No matter what they'd say, you'd say "I know, I'm getting to it! I'm not done yet! Get out of here!"
A lot of what would appear to be questionable carpentry/construction practices are temporary moves. Braces, shims, sheathing, etc. are all used to get things into place and hold them while you do something else meant to be proper and permanent. Interim moves, if you will. An enforcer would go nuts on all that stuff. So, they don't bother. Inspectors let you have all the fun you want, then come in when you're done and tell you to tear it all down or you're gonna get fined 80 bajillion dollars a day for maintaining an attractive nuisance or public endangerment or something.
Not that that's what's happening here. This guy is clearly bonked in the head and way out of his depth. If you didn't know any better, you'd swear it was a comedy routine.
