Builders put most of their effort on ensuring that the finishing looks good, so I would focus, personally, on ensuring that the concrete, framing and insulation are done right.

Pay Eddie $200 to do a framing inspection for you. (Just kidding.) I actually caught a major structural defect in the framing on my own house. If Eddie can't do it, maybe you can find an inspector who specializes in new houses.

I guarantee you the vapour barrier will not be done right, particularly on rim joists, where they typically only loosely staple it on. Don't believe me -- go down to your basement and check your own house. Get them to seal it properly (they are supposed to).

Lastly, please tell me you aren't getting stucco.

Above all, whatever stuff happens, try to keep a good relationship with the site guys. They are still the key to getting your home done right.
