I'm sure others here will disagree with me but a home inspection is not technically exhaustive. What you are doing is crunching numbers.... I assume you're also crunching all of the calculations for floor loads and roof loads, measuring all of footings to ensure proper size given the loads you come up with, etc., etc.

I'm not trying to give you a hard time.... but, personally, I don't go down the code road nearly this far.... ever.
