I would very politly flip out if i had pulled the permit or already delt with inspection.What about the final?If you have a good relationship with the inspector he may not look at it very closely so you had better.Anything not up to code would be fixed at the contractors expence including my inspection and any lip or dirty look would result in an instant rat out.I probably wouldn't involve the customer other than inform them that the bill will read completed by others and he would be initaling it to that effect.If the place burns down it's on you so CYA.Regardless i would still pick it apart simply because i like to sleep at night.
