Very nice. I appreciate the through-wall mounting too. I start and finish stuff before the permit is issued all the time too. It shows both your confidence in your design and understanding of the code, LL requirements, etc. It also shows that you are charging enough to do the job (cause your cost to do it should have only been a small part of what the customer pays anyway and was likely much less than the deposit that was already left). That's my thought on it anyway. Excellent job Bob!
