There is one house that I am inspecting right now and the house was under construction for 3 years now and it is still not ready for a final inspection. The house has 600 amp service, 7-9 sub panels, (I can't remeber how many, I haven't been there for a while. Indoor swimming pool, indoor waterfall, which will empty into an indoor fish pond. Stand by generator, 6-9 HVAC units, inculding 3 for the pool area. It has it's own elevator, beauty salon, 6 car garage. Plus a few more items that I can't remember, like a hidden room behind a book case. (I think)
