Sorry if my terminology is bad, I tried to pick up some of the terms and do some research in the ICC before posing the question here.
I've got a contractor replacing a deck for me and I noticed that he attached the joists to the ledger, then removed the screws and (looks like) pulled out a corner of the frame. This now caused a gap to gradually increase in distance from the ledger to the point where some of the boards now terminate in the hanger just before the hangers can screw into the board.
I understand that the best support for the joists, the wood should be fit as far in as possible. Is this an allowable gap? What should I expect to see in a fix of this is out of code?
