I'm planning a deck for the back of my house that will be tucked into an inside corner of the building. I'm not sure how I'll attach the outer joist to the ledger board, since that will be tucked right up to the corner on the foundation, so I wouldn't be able to drive nails in from the left side:
The only things I can find by Google search suggest things like a corner bracket:
I don't see a specific line in IRC that prohibits this, but I note that the
AWC Prescriptive Residential Wood Deck Construction Guide states "Use joist hangers with inside flanges when clearances to the edge of the beam or ledger board dictate. Do not use clip angles or brackets to support joists."
I can't believe that this is an unusual problem, so there must be a standard way of addressing it, right? The best I can figure is to attach this joist (and one at the other side with the same issue) with a hidden-flange hanger before I anchor the ledger, but this seems cumbersome. My locality requires three inspections, the first of which happens after the ledger is attached and footings are dug, but before concrete is poured, which means that during all the foundational work, I'd have these joists hanging out in the breeze for me to trip over and/or break while I'm working.
What do I do here?

When I built my deck I used a the same joist hanger as the rest of the joists but moved it and the joist inward the thickness of the joist. Then nailed/screwed an additional joist to its face to even it up to the edge of the ledger. This worked well because it gave me twice the thickness to secure the planks and kept the nails/screws away from the edge. The additional piece could be raised to the height of the planks it you wanted to frame in the planks.
