Still working on a deck rehabilitation, and I ran into another interesting problem. When building the deck, rather than trimming the siding corner cap, some genius decided to simply build around it. They stopped the ledger short of the corner cap, nailed in an extension piece to the face of the ledger, then nailed the rim joist into the end of the extension piece.
The framing in the corner of deck looks like this.
To make matter worse. There's a single step attached to the rim joist, which is unsupported (sank into the ground). Every time somebody steps on the step, it yanks on the rim joist. This has caused the rim joist to begin to be pulled away from extension piece (since it's nailed into the end grain of the piece).
I'm obviously going to fix the sinking step issue, but I'd like to find a better way to attach the rim joist as well.
I was thinking of installing a 90° strongtie on the inside corner of the joint. Unfortunately, I can't get a driver in to drive screws (don't want to use nails into the rim joist, because that wouldn't be any stronger than what's already there).
The other thought was to put a 90° bracket on the top of the extension and rim joist. The problem there, is that it would be in the way when attaching my decking boards.
What should I do to make this connection stronger?

Try 2 Simpson HTT4s. The clip is screwed to the short ledger and long carriage bolts are drilled through the joists to draw back the floppy rim joist. Long bolts with washers will hold better too in my opinion, but may not look as neat.
