Attached pic shows my rim joist underneath a door (where I'd like to attach ledger for deck). It's only under the door (around 5ft wide) and the deck ledger will be 14ft. It's bone dry, and there's another rim joist behind it (they're doubled up). Bought the house a year ago and tore out a concrete slab and step that was improperly flashed... that's what caused this. Assuming I flash the ledger correctly and this get no worse, can it be left as-is? Thanks!
