I'm building a (low) deck, and the siding is brick. I don't think attaching ledger board to brick siding is a good idea, it's not structural, even if I drill all the way through the brick, air gap and into the rim joist, the load will be on the brick, plus water penetration issues.
The distance from top of foundation to top of door threshold is exactly 12", so I was thinking 2x10 joists plus decking will bring the deck surface almost level with the indoor floor level.
I know I can build a freestanding deck, but I don't want to pour more footings than absolutely necessary. I'm in Ontario, so these have to be rather deep.
