I'm building an enclosed 1 floor addition on the side of our house which will extend our side entry to become a mudroom and provide for a pantry off our kitchen. We need the space under the addition to be open for various reasons, so are using a post foundation and ideally a ledger board against the existing house. i.e., the framing will be constructed similar to an attached deck.

Our house was built in the 40s and is 2 wythe brick and block solid masonry top to bottom. So its brick on the outside, CMU on the inside, tied together with header blocks every 7th row. This is NOT brick veneer on wood construction.

I'm getting this permitted. I can't seem to find guidance on how to attach the ledger board in a way that complies with 2018 Virginia Residential Code, which is based on the 2018 International Residential Code. I do see how to attach the board to CMU. Can the same apply to brick and block? If not, does anyone no a code compliant way to do this using a ledger board?
