I need to hang a 22' ledger board, but I can only get treated boards up to 20' in length. The deck plan calls for a doubled joist at the 18' mark, which is where the edge of the main body of the deck meets the upper stair landing (a 4x4 landing). So it's a doubled rim, and the seam to the landing at the same time, I suppose.
So, the problem is that I need to split the ledger into two boards and I'm trying to figure out the best place to do it.
To further complicate things, the ledger is being hung on a brick veneer wall, so I plan to use these Simpson BVLZ connectors to do it. Since I am going to have joists 12" OC, that leaves very little room in each joist cavity in which to place this ledger joint.
My thought is to split the ledger into a 4' board and an 18' foot board so that the split sits at the double joist I mentioned earlier. But that means I either have to do it using two concealed single hangers sitting side-by-side, or use a double hanger that would be attached across the seam.
Is either one of these options allowable? Preferable? Is there another way I'm not thinking of?
P.S.: just after posting this it occurred to me that since there will actually be two posts under the stair landing (only one is shown in the image), that part of the ledger should carry minimal weight, meaning I could eliminate one BVLZ to free up a joist bay in which to place the seam. That means one very large and one very tiny ledger board, I suppose. Thoughts on this additional consideration?
