Bolt Placement on monolithic slab with brick face
I am planning an addition with a monolithic slab with a brick ledge for a brick facing on the exposed part of the footing/slab, with cedar siding on the rest of the wall that laps over the top of the brick to make the transition. My question is where to place the J bolts for the sill plate? Do they just go in closer to the edge of the slab and the sill plate span the joint on the brick and the slab? I have done a lot of searching, but I can’t seem to find a good answer to this question.

They go the same distance in from the edge of the slab no matter where the slab is. For a 2 x 4" wall that would be 1 3/4" from the outside edge of the slab.
Thanks for the reply. That certainly seems the strongest option. I did just find this old posting that describes better what I am trying to do. I intend to use 2x6 exterior walls.

I didn't understand that the brick is going to stop flush with the floor in which case the detail in the linked article is correct. FYI, no one uses J bolts anymore. We use wedge bolts that we drill in after the floor is poured. If you lay out your plates and drill the holes in the concrete while the concrete is green the holes go quickly.
Not sure how that will work as you are limited by the dimension remaining from the brick. If you use a standard brick, 3 5/8", then you have approx. 2" left for your bolt, and that's IF you form the ledge perfectly. I assume that you are not going to use the configuration in the link, as this will result in a stepped base on your interior. I would agree with drilling holes early on in green concrete, but I might think about letting the slab cure a bit prior to using a wedge-type anchor, as it could possibly cause some blow-out at the edge. Strategically placed box ties would help to lessen this. You might consider some type of epoxy system, depending upon your budget. The link depicts typical construction for a garage-type build, where the interior step at the sill plate really doesn't matter if seen.
Thanks for the help.
