Floor framing with a ledger

Thanks for the idea with the 2X8's. I actually had someone else mention that to me as well, but instead of using top-flange hangers, just bring the ledger up flush to the top of the 2X8 and use standard hangers. (that's not a problem with code, is it?) If they both work, I'm not sure which one would be preferable. Would that present a problem with door openings? It would be nice to have the thresholds attach directly to the concrete instead of putting flashings over the subfloor...

If you raise the ledger, the bolts through the ledger probably will be going into the concrete pretty close (too close?) to the top edge of the concrete, especially if you use a staggered pattern. I don't know why you'd want to spend the extra labor and materials for the ledger just to avoid top flange hangers, but that's your call, of course.
