Notice these vertical joist supports for this single story bedroom addition built in the late 90’s. There is concrete below, not much, appears to be spillover from the stem wall pour, the 2x’s are shot into the stem wall with a powder fastener, and H clips placed at the top. The 4x beams above do not index into a pocket in the wall, they simply abut it. Joists above the beam run perpendicular. Sure looks problematic to me. Looking for feedback as I finish up the report.
