I am wanting to turn this wall into a pony wall to open up my kitchen. It is directly under a truss. It contained a pocket door and there is no floor joist running under it or no other load bearing item in the basement under it. The top plate of the wall intersects the top plate of the exterior wall and is directly under the truss. The yellow circle is the truss and the red is the top plate of the interior wall interlcoking the exterior wall top plate.
What, if anything, can be done to safely remove the top plate of the wall? Can the 2x4 be cut flushed?
