Re: Support Wall
You're going the wrong direction. Start by looking under the wall to see if it is supported or just setting on the floor, that is a much better indication that it is or is not a support wall. Then check at the top of the wall to see if the second floor joists run across this wall or are two piece ending on the top of the wall. And no a support wall does not have to continue up through the second floor.
