We are looking to add a door to a wall in our basement and wanted to see what was possible by figuring out what wall is the load bearing wall. Both walls are perpendicular to the joists. The wall on the right in the first pic extends the length of the house and is nearly dead in the center of the house. I would assume this is load bearing?
The second wall and the wall we want to put a door into only runs about 2/3rds of the length of the basement and is not centered.
The ceilings are short down there and there are not room for a beam to cover the spans where the wall isn't on the photo above. Am I right to think that this wall is not supporting our house?
