How do you tell if a wall is a load-bearing wall?

Step 1: Determine Whether a Wall Is Load-Bearing or Not

  1. Check an unfinished basement or attic to see which way the joists run.
  2. If the wall runs parallel to the joists, it’s probably not load-bearing.
  3. If it’s perpendicular, it most likely is a load-bearing wall.
