Here are both the builder blue prints and foundation plans. According to the plans all external walls and garage are load bearing and internal walls are not. There is no built up foundation/headers internally, only thickened on external walls.
I want to completely take down the wall running horizontal from the garage to the kitchen which includes closet, kitchen wall, half walls (lv rm) and where pantry (no longer there) are indicated. Since the trusses run perpendicular and the middle of the truss (middle of the A) is where the wall is, my S/O is arguing it is load bearing. Full disclosure: I removed a quarter of that wall (next to the closet) more than 10 years ago based on these plans—no sagging to date.
