The ceiling above the stairs in my house (1950s, Minnesota) is too low.
I want to remove the offending joist (the one that's vertical in the picture), cut back the adjacent joists (horizontal) a few inches, then move the joist over and reinstall it.
The stairs go up to the right of the picture. The wall on the left is exterior, as is the wall in the background (obviously, since it has a window).
If I do this work without putting up structural supports, just letting the studs "float" for the hour or two while I reinstall the beam, will the ceiling fall on my head?
Edit: The floor above is a walk-in closet. Directly above the double joist is the front edge of the "box" that forms the bottom of this little shelving alcove in the closet. The floor above that is the attic which is unused/unfinished, just insulation, and is accessed through a trapdoor on the opposite side of the house.
