I'm finishing my basement, and am framing in a room. I have 81.5" of ceiling clearance to the ceiling joists, and am in the process of framing in a door for a bedroom. My question is, since this wall is not load bearing, is it required to have double studs, as there's no structural header to hold up. In this case, due to clearance issues, the header is also the top-plate of the wall.
I've attached a rough picture to give you an idea of what I'm planning on doing.
As you can see, the top plate extends the full length of the wall. There is no room to install an additional plate as a header, the top plate will serve this function. Since there's no normal header to hold up, is a jack stud needed, or no? Is it ideal to provide support in the wall, or just not necessary?
