Interior wall construction?
Im planning on taking in a corner of my finished out garage by adding two non load-bearing walls.

I wont have a problem anchoring my bottom plate to the concrete floor but I'm running into an issue on the celling. It appears as though the previous owner finished the garage ceiling with 2 layers of drywall (don't know why), this coupled with sprayed insulation in the attic is making it very difficult to locate the joists (even with my stud finder).

My question is this: is it absolutely imperative that I secure my top plate to the ceiling? Could i get away with anchoring just the bottom plate and then secure the end studs in my new wall to studs in the perpendicular walls?

I'd really like to not rip out all the drywall in the ceiling, do i have any other options?


PS: I'm new here, thanks for any help.

If you are doing it your self then you should first concern your friend or family member who is in construction business. if you will not take any advice and you will do it your self if some thing goes wrong the consequences will be disastrous.

It need to be attached. Is there any access to the "attic" area?
It would suck to have to to it this way but if you had to as a last resort you mark out where the top plates going and just drill a row of hole 1" apart until you hit the joist. Once you find one measure off 24" and see if there's another one. Once you figure out the pattern you can mark the top plate or mark the ceiling with dabs of blue tape.

It's not hard finding the joists. Holes can be repaired or lay out the room on the ceiling and put the screws through where the plate will lie.

I don't like the wall on the sheetrock idea because banging door will move the wall with joint cracks and wall with vibrate.

if the garage is attached its required by code to either use 2 layers of 1/2" drywall or a single layer of 5/8 board . its for fire code.
