Building New Partition Walls

[olds]

@Greenman ET AL

When building partition walls in an already finished space, do you butt the top plate up to the sheetrock on the ceilings and walls and nail through the sheetrock, or cut a space in the sheetrock and butt up to the original framing?
TIA

Depending on whether the new partition lines up to existing 2x4. If it lines up just nail through tape. Use a spacer (drywall height) just to be safe. If it doesn't line up then you will need to add a cross member from top and bottom and depends on access to space above and behind existing wall.

As long as there is something in the ceiling to anchor to, you can go right over the existing drywall. If you end up running parallel between the existing ceiling joist, you need to add some backing to connect the top plate to.

This is in a basement.
My plan is to line the new wall up with an existing stud in the wall and joist in the ceiling.
There will be another wall at a 90, it will cross the joists and will attach to the foundation wall.

Thanks

Upgrading the basement. That should make a lot of people happy.
