non load bearing wall fasten to a sister board?

In my basement I need to build a wall in parallel to a floor joist above. the wall is non load bearing, but lands between two joists. I found it is very close, and if I add a sister board next to the floor joist above, it will screw into that very nicely. Is this allowed, or do I need to install blocking every 16" on center between two floor joists? most times I wouldn't have a problem with it, but its an exterior wall, so in order to do that, I would need to remove some of the spray foam up there which I would rather not touch lol.

You also usually need drywall backing if you are hanging sheetrock on the ceiling, so you either want to lay a 2x6 flat on top of your top plate and fasten that to the joist, or put in perpendicular blocking every 16 - 24" or so.

Thanks! My current plan is to take down the existing drywall, install the sister boards, then re-hang the drywall. Then fasten the top plate to the sister board. That way the drywall creates the fire blocking above the top plate. Hopefully that works?

It works if you don't have any electrical to do.

Can you tell me more about the electrical? So if I need electric in the wall I canít put it below the drywall? Sorry for my confusion, this is new to me so I want to do it right.

The electrician will be pretty upset if you put up drywall before he roughs in the wiring.

Lol yes, I could bet! I was thinking once the wall is fully framed I could use an ocelating tool to cut a nice straight edge along the front of the wall, then take Sheetrock back off the ceiling for hvac and electric.
