OSB over uneven framing...
 
I'm walling off a carport that is framed, but is far from being plumb or square. What is the best approach to properly aligning OSB sheathing in this case? The floor and ceiling lines are not parallel, which is compounded by a slight bowing of the concrete slab/floor. Also, the outer corners of the walls are not square at all.

Given that, is there a particular edge I should be aligning my OSB against, or any recommended approach to dealing with these imprecise dimensions?

Why not move each stud over to plumb?

Actually, most of the studs are fairly new and are plumb. My bigger concern is dealing with the outer corners of the structure, which are not (and I'm guessing short of rebuilding, there isn't a lot I can do to adjust what is there). Then again, I don't have any experience with this and imagine there are things that I'm just not thinking about.

Since there's no sheething on the walls... every wall can be plumbed..straitened and braced. Not following why you can't plumb the outside corners.

The corners can be furred out/in with tapered shims to make them plumb.

So, my fault for not giving you guys all the info - the carport is actually walled on the back and one side with concrete blocks stacked about 3 1/2 to 4 feet up (on top of a concrete slab). And then there is framing above that. I think the problem is that the ground has settled and the concrete blocks are now no longer plumb. The third "non-entry" wall has steel post supports, with newer framing in between them.

Honestly, this whole carport is a train wreck, but I want to do the best I can with what I've got for now. Long term it will probably be coming down at some point (either to rebuild or to use as yard space).

Wilco, if this is a short term fix as you mentioned, and the studs are plumb: start off a stud and work towards the corner letting the osb run long.
Then run down the corner edge with a saw or sawzall cutting off the excess.

Typed that last post from my cell phone. Can just about see the the letters ....didn't check the spelling. I meant straiten the wall. Thought this was new framing.
