We are finishing our basement stairs, and I'm struggling with how to drywall the side that is parallel to and tight against the foundation. Should I pull down the stairs, frame the wall, hang drywall, and put them back up? Or can I just frame against the foundation and stairs and let the drywall tie into the stairs? I don't care what it looks like below the stairs because it will be a cedar lined closet.

We also don't plan on framing a full wall here because the stairs are already narrow and we can't spare the space. We planned on using 1x2 stock attached to the foundation, and securing the drywall to that.

    A picture of the situation would help. In my jurisdiction you must install 1 hour firewall (Type X plasterboard or other suitable fire-resistant finish) under stairs if the space underneath is going to remain accessible... – Jimmy Fix-it Jul 14 '19 at 0:43

  • Good call on the fire rating, I'll put up a piece of type x before finishing it with cedar – Lee Harrison Jul 14 '19 at 0:58
  • Voting to close as primarily a matter of opinion. It comes down to prerogative and jobsite conditions which is preferable. – isherwood Dec 20 '19 at 15:12
  • If you push out the wall with your furring strips and drywall, will you still have the required 36" clear width? (How wide are your stairs currently?) – Huesmann Jun 25 '20 at 15:48
