this is looking up the stairs. believe it or not the camera is held level.

[charlie_the_tuna]

this is looking down the basement stairs just under the other stairs.

if you look closely in the second picture you can see the stairs coming of the wall on the left side.

Are you sure the problem lies only with the lower joists?

I live in dryrot and termite heaven, usually the problems (at least around here) is a multiple thing.
House foundation settleing, sills seperating from the floor level, etc.
Have you poked around and made sure there aren't any other problems causing this?

I think you will be tearing into that wall on the right, You going to need to rebuild it and level it for new stairs. Foundation must be settling for some reason on that side?

[tsubaki]

Yeah, I can't make no sence of it not actually being there.
Look also if the walls seem to have gotten farther apart in some locations.
Don't be surprised if the house ain't square or level, few actually were (mine ain't, it was added on to in 1957)
Have someone help you (or drive a nail) pull a string tight from one end of the room to the other in every possible direction, measure or eyeball and see if the problem keeps showing up in the same place.
Normally you see this problem on exterior walls where the nails have rotted off, not on the interior side of the stairs
