How did you attach or support the floor joists at the new sill beam?
I can't figure out for sure the beams under the stairs. If they are below the floor joists, they may have been put there to support the stairs and wall beside the stairs just to take the bounce out of the floor.
floor joists just rest on the sill beam. I did add some L brackets but the original joists just sat on the sill between the wall plate and the sill.

So the floor joists are not long enough to sit the new sill and you are jacking up floor joists one at a time while sistering in new 2x10? I would not do this. You should be jacking up as many floor joist at one time as possible. A 4x4 makes for a good temp beam should be safe spanning 6'. Use 6x6 if lifting more than floor joists. You should not be jacking up the walls steps 2nd floor or roof unless there is obvious gap that needs to be filled. I see your wall has new studs so that would suggest that they were installed after the floor sank. I would not jacking anymore. Instead I would cut down studs of wall. you dont want to jack up 2nd floor if it doesnt need it.
The floor is out of level because a portion (first pic ) of the sill beam collapsed where the joist dropped with it in that area. The contractors fix was not raising the joists back up to the original position ,he just nailed a 2x4 to the side of the old one that attached to the top portion of the old 2x10 .So basicallly the 2x10 is still dropping below the sill beam while the new 2x4 is sitting on the sill beam just holding the original from falling more.However the original 2x10 supposed to be sitting on the sill also is supposed to support the wall plate which now nothing is. The problem is just in that 6' or so area however since he didnt fix that area he hacked up the rest of the kitchen joists to make it more level with the damaged area instead of fixing the actual problem then kitchen joists would have been good and level. Before he started on the house there was only a single 2x10 every 16oc .Now there 4 or 5 pieces of wood in all different spots off each original 2x10 making spots of unlevelness and voids all over.
The joists were long enough to reach even the new sill but the contractor cut them short because he didnt own a jack to get them back up wjere they were supposed to be before putting in the new sill beam.
I was able to get the joist under the stairs jaacked all the way back up yesterday so now the top of the 2x10 is up against the wall plate and bottom over the sill. I then sistered a new joist in there so it sits flat on the sill beam. now its in the same position again like when the house was built. It doesnt look like the jacking effected any walls,just the joist im thinking .There was very little pressure on the jack handles. The wall with the gap was put in after the problem and the contractor never even screwed it down to the joist . The whole bottom was pretty much floating. Well he had ply wood under it ,The plywood was touching the adjacent joists but not the joist under the wall which is the reason why the gap is there when the ply was removed.
I would like to here how you guys would do this job. Thats the reason im here. Anything im doing wrong or could be done better i would like to know. Im all about wanting to do everything right.
