does subfloor removal affect structure?
The plan is to level the first floor of this 1-1/2 story wood frame house by pulling up the subloor and sistering new level joists to the original 2x6s.
I’ve started to pull up the subfloor and want to get some expert opinions before I go too far. Do I need to be concerned about the structure of the house if I pull up the subfloor? It doesn’t seem like the subfloor would affect the structure. I’ve jacked in a few areas but the floor is still off here and there.

Thats interesting. I was going to say you'd have a problem under walls, but it appears that the sub floor doesn't run under the toe plates. If not, you are golden!
The posts may be an issue, but it looks pretty straightforward, IMHO. Of couse, I am not an engineer!

No structural problem.
I can only see so much in phortos, and you probably do need to sister to get strength, but I would probably get level by jacking thiose timbers from under

If I jack the timbers and add the sisters, what if the joists lift off of the sill? I am trying to avoid jacking the sill. Can I block if I get gap?
Thanks guys. I went over this morning and took another look. I'm going to take it slow. I think looking at the place taken down to the skeleton throws me. I've lifted in a couple of places already. Lifted the front 4 or so inches a couple years ago. Replaced a post in the basement under the midspan. Put up a lvl midspan on the first floor. Trying to finish the structural work so I can move on, but I've got this weird thing that doesn't let me half-####... If I can get the floor feeling solid, non-bouncy and looking level, i'd be giddy. Level is a subjective idea, right? ;-)It's not like being there, but here are a couple more pictures. Some day I'll have read all of George Nash's book. "The renovation of old houses is more than an investment, more than a handyman's challenge or a shortcut to home ownership," he writes. "It is a spiritual undertaking as well."

Roar! You can certainly tell he'd been there!

Thanks! Now we just need somebody in worse shape than you and both of us will be feeling better.
Looks like you have things pretty well in hand.One suggestion though.
Where the joists are notched into the sills - get some full size joist hanges to add at that connection. That way you will have full bearing connection ibnstead of using only half the strength in the joist. if the joist is splitting already, use a jack under it or a bar clamp to sinch it up tight to itself eliminating the check or split be3fore setting each joist hanger. maybe even sque3eze a little PL into the split first. Then hang the hanger and a lot of sag and bounce will go away, and if you still feel the need to sister, it wil have some thing to hold onto.

BTW, Nash is good, and so is that light string. I have two of them. One of Nash
