Any evidence that there was ever support under the chimney?

When we bought our place we had 2 chimneys similar to that. They built a knee wall about 4' from the floor. They bricked the chimney, 1 course on the knee wall then 2 wide, etc. until they had a square chimney out the roof. They also knocked the brick down just below the roof when they abandoned them rather than take them out completely. One was in a small room so the floor joists didn't have a very long span. But, the living living room span was longer and over time the floor had about a 2" sag from the unsupported weight. It was in a wall that was coming out anyway, so I removed the wall and all the floor boards down the the floor joists. Then I shot a grade and 1 by one jacked them back in place. A few were so bad the best I could do was get them close and then sister new joists along side them to get everything level. It's an oak hardwood floor now and still is level & no squeaky boards, but it was a lot of work to get it back in shape. Hopefully yours goes easier that mine.

From the attic I can look down between the apartments and see a void between the chimney and floor joist support beam large enough to walk through. Who does stupid stuff like this. I don't know everything but I have never seen a chimney supported by the house. I have three and the house is sinking.

Maybe somebody has some input or ideas. I have a couple of ideas but wow this is going to be a major project.

Thanks for any input.
depends on the chimney, if it is a wooden structure, then it can sit on the concrete with out a footer.

if it is a masonry chimney it requires a substantial foundation

or beams to hold the weight

It almost looks like it was built to support the roof.
