Could second floor be unleveled?

Question

I live on the second floor and I want replace the carpet with wood or tile. A friend told me if the floor is not leveled, it cost a lot to level it. My question is: Could second floor be unleveled? I thought only first floors could be unleveled.

Answer 1

Second story floors can be and often are out of level. Even more important than levelness, though, is flatness. It is o.k. if your floor slopes a little. If it has dips and humps in it though, these will have to be adressed before new flooring is installed. If you install tile, a cement leveling compound can be used. If wood, the unevenness will need to be fixed structurally.

3/16" difference in a 6' span is the most unevenness allowable.

Answer 2

any floor can be unlevel but they do make a floor leveling compound  any good hardware store or big box will carry it easy to use
