I have an interior wall between kitchen and living room that I want to remove on the second (top) floor with nothing below it. This wall runs perpendicular to roof joists (non-truss) and parrallel to floor joists. I was under the impression that it was in fact load bearing until I removed all the sheet rock and discovered that this wall sits BETWEEN the floor joists. After more inspection, I noticed that the entire length of the wall is only sitting on the subfloor and not even on a floor joist. The ceiling framing does include a partial 2 by 10 (double) beam and scissored joists with tie backs to roof rafters. After showing the cavity below the wall to a contractor, he was sure that the wall is not load bearing due to lack of any support below the wall. I guess I want to be absolutely sure! Thoughts or comments?

Yes. Get an opinion from a qualified design professional, who can examine the entire house and take all possible existing conditions into consideration.

Thank you Richard for your timely response. Structural Engineer coming by in a couple of days. If nothing else . . . I get a little piece of mind and then when my kids ask if the house is going to fall down . . . I can tell them without worry that their toys are safe! Thanks again.
