Remodeling of attic

Kith101

I have a fairly old home built in 1952. The entire house is oak boards. The basement beams are 9" x 1-3/4". The spacing on them is anywhere from 12" to 16" (no 2 are the same, I live in an area of Ohio where you don't need permits for anything). The attic has the same oak wood but they are 2"x6" and are spaced 18" apart on the floor and the ceiling. The wood is so hard it's almost impossible to drill through.

What I'm looking for is would this floor be strong enough to support a 3/4" plywood floor? Currently only a few for walking around are up there now. I want to finish the entire attack for living space. I don't plan on anything very heavy up there. The space will be 53' by about 16'.

I have a lot more questions but the flooring is my first concern.

Generally, 2x6 are not enough to support a floor for living space. You could sister 2x10, but that will reduce headroom, if that is an issue. Also, you need a alternate exit if that is to become living space.

Would an oversized window and an escape latter be acceptable as a 2nd exit? I really don't see any other way.

Just because you don't need permits is no reason to guess on this.

Yes there are a lot of people on here who know what they are doing, but they can't see your project.

You need to have a structural engineer walk through and tell you what will make it safe.

They may tell you that you can sister the studs with another 2x6 rather than the 2x10 mentioned above.

They may not. You don't want to guess on this stuff, it's too important.

Lives are literally at stake.
