Hi Guys, I am removing an interior wall in a second floor bedroom. The house is 10 years old with engineered trusses. I had two contractors in the attic who told me the wall I am removing is not load bearing.

So today, I started taking the sheet rock down and I see four 2x4s nailed together in one spot and two 2x4s nailed up in another.

I am not sure what to make of this...

Thanks for your help...

 

Welcome to the forums.

What is directly below those 4 studs ?

 

I would be asking what's above it. Plus why does an interior wall have osb on one side like a shear wall does?

 

I have engineered trusses in my house. While it is very common for there to be no load bearing interior wall in a trussed house I have a couple in my house. You'd have to be quite knowledgeable about trusses to be able to tell by looking in the attic. In your case a wall sheated in OSB could be a shear wall (structural) and four studs right next to each other can be supporting a point load or beam (also structural).

Do you have a box of paperwork that came with the house? Hopefully it has the truss documentation. That would be the easiest and surest way to know if that wall is load bearing.
