We own a third floor condo in a house from the 1860s. I am trying to identify the load bearing walls in our apartment.
Wall A is load bearing because it supports the roof joists. But what about wall B? My assessment is that it is not load bearing because the roof and ceiling joists run parallel to it. However, I am having problems finding all the ceiling joists. Most are hidden under insulation but they seem to run parallel to Wall B and are supported by Wall C or A. But again, I can only see them in a few places. In addition, I poked some holes above the wood framing of the opening in wall B, and it's pretty much hollow (there is a stud right next to it).
