I've removed all the soffits in my kitchen, however, there is one 2x4 that I have left until I could consult someone more knowledgeable. I'm thinking the 2x4 was there just to hang the drywall underneath, however, it seems to run along the bottom of 2x10's that make up my exterior wall (sill?) that supports the floor joists of my 2nd floor. The house is a 2-story, brick home built in 1940.
I'm thinking the 2x4's that run up the wall should be toenailed into a single 2x4 that runs the bottom of those 2x10's but I can't see without taking out some more drywall. Is it possible that this stud is structural in any way? Thanks.
