Looks that way to me too.


Look more carefully. It's just an optical illusion. What
you're seeing
behind the joist is the subfloor, not another joist.

Now that you point it out, I certainly agree. The
perspective fooled me.

Something needs to be done...

I disagree with it being sub-floor. The sub-floor is OSB.
The "joist" has a side and a bottom. You can see what
appears to be OSB in the gap on the right of the vertical
pipe. The uncut joist is probably supporting a wall behind
the toilet flange that is visible on the pipe. Sister the
cut joist to assure a solid toilet installation.
