Can I sister the backside of the floor joist and then notch the front side so I can fit my drain in? I can find plenty of advice for drain that needs to go through the joist horizontally, but none when a toilet drain is above the joist.
The nail with green tape is dropped in from the bathroom above, in the center of the toilet drain. It's 1 3/8" from the edge of the joist.
