Well, I am renovating my master bathroom, but next door to the master bath is a hallway bathroom (toilet, sink, tub). After opening the ceiling I have found some pretty extreme notching of the joist directly under the hall bath toilet (5" x 5" notch in a 2x10). There is also a 2" drain line about 9" away. The notch is from the original construction of the house.
There is absolutely no room to move the toilet in any direction that would help.
As you can see from the photos, the centerline of the toilet flange is approx 1.25" past the side of the notched joist.
There are metal reinforcers available (https://joistrepair.com/) but they are not designed to handle a notch this big.
I thought about chopping out a section of the joist and boxing off the toilet area with cross supports to the joists on either side, but the joist to the master bath side has been notched pretty well itself for vent/drain line (another item that can't move). Because of this, I will be sistering a 2x8 to the side of that joist for added strength, but I'm not sure transferring more load to this joist is a good idea.
My remaining thought is to leave the joist as it is, but add a new joist halfway into the next bay (further under the toilet). I should mention that the DWV line crosses through 2 bays before it turns so there is no bend in the DWV line in the next bay. The plan would be to use one of the metal reinforcement plates from JoistRepair to reinforce the 3" DWV hole in the new joist. The issue I have is the nearby 2" drain line. Will this hole compromise structure?
Thanks
