Hi! I want to reroute my drain so that it is not below the joists to finish the ceiling in the basement as high as possible. Notching one 2x8 joist at the bottom would do the trick. It isn't up to code to do it but I have old notches in other places, and it's only one joist, it spans about 20ft (with a beam in the middle) and the notch would be around 4ft from one side. Is there a way to reinforce the joist before/after notching it a little less than 2 inches?
