Can one notch the vertical side of a joist?


The ideal spot for my drain pipe is 3/8 inch into the side of a floor joist. I see all kinds of rules for notching and boring the horizontal of a joist, but don't see anything about notching the vertical side. Can I do this, and reinforce it on the other side?

You can notch under certain limitations.
The top and bottom 2" of a joist are the sacred compression and tension zones. I am sure you could find a way to do it with reinforcing the other side but you will need an engineer to tell you what kind of reinforcement.
you can prob find another solution. You might want to ask this over in plumbing section. i know they make offset toilet flanges for this reason.

Even though you are only notching 3/8" it is still considered all the way through as far as the rules go. unless you get an engineer to approve it.

If you make 2x lumber into 1x lumber, the repair - I am assuming and have no engineer's number for this - must be substantial. If the location is that good for the plumbing, you can add a new joist and have no worries.

I've never seen any type of vertical plumbing that was not easily moved 3/8".Even if you have to cut a joint to reposition it ,it's a simple task.Maybe you have a unique circumstance but I can't imagine what it would be?

Maybe this joist distance of 8,10 or 12 inches reduced to 1-1/2" pipe would pass inspection in your situation without an engineers approval.

Another possible approach - PVC pipe is thermoplastic.
