In Washington State, they would want a wye or combo fitting there.
In some cases, I would wye off, and then turn up through the floor with a waste 90 el, making sure the vent line would be above the flow line of the waste line.
I would like to make a few obvious improvements to my DWV before the inspector comes. I actually had goofed and put in a horizontal vent line in one place. The previous posts on this site made me aware of the error....
I would like to install a sanitary tee rolled 45 degrees as a vent off of a horizontal drain. The vent line rises vertically from a street 45 degree bend attached to the the sanitary tee.
Is this an advisable (code worthy) design? I've been trying avoid using sanitary tees (I find their use confusing), but I am tight on vertical clearance.

In Canada, That layout is acceptable as long as you don't have anything draining into that branch. As long as its being used as a dry vent
