I am an architect in Richmond finishing off my attic to handle my growing family. I've finished framing, electrical, and mechanical, and am now designing the plumbing for an additional full bath. I know the building code well, but not the specifics of the plumbing code, so I thought I'd sign up and get some advice. The attached diagram shows what I think I need to do.
Due to the age and construction of the house, I don't want to cut any of the existing floor framing members, so I'm trying to plumb this accordingly. Blue is waste, yellow is vent. For the vanity I was going to use an AAV, and for the toilet I was going to pipe a vent to the roof. All the waste lines run parallel to the floor joists until they can drop down through the top of a closet, where they hook up and head down through the floor to tie into the main waste line in the crawlspace.
One error that I already know is that I need a long sweep tee where the tub drain connects into the toilet drain. Does anything else look like it won't pass code?
