Well, I passed two out of the three inspections today: electrical and framing. For plumbing, I need to cover the corners of the shower threshold, and cover any staples in the top of the threshold. But the bigger thing is that the vent for the sink drain needs to be higher...at least 6" above the level of the sink before it goes horizontal. It's doable to change, but it'll be some work. I remember reading about that somewhere, but obviously didn't remember that when I was installing the DWV pipes.
The more significant but easier change is that we probably won't be able to have the pocket door on the steps. Even though the door doesn't swing, the building code seems to say that we'd need a 36" landing on either side. Moving it back a little would get the hallway side OK, but that plus 36" on the other side doesn't work. It will be easy enough to put a swinging door at the top. And the inspector wasn't 100% sure as the code doesn't talk about a pocket door in this case, and said I could talk with the code check people and see if they'd OK it as-is. It's my fault for not re-doing the plans completely when I changed the bathroom to the bedroom level -- it probably would have been caught during code check before if I had. And better it's caught now than in a month when everything has drywall.
But everything else is OK, and I can put drywall on the ceiling, which means I can move forward with insulation. And more research is needed on the door. I need to follow the building code, but it'd be nice to have the pocket door as planned.
