The plumbing inspector never showed up! I talked to the building manager here, and she said she lets inspectors into the units all the time, during office hours (9:00 a.m. - 4:30). I then called the general contractor and asked them to re-schedule the inspection for another day, after 9:00, and they said OK. And then she can schedule the final building inspection likewise, unless there's some compelling reason for me to be here. Hopefully no more days off for Home Depot! Yay!
