pretty much what you said. Although the apartment doesn’t look like a crummy dump by Brooklyn standards.
We responded to that problem by making plans for other, newer, better buildings to move to ~ one of which was the New York Bulk and Foreign Facility. They pushed some pilings down too deep and tapped NATURAL GAS. That required spending $60 million on gigantic fans to blow the gas out from under the half billion dollar structure so it was safe to work in.
Just all sorts of things happen around there.
BTW, by Brooklyn standards her apartment looks great ~ it has a ceiling, fire safety system (those water pipes), windows ~ I know a young lady who's a friend of the family who lived for 8 or 9 months in an INTERIOR room that'd formerly been the hallway entrance for half a dozen other one room apartments. No airflow, no heat, no cooling, no independent control of the lights, and so forth. New York thought that was just great.
