Good luck to anyone trying to figure out NYC rent control laws. But I think the idea might be to make more units subject to rent control, which owners are obviously going to hate and which might provide more affordable, but often unimproved, housing.
A fair point. With inflation and labor issues, nobody is going to want to develop fully rent controlled housing. The solution might lie in making some units subject to rent control in larger developments. But that requires one to understand the rent control laws, and good luck with that incomprehensible mess.
