Let's elaborate to: Cap condominiums and detached houses to 0. Apartment complexes is how people should rent.
It is, of course, an extreme scenario. As I said, this is absent good data. If we get a sense of the impact one would have if we limit it to 1, supported by data, sure - cap it to 1.
> Apartment complexes is how people should rent.
Why would you get to decide that?
Some people like to rent single family homes. Some because they have a large family. Some because that's just what they want. It's not ok to tell them they can't do that and must be forced to live in an apartment.
