This is discrimination plain and simple. So 4 people can live together if they're not going to college?? But if they decide to get an education, let's punish them?

>"We need to do what we can to preserve housing for our residents"

Oh so students aren't residents?? Fuck off.

And don't get me started on affordable housing... so say there's a 5 bedroom house available, but sorry, you're only allowed to have 3 students live there. Way to simultaneously increase costs AND reduce supply.
