I'm told that the Hackensack School District increased by something like 100 students per year over the last 8 years or so. That's significant. As explained to me, extended families doubled or tripled-up in single-unit apartments when the recession hit. With the economy gradually improving, the numbers may drop but only very gradually.
I think enforcement is very important. That said, I don't know how you tell someone that their recently unemployed brother and his kids can't stay with them temporarily. Unless there are obvious, reported code violations, it is difficult if not impossible to legally identify, let alone remedy. Proof of residency is relatively easy to demonstrate. But can we make students/parents prove they are living in code-compliant housing?
It's easier to prove when a student is not
living in town (and I hear this happens with some frequency) but the real problem appears to be overcrowding within
Hackensack. It's much harder to establish that a student is living in illegal, overcrowded conditions. How is this done? Even if you correlated enrollment data (last names) and building data (number of bedrooms), that might only reveal that cousins share a bedroom. There's no law against that.
And, to make matters worse, this overcrowding is not safe. Remember the fire on Anderson
behind the convent?
