Is this a single, 2-3 family or 4 family and above apartment building?
What are the issues for c/o violation?
Linden typically doesn't have a c/o inspection so I'm guessing this is a 4 family or above building where the state would issue a green card certificate.
I hope you didn't do some damage and report the landlord to get out of a lease, that would be a big no...no... but I'm seeing it more and more lately among tenants with no scruples or class if you get my drift.
If the building is in really bad shape the state can shut down the building and the landlord can be help responsible to cover your housing elsewhere. Generally the state will just fine the landlord and demand repairs be made within a period of time before a re-inspection.
You might find that the health department will evict you, if they have a concern. If you have a lease, you might have an action against the landlord but it probably would not be worth fighting, as long as your security deposit was returned.
I'd start packing, if I were you.
