Having 2 Families in a Single Family Home in NJ?

[Jehan Jaleel]

Just asking hypothetically of course. Suppose you own a Bi Level two story house but you are having hard time finding good renters for the whole house. And suppose you found 2 families who you really like and who like the house but cannot afford the rent.

Would it be possible to give each family one floor of the house? Suppose they both agreed to sharing the house and they each had a separate entrance.

Is this illegal or a violation? If it was, what is the worst that could happen to you if you were an NJ landlord an one of the tenants later had a disagreement with you and decided to inform the Man.
