Dear Newburgh Tenant:
Get in touch with the New Windsor Building Department. That is the best source to discover if there is a local law restricting occupancy.
This is a link to the state law allowing your family to live together in one home subject to local law relating to overcrowding:
Section '8' of the statute allows local code to triumph over the general provisions prohibiting a landlord to restrict occupancy:
">>>8. Nothing in this section shall be construed as invalidating or impairing the operation of, or the right of a landlord to restrict occupancy in order to comply with federal, state or local laws, regulations, ordinances or codes. >>>"

The answer provided to you is in the nature of general information. The general proposition being that you should try to avoid a bad outcome if you can.
