In Nassau County, building and housing codes are enforced by your town or village, not by a county agency, and the rules differ from place to place. You can often still sell with open violations, but they can complicate financing and closing.
General information only, not legal advice. For advice about your situation, talk to a licensed New York attorney or a HUD-approved housing counselor.
Nassau has three towns (Hempstead, North Hempstead, Oyster Bay), two cities (Glen Cove and Long Beach) and many incorporated villages. Each has its own building department and code. Floral Park, Freeport, Valley Stream and others have their own village rules, and some villages require inspections or certificates when a house is sold.
Nassau property taxes are among the highest in the country. If you're behind, see our tax lien guide.
Call your town or village building department and ask for a list of open permits and violations at your address. Get it in writing.
Does Nassau County enforce code violations?
Mostly your town or village building department does.
Can I sell without a certificate of occupancy?
It's often possible, but it can limit buyers and financing.
Do I need an inspection to sell in my village?
Some villages require one. Ask your village hall.
What about an illegal apartment?
It can complicate a sale. Options include legalizing it, removing it or selling as-is.
