What happens if my house has a missing certificate of occupancy on Long Island?

The short answer
A certificate of occupancy is the town's sign-off that finished work passed inspection and meets municipal standards. That can be a bathroom, a finished basement, or the original construction of the house. Every permitted job adds to the record.
If the town file does not match the house, there are two paths. Legalize the missing work, or disclose it on the listing so buyers make offers knowing the situation.
In my experience, most Long Island buyers still proceed if their lender is okay with it. Some lenders will not underwrite a house with an open permit or a missing certificate of occupancy. A cash buyer can buy the house. A financed buyer cannot always.
If the problem shows up in the title search instead of before listing, the contract decides what happens. The buyer can back out, take the house anyway, renegotiate, set up an escrow to fix it, or take a cash credit and make it their problem. That is why my pre-listing walkthrough covers certificates of occupancy and permits. Disclosure on the listing takes it off the table as a late negotiation tool.
Legalizing the work usually needs an architect. Sometimes the owner handles it. I do not run that process. I can open the door for an inspection and introduce an attorney or an architect who handles this work. The legal advice comes from them.
Disclosing the issue and selling as-is does not have to kill the sale. In my experience, it has not. A missing certificate of occupancy is common enough on Long Island that buyers often expect it, especially in a low-inventory market.
The standard Long Island contract treats a valid certificate of occupancy as a condition of closing. The problem is either resolved or priced in. It is not optional.
