A Certificate of Occupancy (CO) states a building’s legal use and/or type of permitted occupancy. New buildings must have a CO, and existing buildings must have a current or amended CO when construction will change their use, egress or type of occupancy.
No one may legally occupy a building until the Department has issued a Certificate of Occupancy or Temporary Certificate of Occupancy.
The Department issues a final Certificate of Occupancy when the completed work matches the submitted plans for new buildings or major alterations. It issues a Letter of Completion for minor alterations to properties. These documents confirm the work complies with all applicable laws, all paperwork has been completed, all fees owed to the Department have been paid, all relevant violations have been resolved and all necessary approvals have been received from other City Agencies.

Using the Property Address:
You can print a copy of a building’s CO from any computer. Use the Buildings Information System to look up the property. In the building’s profile, the “View Certificates of Occupancy” link will display the CO. You can also obtain a copy of a Certificate of Occupancy from the Department’s Customer Service Counter in your borough office.
Buildings built before 1938 aren’t required to have a Certificate of Occupancy – unless later alterations changed its use, egress or occupancy. If you require proof of a building’s legal use – and it’s exempt from the CO requirement – contact the Department’s borough office where the property is located to request a Letter of No Objection.
Owners must make sure a building or unit has a Certificate of Occupancy. In some circumstances, the Department may determine that a property is safe to occupy, but there are outstanding issues requiring final approval. A Temporary Certificate of Occupancy – or TCO – indicates that the property is safe for occupancy, but it has an expiration date. TCOs typically expire 90 days after they are issued.
The Department strongly recommends that you negotiate a closing based on a final Certificate of Occupancy, not a Temporary Certificate of Occupancy.
If you purchase a co-op, condo or house that has a TCO, consult with a New York State licensed Professional Engineer or Registered Architect to determine what work has to be done, and any outstanding issues in order for the building to receive a final CO.
Once you purchase a property, you, as the owner, have the legal obligation to make sure that the building obtains a final CO documenting its compliance with the Building Code and the Zoning Resolution. Because this is your responsibility, you should ask your attorney to obtain written assurance and sufficient escrow from the seller/developer to ensure that the developer actually finishes any outstanding work and obtains the final CO in a timely manner.
Note: When a TCO expires and is not renewed, it may be difficult or impossible to buy insurance or sell or refinance the property.
