You can research the history of a building using the Department's Buildings Information System. After entering an address, you will be taken to the Property Profile Overview. At the bottom of this page, you can select Complaints, DOB Violations or OATH/ECB Violations.
Check for any outstanding violations that have not been corrected and closed. Reviewing violations (even if they have been corrected) provides important information about the history and maintenance of the building.
On the Property Profile Overview page you can also select Jobs/Filings. Here you can verify if permits were obtained to do work on the building (if required). Also search DOB NOW for recent job filings and work permits. Certain work types including electrical, elevator, sidewalk sheds and boiler and façade compliance filings will be found in DOB NOW, the Department’s new self-service online tool.
