Here you can look up the BBL if you only have the address, find out the registration of the building, census tract, stories, units, and emergency repairs.

ACRIS The Department of Finance has created Automated City Register Information System (ACRIS) that allows users to look up property records and transactions on specific properties searching by block and lot number, or do research on a particular party name. Mortgage and deed transactions are posted, and many include scanned images of the actual documents.

Department of Buildings Building Information System The Department of Buildings (DOB) offers real-time Building Information System data including a property profile overview containing detailed complaint information. It includes DOB violations as well as Environmental Control Board violations. You can also sometimes view the Certificate of Occupancy for a property, or any permits issued.

The New York City Open Accessible Space Information System Cooperative (OASIS NYC) allows users to look up property information and block and lot maps, searching by address or block and lot. You can find out lot size, zoning information, ownership info, and links to other property information.
