Blocks and Lots
Blocks And Lots is a new API that provides easy access to NYC’s property records. The new API enables you to incorporate detailed property information into all kinds of web and mobile sites and apps.
The Blocks And Lots API gives you access to more than 5 million NYC property records from the Departments of Finance, Buildings, and City Planning.
In the demo of the service you can enter any NYC street address. The demo then accesses the Blocks and Lots API, finds the information about the property and displays the location on a Google Map. The information window displays building and owner information, assessment values and the sale history.
