Open Data

As part of New York City's Open Data Policy, the Department of Housing Preservation and Development (HPD) will use this page to post or link to various data we collect in the course of doing business. Among other things, this will enable computer programmers and app builders to create applications and tools that could improve access to public information and put it at the fingertips of tenants, landlords, developers, elected officials, housing advocates, and other interested parties.

Please note that HPD's information sets are generally large. The information files are in a standard XML format. The XML format is defined in schema files that accompany the information files. There is also a file explaining the information we're providing and the schedule for new releases. For each information set we're making available, we distribute two zipped files. The first is a spreadsheet detailing what data we are making available and how that data is organized (schema files). The second file contains the information. For questions about HPD's Open Data, contact us at OpenData@hpd.nyc.gov.
