CoreData.nyc Subsidized Housing Database

  • Does the Subsidized Housing Database include all subsidy programs?

    The Subsidized Housing Database includes many, but not all, housing subsidies in New York City. We will continue to update the database as data becomes available.

  • How can I access a property’s regulatory agreement(s)?

    When a property on the map is selected.  The control panel will include a link to the New York City Department of Finance’s Digital Tax Map, where additional information on the property is provided. From the Digital Tax Map, a link is then provided to that property’s records on the New York City Department of Finance’s Automated City Register Information System where regulatory agreements can be found.

  • Can a single property receive multiple subsidies?

    Yes. Many properties receive multiple sources of tax, financing, and other government subsidies.

  • Can a single subsidy agreement apply to multiple properties?

    Yes. A single subsidy agreement may apply to more than one property. In CoreData.nyc, the subsidy will be listed for each property it is associated with.

  • Can I estimate the number of affordable units in my building using the Subsidized Housing Database?

    No. The residential unit count provided in the Subsidized Housing Database refers to the total number of residential units in a property.The Database does not report the number of affordable units in a property, which can be determined by examining the regulatory agreements applicable to the property (available on the New York City Department of Finance’s Automated City Register Information System). For more information about specific subsidy programs and their affordability requirements, see the Directory of NYC Housing Programs.

  • How do I cite the data?

    CoreData.nyc and its maps, tables, and other resources may be incorporated into your work and research, and may be cited as: NYU Furman Center’s CoreData.nyc. More detailed citation guidelines are available here.

  • Does the Subsidized Housing Database filter that I select affect the Neighborhood Indicator results, or vice versa?

    No. Selecting a filter in the Subsidized Housing Database does not affect Neighborhood Indicator results; and selecting a Neighborhood Indicator does not affect Subsidized Housing Database results. They will be displayed together on the map, although you can toggle each layer on and off using the sliders on the Control PanelNavigation >>
