How to Use.

Currently the Dap.Map has three primary data view options and one combined risk score view, each based on data compiled by ANHD. Dap.Map analyzes:

  • Loss of rent-regulated units in the building.

  • Volume of NYC Department of Buildings permits that indicate a high rate of tenant turnover.

  • Level of building sales prices that indicate a speculative building purchases.

  • Combined score of indicators that indicate building and tenant vulnerability.

Each view color-codes the buildings by risk-level so the information is clear and intuitive. The Dap.Map also includes a Council District View Tab and a Community District View Tab, which allows the viewer to quickly zoom in to a specific area. In each Dap.Map option bulleted above, the user can find more information about a particular building by clicking on the building lot.

Loss of Rent Regulated Units

Is there a high rate of loss of rent-regulated tenants in the building? This map shows the percentage of rent regulated units lost in each building between 2007 and 2014, color-coded to show the buildings with highest-percentage loss. This percentage is calculated from the number of rent regulated remaining in 2015 in comparison to the number off rent regulated units present in 2007. This map includes all apartment buildings with at least 1 rent regulated unit between 2007 and 2014 in buildings with more than five residential units.

Volume of DOB Permits

Do NYC Department of Buildings permits indicate a high rate of tenant turnover? This map shows the number of NYC Department of Buildings work permits (types Alt 1, Alt 2, Alt 3, and Demolition) in each building since 2013, color-coded to show the buildings with highest percentage of work permits . These permits indicate apartments that have become vacant and been upgraded by the landlord, often allowing for major rent increases that are a motivating factor in displacement. This map includes all residential buildings with some permit activity between 2013 and 2015 and for buildings with more than five residential units.

Level of Property Sales Price

Was the building sold for a price that might indicate a speculative investment strategy?  This color-coded “heat map” indicates if a recent  per-unit sale price of the building is greater than an average neighborhood price, which may be an sign of a speculative investment strategy.  The Property Sales price per unit of each building across the City is compared to the average property sales price per unit across the Community Board in 2010. This map only includes recent sales of apartment buildings over $100, taking place between January 1, 2015 and December 31, 2015.

Combined Building Risk Indicator

Where do we see building facing multiple combined risks? This shows the building risk score, indicating if the combined sales price, loss of rent stabilized units, and number of NYC Department of Buildings permits suggest that affordable housing in this building is at especially high risk. This map includes all apartment buildings with more than five residential units that have at least one of the 3 displacement indicators. Each indicator category is scored from 0-100. And they are combined so that a building has the biggest loss of rent regulated units, the highest number of DOB permits, and the must speculative sales price will have a score of 300. Building that only had 1 indicator – i.e. only had DOB permits, but no property sale and no loss of rent regulated units – can only score a high of 100 points.
