Let's research the landlord! New York City is in a housing crisis. Some landlords leave their buildings in despair and let their tenants suffer without heat in winter. Others evict their tenants, legally or illegally, in order to flip buildings and profit off of gentrification. Affordable housing is a scarce resource.
Residents, lawyers, tenants, and organizers who want to use data in their struggle turn to proprietary databases and resources, like PropertyShark, designed for real estate or contend with CSV and printouts from city websites. nycdb aims to give technologists and researchers who want to volunteer their time helping community groups who are defending the city against the real estate industry a leg up by providing a ready-to-use database filled with housing data.
nycdb is a python program that downloads, processes, and loads the following public datasets into postgres:
- Department of City Planning's PLUTO (Includes the latest version via Open Data, and many other specific versions. See documentatino for details)
