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. NYC-DB 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.
NYC-DB builds a postgresql database containing the following datasets:
- Department of City Planning's Pluto: versions 16v2 and 17v1
- DOB Job Filings
- DOB Complaints
- HPD Violations
- HPD Registrations
- HPD Complaints
- Department of Finance Rolling Sales
- Tax bills - Rent Stabilization Unit Counts (John Krauss's data)
- ACRIS
NYC-DB is a python3 command line program that downloads and loads datasets into postgres.
Just want a copy of the database?
Here are the latest versions available to download from S3:
It's ~2.5gb compressed and ~14gb decompressed.
If you have aws cli installed, you can download it easily this way: aws s3 cp s3://nyc-db/nyc-db-2018-08-05.sql.bz2 ./
To decompress: bunzip2 nyc-db-2018-08-05.sql.bz2
Load the db: psql -d database-name -f nyc-db-2018-08-05.sql
To manage and create copies of the database yourself, you can see the nycdb command line tool available on pypi: pip3 install nycdb
see src/README.rst for more information on using the command line tool.
As a convenience you can create the database in one go using this command:
make nyc-db DB_HOST=localhost DB_DATABASE=nycdb DB_USER=databaseuser DB_PASSWORD=mypassword
See the folder /ansible for ansible playbooks to setup the database on a sever.
