New York Rent Regulated Buildings
In New York, many privately-owned apartments are subject to limits on the rent landlords can ask. The vast majority of these apartments are called rent stabilized. An older program, rent control, has even stronger limits on rent increases and evictions.
Owners of buildings with rent-controlled and rent-stabilized apartments must register them with the state Division of Housing and Community Renewal. This registry also includes information about housing subsidy programs that apply to these buildings. But be careful, quoth DHCR: "Inclusion on the list is not determinative of the building's current status."
The publically accessible dataset includes registrations going back to 1984. The dataset includes more than one entry for some buildings, reflecting registrations in different years.
The vast majority of properties are in the five boroughs, with a few properties in Nassau, Rockland and Westchester counties.
Using the data
The data is included as a CSV file: rentregulated.csv. The file has 68,000 rows and is 6.1 MB.
Makefile can be used to create an SQLite database or load the data into a MySQL database:
# create an SQLite db make rentregulated.db # load into a mysql database called rentregulated on localhost make mysql USER=myusername PASS=mypassword HOST=localhost
Additionally, `rentregulated.json is a GeoJSON file with geocoded addresses. A mix of Google, Mapbox and Mapzen geocoders were used.
Makefile also includes a script to download a new copy of the data. Note that the DHCR website is very slow and buggy, and download isn't a smooth process. The script requires Python 3.5 and two common prerequisites. Run
pip3.5 -r requirements.txt to install the prerequisites. Remove
rentregulated.csv then run
make to download the data. Running multiple processes is not recommended.
Because of the aforementioned bugginess of the DCHR site, this data may not be complete. Pull requests with verified additions are welcome.
- DCHR has provided basic information about the fields in the data set, but details about their methodology are missing.
- Some addresses are given as ranges ("6 TO 10 MAIN STREET").
- Some properties have "additional addresses". The significance of these addresses is unexplained. This data is available on the DHCR site, but requires an additional step to scrape, so only the note that an additional address exists is included.
