The NYC Department of City Planning’s (DCP) Housing Database contains all NYC Department of Buildings (DOB)-approved housing construction and demolition jobs filed or completed in NYC since January 1, 2010, this version also includes inactive jobs. It includes all three construction job types that add or remove residential units: new buildings, major alterations, and demolitions, and can be used to determine the change in legal housing units across time and space. Records in the Housing Database are geocoded to the greatest level of precision possible, subject to numerous quality assurance and control checks, recoded for usability, and joined to other housing data sources relevant to city planners and analysts.

There are two versions of the project level Housing Database:
1) HousingDB_post2010 - all active and completed jobs
2) HousingDB_post2010_inactive_included - all active, completed jobs and inactive jobs (includes withdrawn, stalled, or duplicate jobs)

Data are updated semiannually, at the end of the second and fourth quarters of each year.

Please see DCP’s annual Housing Production Snapshot summarizing findings from the 22Q4 data release here. Additional Housing and Economic analyses are also available.

All previously released versions of this data are available at BYTES of the BIG APPLE- Archive.

Net change in housing units arising from new buildings, demolitions, or alterations for specified geography (Census Block, Census Tract, City Council district, Community District, Community District Tabulation Area (CDTA), Neighborhood Tabulation Area (NTA). These tables are aggregated from the DCP Housing Database, which is derived from Department of Buildings (DOB)-approved housing construction and demolition jobs filed or completed in NYC since January 1, 2010. Net housing unit change is calculated as the sum of all three construction job types that add or remove residential units: new buildings, major alterations, and demolitions, and can be used to determine the change in legal housing units across time and space.

NOTE: Housing Database by PUMA has been sunset as of the 20q4 release. Anyone looking for housing database at the PUMA level should use the Housing Database by 2020 CDTA dataset, which is a similar geography but not an exact equivalent.

All previously released versions of this data are available at the BYTES of the BIG APPLE Archive.
