A Certificate of Occupancy (CO) states a building’s legal use and/or type of permitted occupancy. New buildings must have a CO, and existing buildings must have a current or amended CO when there is a change in use, egress or type of occupancy. No one may legally occupy a building until the Department has issued a Certificate of Occupancy or Temporary Certificate of Occupancy. The Department issues a final Certificate of Occupancy when the completed work matches the submitted plans for new buildings or major alterations. It issues a Letter of Completion for minor alterations to properties. These documents confirm the work complies with all applicable laws, all paperwork has been completed, all fees owed to the Department have been paid, all relevant violations have been resolved and all necessary approvals have been received from other City Agencies. This dataset contains all Certificates of Occupancy issued since 7/12/12.

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. It includes the three primary 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 Project-Level Files 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. 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 21Q4 data release here. Additional Housing and Economic analyses are also available. The NYC Department of City Planning’s (DCP) Housing Database Unit Change Summary Files provide the net change in Class A housing units since 2010, and the count of units pending completion for commonly used political and statistical boundaries (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 Project-Level Files, 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. These files can be used to determine the change in legal housing units across time and space.
