Two city datasets sit behind this. The Department of City Planning Housing Database records every job that adds or removes housing, from the permit application through to completion. Figures by community district run 2010 to 2024. Figures by council district and neighborhood come from the individual job records and run 2010 to 2022, which is why those totals are lower.
Net unitsEvery figure here is net. If a block loses 20 units to demolition and gains 50 in a new building, it counts as 30. An area can post a negative year.
CompletedConstruction finished and the units exist. This is the default view.
Permitted, not yet builtThe city has issued a permit and work can begin. The furthest along in the pipeline, and the most likely to actually appear.
FiledAn application has been submitted but not yet approved. The least certain stage; many filed jobs are later withdrawn.
New buildingHousing on a site that had none, or replacing what was there. The large majority of what gets built.
AlterationUnits added by converting or enlarging a building that already exists. More jobs than new construction, but far fewer units each.
DemolitionUnits removed. Subtracted from every total on this page.
Income regulatedUnits with a legal cap on rent tied to household income, counted toward the city’s affordable housing programs. Everything else is market rate.
Dwelling unitsConventional apartments and houses, what the city calls Class A. Hotel rooms and group quarters are counted separately and are not part of the housing totals.
2020 census unitsEvery housing unit that existed at the 2020 count, used here to show how much an area grew relative to its size.
The three lenses. The same data, cut three ways. Community boards are the 59 districts that review land use locally. Council districts are the 51 seats whose members hold the deciding vote on most rezonings. Neighborhoods are the names people actually use, which follow neither boundary.
Colour bands on the map are relative to the areas shown, not a fixed scale, so the same colour means different things when you switch lenses.
