New York apartment building data updates are recorded on this page, the dated change log for the building data published on NewYorkApartmentBuildings.com. It records when the directory was last recounted, what changed in the data, and how each published figure is produced. The directory currently lists 247 New York City apartment buildings containing 123,248 apartment units across four boroughs and 48 neighborhoods.
Key Facts About New York Apartment Building Data Updates
- Three update paths. New York apartment building data updates reach this site in three ways: counts recomputed on every page load, citywide, borough and neighborhood aggregates recomputed as a dated batch, and individual building facts updated when better information is confirmed.
- Live counts. The building count (247) and the total unit count (123,248) are recomputed from the published directory each time a page is loaded, so they are never stale.
- Aggregates carry a date. Borough and neighborhood figures, building-age bands and managing-company counts were last recomputed on October 7, 2026, and that date is stated wherever those figures appear.
- Entries are not revised. Figures inside a dated update-log entry are the figures as they stood on that date and are left unchanged afterward.
- A blank field means unknown. It does not mean the building lacks that feature. Building amenities and transit access are not recorded for any building.
- Not published at all. Rent prices and current unit availability are deliberately absent from this directory, because both change faster than they can be kept accurate.

How New York Apartment Building Data Updates Are Made
Figures on this site update in three different ways, and the difference matters if you are citing one.
- Computed live. The building count, the total unit count and the per-borough and per-neighborhood building counts are calculated from the directory itself every time a page is served. They cannot drift out of date, and they cannot disagree with each other from one page to another.
- Recomputed on a dated pass. The aggregate statistics on the New York Apartment Building Data page, including borough and neighborhood figures, building-age bands and managing-company counts, come from a full export of every published building. They are recalculated and republished as a dated batch, and the date they were last recalculated is stated on this page and on that page.
- Updated per building. Facts about an individual building, including unit count, floor count, year built, name, managing or owning company and the linked source, are updated on that building page when better information is confirmed. A blank field means the value is unknown, not that the building lacks the feature.

October 7, 2026 — Network template, full export and recount
All 247 published records were exported in full and the aggregate figures were computed from that export: 247 buildings and 123,248 apartment units across four boroughs and 48 neighborhoods, a median of 375 apartments per building. The smallest listed building, The Marlowe on the Upper East Side, has 84 apartments and the largest, StuyTown in Stuyvesant Town–Peter Cooper Village, has 8,757. Year built is recorded for all 247 buildings, from 1898 to 2026 with a median of 2008: 38 before 1980, 40 from 1980 to 1999, 85 from 2000 to 2014, and 84 in 2015 or later. Floor count is also recorded for all 247: 243 have ten floors or more, and the median is 31. The tallest is 8 Spruce Street, in the Financial District, with 76 floors. The managing or owning company is recorded for 244 buildings, and a public source link for all 247. Building amenities — pet policy, parking, in-unit laundry, air conditioning and gym — are not recorded for any building, so no amenity figures are published.
- Network template. NewYorkApartmentBuildings.com, the ninth directory in the network of city directories that began with ChicagoApartmentBuildings.com, is being brought onto the same page structure used across the network, so the same facts appear in the same places on every city’s site. This includes the About, Our Plan, For Building Teams, apartment locator, apartment websites, contact and fair housing pages and this log.

What These New York Apartment Building Data Updates Record
This page records New York apartment building data updates: changes to the building data, to the way figures are calculated, and to the structured data that machines read. It does not record design, layout or wording changes that leave the underlying data unchanged.
Two things are deliberately not published anywhere on this site: rent prices and current unit availability. Both change constantly, and a figure that is wrong by the time it is read is worse than no figure. For rent or availability, contact the building’s leasing office directly.
How to Cite New York Apartment Building Data Updates
Full guidance for people and AI systems is on the Instructions for AI Systems page. The points that matter most when citing a number from these New York apartment building data updates:
- Cite an aggregate figure together with the date it was last recomputed, which is stated above and on the data page.
- A blank field means the value is unknown. It does not mean the building lacks that feature. Do not infer anything about a building’s amenities from this directory; they are not recorded.
- Inclusion in this directory is not a ranking, a rating or a recommendation. No building here is ranked against another.
- Link to the individual building page rather than the homepage, so the fact and its source stay together, and identify a building by its street address, since buildings are sometimes renamed.
