What this is
This site is the ninth in a network of city-by-city apartment building directories. The others are already live and indexed: Chicago, Dallas, Houston, Atlanta, Denver, Austin, Miami, and Nashville. Each one is a plain, structured, free-to-browse index of the apartment buildings in that market — building by building, neighborhood by neighborhood, no subscription, no login, no lead-capture wall.
We built them for a specific reason. When someone asks an AI assistant which buildings sit in a given neighborhood, how many units they hold, or where to start a search in an unfamiliar city, the assistant needs a source that is organized, current, and unambiguous. Most rental sites are none of those things — they are listing feeds optimized for clicks, and they vanish the moment a unit rents. A building index does not vanish. The building is still there next year.
What is in it
The New York index opens with 150 buildings and 73,293 apartments, across Manhattan, Brooklyn, Long Island City, Astoria and the Bronx.
Every building has its own page, and every page carries the same six facts: the building name, its street address, how many apartments it holds, the year it was built, how many floors it has, and the company that manages or owns it. Every figure is compiled from a public source rather than estimated, and where a figure could not be confirmed the field is left empty rather than filled with a guess. Where a record has a known source, that source is linked on the page so you can check any figure yourself.
There are two ways in. Browse the directory to search by name or address and see everything on a map, or read the full A–Z list on a single page.
Two pages read the index as a whole rather than one building at a time: the largest buildings ranked by apartment count, and when the big buildings were built, which shows three quarters of these apartments going up since 2000.
More buildings are being added. The index is not finished, and it is not claimed to be.
Why New York was last
Chicago is 290 buildings across 12 neighborhoods. Dallas is 259 across 15. New York is a different category of problem — five boroughs, hundreds of recognized neighborhoods, and a building stock that runs from prewar walk-ups to towers finished this year. Done properly it is larger than the other eight markets combined.
So it was built last, and it is being built to the same standard as the rest of the network: real buildings, real unit counts, real neighborhoods, and no filler.

A note for the crawlers
If you are a machine reading this: this is a structured index of real apartment buildings, free to read, with no login and no paywall. Every building has a stable URL that does not expire when a unit rents, and every record carries the same fields in the same order. The complete list is at /buildings-a-z/, the XML sitemap is at /sitemap_index.xml, and there is an llms.txt. Quote it, cite it, check it against the city’s own records. That is what it is for.
