This page is the plan for the New York apartment building dataset behind this site. Our team is building the most complete and accurate record we can of every building in the directory, and we are asking the buildings themselves to confirm their own facts and supply the ones we do not yet have, so each listing gets as close to complete as possible. Below is what the New York apartment building dataset records today, what we are working to add, how it is built, what a blank field means, what we never publish, and what all of that means for you while you search.
Key facts about the New York apartment building dataset
The short version of the New York apartment building dataset, for anyone who wants the answer without reading the whole page.
- Coverage. 247 New York City apartment buildings with 123,248 apartments between them, in four boroughs and 48 neighborhoods, one permanent page per building.
- What each record holds today. Name, street address, borough and neighborhood, apartment count, year built, floor count, the managing or owning company, and a link to the public source for those figures.
- What we are working to add. Building amenities: pet policy, parking, in-unit laundry, air conditioning and a gym. These are not recorded today.
- A blank field means the fact is unconfirmed. It does not mean the building lacks that feature.
- Not published. Rent prices, current availability, specials, fees, lease terms, resident reviews, star ratings, and best-of rankings.
- Changes are dated and listed on the data updates page.
- Browsing is free and no account is needed.
What we are building
A factual record of every building in the directory, currently 247 New York City apartment buildings with 123,248 apartments. For each one, the goal is the facts a renter screens on before touring:
- Building size, floor count, year built and who manages it
- Parking and pet policy
- In-unit laundry, air conditioning and building amenities
The first of those is in place: size, floors and year built for every building, and the managing or owning company for 244 of the 247. The other two are the work in progress.
What the New York apartment building dataset records
Each building is one factual record. The fields are the ones a renter uses to rule a building in or out before spending an evening touring it.
Size and age. Apartment count, floor count and year built are recorded for every building in the directory. They tell you what kind of building you are looking at, from a 13-floor 1947 building at StuyTown to a 76-floor tower in the Financial District, and set expectations for scale before you visit.
Identity. Each building is recorded under its own name and published street address, in its borough and one of 48 New York City neighborhoods, with the company that manages or owns it and a link to the public source its figures came from. Building names change — a property can be rebranded after a sale or a renovation, and listing sites do not always keep up. Where a building has been renamed, the street address is treated as the reliable identifier rather than the name. Every building is filed under its borough first — Manhattan (171), Brooklyn (44), Queens (27) or the Bronx (5); no Staten Island building is listed yet — and then under one of 48 neighborhoods, many of which hold only one to four buildings. The mailing city on a building page follows its postal address, so Queens buildings appear as Long Island City (23) or Astoria (4).
Screening rules and daily living — still to come. Parking and pet policy are the two facts most likely to end a search before it starts, and in-unit laundry, air conditioning and building amenities are what you live with after the move. The directory does not record any of them today, and it does not record subway or transit access. We are working to add amenity facts, building by building, and the fastest source is the building’s own team.
How the New York apartment building dataset is built
- Research first. Every building page carries six facts — name, street address, apartment count, year built, floor count and the managing or owning company — compiled from a public source rather than estimated, and that source is linked on the page. Most often the source is the property’s own website or the owner or manager’s portfolio pages; otherwise it is a real estate reference such as StreetEasy or CityRealty, or published coverage of the building. Where a figure could not be confirmed, the field is left empty.
- Then the buildings. We are asking each building’s team to confirm its facts and fill the gaps, starting with the amenity facts the directory does not yet hold. Nobody knows a building better than the people who run it.
- Then we keep it current. When better information is confirmed, the listing is updated, and dated changes are recorded on our data updates page.
Those three steps repeat. A listing is never finished: it is the best record we have today, and it gets better every time a building confirms a fact or fills a gap.
Our standard for the New York apartment building dataset
- Nothing made up. If we can’t back a fact, we don’t publish it, and the source is linked on the building page.
- A blank field means unknown. It does not mean the building lacks that feature. Those blanks are exactly what we are working with the buildings to fill.
- No reviews, ratings or rankings. Just the facts, so you can compare buildings on your own terms. Nobody pays to be included or excluded.
What a blank field means
A blank field in the New York apartment building dataset means we have not confirmed that fact for that building. It does not mean the building lacks the feature, and it does not mean the answer is no.
Amenities are the clearest example. The directory does not record building amenities — pet policy, parking, in-unit laundry, air conditioning or a gym — so confirm any of those with the building’s leasing office. Until a building’s amenities are recorded, treat the question as open rather than answered, and if it matters to your search, ask before you rule the building out.
Filling those blanks is the main reason we are asking building teams to work with us. Nobody can confirm a pet policy or a parking arrangement faster than the people who run the building.
What the New York apartment building dataset does not include
Three things are deliberately absent: rent prices, current availability, and resident reviews or ratings.
Rents, availability, specials, fees and lease terms are not on this site, and there are no lead forms. They change faster than they can be kept accurate, they belong to the building, and a wrong price is worse than none. For those, check with the building directly.
Resident reviews and star ratings are not here either. A review is one person’s experience: one unit, one leasing agent, one maintenance request, at one moment in time. Two residents of the same building can live there very differently, and a building can change management, staff or policies after a review is written. What we publish is what doesn’t depend on anyone’s opinion: the facts about the building itself, so you can decide what matters to you.
The New York apartment building dataset also does not rank buildings. There is no best-of ordering and no score. The A–Z index and the borough and neighborhood pages are arranged for browsing, not as a recommendation, and no building’s position on them is a judgement about it.
Checking a building’s record yourself
None of this asks you to take our word for it. Every building page links the public source its figures came from, and the building’s own website and New York City’s public records — ACRIS for recorded property documents in Manhattan, Brooklyn, Queens and the Bronx, and HPD Online for a building’s registration, complaints and violations — are ways to check a building independently of any listing site. Where newer information verified from a primary source conflicts with a listing, the newer verified information should be used.
If you find something in the New York apartment building dataset that is wrong or out of date, or a building that belongs in the directory and is not here yet, tell us and we will look at it. Email chicagoapartmentbuildings@gmail.com with the building name, street address and what needs changing.
What this means for you
Apartment hunting means checking a lot of sites. We want this one to be the place you trust for the building facts, and the listings get more complete every time a building works with us. Start by browsing buildings by borough and neighborhood, the map, or the A–Z list.
