To find out who owns your NYC building, search two free public records: the deed on ACRIS (which shows the legal owner, often an LLC) and the building's HPD registration (which names the real people responsible for it). Together they reveal both the company that holds title and the human being behind it. You can search all of this by address, for free, at Check a Building.
The rest of this guide walks through exactly where each record lives, what it tells you, and how to see past the LLC that so many New York landlords hide behind.
Why it's worth knowing who owns your building
Knowing who owns your building isn't about judging anyone — it's about having the facts. If you need repairs, want to send a formal complaint, are checking whether the same landlord runs other buildings with a track record of violations, or simply want to know who's actually cashing your rent check, the owner's identity is the starting point. All of this information is drawn from public property and ownership records maintained by the City and State of New York. It's tenant education, not tenant screening.
Start with the deed: ACRIS
ACRIS (the Automated City Register Information System) is New York City's official database of property documents. It records every deed, mortgage, and lien filed against a property going back to 1966, and it's free to search on the NYC Department of Finance website. The document you want is the most recent deed — not a mortgage, not an assignment. The deed names the current legal owner of the building, exactly as it was written when the property last changed hands. Here's the catch: in a large share of NYC, the name on the deed isn't a person. It's a limited liability company — something like "123 Main Street Holdings LLC." That's the shell-LLC problem, and it's the single biggest obstacle tenants hit when trying to figure out who their landlord really is.
The shell-LLC problem (and how to get past it)
Many New York property owners hold each building inside its own LLC. There are ordinary business reasons for this — limiting liability and organizing taxes — but the side effect is that the deed alone often tells you nothing about the actual human owner. Fortunately, an LLC on the deed is usually not the end of the road: HPD registration (covered next) forces most residential buildings to name a real person behind the company. The New York Department of State business entity search lets you look up the LLC by name to see its formation date, status, and registered address. When the same person or address appears across multiple LLCs, you can start to see a larger portfolio behind separate-looking companies.
The record that names a real human: HPD registration
This is the key step most people don't know about. Under New York City law, owners of most residential buildings must register annually with HPD (the Department of Housing Preservation and Development). Registration is generally required for any building with three or more residential units, and for one- and two-family homes where neither the owner nor the owner's immediate family lives in the building. Crucially, the registration must name real people, not just the LLC: the head officer (typically the owner or a principal behind the company), the managing agent (a person who must live in or keep an office in New York City, and who is legally responsible for the building's day-to-day operation), and often a site manager or emergency contact. Why does the law require actual humans? Because the city, tenants, and process servers need someone they can reach and legally serve notice on. You can view this on HPD Online, HPD's free public lookup, by entering your address. A building that is missing or has an expired registration is itself a meaningful fact — landlords are required to keep it current.
Putting it together — the free way
You don't have to visit three separate government websites and cross-reference them by hand. Check a Building pulls these public records together — ACRIS ownership, HPD registration, and related data — so you can type in an address and see the owner of record, the registered head officer and managing agent, and how the pieces connect, all in one place, for free.
If you'd rather go source by source:
- Search ACRIS by address or BBL and open the most recent deed to get the legal owner.
- If the owner is an LLC, search the NY Department of State business entity database for that exact LLC name.
- Search HPD Online for the same address and open the registration to find the head officer and managing agent.
- Note any repeated names or addresses across records, which can reveal a larger portfolio.
How to read what you find (without jumping to conclusions)
A few honest caveats. Records can lag reality: a building may have changed hands since the last deed was recorded, or a registration may be a little out of date. The "head officer" named in an HPD filing is sometimes the beneficial owner and sometimes a representative or manager acting on the owner's behalf. And a managing agent is not necessarily the owner at all. So treat these records as a factual map of who is responsible for and connected to the building — not as a verdict on any individual. If something looks inconsistent, that's normal, and it's often a sign to check a second source.
What to do next
Once you know who owns and manages your building, you're in a much stronger position — whether you're requesting repairs, filing a complaint with 311 or HPD, or researching the building's history. Two closely related questions many tenants ask next:
- Is your apartment rent stabilized? See our guide on how to find out if you're rent stabilized, including how to request your official rent history.
- Has your building ever had a vacate order? Learn what a vacate order means and your rights if one is issued.
You can look up your building's ownership and registration for free anytime at Check a Building.
