Finding Out Who Owns Your NYC Building

Start with the building's property registration on file with the Department of Housing Preservation and Development, which names the owner or corporate officers and the managing agent. Then confirm the legal owner of record by searching ACRIS, the city's index of recorded deeds, using the address or the building's Borough-Block-Lot number. Both searches are free, and together they tell you who owns the building and who signed for it most recently.

Starting With the Building's HPD Registration

New York City requires the owner of most residential buildings to file a Property Registration Statement with HPD every year. The requirement covers any building with three or more residential units, and any one or two-unit building where neither the owner nor an immediate family member lives. Registration runs annually between May 21 and September 1, and it has to be updated any time ownership changes or the managing agent changes.

The statement has to include the owner's name and address, and if the owner is a corporation, the name and address of any officer whose ownership share is more than 25 percent. If a partnership owns the building, the same 25 percent rule applies to limited partners. The form also requires the managing agent's name, address and a phone number where someone can be reached, and the managing agent must keep a business address inside New York City. Search the building's address at the Building Health X building lookup and the report shows this registration information alongside the building's violations, so you do not need a separate HPD account to see it.

A building without a valid registration is not automatically hiding its owner. More often the paperwork is out of date. Under Local Law 71 of 2023, failing to register carries a civil penalty of $500 to $1,500 for a building with five units or fewer and $1,000 to $5,000 for larger buildings, and an owner with an invalid registration cannot even bring a nonpayment case against a tenant in Housing Court until it is fixed. A gap in registration is its own red flag before you dig further.

Searching Deeds and Mortgages on ACRIS

ACRIS is the Department of Finance's City Register Information System, and it holds every deed, mortgage and related document recorded against city property. It is free to search at the city's ACRIS site. If you only have a street address, use the "Find Addresses and Parcels" search first, choose the borough, and enter the house number and street name to get the building's Borough-Block-Lot, or BBL. Once you have the BBL, the "Parcel Identifier" search is the most precise way in, since it skips any mismatch in how the street name is spelled.

Set the Document Class filter to deeds and other conveyances to see every transfer, and results list in reverse chronological order, so the top row is the most recent one. Click any row to open the scanned document.

Reading the Deed

A deed names the grantor, the party giving up the property, and the grantee, the party receiving it. The most recent grantee on file is the current owner. The document also lists the consideration, which is the sale price, and the date the document was recorded. Most residential transfers in the city use a bargain and sale deed with a covenant against the grantor's acts, which the New York City Bar Association's guide to real property deeds describes as offering no guarantee that the title is clear, only a promise that the seller did nothing to encumber it. That is normal for an arm's length sale and is not on its own a warning sign.

Checking the Mortgage Too

Change the Document Class filter to mortgages and you will usually find a mortgage recorded the same day as the deed, since most buyers finance a purchase. The mortgage names the borrower, and that name should match the grantee on the deed. If it does not, or if you see a second mortgage recorded years after the first with a different lender, that can mark a refinance rather than a sale, which is worth knowing before you assume every new document means new ownership.

Telling If a Building Recently Sold

Sort the deeds by recorded date and compare the newest grantee name to the name on the building's HPD registration and on any older ACRIS documents. A new grantee name on a recent deed is the clearest sign of a sale. Keep in mind that recording lags behind the actual closing, sometimes by a few weeks, so a sale that closed very recently may not show up yet. If the building's registration still names the old owner while ACRIS shows a new grantee, the registration is out of date, since owners have to update it whenever ownership changes.

Checking Department of Finance Records

The Department of Finance's Property Tax Public Access portal, reachable through nyc.gov/nycproperty, lets you look up a property by address or BBL and see its tax class, market value and the account's tax bills and notices of property value. It will not name the owner directly, but it lets you confirm you have the right BBL and see whether the property has changed tax class recently, which often lines up with a change in use or ownership.

LLC-Owned Buildings

Most ACRIS deeds for rental buildings name an LLC as the grantee, not a person, because an LLC shields its members from personal liability. HPD registration is the way around that. Even when the ACRIS owner is an LLC, the registration statement still needs a real person's name as the head officer or individual owner, since HPD will not accept an entity name alone in that field.

Take that name, or the LLC's own name, to the New York Department of State's Corporation and Business Entity Search. It is free and needs no account. Search by the entity's name to confirm when it was formed and pull up its Articles of Organization, which can list an organizer or registered agent. The public database will not show every member of an LLC, since New York does not require that information to be filed, but a registered agent that recurs across several LLC filings often points to the same law firm or management company behind more than one building.

An LLC-owned building is not automatically worse than one owned outright. Most NYC rental property runs through an LLC for ordinary liability reasons. What matters is whether you can trace the name behind it, and HPD registration plus the state's business search is the most direct free path.

The LLC Transparency Act's Limited Reach

New York's LLC Transparency Act took effect January 1, 2026, and it sounds like it would solve the LLC problem outright. It does not, at least not yet, for the buildings most renters are researching. Governor Hochul vetoed a bill that would have expanded the law to cover domestic LLCs, meaning any company formed in New York or another US state, on December 19, 2025. As enacted, the law only requires a beneficial-ownership filing from LLCs formed outside the United States that are authorized to do business here. The overwhelming majority of New York rental property LLCs are formed in New York or Delaware, so they owe the state no new disclosure at all under this law.

That gap has become part of the public conversation about landlord accountability this year. Until the law covers domestic LLCs, HPD registration and the state's entity search remain the two tools that connect an LLC name to a person.

If ownership patterns matter to your decision beyond the name alone, compare the building's condition against others under the same management company, check whether the building is heading into foreclosure, and pull its current violations before you sign anything.

Frequently Asked Questions

Is ACRIS Free to Search?

Yes. Searching ACRIS and viewing or downloading scanned deeds, mortgages and other recorded documents costs nothing, and you do not need to create an account to use it. You only pay a fee if you specifically request a certified copy of a document, which the City Register's office provides for a formal purpose such as a court filing.

How Do I Find a Building's BBL?

Use the "Find Addresses and Parcels" search on ACRIS, or search the address at the Department of Finance's Property Tax Public Access portal at nyc.gov/nycproperty. Either one returns the Borough-Block-Lot number for the property, which you can then plug into the "Parcel Identifier" search on ACRIS for the most precise results.

Does HPD Registration Show the Real Owner Behind an LLC?

It requires a real person's name as the head officer or individual owner, even when the deed names an LLC. That name is not verified by HPD beyond the owner's own filing, so cross-check it against the LLC's Articles of Organization on the state's business database when you can.

Can I Find Out Who Owned a Building in the Past?

Yes. ACRIS lists every deed recorded against a property, not just the most recent one, so scrolling down the results shows prior owners along with the dates their deeds were recorded. Coverage goes back for decades on Manhattan, Brooklyn, Queens and Bronx parcels, and every result you find is free to view and download as a scanned document image.

What if the Building Is a Co-op or Condo?

Individual co-op shareholders and condo unit owners do not file their own HPD registration. The co-op board or condo board registers on behalf of the whole building instead, so a search will show the board or the managing agent rather than any one unit owner. ACRIS still shows the deed to your specific unit if you own a condo, and the stock certificate and proprietary lease for a co-op are held privately rather than recorded there.

Does the New York LLC Transparency Act Cover My Landlord's LLC?

Only if that LLC was formed outside the United States and is registered to do business in New York. LLCs formed in New York, Delaware or any other US state and territory are exempt from filing anything under the law as it currently stands.
