How to Find Property Owners in NYC

In a landscape as complex and competitive as the real estate market, knowing how to find property owners in NYC isn’t just useful — it’s essential. Whether you’re an investor pursuing off-market deals, a broker pitching a listing or a developer scouting strategic sites, direct access to the decision-maker — often via names, phone numbers, emails or mailing addresses — can turn a cold lead into a closed deal. 

But ownership is often hidden behind LLCs or holding companies, making it difficult to determine who really owns or controls a property. While public records offer free starting points for New York City property ownership research, subscription-based platforms can save time and reveal contact-level details that free tools often lack. 

In this article, we’ll break down the most effective free and paid methods for identifying real property owners in NYC and help you find the one that works for you best. 

1. NYC DOB BIS: Search by address and see current listed owner (likely LLC). 
2. NYC ACRIS: Search by address or BBL and access legal documents with possible real owner signatures. 
3. NY State Corporation & Business Entity Database: Search by LLC to find agents or cross-reference legal representation details.
4. On-site canvassing: Search for contact information in person and possibly locate building owner details in lobbies or entrances. 
5. Real estate data provider: Search for verified contact details of real owners in the PropertyShark database.

Let’s first explore four free methods methods for identifying real property owners in NYC.

The NYC Department of Buildings

The NYC Department of Buildings‘ (DOB) Building Information Search (BIS) is a useful starting point for property research across all five boroughs. By entering a property address, you can view data such as owner name, property classification, building applications and permits, violations, licensing and more. 

While the owner’s name listed is often the legal entity (LLC or corporation), in some cases, DOB filings include additional contact information like phone numbers, mailing addresses or the names of managing agents or filing representatives, all of which can help identify the actual individual or party responsible for the property. 

Tip: If the property is owned by an LLC, the DOB won’t show the real individual behind it, but it does give you a starting point to investigate further using other tools like ACRIS or the NYS Department of State. 

DOB Pros: 

• Free and easy to search by address 

• Shows current listed owner, usually the legal entity 

• May include additional clues in permits or filing documents 

• Offers building-level details like violations, permits and contractors 

DOB Cons:  

• Time-consuming 

• Typically identifies LLCs, not the beneficial (real) owners 

The NYC Automated City Register Information System 

The NYC Automated City Register Information System, more commonly known as ACRIS, is one of the most powerful free tools for uncovering ownership information in New York City. It allows users to search property records by address, borough/block/lot (BBL) or document type, among other options. Through ACRIS, you can access legal documents such as deeds, mortgages or financial statements, many of which can include the names and signatures of individuals tied to an LLC or corporation. 

NYC ACRIS is a great way to cross-reference LLCs found in the DOB’s BIS and verify the accuracy of the information, to follow the right track towards uncovering the real owner. 

Tip: Even if the property is owned by an LLC, the signatory on the deed or mortgage document is often a real person, offering a valuable lead for further outreach or verification. Also, you can make in-person appointments to research, review and print property records — just keep in mind that bookings are limited to one hour. 

ACRIS Pros: 

• Completely free to use 

• Provides official documents like deeds and mortgages 

• May show signatures or names of individuals tied to LLCs 

• Useful for historical ownership and sales data 

ACRIS Cons: 

• Doesn’t clearly identify beneficial (real) owners 

• Requires time to manually search and interpret documents 

• Doesn’t cover all boroughs, since Staten Island uses a different system 

The New York State Department of State’s Corporation & Business Entity Database 

Once you’ve identified an LLC through ACRIS or the DOB, you can search for it in the New York State Department of State’s Corporation & Business Entity Database. This database provides key filing details about the LLC, including: 

• The registered agent 

• Filing date 

• Service of process address 

• Occasionally, the name of the person who filed or manages the LLC 

While it doesn’t always reveal beneficial ownership directly (like the owner’s name or phone number), this tool is excellent for cross-referencing and locating contacts and addresses for an owner or their legal representative. 

Tip: Check the Articles of Organization for names of organizers or members who may be tied to other properties. These may sometime be linked externally.  

NYS Corporation & Business Entity Database Pros: 

• Free and useful for looking up LLCs 

• Shows service of process address, registered agent and filing date 

• May include organizer or filer’s name in formation documents 

NYS Corporation & Business Entity Database Cons: 

• Often lists generic agents or law firms, not the true owner 

• Does not confirm property-specific ownership 

• Lacks contact info like phone numbers or emails 

• Time-consuming 

On-Site Canvassing & Building Signage 

Sometimes, the most effective and overlooked way to identify property owners is simply visiting the property in person. On-site canvassing can reveal: 

• Building management contact information posted in lobbies or entrances 

• Superintendent or building manager names and phone numbers 

• Mailboxes labeled with individual or business names 

• Property intercom listings 

While this method requires time and footwork, it can be a valid avenue of research when public databases fall short, especially for smaller residential or mixed-use properties where an owner may be more directly involved in day-to-day operations. 

Tip: Strike up a brief conversation with building staff or neighbors. Local knowledge can often point you in the right direction more quickly than hours of online digging. 

On-Site Canvassing Pros: 

• Can uncover information not available online 

• Useful for smaller or owner-managed buildings 

• May reveal superintendent, building manager, or mailbox names 

• Helpful for casual conversation or lead generation 

On-Site Canvassing Cons: 

• Time-consuming and labor-intensive 

• Not always practical for out-of-town or large-scale research 

• May still require follow-up with public records to verify 

Now let’s explore a subscription-based method for finding real NYC owners.

PropertyShark: A Faster, More Reliable Way to Uncover Real Owners  

While free tools like ACRIS and DOB are helpful, they often require piecing together scattered information and may not reveal the person behind an LLC. For instance, an LLC can be owned by another LLC, maybe even one registered in another state, which will prompt the search to another state-level public source.   

PropertyShark offers a more efficient and complete solution, cutting through all that manual work and instantly uncovering the real owners, making it a go-to platform for real estate professionals who want to learn how to find property owners in NYC. 

What Sets PropertyShark Apart: PropertyShark Pros 

• Unmasks LLCs: Shows the actual individuals behind LLC-owned properties which most free databases don’t do. 

• Includes verified contact info: Get access to phone numbers, emails and mailing addresses for property owners and decision-makers. 

• All-in-one property reports with detailed profiles that include: 
  • Ownership history 
  • Zoning and FAR 
  • Tax assessments and liens 
  • Building violations and permits 
  • Sales comps and transaction history. 

Unlike free tools that require checking multiple databases and manually connecting the dots, PropertyShark streamlines the research process by consolidating all relevant information into one platform. It eliminates the need to bounce between ACRIS, the Department of Buildings and the Department of State, saving users valuable time.  

Most importantly, PropertyShark offers verified ownership and contact details that free resources typically don’t provide, allowing real estate professionals to reach the right person faster and with greater confidence. 

How to Identify Property Owners in the PropertyShark Database 

1. Search for the address of your choice, then go to the Contacts tab where you will find the registered owner (possibly an LLC), but also the real owner behind the LLC, along with their contact details, including email addresses and phone numbers. You can also see contact details from building permits, as well as the registered agents. 

2. Click on the owner’s name if you want to access their entire portfolio and assess more of their properties. This search will provide you with a list of properties currently or previously owned as well as any properties they were associated with in another real estate role other than owner. To take your research one step further, read this guide on how to build property owner lists. 

3. You can also deep-dive owner information by using the Deep Owner search function: Just enter their name in the search box under the Owners tab. This type of search is useful when you already know or have uncovered the owner’s name, allowing you to cross-reference information and access an owner’s entire portfolio, including property reports and contact details.  

You will also have access to information regarding the building class and square footage, the time held by the respective owner and the full property report.

Choosing the Right Real Owner Research for You

Finding the real owner behind a New York City property can be both a strategic advantage and a logistical challenge. Free tools like ACRIS, DOB and the NY Department of State offer valuable starting points for research, especially for those willing to invest time in cross-referencing and digging into public records.
