Why You Need to Know Who Your Landlord Is
Your landlord controls your heat, your repairs, your security deposit, and every lease renewal for as long as you live in the building. If something goes wrong, the first question is always the same: who do I actually contact, and who is legally responsible?
In NYC, that question is harder than it should be. About 70% of NYC rental buildings are owned by LLCs, which are legal shells that protect the real owners from liability. The LLC name on your lease might be a six-layer corporate stack with a registered agent in Delaware. Your "landlord" might be a fund manager you've never heard of.
The good news: every layer is public record. NYC has four free portals that, taken together, reveal the complete picture in about five minutes.
The 4 Portals You Need
1. ACRIS — The Deed of Record
ACRIS (Automated City Register Information System) is the NYC Department of Finance portal at a836-acris.nyc.gov. It tracks every property deed, mortgage, lien, and transfer in NYC back to 1966. This is the single most authoritative source for who actually owns a building.
How to search:
- Go to
a836-acris.nyc.gov - Click "Document Search" → "Search by Address"
- Enter borough, street number, and street name
- Sort results by "Document Date" descending
- Open the most recent "DEED" document
- Note the "Grantee" field — that's the current owner
💡Shortcut: Use the BBL
If you know the building's Borough-Block-Lot (BBL), you can search ACRIS directly by BBL which is faster than address. Find the BBL on NYC Digital Tax Map or by searching the address on PLUTO data.
2. HPD Online — The Registered Managing Agent
NYC law requires all residential buildings with 3+ units to register annually with HPD (Housing Preservation & Development). The registration must include a managing agent's name, phone number, and mailing address — this is your official legal contact for repairs, complaints, and lawsuits.
How to search:
- Go to
hpdonline.nyc.gov - Click "Building/Block Search"
- Enter the building address
- Click into the building profile
- Look for the "Registration" tab or section
- Note the Head Officer, Managing Agent, and Owner contact fields
⚠️Unregistered Building?
If HPD shows "No Registration on File" or the registration is expired, the landlord is violating NYC law. File a 311 complaint for "Failure to Register" — HPD will investigate and fine the owner.
3. NY Department of State — The People Behind the LLC
If ACRIS shows that the owner is an LLC or corporation, you need one more step to find the actual humans. Every LLC that does business in New York must register with the NY Department of State and list a registered agent for service of process.
How to search:
- Go to
appext20.dos.ny.gov/corp_public/corpsearch.entity_search_entry - Enter the LLC name exactly as shown on the ACRIS deed
- Click the entity name to see the full record
- Note the registered agent, filing date, and service address
- Look for any cross-referenced entities or filing history
The registered agent is legally required to accept service of lawsuits on behalf of the LLC. That doesn't mean they're the beneficial owner — but it gives you a real name and address to work with.
4. JustFix Who Owns What — The Portfolio Map
JustFix Who Owns What is a free community tool that cross-references HPD registration data to map landlord networks. If your LLC is part of a larger portfolio, this is where you find out. It's especially useful for identifying professional landlords with patterns of violations across multiple buildings.
How to search:
- Go to
whoownswhat.justfix.org - Enter any NYC building address
- Review the "Portfolio" tab for all related buildings
- Check the "Timeline" tab for ownership changes and violation patterns
- Use the map to see geographic concentration
Skip All Four Portals
DwellCheck aggregates ACRIS deeds, HPD registration, LLC records, and portfolio mapping into a single report — plus violations, complaints, and building health data your landlord hoped you wouldn't see.

Signs of a Professional (Usually Fine) Landlord
- HPD registration is current and up-to-date
- Managing agent is a known property management company
- LLC has been stable for 3+ years
- Single building or small portfolio (1-10 buildings)
- Google search returns business pages, not complaints
Signs of a Predatory or Negligent Landlord
- HPD registration expired, missing, or recently filed
- Multiple LLCs in a complex ownership stack (shell game)
- Portfolio with 50+ buildings and chronic HPD violations
- Registered agent at a P.O. box or virtual office

- Recent sale to an out-of-state buyer
Yellow Flags (Investigate Further)
- Building sold in the last 12 months — new owner behavior unknown
- Deed transfer between related LLCs — may indicate restructuring
- Single owner but multiple business addresses
- LLC name that's intentionally generic or obscure
Check Landlord — Different From Looking Them Up
This guide covers the first step: who is your landlord. The next step is evaluating what kind of landlord they are — their violation history, 311 complaints, housing court record, and reputation.
That's covered in our companion guide: How to Check Your Landlord in NYC. Together, the two guides give you the complete picture: identity plus track record.
Frequently Asked Questions
1How do I find out who owns my NYC apartment building?
Search ACRIS (a836-acris.nyc.gov) by address. The most recent deed shows the current owner. If the owner is an LLC (which happens in ~70% of NYC rental buildings), cross-reference the LLC name on the NY Department of State business entity database (appext20.dos.ny.gov) to find the managing members. HPD registration at hpdonline.nyc.gov also lists the managing agent, which is often the best contact for repairs and complaints.
2What if my landlord is an LLC?
LLCs are legal and very common in NYC for liability protection. To find the real people behind an LLC: (1) search the LLC name on the NY Department of State business entity database, (2) look at recent deeds filed on ACRIS which sometimes list individual signatories, (3) use JustFix Who Owns What (whoownswhat.justfix.org) which aggregates LLCs owned by the same people, and (4) Google the LLC name for news articles, lawsuits, or published business filings.
3What is JustFix Who Owns What?
JustFix Who Owns What is a free tool at whoownswhat.justfix.org that lets you search any NYC address and see all other buildings owned by the same landlord or LLC network. It uses HPD registration data to map corporate relationships, which is extremely useful for identifying portfolio landlords and understanding if your building is part of a larger operation with a pattern of violations.
4How do I contact my landlord if HPD only shows a managing agent?
In NYC, buildings with 3+ residential units are legally required to register a managing agent with HPD. That agent is your official legal contact for repairs, complaints, and service of legal notices. If the HPD registration is out of date or missing, you can file a 311 complaint for "Failure to Register" which triggers an HPD investigation.
5What is ACRIS and what does it show?
ACRIS (Automated City Register Information System) is the NYC Department of Finance portal at a836-acris.nyc.gov that tracks all property deeds, mortgages, liens, and transfers back to 1966 (and earlier for some documents). You can search by address, borough-block-lot, or party name. The most useful documents are deeds (who owns it), mortgages (financial pressure signals), and liens (tax or mechanics liens indicating distress).
6How long does it take to look up a landlord?
With all four portals open (ACRIS, HPD Online, NY DOS Business Entity Search, and JustFix Who Owns What), most landlord lookups take 5-10 minutes. The limiting factor is usually ACRIS, which can be slow. DwellCheck aggregates this data automatically so you can skip the manual research entirely.
7Can I look up a landlord before I sign a lease?
Absolutely, and you should. All NYC landlord and building ownership records are public. A landlord cannot legally refuse to rent to you for researching their track record. In fact, a landlord who reacts defensively or hostile to basic ownership questions is itself a red flag. Research before you sign is standard due diligence.
8Is it free to look up NYC landlord information?
Yes, all of the primary lookups are free: ACRIS, HPD Online, NY DOS Business Entity Search, 311 records via NYC Open Data, and JustFix Who Owns What. DwellCheck aggregates these into a single paid report ($2.99) if you want the time savings, but every raw source is publicly accessible for free.
9What if the landlord records are wrong or out of date?
NYC records update at different cadences. ACRIS updates within 24-48 hours of deed filings. HPD registration must be renewed annually but landlords sometimes let it lapse. NY DOS LLC records update when business filings are submitted. If you find conflicting information, cross-reference with recent 311 complaints at the address (which often list the actual contact person) and Google the LLC name for current news coverage.
10Can I sue a landlord if I only know the LLC name?
Yes. NYC law requires LLCs that own residential property to register with HPD and provide the name of the managing agent or a principal who can be served with legal papers. If you need to sue, an attorney can serve the LLC through its registered agent (usually listed on NY DOS) or through the HPD-registered managing agent. Failure to maintain current HPD registration does not shield the owner from lawsuits.
The Bottom Line
In NYC, "who is my landlord" has a real answer. It's usually buried under an LLC, but the path to find it is public, free, and takes about five minutes end-to-end. ACRIS for the deed, HPD for the managing agent, NY DOS for the LLC principals, JustFix for the portfolio map.
If your landlord objects to any of this research, that itself is a signal. Public records are public for a reason.
