Over 7 million property documents are publicly searchable through ACRIS NYC, the city's free online portal for deeds, mortgages, liens, and satisfaction records dating back to 1966. As a Licensed Associate Broker with Keller Williams NYC, I use ACRIS on nearly every transaction to verify ownership history, confirm mortgage balances, and flag potential title issues before they derail a deal. In my 25+ years closing transactions across Manhattan, Brooklyn, and Queens, ACRIS has saved my clients from costly surprises more times than I can count.
Whether you are a first-time buyer researching a condo or co-op, an investor evaluating a multi-family property, or a seller preparing to list, understanding ACRIS NYC is one of the most valuable skills you can develop. This guide walks you through exactly how to use it.
What Is ACRIS NYC?
ACRIS stands for the Automated City Register Information System. It is operated by the New York City Department of Finance and provides free, public access to property records filed with the City Register. Every real property transaction in NYC, with the exception of most co-op share transfers in some boroughs, gets recorded here.
The system covers all five boroughs: Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. You can access ACRIS at a836-acris.nyc.gov directly from any web browser, no account or login required.
What Records Can You Find on ACRIS?
| Document Type | What It Tells You | Why It Matters |
|---|---|---|
| Deed | Current and previous owners, sale prices | Confirms legal ownership chain |
| Mortgage | Lender name, loan amount, date | Shows existing debt on the property |
| Satisfaction of Mortgage | Proof a mortgage has been fully paid off | Confirms no outstanding liens from prior loans |
| UCC Filing | Personal property liens (often co-op shares) | Critical for co-op buyers to verify |
| Lis Pendens | Pending lawsuits involving the property | Red flag for buyers, indicates legal disputes |
| Tax Lien | Unpaid property taxes | Must be resolved before a clean title transfer |
| Memorandum of Contract | Recorded purchase contract | Shows the property is under contract |
Step-by-Step: How to Search ACRIS NYC
Step 1: Go to the ACRIS Portal
Navigate to a836-acris.nyc.gov/DS/DocumentSearch/Index. You will see several search options. The two most useful are "Parcel Identifier" (borough, block, and lot) and "Address."
Step 2: Search by Address
Click "Address" in the left menu. Select the borough, enter the street number and street name, and click "Search." ACRIS will return all recorded documents associated with that property. For condos, you will also need the unit number. For co-ops, ACRIS may not have individual unit records since co-op transfers are often recorded differently.
Step 3: Search by BBL (Borough, Block, Lot)
If you know the BBL number (available on NYC's property tax bill or the Department of Finance website), select "Parcel Identifier." Enter the borough code (1=Manhattan, 2=Bronx, 3=Brooklyn, 4=Queens, 5=Staten Island), then the block and lot numbers. This method is the most precise and avoids address formatting issues.
Step 4: Review the Results
Results appear in reverse chronological order. Each row shows the document type, date recorded, and parties involved. Click any row to view the full scanned document. I recommend checking deeds first to verify the ownership chain, then mortgages to understand the existing debt picture.
Pro Tip: Cross-Reference with DOF Property Tax Records
ACRIS shows recorded documents, but the NYC Department of Finance property tax portal shows the assessed value, tax class, and any exemptions (like STAR or 421-a abatements). I always check both when doing due diligence on a property. The DOF portal is at propertyinquiry.finance.nyc.gov.

How Buyers Should Use ACRIS NYC
Before making an offer on any NYC property, I advise my clients to pull the ACRIS records. Here is what to look for:
- Ownership verification: Confirm the seller is actually the recorded owner. Deed records show every transfer since 1966.
- Outstanding mortgages: Check whether any mortgages lack a corresponding satisfaction record. If a mortgage from 2015 was never officially satisfied, it creates a cloud on title.
- Liens and judgments: Tax liens, mechanic's liens, and lis pendens can all affect your ability to get clear title.
- Sale price history: Deed transfer records often include the sale price, letting you see what the seller originally paid. This is valuable context for your offer strategy.
How Sellers Should Use ACRIS
Sellers benefit from checking ACRIS before listing. You want to confirm that any old mortgages show a satisfaction of mortgage on record. I have seen closings delayed by weeks because a lender from a refinance 10 years ago never filed the satisfaction. Catching this early lets your attorney resolve it before it becomes a closing issue.
Sellers should also verify their recorded deed matches their current legal name. Name changes from marriage or other reasons sometimes create discrepancies that require a corrective deed filing. If you are preparing to sell, my seller consultation page covers the full checklist.
ACRIS Limitations to Know
ACRIS is powerful, but it has blind spots. Co-op transfers in some boroughs may not appear because co-op sales involve the transfer of shares and a proprietary lease rather than a deed. For co-op due diligence, you will need to request information directly from the building's managing agent. Read more about the differences in my co-op vs. condo guide.
ACRIS records go back to 1966 for most boroughs, but earlier documents require a visit to the City Register's office. The search interface can also be finicky with address formatting, so using BBL numbers is almost always more reliable.
ACRIS NYC for Investors
Real estate investors use ACRIS to research properties before bidding. You can see every mortgage, refinance, and transfer associated with a property. If you are evaluating a multi-family building, ACRIS reveals whether the current owner has been refinancing aggressively (which may signal financial stress) or whether the property has been in the same hands for decades (potentially undervalued).
For studio and one-bedroom condo investors, ACRIS confirms the original offering plan sponsor's deed and whether any unsold sponsor units remain, which affects building governance and financing eligibility.
Bottom Line
ACRIS NYC is one of the most underused free tools available to NYC real estate buyers, sellers, and investors. Taking 15 minutes to search a property's records can reveal ownership history, outstanding debt, liens, and legal disputes that directly affect your transaction. I pull ACRIS records on every deal I handle at Keller Williams NYC, and I recommend you do the same. If you need help interpreting what you find, get in touch and I will walk you through it.
