Navigating New York City real estate records used to mean waiting in crowded municipal offices. Today, the Automated City Register Information System (ACRIS) puts decades of city land records online. Whether you're checking a prospective landlord, verifying a deed, or preparing property filings, knowing how to work the system saves time and prevents costly errors.
Property ownership in New York City is tied to tax lots rather than mailing addresses alone. This guide breaks down how to search records efficiently, interpret what you find, and handle document filings through the NYC Department of Finance platform.
Navigating the ACRIS Database
The system indexes property records for Manhattan, Queens, Brooklyn, and the Bronx dating back to 1966. Staten Island records are handled differently through the Richmond County Clerk, so ACRIS doesn't cover them.
When you open the main search portal on the NYC Department of Finance ACRIS site, you'll see several paths for finding information. Choosing the right path depends on the details you have on hand.
Searching by Property Address
If you know the street address, use the parcel identifier option.
- Select the correct borough.
- Enter the street number and name.
- If the system prompts you for a Borough, Block, and Lot (BBL) number and you don't know it, use the built-in address lookup tool to find it.
Every property in the city has a unique BBL code. For condos, you'll also see a specific unit number attached. Co-ops generally don't appear in ACRIS individual unit records because co-op shares are treated as corporate shares rather than direct real property. For co-ops, you have to contact the building management or board.
Searching by Party Name
You can look up transactions by entering an individual or corporate name. Enter last names first for individuals, or the exact corporate name for LLCs and businesses. This method helps trace what properties a specific developer or landlord has bought or sold over time. Keep in mind that common names will yield hundreds of unrelated results, so you'll need to filter by date or document type.
Understanding Document Types
Once you pull up a property's history, you'll face a long list of codes and document categories. Knowing what these documents mean prevents misinterpretations.
- Deed (DEED): Confirms who holds the title and usually shows the purchase price. Look at the document date versus the recorded date to spot delayed filings.
- Mortgage (MTG): Details how much debt an owner took on and names the lender.
- Agreement (AGMT): Shows easements, restrictions, or special terms tied to the parcel.
- Satisfaction of Piece or Release: Indicates that a mortgage or lien has been paid off.
Filing and Recording Documents Electronically
Beyond looking up history, professionals use the platform to record new transactions. Submitting paperwork electronically requires strict adherence to technical standards to avoid rejection by the City Register.
Preparing Your Submission
You must create digital tax forms and cover pages within the system before uploading. If you're managing a flip transaction where a property transfers rapidly from party A to B and then to C, you must file two separate electronic tax transactions and cover pages.
Technical Rules for PDF Uploads
The City Register converts uploaded PDF files into public record images. If your files don't meet strict formatting criteria, your filing will stall:
- Pages must measure no larger than 11 by 17 inches.
- Files must be scanned in pure black and white; color elements will not convert properly.
- Remove all document layers and flatten the PDF before uploading.
- Disable any security features or passwords that prevent conversion.
- Keep scans clean at a standard resolution of 300 DPI.
Pay any required recording fees and transfer taxes directly via eCheck or credit card. Online payments cannot be split across multiple bank accounts, so ensure your funding source has adequate clearance.
Common Mistakes to Avoid
Filers and researchers often make avoidable errors that disrupt transactions or waste hours of investigation.
- Ignoring the BBL: Searching only by street name can miss historic filings under old lot divisions. Always verify the current BBL on official tax maps.
- Using Unapproved Third-Party Portals: Stick strictly to official city domains. Independent lookalike sites often add service fees or fail to update records in real-time.
- Submitting Mixed Formats: If you start a transaction on paper, you must finish it on paper. You can't mix electronic submissions and paper drop-offs for the same single filing event.
Frequently Asked Questions
Can I look up co-op apartment ownership on ACRIS?
No. Co-ops are corporate shares rather than direct real property, so individual purchases don't generate public deeds in this database. You must check with the building's managing agent.
Are historical records before 1966 available online?
No. Records predating 1966 require visiting the physical Land Records Research Library or municipal archives.
Is there a fee to download property deeds?
Downloading scanned copies of deeds, mortgages, and other public instruments is completely free. You only pay fees when you record new documents or request certified copies.
Why was my e-recording rejected?
Rejections usually stem from formatting issues, such as color scans, unflattened PDF layers, or mismatched transfer tax amounts on your cover page. Check your submission status dashboard for specific error notes from the City Register.
