Where NYC liens actually live (five different systems)

The reason “how to find liens on a property in NYC” has no one-line answer is that the city files different kinds of liens in different places that don’t talk to each other. A property can be perfectly clean in ACRIS and still be ninety days from having its tax debt sold — or current on taxes and carrying a six-figure ECB judgment no title company will insure over.

Here is the actual map:

One category sits off to the side: federal tax liens (IRS) are filed in ACRIS’s personal-property records against the taxpayer’s name, not the property’s BBL — a name-based index that address-based tools, including ours, don’t reach.

How to search each one free (manual method)

Every system above has a free public interface. Here is the search path for each.

1. DOF tax lien sale list. The Department of Finance publishes the at-risk list on its property lien sales page and in NYC Open Data. Search by borough-block-lot (BBL). A property on the list isn’t foreclosed — it’s in a countdown: DOF mails 90-, 60-, 30-, and 10-day notices before selling the debt to an authorized trust, and owners can pay or enter a payment agreement to come off the list at any stage. For how the sale itself works, see our tax lien sale list guide.

2. ACRIS. The city’s recording system (about page; search interface) holds documents recorded against real property in Manhattan, the Bronx, Brooklyn, and Queens (Staten Island records sit with the Richmond County Clerk). Use Document Search → by Parcel Identifier, enter the BBL, and scan the document types: MTGE (mortgage), SAT (satisfaction), ASST (assignment), LOCC (condo common-charge lien), TLS/ATL/AMTL (tax lien sale certificates), DTL (tax-lien discharge), RTXL (estate-tax-lien release). An open mortgage with no matching satisfaction, or a common-charge lien with no termination, is the pattern you’re looking for.

3. ECB/OATH judgments. Search unpaid violation balances on CityPay’s ECB lookup by address or ticket number; OATH is the tribunal behind them. These balances matter far beyond their face amount — see the Local Law 153 section below.

4. County Clerk / NYSCEF. Mechanic’s liens are filed with the County Clerk of the borough where the property sits, and lis pendens / foreclosure filings live in the state court system, searchable through NYSCEF by party name or index number. This layer is court data, not city data — not in ACRIS and not in our lookup — and it’s where pre-foreclosure activity first becomes visible.

5. DEP water billing. Water and sewer arrears only reach the lien-sale list after they age past DOF’s thresholds. To see the current balance earlier, use DEP’s online account portal — full detail generally requires the account holder’s access, which is why attorneys request a bill history from the seller before closing.

The one-query shortcut

Three of the five systems — the lien-sale list, ACRIS recorded liens, and ECB judgment balances — can be checked in a single free query.

🔎 Check a property’s lien record — free

→ Look up any NYC address

Ask about any address and we’ll return, for that BBL: tax lien sale list appearances (2019–2025 cycles, notice stage, water-only flag), recorded ACRIS documents — mortgages, satisfactions, common-charge liens, tax lien certificates and discharges — and open ECB/OATH judgment balances, from 20+ official NYC datasets across 9 city agencies. No signup for your first queries.

What it does not cover, stated plainly: federal tax liens (ACRIS personal-property records), mechanic’s liens (County Clerk), lis pendens and foreclosure filings (NYSCEF), and water arrears that haven’t reached the lien-sale list. And it is not a title search — see below.

Do ECB violations become liens? (Local Law 153)

Yes — unpaid ECB/OATH judgments can be entered as tax liens against the property under Local Law 153 of 2017, and for small buildings the conversion is automatic with no dollar minimum.

The mechanics: when an owner doesn’t pay or doesn’t appear on an ECB violation, the penalty becomes a default judgment enforceable for eight years. Local Law 153 lets DOF convert that judgment into a tax lien on the real property itself:

• Private dwellings and buildings with three or fewer dwelling units: conversion is automatic, with no minimum — a single unpaid $1,000 judgment can become a lien on a rowhouse.
• Buildings of 6–19 units: converts at $30,000+ in unpaid judgments.
• Buildings of 20+ units: converts at $60,000+.

Why this matters more than the dollar amounts suggest: title companies routinely refuse to insure over open ECB judgments — so in practice the balances must be satisfied at or before closing whether or not DOF has formally entered the lien yet. An unpaid ECB balance is a lien-in-waiting, and it attaches to the BBL, not the person who earned it: buy the building, inherit the exposure. Our DOB & ECB violations lookup covers this record in depth.

Condo & co-op common-charge liens

When a condo owner stops paying common charges, the board can record a lien against the unit in ACRIS — document type LOCC — and there are 28,800+ of them on record. This is the lien class almost every “free lien search” tool skips, and a building showing many of them is a red flag in itself — a board that can’t collect common charges is a board deferring maintenance.

The search logic differs sharply by ownership type:

• Condos: each unit is real property with its own BBL, so a common-charge lien is a recorded ACRIS document (LOCC), released by a termination (TOLCC). Our free lookup returns both for any unit — an LOCC with no matching termination means the debt is likely still open.
• Co-ops: a co-op apartment is not real property — you own shares in the corporation plus a proprietary lease. Unpaid maintenance is typically enforced against the shares through UCC filings in ACRIS’s personal-property records, a name-indexed system that address-based real-property searches (including ours) don’t cover. For a co-op, the reliable moves are asking the managing agent for an arrears letter and having your attorney run a UCC search on the seller — while the building’s own BBL can still be checked normally for the underlying mortgage, tax status, and ECB record.

What a lien search cannot tell you

A free lien search — this page’s manual method and our one-query version alike — is a screening tool, not a clearance. It cannot substitute for a title search, and anyone who tells you otherwise is selling something.

What stays invisible to public-facing lookups, ours included:

• Court-side filings: mechanic’s liens, lis pendens, and foreclosure actions live at the County Clerk and in NYSCEF, not in ACRIS — the single most consequential gap for anyone assessing distress.
• Federal tax liens: filed against the owner’s name in ACRIS personal-property records; a BBL search will never surface them.
• Name-and-indexing problems: liens filed against prior owners, misspelled names, or the wrong lot — the errors a professional title examiner is paid to catch.
• Unrecorded interests: unrecorded easements, boundary issues, heirs’ claims, and defects in old instruments.
• Timing: public datasets lag. A lien recorded yesterday, or a judgment entered this morning, may not appear anywhere yet.

The right mental model: use free lien searches before you spend money — to decide whether a deal is worth pursuing and what to price in. Then, before closing, your attorney orders a professional title search and title insurance regardless of how clean the free checks looked. Our due-diligence guide covers where a lien check sits in the full pre-offer workup.

FAQ

How can I find out if there is a lien on a property in NYC for free?

Check four free official sources: the Department of Finance tax lien sale list (unpaid taxes and water charges at risk of sale), ACRIS (recorded mortgages, condo common-charge liens, tax lien certificates), OATH/ECB via CityPay (unpaid judgment balances that become liens under Local Law 153), and the borough County Clerk or NYSCEF (mechanic’s liens and lis pendens). No single site shows all of them. Our free chat covers the first three in one query per address; the County Clerk layer you must search separately.

Can I search for liens on ACRIS by address?

Yes — ACRIS lets you search recorded documents by address or borough-block-lot (BBL) under Document Search, then filter by document class. Liens and related instruments show up as specific document types: mortgages (MTGE), satisfactions (SAT), condo common-charge liens (LOCC) and their terminations (TOLCC), tax lien sale certificates (TLS/ATL/AMTL), tax-lien discharges (DTL), and estate-tax-lien releases (RTXL). The catch is that ACRIS only holds what gets recorded there: mechanic’s liens, lis pendens, and most court judgments live at the County Clerk instead, and federal tax liens sit in ACRIS’s separate personal-property records.

Do unpaid ECB or DOB violations become liens on the property?

Unpaid ECB/OATH judgments can. Under Local Law 153 of 2017, the City can enter an unpaid ECB judgment as a tax lien against the property — automatically, with no dollar minimum, for a private dwelling or any building with three or fewer dwelling units; at $30,000+ in unpaid judgments for buildings of 6–19 units; and at $60,000+ for buildings of 20 or more units. ECB judgments remain enforceable for eight years, and title companies routinely refuse to insure over open judgments. A standard DOB violation with no ECB penalty attached does not itself become a lien.

How do I search for liens on a co-op or condo in NYC?

They work differently. A condo unit is real property, so unpaid common charges become a recorded lien in ACRIS — document type LOCC — against the unit’s own BBL; there are 28,800+ of these on record, and our free lookup returns them. A co-op apartment is not real property — you own shares plus a proprietary lease — so a co-op’s claim for unpaid maintenance is typically enforced against the shares through UCC filings in ACRIS’s personal-property records, which address-based real-property searches (including ours) do not cover. For a co-op, ask the managing agent for arrears and run a UCC search on the shareholder.

Is a lien search the same as a title search?

No. A lien search — this page, or any free public-records check — shows you what the public systems currently display for a property. A title search is a professional examination of the chain of title, backed by title insurance, that catches what public-facing lookups miss: indexing errors, liens filed against prior owners under name variations, unrecorded interests, and defects in old instruments. Use free lien searches to decide whether a deal is worth pursuing and what to negotiate; before closing, your attorney orders a full title search regardless.

How do I check if a property is on the NYC tax lien sale list?

The Department of Finance publishes the at-risk list before each sale and mails owners a sequence of 90-, 60-, 30-, and 10-day notices; the list is on DOF’s lien sale page and in NYC Open Data. Our free chat checks it for you: ask about any address and we’ll report whether its BBL appears in the 2019–2025 sale cycles — 264,142 list entries — including the notice stage it reached and whether the debt was water-only. See our tax lien sale list guide for how the sale itself works.
