New York Notice and Mechanic Lien FAQs

Quick Answer
New York mechanics lien law under N.Y. Lien Law §§ 1-39 protects unpaid contractors, subcontractors, and suppliers. Key deadlines: file the Notice of Lien within 4 months of last furnishing on single-family residential (§ 10) or 8 months on commercial; commence foreclosure within one year of filing (§ 17); serve the Notice on the owner within 30 days (§ 11). NY does NOT require a preliminary notice — but Notice of Pendency (CPLR § 6501) on foreclosure is critical. National Lien & Bond files New York mechanics liens for unpaid contractors.

Who Has a Right to File a Mechanics Lien in New York?

In New York, a contractor, subcontractor, sub-subcontractor, laborer, or materials supplier that supplies materials to the owner, contractor, or subcontractor (but not to a sub-subcontractor) may file a mechanics lien concerning a private construction or improvement project. 

 

Do I Need to Provide a Preliminary Notice in Order to Protect My Mechanics Lien Rights in New York?

New York, unlike some other states, has no preliminary notice requirement when it comes to mechanics liens. There is no specific requirement in New York that any subcontractor or materials supplier involved in a project notify the owner or any other party in advance that the contractor or supplier is involved in the project.  

 

Must I Provide Any Other Information?

A subcontractor or material supplier should notify the project property owner of any unpaid amounts due or to become due within 90 days of when the work is completed or the material delivered. The notice should be sent:

  • registered or certified mail,
  • return receipt requested,
  • and may follow the format suggested by New York statute 770 ILCS 60/24.

While this notice is not necessary when the contractor has already identified the subcontractor or material supplier in the preliminary notice provided to the owner, there is no harm in giving this second notice when money is owed. 

In addition, the owner of the property affected by your mechanics lien may demand that you bring a lawsuit to enforce it. In that case, you have 30 days from when the demand is served on you to do so.

 

When Can I File a Mechanics Lien if I’ve Not Been Paid for Work or Materials?

Under New York law, a mechanics lien can be filed at any time while a project is still being worked on and up to 8 months from when the contractor, subcontractor, or materials supplier has completed their work or delivered the materials. This period is reduced to 4 months, with the project related to a single-family home.

 

Where Must I File the Mechanics Lien?

Mechanics liens must be filed with the clerk of the county where the project is located.

 

What Information Must a Mechanics Lien Contain?

New York law requires a mechanics lien to include very specific information, including:

  • The name and address of the party that is filing the lien
  • Their attorney’s information
  • The name of the property owner whose property is affected by the mechanics lien
  • The name of the party that the work was done for, or that the materials were supplied to
  • A description of the work that was performed or materials supplied and the agreed price for the work or materials
  • The unpaid amount that is owed
  • When the last work was performed, or materials were delivered
  • A detailed description of the property that is subject to the mechanics lien (such as street address or section, block, and lot number)

Failure to provide the required information can result in a mechanics lien being rejected by the county clerk or make the lien unenforceable.  

 

Are Public Projects Different? If So, How?

Many public projects in New York have payment bonds in place that are intended to guarantee payment to contractors, subcontractors, and suppliers involved in the project. Mechanics liens are typically unavailable in these cases, but claims can be made against the project’s payment bond. National Lien & Bond regularly helps clients involved in publicly-owned projects collect against these types of bonds.

In other public project cases, it may be possible to file a lien against the money the state appropriates for the project. There are different requirements for this type of lien, including where it’s filed and how long the lien is valid before a lawsuit is filed to enforce it. National Lien & Bond can also help you collect what you’re owed.

 

What Happens After I File My Mechanics Lien?

Two things happen once you file your mechanics lien with the local county clerk.

  • First is a lien against the project’s property for the total amount of the lien. This can make it more difficult for the property owner to use the property as collateral for loans, and in some cases, may breach the terms of existing loans.
  • Second, you can then sue to “foreclose” the lien to collect what you’re owed. The suit must be filed within one year after the notice of mechanics lien is filed with the county clerk; in some cases, this can be extended.

While a mechanics lien doesn’t guarantee you’ll be paid what you’re owed, it can be a powerful tool to help make that happen.

Frequently Asked Questions

What is the deadline to file a New York mechanics lien?

Under N.Y. Lien Law § 10, the New York Notice of Lien must be filed within 4 months after the last furnishing of labor or materials for single-family residential property, or within 8 months for commercial property and multi-family residential. The deadline runs from LAST furnishing, not from completion of the entire project — New York's deadline is generally claimant-friendly. The Notice of Lien must be filed with the County Clerk in the county where the property is located. Unlike California and Florida, New York does NOT require a preliminary notice — the Notice of Lien is the first formal step for sub-tier claimants.

Does New York require a preliminary notice before filing a mechanics lien?

No — New York does NOT require a preliminary notice (unlike California's 20-day Preliminary Notice under Cal. Civ. Code § 8200 or Florida's 45-day Notice to Owner under Fla. Stat. § 713.06). New York sub-tier claimants can proceed directly to filing a Notice of Lien within the 4-month residential or 8-month commercial deadline. However, New York DOES require the lien claimant to serve a copy of the filed Notice on the property owner within 30 days under § 11 — failure to serve within 30 days does not invalidate the lien but creates affirmative defenses. New York's lack of preliminary notice makes it one of the more claimant-friendly states.

What contents are required on a New York Notice of Lien?

Under N.Y. Lien Law § 9, a New York Notice of Lien must contain: (1) the name and residence of the lienor (claimant); (2) the name of the owner of the real property; (3) the name of the person by whom the lienor was employed or to whom the lienor furnished materials; (4) the labor performed or materials furnished and the agreed price or value; (5) the amount unpaid; (6) the time when the first and last items of work were performed; (7) a description of the property sufficient for identification, including a metes-and-bounds or block-and-lot reference. Defective Notices of Lien missing required content are unenforceable under New York law.

How long does a New York mechanics lien last before it expires?

Under N.Y. Lien Law § 17, a New York mechanics lien expires automatically ONE YEAR after filing UNLESS the claimant: (1) commences a foreclosure action; (2) files an order continuing the lien; or (3) the property owner serves a § 59 notice forcing earlier action. For single-family residential property, the deadline can be shorter. The one-year deadline is strict and cannot be tolled. Continuing the lien for an additional year requires a court order on a showing of cause — typically because settlement negotiations are ongoing. Most New York lien losses come from missed § 17 deadlines, not from denied claims on the merits.

What is a New York lien Notice of Pendency?

Under CPLR § 6501 and N.Y. Lien Law § 17, when a New York mechanics lien claimant commences a foreclosure action, they must file a Notice of Pendency (lis pendens) with the County Clerk. The notice puts the world on notice that the property is subject to pending litigation — purchasers and lenders take subject to the outcome of the lien foreclosure. The Notice of Pendency is one of the most powerful enforcement tools in New York construction-payment law because it effectively freezes the property from sale or refinance until the lien dispute is resolved. Failure to file the Notice of Pendency promptly weakens settlement leverage.

Can a property owner discharge a New York mechanics lien by bonding?

Yes — under N.Y. Lien Law § 19(4), a New York property owner can discharge a mechanics lien by filing a surety bond (or cash deposit) with the County Clerk in an amount equal to 110% of the lien (plus additional amounts for attorney's fees and costs in some cases). Once the bond is filed, the lien is automatically discharged from the property's title — but the unpaid contractor's recovery rights transfer to the bond. The contractor then pursues the bond instead of the property in the foreclosure action. Bonding off is common when the owner needs clear title for a sale, refinance, or new financing.

Are attorney's fees recoverable on a New York mechanics lien foreclosure?

Attorney's fees are not automatically recoverable under N.Y. Lien Law absent a contract provision or specific statutory fee-shifting. New York follows the American Rule by default. However, attorney's fees can be recovered when: (1) the subcontract or supply agreement contains an enforceable fee-shifting clause; (2) the New York Prompt Payment Act (Gen. Bus. Law § 756) applies and provides fee-shifting on late payments; (3) the lien is willfully exaggerated, in which case the claimant may face counter-recovery under § 39-a. Pre-work contract review to include fee-shifting clauses is one of the highest-ROI risk management practices for New York contractors.
