NYC Mechanic's Lien Rights and Process
What is a mechanic's lien in NYC?
A mechanic's lien is a legal claim filed against real property by a contractor, subcontractor, or material supplier who performed work or supplied materials that improved the property and has not been paid. New York's Lien Law gives these parties the right to "lien" the property — recording a claim against the title that must be addressed before the property can be sold or refinanced free and clear. A mechanic's lien can be a powerful tool for unpaid contractors to force payment.
What is the deadline to file a mechanic's lien in NYC?
Filing deadlines depend on the property type. For private buildings (not public or government work): 8 months from the last date of work (for one- and two-family homes used solely for residential purposes, the period is 4 months). For public improvements (streets, sewers, etc.): 30 days from completion of the contract. These deadlines are strict — missing the filing window permanently extinguishes the lien right. Track the "last date of work" carefully from the moment a project starts going sideways.
How do I file a mechanic's lien in NYC?
File a Notice of Mechanic's Lien with the NYC City Register (for Manhattan, Brooklyn, Queens, and Bronx) or the Staten Island County Clerk. The notice must include: the property's legal description (including block and lot), the amount claimed, the name of the owner, the lienor's name and address, a description of the work performed or materials supplied, and the period during which the work was performed. The filing must be made within the applicable deadline. Consult an attorney — defects in the filing can invalidate the lien.
What is a Notice of Lending and how does it affect lien rights?
A Notice of Lending is a document filed by the construction lender in the NYC City Register notifying the public that a lender is financing the project. Once a Notice of Lending is filed, subcontractors and suppliers must file a Notice to Lender within 5 days of first furnishing labor or materials on the project to protect their lien rights. Failure to file a Notice to Lender when required may limit the subcontractor's lien priority against the lender. On any financed project, always check whether a Notice of Lending has been filed.
What is the difference between a mechanic's lien and a judgment lien?
A mechanic's lien is filed directly against the real property by a party who performed work at that property — it's pre-judgment. A judgment lien arises when a party obtains a court judgment and files it in the county clerk's office, creating a lien against all real property the debtor owns in that county. Mechanic's liens must be enforced (foreclosed) within a specified period, while judgment liens have longer survival periods. Both appear in title searches and must be resolved before a clean sale.
How does a property owner discharge a mechanic's lien?
Options to discharge: (1) Pay the lienor — the lienor then files a lien satisfaction in ACRIS; (2) Bond over the lien — obtain a surety bond in the amount of the lien (or 110% of the lien), file the bond with the court, which releases the lien from the property (the contractor's claim then runs against the bond, not the property); (3) Contest the lien in court — if the lien amount is improper or the filing is defective, petition to discharge it; (4) The lien expires if the lienor doesn't foreclose within the required period.
How does a contractor enforce a mechanic's lien?
After filing, the contractor must commence a lien foreclosure action within one year (for private improvement projects) or risk the lien expiring. Foreclosure is a court action in NYS Supreme Court seeking a judgment to sell the property to satisfy the lien. Lien foreclosures are slow and expensive — typically 2-4 years. In practice, most mechanic's lien disputes settle before foreclosure, often after significant negotiation. The lien serves primarily as leverage to compel payment.
Can a subcontractor file a lien even without a direct contract with the owner?
Yes. Under New York's Lien Law, a subcontractor, sub-subcontractor, or material supplier who performs labor or supplies materials for an improvement can file a mechanic's lien against the property owner's interest even without a direct contractual relationship with the owner. This is one of the most powerful aspects of mechanic's lien law — the lien runs up the chain to the property itself, regardless of how many contractor layers separate the unpaid party from the owner.
