How do I file a mechanic's lien in New York?

Federal & State Law Editorial TeamLast reviewed: 2026-05-18

New York mechanic's liens on private property are governed by N.Y. Lien Law Article 2 (§§ 3-39-c).

1. Who Can File

Contractors, subcontractors, laborers, materialmen, architects, engineers, surveyors, and trucking/equipment providers who improve real property (Lien Law §§ 2, 3).

2. Preliminary / Pre-Lien Notice

New York does not require a pre-lien notice on most private projects (unlike many states). Public-improvement liens (Article 3-A) and HUD/Type 2 projects have separate notice rules.

3. Recording the Lien

File a verified Notice of Lien with the county clerk where the property is located. Deadline: within 8 months after the final furnishing of materials or performance of services for commercial property; within 4 months for single-family dwellings (Lien Law § 10). The notice must state the lienor's name, owner, type of property interest, contractor, work performed, agreed price, amount due, and property description (Lien Law § 9).

4. Service on Owner

Serve a copy of the lien on the owner within 30 days of filing for commercial projects, or 5 days for single-family residences (Lien Law § 11).

5. Suit to Foreclose

A lien is valid for 1 year from filing; extend by court order or by recording an Extension of Notice of Lien within that year (Lien Law § 17). Foreclosure suit must be commenced within the lien's validity period.

6. Priority

Liens take priority based on filing date as against subsequent purchasers and mortgagees; advances made by a lender after a notice of lien is filed are subordinate (Lien Law § 13).

7. Bond Release

Owner may discharge the lien by filing a bond for the amount of the lien plus interest (typically 110%) under Lien Law § 19(4).

8. Homestead / Residential

Single-family residential projects have shorter filing (4 months) and service (5 days) deadlines, and only one extension is permitted (Lien Law §§ 10, 17).

9. Fraudulent Lien Penalties

A willful exaggeration voids the lien and exposes claimant to damages equal to the exaggeration, plus loss of any valid portion (Lien Law § 39, § 39-a). Filing a false lien may also be larceny under Penal Law.
