How to File a Mechanic’s Lien in Queens

Reviewed September 7, 2026.

For a private construction project in Queens, file the notice of mechanic’s lien with the Queens County Clerk, the clerk for the county where the property is located. Filing, service and later enforcement are separate steps. Clerk acceptance does not establish that the lien is valid.

1. Identify the project and property

Confirm the record owner, legal property interest, borough, block and lot, street address, claimant’s legal name and the party that hired the claimant. Review the contract, changes, payment ledger, releases and any licensing requirement. Condominium units and common-element work need special attention; a building’s street address alone may not identify the interests that can be liened.

2. Calculate the filing deadline

Lien Law § 10 generally allows eight months after the last qualifying work or materials on a private improvement, with a four-month rule for single-family dwellings and a separate 90-day rule for retainage after its release was due. The statute contains a defined developer-owned subdivision exception. Two-family property is not automatically subject to four months. Confirm the classification and trigger dates before waiting.

3. Prepare and file a verified notice

The notice must satisfy § 9, including the claimant, owner and contracting-party information; labor or materials; amount and unpaid balance; relevant dates; and adequate property description. Reconcile the amount and obtain the required verification.

Consult the Queens County Clerk’s current filing information for submission methods, forms of payment and practical requirements. The Queens Block and Lot office requires the property’s block and lot and lists a separate $5 affidavit-of-service filing fee. The statutory NYC notice-filing fee is $30 under CPLR 8021; service-proof filing and other services can add charges. Confirm the total and obtain a filed copy and receipt.

4. Serve the notice and file proof

Section 11 governs service on the owner, and § 11-b requires certified-mail service on specified contracting parties, including the general contractor for certain lower-tier claims. The private-lien service window is five days before through 30 days after filing. File the required proof within 35 days after filing the notice.

5. Preserve the claim after filing

Calendar the one-year private-lien duration and the extension or foreclosure requirements in § 17. A statutory demand may require earlier action. Filing the lien does not itself obtain payment.

Public improvements follow different rules. They generally concern project funds, not a lien on public real estate, and require filings with the proper public officials under § 12, with separate service and deadlines. Do not use the private-property process just because the project is physically in Queens.
