Demanding Foreclosure of a Rochester Public Mechanic’s Lien

Reviewed September 7, 2026.

A mechanic’s lien on account of a public improvement reaches applicable contract funds. When addressing such a lien for a Rochester-area project, the demand-to-enforce procedure is Lien Law § 21-a. The comparable private-improvement procedure is § 59.

What a Section 21-a notice requires

The notice must require the lienor to commence an enforcement action by a specified date at least 30 days after service, or appear at a specified time and place to show cause why the lien should not be vacated. The statute requires personal service on the lienor or service in a manner directed by the court. A routine letter or certified mailing should not be assumed to satisfy that requirement.

Information counsel should confirm

• The public contract, improvement, agency and fund affected by the lien.
• The lienor’s correct identity, lien amount, filing date and all offices where filed.
• Whether an enforcement action, extension, bond or deposit already exists.
• The proposed method and actual date of service.
• A compliant enforcement deadline and the proper court, location and return date.
• The exhibits and affidavits needed for any later court application.

The former sample on this page used obsolete dates, a former firm address and a particular courthouse. This checklist replaces that sample; a notice must be prepared for the actual lien, service plan and court procedure.

What happens after the deadline?

If the lienor does not commence the required action, discharge is not automatic. The applicant must seek a Supreme Court order and provide the statutory proof of service and noncommencement. A lienor receiving the notice should promptly review it with counsel and should not assume ordinary negotiations or a standard lien extension will satisfy the demand.

Public liens also have continuation requirements under Lien Law § 18. Calendar the demand deadline separately from the lien’s ordinary expiration date.
