How to File a Mechanic’s Lien in Albany

Reviewed September 7, 2026.

Before filing a mechanic’s lien on an Albany construction project, identify the property, project type, contracting parties, unpaid lienable work and all applicable deadlines. New York’s private- and public-improvement procedures differ. A form accepted by a clerk is not a legal determination that the claim is valid.

Private improvements: identify the filing period

Lien Law § 10 generally allows filing during the work or within eight months after the last qualifying work or materials. Work related to a single-family dwelling generally has a four-month period. A two-family property is not automatically subject to the four-month rule merely because it is residential. A retainage lien may be filed within 90 days after retainage was due to be released.

The single-family definition has a specific exception for developer-owned units in a subdivision filed with the municipality, where the developer improves at least two parcels under a common plan and owns the property for a purpose other than a personal residence when the lien is filed. Ownership by a company alone does not establish that exception. Condominium units, common elements and cooperative property require analysis of the actual interest, work and project; do not apply one blanket deadline to every arrangement.

Prepare and file the notice

1. Verify title and location. Identify the owner and interest to be charged and obtain a sufficient property description. For property in Albany County, consult the Albany County Clerk and an appropriate title search. Confirm the county, property identifiers and current submission requirements.
2. Reconcile the claim. Match the contract, changes, invoices, payments, credits and retainage to the lienable work or materials. Do not include an unsupported amount simply to increase negotiating pressure.
3. Complete the statutory notice. § 9 requires lienor and contracting-party information, the owner and interest, the work or materials, value, unpaid amount, first and last dates, property description and single-family status. Include attorney details if applicable and the required verification.
4. File where the property is situated. Property spanning counties can require filing in each. Confirm fees and accepted payment methods directly with the clerk. Filing and service are separate obligations.

Serve the required parties and file proof

Under § 11, serve the owner by a permitted method within five days before or 30 days after filing, and file proof with the county clerk within 35 days after filing. The method depends on the owner and circumstances.

§ 11-b separately requires certified-mail service on the specified contracting party and, for certain lower-tier claimants, the general contractor. Its service window is also five days before through 30 days after filing, with proof due within 35 days after filing. Identify the actual required recipients rather than relying on a generic instruction to serve everyone above you.

Preserve the lien after filing

A private lien generally lasts one year under § 17. Timely foreclosure and notice-of-pendency requirements, or a qualifying extension, must be addressed before expiration. A single-family lien requires a court order for extension. A discharge bond substitutes security and does not itself eliminate the lien claim. Start review early enough to resolve title, service and court issues.

Public improvements follow different rules

A New York public-improvement lien reaches qualifying project funds, not publicly owned real estate. § 12 permits filing before completion and acceptance and within 30 days after both completion and acceptance. File with the responsible department or bureau head and the designated official holding and disbursing the funds.

§ 11-c requires certified-mail service on specified contracting parties within five days before or simultaneously with filing, and proof must accompany the filed lien. Do not use the private lien’s post-filing service window. Federal projects and payment-bond claims require separate analysis.
