What Is a Mechanic’s Lien on an Albany Construction Project?

Reviewed September 7, 2026.

A mechanic’s lien is a statutory security right for qualifying construction labor or materials. On an Albany private-property project, an eligible claimant may assert a lien against the owner’s interest in the improved real estate under Lien Law § 3. Eligibility, owner consent, the unpaid amount and the available lien fund must be assessed; an unpaid invoice alone does not establish every requirement.

On a New York public improvement, § 5 provides a lien against qualifying project funds due or to become due under the public contract, rather than public real estate. A public lien does not authorize the sale of a government building. Federal projects and bond claims have separate rules.

What does filing accomplish?

A properly prepared, filed and served lien can preserve security and may help bring a payment dispute to resolution. It does not decide whether the debt is owed, guarantee available funds or automatically collect payment. An owner or contractor may dispute the lien, seek statutory relief, or substitute a discharge bond.

If settlement does not resolve the matter, lien enforcement may require a foreclosure action. A private-property judgment can lead to a judicial sale subject to applicable priorities; public and bonded liens involve different security. Collectability, defenses and litigation cost should be considered before proceeding.

Which deadlines matter?

§ 10 generally permits a private lien within eight months of last qualifying work or materials, with a four-month single-family rule and a defined developer-subdivision exception. Two-family property is not automatically subject to four months. Retainage has a separate 90-day period after release was due.

For public improvements, § 12 permits filing before completion and acceptance and within 30 days after both. Separate service, proof, duration and enforcement requirements must also be met. Obtain advice early, using the actual project documents and work dates.
