What Is a Construction Lien?

A construction lien, also called a mechanic’s lien, is a legal claim filed against a property by a contractor, subcontractor, or supplier who hasn’t been paid for work or materials provided.

Unpaid subcontractors use liens as leverage to secure payment.

What Does a Construction Lien Affect?

  • The property’s title
  • The ability to sell or refinance
  • The homeowner’s legal exposure, even after paying the GC
  • Resolution timelines for closing a sale

Why Are Construction Liens Important?

A subcontractor who completes electrical work but isn’t paid by a general contractor can file a lien directly against the homeowner’s property, even if the homeowner already paid the GC in full. The claim can cloud a property’s title, complicating a sale or refinance until it’s resolved.

Construction Lien vs. Lien Waiver

A construction lien is the legal claim itself, filed when payment isn’t received. A lien waiver is the document a contractor or supplier signs giving up that right, typically provided once payment is confirmed.
