Pennsylvania Mechanic Lien Deadlines

General Contractors — 6-Month Filing Deadline

General contractors in Pennsylvania must file a Claim of Mechanic Lien within 6 months of the completion of work on the project. The mechanic lien must be filed in the office of the Prothonotary (clerk of court) in the county where the property is located. The mechanic lien claim must contain a description of the property, the nature and amount of the claim, and the name of the owner.

For commercial projects, no preliminary notice is required prior to filing. For residential projects, the general contractor must ensure that proper notice procedures have been followed before the mechanic lien can be validly enforced.

Subcontractors & Suppliers — 6-Month Filing Deadline

Subcontractors and material suppliers must also file their Claim of Mechanic Lien within 6 months of the completion of work on the project. On residential projects, the subcontractor or supplier must have served a timely Notice of Furnishing within 30 days of first furnishing as a prerequisite to a valid mechanic lien.

The mechanic lien claim must be verified by affidavit and must include all information required by the statute, including the amount claimed, the property description, and the identity of the parties.

Completion Date Determination

The 6-month mechanic lien filing period runs from the date of completion of the overall project, not from the date the individual claimant last furnished labor or materials. This is a critical distinction in Pennsylvania law. Completion is generally defined as the point at which the project is substantially complete and ready for its intended use.

Disputes over the completion date can significantly affect mechanic lien rights. Claimants should carefully document the progress of work and any events that may affect the determination of the completion date.

Mechanic Lien Claim Form & Filing Requirements

The mechanic lien claim must be filed in the office of the Prothonotary in the county where the property is located. It must contain a verified statement of the amount claimed, a description of the labor or materials furnished, the property description, and the names of the parties involved. The statutory form should be followed closely to avoid technical defects that could invalidate the mechanic lien.
