What Is a Mechanics Lien in Pennsylvania — Complete 2026 Guide
Pennsylvania mechanics lien law under the Pennsylvania Mechanics' Lien Law of 1963 gives contractors and subcontractors 6 months from completion to file. Subcontractors must serve a Notice to Owner within 30 days of first furnishing on residential projects.
Pennsylvania 6-Month Filing Deadline
Pennsylvania gives all mechanics lien claimants — contractors, subcontractors, and material suppliers — 6 months from the last date of completion of the work to file a mechanics lien. Pennsylvania's 6-month window is one of the longer filing deadlines in the country, but the complexity of the court petition process means claimants should not wait until the last minute.
Pennsylvania Notice of Intention
Pennsylvania subcontractors and sub-subcontractors must serve a Notice of Intention to File a Mechanics Lien Claim on the property owner at least 30 days before actually filing the lien. This notice gives the owner an opportunity to pay or dispute the claim before the lien is filed. The Notice of Intention must be served by personal service or certified mail. Without this notice, a Pennsylvania subcontractor's lien is invalid.
Where to File in Pennsylvania
Pennsylvania mechanics liens are filed with the Court of Common Pleas in the county where the project property is located. Pennsylvania is one of the few states that requires filing with a court rather than a county recorder or clerk. Major filing courts include the Philadelphia Court of Common Pleas, Allegheny County (Pittsburgh), and Montgomery County.
Pennsylvania Lien Enforcement — 2 Years
After filing a Pennsylvania mechanics lien, the claimant must commence an action to obtain judgment on the lien within 2 years of filing. Pennsylvania's 2-year enforcement period is generous compared to states like California that require enforcement within 90 days. The Mechanics Lien Management State System tracks all Pennsylvania deadlines.
