Until very recently, contractors performing excavation and site preparation work did not have the right to file a mechanic’s lien in Pennsylvania unless a building or other improvement was actually constructed at the site. That rule abruptly changed on May 17, 2013 in a decision by the Pennsylvania Superior Court in B.N. Excavating, Inc. v PBC Hollow-A, L.P., et. al. Based on this decision, contractors now have the right to file mechanic’s liens in Pennsylvania for excavation and site preparation work even if a building or other structure is not ultimately constructed at the site. This is a significant change in the application of the Pennsylvania Mechanic’s Lien Law.
