Understanding the Prelien Process on Construction Projects in Oregon by Role

Parties not in direct contract with the property owner must serve a Notice of Right to Lien within 8 days of first furnishing labor, materials, or equipment to the project. Failure to serve this notice forfeits lien rights.

Prime/ Original / General Contractors (GCs): Prime contractors in direct contract often are not required to serve preliminary notice for their own claims.

Subcontractors/Trade Partners (Subs): Subs should serve Notice of Right to Lien within 8 days after first furnishing.

Second-tier Subcontractors: Second-tier claimants should preserve delivery and service records from project start.

Lower-tier Subcontractors: Lower-tier parties should verify ownership details before serving statutory notice.

Material Suppliers: Suppliers should send notice promptly because late notice narrows lien rights.

Equipment Lessors: Lessors should track first furnishing dates carefully to meet the 8-day window.

Second-tier Material Suppliers: Second-tier suppliers should treat notice service as an immediate project-start task.
