Oregon construction mechanic lien rights are governed by ORS §87.001 et seq. This statute provides mechanic's lien rights to contractors, subcontractors, and material suppliers who furnish labor or materials for the improvement of real property in the State of Oregon. Oregon's mechanic lien law framework includes distinctive notice requirements that differ significantly from most other states. Oregon's notice system is unique. General contractors are not required to serve a traditional preliminary notice, but must provide a Notice of Right to Mechanic Lien to the property owner at the time of contracting. Subcontractors and material suppliers must serve a Notice of Right to a Mechanic Lien within 8 business days of first delivering materials or providing services. This notice must be sent to the property owner and to the mortgage holder of record. All claimants must file their construction mechanic lien within 75 days of the date of completion of the original contract or cessation of work. ## Source - https://mechanicslien.com/oregon Last verified: 2026-08-14.
