Oregon Mechanic Lien Enforcement Deadlines

Private Works — 120-Day Suit Deadline

Under Oregon law, a mechanic lien claimant must commence suit to enforce the construction mechanic lien within 120 days of the date the mechanic lien was filed. This enforcement period is measured from the filing date of the mechanic lien, not from the date of completion or last furnishing.

The 120-day enforcement deadline is relatively short. Claimants should begin preparing their enforcement strategy and engaging legal counsel before or immediately upon filing the mechanic lien to ensure suit can be commenced within the deadline.

Public Works — Bond Claim Suit (Between 120 Days and 2 Years)

Under ORS §279C.600 et seq., suit on a public works payment bond may not be commenced earlier than 120 days after the Notice of Claim is filed, and must be filed no later than 2 years after the date of final completion of the public improvement.

The 120-day waiting period allows the general contractor and surety time to investigate and potentially resolve the claim. The 2-year outer deadline provides a longer window for suit but claimants should not delay unnecessarily.

Prerequisites for Enforcement

Before commencing a mechanic lien enforcement suit, claimants must verify that all prerequisite steps have been completed: (1) timely Notice of Right to Mechanic Lien or Notice of Right to a Mechanic Lien, (2) timely filing of the construction mechanic lien within 75 days of completion, and (3) proper content in the mechanic lien filing.

Any deficiency in a prerequisite step may result in the mechanic lien being declared invalid, even if the enforcement suit is timely filed within the 120-day window.
