How to Calculate Oregon Mechanics Lien Deadlines
Oregon suppliers must record a lien within 75 days after their last delivery or after completion of construction, whichever comes first, and sue within 120 days of recording. The Notice of Right to a Lien protects only deliveries from 8 business days before it is given, so send it at the start of every job.
Public date calculations cover Florida and Kansas. Oregon dates require qualified review.
Risk context
Oregon is High Risk for Suppliers
Oregon's recording clock runs from the earlier of your last delivery or completion of construction, and its Notice of Right to a Lien covers only deliveries from 8 business days before the notice. A supplier who waits for an unpaid invoice before sending notice can end up with a lien for a fraction of the balance. Material-only suppliers need the notice on commercial jobs as well as residential ones.

Scroll sideways to see all deadline details.
| Deadline Type | Timing | Details |
|---|---|---|
| Lien Filing Deadline | 75 days after last furnishing or completion of construction, whichever is earlier | Record the claim of lien with the county recording officer (ORS 87.035). Completion includes substantial completion, a posted and recorded notice of completion, or abandonment (ORS 87.045). |
| Preliminary Notice | Notice of Right to a Lien, within 8 business days of first delivery to cover every delivery | Required to preserve your right to file a lien later, unless the owner ordered the materials. Deliver it to the owner in person or by registered or certified mail. It protects only materials delivered from 8 business days before it is given, so a late notice leaves earlier deliveries unprotected (ORS 87.018, 87.021). |
| Mortgagee Copy | Within 8 business days after delivery | To keep priority over a recorded mortgage, also give the mortgagee a copy of the notice within 8 business days after delivery (ORS 87.025(3)). |
| Notice of Filing | Within 20 days after recording | Mail the owner and any mortgagee a notice of filing with a copy of the claim. Missing it costs you the right to recover costs and attorney fees (ORS 87.039). |
| Enforcement Deadline | 120 days after filing | Lawsuit to foreclose on the lien must be filed by this date. If the claim states an extended payment term, the 120 days run from the end of that term, subject to the 2-year limit in ORS 87.055. Give the owner and mortgagee notice of intent to foreclose at least 10 days before suing (ORS 87.055, 87.057). |
| Statutes | Governing statutes | ORS §87.001 et seq.; §§87.010,021,035,039. Also ORS 87.018, 87.025, 87.045, 87.055, and 87.057. |
Supplier pitfalls
Common Supplier Mistakes in Oregon
Missing the Notice of Right to a Lien
The notice protects only deliveries made from 8 business days before it is given. Suppliers who wait until an invoice goes unpaid can lose lien rights on most of the job. Commercial jobs are not exempt for material-only suppliers.
Counting 75 days from the wrong date
The 75 days run from your last delivery or from completion of construction, whichever comes first. If construction is completed while you are still delivering, the clock starts at completion, not at your final delivery.
Stopping after the lien is recorded
Recording starts three more clocks: mail the notice of filing within 20 days, send the notice of intent to foreclose at least 10 days before suing, and file the foreclosure suit within 120 days of recording.

Common questions
Frequently Asked Questions
How do I calculate an Oregon lien deadline?
Start with two dates: your last delivery and the date construction was completed. Take the earlier date and count 75 calendar days to get your recording deadline. For example, if your last delivery was March 4, 2026 and construction was completed after that, record the lien by May 18, 2026. From the recording date, count 20 days for the notice of filing and 120 days for the foreclosure suit.
Does Oregon require a preliminary notice?
Yes. Suppliers must give the owner a Notice of Right to a Lien unless the owner ordered the materials. You can give it at any time, but it protects only materials delivered from 8 business days before it is given, so send it within 8 business days of your first delivery. Material-only suppliers need it on commercial jobs too. Our preliminary notice deadline guide explains how to build notice into intake.
How long do I have to enforce an Oregon lien?
120 days after recording the claim of lien, or 120 days after the end of an extended payment term stated in the claim, subject to the 2-year limit in ORS 87.055. Give the owner and mortgagee written notice of intent to foreclose at least 10 days before filing suit (ORS 87.055, 87.057).
Are these the 2024 Oregon lien law deadlines?
This guide covers current Oregon law, reviewed in September 2026 against the 2025 edition of ORS chapter 87, rather than a 2024 snapshot. The 75-day recording window, the 8-business-day notice rule, and the 120-day enforcement period come from ORS 87.021, 87.035, and 87.055. If your claim depends on the law as it stood in 2024, confirm the version in effect with an Oregon construction attorney.
