Oregon construction lien law gives subcontractors, material suppliers, equipment lessors, and certain laborers the right to file a lien against private property when they go unpaid — but only if they follow a strict sequence of steps governed by ORS Chapter 87. Most subcontractors who have no direct contract with the property owner must serve a Notice of Right to a Lien on the owner (and the mortgagee or construction lender, if any) no later than 8 days after first furnishing labor, materials, or equipment, under ORS 87.021. Missing that 8-day window does not eliminate lien rights entirely, but it limits protection to work furnished after a valid notice is served. Miss the lien recording deadline — 75 days after substantial completion or the last date of furnishing, depending on the claimant's tier — and lien rights are gone permanently.
Who Qualifies for Construction Lien Rights in Oregon?
Oregon lien rights extend to contractors, subcontractors, sub-subcontractors, material suppliers, equipment lessors, and certain design professionals who furnish labor, materials, or equipment used in the improvement of private real property, under ORS 87.010.
Oregon draws a key distinction based on contract tier. If you have a direct contract with the property owner, you are a "original contractor" under Oregon law and your notice obligations differ from those further down the chain. Everyone who furnishes to the project without a direct owner contract — meaning virtually every subcontractor, sub-sub, and supplier — must serve a Notice of Right to a Lien to preserve full lien protection. Laborers who provide only personal labor services have separate rights under ORS 87.010(4) and should verify their specific obligations against that statute. Oregon lien rights apply only to private projects; public works projects use bond claim procedures, not mechanics liens.
What Are the Oregon Notice Requirements Before Filing a Construction Lien?
Subcontractors and suppliers who lack a direct contract with the property owner must serve a Notice of Right to a Lien on the owner, the original contractor, and the construction lender (if any) before lien rights are fully protected, under ORS 87.021.
The 8-day rule is the sharpest edge in Oregon lien law. You must serve the notice within 8 days of first furnishing labor, materials, or equipment to the project. If you miss the 8-day window and serve the notice late, your lien rights are preserved only for work furnished after the date of actual service — everything furnished before that late notice is unprotected. If you never serve a notice at all, you lose lien rights for all work performed, with limited exceptions for original contractors. Oregon's notice requirement is not a suggestion; it is a jurisdictional prerequisite for non-original contractors.
The notice must be served by:
- Personal delivery
- First-class mail with certificate of mailing
- Certified mail, return receipt requested
Certified mail is the industry standard because it creates a documented delivery chain. USPS Certified Mail costs $4.85 as the base service fee (plus standard postage) per USPS Notice 123 — Price List effective 2026, and adding electronic Return Receipt costs an additional $2.46. That documentation becomes critical if a lien is ever challenged.
What Must an Oregon Notice of Right to a Lien Contain?
The Notice of Right to a Lien must include specific statutory content set out in ORS 87.023, including a prescribed warning statement to the owner, the claimant's name and address, the name of the person who hired the claimant, and a description of the labor, materials, or equipment being furnished.
Oregon statute ORS 87.023 specifies the exact form and language the notice must follow, including a verbatim warning to the property owner explaining that the claimant may file a lien and that the owner could potentially pay twice if the general contractor fails to pay the sub. Using a non-compliant form — even one that conveys the right information informally — risks invalidating the notice entirely. The notice must also identify the property by address or legal description with enough specificity to locate the improvement site.
What Is the Oregon Lien Recording Deadline After Work Is Complete?
The deadline to record (file) an Oregon construction lien with the county clerk depends on your role: original contractors generally have 75 days from substantial completion of the entire project or the last date they furnished labor or materials, under ORS 87.035.
Sub-subcontractors and suppliers should verify their specific recording deadline directly against ORS 87.035, as the statute addresses different claimant tiers and the trigger events can vary based on the claimant's position in the contract chain. The lien must be recorded in the county where the property is located. Oregon uses the term "claim of lien" — it is filed with the county recording office, not a state agency. Missing this deadline is an absolute bar; no court can revive an untimely lien.
Because 82% of contractors face payment waits of over 30 days, according to Rabbet's 2024 Construction Payments Report, the temptation to wait and see if payment arrives before filing a lien is understandable — but it is also the most common way contractors lose lien rights. Do not wait for a payment promise. Track your deadlines from day one.
What Must an Oregon Construction Lien Claim Contain?
A valid Oregon claim of lien must be in writing and include the claimant's name and address, the name of the person who hired the claimant, the name of the property owner (as reasonably known), a description of the labor or materials furnished, the amount claimed, and a description of the property sufficient to identify it, under ORS 87.035.
The lien must also be verified — meaning it must be signed under oath or with a verification statement. Oregon does not accept unverified lien claims. The property description does not need to be a formal legal description in every case, but it must be specific enough for the county recorder to associate it with a particular parcel. Errors in the claimant's name, the amount, or the property description can give a property owner grounds to challenge the lien's validity, so accuracy matters as much as timeliness.
What Are the Service Requirements After Recording an Oregon Construction Lien?
After recording a claim of lien, Oregon law under ORS 87.035 requires the claimant to serve a copy of the lien on the property owner within a specified period after recording.
The copy of the recorded lien must be served on the owner by personal delivery or mail. Failing to complete post-recording service does not void the lien automatically in all circumstances, but it creates a procedural defect that a property owner's attorney will use to attack the lien's enforceability. Treat post-recording service as a required step, not optional follow-through. Confirm service method and timing against ORS 87.035 and consult Oregon-licensed legal counsel for your specific situation, because the consequences of defective service can be significant.
What Is the Oregon Construction Lien Enforcement Deadline?
An Oregon construction lien must be enforced by filing a lawsuit to foreclose the lien within 120 days of recording the claim of lien, under ORS 87.055.
If you do not file a foreclosure action within 120 days of recording, the lien expires and is unenforceable — regardless of how perfectly you executed every prior step. The 120-day clock does not stop because you are in negotiations or because the owner promised to pay. If litigation is approaching and settlement looks unlikely, file the foreclosure action to preserve your rights, even if you ultimately settle after filing. Oregon courts have consistently enforced the 120-day deadline strictly.
The 120-day enforcement window is why lien rights are worth protecting from the very first day on a job. According to Rabbet's 2024 Construction Payments Report, slow payments cost the U.S. construction industry an estimated $280 billion in 2024, adding roughly 14% to total construction spending. A lien claim that is properly recorded and timely enforced is one of the few tools a subcontractor has to move to the front of the payment line.
What Are Oregon's Construction Lien Rules for Material Suppliers?
Material suppliers in Oregon have the same lien rights as subcontractors under ORS 87.010, but they must serve a Notice of Right to a Lien within 8 days of first delivering materials to the project site — the same 8-day rule that applies to all non-original contractors.
For suppliers, "first furnishing" is typically the first material delivery. If you supply materials on an ongoing basis across multiple deliveries, the 8-day clock runs from the very first delivery — not each subsequent one. A supplier who waits until the third or fourth delivery to send a notice may find that the first several deliveries are unprotected. Suppliers whose materials are not actually incorporated into the improvement may face additional challenges to lien eligibility, so document what you delivered, when it was delivered, and where it was incorporated.
Oregon does not limit lien rights based on the dollar value of materials supplied. A supplier who delivers $800 in materials has the same statutory right to a lien as one who delivers $800,000 — but both must follow the same notice and recording process.
Frequently Asked Questions
Does Oregon require a preliminary notice on public projects?
No. Oregon mechanics lien rights apply only to private property improvements. On public works projects — including state, county, city, and school district contracts — the remedy for unpaid subcontractors and suppliers is a bond claim under ORS 279C.600 et seq., not a lien on the property. The notice and deadline rules for bond claims differ from private lien law.
What happens if I serve the Notice of Right to a Lien late in Oregon?
Serving the notice late limits your lien protection to labor, materials, or equipment furnished after the date of actual service. Any work performed before the notice was served is not protected. This is not a minor technicality — on many jobs, the majority of work is done before a payment dispute arises, which means a late notice may protect very little of what you are actually owed.
Can a homeowner waive or release the requirement for a Notice of Right to a Lien in Oregon?
No. Oregon's lien notice requirement is a statutory prerequisite. A homeowner cannot agree in advance to waive the claimant's obligation to serve a notice, and a general contractor cannot provide this waiver on the owner's behalf. The notice must be properly served to protect your lien rights.
Does Oregon have a lien waiver statute?
Oregon does regulate lien waivers. Under ORS 87.007, lien waiver provisions in construction contracts that require a subcontractor to waive lien rights before payment is received are void and unenforceable. Waivers executed contemporaneously with or after payment can be enforceable. Review any contractual lien waiver language carefully with an Oregon-licensed attorney before signing.
Who receives the Notice of Right to a Lien in Oregon?
Under ORS 87.021, the notice must be served on the property owner, the original contractor, and the construction lender (or mortgagee) if one exists. Serving only the general contractor and not the owner is not sufficient. Obtain the owner's name and mailing address from the building permit, county records, or the contract itself before furnishing labor or materials.
Is there a required form for the Oregon Notice of Right to a Lien?
Yes. ORS 87.023 sets out the required form and specific warning language that must appear in the notice. Oregon does not accept a general letter as a substitute. The statute prescribes the exact wording of the owner warning, and deviating from that language creates grounds for the notice to be challenged as defective.
Can I file an Oregon lien if I was not paid the full contract amount but received some payment?
Yes. You can file a lien for the unpaid balance of what you are legitimately owed, even if partial payments were received. The lien amount must reflect only amounts actually owed and unpaid — overstating a lien claim can expose you to liability. Document all payments received and calculate the claimed amount carefully.
Does filing a Notice of Right to a Lien mean I am filing a lien?
No. The Notice of Right to a Lien is a preliminary notice that preserves your ability to file a lien later if you go unpaid. It is not the lien itself. Serving the notice does not cloud the title or create a lien on the property — it simply puts the owner on notice that you have lien rights. The actual lien (claim of lien) is a separate document recorded with the county clerk after work is complete and payment has not been received.
