Oregon Notice of Right to a Lien: 8 Business Day Deadline Guide
Oregon subcontractors, material suppliers, and equipment lessors who do not have a direct contract with the property owner must serve a Notice of Right to a Lien within 8 business days of first furnishing labor, materials, or equipment to a private construction project, under ORS 87.021. The notice must be delivered to the owner or reputed owner and the original contractor by personal delivery or first-class mail. Missing this deadline does not eliminate lien rights entirely — but it limits lien protection to labor and materials furnished in the 8 business days before the late notice was served, plus all work performed after service. Failing to serve the notice at all bars any mechanics lien claim against the property on a private works project in Oregon.
Who Is Required to Serve an Oregon Notice of Right to a Lien?
Any subcontractor, material supplier, or equipment lessor who lacks a direct contract with the property owner must serve this notice on private works projects in Oregon. If you contracted directly with the owner — and you are the original contractor — you are exempt from this requirement. Everyone else in the payment chain below the original contractor must send the notice to preserve their lien rights. That means your electrical sub, drywall crew, roofing material supplier, HVAC installer, and concrete pumping company all need to send it. There is no minimum contract value threshold listed in ORS 87.021 that exempts smaller jobs.
Oregon also requires a separate, specific notice for residential construction. On owner-occupied residential projects of four units or fewer, ORS 87.093 requires the original contractor — not just subs — to provide the owner a written notice of lien rights before beginning work. The notice under ORS 87.021 discussed in this guide applies to subcontractors on all private works, including commercial, industrial, and residential projects.
What Is the Exact 8 Business Day Deadline and How Do You Count It?
The clock starts on the first day you furnish labor, materials, or equipment to the project — not when you sign the contract, not when you mobilize to the site, but when you actually provide something of value to the job. You have 8 business days from that first-furnishing date to serve the notice. Business days under Oregon law exclude Saturdays, Sundays, and legal holidays.
Here is a practical example: if you deliver roofing materials to a Portland commercial job on a Monday, count forward 8 business days. That Monday counts as Day 1 if delivery occurred that day, but check your county's interpretation — to be safe, treat Tuesday as Day 1 and serve by the following Thursday. When in doubt, serve earlier. There is no penalty for serving the notice before you start work, and serving on your first day on the job is legally sound.
If your first furnishing date falls on a holiday, the deadline shifts to the next business day. Do not rely on calendar math alone on projects that start around federal or Oregon state holidays. Calculate each project's deadline independently.
Who Must Receive the Oregon Notice of Right to a Lien?
Under ORS 87.021(1), the notice must be delivered to two parties: the owner or reputed owner of the property, and the original contractor. If there is a construction lender on the project, Oregon does not require you to separately notice the lender under ORS 87.021 the way California requires under its preliminary notice statute — but noticing the lender is a best practice if you can identify them, because it strengthens your position if a dispute reaches a title or foreclosure proceeding.
On public works projects, the mechanics lien statutes do not apply at all — public property cannot be liened under Oregon law. Instead, you would look to Oregon's Little Miller Act (ORS 279C.380) for payment bond claims, which has its own notice deadlines and procedures.
What Information Must the Notice Include?
ORS 87.021 specifies the content of the notice. A valid Oregon Notice of Right to a Lien must include:
- The name and address of the claimant (your company)
- The name of the person who contracted with the claimant (your hiring party — the GC, a higher-tier sub, or whoever hired you)
- A description of the labor, materials, or equipment being furnished
- The name of the owner or reputed owner of the property
- A description of the property sufficient to identify it (address and legal description if available)
- The following statutory warning language, substantially as it appears in ORS 87.021(2):
"NOTICE: This is a notice that work has been performed or materials have been delivered or equipment has been rented for your project. A lien may be claimed for all work performed or materials or equipment provided after a date that is eight business days, not including Saturdays, Sundays and legal holidays, before this notice was mailed or delivered. If you have questions about this notice, you may wish to contact your contractor and the person sending this notice."
Do not rewrite the warning language. Substantial compliance is the legal standard in Oregon courts, but deviating significantly from the statutory language creates avoidable risk. Use an attorney-reviewed template.
How Must the Notice Be Delivered in Oregon?
Under ORS 87.021(3), the notice may be served by personal delivery or by first-class mail. Certified mail is not required by statute, but it is strongly recommended. Here is why: if the owner or contractor disputes receipt, you need proof. First-class mail with a certificate of mailing provides a date-stamped record. USPS Certified Mail adds delivery tracking and a return receipt that documents the recipient's signature.
According to USPS pricing effective 2026, Certified Mail costs $4.85 as the base service fee plus standard First-Class postage. Adding an electronic Return Receipt costs an additional $2.46. That is a total of roughly $7.50 to generate a documented, trackable proof-of-delivery record — a small cost on any job where you have money at risk.
If you send the notice by mail, service is deemed complete at the time of mailing — not at the time of receipt. This is critical: you do not need to wait for the owner to sign the green card before your 8-day window closes. Mail it within 8 business days and you have timely served the notice.
What Happens If You Miss the 8 Business Day Deadline?
Missing the deadline does not automatically kill your lien rights in Oregon — but it significantly reduces what you can lien. Under ORS 87.021(1), a late notice limits your lien to labor, materials, and equipment furnished in the 8 business days before the notice was mailed or delivered, plus everything furnished after service. Work performed before that window is not protected.
On a 90-day project where you forgot to send the notice until Day 30, you lose lien coverage on roughly the first 22 days of work. On a $120,000 subcontract, that could mean $30,000 or $40,000 of exposure wiped out by a missed deadline. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days — which means by the time a payment problem surfaces, your late-notice window has already cost you real money.
The only recovery path for work outside the protected window is a breach-of-contract lawsuit — no lien, no bond claim against the property, just a money judgment that may or may not be collectible if the owner or GC is insolvent.
Does Oregon Require a Notice of Right to a Lien on Every Private Project?
Yes — if you are a subcontractor, supplier, or equipment lessor without a direct owner contract, the notice is required on every private works project in Oregon, regardless of project size, project type, or your relationship with the GC. There is no "trusted GC" exception, no waiver you can sign in advance, and no course-of-dealing argument that substitutes for actual statutory compliance.
In practice, many subcontractors skip the notice on small jobs or jobs with familiar GCs, then get caught when a project goes sideways. Payment disputes do not follow a predictable pattern. A GC you've worked with for five years can still face a cash crisis, owner nonpayment, or insolvency that leaves your invoices unpaid. The notice is your insurance policy. In 2024, preliminary notices were filed on construction projects valued at over $22.7 billion nationwide, according to Lienser via DocJoist's Construction Payment Statistics — an indication that experienced contractors treat the notice as a standard business process, not an emergency response.
How Does Oregon's Notice Requirement Compare to Other States?
Oregon's 8-business-day window is one of the tightest preliminary notice deadlines in the country. California gives subcontractors 20 calendar days from first furnishing. Washington requires the Notice to Title Company within 10 days of first furnishing but operates on a different framework. Arizona's 20-day preliminary notice deadline is more forgiving. Nevada and Florida also use 20-day windows.
Oregon's compressed timeline means you cannot wait until the end of the first week to decide whether to file. By the time you've mobilized, started work, and gotten through your first few days on a job, your window is closing fast. The practical answer for most Oregon subs is to prepare and send the notice on the same day you first furnish — or before.
Frequently Asked Questions
Does a subcontractor with a direct contract with the property owner need to file this notice in Oregon?
No. ORS 87.021 applies only to claimants who do not have a direct contract with the owner. If you contracted directly with the owner and you are the original contractor on the project, you are exempt. However, your subs and suppliers — who contracted with you, not the owner — must still serve the notice to protect their lien rights.
Can I serve the Oregon Notice of Right to a Lien before I start work?
Yes, and it is a smart move. The statute sets an 8-business-day deadline from first furnishing, but there is no prohibition on serving early. Many subcontractors send the notice when they execute the subcontract, before mobilizing. Serving early eliminates deadline risk entirely and puts the owner on notice from day one.
What counts as "first furnishing" in Oregon?
First furnishing is the date you first deliver labor, materials, or equipment to the project site — or first perform work under your contract. It is not the date the contract is signed, the date you order materials, or the date you invoice. If your crew shows up on-site Monday morning and starts work, Monday is your first-furnishing date and your 8-day clock starts then.
Does this notice apply to rental equipment companies in Oregon?
Yes. Equipment lessors who rent construction equipment to a project — and who do not have a direct contract with the owner — are subject to the same ORS 87.021 notice requirement as material suppliers and subcontractors. If you rent a crane, scaffolding, or a concrete pump to a GC for use on private work, you must serve the notice within 8 business days of first delivering the equipment.
Is Oregon's Notice of Right to a Lien required on public works projects?
No. Oregon mechanics lien statutes, including ORS 87.021, apply only to private works. On public projects — state buildings, school districts, municipal projects — the property cannot be liened. Your payment protection on public work runs through the payment bond required under Oregon's Little Miller Act (ORS 279C.380), which has separate notice and claim deadlines.
What happens if I send the notice to the wrong person?
Sending notice to the wrong party — for example, to a project manager instead of the owner of record — can invalidate the notice. You must serve the owner or reputed owner and the original contractor as listed in ORS 87.021(1). Verify the owner's identity using the county assessor's records or the building permit before you mail. If you serve the wrong party, your lien rights for early work remain unprotected until a valid notice is properly served.
How long is my Oregon mechanics lien valid after I file it?
The notice under ORS 87.021 is a prerequisite — it is not the lien itself. After properly serving the notice, you still must file a claim of lien with the county clerk within 75 days of the last date you furnished labor or materials (ORS 87.035). Once filed, the lien is valid for 120 days, during which you must file a foreclosure lawsuit or the lien expires (ORS 87.055).
Can a GC waive the notice requirement on my behalf in a contract?
No. A contractual provision purporting to waive a subcontractor's statutory right to file a lien notice or lien claim is unenforceable under Oregon law. ORS 87.016 voids any clause in a contract — signed before the claimant begins furnishing labor or materials — that waives, releases, or impairs lien rights. If a GC presents you with contract language that tries to do this, it does not hold up. Send the notice anyway.
