Oregon subcontractors, material suppliers, and equipment rental companies that do not have a direct contract with the property owner must serve a Notice of Right to Lien within 8 days of first furnishing labor, materials, or equipment to a private construction project, under ORS 87.021. The notice must be delivered to the property owner and the original contractor (general contractor). Missing this deadline does not void lien rights entirely — but it limits protection to labor and materials furnished in the 8-day window before service. Failing to serve the notice at all is a complete bar to mechanics lien rights on private works for parties who lack a direct ownership contract. This requirement applies on both residential and commercial private projects in Oregon.
Who Must Serve an Oregon Notice of Right to Lien?
Every subcontractor, material supplier, and equipment lessor who lacks a direct contract with the property owner is required to serve a Notice of Right to Lien under ORS 87.021. If you are hired by a general contractor — not by the owner directly — you fall into this category. That includes electricians, plumbers, roofers, HVAC contractors, drywall crews, painters, concrete subs, and material yards supplying lumber, fixtures, or equipment.
The original contractor (the party with a direct ownership contract) does not need to serve a preliminary notice to preserve lien rights. But if you are even one tier removed from the owner, Oregon law requires the notice.
One practical note: if you are unsure whether you have a direct contract with the owner, serve the notice anyway. The cost of sending it is minimal compared to the cost of losing lien rights on a project.
How Many Days Do You Have to Send the Notice of Right to Lien in Oregon?
Oregon gives you 8 days from your first day of furnishing. Under ORS 87.021(1), the Notice of Right to Lien must be given not later than 8 days after you first furnish labor, materials, or equipment on the project. That countdown starts on the first day you show up on site, the first day materials are delivered, or the first day equipment is placed — whichever comes first.
Eight days is one of the shortest preliminary notice windows in the country. Many states give 20 days. Oregon gives 8. If you wait until the end of the week to handle paperwork, you may already be outside the deadline.
The consequence of late service is not a complete bar — it is a limitation. Under ORS 87.021, a notice served after the 8-day window protects only labor, materials, and equipment furnished on or after the 8th day before the notice was served. Work performed before that rolling window is unprotected.
Example: You first furnish on October 1. You serve notice on October 20. Your lien rights are limited to work from October 12 forward. Everything you furnished between October 1 and October 11 is exposed.
Who Must Receive the Oregon Notice of Right to Lien?
Under ORS 87.021, the Notice of Right to Lien must be given to both the property owner and the original contractor (general contractor). If there is a construction lender involved in the project, Oregon law also permits service on the lender to protect against disbursements already made — though the statute's core mandatory recipients are the owner and the GC.
"Given" under Oregon law means actual delivery, not just mailing. ORS 87.021(4) specifies the permissible methods of service:
- Personal delivery to the recipient or the recipient's agent
- Mailing by certified mail or registered mail with return receipt requested, to the last known address
When mailing, the notice is considered given on the date it is postmarked, not the date it is received. That distinction matters: if you mail on Day 8, you have complied even if the owner receives the envelope on Day 11.
Keep your Certificate of Mailing. If a lien dispute ever reaches court, your proof of timely service is what stands between you and losing the claim. USPS Certified Mail costs $4.85 as the base service fee in 2026, according to USPS Notice 123, plus standard First-Class postage. That is a trivial expense relative to any subcontract value.
Is the Oregon Notice of Right to Lien Required on Every Project?
The notice is required on every private construction project where you lack a direct contract with the owner — residential or commercial. Oregon law does not carve out small jobs, short-duration projects, or specific project types from the ORS 87.021 requirement.
Residential projects: The notice is required. In fact, on owner-occupied residential construction, Oregon law imposes additional disclosure requirements under ORS 87.007 that contractors must provide to the homeowner before beginning work. The ORS 87.021 preliminary notice requirement for subs and suppliers is separate and runs on top of those disclosure rules.
Commercial projects: The notice is equally required for subcontractors and suppliers without a direct ownership contract.
Public works projects: Oregon's mechanics lien statutes apply to private property only. Public works projects — jobs where the owner is a government entity — are not subject to mechanics liens. Bond claim procedures under ORS 279C apply instead on public projects. The Notice of Right to Lien under ORS 87.021 is not the vehicle for public works claims.
What Are the Form Requirements for an Oregon Notice of Right to Lien?
Oregon law prescribes the required content for a Notice of Right to Lien. Under ORS 87.021, the notice must include, at minimum:
- The name of the claimant furnishing labor, materials, or equipment
- The name of the person who hired the claimant (i.e., the GC or upper-tier sub)
- A description of the labor, materials, or equipment being furnished
- The address or legal description of the property where the work is being performed
- A statement that if the bills are not paid, the claimant has the right to enforce a lien against the property
Oregon also provides a statutory form in ORS 87.021(2) that, if substantially followed, satisfies the notice requirement. Using a compliant, attorney-reviewed template is the safest approach. Errors in required content — wrong property description, missing claimant name, omitted statement of lien rights — can undermine the notice's legal effectiveness.
What Happens If the Oregon Lien Notice Is Late or Not Sent?
If you serve the Notice of Right to Lien late, your lien rights are limited to work furnished in the 8 days immediately preceding service. Work furnished before that window is unprotected under ORS 87.021.
If you never serve the notice at all, you forfeit mechanics lien rights entirely on that project for any work you performed — with no exception for hardship, good faith, or lack of knowledge. Oregon courts have consistently treated the preliminary notice as a condition precedent to lien enforcement.
The financial stakes are real. According to Rabbet's 2024 Construction Payments Report, 82% of contractors face payment waits of over 30 days, up from 49% just two years earlier. Oregon subcontractors who skip the preliminary notice hand over their strongest collection tool before a payment dispute even begins.
Beyond lien rights, losing your lien position also affects leverage in negotiations. An owner or GC who knows you cannot file a lien has little incentive to pay quickly. The notice is not just a legal form — it is a payment pressure mechanism.
Oregon Lien Notice Requirements: Commercial vs. Residential — Is There a Difference?
The 8-day notice deadline under ORS 87.021 applies to both commercial and residential private construction projects without distinction. The statute does not create a separate timeline or form requirement based on project type.
Where residential projects differ is in the pre-construction disclosure requirements under ORS 87.007, which require contractors to provide homeowners with a specific written notice about lien rights before construction begins. That is a separate obligation from the ORS 87.021 preliminary notice that subs and suppliers must serve after first furnishing.
Practical difference for subs: On a residential remodel, you may be working on a project where the homeowner has no idea that lower-tier contractors have lien rights. Serving the Notice of Right to Lien puts that fact on record with the owner directly. On some residential jobs, that notice alone prompts an owner to make sure the GC pays their subs — because the owner now knows their home is exposed.
How Does the Oregon Notice of Right to Lien Connect to Filing a Mechanics Lien?
The Notice of Right to Lien is a prerequisite — not the lien itself. Serving it on time preserves your ability to file a mechanics lien later if you go unpaid. The mechanics lien itself, under ORS 87.035, must be filed within 75 days after the last date you furnished labor, materials, or equipment on the project (for residential projects) or 75 days for all private projects under ORS 87.035.
The timeline flows like this:
- First day of furnishing — 8-day clock starts for Notice of Right to Lien (ORS 87.021)
- Serve the Notice of Right to Lien — must be postmarked or delivered within 8 days
- Last day of furnishing — 75-day clock starts for filing the mechanics lien itself (ORS 87.035)
- File the lien claim — must be filed with the county recorder in the county where the property sits
Missing Step 2 makes Step 4 unavailable. You cannot backfill a skipped preliminary notice by filing the lien early.
According to Lienser data cited by DocJoist's Construction Payment Statistics (2024), preliminary notices were filed on construction projects valued at over $22.7 billion in the United States in 2024 — a figure that reflects how seriously the industry takes these protections. Oregon subcontractors who skip the preliminary notice are opting out of a system designed specifically to protect them.
Frequently Asked Questions
Does every Oregon subcontractor need to send a Notice of Right to Lien?
Any subcontractor, supplier, or equipment lessor that does not have a direct contract with the property owner must serve a Notice of Right to Lien under ORS 87.021. If you are hired by the GC — not the owner — you need this notice on every private project, regardless of project size or duration. The only parties exempt are those contracting directly with the owner.
What is the Oregon preliminary notice deadline for subcontractors?
Oregon requires the Notice of Right to Lien to be served within 8 days of first furnishing labor, materials, or equipment, under ORS 87.021(1). This is one of the shortest preliminary notice windows in the U.S. The 8-day clock starts on your literal first day of work or first delivery — not when the project breaks ground or when your contract is signed.
What counts as the "first day of furnishing" in Oregon?
The first day you furnish labor, materials, or equipment to the project. That means the first day your crew shows up on site, the first delivery of materials, or the first day equipment is placed. It is not the date your subcontract is signed or the date the GC tells you to start — it is the date actual work or delivery begins.
Who receives the Oregon Notice of Right to Lien?
Under ORS 87.021, the notice must be given to the property owner and the original contractor (general contractor). Service by certified or registered mail to the last known address of each recipient is a valid method. Keep your tracking receipts and Certificate of Mailing as proof of timely service.
Can you still file an Oregon mechanics lien if you missed the 8-day notice deadline?
If you served the notice late, your lien rights are limited to work furnished in the 8 days before you served the notice. If you never served the notice, you cannot file a valid mechanics lien on that project for any of your work. Oregon courts treat the preliminary notice as a condition precedent to lien enforcement — there is no cure for a complete failure to serve.
Is the Oregon Notice of Right to Lien different for residential vs. commercial projects?
The ORS 87.021 notice requirement — including the 8-day deadline, required recipients, and form content — is the same for both residential and commercial private projects. Residential projects have additional pre-construction disclosure rules under ORS 87.007 that apply to contractors, but those do not replace the ORS 87.021 preliminary notice obligation for subs and suppliers.
Does the notice apply to public works projects in Oregon?
No. Oregon's mechanics lien statutes, including the Notice of Right to Lien under ORS 87.021, apply only to private property. Public works projects — where the owner is a government entity — fall under a different legal framework (ORS 279C), and bond claims are the applicable remedy, not mechanics liens.
How long do you have to file the mechanics lien itself after serving the notice?
Serving the Notice of Right to Lien preserves your right to file a mechanics lien, but you must still file the lien itself. Under ORS 87.035, the lien must be filed with the county recorder within 75 days after the last date you furnished labor, materials, or equipment on the project. Missing that deadline extinguishes the lien right even if your preliminary notice was timely.
