Understanding Preliminary Notices in Oregon

Oregon uses a preliminary notice system. Here's what that means in plain English: when you start working on a construction project (or deliver your first batch of materials), you need to send a document called the “Notice of Right to a Lien” to certain people within 8 days.

Imagine you're an electrician hired to wire a new office building in Oregon. Your first day on the job site is March 1st. Under Oregon law, you need to send the Notice of Right to a Lien by 8 days later. This notice goes to the property owner. Send it on time to keep your lien rights active. This is the single most important compliance step on any Oregon project.

Who Needs to Send a Preliminary Notice in Oregon?

This applies to nearly everyone who works on a construction project and wants to protect their payment rights. That includes general contractors, subcontractors (electricians, plumbers, roofers, etc.), material suppliers (lumber, concrete, fixtures), equipment rental companies, laborers, architects and engineers, and surveyors. The specific rules — like who you need to notify and your deadline — depend on your role. Check the table below to see exactly what applies to you.

Why Preliminary Notices Matter

The Notice of Right to a Lien is what keeps your lien rights active in Oregon. It's standard paperwork — sending it on time protects your payment on every project.

What If You Miss the Deadline?

Late Notice is Better Than No Notice

If you miss the 8-day deadline, don't give up. Oregon allows late notices with partial protection. A late Notice of Right to a Lien covers your work from the 8 days BEFORE you sent the notice, plus everything after. You only lose protection for the earliest work. Send it as soon as you realize you missed the deadline.

Who Must Receive the Notice of Right to a Lien?

Who you need to notify depends on your role on the project. Here's a simple breakdown:

How to Deliver the Notice in Oregon

Use one of the approved delivery methods below to make sure your notice is valid. Oregon accepts these methods:

Certified Mail — You send via USPS and get a green receipt card proving the notice was delivered. This is the gold standard because it creates clear proof of delivery.

Personal Delivery — You (or someone you designate) hand-deliver the notice directly to the recipient. Make sure to get a signed acknowledgment as proof.

Statutory Notice Language

Oregon law requires your Notice of Right to a Lien to include specific warning language. This isn't language you write yourself — it's exact wording specified by OR Rev. Stat. §§ 87.001 et seq.. Using the wrong language (or leaving it out) can invalidate your notice. LienGrid automatically includes the correct statutory language for Oregon.

Oregon Preliminary Notice FAQ

Common questions about preliminary notices in Oregon, answered so anyone can understand.

A preliminary notice is a simple document you send near the beginning of a construction project to let the property owner (and sometimes the general contractor and lender) know that you're working on their property. It's NOT a threat, a lien, or a sign that something is wrong — it's a standard business practice required by law in many states. Think of it as "checking in" to say: "I'm providing labor/materials on this project, and I expect to be paid." In Oregon, this document is officially called the "Notice of Right to a Lien" and is governed by OR Rev. Stat. §§ 87.001 et seq..
Yes, Oregon requires it. If you skip this step, you could lose your right to file a mechanics lien later — which means you'd have much less legal leverage if you don't get paid. In Oregon, the "Notice of Right to a Lien" must be sent within 8 days of when you first start working or delivering materials. The notice requirement exists to ensure transparency on construction projects — everyone involved should know who is providing labor and materials.
You have 8 days from the date you FIRST provide labor or materials to the project. Your "clock starts" on your very first day of work or your first delivery. For example, if you delivered lumber on March 1st, you'd need to send the Notice of Right to a Lien by 8 days later. Pro tip: send the notice as soon as you start a project — don't wait until the deadline is close.
In Oregon, it's officially called the "Notice of Right to a Lien" (formal document title: "NOTICE OF RIGHT TO A LIEN"). Different states use different names for essentially the same concept — you might hear it called a "preliminary notice," "notice to owner," "notice of furnishing," or "pre-lien notice" depending on the state. The Oregon version follows the requirements laid out in OR Rev. Stat. §§ 87.001 et seq..
Don't panic — a late notice is better than no notice at all. In Oregon, if you send the Notice of Right to a Lien after the 8-day deadline, it still gives you partial protection. Specifically, you'll be covered for work and materials from the 8 days BEFORE you sent the late notice, plus everything after that date. You only lose protection for the earliest work. Example: If you started work on January 1st but didn't send notice until February 15th, you'd be protected for work from 8 days before February 15th onward, but not for work done before that. Send the notice today if you haven't already.
It depends on your role on the project. Here's a simple breakdown: General Contractors (hired directly by the owner) must notify: the property owner. Subcontractors (hired by the GC or another sub) must notify: the property owner. Material Suppliers must notify: the property owner. Laborers follow the same rules as subcontractors and must notify: the property owner. Equipment rental companies follow material supplier rules and must notify: the property owner. Design professionals (architects, engineers, surveyors) must notify: the property owner. It's critical to send the notice to ALL required parties — missing even one can weaken your legal standing.
Oregon accepts these delivery methods: Certified Mail, Personal Delivery. Most people use certified mail because it gives you a receipt proving the notice was sent AND received — this is your proof if there's ever a dispute. Keep the receipt and tracking number in your project file. Important: if you use a delivery method that isn't on the approved list, your notice could be considered legally invalid even if the recipient actually received it. Don't take shortcuts with delivery.
Yes — Oregon requires the Notice of Right to a Lien to include specific warning language spelled out in OR Rev. Stat. §§ 87.001 et seq.. This isn't language you make up yourself. The state has exact wording that must appear on the notice, explaining to the property owner their rights and the potential consequences of unpaid work. Using the wrong language (or leaving it out) could make your notice invalid. This is one reason many contractors use tools like LienGrid — it automatically includes the correct statutory language for Oregon so you don't have to worry about getting it wrong.
This is a big deal: if you skip the required Notice of Right to a Lien in Oregon, you could completely lose your right to file a mechanics lien. That means if you're not paid for $50,000 worth of work, you might have no lien to fall back on. You could still pursue other legal options like breach of contract lawsuits, but those are more expensive and time-consuming than filing a lien. The preliminary notice is your insurance policy — a small upfront step that protects potentially large payments down the road. Never skip it.
Oregon's Notice of Right to a Lien requirements apply to both types of projects, but there can be important differences. Residential projects (homes, condos, small apartments) often have extra protections for homeowners — for example, some states require additional disclosures or have shorter deadlines for residential work. Commercial projects (offices, retail spaces, industrial buildings) may have different thresholds or requirements. Always check OR Rev. Stat. §§ 87.001 et seq. for the specific rules that apply to your project type, or use a compliance tool like LienGrid that automatically adjusts for the project type.
