Your complete guide to Oregon mechanics lien filing deadlines and the construction lien process steps.
An Oregon mechanics lien, officially called a construction lien (ORS Chapter 87), is a legal claim filed against a property to secure payment for unpaid labor, materials, or services. If the property owner doesn't pay, your lien gives you the right to force a sale of the property to recover what you're owed.
Oregon's construction lien law covers general contractors, subcontractors, material suppliers, equipment rental companies, and design professionals such as architects and engineers. It's one of the strongest tools available to protect your right to payment in Oregon.
This Oregon lien guide by Northwest Lien — processing mechanics liens since 1999 — covers the complete Oregon mechanics lien (construction lien) process: required forms, exact deadlines, eligibility rules, and common filing mistakes. It also covers Oregon's required notices (Notice of Right to Lien and Information Notice to Owner) and answers the most common Oregon construction lien FAQs. Our lien services team has helped Oregon contractors recover approximately $5 million in unpaid work each year.
Oregon Construction Lien Law

Filing a construction lien in Oregon involves six steps: confirming eligibility, preparing the lien form, recording with the county, serving the owner, enforcing if needed, and releasing after payment.
Under Oregon law (ORS 87.010), eligible claimants include:
You must also have served any required preliminary notice on time and must not have signed a lien waiver.
Your Oregon construction lien form (officially a Claim of Lien) must include:
Missing any required element can invalidate your claim.
File the completed form with the county recording office where the project is located, regardless of where your business is based. If the project spans multiple counties, record in each one.
After the county auditor records the lien, it’s the claimant’s responsibility to send a copy of it to the property owner. This must be done within 20 days of the recording. If you forget to send the lien to the property owner, it will not invalidate the lien, but it will mean you won’t be able to recover the legal fees you were charged during the lien process.
Most property owners settle once a lien is on record. If they don’t, you have 120 days from the recording date to enforce, meaning file a lawsuit to foreclose the lien. After 120 days, the lien expires.
After receiving payment, record an Oregon lien release with the same county office where you filed. A lien release is different from a lien waiver; make sure you’re using the right document.

In Oregon, the most common types of liens are construction liens (mechanics’ liens), judgment liens, tax liens, and HOA liens. For contractors and suppliers, the construction lien is the primary legal tool for securing payment for unpaid labor or materials provided to a specific property.
You only have to include a property description in Oregon for identification purposes. This usually includes the address, if you know what it is. This is one of the few steps in filing a mechanic’s lien in Oregon that is more relaxed than in other states.
While the legal property description isn’t required, it is smart to include it if you have this. This will ensure superior legal coverage.
For an Oregon mechanic’s lien, you can only include the contractual interest and recording fee in the lien amount. While this is true, it may be possible to recover reasonable court costs and attorney fees during the foreclosure proceedings.
Yes. It is a requirement to have the lien notarized. The claimant’s attorney can sign the lien if they know the situation; however, any party signing the lien can be subject to court proceedings as a fact witness.
Mechanic liens in Oregon are documents that are recorded in the county recorder’s office. To ensure your mechanic’s lien is valid, it’s required to record the lien where the work is physically done. Each Oregon county has specific requirements for filing a mechanic’s lien.
You must send notice that the lien was filed and a copy of the lien to the mortgagee, owner, and anyone else with a recorded security interest in the property. This must be done within 20 days of filing the lien.
You have just 120 days to file or begin the action to enforce when filing a mechanic’s lien in Oregon. It is possible to have the deadline extended by 120 time periods for up to two years. However, this is only the case if the parties have agreed on the extended payment plan and the plan’s terms are outlined in the lien paperwork.
In most situations, no. The mechanic’s lien only has priority over a lien or other encumbrance attached to the land afterward. Your lien also has priority over others if these were unrecorded at the time you first provided the labor and/or materials.
Special priority is given to laborers who filed a mechanic’s lien, but this needs to be noted in the lien documents to show what portion of the lien is for labor costs. If you provided materials and labor to the project, separate the lien to indicate what part is for labor and what is for materials. You don’t have to file two different claims but do need to note what amount is for labor only.
After the lien is paid, the release has to be filed within 10 days of the claimant receiving the written request to have it released. Learn more about canceling a lien in Oregon.
If you filed the lien with Northwest Lien, let us know when you’ve been paid and we will release the lien.
The base cost to file an Oregon construction lien is $80 to $120 for the county recording fee alone, which varies by county. DIY filers must also pay additional fees for notarization, certified mail service, and potential attorney fees if errors occur. Using Northwest Lien covers all forms, notarization, service, and guarantees compliance. Check out our transparent and affordable pricing.
Yes, you can file a construction lien on a residential project in Oregon. However, general contractors must first deliver an “Information Notice to Owner” upon signing a contract for over $2,000. Subcontractors and suppliers must send a “Notice of Right to Lien” within 8 days of first furnishing materials or labor.
A mechanic’s lien, also known as a construction lien, is a legal claim entitling eligible parties to force the sale of a property if payment is not received for work done on the property. When you file a lien in Oregon and payment is still not fulfilled, you have the right to require the County Sheriff to sell the property you put work into. From there, you can collect the amount you’re owed from the sale proceeds.
Filing a lien is the single most effective method to secure payment for the labor and/or materials you put on a person’s property. Even if you have a contract with the property owner, filing a lien is almost always less expensive and time-consuming than suing for breach of contract.
In fact, in many cases, filing a lien is enough legal action to persuade property owners to settle their debts to the lienholder. Put simply, property owners do not want liens on their property. Because the lienholder has the right to seize the property, most lending institutions or other prospective buyers won’t touch a property that has a lien filed against it. With fewer interested purchasers often comes less potential profit for the property owner if they’re looking to sell, leaving them with a clouded property title and limited options.
Lien law is a tricky landscape to navigate. The team at Northwest Lien can help you take the guesswork out of filing a lien or notice, allowing you to feel confident in your filing process without having to pay for a lawyer. Experts in Oregon lien law, we find the legal description, legal owner, mail out to all parties involved, and keep accurate records. Northwest Lien also keeps you informed of all important deadlines.
Not just anyone can walk into the recording office and file a lien. Clouding someone’s title and potentially forcing foreclosure is serious business, so many state laws impose some requirements that you need to be aware of before you start work on the property.
In Oregon, the parties entitled to mechanic’s lien protection are clearly defined by statute. These parties include: 1) any person performing labor upon, transporting or furnishing any material to be used in, or renting equipment used in the construction of any improvement; 2) any person who engages in or rents equipment for the preparation of a lot or parcel of land, or improves or rents equipment for the improvement of a street or road adjoining a lot or parcel of land at the request of the owner of the lot or parcel; 3) trustees of an employee benefit plan; 4) an architect, landscape architect, land surveyor or registered engineer who, at the request of the owner or an agent of the owner, prepares plans, drawings or specifications that are intended for use in or to facilitate the construction of an improvement or who supervises the construction. Note also that there are written contract requirements in some cases and if the project requires a written contract, the lien claimant must have a valid Oregon contractor’s license.

In Oregon, a mechanics lien must be filed within the earliest of either 75 days after the claimant’s last furnishing of labor and/or materials, or 75 days after completion of construction. If the lien is filed prior to the completion of the project or before the last furnishing of labor and/or materials (whichever is appropriate) the lien is premature and invalid.

An action to enforce an Oregon mechanic’s lien must be initiated within 120 days after the filing of lien. However, this time may be extended in periods of 120 days for up to 2 years; but only if an extended payment plan has been arranged between the parties and the terms of the plan are stated in the lien itself.

An Oregon construction lien lasts for exactly 120 days from the date it is recorded. To extend this deadline or secure payment, you must enforce the lien by filing a foreclosure lawsuit in court before the 120-day period expires. If no action is taken, the lien becomes invalid.
You can access valid Oregon construction lien forms through online lien filing services like Northwest Lien. Because Oregon statutes require specific information and formatting (such as a legal property description and notarization), it is highly recommended to use a professional service rather than generic, free templates to ensure your claim is legally binding.
Property owners can fight a construction lien in Oregon by demanding a lien release if the debt was paid, issuing a formal “Notice of Demand to Commence Suit” (forcing the claimant to sue within 30 days or lose the lien), or filing a bond to discharge the lien from the property title during a dispute.
Yes, in most cases a lien is not valid unless notice has been sent to the relevant parties ahead of time.
It’s imperative to get preliminary notice out quickly. Oregon has the shortest preliminary notice deadline in the country. On residential projects exceeding $2,000, general contractors must deliver an Information Notice to Owner at the time of signing the contract with the owner, or within 5 days of the date of when the contractor knows that the contract will exceed $2,000. For any other parties (subcontractors and suppliers) on a residential project, the Notice of Right to Lien must be sent within 8 days of first furnishing to the project. On commercial projects, only material suppliers are required to send a preliminary notice (within 8 days of first furnishing), but is advisable for all parties to send it to fully protect their lien rights.
In short, it is best practice for all parties involved in a project to submit a preliminary notice in Oregon.
Oregon has two different types of notices. Contractors employed directly by the property owner are required to send an Information Notice to Owner. All lien claimants without a direct contract with the owner are required to send a Notice of Right to Lien.
Important to remember:
Any and all necessary details. The Oregon preliminary notice forms require specific language and information. Save yourself some time by submitting your notice here with Northwest Lien and we take care of the rest.
The Oregon Notice of Right to Lien is required to be submitted within 8 days of first furnishing labor and/or materials on a project. The Information Notice to Owner must be delivered at the same time as the contract with the owner is signed. If you send a Notice of Right to Lien late, it applies to the preceding 8 days from the date on which the notice is given. Failure to give the Information Notice to Owner when required is fatal to an Oregon lien claim.
Important to remember:
Both the Notice of Right to Lien and the Information Notice to Owner may be served by either personal delivery, or by registered or certified mail, return receipt requested. The Information Notice to Owner may also be sent by first-class mail as long as a certificate of mailing is provided.
