What is an Oregon Mechanics Lien?

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.

Oregon Construction Lien Law

Key Takeaways

In Oregon, a mechanics lien is generally referred to in the statutes as a construction lien. Oregon’s Construction Lien Law (ORS Chapter 87) explains who can file, what the lien form must include, and the deadlines you must meet.

Key things to know:

  • Who can file: Many construction participants can have lien rights, including those providing labor, materials, equipment rentals, and certain design services (ORS 87.010).
  • Notice rules matter: Some claimants must send a Notice of Right to Lien, and Oregon provides required notice language and a statutory form (ORS 87.021–87.023).
  • Filing deadline: Most claimants must record the claim of lien within 75 days (ORS 87.035).

Oregon Deadlines

Oregon lien deadlines are some of the shortest in the U.S., making missed deadlines a common and costly mistake for local companies seeking payment. Your deadline depends on your role and the document you’re filing. Here are the general deadlines for Oregon lienholders.

How to File a Mechanics Lien in Oregon

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.

Step 1: Confirm your lien rights

Under Oregon law (ORS 87.010), eligible claimants include:

  • general contractors
  • subcontractors
  • material suppliers
  • equipment rental companies
  • design professionals (architects, engineers, surveyors)

You must also have served any required preliminary notice on time and must not have signed a lien waiver.

Step 2: Prepare the Oregon mechanics lien form

Your Oregon construction lien form (officially a Claim of Lien) must include:

  • claimant’s name
  • property owner’s name
  • name of the party you contracted with,
    the lien amount
  • a legal property description
  • a notarized signature

Missing any required element can invalidate your claim.

Step 3: Record the lien with the county

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.

Step 4: Serve the property owner

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.

Step 5: Enforce or collect

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.

Step 6: Release the lien

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.
