What Are Oregon Sellers Required to Disclose When Selling a Home?
Oregon law requires home sellers to complete the OREF 020 Seller’s Property Disclosure Statement before going under contract. The form covers 50+ questions about title, structure, systems, water, sewer, seismic risk, and environmental hazards. You answer based on your actual knowledge — and you cannot claim “unknown” for the final material defects question. Failing to disclose known issues exposes you to fraud claims, repair cost lawsuits, or deal rescission — even after closing.
Most Portland sellers think of the disclosure form as paperwork. It isn’t.
It’s a legal document. And the difference between completing it carefully and rushing through it is the difference between a clean closing and a lawsuit that arrives six months after you’ve already moved out.
Oregon’s seller disclosure requirement is codified under ORS 105.462–105.490. The form — the OREF 020 Seller’s Property Disclosure Statement — is more than 50 questions long, covering every major system and structural element of your home. And there’s one standard you can’t get around: you answer based on your actual knowledge at the time of disclosure.
That last part matters. You don’t need to hire an inspector before you fill out the form. But if you know something — and you answer “unknown” or leave it blank — that can be considered fraud.
This is exactly the kind of question I walk through with every seller before we go live. Let’s break it down.
What Does the OREF 020 Cover?
The form is organized into sections — think of it as a structured conversation about your home’s entire history:
- Title and easements — access rights, deed restrictions, boundary disputes
- Water — well, municipal connection, water pressure issues, any past flooding
- Sewer system — public sewer, septic details, prior pumping or repairs, known issues with the lateral
- Dwelling structure — roof, foundation, framing, insulation, unpermitted additions
- Dwelling systems — HVAC, electrical, plumbing, appliances
- Environmental hazards — radon, asbestos, mold, lead-based paint (required for pre-1978 homes under federal law), underground storage tanks
- Common interests — HOA dues, assessments, rules, and any pending litigation
- Seismic — earthquake-related disclosures, liquefaction zones, landslide risk
- General — a catch-all for anything that materially affects the property or its value
That final “general” section ends with a question you cannot answer “Unknown” to: Are there any other material defects that could affect the property or its value? You must say Yes or No. If Yes, you must explain.
This is where a lot of sellers get caught off guard. They rush through the rest of the form, then face this open-ended question with no guidance. If you’re unsure what qualifies as a material defect, talk to your agent before you answer.
What “Selling As-Is” Doesn’t Protect You From
I hear this from sellers regularly: “I’m listing it as-is, so I don’t need to worry about disclosures, right?”
Wrong.
An “as-is” clause in the purchase agreement does not remove your disclosure obligation. Under ORS 105.464, you are still required to complete the OREF 020 regardless of how the property is listed. An as-is clause means the buyer accepts the property in its current condition — not that you can hide what that condition is.
If you fail to disclose a known material defect, the buyer can sue you for repair costs after closing. In serious cases — particularly where there’s evidence you concealed something — you can face fraud claims. Defending yourself against that kind of lawsuit costs tens of thousands of dollars and years of stress, even if you ultimately prevail.
The safest rule: when in doubt, disclose.
What Portland Sellers Most Commonly Miss
After years of listing homes across the Portland Metro — West Hills, Forest Heights, Beaverton, Alameda, Northwest Heights — here are the areas where sellers most often overlook something or underestimate what needs to be disclosed:
Sewer laterals. Portland has a large stock of older homes, and aging clay or cast-iron sewer laterals are common. If your home has had a sewer scope done — or if you know the lateral has been repaired or is in rough shape — that belongs on the disclosure. Buyers in Portland typically order sewer scopes as part of the inspection process anyway, so surprises here tend to damage trust and derail deals.
Moisture and mold. Oregon’s climate means crawl spaces and basements take a beating. If you’ve ever had standing water, remediation work, or visible mold in a crawl space, attic, or basement, it goes on the form. “We had it fixed three years ago” is still a yes — followed by a brief explanation.
Foundation issues. Hairline cracks are common and often benign. But if you’ve had a structural engineer look at a crack, if you’ve done foundation repair, or if you’re aware of shifting signs, disclose it. This is one of the most litigated areas in real estate post-closing.
Radon. High radon levels are surprisingly common in the Willamette Valley. If you’ve had a radon test done or a mitigation system installed, that needs to be disclosed under the environmental hazards section. Buyers will often test for it during inspection regardless — and a system you failed to mention becomes a credibility problem.
Unpermitted work. That finished basement, the addition from the 1990s, the new electrical panel the previous owner put in — if you know it was done without permits, it goes on the form. Buyers and their lenders will likely discover it through a permit search anyway.
Water intrusion history. Any past storm damage, leaks, or flooding — even if fully repaired — should be noted. Oregon’s flood disclosure requirements are specific about this, and incomplete disclosure here is a common source of post-closing disputes in the Portland area.
Before you list, it’s worth reading through your full disclosure form carefully with your agent rather than filling it out alone at the kitchen table the night before signing. It takes time to do well — and it protects you.
The Buyer’s 5-Day Rescission Right
Here’s something sellers often don’t realize: once you deliver the completed OREF 020 to a buyer under contract, they have five business days to revoke their offer — with no reason required and their earnest money returned in full.
This isn’t a penalty for bad disclosures. It’s how Oregon law works. The clock starts the day after both events have occurred: the effective date of the purchase agreement AND the date the disclosure is delivered. Both must happen before the window opens.
If you fail to provide the disclosure at all, the buyer’s right to revoke continues all the way until closing.
The practical takeaway: have your disclosure completed and ready to deliver at contract. Don’t hold it back or drag your feet — that only extends the buyer’s revocation window and creates unnecessary uncertainty in your transaction.
What Oregon Doesn’t Require You to Disclose
Worth knowing: Oregon law (ORS 93.275) does not require sellers to disclose whether someone died in the home — whether by natural causes, suicide, or crime. That’s different from many other states, including California. Events like that are not considered “material facts” under Oregon law because they don’t affect the physical condition or title.
If a buyer asks directly, that’s a different conversation — work with your agent on how to respond. But you’re not required to volunteer it on the form.
How Disclosure Fits Into Your Pre-Listing Strategy
The disclosure form is one of several pre-listing requirements unique to the Portland Metro. If you’re selling inside Portland city limits, Oregon’s Home Energy Score requirement is another mandatory step before you can go live on the RMLS.
And if you’re still deciding what to fix before listing, you’ll want a clear picture of what you’re disclosing first — because sometimes what needs to be disclosed directly influences that decision. There’s no point investing in a kitchen update if a foundation issue is going to come up in inspection and reopen negotiations anyway.
Once your disclosure is complete, pricing your home correctly becomes a much more grounded conversation. Buyers factor known conditions into their offers — and so will appraisers. A seller who has done their sewer scope, knows their foundation is solid, and can hand a buyer a clean, transparent OREF 020 is in a fundamentally stronger negotiating position than one who’s hiding behind as-is language.
The disclosure isn’t just a legal obligation. Done right, it’s a strategic asset.
Your specific situation — the condition of your home, what you’ve improved, what you know about the property’s history — shapes how you approach this document. That’s where working with an experienced listing agent makes a real difference. I walk through every section of the OREF 020 with my sellers before we ever hit the market, and it saves headaches — and sometimes deals — down the line.
Frequently Asked Questions
Do I have to fill out the OREF 020 if I’m selling my Portland home as-is?
Yes. An as-is listing does not exempt you from Oregon’s disclosure requirement under ORS 105.464. You are still required to complete the OREF 020 Seller’s Property Disclosure Statement and deliver it to any buyer under contract. “As-is” means the buyer accepts the property in its current condition — not that you’re off the hook for disclosing what that condition is.
What happens if I forget to disclose something on the Oregon seller disclosure form?
If you unknowingly omit something, you’re generally protected as long as you disclosed based on your actual knowledge. But if you knew about a defect and failed to disclose it, you can be sued for repair costs — and in cases involving active concealment, you may face fraud claims. After closing, buyers have the right to pursue you for undisclosed material defects. Oregon courts take disclosure obligations seriously.
How long does a buyer have to revoke after receiving the OREF 020 disclosure?
A buyer has five business days from the later of: (1) the effective date of the purchase agreement, or (2) the date the seller delivers the completed disclosure statement. During that window, the buyer can revoke their offer for any reason and receive a full refund of their earnest money. If you never deliver the disclosure, that right to revoke continues until closing.
Does the OREF 020 require me to disclose if someone died in my home?
No. Oregon law (ORS 93.275) does not require sellers to disclose deaths in the property — whether by natural causes, suicide, or crime. Unlike California and some other states, Oregon treats these as non-material facts that don’t affect the physical condition or title. You are not required to volunteer this information on the disclosure form.
What’s the last question on the OREF 020, and why does it matter?
The final question asks whether there are any other material defects that could affect the property or its value. Unlike most of the form, you cannot answer “Unknown” — you must say Yes or No. If you answer Yes, you’re required to explain. This catch-all question is one of the most common triggers for post-closing disputes when sellers answer it vaguely or skip it entirely.
Seller disclosure in Oregon isn’t optional, and it isn’t a formality. The OREF 020 is your legal record of what you knew about your home at the time of sale. Done carefully, it protects you. Rushed through, it’s a liability waiting to materialize.
If you’re getting ready to list — or even just thinking about it — let’s talk through your disclosure picture before anything else. That conversation shapes everything from pricing to negotiation strategy.
