What Portland Home Sellers Must Disclose in Oregon: The OREF 020 Guide
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: 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
