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 includes more than 50 questions covering title issues, structural components, major systems, water and sewer, environmental hazards, seismic risks, and other material facts about the property.
Sellers must answer based on their actual knowledge, and failing to disclose known defects can result in lawsuits, repair claims, or even contract rescission after closing.

Why the OREF 020 Matters
Many Portland sellers view the disclosure form as routine paperwork.
It’s not.
The OREF 020 is a legal document that creates a written record of what you knew about your property at the time of sale. Completing it carefully can help prevent disputes after closing. Rushing through it can create significant liability.
Under Oregon law, disclosures are based on your actual knowledge—not assumptions or guesses. While you are not required to hire an inspector before completing the form, knowingly omitting information can expose you to legal claims.
What Does the OREF 020 Cover?
The disclosure statement is organized into several key sections:
Title and Easements
- Access rights
- Boundary disputes
- Deed restrictions
- Easements

- Municipal or well service
- Water pressure concerns
- Flooding history
Sewer Systems
- Public sewer or septic systems
- Previous repairs
- Known sewer lateral issues
Structure
- Roof condition
- Foundation concerns
- Insulation
- Unpermitted additions
Home Systems
- HVAC
- Electrical
- Plumbing
- Appliances
Environmental Hazards
- Radon
- Mold
- Asbestos
- Lead-based paint
- Underground storage tanks
HOA and Common Interests
- Dues and assessments
- Community rules
- Pending litigation
Seismic Risks
- Earthquake-related concerns
- Landslide areas
- Liquefaction zones
General Material Defects
This final section asks whether there are any other material defects affecting the property or its value.
Unlike many other questions, you cannot answer “Unknown.” You must answer Yes or No and provide details when applicable.
What “As-Is” Doesn’t Protect You From
A common misconception among sellers is that listing a home “as-is” eliminates disclosure requirements.
It doesn’t.
An as-is sale simply means the buyer accepts the property in its current condition. It does not relieve the seller of the obligation to disclose known defects.
Even with an as-is sale, failure to disclose material issues can lead to lawsuits after closing. When in doubt, disclose.
Common Disclosure Mistakes Portland Sellers Make
Sewer Lateral Problems
Older Portland homes frequently have aging clay or cast-iron sewer lines.
If you’ve had sewer repairs, a sewer scope inspection, or known issues, they should be disclosed. Buyers often perform sewer inspections during due diligence, making surprises difficult to hide.
Moisture and Mold Issues
Water intrusion, crawl space moisture, basement flooding, or mold remediation should all be disclosed—even if repairs were completed years ago.
Foundation Concerns
While minor settling cracks may be normal, prior foundation repairs, engineering reports, or known structural concerns should be disclosed. Foundation issues are among the most common sources of post-closing disputes.
Radon Testing and Mitigation
If you’ve conducted radon testing or installed a mitigation system, buyers should be informed. Radon is common in parts of the Portland Metro area.
Unpermitted Work
Known unpermitted additions, remodels, electrical work, or structural changes belong on the disclosure form. Buyers, lenders, and inspectors frequently uncover these issues during the transaction.
Water Intrusion History
Past leaks, flooding events, storm damage, or water-related repairs should be disclosed, even if fully repaired.
The Buyer’s Five-Day Right to Revoke
Many sellers don’t realize that Oregon buyers have a statutory right to revoke their offer after receiving the completed disclosure statement.
Once the OREF 020 is delivered, buyers have five business days to cancel the transaction and receive a full refund of their earnest money.
If the disclosure is never delivered, that right continues all the way until closing. For that reason, it’s best to complete and provide the disclosure as early as possible in the transaction.
What Oregon Sellers Are Not Required to Disclose
Under Oregon law, sellers are generally not required to disclose whether someone died in the home due to:
- Natural causes
- Suicide
- Crime
Unlike some states, Oregon does not consider these events material facts affecting the property’s condition or title.
How Disclosure Fits Into Your Selling Strategy
Disclosure isn’t just about legal compliance—it’s also a strategic tool.
A complete and transparent disclosure package can:
- Build buyer confidence
- Reduce surprises during inspections
- Strengthen negotiations
- Support accurate pricing decisions
- Minimize post-closing disputes
Sellers who understand their home’s condition and disclose it honestly are often in a stronger position than sellers who rely on vague answers or as-is language.
Frequently Asked Questions
Do I have to complete the OREF 020 if I’m selling my home as-is?
Yes. Oregon law still requires sellers to complete the disclosure form, even when the property is sold as-is.
What happens if I forget to disclose something?
If the omission was truly unknown, you’re generally protected. However, knowingly failing to disclose a material defect can result in repair claims, legal action, or fraud allegations.
How long does a buyer have to cancel after receiving the disclosure?
Buyers have five business days after receiving the completed disclosure statement to revoke the transaction and recover their earnest money.
Do I need to disclose if someone died in the home?
No. Oregon law does not require disclosure of deaths occurring on the property.
Why is the final question on the OREF 020 important?
The final question asks whether there are any other material defects affecting the property or its value. You cannot answer “Unknown” and must provide an explanation if you answer “Yes.”
Final Thoughts
Seller disclosure in Oregon is more than a formality—it’s a critical legal and risk-management tool.
A properly completed OREF 020 protects both buyers and sellers by creating transparency and reducing the likelihood of disputes after closing.
Before listing your home, take the time to review the disclosure carefully and discuss any questions with your real estate professional.
