Portland Real Estate Compliance Guide 2026
If you’ve spent any time looking at homes in the Rose City, you know the market here has a personality all its own. We have charming century-old bungalows, rainy winters that test every roof, and a unique set of rules that govern how we buy and sell property. Navigating real estate transactions in Portland means dealing with overlapping layers of compliance: you have state laws from Oregon, specific city ordinances from Portland, and federal regulations all mixing together.
For both buyers and sellers, understanding these rules isn't just about ticking boxes to make the lawyers happy—it’s about financial safety. Compliance is effectively risk management. For sellers, following the rules is your best shield against future lawsuits. For buyers, doing your due diligence is how you avoid turning your dream home into a money pit. As we settle into early 2026, the landscape has shifted slightly with new disclosure norms and team rules, so staying updated is critical whether you are listing a home in Laurelhurst or buying in St. Johns.
Essential Disclosures: What Sellers Must Reveal
The backbone of any safe transaction here is transparency. Oregon law is very protective of buyers, and that starts with the paperwork. The Oregon Seller’s Property Disclosure Statement is essentially the "constitution" of your sale. It covers everything from the condition of the roof and siding to the status of your water source, sewage system, and insulation.
If you are selling, you need to answer these questions honestly based on what you actually know. If you are unsure, it's better to say "unknown" than to guess and be wrong. For buyers, this document is gold. It tells you the history of the home’s hiccups.
This document carries real weight. Under Oregon law, if a seller fails to provide this statement, the buyer has a right to revoke their offer—meaning they can walk away with their earnest money—right up until closing. Even if the statement is provided, if the buyer disapproves of the disclosures, they generally have a five-business-day window to back out of the deal.
Beyond the standard form, you also have to consider material defects and federal rules. If a home was built before 1978, which applies to a huge chunk of Portland’s housing stock, sellers must comply with Lead-Based Paint disclosures. This gives buyers a 10-day window to conduct a specific risk assessment for lead, ensuring they know exactly what they are buying into.
Portland-Specific Compliance: Beyond the State Rules
While state laws cover the basics, the City of Portland adds its own flavor to the compliance mix. These local ordinances are often what trip up people moving from the suburbs or out of state.
First and foremost is the Home Energy Score. If you are listing a home publicly within Portland city limits, you must get this score before the listing goes live. It rates the home's energy efficiency on a scale of 1 to 10 and estimates energy costs. This score has to be included in all your marketing and ads. If you skip it, you could face fines of up to $500 every 90 days until it’s fixed.
Then there’s the issue of heating. Many older Portland homes still have heating oil tanks buried in the yard or sitting in the basement. If a tank is no longer in use, the fire code requires it to be emptied. However, most buyers (and their insurers) will want it decommissioned—filled with sand or slurry and capped—to prevent soil collapse or leaks. Similarly, if the home has a wood stove, it needs to be certified. Oregon DEQ rules state that uncertified wood stoves must be removed and destroyed upon sale. You can't just leave an old, dirty-burning stove for the next owner to deal with.
Finally, keep an eye on sewer lines. While the city doesn't mandate that you fix an old sewer line to sell a house, a sewer scope is standard due diligence here. You may also run into "party sewers," where multiple homes share a single line to the main. These often require specific legal agreements to ensure everyone knows who pays for what if a clog happens.
Managing Physical & Financial Risks
In Portland, physical risks quickly turn into financial ones. Because so many of our homes were built between the 1900s and the 1970s, they often pre-date modern safety codes.
Seismic safety is a major talking point. Homes built before 1993 usually aren't bolted to their foundations. In the event of a significant earthquake, these homes can slide right off. For buyers, checking for seismic retrofitting documentation isn't just about safety; it’s about insurability. Many insurance carriers are getting stricter about covering older, unbolted homes.
You also need to think about what’s in the ground and air. Radon is surprisingly prevalent here, especially along the Alameda Ridge and other rocky areas. It’s an invisible gas that causes lung cancer, and testing for it is a standard contingency in almost every purchase offer. If levels are high, mitigation systems typically run between $1,500 and $2,500.
Underground risks include those oil tanks mentioned earlier. Underground Storage Tanks (USTs) that leak can contaminate the soil, leading to cleanup costs that can sometimes exceed the value of the property itself. Never assume a tank is fine; always ask for the decommissioning certificate or soil samples.
Lastly, check the permit history on Portland Maps. It is common to find finished basements or Accessory Dwelling Units (ADUs) that were done without permits. Buying unpermitted work is a risk—the city can force you to tear it out or pay to bring it up to current code, which can be astronomically expensive.
Agency Duties and Fair Housing Compliance
Compliance isn't just about the building; it's about the people and the process. Real estate agents are bound by strict agency duties, including loyalty, confidentiality, and the duty to disclose material facts.
As of early 2026, you might notice new requirements regarding how real estate teams market themselves. These rules are designed to increase transparency so consumers know exactly who represents them and who is responsible for the file.
Fair Housing laws are another critical area where Oregon goes further than federal law. While federal law protects classes like race, religion, and sex, Oregon adds protections for marital status, sexual orientation, gender identity, and Source of Income. This last one is huge—it means sellers and landlords cannot discriminate against buyers or tenants using Section 8 vouchers or other assistance programs.
This extends to advertising, too. We have to be very careful to avoid coded language. You won’t see listing descriptions saying a neighborhood is "perfect for families" or an "exclusive community." Instead, we focus on the features of the property and the area—mentioning that a home is "near parks," has a "fenced yard," or is located on a "quiet street." This ensures everyone has equal access to housing information.
The Closing Process: Title, Escrow, and Good Funds
Once you’ve navigated the inspections and disclosures, you arrive at closing. This is where the financial safeguards kick in.
Title insurance plays a massive role here, especially with our older properties. It protects you against hidden liens, boundary disputes, or long-lost heirs claiming ownership. In a city where property lines can be fuzzy due to old surveys, this policy is essential.
In Oregon, we use Escrow as a neutral third party. They don't work for the buyer or the seller; they work for the contract. They hold the documents and the money until every single condition of the sale is met.
When it comes time to pay, you need to know about the Good Funds Law. You cannot simply write a personal check at the closing table. Oregon requires funds to be "collected" before the deed is recorded and money is disbursed. In practice, this means you need to wire your down payment and closing costs or bring a cashier's check. If you try to pay with a personal check, the transaction will grind to a halt until that money clears, which can delay possession and cause a breach of contract.
Practical Compliance Tips for Buyers and Sellers
If you want to sleep easy during a transaction, a little preparation goes a long way.
For sellers, the best move is to pre-inspect. Don't wait for the buyer to find the radon issue or the broken sewer line. If you deal with major risks like tank decommissioning or seismic retrofitting before you list, you avoid mid-transaction panic and price renegotiations.
For buyers, the golden rule is never to waive the inspection contingency on an older home unless you have massive cash reserves. There are just too many variables in a 1920s Portland home to fly blind.
For both parties, lean on the advisory documents. Your agent should provide a "Buyer Advisory" or "Seller Advisory." These aren't just junk mail; they are checklists of common pitfalls and local resources. Read them.
FAQs on Portland Real Estate Compliance
Is a Home Energy Score required to sell a house in Portland?
Yes, if your home is within Portland city limits and is publicly listed, you must obtain a Home Energy Score before marketing the property. Failing to include the score and report in your listing can result in fines from the city.
What happens if a seller doesn't provide the Property Disclosure Statement in Oregon?
If a seller fails to provide the disclosure statement, the buyer has the right to revoke their offer and walk away with their earnest money at any time prior to closing. It essentially gives the buyer an unending exit clause until the transaction is finalized.
Do I have to remove my oil tank before selling my house in Portland?
You are required to empty an unused tank to comply with fire codes, but full removal or decommissioning (filling and capping) is not strictly a legal mandate for the sale itself. However, because most insurance companies won't cover a home with an active risk like an old tank, decommissioning is effectively a market requirement to get the deal closed.
Are sewer scopes mandatory in Portland real estate transactions?
A sewer scope is not a legal mandate, but it is considered standard due diligence. Given the age of Portland's infrastructure and the high cost of repairs, skipping a sewer scope is a significant financial risk that most buyers should not take.
What are the protected classes for fair housing in Oregon?
In addition to federal protections like race, religion, and national origin, Oregon protects individuals based on marital status, sexual orientation, gender identity, and source of income. This means sellers cannot refuse to sell to someone because they are using housing assistance or vouchers.
