If you’ve sold a home in Portland recently, you’ve dealt with a Home Energy Score. If you’re selling in Bend, Hillsboro, or Milwaukie, same story. For everyone else in Oregon — it’s coming up more and more, even where it isn’t required yet.  The program has some pros and cons.  At it’s inception it seemed like a good idea, by the time it launched, it became a data collection tool and a hoop jump that buyers and sellers have little use for (for the most part).

 

Here’s what you actually need to know.

 

What Is a Home Energy Score?

A Home Energy Score is a 1-to-10 rating of how energy efficient your home is. A 10 is highly efficient. A 1 means the house uses a lot of energy relative to its size and systems. The score is based on the home’s structure, insulation, windows, heating and cooling equipment, and water heater — not your utility bills.

 

A licensed assessor does the evaluation in person. It takes roughly two hours and costs between $150 and $300. The report is valid for eight years, with a two-year refresh option if you make improvements.

 

The score comes with an estimated annual energy cost and recommendations for upgrades — insulation, weatherization, heat pump conversion, and so on. Those recommendations are informational. Nobody requires you to act on them.

 

Where It’s Required in Oregon

Oregon has a statewide framework for home energy disclosure (ORS 469.703), but no statewide mandate. The cities that have moved ahead on their own:

 

Portland — Required at time of listing for most residential sales. Has been in effect since 2018.
Bend — Required at listing.
Hillsboro — Required at listing.
Milwaukie — Required at listing.

 

If you’re selling in one of these cities, you need a current score before the home goes on market. If you don’t have one, we schedule the assessment as part of our pre-listing prep.

 

Cities Watching Closely

Eugene, Corvallis, Ashland, and Hood River have all had active conversations about adopting similar requirements. None have mandated it yet. That could change — and sellers in those markets should be aware it may become a condition of sale in the not-too-distant future.

 

Salem does not currently require a Home Energy Score. No mandate is pending as of this writing.

 

What About the Rest of the Country?

Oregon isn’t alone. Austin, Boulder, Santa Fe, and Minneapolis have energy disclosure requirements in some form. Massachusetts has a statewide program. The policy momentum is real — it tends to start in cities with strong sustainability agendas, then spread.

 

Whether Oregon eventually adopts a statewide rule is an open question. The framework already exists. The political will hasn’t fully arrived.

 

Where the Score Works — and Where It Doesn’t

The Home Energy Score does a reasonable job of what it was designed to do: compare homes of similar size to give buyers a sense of relative operating costs. If you’re choosing between two similar houses and one scores a 4 and the other scores an 8, that’s useful information. The lower-scored home will likely cost more to heat and cool.

 

Where it falls short is the square footage problem. The score accounts for size as part of its calculation — and that creates situations where a large, well-built home scores lower than a small, less efficient one. Not because the large home is poorly constructed, but because it uses more energy by nature of being larger.

 

We had this experience firsthand. Our home scored a 9. Then the methodology changed to more heavily weight square footage. Our score dropped to a 7. Nothing about the house changed. The math did.  Buyers aren’t comparing a 2000 SQFT home to a 4000 SQFT home, they are comparing two homes of like size.  Large homes play on a compressed scale, hiding the actual efficiency, or lack of, a home.

 

That’s not a reason to dismiss the score entirely — but it is a reason to read it in context, not in isolation.

 

The Real-World Reality

In ten-plus years of selling Portland homes under this requirement, we haven’t had a single buyer use the Home Energy Score as a deciding factor.

 

That doesn’t mean it’s useless — it means buyers weigh it the same way they weigh a lot of disclosure information: as one data point among many, not a dealbreaker. Location, condition, price, and layout consistently outrank energy efficiency in the decision.

 

Sellers sometimes worry a low score will hurt their sale. In our experience, it rarely does — unless the score is revealing something else, like aging HVAC or poor insulation that buyers would have noticed anyway during inspection.

 

What Sellers Should Do

If you’re in a city where a score is required, get it early. Don’t wait until you’re under contract. Schedule the assessment during your pre-listing phase so there are no surprises and no delays.  If you bought your home in the last eight years, go to the registry and check to see if there is an existing report that you can use.  There’s no point in paying for a new one.  Substantial remodels and updates to systems make this moot.

 

If your score comes back low and you want to improve it before listing, the assessor’s report will tell you exactly which upgrades move the needle most. Some — like attic insulation — are relatively affordable and can shift the score meaningfully. Others, like full HVAC replacement, may not pencil out before a sale.

 

We can help you think through what’s worth doing and what isn’t. That’s part of the pre-listing conversation we have with every seller.

 

What Buyers Should Know

Ask for the Home Energy Score report, not just the number. The full report includes the estimated annual energy cost and the breakdown by category — heating, cooling, water heating. That’s more useful than the score alone.  One use may be a roadmap of what projects you might choose to focus on in the future.

 

If you’re buying in a city that doesn’t require a score, you can still request one or order it yourself. It’s a few hundred dollars and two hours for a home assessor to walk the property. Worth it if you’re seriously considering a home with older systems or you just want the data.  It’s usually done as part of a remodel project.

 

And if you’re comparing two homes — one scored, one not — don’t let the absence of a score on the second home be a black mark. It may simply be in a city where disclosure isn’t required yet.
