Critics Say New Home Energy Requirement Could Burden Homeowners in Washington StateA new ordinance in Thurston County, Washington is drawing attention across the real estate industry after county leaders approved a requirement that homeowners in unincorporated areas obtain a Home Energy Score (HES) before listing their property for sale.
The policy is being promoted as a step toward improving energy transparency in the housing market. However, it has also sparked strong opposition from real estate professionals and home builders who argue it could create financial and logistical burdens for sellers.
This development is part of a broader conversation about housing policy, affordability, and regulatory oversight in Washington State.
WHAT IS THE HOME ENERGY SCORE REQUIREMENT?
Under the ordinance, homeowners in unincorporated Thurston County must obtain a Home Energy Score assessment before they can list their home for sale.
The score is intended to:
- Measure a home’s energy efficiency
- Provide transparency to potential buyers
- Support long-term climate and efficiency goals
Importantly:
- Homeowners are not required to make upgrades
- The rule does not change property tax assessments
WHY SUPPORTERS SAY IT MATTERS
Supporters of the ordinance argue that energy efficiency disclosure:
- Helps buyers understand long-term utility costs
- Encourages transparency in the real estate market
- Aligns with county climate mitigation goals
- Provides data for future sustainability planning
County officials frame the requirement as informational rather than punitive, aimed at improving market awareness rather than forcing renovations.
WHY CRITICS ARE CONCERNED
Real estate professionals and builders have raised several concerns about the policy:
Cost Burden on Homeowners
Some industry representatives estimate that energy efficiency upgrades required to meaningfully improve scores could cost $35,000–$40,000, particularly for older homes.
Impact on Home Sales
Critics argue that sellers may:
- Face reduced buyer interest
- Be forced into price concessions
- Experience lower net proceeds at closing
Legal Authority Questions
Some industry leaders question whether the county has the legal authority to impose additional seller requirements beyond existing Washington disclosure laws.
Impact on Older Housing Stock
Concerns have also been raised that older homes could be disproportionately affected, potentially widening gaps between new and existing housing inventory.
INDUSTRY RESPONSE
Real estate and construction professionals argue that the requirement places an additional layer of regulation on homeowners already navigating a complex market.
Industry representatives have emphasized that while energy efficiency is important, mandatory scoring systems may unintentionally:
- Slow down transactions
- Increase seller costs
- Create uncertainty in pricing strategy
WHAT THIS MEANS FOR WASHINGTON HOMEOWNERS
If similar policies expand beyond Thurston County, homeowners in King and Snohomish Counties may eventually see comparable requirements introduced.
For sellers, this highlights an important trend:
Real estate policy in Washington State is increasingly intersecting with energy, sustainability, and environmental regulation.
Understanding these changes early can help homeowners plan ahead for:
- Listing strategy
- Home preparation costs
- Timing of sale decisions
