You’ve found the perfect house online. You love the kitchen photos, the backyard looks great—and then you spot the floor plan. Suddenly, you know exactly where the kids’ rooms could go, whether your sofa will fit, and if that “open concept” claim is actually true.
But here’s the surprising part: who owns that floor plan—and whether a real estate agent can legally use it—can become a copyright issue.
A 2025 federal appeals court decision brought some important clarity to the question, and its implications are still relevant to real estate professionals in 2026.
In Designworks Homes, Inc. v. Columbia House of Brokers Realty, Inc., the U.S. Court of Appeals for the Eighth Circuit considered whether real estate agents could create and publish floor plans of existing homes when the underlying architectural designs were copyrighted. The court ultimately held that, under the specific circumstances of the case, the agents’ use qualified as fair use. (copyright.gov)
So, why did the agents get the green light?
They weren’t using the plans to build another house. Instead, they created simplified floor plans to help prospective buyers understand and evaluate homes being offered for resale. The court considered that a different, informational purpose from the original architectural designs.
The court also weighed the other fair-use factors, including the nature of the copyrighted work, how much of the original design was used and whether the use could harm the copyright owner’s market. In this case, the court concluded that fair use applied. (ecf.ca8.uscourts.gov)
But there’s an important “don’t get too comfortable” here.
This decision does not mean every floor plan is automatically fair game. The U.S. Copyright Office explains that fair use is determined on a case-by-case basis. There isn’t a magic percentage or amount that automatically makes copying legal. (copyright.gov)
For real estate professionals, the 2026 takeaway is straightforward: using a floor plan to help market a home may qualify as fair use in circumstances similar to this case, but the details matter.
So the next time you see a floor plan tucked beneath those listing photos, remember: those little boxes and lines may look simple—but legally, there can be a lot more to the picture.
