A Washington Court of Appeals ruling has allowed GRE Downtowner LLC to pursue claims that Seattle rental regulations effectively took private property without compensation. The dispute concerns Addison on Fourth, a 254-unit apartment complex operated as affordable housing. The court’s decision lets the claims proceed; it does not establish that the city violated the Constitution or owes damages.

GRE alleges that a series of Seattle rules made the investment financially unsustainable. The company’s claims include an ordinance requiring landlords to accommodate certain additional occupants, even without the landlord’s consent. Other measures cited in court filings restricted criminal-background screening and some evictions and required relocation assistance after qualifying rent increases.

The property participated in the federal Low-Income Housing Tax Credit program. That program uses tax incentives to attract private investment in rental housing with income-based rent restrictions. Sean Flynn, executive director of the Rental Housing Association of Washington, said such projects can have limited operating profits, with the tax credits helping make them attractive to investors. Flynn is working with GRE in its case against Seattle.

According to court filings described in the source material, Addison on Fourth generated positive cash flow from 2015 through 2018. GRE says collections fell from 93.9% in 2018 to 44.1% in 2023 as the city enacted the regulations, and that the property accumulated nearly $5.8 million in operating losses. A federal judge appointed a receiver in January 2026 after a mortgage default, transferring control of the property to the receiver.

Flynn argued that Seattle’s rules discouraged investment and could reduce housing options for renters. He characterized the combined measures as a “toxic cocktail of legislation.” Those statements reflect Flynn’s position, rather than a finding by the appeals court. The source material does not provide a response from Seattle addressing the underlying allegations.

The legal claim is based on inverse condemnation, a doctrine through which property owners may seek compensation when they contend government action has effectively taken or damaged their property without just compensation. GRE argues that Seattle’s ordinances, considered separately and together, substantially restricted its property rights. The appellate ruling permits the company to continue litigating that theory; the ultimate merits and any compensation remain unresolved.

Ilya Somin, a George Mason University law professor specializing in constitutional law and property rights, described the decision as more consequential than a routine procedural ruling, while cautioning that its broader effect should not be overstated. He said courts elsewhere could consider it in similar disputes and that a U.S. Supreme Court case was possible, though unlikely. Somin also said he believed GRE’s challenge to the roommate provision had merit.

In discussing that provision, Somin pointed to the U.S. Supreme Court’s decision in Cedar Point Nursery v. Hassid. That case concerned a California rule requiring agricultural employers to allow union organizers onto private property; the court found a physical taking under the Fifth Amendment. Somin said Seattle’s requirement to accommodate additional occupants raises a related constitutional question. That comparison is his legal analysis, not a determination that the Seattle rule is unconstitutional.

The Seattle City Attorney’s Office told Fox News Digital it was reviewing the appellate ruling. Chief of Staff Dan Nolte said the office had not decided whether to appeal.

The dispute comes amid varied landlord and tenant regulations in other cities. The source material cites rent controls and eviction limits in San Francisco, New York’s 2024 expansion of protections under the state’s Good Cause Eviction law, Portland rules on criminal-history screening and relocation payments, and Philadelphia restrictions on criminal-history screening. The cases and policies are not identical, and the Seattle ruling does not decide the legality of those other cities’ measures.
