Single-Family Zoning: America's Housing System That Feudal Lords Would Recognize

In 1926, a small Ohio village convinced the Supreme Court that apartment buildings were “parasites,” enshrining a legal doctrine that has since locked millions out of homeownership. The case was Village of Euclid v. Ambler Realty Co., and the Court’s decision didn’t just validate zoning—it transplanted a feudal logic of land control into the legal architecture of American suburbs, where it remains firmly rooted today. The village of Euclid had zoned a parcel of Ambler Realty’s land for single-family homes only, blocking the company from building apartments and commercial structures. Ambler sued, arguing the ordinance effectively confiscated its property without compensation. The Supreme Court disagreed. In a now-infamous passage, Justice George Sutherland wrote that apartment houses “come very near to being nuisances” and are “a mere parasite, constructed in order to take advantage of the open spaces and attractive surroundings created by the residential character of the district.” The ruling held that a community could lawfully segregate land uses to preserve the “character” of a neighborhood—a concept that, upon inspection, looks less like public welfare and more like the manorial right to decide who belongs on the land. The legal reasoning in Euclid borrowed heavily from English common law doctrines of nuisance, which themselves evolved from feudal tenure systems where a lord’s control over his demesne was absolute. Under feudalism, the lord determined what could be built, who could reside, and under what conditions—not through building codes, but through the direct power to grant or withhold access to land. The common law of nuisance originally protected a landowner’s right to undisturbed enjoyment, a principle that easily mapped onto the lord’s interest in maintaining the order of his estate. When American courts adapted nuisance law to justify zoning, they resurrected a hierarchy that equated property value with social exclusivity. The feudal parallel isn’t merely rhetorical. In a medieval manor, the lord’s demesne—the land reserved for his own use—was ringed by lesser holdings where peasants worked strips of land in exchange for obligations. Today, single-family zones function as the modern demesne: vast swaths of urban and suburban land reserved for a single, high-cost use, while apartment dwellers and renters are pushed to the margins, often paying rents that function like a contemporary form of feudal dues to property owners. Zoning boards, composed of local homeowners, act as manorial courts, granting variances and special permits at their discretion, often in response to the interests of existing residents rather than the needs of those seeking entry. The data bear out the exclusionary impact. According to a 2022 report by the National Association of Housing and Redevelopment Officials, roughly 70% of residential land in major U.S. cities is zoned for single-family homes, effectively banning apartments. The Harvard Law Review noted in 2022 that density-reducing regulations—height limits, minimum lot sizes, prohibitions on accessory dwelling units—are among the strongest predictors of housing unaffordability. The Cato Institute’s 2023 paper “The New Feudalism” argues that such zoning is deliberately designed to keep lower-income households out of desirable neighborhoods, a conclusion echoed by an Annual Reviews article that same year documenting the racist and classist origins of low-density zoning. Proponents of zoning often defend it as a progressive reform born of the early 20th century to separate noxious industrial uses from homes. There is a kernel of truth there: early zoning did address genuine public health threats from factories and slaughterhouses. But the Euclid decision went far beyond that logic. It explicitly framed apartments themselves as a threat—not because they emitted smoke or noise, but because they brought people of lesser means into proximity with homeowners. The language of “parasite” reveals the underlying anxiety: the fear that property values, and the social status they encode, could be eroded by those who did not own land. A century later, the housing crisis is a direct outgrowth of this feudal inheritance. By restricting supply in the most opportunity-rich areas, zoning inflates prices, reinforces racial and economic segregation, and forces households into long commutes that undermine climate goals—a connection that policy analysts in energy and transportation fields increasingly recognize. The YIMBY movement has correctly identified zoning as the primary barrier to affordability and has pushed for deregulation to allow more housing. Yet a purely deregulatory approach risks ignoring the power dynamics embedded in the system. As a 2024 Wiley study on informal settlements suggests, simply removing formal zoning without complementary anti-displacement measures can leave the most vulnerable exposed to market forces they are ill-equipped to navigate. The feudal analogy clarifies the stakes. In a feudal order, land access is a privilege granted by the powerful, not a right. Dismantling that order requires more than streamlining permits or modestly upzoning a few corridors. It demands a fundamental shift from treating land as a private asset whose value must be protected for incumbents, to treating housing as a public good whose supply must meet regional need. That means moving toward state or regional frameworks that override local exclusionary zoning, coupling liberalization with robust tenant protections, inclusionary requirements, and direct public investment in affordable units. The Euclid decision gave American local governments a feudal toolkit disguised as a planning instrument. A century of exclusionary practice has shown that the tool works exactly as designed—to wall off opportunity and concentrate wealth. Understanding that lineage is not an academic exercise. It is the first step toward retiring a legal regime that has no place in a society that claims to value mobility and fairness.
