Housing Security Is Healthcare: How Eviction Prevention Programs Are Saving Lives and Cutting Emergency Room Costs in America's Most Vulnerable Communities

Every year, more than 3.6 million eviction filings are processed through American courts. Behind each case number is a family—often a single mother with young children, an elderly renter on a fixed income, or a household already managing a chronic illness—facing a cascade of consequences that extend far beyond the loss of a home. Displacement fractures routines, severs connections to medical providers, disrupts children's schooling, and plunges individuals into the kind of sustained physiological stress that accelerates disease and shortens lives.

For too long, eviction has been framed as a legal matter or an economic one. The evidence now compels a different framing entirely: eviction is a public health emergency, and preventing it is one of the most cost-effective health interventions a community can make.

The Body Keeps the Score of Housing Instability

The relationship between unstable housing and deteriorating health is not incidental. It is causal, documented, and increasingly quantifiable. A landmark study published in the American Journal of Epidemiology found that eviction significantly increased the likelihood of adverse mental health outcomes, including depression, anxiety, and suicidal ideation, among low-income mothers. Separate research from Princeton University's Eviction Lab has linked eviction history to elevated rates of hospitalization, particularly for conditions such as asthma, hypertension, and diabetes—illnesses that are profoundly sensitive to environmental stress and disruption of care.

When a family is evicted, their access to a regular primary care provider often evaporates. Prescriptions go unfilled. Follow-up appointments are missed. Children fall behind on vaccinations. Adults managing chronic conditions lose the continuity of care that keeps those conditions from escalating into emergencies. The result is a predictable surge in emergency department utilization—the most expensive and least effective form of medical care for conditions that could have been managed in a clinic.

A 2019 analysis conducted across multiple US cities estimated that each eviction generates between $30,000 and $90,000 in downstream public costs, including shelter stays, emergency medical services, child welfare interventions, and lost school days. These are not abstract figures. They represent real expenditures absorbed by local governments, hospital systems, and social service agencies that are already stretched thin.

Eviction Prevention as Public Health Infrastructure

The good news—and there is genuine good news here—is that a growing body of evidence demonstrates that targeted eviction prevention interventions dramatically reduce these downstream harms at a fraction of the cost.

Emergency Rental Assistance (ERA) programs, accelerated during the COVID-19 pandemic, provided one of the most significant natural experiments in housing stability policy in American history. Data from the National Low Income Housing Coalition and multiple state-level analyses found that ERA programs not only prevented millions of evictions during the pandemic period but were associated with measurable reductions in emergency room visits and mental health crisis calls in communities where funds were distributed effectively. In Philadelphia, researchers found that neighborhoods with higher ERA uptake saw statistically significant drops in stress-related emergency department presentations compared to similar neighborhoods with lower program participation.

Right-to-counsel programs, which guarantee legal representation to tenants facing eviction, have demonstrated equally compelling outcomes. New York City, which implemented one of the country's most comprehensive right-to-counsel initiatives, reported that represented tenants were more than twice as likely to remain in their homes compared to those who navigated proceedings without legal help. San Francisco and Cleveland have reported comparable results. When tenants have access to legal advocates, the power imbalance inherent in landlord-tenant court proceedings is partially corrected—and families are far more likely to reach negotiated agreements that preserve their housing.

Community mediation programs represent a third pillar of effective prevention. By facilitating structured dialogue between landlords and tenants before cases reach the courthouse, these programs resolve disputes related to rent arrears, maintenance failures, and lease misunderstandings in ways that preserve the tenancy and often benefit landlords as well—avoiding the cost and delay of formal legal proceedings. Mediation programs in cities including Denver, Baltimore, and Louisville have reported resolution rates exceeding 70 percent, with the majority of agreements allowing tenants to remain housed.

The Mental Health Dividend

Perhaps the most underappreciated dimension of eviction prevention is its impact on mental health. Housing instability is a chronic stressor that activates the body's threat-response systems in ways that, over time, compromise immune function, cardiovascular health, and neurological development in children. The psychological toll of receiving an eviction notice—even one that is ultimately resolved—has been shown to produce cortisol spikes and anxiety symptoms comparable to other major life traumas.

Children are particularly vulnerable. Research from Harvard's Center on the Developing Child confirms that housing instability during early childhood disrupts the formation of secure attachment, impairs executive function development, and increases the likelihood of behavioral and learning difficulties that persist into adolescence. When communities prevent an eviction, they are not simply keeping a family in an apartment. They are protecting the neurological architecture of the next generation.

For adults, the mental health benefits of housing security are equally significant. Studies examining participants in subsidized housing programs consistently find reductions in depression and anxiety scores following placement in stable housing. Community health workers who operate in high-eviction neighborhoods frequently report that stabilizing a family's housing situation produces immediate, observable improvements in parental functioning, social engagement, and adherence to medical treatment plans.

What Communities Can Do Right Now

Eviction prevention is not a passive aspiration. It is an active, organizational commitment that communities can pursue through concrete channels.

Local governments can establish or expand emergency rental assistance funds with streamlined application processes that reach tenants before a crisis becomes a filing. Tenant-facing hotlines staffed by trained housing counselors can identify households at risk and connect them to resources before a landlord ever initiates court proceedings.

Healthcare systems—hospitals, federally qualified health centers, and community health organizations—can integrate housing instability screening into routine patient intake. Tools such as the PRAPARE assessment protocol already allow clinicians to identify patients at risk of eviction and refer them to legal aid or assistance programs. When a patient presenting with uncontrolled hypertension is also identified as facing eviction, treating only the blood pressure while ignoring the underlying housing crisis is, in effect, incomplete medicine.

Tenant advocacy organizations and legal aid societies require sustained, meaningful funding. Right-to-counsel programs do not run on goodwill. They require attorneys, paralegals, and administrative infrastructure—investments that consistently return many times their cost in reduced public expenditures.

Finally, faith communities, neighborhood associations, and mutual aid networks can play a critical early-warning role, identifying neighbors who are struggling before a situation reaches the point of formal legal action.

The Moral and Economic Case Are the Same Case

At Healthy Homes Collaborative, we hold a foundational conviction: that safe, stable housing is not a luxury or a reward for economic success. It is a prerequisite for human health and dignity, and its provision—or its absence—is a choice that communities make, consciously or not, through their policies and their resource allocations.

Eviction prevention programs are not charity. They are, by any rigorous cost-benefit analysis, among the most efficient public health investments available to American communities. Every dollar spent keeping a family housed is a dollar that does not have to be spent on emergency shelter, emergency medicine, child welfare proceedings, or the compounding social costs of a generation raised in instability.

The data is clear. The interventions exist. What remains is the political and communal will to treat housing security with the same urgency we bring to any other public health crisis—because that is precisely what it is.
