For decades, California has had one of the country’s largest
populations of unhoused people. In recent years, however,
the challenges have severely worsened for the Golden State.
The homelessness counts in California rose by 42 percent
between 2014 and 2020, while the rest of the country had a
9 percent decrease. On any given night, the state has more
than 160,000 homeless persons.

California’s homeless crisis is associated with high housing
costs, inadequate shelter spaces, deinstitutionalization,
and changes in the criminal justice system.

In 2016, the City and County of Denver launched the Denver Supportive Housing Social Impact Bond Initiative (Denver SIB) to shift resources from expensive emergency services to more permanent, affordable housing and supportive services. The initiative aimed to increase housing stability and decrease jail stays for people trapped in the homelessness-jail cycle. Funded by the Robert Wood Johnson Foundation’s Evidence for Action program, the Urban Institute launched a health outcomes study as a complement to the ongoing SIB evaluation. This report focuses on the year before people were enrolled in the SIB evaluation, giving us a picture of the status quo for health services in Denver for people experiencing cycles of homelessness and incarceration.

In 2016, the City and County of Denver launched the Denver Supportive Housing Social Impact Bond Initiative (Denver SIB) to shift resources from expensive emergency services to more permanent, affordable housing and supportive services that can be difficult to fund without up-front capital. The initiative aimed to increase housing stability and decrease jail stays for people trapped in the homelessness-jail cycle. This report details the costs of supportive housing provided by the Denver SIB and the costs and cost offsets associated with supportive housing’s effects on outcomes across the housing and homelessness assistance, criminal justice, and health care systems.

Homelessness is growing in communities across the United States as housing becomes increasingly unaffordable and public systems fail to support people who need assistance, forcing thousands to sleep outside or in shelters. Without access to housing and services, many people experiencing chronic, or long-term, homelessness are trapped in a homelessness-jail cycle—rotating in and out of jail, detoxification centers, and emergency health care. This cycle doesn’t help people access the assistance they need to find stability, and it comes at a major cost to taxpayers. Rather than paying for the consequences of leaving people in homelessness, communities could invest in housing and services that end this harmful pattern. Results from the five-year Denver Supportive Housing Social Impact Bond Initiative (Denver SIB) show how both people and public budgets benefit when communities take this proactive approach.ess, communities could invest in housing and services that end this harmful pattern.

  The Denver SIB, which provided supportive housing (a permanent housing subsidy and intensive services) to help participants stay housed, used a Housing First approach. Housing First programs don’t require participants to meet any preconditions, and they are built on the idea that secure, affordable, and permanent housing must be available before people can work on other challenges, such as mental health or substance use disorders. The Urban Institute, with partners from The Evaluation Center at the University of Colorado Denver, tracked implementation of the Denver SIB and evaluated its effects between 2016 and 2020. The evaluation used a randomized controlled trial, the gold standard for determining a program’s impact, that included 724 people: 363 people were in the treatment group (referred to the supportive housing program) and 361 people were in the control group (receiving services as usual in the community).

On Thursday, July 29th 2021, Los Angeles (LA) Mayor Eric Garcetti signed into law an ordinance amending Section 41.18 of the Los Angeles Municipal code (Spectrum 1 News, 2021). The series of amendments, proposed by LA City Council, reinstates prohibitions to “sit, lie, sleep, store, use, maintain, or place personal property upon any street, sidewalk, or other public right-of-way” in much of Los Angeles City, with particular enforcement around homeless services delivery sites, schools, parks, libraries, and underpasses (Shover et al., 2021; L.A.M.C. § 41.18, 2021). Violating these laws can carry fines for people experiencing homelessness (PEH) who refuse shelter and services, and authorizes forced removal if they do not voluntarily vacate encampments. Though the legislation includes a stated goal to prevent interactions between law enforcement and PEH and avoid arrest, advocates argue the ordinance will likely result in more contact between police and PEH (Zahniser & Oreskes, 2021). This legislation comes at the same time as residents and elected officials have renewed calls to re-examine the role police play in society, with a particular emphasis on the impacts of policing Black communities. Considering these public requests, the purpose of this paper is to examine findings from the literature on the types of policies that cause interactions between municipal and county law enforcement (referred to as police hereafter) and PEH, their outcomes, and the models and best practices being used by local governments to minimize negative outcomes

On any given night in the United States, more than 550,000 people are experiencing homelessness.1 Among these, approximately 96,000 are chronically homeless, meaning they are facing long and repeated episodes of homelessness that make it increasingly difficult to return to housing.2 This crisis is perpetuated by a legal system that criminalizes survival behaviors associated with homelessness, fails to account for the ways in which people who are homeless face impossible odds within the legal process, and then releases them back into the community with even more obstacles than they faced before.3 Confirming this cycle, researchers have found that homelessness is between 7.5 and 11.3 times more prevalent among the jail population, and in some places the rate is much higher—for example, in San Francisco, California, a 2013 survey found that between 10 and 24 percent of people in jail identified as homeless at the time of arrest.4 Because of punitive laws and enforcement practices, people who are homeless are 11 times more likely to be arrested, nationwide, than those who are housed.

Police often are the first (and sometimes the only) point of government contact for persons experiencing homelessness (PEH). Although it has been common for police to rely on traditional law enforcement powers in dealing with homelessness, many agencies have moved away from arrest-focused methods in favor of approaches that are designed to foster positive relationships with PEH, assess individual needs of each person or area, and guide homeless or unsheltered individuals to the services they require.

To better understand the potential challenges of the law enforcement response to homelessness, the RAND Corporation and the Police Executive Research Forum, on behalf of the National Institute of Justice, convened a workshop of practitioners and researchers to discuss current law enforcement responses to homelessness and identify the highest-priority needs to support and improve existing efforts. During this meeting, four major themes were identified. First, there is a common set of factors underlying homelessness that law enforcement can address. Second, homelessness and overall health and wellness are deeply intertwined issues that should be treated together. Third, effective responses require the collaboration of stakeholders across governments, the private sector, and the community. Finally, acquiring and sharing data is necessary to understand the nature and scope of homelessness in each jurisdiction and to measure the effect of any implemented strategies. All four of these themes are vital to understanding the current challenges confronting the implementation of innovative police responses to homelessness.

Recent nationwide protests against police use of force and perceptions of systemic racism in law enforcement in the United States have sparked renewed conversation about problems in the U.S. criminal justice system. Much of this conversation has been focused on the idea of "defunding the police." In this Perspective, the authors describe police leaders' and practitioners' views on defunding the police — that is, budgeting less money for police and more for other public safety strategies — and explain why revisiting the role of law enforcement in society could have broader appeal than some think. To do this, the authors draw on experience in workshops held over the past seven years by the Priority Criminal Justice Needs Initiative. In these workshops, police leaders and practitioners have voiced frustration with being the default party that is expected to respond to many complex social problems, such as homelessness, substance use, and mental health crises. Practitioners argue that nonenforcement strategies are often more effective than policing in solving many of these problems. Therefore, the authors suggest that there might be significant law enforcement support for some "defunding" strategies — as long as these efforts relieve some of the unrealistic expectations on police. The authors also describe current police functions that could be reassigned to other community partners, discuss factors that communities must consider if they choose to reallocate police functions, and note evidence of broader support for such reforms in the general population.

This guide addresses homeless encampments, also known as transient camps. It begins by describing the problem and reviewing factors that contribute to it. It then identifies a series of questions to help you analyze your local problem. Finally, it reviews responses to the problem and what is known about them from evaluative research and police practice. Homeless encampments are only one aspect of the larger set of problems related to homelessness, street life, and public disorder.
