Article 25 of the Universal Declaration of Human Rights, adopted 10 December 1948 by the UN General Assembly, contains this text regarding housing and quality of living:

Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing, and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control. The ETHOS Typology of Homelessness and Housing Exclusion was developed as a means of improving understanding and measurement of homelessness in Europe, and to provide a common "language" for transnational exchanges on homelessness. The ETHOS approach confirms that homelessness is a process (rather than a static phenomenon) that affects many vulnerable households at different points in their lives.The typology was launched in 2005 and is used for different purposes: as a framework for debate, for data collection purposes, for policy purposes, monitoring purposes, and in the media. This typology is an open exercise that makes abstraction of existing legal definitions in the EU member states. It exists in 25 language versions, the translations being provided mainly by volunteer translators. Despite all the international agreements and efforts, many countries and individuals in power do not consider housing as a human right. Former US President, Jimmy Carter, addressed this issue in a 2017 interview.
He said, “A lot of people dont look at housing as a human right, but it is.” His view contrasts with many American, especially those in power, that do not believe this right is inline with the US constitution. Other terms
Recent homeless enumeration survey documentation utilizes the term unsheltered homeless. The common colloquial term street people does not fully encompass all unsheltered people, in that many such persons do not spend their time in urban street environments. Many shun such locales, because homeless people in urban environments may face the risk of being robbed or assaulted. Some people convert unoccupied or abandoned buildings ("squatting"), or inhabit mountainous areas or, more often, lowland meadows, creek banks, and beaches. Many jurisdictions have developed programs to provide short-term emergency shelter during particularly cold spells, often in churches or other institutional properties. These are referred to as warming centers, and are credited by their advocates as lifesaving. History
Early history through the 19th century
United Kingdom
Following the Peasants Revolt, English constables were authorized under 1383 English Poor Laws statute to collar vagabonds and force them to show support; if they could not, the penalty was gaol. Vagabonds could be sentenced to the stocks for three days and nights; in 1530, whipping was added. The presumption was that vagabonds were unlicensed beggars. In 1547, a bill was passed that subjected vagrants to some of the more extreme provisions of the criminal law, namely two years servitude and branding with a "V" as the penalty for the first offense and death for the second.
