Human Rights, including the rights to adequate housing and safe water and sanitation are contained in the Universal Declaration of Human Rights and international human rights instruments, including the International Covenant on Economic, Social and Cultural Rights which have been ratified by most UN Member States. These rights, once so endorsed, do not have a voluntary character. They impose obligations on states and on the international community, they are universal, cannot be waived or taken away, and are legally protected. The Universal declaration of Human Rights (UDHR) refers to adequate housing in article 25. The International Covenant on Economic, Social and Cultural Rights (ICESCR) also refers to the same in article 11.
