The right to housing is also mentioned in Article 28 of the Convention on the Rights of Persons with Disabilities, Article 16 of the European Social Charter (Article 31 of the Revised European Social charter) and in the African Charter on Human and Peoples' Rights. According to UN Committee on Economic, Social and Cultural Rights, aspects of right to housing under ICESCR include: legal security of tenure; availability of services, materials, facilities and infrastructure; affordability; habitability; accessibility; location and cultural adequacy. As a political goal, right to housing was declared in F. D. Roosevelt's 1944 speech on the Second Bill of Rights.
