Section 26(2) of the Constitution requires the state to devise and implement, within its available resources, a comprehensive and coordinated programme to progressively realise the right of access to adequate housing. The test is whether the legislative and other measures adopted by the state are reasonable. A reasonable programme must be balanced and flexible, make appropriate provision for housing crises and for short, medium and long-term needs, be capable of facilitating the realisation of the right, and be reasonably implemented. A programme that excludes a significant segment of society, particularly those whose needs are most urgent, cannot be reasonable. The state's housing programme must include reasonable measures to provide relief for people who have no access to land, no roof over their heads, and who are living in intolerable conditions or crisis situations. Section 28(1)(c) does not create an independent obligation on the state to provide shelter to children and their parents on demand; the primary obligation rests with parents and families, with the state's obligation arising when children lack family care.
