This chapter examines some of the experiences of various policies upon access. The main ideological push in the direction of state-sponsored self-help housing occurred during the late 1950s and 1960s when social welfare and urban development were becoming of concern to Third World national governments and international development agencies. Conventional policies are those which promote housing projects constructed by the building industry through state subsidies and no self-help efforts, such as those, until recently, implemented in India by the state housing boards as the most popular form of policy. The denial of access to government or conventional housing for the poor during the 1960s is reflected in the way in which the literature of that time began to focus upon illegality. Cross-cultural studies on Asian, African and Latin American contexts have offered scope for comparative analysis of the unregulated housing sub-markets.
