The low-income communities face the constraints in building adequate housing, particularly in the developing world, are often formidable and intractable, deeply linked to political and economic order as well as to social structure. The lack of available and accessible housing problems has been identified by the Government of Bangladesh (GOB) as one of the important hurdles in improving the housing conditions for middle and lower income households (Marja C. 1998). In this paper, these constraints are discussed and some of the approaches to redress them are reviewed. The principle methodological tool is a review of relevant literature. Three main types of constraints are identified: financial resource constraints, hazard vulnerability and natural resource scarcity. In this paper, it is not attempted to present a prescription for problem remedy. Nonetheless, identification and developing understanding of the constraints could perhaps serve as an initial step towards informing policy and practice. The present study builds on these efforts and attempts to formulate recommendations for improving access to housing credit for various groups of presently underserved urban and rural households.
