One of the global urban sustainability hitches of housing for internally displaced persons in the Third World countries had been revealed by unsustain urbanization, violence insecurities, institutional lapses and environmental changes. This paper seeks to examine the housing facilities challenges for internally displaced persons using Bonaberi, a cosmopolitan urban area of Douala. A sample of 281 households was used to represent the entire population of Bonaberi. Stratified random sampling technique was used to map out the appropriate location of internally displaced households. Results were analysed using Statistical Package for Social Science Standard (SPSS version 23.0) and presented in the form of tables, figures and plates. Results revealed diverse demographic and socio-economic profile amongst internally displaced households in Bonaberi. Despite their diverse housing features, conditions and services patterns, unsustain urbanization, urban planning deficiencies and coordination continue to prevail resulting to acute overcrowding, limited accessibility and services deliveries, pollution and disease proliferations. Although, diverse stakeholders’ alternative housing facilities strategies exist for emerging internally displaced persons, there were ineffective due to weak policies, language barriers, stigmatization among others. Therefore, there is the need for low-cost and affordable housing schemes for emerging internally displaced households, services optimization, extension, investment and employment in additions to capacity building, empowerment, local participation, advocacies and social inclusion for better housing standards. Also, ensuring effective policy implementations, technology, coordination and collaboration could enhance the overall living standards of IDPs and host communities in Bonaberi and other Third World Cities.
