Social interaction is the process in which people interact each other and has value to maintain the wellbeing of the human beings. Ethiopians are well known for their social interaction, due to expansion of urbanization and shortage of houses, building condominium houses is likely to reduce the problem. Though there is positive impact living in the area, it affects the social interactions of the residents due to lack of proper entertainment facilities. This study examines the status of social interaction at condominium residents in Bahir Dar City Administration at Ginbot-20 sub-city preparatory site. The study employed qualitative approach and case study design method and data were collected using in-depth from 9 residents from which 4 are females and 5 are males and key informant interviews from 5 persons who are male. The data is collected from November 15/2009 to December 25/2009 EC and it is analyzed thematically. The findings demonstrated that even though living in condominium houses have good opportunities to strengthen interaction among residents, account of social interaction, the physical structure, awareness how to live in these areas, turnover of residents, the value and understanding of social interaction by residents and the heterogeneity of the people living there has threatened residents’ social interaction. Besides, there are opportunities such as free space, the structure of the houses and the people themselves are considered as good opportunities which can contribute positively. The paper concludes that social interaction in this area is weak and needs special attention to rehabilitate social ties. The concerned bodies i.e, Amhara House Development Enterprise has big responsibility in facilitating open spaces during planning and building houses; similarly social workers should advocate the issue to get attention of the public and government.
