The responsibility for building community resilience cannot and should not rest with the public sector alone. It requires all sectors to collaborate for the benefit of the entire community. Specifically, it is important for private sector organisations to participate in building community resilience because they have vested interest in the area because of their physical assets, suppliers, customers and corporate value of social responsibility. This article explores collaboration between private companies and community of Diepsloot, Johannesburg, South Africa, to build disaster resilience in the community. The study applied qualitative research methods. Data were collected through focus group interviews with the community of Diepsloot and semi-structured individual interviews with representatives of private companies operating in the vicinity of Diepsloot. A total of 55 respondents participated in the study. Respondents included five corporate social responsibility (CSR) managers from private companies and 50 community members. The findings of the study showed that private companies are involved in addressing socio-economic challenges in Diepsloot. Addressing such challenges contributes a great deal to reducing exposure to hazards and the vulnerability factors to disasters, thereby contributing to building resilience. Whereas some respondents preferred the private companies to work with the communities directly, the study recommends the use of community structures such as Community Based Organisations (CBOs) when private companies engage in community initiatives. The article contributes to better understanding of the private sector’s contribution to build community resilience.
