Social finance and informal housing are becoming central to how South Africa can address its growing housing crisis. With a backlog of around 2.6 million homes, millions of people continue to live in informal settlements or backyard structures. Traditional housing delivery has not kept pace with demand, which has forced communities to create their own solutions. What is often overlooked is that this informal housing market is already functioning as an active economy, with small-scale landlords and developers generating steady rental income and meeting real demand.
Social finance focuses on using private capital to solve social problems while still generating returns. In the context of informal housing, this approach recognises that there is a viable market that has largely been excluded from formal financial systems. Many informal developers are unable to access funding due to a lack of formal documentation or collateral, despite running sustainable and cash-generating operations. This creates a gap where targeted financial models can unlock growth.
Blended finance has emerged as a practical solution. By combining concessional funding with commercial investment, it reduces risk while maintaining investor interest. This allows capital to flow into areas that would otherwise be considered too risky, enabling the expansion of affordable housing in a structured and scalable way. At the same time, there is a growing focus on measuring impact, with investors looking at outcomes such as housing delivery, job creation, and improved living conditions.
The challenge lies in scaling these solutions. Informal housing is not uniform, and each development comes with its own regulatory, social, and economic complexities. Flexible funding models are required to adapt to these conditions. Despite this, the opportunity remains significant. Informal housing is not just a social issue but a key part of the broader economy, linked to urban growth, employment, and financial inclusion.
There is a clear shift in how this sector is viewed. What was once seen purely as a problem is now recognised as an opportunity to deliver both economic returns and meaningful social impact.
