Cape Town's Affordable Housing Thresholds Exclude the Typical Household, Analysis Shows
Written on
A Development Action Group analyst writes that South Africa's competing definitions of affordable housing produce very different pictures of who is served, as Cape Town brings 1,000 homes to Granger Bay.
South Africa's competing definitions of affordable housing produce very different answers about who is actually being served, Luther Jubane, project coordinator at the Development Action Group, wrote in the Cape Argus, as Cape Town prepares to bring 1,000 homes for households earning up to R34,400 a month into the exclusive Granger Bay area.
Jubane noted that the universal benchmark holds that a household should not spend more than 30% of its gross monthly income on housing costs. The Financial Sector Code sets the upper income threshold for affordable housing at R34,400 gross household income a month, which at the 30% rule allows up to R10,320 in monthly housing costs and, on a mortgage at 11.5% over 20 years with 100% loan-to-value, roughly R968,000 of borrowing.
By contrast, the Centre for Affordable Housing Finance in Africa has historically defined affordable housing by price as homes costing less than R600,000, leaving a sizeable gap between the two definitions. Comparing those thresholds with actual earnings sharpens the point: Stats SA's 2023 Income and Expenditure Survey puts average household income at about R17,030 a month and median household income at R7,981.
Applying the same 30% benchmark to the median income yields only about R2,394 a month for housing, or a theoretical purchasing capacity of roughly R225,000, the article states. It notes a counterargument that the survey includes households with no income, and that Stats SA's Quarterly Employment Statistics put average gross monthly earnings in the formal non-agricultural sector at about R29,997 in 2026, much closer to the Financial Sector Code threshold, though that figure is an average rather than a median.
Jubane pointed to the Atlantic Seaboard, City Bowl and V&A Waterfront, where the median residential sale price reached about R8.35 million in the first half of 2026 and one-bedroom apartments rent for around R18,000 to R25,000 a month. He argued the Granger Bay scheme's value lies in broadening access to one of Cape Town's most exclusive locations, even though R34,400 is not an inclusive benchmark by national standards, and that the real test is whether these homes translate affordability into meaningful spatial inclusion.
