According to news24.com, the long-standing belief that South African law imposes a hard 10% ceiling on rent increases is a myth. The piece unpacks what the Rental Housing Act actually says and why the misunderstanding matters for small-scale landlords and tenants alike.
The Rental Housing Act, the primary legislation governing private rentals, does not prescribe a fixed percentage that a landlord may raise rent each year. Instead, it requires any increase to be “reasonable”, a term the Act defines as one that reflects market conditions, the cost of living and the landlord’s expenses. If a tenant disputes the amount, the matter can be taken to a Rental Housing Tribunal, an independent body that decides whether the proposed hike is justified.
For a property owner who rents out a single house or a few apartments, the absence of a statutory cap means they must balance the need to cover rising costs, such as electricity, water and maintenance, against the risk of losing tenants in a tight market. For tenants, the lack of a clear ceiling means they must stay alert to their lease terms and be prepared to challenge unreasonable increases through the tribunal process.
The confusion appears to stem from a series of public statements and media reports that loosely referenced a proposed 10% limit that never became law. The article notes that while the Department of Human Settlements has discussed rent-increase guidelines, no amendment to the Rental Housing Act has been enacted to enforce a numeric cap.
In the broader economic picture, South Africa is still grappling with double-digit inflation, which pushes many households to the brink of affordability. Small landlords, who often rely on rental income to service mortgages, feel the pressure to adjust rents in line with rising input costs. At the same time, tenants are increasingly aware of their rights under the Act and are more likely to contest hikes they deem excessive.
What this means for the property sector is that both sides need to be proactive. Landlords should document cost increases and communicate them transparently, while tenants should review their lease clauses and, if necessary, seek advice before accepting a new rent figure. The Rental Housing Tribunal remains the final arbiter when parties cannot reach an agreement.
What “reasonable” actually means in a rent dispute
When a Rental Housing Tribunal assesses whether a rent increase is reasonable, it weighs factors including the landlord’s documented cost increases, such as rates, levies, insurance and maintenance, against prevailing market rents for comparable properties in the same area, rather than applying any fixed formula. A landlord who can produce paperwork showing exactly what their costs have risen by is in a materially stronger position at a tribunal hearing than one who simply asserts that a higher rent is fair, which is the practical reason record-keeping matters as much as the increase figure itself. The Department of Human Settlements oversees the Rental Housing Act framework nationally, while each province runs its own tribunal to hear individual disputes.
The confusion over a mythical 10% cap is not unique to South Africa: several other jurisdictions have genuinely legislated rent caps in recent years in response to housing affordability pressure, which may be where the belief that South Africa has done the same originally took root, even though no such amendment has been made to the Rental Housing Act here.

Why the myth is so persistent despite never being law
A specific number is simply easier to remember and repeat than a qualitative standard like “reasonable”, which is very likely why a proposed figure that was floated in policy discussion but never enacted has outlived the discussion itself in public memory. The same pattern shows up elsewhere in consumer-facing regulation: a number attached to a policy debate tends to stick in public understanding long after the actual legislation that emerged looks nothing like the number that was originally discussed.
