Commercial Property hits rent escalation ceiling

• Over 50% of tenants reject rental escalations above 4%, signalling a structural affordability ceiling across the commercial sector.
• “Neutral” tenants pose the biggest renewal risk,  compliant today, but ready to exit at renewal.
• Technology, flexibility, and landlord-tenant partnerships are now critical to sustaining occupancy and income.

A market hitting its limits‍

South Africa’s commercial property sector is facing a hard reset. The latest TPN Credit Bureau’s 2026 Voice of the Commercial Tenant Report reveals that the market has reached an escalation ceiling, where traditional rental growth models are no longer viable.

More than half of tenants indicate that annual rental increases above 4% are unsustainable, a stark shift from historic escalation norms of 6% to 8%.

This is not a cyclical slowdown. It’s a structural change driven by rising operating costs, economic pressure, and a growing mismatch between landlord expectations and tenant affordability.

‍

Waldo Marcus, Director at TPN Credit Bureau, puts it bluntly: “We’re seeing a fundamental shift in affordability. The old escalation models are no longer aligned with tenant realities, and that disconnect is where vacancy risk starts to build.”

Retail under pressure, offices hold ground‍

The data challenges global assumptions. Office space is showing resilience, with the highest satisfaction levels and strongest business confidence among tenants. Nearly 39% report a positive outlook,  positioning offices as a relative outperformer in a fragmented market.

Retail, however, tells a different story. Confidence remains fragile, with tenants squeezed between flat consumer demand and rising occupancy costs. A large proportion sit in a “neutral” zone, stable for now, but highly sensitive to any further cost increases.

‍

Marcus adds: “Retail is walking a tightrope. Margins are thin, and even small increases in occupancy costs can push tenants from stable to vulnerable very quickly.”

‍

Operational hurdles and the infrastructure gap‍

Beyond rent, the real pressure is operational. Electricity instability, municipal inefficiencies, and poor infrastructure account for a significant share of tenant frustration.

For industrial users, power reliability is mission-critical. For office and storage tenants, building maintenance and service delivery have become key decision drivers.

The implication is clear: landlords are increasingly being held accountable for failures they don’t fully control.

‍

Marcus notes: “Tenants don’t differentiate between municipal failure and landlord responsibility. If the building doesn’t perform, the landlord carries the consequence.”‍

The real risk: The ‘Neutral’ tenant‍

The biggest threat to income stability is not distressed tenants,  it’s the ones sitting on the fence.

Around 38% of tenants fall into a “neutral” category:

• Paying rent
• Remaining compliant
• But lacking loyalty or financial headroom

This group represents a ticking risk. At renewal, even modest escalations could push them out.

Uniform escalation strategies are no longer sustainable, they are actively increasing vacancy risk.

‍

Marcus warns: “The danger is underestimating the neutral tenant. They’re quiet, but they’re also the most likely to leave when the numbers stop making sense.”

‍

Growth constraints and the role of technology‍

The report highlights three primary growth barriers: 

• Weak economic conditions
• Rising utility costs
• Regulatory complexity

Interestingly, logistics and currency volatility rank lower, suggesting businesses have adapted. Technology, however, is emerging as a key unlock.

Two-thirds of tenants report improved efficiency from tech adoption, yet many have not fully leveraged tools that could optimise costs, manage utilities, or enhance operational control.

‍

Marcus adds: “Technology is no longer optional. It’s one of the few levers tenants and landlords can use right now to actively manage costs and improve sustainability.”

‍

From transaction to partnership‍

The traditional landlord-tenant model is under pressure. The report makes it clear: the future of commercial property lies in partnership, not transactions.

Tenants are demanding:

• Rental flexibility
• Transparent billing
• Reliable infrastructure
• Proactive engagement

Landlords who respond early, particularly to cost-sensitive tenants,  will protect income and occupancy. Those who don’t will face rising vacancies.

‍

Marcus concludes: “Managing tenant sentiment early is the difference between stable income and avoidable vacancy. If landlords don’t adapt, the vacancy numbers will eventually tell the story for them.”

‍

Shift has happened‍

This is not a warning, it’s a shift already underway. The commercial property sector is moving from predictable escalations to negotiated value.

In this new environment, success will depend on:

• Understanding tenant sentiment
• Leveraging technology
• Adapting pricing models
• Building real operational partnerships

Because going forward, income stability won’t be driven by leases, it will be driven by relationships.
