Commercial Vacancy Rates in Gauteng 2026: What Landlords Need to Know

Gauteng's commercial property vacancy rate stabilised at approximately 11.4% in Q1 2026, with Grade A offices in Sandton and Rosebank seeing renewed absorption from financial services and technology tenants. Secondary nodes — particularly parts of Midrand and older Johannesburg CBD stock — continue to face headwinds from decentralisation trends.

For landlords, the headline number masks significant divergence. A well-maintained industrial asset in Germiston or Boksburg is currently experiencing near-zero vacancy, while a B-grade office park in a peripheral node may be sitting at 25–30%. The asset, its location, and its management quality are determining outcomes far more than macro trends.

What this means for your mandate: Proactive lease management — engaging tenants 12 months before expiry — is no longer optional. At Stone Capital, all managed properties trigger automatic renewal outreach at the 12-month mark, with parallel marketing initiated if renewal probability falls below 70%. This approach has consistently reduced our portfolio-wide average vacancy downtime by over 30% versus the market average.
