Johannesburger investors eye office build as mayoral race and power maintenance reshape market
A "future-forward" office precinct has pulled Canadian capital back into Johannesburg, and planned power maintenance across February and March has sharpened the trade-offs for johannesburger investors on timing and asset selection. The interplay of the mayoral race, municipal services and the 2026 national budget now figures directly into demand, rents and CAD returns.
Future-forward office project draws developers and tenants
This week a future-forward office project in Johannesburg drew attention from developers and tenants, signalling fresh commercial capex and a shift in sentiment. The plan emphasises green design, flexible floorplates and tech-ready spaces — the themes occupiers want — and, for Canadian investors, is a sign that new supply can again be financeable in prime nodes.
Mayoral race between Helen Zille and Herman Mashaba shifts underwriting for Johannesburger investors
The Joburg mayoral race between Helen Zille and Herman Mashaba, paired with South Africa budget 2026, will shape demand, rents and valuations in the Johannesburg office market. Governance, services and infrastructure are now core to underwriting; portfolio risk will depend on how quickly service backlogs are cleared and permits flow. For johannesburger investors translating returns to CAD, timing and quality selection matter.
Permitting speed, visible policing and by-law enforcement influence where leases land. If the next administration restores confidence in inner-city blocks, brownfield conversions and A-grade refurbishments can scale; if not, capital continues to favour Sandton and Rosebank. Stronger delivery can lift Grade-A take-up and lower incentives, while weak delivery can widen vacancies and pressure net effective rents.
City Power warns of packed maintenance schedule across suburbs and CBD
City Power has warned residents to brace for a wave of planned power interruptions across February and March as the utility rolls out maintenance at multiple substations. The utility said the outages form part of routine repairs but warned restoration could be delayed if weather conditions interfere with the work, and described the electricity system as "constrained, " urging residents to reduce consumption to prevent further strain and unplanned blackouts.
Specific interruptions listed include: Alexandra on Wednesday, 25 February from 9: 00 to 17: 00 affecting West Bank, Far East Bank extensions 9 and 10 and parts of Lombardy East; Lunar Substation on Thursday, 26 February from 9: 00 to 17: 00 affecting Univille, Lawley, Finetown, Mountain View, Ennerdale Ext. 8 and Lenasia South; and maintenance at Siermert Substation on Sunday, 1 March affecting Berea, Troyeville, Jeppestown, Fairview, Highlands, Doornfontein, New Doornfontein and the Johannesburg CBD.
Mondeor Substation outage set for March 8 and customer guidance

Customers seeking clarity can contact the City Power call centre on 011 490 7484 or the toll-free number 0800 202 925.
Asset renewal backlog and ageing equipment heighten long-term risk
The City of Johannesburg’s Infrastructure Plan 1. 0 (2024/25) sets the context for these interruptions: City Power is facing a R44. 25-billion asset renewal backlog. The report confirms that ageing and deteriorating infrastructure contribute to frequent and worsening outages and flags serious public health and safety risks linked to failing assets.
City Power emphasised that large portions of the core electricity network — underground cables, substations and transformers — are between 60 and nearly 100 years old. Across 269 substations much equipment has exceeded its intended lifespan. Of 216 power transformers, about 20% are classified as high risk due to age and insulation deterioration, while about 10% of 717 feeder boards require replacement.
City Power spokesperson Isaac Mangena said technical teams respond continuously to faults logged by residents and noted, "It is worth noting that there are currently no widespread outages on a daily basis, but our technical teams respond to outages as and when they are logged by customers. " Mangena added that ongoing outages are caused by a combination of ageing infrastructure, network overloading, vandalism, cable theft and illegal electricity connections, and that repeated interruptions in the same areas are often linked to sustained pressure on infrastructure caused by high demand and dense illegal connections.
What investors are being told to do
The market guidance for Canadian capital is operational and financial: factor municipal delivery, service uptime and permitting into asset selection; stress test cash flows for 300 to 500 basis points of currency and rate shocks; decide early on hedging; and target low-vacancy assets. Fiscal choices at national level and the path set by South Africa budget 2026 will influence operating costs, tenant health and financing spreads, while South African borrowing costs and rand swings will shape entry prices and exit IRRs when translated to CAD.
Access routes into Johannesburg real estate noted in market commentary include global brokers with South African listings, diversified emerging-market or frontier funds with a South Africa sleeve, or private partnerships focused on core nodes — but investors are reminded to check mandate limits, liquidity and fees before committing capital.
