Eastleigh Building Collapse: Multi-Storey Building Under Construction Falls on 9th Street With Several Feared TrappedEastleigh Building Collapse: Multi-Storey Building Under Construction Falls on 9th Street With Several Feared Trapped

The collapse in one of Nairobi's busiest commercial districts puts fresh scrutiny on building safety and construction oversight in Kenya's property sector. No official count of the dead, injured or missing had been published when this report was filed, and the cause is unknown.

What is known so far

The structure came down at about 1pm, according to initial reports, while the Kenya Red Cross later said the collapse happened at around 1.40pm. The difference in timing has not been explained, and Mwenendo is treating both as unconfirmed until the emergency services give an official time.

Nairobi police commander Issa Mohamed said more officers had been sent to coordinate emergency service providers, and that the authorities had not yet received full information on the incident. The Kenya Red Cross dispatched a team to assess the situation.

The height of the building is also disputed. Several reports describe an 18-storey building under construction, but Mohamed said the structure was about 10 floors. Mwenendo has not been able to verify the number of storeys independently.

Pictures from the scene show slabs of concrete stacked in layers as rescuers and onlookers gather at the foot of the debris. The area is usually busy at that hour, which raises concern for pedestrians and traders as well as for workers who may have been on the site.

Unverified claims

Social media posts have circulated far higher casualty figures and reports of looting at the site. Mwenendo has not verified any of these claims and has not repeated the figures. Readers should treat numbers that do not come from the police, the Kenya Red Cross or the county government with caution.

The owner of the building, the contractor and the status of its permits have not been made public. Regulation of the industry sits with bodies such as the National Construction Authority, and it is not yet clear whether any inspection of the site had taken place.

Why it matters for business

Construction is one of the larger drivers of Kenya's economy, and a collapse of this scale can affect developers, lenders, insurers and the traders who operate around the site. As Mwenendo earlier reported, construction growth eased to 6.0% in the second quarter of 2026 from 7.3% a year earlier.

Mwenendo earlier reported on how excise changes on building materials were meant to lower construction costs, and the sector is also expected to benefit from public works such as the Nandi road programme. A confirmed structural failure would be likely to bring tougher checks on sites across the capital.

Mwenendo will update this story when the authorities confirm the casualty figures, the height of the building and the cause of the collapse.
