A building collapsed in Nairobi's Eastleigh district on Friday, October 23, 2026, trapping several people and prompting a multi-agency investigation. Interior Cabinet Secretary Kipchumba Murkomen announced the probe, involving the Directorate of Criminal Investigations, Nairobi County government inspectors, the National Construction Authority, and the relevant ministry. Rescue teams continue searching for seven people reported missing.

The National Construction Authority named the developer, contractor, and engineers involved. The developer was 9th Street Plaza Limited, and the contractor was Stromax Holdings E.A. Limited. Emmanuel Mwangi Maina was listed as the structural engineer. The building, located along 8th Street, collapsed during Friday prayers, according to a report by Geoffrey Mosiria, a former Nairobi County Chief Officer.

Officials confirmed the building lacked an occupation certificate but had a ground floor in use. The incident occurred in a densely populated area, leading to chaos as crowds gathered and roads were blocked. Emergency agencies were called upon to deploy rescue personnel, ambulances, and structural engineers.

This collapse follows a pattern of construction-related incidents in Eastleigh, where regulatory oversight has been questioned. The area has seen previous building failures, raising concerns about safety standards and enforcement. The current probe aims to determine accountability and improve oversight.

The collapse highlights ongoing challenges in Nairobi's construction sector, where rapid development sometimes outpaces regulatory compliance. The incident has sparked calls for stricter enforcement of building codes and greater transparency in construction projects.
