Nairobi Governor Johnson Sakaja’s administration is facing renewed scrutiny over construction safety and enforcement after a retaining wall collapsed at a construction site along Riverside Drive, killing four people and injuring 11 others.
The Saturday, November 14, 2026 incident occurred near Grand Residence as workers reported for their daily shifts.
The wall suddenly gave way, burying workers beneath the debris in an incident that has raised fresh questions about the safety of construction sites in the capital.
According to reports from the scene, 33 casual workers were in the immediate vicinity when the structure collapsed.
Rescue teams, emergency responders and local authorities rushed to the site to search for survivors and assist those trapped beneath the rubble.
Initial headcounts established that 22 workers had been accounted for, while the 11 injured were rushed to different hospitals across Nairobi for treatment.
Police cordoned off the area as rescue operations continued, with authorities expected to establish the circumstances surrounding the collapse.
Sakaja faces questions over construction oversight
The tragedy places renewed attention on the Nairobi County Government’s responsibility for development control, construction approvals and enforcement of building safety regulations.
As governor, Sakaja heads the county administration responsible for key urban planning and development control functions, putting his administration’s enforcement record under scrutiny.
Investigations will be crucial in determining whether the construction site complied with approved plans, safety requirements and other regulatory standards.
The incident comes barely a day after another building collapsed along Mombasa Road, killing six people.
The two incidents have intensified concerns over construction safety in Nairobi, with questions emerging over whether existing inspection and enforcement mechanisms are sufficient to prevent building-related disasters.
Authorities are yet to establish the cause of the Riverside Drive collapse or determine whether any regulatory failures contributed to the tragedy.
