Nairobi building collapse raises safety concerns as rescuers search rubble

An unfinished high-rise in Eastleigh, Nairobi, suddenly collapsed during construction on Friday. It was reportedly about 18 storeys tall, leaving people feared trapped beneath the rubble. Reaching them was difficult because the site was tightly squeezed between surrounding high-rise buildings. Rescue teams struggled to access the wreckage.

Police rescued one woman and heard another person calling from underneath. Engineers said cracks and other signs of distress had reportedly appeared before the collapse. Nairobi’s governor said the building lacked an occupation certificate, confirming it was not approved as safe for use. Missing approvals and weak oversight may have increased the danger.

The collapse highlights wider construction safety problems in Nairobi’s rapid building boom. A national inspection found 87 percent of audited buildings failed standards or lacked required approvals. Nairobi recorded 86 collapses between 2009 and 2019, killing about 200 people. Effective inspections, professional supervision, and clear emergency access are vital as construction continues.

An occupation certificate is the authorities’ formal confirmation that a building is safe and legally fit for people to occupy. Without it, officials have not approved the building for use, so its safety and compliance remain uncertain.

In Nairobi, Governor Johnson Sakaja said the collapsed building had no occupation certificate. That did not prove the missing certificate caused the collapse, but it showed the building lacked required formal sign-off. Without that approval, authorities cannot confirm that construction met legal and safety requirements before occupation.

Kenya’s National Building Inspectorate found 87 percent of audited buildings nationwide failed standards or lacked required approvals last year. In the reported collapse, engineers said cracks had reportedly been observed, and the roughly 18-storey structure fell during construction. The certificate system helps prevent potentially unsafe buildings from being occupied. Its absence should prompt checks before anyone enters, especially where poor materials or unverified work may create serious risks.

Unsafe or unauthorized construction is widespread in Kenya, not an isolated problem. The National Building Inspectorate found 87 percent of buildings audited nationwide last year failed standards or lacked required approvals. That matters because weak oversight can leave people living or working in dangerous structures.

The collapsed Eastleigh building shows how failures can become deadly. Nairobi’s governor said it had no occupation certificate, meaning officials had not formally approved it as safe to occupy. Engineers also reported earlier cracks, while wrong materials, unqualified supervision, and corner-cutting were cited as risks.

Nairobi recorded 86 building collapses between 2009 and 2019, causing an estimated 200 deaths. Recent examples include five deaths in a six-storey collapse in September 2022 and 49 deaths in April 2016. With annual construction rising from 20,025 buildings in 2022 to 25,090 last year, stronger inspections and enforcement are urgent.

Unsuitable materials, ignored cracks, and skipped approvals can weaken a building until it suddenly collapses. These shortcuts can trap or kill people, while making rescue harder in crowded areas.

In Nairobi’s Eastleigh, a building thought to be about 18 storeys collapsed during construction on Friday. Engineer John Ogallo said people had noticed cracks, while another engineer warned that wrong materials can turn a building into “a time bomb.”

The collapse reduced the structure to rubble, and rescuers initially struggled between nearby high-rises. Nairobi’s governor said it had no occupation certificate, and Kenya’s inspectorate found 87 percent of audited buildings failed standards or lacked approvals last year. Nairobi recorded 86 collapses from 2009 to 2019, causing an estimated 200 deaths. With construction rising from 20,025 completed buildings in 2022 to 25,090 last year, stronger inspections and professional oversight are essential.

Responsibility is shared. Contractors and engineers must use qualified professionals to check designs, materials, and construction. Government inspectors then audit sites and issue an occupation certificate only when a building is safe and legally fit to use.

At the Eastleigh collapse, Nairobi Governor Johnson Sakaja said the building had no occupation certificate. Engineers also reported warnings, including cracks, but construction continued. This shows how missed inspections, poor materials, or bypassed approvals can leave dangerous work in place.

Kenya’s National Building Inspectorate found 87 percent of audited buildings failed standards or lacked approvals. That puts pressure on inspectors, county authorities, contractors, and engineers to enforce rules before occupancy. Nairobi completed 25,090 buildings last year, up from 20,025 in 2022. That growth makes independent checks and accountability increasingly important.

Nairobi’s population growth is driving a rapid building boom, especially as people arrive from rural areas and neighboring countries. More projects and taller buildings increase the workload for inspectors, engineers, and approval systems. When oversight cannot keep pace, unsafe work can slip through.

In Eastleigh, an unfinished building thought to be 18 storeys collapsed during construction. Officials said it lacked an occupation certificate. Engineers reported earlier cracks and warned that poor materials can become “a time bomb.” These failures show how bypassed approvals, weak supervision, and rushed construction can turn growth into deadly risk.

The pressure is visible in the numbers: Nairobi completed 25,090 buildings last year, up from 20,025 in 2022. Yet 87 percent of audited buildings nationwide failed standards or lacked required approvals. Unless enforcement, professional supervision, and safe materials expand with construction, more residents and workers could face preventable collapses.

A multi-storey building stays upright when every weight has a safe path into the ground. Columns, beams, walls, foundations, and strong connections share loads, while suitable materials resist bending, cracking, fire, and weather. Building codes require engineers to calculate these forces, approve designs, inspect construction, and confirm safety before occupation.

In Nairobi’s Eastleigh, a building thought to be 18 storeys collapsed during construction. Engineers reported possible cracks. Authorities said it lacked an occupation certificate. Weak materials or supports can break the load path and trigger progressive collapse. The article does not identify the exact failure, so investigators must determine it.

Kenya’s National Building Inspectorate found 87% of audited buildings failed standards or lacked approvals. Nairobi recorded 86 collapses from 2009 to 2019, with an estimated 200 deaths. Effective enforcement, competent professionals, quality materials, inspections, and honest approvals are essential as construction accelerates.
