Lagos State, Nigeria’s economic hub, is facing a persistent building safety crisis. In the megacity, home to an estimated 20 million people, skyscrapers rise alongside sprawling informal settlements, while building collapses continue to claim lives with alarming regularity.
The rapid pace of construction, coupled with alleged negligence and weak enforcement, has turned parts of the city’s building boom into a recurring source of tragedy.
Building collapses in Lagos have become emblematic of a wider crisis involving alleged negligence, regulatory failures and impunity. Structures meant to provide homes, businesses and livelihoods have repeatedly collapsed, trapping and killing residents, workers and passers-by, while questions over accountability often remain unresolved.
From 2017 to mid-2026, families have mourned loved ones who were killed in building collapses across the state, while allegations of professional negligence, regulatory lapses and non-compliance with building standards have continued to surface.
Data compiled from multiple sources, including official reports, academic studies and statements by government agencies, points to a persistent pattern of building collapses in Lagos over the past decade.
