Natural disasters cause an estimated $228 billion in annual damage to residential buildings worldwide, according to findings highlighted by the United Nations Office for Disaster Risk Reduction (UNDRR) on the International Day for Disaster Risk Reduction. The assessment places housing at the centre of efforts to reduce the human and financial consequences of floods, earthquakes, cyclones and tsunamis.
The Global Infrastructure Risk Model and Resilience Index estimates annual losses of about $426 billion across the global building stock under current climate conditions, with residential properties accounting for approximately 53 percent. These are modelled annual losses, not damage recorded during a single calendar year.
UNDRR also drew attention to the importance of household emergency planning. In findings from the Lloyd's Register Foundation World Risk Poll 2026, 83 percent of people with both an emergency plan and confidence in their ability to respond took protective action after receiving a warning, compared with 27 percent among those lacking both.
The agency called for safer building standards, risk-informed land-use planning, early warning systems and more accessible financing for disaster resilience. Housing reconstruction, it stressed, should reduce future risk rather than simply replace what was destroyed.
