Gaza’s damaged buildings are not simply a housing shortage—they are an ongoing structural-safety hazard. As of June 16, 2026, UN satellite analysis estimated that 201,290 structures, or about 82% of all structures in the Gaza Strip, had sustained damage. Of those, 134,422 were classified as destroyed, 13,848 as severely damaged, 28,096 as moderately damaged and 24,924 as possibly damaged.
The danger persists because a building can remain standing while its structural capacity has been seriously compromised. Cracked or displaced load-bearing elements, weakened connections, damaged foundations, unstable floors and partially collapsed walls can leave structures vulnerable to further collapse. In Gaza, that engineering risk is compounded by enormous quantities of rubble, unexploded ordnance, limited access to specialist assessment and the fact that some displaced families have few alternatives to damaged buildings. On September 16, 2026, the UN humanitarian coordinator reported that a building collapsed in Gaza while an estimated 100 people, including 50 children, were inside, and said hundreds of damaged structures across Gaza had been assessed as unsafe.
Why a standing building can still be structurally unsafe
A building does not have to collapse immediately to become dangerous.
Modern buildings rely on interconnected structural elements—columns, beams, load-bearing walls, slabs, foundations and their connections—to transfer weight safely to the ground. Severe impact can damage one or several of these components without causing an immediate total collapse.
For example, a damaged column may still carry some load but have substantially less capacity than before. A cracked concrete slab may remain apparently stable while its reinforcement has been damaged. Walls can lose their ability to resist lateral forces, while weakened connections between structural components can make a building more vulnerable to movement or additional loading.
This is why visual appearance alone is not enough to determine whether a damaged building is safe to occupy. A structure that appears intact from outside can require detailed engineering inspection before people can safely return.
Gaza’s damage is not one uniform category
The UN Satellite Centre, or UNOSAT, uses satellite imagery to distinguish different levels of visible structural damage. Its June 2026 assessment classified affected structures into destroyed, severely damaged, moderately damaged and possibly damaged categories.
Those categories are useful for understanding the scale of the crisis, but they should not be treated as a substitute for an individual building inspection.
| Damage category or assessment | Latest reported figure | What it means for safety |
|---|---|---|
| Destroyed structures | 134,422 | Structures assessed as destroyed; generally unsuitable for occupancy |
| Severely damaged structures | 13,848 | Major damage; detailed assessment is required before any decision about use |
| Moderately damaged structures | 28,096 | Significant damage that can require repair and engineering evaluation |
| Possibly damaged structures | 24,924 | Satellite evidence suggests damage, but further verification is needed |
| All affected structures | 201,290 | About 82% of Gaza’s structures as of June 16, 2026 |
| Housing units damaged | 328,627 | Residential damage remains a major component of the shelter crisis |

The distinction is particularly important because “damaged” does not automatically mean “about to collapse,” just as “standing” does not mean “safe.”
The hidden danger is often inside the structure
The most consequential damage may not be visible from the street.
A structural assessment can need to establish whether columns, beams, slabs, foundations and connections remain capable of carrying expected loads. Engineers may also need to determine whether damage has propagated beyond what can be seen on the surface.
Fire and prolonged exposure can create additional complications. Water entering damaged buildings can accelerate deterioration of some materials and corrode exposed steel reinforcement. Repeated movement, weather and additional impacts can further change a structure that was already weakened.
In Gaza, however, the question is not only whether a building can withstand normal occupancy. Humanitarian agencies are also dealing with structures that have been damaged in an active conflict environment, sometimes near areas where military activity continues.
OCHA has repeatedly reported families sheltering in damaged buildings because safer accommodation is unavailable. In July, it specifically reported that some school buildings being used as shelters had structural damage from previous military operations and raised concerns about potential collapse.
The inspection gap is itself a safety problem
One of the biggest difficulties is knowing which buildings can safely be repaired and which cannot.
By July 2026, Shelter Cluster partners had inspected 33,469 of an estimated 227,703 buildings requiring assessment—about 15% of the estimated total. Those inspected buildings represented approximately 159,000 housing units. Among the assessed housing units, 95,290, or 60%, were classified as destroyed or having severe structural damage, while 63,711 had minor to moderate damage.
That assessment is different from the satellite-based UNOSAT inventory. It is based on detailed inspections of a subset of residential buildings, which means its percentages should not be extrapolated mechanically to every building in Gaza.
The contrast nevertheless illustrates the practical problem: the existence of a damaged building is easier to establish than determining exactly what can safely be done with it.
Detailed assessments require access, trained personnel, equipment and sufficient security to inspect structures. In a setting where displacement and insecurity remain widespread, completing a building-by-building assessment is exceptionally difficult.
Rubble creates a second layer of risk
Structural instability is only one part of the danger.
Gaza has accumulated tens of millions of tonnes of debris. OCHA reported in July 2026 that approximately 630,000 tonnes had been cleared from roads and essential-service facilities, but that this represented only a fraction of the more than 60 million tonnes generated since October 2023.
Rubble can conceal unstable sections of buildings, obstruct access for emergency responders and make it harder to inspect foundations or lower floors.
It can also contain hazardous materials and unexploded ordnance. By August 2026, OCHA reported that humanitarian partners had conducted 3,199 assessment missions since October 2023 to identify and mark explosive hazards, while still lacking authorization to move or safely dispose of those hazards.
That means debris clearance cannot simply be treated as a conventional demolition or construction exercise.
Why damaged homes remain occupied
The structural-safety problem exists alongside a shelter shortage.
Families may continue living in damaged structures because tents or other temporary accommodation provide limited protection, because alternative shelter is unavailable, or because moving would mean another displacement.
This creates a difficult risk calculation for families: a damaged building can be dangerous, but leaving it can also expose people to other hazards associated with inadequate shelter, overcrowding, weather and lack of services.
OCHA reported in May that many displaced families were still sheltering in severely damaged structures because safer alternatives were unavailable.
The situation is particularly serious as damaged buildings are also used for collective shelter. A building designed to accommodate one population under normal conditions can face additional stresses when large numbers of displaced people are living inside it.
Repairable does not necessarily mean immediately habitable
One of the most important distinctions in Gaza’s structural crisis is between repairability and habitability.
A building may ultimately be repairable but still be unsafe to occupy until temporary stabilization or substantial structural work is completed. Conversely, a building with relatively limited visible damage may require inspection before residents return if important structural components have been affected.
OCHA’s April reporting illustrates this distinction. Among more than 91,000 housing units assessed by April 5, approximately 40,000 were classified as totally damaged and nearly 51,000 as partially damaged. Of the partially damaged units, 9,075 were considered uninhabitable, while 40,095 were considered habitable.
Those findings show why simply counting “damaged homes” does not tell the whole story. The crucial questions are how severe the damage is, whether the structure remains stable, whether essential services work, and what repairs are required before occupation.
Weather can turn structural weakness into a larger emergency
Buildings that have survived initial damage can face additional stress from exposure.
Rain can enter through damaged roofs and walls, while standing water can affect already compromised structures and surrounding ground conditions. Poor drainage and damaged water and sanitation networks can compound the problem.
This is particularly relevant for displaced families living in damaged buildings or makeshift shelters. OCHA has reported that overcrowding, damaged infrastructure and inadequate shelter continue to undermine safe living conditions across Gaza.
The risk therefore changes with the season and with each additional deterioration of the structure. A building that was marginally usable at one point cannot automatically be assumed to remain so.
What has to happen before large-scale rebuilding
The structural crisis cannot be solved simply by bringing in construction materials.
A safe recovery process requires several stages: identifying hazardous structures, assessing which buildings can be stabilized or repaired, managing unexploded ordnance and hazardous debris, clearing rubble safely, documenting damage and then determining what can be rebuilt.
The April 2026 Rapid Damage and Needs Assessment by the World Bank, United Nations and European Union was designed as a technical basis for recovery planning. It combines remote sensing with ground-verified information but explicitly says that additional on-the-ground sectoral assessments are needed to inform detailed recovery planning.
That distinction matters. A satellite map can show where a roof has disappeared or where a building footprint has changed. It cannot, by itself, certify that a particular column, foundation or connection is safe.
The immediate question is not how many buildings are standing
The most important unresolved issue is how quickly unsafe structures can be identified and made safe while people remain displaced.
The September 16 collapse demonstrates why the distinction between damaged, repairable and safe to occupy is critical. The UN humanitarian coordinator said the building that collapsed was occupied by an estimated 100 people, including 50 children, and warned that hundreds of other damaged structures assessed as unsafe remain occupied because people lack better alternatives.
Gaza’s structural crisis will therefore not be measured only by how many buildings have been destroyed. A more consequential measure for the people living there is how many damaged structures have been professionally assessed, how many can be safely stabilized or repaired, how many must be demolished, and how quickly residents can move from unsafe buildings into genuinely secure shelter. Until those questions are answered at scale, a building that is still standing cannot automatically be treated as a building that is safe.
