Shelter Damage Level
https://schema.aidops.org/vocab/shelter-damage-level
Severity of physical damage to a dwelling observed in a post-shock assessment. The five-tier scale below follows IOM Displacement Tracking Matrix (DTM) labels and aligns with Sphere Handbook 2018 Chapter 4 damage categories. The Shelter Cluster's four-tier assessment (heavily / moderately / slightly damaged / no damage) maps onto this scale with the destroyed tier folded into heavily damaged; system_mappings records that crosswalk.

IOM Displacement Tracking Matrix (DTM) Shelter Damage Assessment (https://dtm.iom.int/)
IOM DTM's post-disaster damage labels are the most widely reused operational taxonomy for this measurement; the Global Shelter Cluster's four-tier version is the second-most common. Neither is a legal or engineering classification, and neither claims to be. Sphere 2018 Chapter 4 frames the operational use of these tiers for recovery programming.
Values
| Code | Label | Standard code | Definition |
|---|---|---|---|
destroyed | Destroyed | The structure is completely destroyed or collapsed; rebuilding from foundation is required. Not habitable under any condition. | |
severely_damaged | Severely damaged | Major structural damage to load-bearing elements (walls, roof, foundation) rendering the dwelling unsafe. Extensive reconstruction is required before safe occupancy. | |
moderately_damaged | Moderately damaged | Significant damage to non-structural elements (walls, openings, partitions) or limited structural damage. Major repairs are required; dwelling may be temporarily uninhabitable. | |
minor_damage | Minor damage | Minor cosmetic or surface damage (cracks, finishes, fixtures). Dwelling remains habitable; minor household-level repairs are sufficient. | |
undamaged | Undamaged | No observable damage from the shock. Recorded to distinguish from missing observation. |
