Color-tagged structure
A color-tagged structure is a structure in the United States which has been classified by a color to represent the severity of damage or the overall condition of the building. The exact definition for each color may be different at local levels.
A "red-tagged" structure has been severely damaged to the degree that the structure is too dangerous to inhabit. Similarly, a structure is "yellow-tagged" if it has been moderately damaged to the degree that its habitability is limited (only during the day, for example). A "green-tagged" structure may mean the building is either undamaged or has suffered slight damage, although differences exist at local levels when to use a green tag.
