<P> 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 . </P>
