The three colored tags on the map (green circle, red diamond, and yellow square) match placards posted on inspected structures. Each type of placard is used by inspectors under the following circumstances:
Green (Inspected)* - Buildings can be damaged, yet remain safe – the safety of the building was not significantly changed by the disaster.
Red (Unsafe) - Buildings are damaged and pose an imminent threat to life or safety under expected loads or other unsafe conditions.
Yellow (Restricted Use)* - There is some risk from damage in all or part of the building, but the full extent of damage may be uncertain or cannot be ascertained within the time and resources available to a Rapid Evaluation team. Buildings with yellow tags have limited use, with case-by-case restrictions. For example, certain portions of a home may not be habitable until a permit has been issued and repairs are made.
*Important Note: Although a building may be placarded “Inspected” or “Restricted Use”, specific areas in and around the building could be further identified as unsafe.
