WASHINGTON, Ill. -- Georgetown Commons residents need a police or firefighter escort to get into their building, and some of them they cannot enter.
Those marked with a red placard were deemed unsafe by OSHA safety standards.
The yellowing markings mean the structure is somewhat inhabitable, it is a case by case basis.
And the green placard indicates it is safe to go in.
Each resident is also allowed only 30 minutes in their residence at a time.
