Finding the courtroom in which your proceeding is located is simple.
You may already have a "Notice of Hearing" with a courtroom listed. If not, there are Display Boards located on every floor of the courthouse that show courtroom information.
When entering the south public entrance, after going through security, you will notice a set of displays across from the elevators. Some of these displays show the courtroom where a specific docket is located. Other displays show hearings and their respective courtrooms sorted by party name. If you are a party to the case, just wait for your name to appear and the courtroom will be listed. Otherwise, wait for the case number to appear.
The courtroom number corresponds to the floor where the courtroom is located. For instance courtroom "3A" will be located on the third floor.
Take the elevators or stairs to your floor. Each courtroom has a clearly displayed sign with the courtroom number on it.
