It's assumed because of several factors:

1. Roan's Greater Washington and Baltimore Rail Transit map.

2. Baltimore has a massive towering BOA building. Even though the building looks nothing like the tower, it's a historic well-known landmark (https://en.wikipedia.org/wiki/Bank_of_America_Building_(Baltimore). It's easy to imagine that it was rebooted in the series to look more like modern BOA building designs with some art deco and gothic elements.

3. The guess for BOA comes from the section of lettering near the fighting area that is above the columns of an old building. Similar columns are located at a structure below the real BOA building in Baltimore. You can actually see those columns slightly on the Wikipedia page linked above. The only difference is that there isn't a triangular top above the columns as in the series, BUT...that again could have been artistic license.

4. The swing doors leading into the throne room are the type that you would usually see in a  corporate building -- usually leading to a conference room. Some museums, government buildings, hospitals and restaurants/commercial kitchens also have those doors. With the other elements, a bank corporate office building makes more sense.
