ATLBlaxican, that's a good question, and I'm sure that someone will post a definitive answer, but my guess is that while it's probably possible to "register" or "trademark" a building name, few probably do. I know for example that there are shopping centers and malls all across the country that share the same name, and, when you think about it, you can even have businesses with the same name in different states, so, I think there's not an issue with two buildings is different states having the same name.
