Sadly, I think you're right.
Paranormal stories in a single location work well for a movie or mini-series, but eventually, you run out of room to grow. Paranormal series need to be "road" stories where you have encounters in new locations to keep it interesting. Plus, you need a new bad guy now and then to mix it up.
That's the issue that shows like Supernatural have had from time to time: getting stuck on one bad guy (the Yellow-Eyed Demon, The Devil, Leviathans, etc.). It's one thing to have an overall arc, but a far different thing when the arc is the only story.
In a one-setting story (in this case, the apartment building), it becomes impossible to provide good scares without the viewer wondering a) why more people haven't seen the creepy stuff and b) why there aren't more urban legends about that stuff publicly. In this day and age, a haunted apartment building run by the devil (or whatever O-Quinn's character is), would have a lot of internet buzz.
