What does this mean? Being the person owning the place and offering someone to stay in it, or being the one staying in it?
The speaker is probably a businessman trying to find a place for his business. He's asking the building owner about the possibility of renting the building.
Yes, this is the way it comes across to me. That someone is looking to rent the building, and inquiring the owner of the building if it is available for rent.
...i agree with @Femmy813541 and @4nthonylol: it's somebody asking if the building is for rent - it's literally saying to the owner: "are you renting this place out?" or "is this place for rent?" ...cheers!
