It is sometimes used for places and people but now that you mention it I can only really think of examples of it being used for slightly negative references. I would say there’s usually some contempt behind it. Place: “I have to go to that DMV jawn and renew my license.” People: “Them TSA jawn opened my bag.” Person: “She’s my ex jawn.” It can also be used to refer to women or a woman in a belittling way. Somewhat similar to “bitch.” For example: “That jawn is clingy.” or “Them jawns be crazy.”
