I haven’t done it, but I had an idea to build a multi-floor commercial lot and have each floor be for exclusive use by a different club using the door locks feature. For example, you could have a criminal club meet in the basement, a Juicers Anonymous meet on another floor, etc., and each floor could be furnished specifically for that club.
You could even have the first floor be an actual business, like a restaurant or retail store, and then all the other floors would be private access.
