Quoted from SilverUnicorn:
Just make sure your city or town doesn't think you're running a business with an outside sign.
I love the idea, not trying to be a debbie downer, just that I know how weird my township can be about stuff. Also might not want to advertise what you have in the building. Just a thought.
It's for an actual arcade inside a drive in movie theater complex, so I think I will be ok.
