I believe the “rules” actually allow you to rent a home you own here, but there are certain restrictions regarding it. I even think the developers own a business here that you can contract with to manage your rental(s). However, renting a room out of your home may be a different issue and might be considered running a business out of your home. The same would be true, IMO, of operating a pet boarding service (one you are getting paid for). Contact Community Standards and report it. The developers enforce rules like that on a complaint driven basis. There really isn’t any other way to do it.
