Don't you think there should be something like that?
Let's take a look at sports, for example in UFC there are sports commissions in each state, and they are doing drug tests, as well as health checks to make sure that those whose injuries ain't healed yet ain't available to fight.
Now in football (or soccer for some of you) there are rules made by UEFA known as Financial Fair Play, or in USA in MLS they have salary cap.
There are also multiple other rules like those who are U-18 for example 16-year-old players which move to foreign country they need to live in home with kind of 'foster parents, or in a dorm with other young players, but there is security, coaches, teachers etc.
Whole world have some kind of rules, for example you can't built skyscrapers near some castle because city council/regional government bans 'tall' buildings in in this area.
So shouldn't there be some organization that will prepare guidelines for idols dorm/housing? Like m2, a number of sleeping rooms, bathrooms, the quality of the interior, if it ain't good then must have renovations, etc.
