Local ordinance will always overrule Airbnb's rules no matter where you may live.
In Egypt it is illegal to host an unwed couple. Airbnb are more than happy to accept a reservation regardless of relationship status, and in fact, in their TOS they would consider a refusal to let to and unwed couple as hosting discrimination.
But local laws come first, just show that part of your local ordinance to Airbnb and they will cancel the reservation without fault to you.
It works both ways Inna, with almost any other form of activity, children are treated as a discount tariff. Many guests are annoyed that Airbnb regard children between the age of 2 and 12 as adults as far as reservation cost is concerned. In any case our arguments are valid, it costs the same to host a child as it does an adult but lots of guests don't see it that way, and we are fortunate that Airbnb do side with us on that one!
But Inna, the mechanism is there for you to abide by your cities ruling, and I would bet CX have had this issue crop up many times with Chicago hosts and Airbnb are well aware of how to handle it!
Hope you had a great Christmas and I really hope this new year will be a great one for you!
