As I understand it and I'm not a lawyer but I do work in housing finance, housing, rentals, and short term rental all fall under the fair housing act. This is purposefully broad and done so because of how discrimination is such an affront to human rights. That being said Airbnb is merely hoping to avoid any class action litigation, which will likely come as a result of tenants viewing the broker as not putting a good faith effort to preventing discrimination. The broker, after all, cannot intentionally facilitate illegal behavior to make a profit, that would just create puppet mafias. They probably have figured they are less likely to be found guilty of facilitating the illegal behavior of fire code violations because fires are just a lot less likely and a lot less externally obvious to the broker. TLDR: The laws are laws whether Airbnb says they care about them or not, but should Airbnb put forth a good faith effort to prevent flagrant lawbreaking on their website they'll likely avoid being seen as legally culpable.
