But if Airbnb was serious about sustainability and respecting local law they would either ban whole house listings or request proof of said permit in Berlin. Even if they were motivated to do this, it would simply wipe out a very large percentage of rooms available which would make zero business sense for airbnb. This is again more evidence of the lack of sustainability of their business model in the current form factor.
