Paris is coming for your Airbnb. And the rest of Europe is watching.

The city's deputy mayor for housing has put a number on it — 20,000 apartments he wants reclaimed from the short-term rental market. Investigators are already knocking on doors. Literally.The message from City Hall? "We want to show that from now on, it is not a great investment."That's not a warning. That's a policy statement.And from 20 May, it gets harder to hide. The EU's new data-sharing regulation means Airbnb, Booking.com and every major platform will be required to hand host data directly to authorities — giving cities the enforcement infrastructure they've always lacked.Spain fined Airbnb €64 million last year. Italy changed the tax rules. Germany's courts just made subletting for profit grounds for eviction.Airbnb's counter-argument — that restrictions haven't actually helped renters, just filled hotel beds — has merit. In Amsterdam, a 50% drop in STR stays still saw tourist numbers climb 12%. Hotels won. Locals didn't.But that argument isn't slowing the regulatory wave.The operators who will survive this aren't the ones fighting the regulation. They're the ones who've already built compliance into their model.The question isn't whether the rules are changing. It's whether your business is ready.
