This covers any types of short-term (less than 90 days at a time) rentals to tourists - that would include renting out on Airbnb or similar online platforms, renting as a gite or rentals organised through other means. Any property listed as a maison secondaire (second home) that is rented out to tourists, even just for a couple of weeks of the year, now needs to be registered with local authorities as a meuble de tourisme.
