Is it legal to rent out an unregistered vacation home in Paris, France?

In Paris, France, it is illegal to rent out an unregistered vacation home. The city requires all vacation rental property owners to register their properties with the local authorities before listing them for short-term rental. This regulation is part of a broader effort to manage the supply of tourist accommodations, preserve residential housing stock, and ensure compliance with local tax laws. Once registered, the property owner receives a registration number that must be displayed in all advertisements and listings for the rental property. Failure to comply with these registration requirements can result in substantial fines and penalties.

Trivia: Paris introduced these stricter regulations partly in response to the rapid growth of platforms like Airbnb, which dramatically increased the number of short-term rentals available, impacting the local housing market and community dynamics.
