Short-term rentals, locally termed "meublé de tourisme," are legal in Paris, but they are heavily regulated to curb illegal subletting and protect housing availability. Only primary residences can be rented out for short-term stays, with a maximum limit of 120 days per year for rentals, requiring owners to register with the Paris City Hall to obtain a unique registration number. This registration helps the city monitor compliance and resolve issues with unregistered properties, contributing to the broader urban housing market. The short-term rental market is primarily fueled by tourism, drawing both leisure travelers and business visitors, making urban apartments particularly popular, especially in central areas that are close to attractions. The City of Paris manages these regulations through its housing department, ensuring adherence to local laws. For more information, you can refer to Paris City Hall.
