Montmartre 18th Arrondissement Short-Term Rental Registration Rule Alters Housing Availability for Local Tenants

The 18th arrondissement council approved a mandatory registration system for short-term rental platforms on 2 July 2026, requiring all hosts to obtain a city-issued number before listing properties in Montmartre. The rule applies to every apartment and house within the Butte Montmartre perimeter and covers platforms such as Airbnb and Booking.com. Residents who rent out rooms or entire units for fewer than 90 days a year must now comply or face fines starting at 5,000 euros.

Background on the registration requirement

The measure follows the Paris municipal council’s 2025 decision to tighten enforcement of the national ELAN law after the number of unregistered listings in the 18th arrondissement rose from 3,200 in 2023 to 4,800 in 2025. Local government records show that 62 percent of those listings were entire apartments previously available for year-round leases. The registration system gives the arrondissement direct data on which properties are being removed from the permanent housing stock.

Tenants seeking apartments near the Lamarck-Caulaincourt metro station or along Rue des Abbesses will see fewer units advertised for short-term use once the database goes live. Property owners who previously listed units for 120 days or more will have to choose between reducing their letting period or switching to standard residential leases. Families with school-age children living near Square Suzanne-Buisson have reported in community meetings that they already compete with seasonal listings for two-bedroom flats priced under 1,800 euros a month.

Budget allocation and enforcement timeline

The 2026 arrondissement budget allocates 420,000 euros for two additional inspectors and an online verification portal. City data indicate that each unregistered listing removes an average of 1.2 long-term units from the market. Enforcement will begin with a three-month grace period followed by spot checks using the new platform records. The council projects that the cap will return roughly 800 units to year-round rental stock by the end of 2027.

Landlords who register and limit stays to 90 days retain the right to operate, while those exceeding the limit without registration will be removed from platforms after a 30-day notice. Residents can check the status of any address through the arrondissement website starting in August. The next council review of the policy is scheduled for January 2027, when officials will examine compliance figures and any changes in average rents reported by the Paris rental observatory.
