Registration requirements

●
City hall registration — French law provides for prior registration of tourist rentals. Confirm the applicable online service and required documents with the municipality.
●
Registration number — The registration number must appear on all your listings (Airbnb, Booking, etc.). Platforms are required to verify it.
●
Energy Performance Certificate (DPE) — For properties requiring a change-of-use permit (secondary residences), a minimum class E DPE is mandatory since 21/11/2024 (loi Le Meur Art. 3). For primary residences, no DPE is required at registration. The F/G ban from 2028 applies to long-term residential leases, not to short-term tourist rentals.

Furnished rental income is declared under micro-BIC regime or actual expenses. Since loi Le Meur (n°2024-1039): 50% allowance for classified tourist furnished rentals, 30% for non-classified (EUR 15,000 cap). Tourist tax is collected automatically by platforms.

Compliance checklist

1
Check your property status
Determine if it is your primary residence (8+ months/year) or secondary. Rules differ considerably.
2
Register with city hall
Complete your registration and obtain your 13-digit registration number at your city hall. The national host portal (API Meublés, DGE) is expected in the 2nd half of 2026 - until it opens, registration is done directly with your local city hall.
3
Display number on your listings
Add your registration number on all platforms (Airbnb, Booking, Vrbo, etc.).
4
Obtain energy certificate
If your property is a secondary residence subject to change-of-use, obtain a DPE: minimum class E is required by loi Le Meur Art. 3. For a primary residence, a DPE is not required at registration.
5
Declare your income
Declare your rental income under BIC (micro-BIC or actual). Tourist tax is collected by platforms.
