Short-Term Rentals in 2025: A New Regulatory and Tax Landscape

Regulatory Context: A Major Shift in the Rental Market

2025 marks a significant turning point for short-term rentals with the enforcement of the Law of November 19, 2024. This new regulation aims to tighten control over tourist rentals while ensuring a balance between property owners, tenants, and local authorities.

Key Regulatory Changes

1. Mandatory Declaration for Primary Residences

Starting May 20, 2026, homeowners renting out their primary residence must:

✅ Register their activity through a national online platform
✅ Provide a tax notice proving the rental address
✅ Adhere to the 120-day annual rental limit

This measure enhances transparency and prevents market abuses, especially in high-demand areas like Paris and Strasbourg.

2. Tax Adjustments: Lower Allowances

For Classified Rentals & B&Bs

🔹 Tax allowance reduced from 71% to 50%
🔹 Applies up to €77,700 in annual rental income

For Non-Classified Rentals

🔹 Tax allowance reduced from 50% to 30%
🔹 Limited to €15,000 in annual rental income

Energy Performance: A Crucial Criterion

Mandatory Energy Performance Diagnosis (DPE)

New obligations for tourist rentals in high-demand areas:

📆 Nov 21, 2024 – Dec 31, 2033 → DPE rating A to E required
📆 From Jan 1, 2034 → DPE rating A to D mandatory

Increased Powers for Local Authorities

Local governments now have broader authority to regulate short-term rentals:

🔹 Rental Duration Limits → Cities can reduce the rental cap from 120 to 90 days per year
🔹 Quota System → Authorities can restrict the number of rental permits in certain areas
🔹 Stronger Penalties → Fines up to €10,000 for unregistered rentals and €20,000 for false declarations

Easier Amendments to Condo Rules

Condo associations can now ban short-term rentals with a ⅔ majority vote (previously required unanimity).

FAQ — Déléguer sa gestion Airbnb à Strasbourg en 2026

Suis-je concerné par l'API Meublés si je loue seulement quelques semaines par an ?

Oui. Dès lors que vous publiez une annonce à Strasbourg, votre activité est transmise mensuellement à la mairie via l'API Meublés à partir de mai 2026. La durée de location ne change pas l'obligation d'enregistrement ni la surveillance automatique.

Que se passe-t-il si je n'ai pas de numéro d'enregistrement ?

Votre annonce peut être suspendue par la plateforme et vous exposez une amende administrative de 10 000 €. Sans numéro, vous n'avez aucune existence légale dans le registre communal — ce qui aggrave les infractions connexes comme le changement d'usage ou le dépassement de quota.

CityCosy peut-il reprendre la gestion d'un bien déjà en infraction ?

Oui. Nous analysons votre situation lors du rendez-vous de prise en charge : statut du numéro d'enregistrement, historique des nuitées, conformité du changement d'usage. Nous accompagnons la régularisation avant de publier les annonces à notre nom.

Quelle est la différence entre une conciergerie et une agence immobilière certifiée comme CityCosy ?

Une conciergerie publie les annonces à votre nom — vous restez responsable de la conformité réglementaire et êtes imposé sur la totalité des revenus encaissés. CityCosy, titulaire des cartes T et G, publie à son nom et porte la responsabilité déclarative. Vous n'êtes imposé que sur le loyer net réellement perçu.
