Since January 1, 2025, the French real estate sector is entering a new era. The changes go beyond a simple revision of previous rules. They reflect a political will to strengthen ecological requirements and adapt the tax framework to an uncertain economic context. The ban on renting energy-rated G housing, for example, embodies this priority given to the energy transition. At the same time, major fiscal upheavals, such as the end of the Pinel scheme or the postponement of the Zero-Rate Loan, are redefining incentives for investors and households. Finally, the continuation of the "anti-Airbnb law" and the stability of notary fees complete this picture of reforms, where each measure shapes the delicate balance between the expectations of property owners, the needs of tenants, and environmental imperatives. These adjustments, far from being anecdotal, herald a profound transformation of the real estate market.
