French Rent Control (Encadrement des loyers) in tense areas

France's 'Encadrement des loyers' limits rent increases in designated 'tense areas' (zones tendues) for primary residences and mobility leases. In most of these areas, landlords cannot freely increase rent upon tenant change or lease renewal. In some major cities, rent levels are capped based on reference rents. This measure aims to control rent prices and ensure affordable housing.
