A political group in France, La France Insoumise, has unveiled a detailed housing and rent control plan as part of its campaign for the 2027 presidential election. The proposal, published on September 28, aims to create 400,000 affordable housing units each year for five years, including 200,000 public housing units. Of these, 140,000 would be financed through the PLAI (Aided Integration Lease), a program that provides financial support for low-income renters. The plan also seeks to increase the availability of existing housing by requisitioning vacant units, repurposing old buildings, and limiting short-term tourist rentals. These measures are expected to provide an additional 150,000 housing units annually. The transformation of unused offices, shops, and other spaces into homes would contribute another 50,000 units each year. Local governments that build housing would receive extra funding, and the threshold of the SRU (Urban Renewal and Housing) law, which requires a certain percentage of social housing in cities, would be raised to 30%, with calculations based on districts in large metropolitan areas. Municipalities that fail to meet these requirements could face stronger sanctions. A key goal of the plan is to enable households to purchase their homes. This would be supported by a "solidarity real lease," which involves using public land and offering subsidized loans to organizations that help people buy homes. A public banking hub would also provide subsidized loans for first-time buyers, with clauses to prevent speculation and reduce the personal financial burden. The plan also includes measures to regulate land prices and strengthen public agencies that manage land. These steps aim to make home ownership more accessible, especially for lower-income families. For existing housing, the plan targets the renovation of insulation in at least 700,000 homes annually, with a focus on comprehensive improvements. Public funding would cover 100% of the costs for the most vulnerable households, with support decreasing as income rises. Homeowners with more than five properties would be excluded from the program. The remaining costs could be financed through long-term loans or deferred payments. A single public service would assist homeowners with the process, and energy efficiency would be a condition for receiving ecological labels. The plan also emphasizes summer comfort, requiring private landlords and large social housing providers to identify and address overheating risks in homes. Equipment such as shutters, blinds, or air circulators would be provided to affected tenants, and a legal right to protection from extreme heat would be established. For property professionals, the plan introduces significant changes. All rental listings would require a rental permit, and measures would be taken to detect and penalize thermal inefficiencies. A new tax would be introduced on vacant properties, with the rate increasing based on the number of unoccupied units. Tourist rentals would be limited to 60 days per year, with stricter restrictions in high-demand areas and a complete ban in the central areas of major cities. The plan also proposes a progressive land tax based on total real estate holdings and limits inheritances to five housing units. Any properties inherited beyond that limit would be seized by the state and allocated to social housing or programs run by solidarity land agencies. Specific implementation details are still to be worked out. In terms of financing, the plan projects an additional 12 billion euros in annual investments by the state, supported by a public banking hub and other financial actors, particularly through loans. Rent control would be expanded nationwide, with stronger enforcement and harsher penalties for landlords who exceed rental caps. In a September 3 statement, La France Insoumise outlined Jean-Luc Mélenchon's intentions on rent control, including the creation of a housing inspection system similar to the labor inspection, to ensure compliance with the new regulations.
