A landlord who discovers that their property rated G can no longer be rented out since January 2025 experiences a concrete shift: energy regulations no longer just set goals; they remove properties from the rental market. This constraint reshapes the priorities of the housing sector in 2024 and beyond, far beyond the announcements about connected homes or bio-sourced materials.
Prohibition of renting thermal sieves: what it changes on the ground
Since January 1, 2025, any property rated G on the energy performance diagnosis (DPE) is prohibited from being rented in mainland France. No new lease, no renewal of an existing lease. We are no longer talking about incentives: a G-rated property removed from the rental market no longer generates income.
For landlords, the question is no longer “should we renovate?” but “in what order should we tackle the work?”. Scenarios for renovation (insulating the attic first, then changing the heating system, then windows) become the operational norm. RGE craftsmen are seeing an increase in requests for bundled quotes, where owners previously ordered work item by item.
At the same time, the sale of a property rated E must now be accompanied by a regulatory energy audit since January 2025, whereas the obligation previously only applied to classes F and G. You can follow Habitat Vision’s news to see how these regulatory constraints are concretely reshaping the market.
Energy renovation and public aid: balancing between gesture-based pathways and global renovation
MaPrimeRénov’ remains the central scheme, but its terms have evolved. The “gesture-based” pathway allows for funding a single intervention (heat pump, wall insulation), while the accompanied pathway targets a global renovation with a gain of at least two DPE classes. On the ground, the choice between these two pathways depends on the available budget and the starting energy class.
A property rated F often benefits from aiming directly for a global renovation to move to D or better, which secures its rental value and resale value. A property rated D with a single weak point (an old hot water tank, for example) can settle for a single gesture.
Feedback varies on this point: some craftsmen systematically recommend the accompanied pathway to increase aid, while others find that the processing times extend projects by several months. Before committing, it is essential to check the order of procedures, as starting work before the aid application is validated can result in the loss of funding.
Priority work items
- Thermal insulation (attics, walls, ground floors) remains the gesture with the best cost/effectiveness ratio for most old properties.
- Replacing the heating system with a heat pump or a hybrid system allows for a shift away from fossil fuels, a criterion increasingly monitored by the DPE.
- Controlled mechanical ventilation (double-flow VMC) is often overlooked, while good ventilation prevents humidity-related issues after enhanced insulation.
- Windows and doors come last in the efficiency hierarchy, except in cases where single glazing is still in place.
Climate adaptation of buildings: preparing the housing stock for a warmer France
The third National Climate Change Adaptation Plan (PNACC-3) places buildings at the center of its priorities. The stated goal: to adapt the French housing stock to a four-degree warming scenario. We move from a winter energy performance logic (heating less) to a summer comfort logic (not overheating).
Concretely, this pushes developers and renovators to integrate fixed solar protections (sunshades, facade canopies), green roofs, and materials with high thermal inertia. Summer comfort becomes a design criterion on par with winter insulation.
In dense urban areas like Paris or Bordeaux, top-floor apartments remain the most exposed. Recent heat waves have shown that these apartments regularly exceed comfort thresholds, even with good insulation. The addition of night-time over-ventilation or reflective exterior blinds is part of the on-the-ground solutions that are becoming widespread.
Participatory housing and social housing: sectors that are moving despite the crisis
The social housing sector, supported by the Union Sociale pour l’Habitat (USH), faces a tension between the need to build and rising construction costs. The figures for participatory housing produced in 2024 during the National Meetings in Rennes show that this form of housing continues to develop, despite the crisis affecting the production of new homes.
The average duration of a participatory housing project is 3.6 years before delivery. This timeframe, often underestimated by project leaders, explains why groups that started before the crisis are now delivering, while those starting today will have to deal with a tighter financial context.
- Social ownership projects remain the most numerous, supported by local authorities that provide land.
- Mixed arrangements (free ownership + social rental in the same building) are multiplying to balance budgets.
- Support from specialized structures significantly reduces the abandonment rate of projects in the design phase.
The HLM sector, with its stock of several million homes, represents a major lever for the energy transition. Renovating this stock on a large scale requires heavy financial trade-offs, and HLM organizations must juggle between maintaining affordable rents and investing in thermal performance.
The housing trends for 2024 are not limited to spectacular innovations. The effective prohibition of renting a G-rated property, the extension of the energy audit to class E, and the adaptation of buildings to climate change: each measure produces concrete effects on how we build, renovate, and inhabit. The French real estate market is transforming under regulatory pressure, and owners who anticipate these deadlines protect both their assets and their ability to rent or sell.
