In France, the term “passoire thermique” has become a stark descriptor for poorly insulated homes that leak heat in winter and overheat in summer, placing both tenants and landlords at the center of a growing housing and energy crisis. As energy prices remain volatile and climate goals tighten, owners of these energy-inefficient properties face mounting pressure to renovate—or risk being unable to rent them out at all. The phrase “Nous ne savons plus sur quel pied danser” — “We don’t understand which way to turn” — has emerged among landlords grappling with conflicting obligations, financial strain, and evolving regulations.
This dilemma is not merely anecdotal. According to official data, nearly 5 million primary residences in France are classified as “passoires thermiques,” meaning they fall into the lowest energy performance categories (F or G) on the Diagnostic de Performance Énergétique (DPE) scale. These homes consume excessive energy, contribute disproportionately to carbon emissions, and often abandon tenants struggling with unaffordable utility bills. For landlords, the challenge lies in balancing legal duties, investment returns, and the practical realities of upgrading aging housing stock—particularly in a market where rental yields are already thin.
The French government has responded with a series of phased restrictions under the Climate and Resilience Law of 2021, which sets a timeline for banning the rental of the most energy-intensive properties. Starting in 2025, homes rated G on the DPE will no longer be legally rentable. This will be followed by F-rated properties in 2028 and E-rated homes by 2034. These deadlines are designed to accelerate renovation efforts across the private rental sector, which accounts for a significant portion of the country’s housing stock.
However, many small-scale landlords—often individuals renting out a single apartment to supplement income or prepare for retirement—say they lack the financial means to undertake major renovations. Insulation upgrades, window replacements, heating system overhauls, and ventilation improvements can cost tens of thousands of euros, far exceeding annual rental income for many properties. While state-backed aid programs such as MaPrimeRénov’ and the “coup de pouce” heating boost exist, accessing them involves navigating complex eligibility criteria, paperwork, and contractor coordination—barriers that deter participation, especially among older or less tech-savvy owners.
Adding to the complexity is the perception, voiced in some quarters, that landlords are universally resistant to change or motivated solely by profit. Yet interviews with property owners reveal a more nuanced picture: many express willingness to improve their homes but feel abandoned by a system that imposes strict deadlines without offering proportional support. One landlord in Lyon, who requested anonymity, described the situation as “being told to fix a leaking roof with a teacup while the rain keeps falling.” Others point out that tenants, too, suffer during renovations, facing displacement, noise, and dust—issues that complicate cooperation even when both parties agree on the need for change.
Industry observers note that the success of France’s renovation push depends not only on funding but on trust and clarity. Real estate professionals and housing advocates alike call for simpler application processes, faster disbursement of grants, and clearer communication about what constitutes compliance. Some suggest that intermediaries—such as certified energy auditors or nonprofit housing advisors—could play a larger role in guiding landlords through the renovation journey, from assessment to completion.
Meanwhile, tenants’ rights groups emphasize that energy efficiency upgrades must not become a pretext for rent hikes or evictions. French law already limits how much landlords can increase rent following renovations, particularly in high-demand areas, but enforcement remains inconsistent. Advocates urge stronger monitoring to ensure that public funds intended to improve housing quality do not inadvertently accelerate displacement or deepen inequality.
As the 2025 deadline approaches, the focus is shifting toward implementation. Local governments are piloting “one-stop shop” renovation services in cities like Paris, Marseille, and Lille, aiming to streamline access to audits, financing, and vetted contractors. The national housing agency, ANAH (Agence Nationale de l’Habitat), reports that MaPrimeRénov’ has supported over 800,000 renovation projects since its launch, though a significant portion still targets owner-occupied homes rather than rental properties.
For landlords caught in the middle, the path forward requires more than just financial incentives—it demands recognition of their role as stakeholders in a broader ecological transition. Without addressing their concerns about affordability, fairness, and feasibility, policymakers risk undermining the very goals they seek to achieve: reducing energy poverty, cutting emissions, and ensuring decent, sustainable housing for all.
The next official update on rental energy performance compliance is expected in mid-2025, when the government will release preliminary data on how many properties have been upgraded or withdrawn from the rental market ahead of the G-rated ban. Stakeholders are advised to monitor announcements from the Ministry for the Ecological Transition and ANAH for verified timelines and policy adjustments.
