France has a new kind of property hotspot. It is not a city, a neighborhood, or a fancy development.
It is an energy rating.
In 2026, the DPE rating is no longer “nice to know.” For landlords, it is a compliance gate that can decide whether a home is rentable. For buyers, it is quickly becoming a pricing lever, a negotiation weapon, and in some cases, a forced sale trigger.
France’s energy decency rules are now creating a clear split between two buckets of housing.
Housing that can be rented, refinanced, and held with low legal friction
Housing that is legally risky to rent unless upgraded, and therefore must be bought with a renovation plan, or avoided
The timeline is simple, and it is already live.
Since January 1, 2025, it is prohibited to rent accommodation labeled G on the DPE for leases signed, renewed, or tacitly renewed from that date
From January 1, 2028, homes labeled F will also be considered indecent and cannot be rented
From January 1, 2034, homes labeled E will also be considered indecent and cannot be rented
This is why the DPE is now a market signal, not a footnote.
At January 1, 2025, France had 31.7 million primary residences.
The estimated number of “passoires énergétiques” in primary residences, meaning DPE labels F and G, was about 3.9 million homes, or 12.7% of the stock. That figure was down about 327,000 versus January 1, 2024, and down 836,000 versus January 1, 2023.
The distribution of primary residences by DPE label at January 1, 2025 was:
A: 3.3%
B: 5.3%
C: 27.2%
D: 33.7%
E: 17.8%
F: 7.9%
G: 4.8%
The punchline for investors is straightforward. If your strategy depends on renting, the DPE label is part of your underwriting, just like loan terms and taxes.
The best opportunities are not “cheap homes.” They are discounted homes where the discount is larger than the real cost and complexity of making the asset compliant.
That opportunity tends to cluster where three things overlap:
A large share of older housing stock
Durable rental demand that is not just a tourism story
Renovation feasibility, meaning you can actually execute inside building and local constraints
A concrete example of how regional housing stock can skew: in Hauts de France, an Insee analysis found that in 2022, 42% of primary residences were rated E, F, or G. The share rated E was 26%, and the share rated F or G was 16%. In that same analysis, Insee notes that only Bourgogne Franche Comté and Normandie exceeded Hauts de France, each with more than 43% of homes rated E, F, or G.
That is the structural setup for a long runway of renovations and pricing dispersion.
DPE creates a widening spread between “ready to rent” and “needs work.”
In practice, the spread comes from four forces:
Legal ability to rent, which directly affects investor demand and valuation
Renovation friction, including timelines, contractor capacity, and copropriété constraints
Financing and liquidity, because some buyers and lenders become more conservative around energy risk
Tenant preferences, since utility costs and comfort matter more when budgets are tight
This is why two apartments on the same street can trade at very different prices in 2026, even if the floor plan is similar.
If you only do one thing, do this. Treat DPE risk like a deal breaker until it is proven manageable.
What is the current DPE label
When was it issued
Are you buying with an existing tenant, and if yes, when is the next renewal window where compliance risk becomes unavoidable
A DPE upgrade is not a single project. It is typically a stack of choices.
Common levers that can materially improve performance include:
Insulation and air tightness improvements
Window and door upgrades
Heating system changes
Hot water system efficiency
Ventilation and moisture management
The right mix depends on the building, not on a generic checklist.
Even if you have the budget, the building might block you.
Can you change windows
Can you alter facade insulation
Are there restrictions that push you into more expensive internal solutions
How long do approvals typically take
This is where most investors get trapped.
If renovation becomes delayed or blocked, what is the Plan B?
Sell quickly, and at what likely discount
Hold as owner occupied only, if that fits your goals
Pivot to a use case not impacted by the same rental rules, only if you have verified legality and viability
If the deal only works in the best case, it is not a deal. It is a gamble.
This market rewards investors who underwrite at the address level and plan at the timeline level.

“For this address in France, what is the DPE risk profile, and how does the 2025, 2028, 2034 rental timeline affect my ability to rent over the next 10 years?”
“Give me a compliance roadmap to move this property from G or F to at least D, list the highest impact renovation levers, and flag any building level constraints I should investigate.”
“Model two scenarios: renovate and rent, versus do not renovate and sell later, then show a conservative 5 year return range and the biggest downside drivers.”
“Compare three French areas I am considering, rank them by rental demand durability, older stock exposure, renovation execution risk, and likely liquidity if I need to exit.”

France in 2026 is not a single market. It is a two speed market shaped by energy compliance.
If you understand the rules, and you underwrite renovation feasibility with discipline, DPE driven discounts can become a genuine edge. If you ignore it, you can accidentally buy a property that is difficult to rent on the exact timeline your strategy depends on.
Q1. What is the DPE and why does it matter for rentals in France in 2026?
The DPE (Diagnostic de Performance Énergétique) rates a property’s energy efficiency from A to G. In 2026, it directly determines whether a home can be legally rented, making it a compliance gate rather than an informational label.
Q2. Which DPE ratings are illegal to rent in France?
Since January 1, 2025, properties rated G cannot be rented for new, renewed, or tacitly renewed leases. From January 1, 2028, F-rated homes will also be banned, followed by E-rated homes from January 1, 2034.
Q3. Does the DPE rental ban apply to existing tenants?
The ban applies when a lease is signed, renewed, or tacitly renewed. Properties with sitting tenants may remain occupied temporarily, but compliance risk becomes unavoidable at the next renewal window.
Q4. How many homes in France are affected by DPE F and G ratings?
As of January 1, 2025, around 3.9 million primary residences—about 12.7% of the housing stock—were rated F or G. While the number is declining, the exposure remains significant for rental investors.
Q5. Why are DPE ratings now affecting property prices?
DPE ratings influence legal rentability, financing appetite, renovation costs, and tenant demand. This creates a widening price gap between properties that are immediately rentable and those that require upgrades to remain compliant.
Q6. What regions in France have the highest DPE risk exposure?
Regions with older housing stock show higher exposure. Hauts-de-France, Bourgogne-Franche-Comté, and Normandie each have more than 43% of primary residences rated E, F, or G, creating both risk and renovation-driven opportunity.
Q7. Is buying a DPE F or G property always a bad investment?
Not necessarily. These properties can offer attractive entry pricing if the renovation cost, timeline, and feasibility are well understood. The opportunity exists where the market discount exceeds the true cost and complexity of compliance.
Q8. What renovations actually improve a DPE rating?
Meaningful upgrades usually involve a combination of insulation, window and door improvements, heating system changes, hot water efficiency, and proper ventilation. The correct mix depends on the building, not a generic checklist.
Q9. Why are copropriété and heritage rules a major risk?
Even with sufficient budget, renovation may be blocked or delayed by building-level approvals or heritage restrictions. These constraints can force more expensive internal solutions or make certain upgrades impossible.
Q10. What happens if a property cannot be renovated in time?
Investors should plan for downside scenarios, including selling at a discount, holding as owner-occupied housing, or exiting before compliance deadlines. If a deal only works assuming smooth renovation, it carries significant risk.
Q11. How should investors underwrite DPE risk in 2026?
DPE risk should be treated like financing or legal risk. Investors should verify the current label, lease timelines, feasible renovation levers, approval constraints, and exit options before committing capital.
Q12. Why is France described as a two-speed housing market in 2026?
Energy compliance has split the market between homes that are legally rentable with low friction and those that carry regulatory, renovation, and liquidity risk unless upgraded. Pricing increasingly reflects this divide.
Q13. How can GRAI help investors manage DPE risk in France?
GRAI analyzes DPE compliance timelines, renovation feasibility, and downside scenarios at the address level. It helps investors compare renovate-versus-sell outcomes and identify regions where DPE-driven discounts offer real, defensible upside.
