A Paris, a 50 m² apartment listed at over 500,000 euros three years ago is now trading significantly below that price. The median price per square meter in Paris stands at 10,826 euros in August 2026, down from 11,001 euros a few months earlier. This slow decline, which has been in place since 2023, is reshaping the balance of power between buyers and sellers in the capital.
Thermal sieves in Paris: the depreciation that average prices do not show
The median figures mask a phenomenon that is increasingly impacting Parisian transactions. Since January 1, 2025, the Climate and Resilience Law prohibits the rental of properties classified as G in the energy performance diagnosis. In Paris, where the older housing stock predominates, this ban affects a considerable volume of properties.
Have you spotted an attractive Haussmann-style apartment in the 10th or 18th arrondissement? Check its DPE classification first. Properties classified as G experience a depreciation of 15 to 22% compared to better-rated equivalent properties, typically classified as C or D. For properties classified as F, the observed depreciation remains more moderate, between 8 and 15%.
This situation creates two parallel markets. On one side, energy-efficient renovated apartments that maintain their prices. On the other, energy-intensive properties whose owners struggle to find buyers at the expected price. For a buyer willing to finance energy renovation work, this is a concrete negotiation lever, provided they accurately estimate the cost of the work before making an offer.

Real estate prices in Paris by arrondissement: widening gaps
The price range in Paris goes from 8,916 euros per square meter in the cheapest arrondissements to 16,177 euros in the most sought-after areas. This gap, close to double, has widened in recent years.
The arrondissements where the average price falls below 10,000 euros per square meter are no longer an exception. In 2024, the symbolic barrier was crossed in about ten arrondissements. This trend has continued since, although the decline is slowing.
What the prices by arrondissement do not reveal
An average price per square meter by arrondissement remains a rough figure. Within the same arrondissement, the difference between a ground-floor apartment facing a dark courtyard and a top-floor apartment with cross-ventilation can exceed 30%. The floor, brightness, presence of an elevator, and DPE classification weigh as much as the postal address.
Comparing listings within the same street provides a more reliable benchmark than an arrondissement average. Listing portals allow for this comparison, provided you filter on homogeneous criteria (surface area, floor, condition).
Paris real estate market 2026: stabilization or blockage?
Over the year, median prices have increased by 1.9%, rising from 10,625 euros in 2025 to 10,826 euros in August 2026. This modest increase might give the impression that the market is recovering. The reality is more nuanced.
The Notaires du Grand Paris describe a situation that some analysts call a “false calm.” Prices are no longer dropping sharply, but market liquidity is deteriorating. Specifically, the average selling times have extended beyond three months. Some sellers refuse to lower their prices further, while buyers remain cautious due to credit rates. The result: fewer transactions are completing.
This partial blockage mainly affects properties whose listed prices do not match the value perceived by buyers. Well-priced, renovated apartments with good DPE ratings continue to find buyers within reasonable timeframes.
Real estate purchase in Paris: three criteria to check before signing
Rather than a list of general advice, here are three points that can sway a Parisian acquisition in 2026.
- The DPE classification and the actual cost of bringing it up to standard. A property classified as F or G offers room for negotiation, but insulation work in a Haussmann building often costs more than expected. Request a quote before making an offer, not after.
- The rent-mortgage differential on your target area. In Paris, the median rent is 41 euros per square meter. Compare this amount to the mortgage payment for an equivalent area. If the monthly payment significantly exceeds the rent, the question of “buying or renting” deserves a real calculation based on your expected holding period.
- The ability to absorb an extended resale timeframe. With selling times stretching out, buying a property that you may need to resell in two or three years exposes you to a risk of loss. Notary fees alone represent several years of potential capital gains at the current pace.
Estimation and negotiation: the listed price is not the sale price
The average surface area purchased in Paris has fallen to 46.4 m², a level comparable to 2006. The average transaction amount has also declined, returning to a level seen in 2015 with an average of 410,000 euros. These figures confirm that Parisian buyers are purchasing smaller and negotiating harder than a few years ago.
Estimating a property by a single agent is no longer sufficient. Cross-checking at least two or three estimates, then comparing the result to actual sale prices (not listed prices) in the same neighborhood provides a solid negotiation basis.
The Parisian market of 2026 rewards preparation. A buyer who arrives with a completed financing file, a precise understanding of the DPE of the targeted property, and an estimate based on actual transactions in the neighborhood negotiates from a position of strength, even in the most sought-after arrondissements.
