The French real estate market is going through a phase of reorganization where regulatory constraints weigh more heavily than cyclical signals. Understanding the structuring themes of real estate and housing requires going beyond general overviews to identify the real friction points: energy efficiency, tensions in new builds, and asset management decisions related to the energy performance diagnosis (DPE). Here, we offer an analysis guided by recent developments that are concretely altering decisions regarding buying, renting, and renovating.
Energy efficiency and rental bans: the timeline reshaping the rental market
As of January 1, 2025, a property rated G on the DPE can no longer be offered for rent in metropolitan France. The next deadline concerns properties rated F, which will be banned from rental in 2028, followed by E in 2034. This timeline is not theoretical: it directly forces landlords to choose between heavy renovation, sale, or exiting the rental market.
We observe that most owners of energy-inefficient properties have not yet started any work. The cost of a comprehensive renovation often exceeds the planned budget, and public aid only covers a fraction of the bill. For a landlord with a property rated F, the countdown to 2028 necessitates a property decision in the coming months, not in three years.
The themes covered by the entire Immo et Habitat site allow for a cross-analysis of these regulatory issues with questions of financing, taxation, and asset valuation.
Mandatory energy audit for sales: what changes with the extension to E classes
The energy audit, already required for the sale of properties rated F and G, also applies to properties rated E as of January 1, 2025. This document goes beyond the simple DPE: it provides a costed work plan, with scenarios for renovation in stages or as a single operation.
For sellers, the impact is twofold. First, the audit extends the time frame for putting the property up for sale since a certified professional must be commissioned and the report awaited. Second, it gives the buyer a precise negotiation basis on the price, supported by the estimated cost of bringing the property up to standard.
Consequences for real estate negotiation
A buyer receiving an audit listing several tens of thousands of euros in necessary work has a documented negotiation lever. The sale price of energy-intensive properties now includes a structural discount, rather than just a cyclical one. Real estate professionals must incorporate this data into their estimates from the moment they take the mandate.
New housing market in France: a persistent tension in 2026
Sales of new homes reached a historic low in 2025. Reservations at the beginning of 2026 remain down. Several factors are at play: high construction costs, scarcity of land in tight areas, and buyer hesitancy in response to changing borrowing rates.
For developers, the RE2020 has mechanically increased production costs. Stricter thermal and environmental standards translate into exit prices that are difficult for first-time buyers to absorb, even with a zero-interest loan.
Signals to watch for professionals
- Changes in key interest rates: any significant decrease would boost household solvency and, by extension, new reservations
- Local urban planning policies: bioclimatic local urban plans modify construction rules and condition future supply
- Tax incentives for rental investment: the end or renewal of certain tax exemption mechanisms weighs on investor demand
Energy renovation and housing: the technical choices that matter
Energy renovation remains the cross-cutting theme of real estate in 2026. We recommend distinguishing between two often-confused approaches: renovation by gestures (insulation of attics, boiler replacement) and high-performance comprehensive renovation aiming for a minimum jump of two DPE classes.
Renovation by gestures is cheaper in the short term, but it frequently leads to building pathologies. Insulating walls without addressing ventilation causes humidity and indoor air quality issues. Conversely, a comprehensive renovation coordinates insulation, ventilation, and heating production in a coherent project.
Controlled mechanical ventilation: the underestimated aspect
In the majority of renovation projects we analyze, the VMC is addressed last, or even forgotten. This is a serious technical error with significant consequences. Effective insulation without appropriate ventilation degrades indoor air quality and can lead to mold within months. The sizing of the VMC must be integrated from the design phase, alongside the choice of insulation and heating system.
Connected housing and home automation: beyond the gadget
Home automation in housing goes far beyond voice assistants and connected bulbs. Building management systems now allow for the control of heating, ventilation, and openings based on the actual occupancy of the home and weather conditions.
The primary interest is energy-related: a connected thermostat coupled with presence sensors significantly reduces consumption without manual intervention. For condominiums, solutions for monitoring individual consumption, made mandatory by regulations, pave the way for precise management of charges.
The issue of interoperability remains the main barrier. A closed home automation ecosystem limits future developments and exposes the owner to the obsolescence of a brand. We recommend prioritizing open protocols when selecting equipment.
The real estate and housing market is evolving under the combined pressure of energy regulation, tensions in new builds, and the technical upgrading of homes. Both professionals and individuals benefit from addressing these issues in an integrated manner rather than in silos: a purchase project can no longer be reasoned without an energy diagnosis, a rental investment can no longer be evaluated without a decency timeline, and a renovation can no longer be planned without coordination among trades.
