Collective DPE for co-ownerships in 2026: the obligation that shakes up rental management

The French Climate and Resilience Act of August 2021 instituted the obligation of collective Energy Performance Diagnostic (DPE) for co-ownerships. The schedule planned a ramp-up: co-ownerships above 200 lots from 2024, above 50 lots on 1 January 2025, all collective-meter co-ownerships on 1 January 2026. In practice, the 50-lot move was postponed by a year — on 1 January 2026, every co-ownership of more than 50 lots must have completed its collective DPE.

What really changes for agencies

The collective DPE is not a single-dwelling DPE multiplied by lot count. It is a global building analysis: envelope (roof, walls, windows), shared systems (collective heating, hot water, ventilation), and shared consumption. The result is a global label that triggers — this is the pivot — the obligation of a multi-year works plan (PPT) if the co-ownership is rated D, E, F or G.

For the building manager, the collective DPE isn't an end in itself: it is a trigger. If the co-ownership is rated F or G, the PPT is mandatory and must be voted at general meeting. If rated D or E, the PPT is recommended but not mandatory. The nuance makes all the difference in pressure on co-owners.

The rental-ban trap

The Climate Act provides a progressive ban on letting energy-leak properties: G from 1 January 2025, F from 1 January 2028, E from 1 January 2034. But the ban applies to the individual dwelling DPE, not the collective DPE. An F dwelling in a D-rated co-ownership can still be banned from being let.

Here is where the real headache for agencies plays out. When a landlord finds out their property is F or G — often on a new lease, hence a recent individual DPE — they have three options: do works in their unit (heating, insulation, windows), align with the collective PPT (which can take 2-3 years), or pull the property from the rental market. None is neutral. And the agency ends up arbitrating in a hurry.

Three blind spots that trip up agencies

Individual DPE / collective DPE mismatch

The same apartment can have an individual D DPE and a collective F DPE. Which applies to the rental ban? The individual one. Which applies to mandatory PPT? The collective one. This distinction is poorly understood by landlords, and agencies spend a lot of time explaining why they are caught in two parallel logics.

2026 energy audit vs DPE

For sale of a F- or G-rated dwelling since April 2023 (individual DPE), an energy audit is mandatory in addition to the DPE. The audit proposes a renovation pathway to reach class C or B. It is more expensive (€800-1,500 vs €200-400 for the DPE alone) and more committing: the audit guides the future buyer toward works they will have to do. Many agencies still confuse the two.

ZAN modifying the trade-offs

Net Zero Land Take (ZAN, 2021 Climate Act, 2031 and 2050 milestones) progressively reduces the possibility to build in urban extension. Consequence: energy renovation of existing stock becomes economically more profitable than new-build. For an investor hesitating between buying a fixer-upper and a new VEFA, ZAN changes the equation. Agencies that integrate ZAN reasoning into their advice become more relevant.

The 2027-2034 scenario

Three deadlines mark the decade. 2028: ban on letting F dwellings. 2031: 50% reduction target for net land take vs the previous decade. 2034: ban on letting E dwellings. For an agency with 1,200 lots under management, that's roughly 200-300 dwellings potentially affected by a letting ban within 8 years, and as many by a structural shift in investor economics.

An agency that wants to hold must transform its landlord relationship: from "manager" to "wealth advisor". This requires tools that cross-reference the DPE, ZAN constraints, the PPT and MaPrimeRénov' Copropriété aids to propose viable trade-offs.
