Collective energy survey: what a small French copropriété must do

Since 2026 the obligation covers every residential copropriété, including the six-lot building run by a volunteer. The timetable, the vote and the real cost.

Collective energy survey: what a small French copropriété must do

An eight-lot copropriété in a 1970s building holds its spring general meeting without a care. The volunteer syndic presents the accounts, the hallway repainting is approved, everyone goes home. Three months later, putting together a grant application for loft insulation, that same volunteer discovers the file cannot be accepted: it is missing a survey nobody had ever heard of. Since 1 January 2026, the collective energy performance survey (the DPE collectif) has been compulsory for every copropriété used mainly for housing whose building permit predates 1 January 2013. Large blocks were caught in 2024, buildings of 50 to 200 lots in 2025, and small copropriétés, the ones with neither a professional syndic nor a well-staffed council, bring up the rear.

Who is covered, and who is not

The obligation attaches to the building, not to the number of owners. If the block is mainly residential and its building permit predates 1 January 2013, the collective survey applies whether there are eight lots or two hundred. Two situations fall outside: buildings permitted after that date, first, and second a copropriété that already holds a collective survey still within its validity period, which has no need to commission another until it expires.

Do not confuse this document with the individual DPE you had drawn up to sell or let your own flat. The collective survey covers the whole building (envelope, roof, communal heating and ventilation) and provides the technical basis for the works voted at the general meeting.

What it contains and how long it lasts

The survey rates the building, estimates its consumption and emissions, and above all sets out prioritised works recommendations. That last part is what matters to the copropriété: it turns a shared hunch ("the place is a sieve") into a costed, ordered list. It is valid for ten years, and a copropriété whose survey lands in class A, B or C is spared renewal during that period, but the clock restarts when it expires.

Note: the collective survey does not replace the individual DPE required for a sale or a letting. The two coexist, with different scopes.

The vote at the general meeting and the real cost

Commissioning the survey is voted at the general meeting by the simple majority of article 24 of the law of 10 July 1965: a majority of the votes of the owners present or represented. It is the most accessible majority in French co-ownership law, and getting the item onto the agenda is the only real difficulty. On budget, the order of magnitude is reassuring for small structures: for a copropriété of two to ten lots, quotes typically land between 500 and 1,200 euros in total, roughly a hundred euros per lot, and beyond that the price climbs with the size and complexity of the building. The cost is shared between owners according to their tantièmes, like any other common charge.

Get quotes from two or three certified surveyors and ask to see a report they have already delivered. The quality of the recommendations varies far more than the price does, and a rushed report produces an unusable works plan, which means the money was spent for a document that will sit in a drawer while the building keeps leaking heat exactly as before.

What happens if the copropriété does not have one

There is no automatic fine for a copropriété that has not commissioned its survey. That explains why so many buildings let it slide.

It is a short-sighted reading, because the real consequences lie elsewhere.

Without the collective survey, the copropriété is working blind on three fronts at once:

  • Drawing up the multi-year works plan, which has to rest on a technical assessment of the building
  • Access to renovation grants, several of which require the survey as part of the application
  • The liability of the syndic, volunteer included, for failing to put the question on a meeting agenda

That last point deserves stating plainly to anyone running their own building: a volunteer is no less answerable than a professional for the obligations they let slip. They are simply less well informed, which has never worked as a defence.

From survey to works to funding

The collective survey is not one more piece of paper: it opens a sequence.

The survey establishes the state of play, the multi-year plan schedules and costs the work over ten years, and the works fund built up each year pays for what has been scheduled.

Taken separately, the three obligations look like paperwork imposed from above. Chained together, they do exactly what an ageing building needs: identify what will fail, in what order, and have money set aside before it does.

For a building run by a volunteer syndic, the sensible move is to handle all three in the same meeting: vote the survey, plan to put the works schedule on the next agenda, and adjust the contribution to the fund accordingly.


The 2026 obligation has at least forced a conversation many small copropriétés had been postponing for years. Get three quotes, vote the survey at the next meeting, read the recommendations before filing them, and use them to build your works plan. The document costs a few hundred euros; ignoring it costs lost grants and works decided in a panic.
