Renovating a French copropriété: PPT, DTG and grants

Preliminary surveys: collective DPE and DTG

Collective DPE (DPE collectif, building-wide energy performance certificate). It is required for copropriétés whose building permit was applied for before 1 January 2013 (ANIL):

The syndic (building manager) must put the choice of provider on the agenda of the assemblée générale (owners’ general meeting), after competitive tendering (ANIL).

Diagnostic technique global (DTG, overall technical survey). Compulsory since 2017 when a building more than ten years old is placed under co-ownership. In other copropriétés, the syndic must put the question of carrying one out on the agenda (ANIL). It analyses the visible condition of the common parts, the syndicat’s (owners’ association’s) position with regard to its obligations and the list of works needed over ten years, with their cost. The decision to commission a DTG is voted by the simple majority of article 24 (service-public.gouv.fr).

The draft multi-year works plan

The obligation applies to copropriétés more than 15 years old (ANIL). The draft PPT includes in particular the list of works needed to preserve the building, save energy and reduce greenhouse gas emissions. It also gives an estimate of the performance achieved, a rough cost estimate and a ten-year schedule (ANIL).

Exemption: a copropriété whose DTG concludes that no works are needed within ten years does not have to draw up a draft PPT for as long as the survey remains valid (ANIL).

Who votes on what at the general meeting

The two majorities. Article 24 is calculated on the votes cast by co-owners present, represented or voting by post; abstentions do not count. Article 25 requires a majority of the votes of all co-owners, including those absent (service-public.gouv.fr).

The bridge. If a resolution falling under article 25 obtains at least one third of the votes, a second vote may be held by the article 24 majority. For energy-saving works that did not reach this third, a new meeting called within 3 months on an identical proposal may decide by the article 24 majority (service-public.gouv.fr).

After the vote, it is the syndic who signs the contract with the firm, oversees the works and attends the handover (ANIL). The meeting sets the amount above which competitive tendering between firms is compulsory.

MaPrimeRénov’ Copropriété

Conditions (France Rénov’):

• at least 65% main residences for 20 lots or fewer, 75% above that;
• building constructed at least 15 years ago;
• copropriété registered and up to date on the national register;
• energy gain of at least 35%;
• RGE (reconnu garant de l’environnement, environmentally certified) firms, support from an AMO (assistance à maîtrise d’ouvrage, project-management adviser) compulsory, maîtrise d’œuvre (project management by a designer) compulsory above €100,000 of works;
• a prior DTG or energy audit.

The syndic files a single application, receives the grant and distributes it according to the tantièmes (ownership shares). A gas boiler is not funded, except for works voted before 30 June 2025 with an application filed before 30 September 2025. A pilot scheme targets small copropriétés (20 residential lots at most), with a required gain of 15% (France Rénov’).

CEE grants. The Coup de pouce “Rénovation performante de bâtiment résidentiel collectif” (high-performance renovation of a multi-occupancy residential building, sheet BAR-TH-177), funded by certificats d’économies d’énergie (energy saving certificates), can also be used: it requires an energy gain of at least 35% and was extended by the arrêté (ministerial order) of 7 January 2026 for operations started since 17 January 2026. The owners’ association is the beneficiary (Ministry for Ecological Transition).

Which professional to consult

The collective DPE and surveys of the common parts are carried out by a certified diagnostiqueur (property surveyor). If you are buying a lot, the agent immobilier (estate agent) and the notaire (notary) help you gather the PPT and the minutes of general meetings, which announce upcoming works. To finance a share of works, a courtier en crédit (mortgage broker) can compare solutions.
