Multi-annual plan of works (PPT) implemented in condominiums

Verified 01 January 2024 - Legal and Administrative Information Directorate (Prime Minister)

The multi-annual work plan (MWP) is a document developed by the co-ownership to set a schedule of work over a period of 10 years, in particular to safeguard the building and its good maintenance. It concerns condominiums over 15 years of age. It has to be updated every 10 years.

The joint owners' union must put in place a draft multi-annual work plan (MWP) for the end of 15 years from the date of reception of the building.

The building must be for total or partial residential use.

The obligation to establish a draft TPP relates to:

  • Since 1er january 2023, the syndicate of co-owners comprising more than 200 lots for use in dwellings, offices or shops
  • From 1er January 2024, the syndicate of co-owners comprising a number of lots included between 51 and 200 lots for use in dwellings, offices or shops

However, the co-owners' union is dispensed of this implementation if the global technical diagnosis (GTD) shows no need for work during the 10 years following its preparation.


The implementation of a draft TPP will become an obligation for the co-owners' union including 50 lots maximum from 1er January 2025 (unless waived for DTG).

The implementation of the TPP project should be entrusted to a professional with skills and guarantees.

It can be a design office, an architect, a thermician or a real estate diagnoser.

You can find a professional from this directory:

Find a Certified Real Estate Diagnoser

This professional must:

  • certify on the honor of his impartiality and independence with respect to the trustee and with respect to the energy suppliers and companies intervening in the building
  • provide proof of having taken out professional indemnity insurance. It shall specify the competences covered.

The TPP project is based on an analysis of the building's structure and equipment and the energy performance diagnosis (DPE) and possibly DTG if it has been prepared.

The draft TPP should include the following:

  • List of work required to safeguard the building, maintain occupants' health and safety, achieve energy savings and reduce greenhouse gas emissions
  • Estimate the level of energy performance and greenhouse gas emissions performance that the work will achieve
  • Summary cost estimate and prioritization of this work
  • Proposal for a timetable for the work which appears necessary to be carried out in the next 10 years

The work prescribed in the TPP and its timeline and, where appropriate, the work prescribed by the DTG, must be incorporated into the TPP. building maintenance log book.

The trustee must first put on the agenda of the general meeting of the co-owners the modalities for the preparation of the draft multi-annual work plan. These arrangements shall be voted by a majority of the votes of the co-owners present, represented or voting by mail (simple majority).

Then, once the TPP project has been completed, the trustee must submit it to the 1re general meeting of co-owners following its preparation (or revision).

If the draft indicates the need to carry out work within 10 years, the trustee must then put the question of the adoption of all or part of the draft TPP on the agenda of this assembly. This adoption must be voted on by a majority of the votes of all the co-owners (absolute majority).

Please note

If the general meeting has not adopted all or part of the draft TPP or if the implementation of the adopted TPP schedule is uncertain, the trustee will have to put these issues on the agenda of each general meeting called to approve the accounts.

The TPP is to be updated every 10 years.

The mayor or prefect or the president of a public establishment of intercommunal cooperation may at any time ask the trustee to transmit the adopted TPP to verify that the planned works make it possible to guarantee the safety of the building and the safety of its occupants.

If the TPP is not transmitted within 1 months from the notification of the request, the mayor or prefect or president of a public establishment of intercommunal cooperation may develop or update the draft TPP on its own initiative instead of and at the expense of the co-owners' union. The same applies if the plan submitted does not prescribe the work necessary to preserve the safety of the building's occupants.

On receipt of the draft TPP notified by the mayor or prefect or president of a public establishment of intercommunal cooperation, the trustee must convene the general assembly to decide on the question of the adoption of all or part of this draft plan.
