The global technical diagnosis (DTG)

The global technical diagnosis (DTG)

Co-ownership and DTG

Before the beginning of the year, buildings older than 15 years condominiums were required to have an SRU diagnosis in accordance with the SRU Act of 13 December 2000. Since January 2017 and following the Alur Act, this diagnosis is replaced by a DTG, a global technical diagnosis.

The buildings subject to at this DTG are:

  • those of more than 10 years with a creation of co-ownership;
  • those who are under a procedure of insalubrity and whose administration asks the trustee.

Co-ownership is a division of a building into several private and common lots and changes from one owner to two or more.
The condominiums existing on January 1, 2017 are not affected by the new DTG, however the trustee must still organize a simple majority vote to determine whether a DTG should be practiced or not.

The DTG allows future buyers to know the condition of the building and to have a forecast estimate of maintenance and work expenses.

The content of the overall technical diagnosis and its execution

Many points make up the DTG:

  • An examination of the apparent state of common areas and shared facilities;
  • A statement of the situation of the syndicate of co-owners in relation to legal and regulatory obligations;
  • A study of feasible improvements for the state of the building (technical and heritage management);
  • An energy audit for condominiums of more than 50 lots with general heating or a DPE (energy performance diagnosis) for those with less than 50 lots.
  • A brief estimate of the costs of the work needed for the building conservation over the next 10 years and the list.

The DTG is to be presented to the general Assembly which follows its realization so that the co-owners can look into the development of a multi-year plan of works and the implementation modalities in case of necessary works.
The DTG must be performed by a qualified, insured, impartial and independent professional with the trustee.

Each co-owner has a maintenance book, held by the trustee, gathering technical information on maintenance and work on the building. The list of work done during a DTG must be included in this logbook and the financial plan.

During a unsanitary procedure, the administration can ask the trustee for the DTG to be able to control the state and the security of the common parts. If the DTG is not transmitted within one month of the request or if the syndic refuses to provide it, the administrative authority may request the completion of a DTG at the expense of the co-owners.
