Which new homes are covered?

All homes (house or flat, and their annexes) whose building permit or prior declaration was filed from 1 January 2023. The set-up does not matter: CCMI building contract, VEFA off-plan purchase, project manager, self-build with companies. If your permit predates 2023, the obligation does not apply as a new build; it may arise later through energy works.

Who does what between you and the builder?

As always with the CIL: the owner creates the logbook, the professional provides the information. The builder (or the developer in a VEFA) must hand you, at the latest at acceptance of the works, or at delivery of your home in a VEFA (by default in digital format):

  • the surface plans and cross-sections of the home as built;
  • the plans or diagrams of the networks (water, electricity, gas, ventilation) as they actually run through walls and floors;
  • the list and characteristics of the insulation materials (material, thickness, R-value, surfaces per wall);
  • the operating, maintenance and servicing instructions for every system: heating, hot water, ventilation, cooling.

The detailed breakdown of responsibilities: who creates the CIL?

CIL and DOE, two different things. If you hear about the "dossier des ouvrages exécutés" (DOE), that is a contract document, not the CIL. In practice the DOE contains much of what the logbook needs: claim both, pour one into the other.

Checklist at key hand-over

On acceptance day, everyone is available and the documents exist. Six months later, it is another story. So check, on the day:

  1. Surface plans, cross-sections and network plans: handed over, readable, matching what was built;
  2. technical sheets for the insulation (each wall: material, thickness, R-value);
  3. instructions for every piece of equipment, with brand/model references;
  4. the new home's DPE;
  5. the acceptance report (with any reserves) and insurance certificates: not required by the CIL, but worth filing in the same place;
  6. contact details of the companies involved (useful for the one-year parfait achèvement warranty).

If an element is missing, note it in the acceptance report and claim it in writing: the transmission obligation sits with the professional.

Why this is the best moment to create the logbook

A new home is the only case where the property's complete history fits in a single file, available all at once. Creating the CIL at acceptance means starting the home's documentary life at 100 per cent: every boiler service, every small job will simply add to it. At the first resale, the file is unbeatable.
