This declaration shall be mandatory at the end of the work authorized by building permit, a development permit or prior declaration of work.. Only demolition permit is not affected by this declaration.

The Date shall specify whether the completion concerns the entire work or a slice of the work according to an authorized program. For example, in the case of the staggering of work in the context of the construction of dwellings in the future state of completion..

At the end of each project, a Dact is sent to the town hall.

The Notification must be made by means of a form.

For all construction or extension work subject to building permits, a certificate must be attached to the Dact indicating that the construction complies with the 2012 thermal regulations (RT 2012).

This certificate must be completed, on request, by a qualified professional. This can be an architect or, for individual houses, an accredited diagnoser for the realization of energy performance diagnostics (EPR).

City hall officials may issue a letter to the planning authorization holder requesting the necessary works or asking him to file an amending building permit. If they find an anomaly within the 3 and 5 months following the authorization granted, they can request it.

The authorization holder may request a certificate certifying that the conformity of the work has not been contested where no decision has been taken within the 3 or 5 month period. This request must be sent to the town hall by mail (simple or recommended). This certificate (if not contested) is issued within 15 days. These delays can be reduced by calendar days..

In case of refusal or silence of the town hall, it is necessary to request a certificate from the prefect of his department.
