Declaration of Completion and Conformity of Work (ACCED)
Verified 23 November 2023 - Legal and Administrative Information Directorate (Prime Minister)
You have obtained a city planning authorization (prior declaration, building permit for example) to carry out work and your work is completed? You must complete a Declaration of Completion and Compliance (ACCA). It allows you to inform the city hall of the end of your work. You attest to their compliance with the city planning authorization obtained.
How do I make this statement? We present you the information you need to know to make the process.
Step-by-step approach
If you have obtained a city planning authorization (advance work declaration, building permit or development permit) and your work is completed, you must file a CTAA.
Please note
you must declare the complete or partial completion of the work. Partial completion concerns work in installments, originally foreseen by the city planning authorization. At the end of each installment, you must complete an ACSI.
You must use the following form:
Declaration of completion and conformity of works
You must sign the ACAD or have it signed by the architect when he or she led the work.
Depending on the project, you must attach certificates to the ACFD certifying compliance with certain construction rules.
Accessibility certificate
You must provide an accessibility certificate for the construction of the following new buildings:
- Institution receiving the public (ERP)
- Residential building and its surroundings
- Detached house built to be rented or made available or to be sold
The certificate shall be drawn up by a technical inspector or an architect. The architect cannot be the one who designed the project or drew up the plans or signed the application for a building permit.

For single-family homes, a certified energy performance diagnostic (EPR) diagnoser can write this attestation.

For new residential buildings or single-family houses attached to or superimposed on another premises, you must provide an acoustic attestation.

The City Hall can challenge the conformity of your building with the city planning authorization, by checking on the spot, for a period that varies according to the location of your building.
Your project may be located in a safeguarded area, an area with a historical, aesthetic or nature that justifies the conservation, restoration and presentation of all or part of a set of buildings.
Your project may also be located in an area exposed to natural, technological or mining risks (for example, a landslide, a flood zone or a nuclear risk).
General case

Historical monument or sector saved

Natural, technological or mining hazards

If your construction is not in conformity, the city hall can give formal notice, by post RAR: titleContent, to carry out the necessary work. For this, she may ask you to table a modification building permit.
Warning
if regularization is impossible, the city council can impose the demolition of the building.
Without a response from the City Hall within the deadline, the work is considered complete and compliant.
The method of obtaining an attestation of non-challenge differs depending on whether you are in the province or in Paris.
