Assistance with your planning permission application

This service is intended to guide you in the constitution of your application filecity planning authorization or site declaration (site opening declaration or declaration of completion and conformity of the work) by following 5 steps:

  1. You describe your project.
  2. The service selects the information you need to fill in.
  3. The service tells you the list of documents that you must attach to your file, with the expected characteristics for each of the documents. The files must be transmitted in PDF, JPEG or PNG format and must:
    • 40 megabytes maximum for building, development and modification permits
    • 20 megabytes maximum for other requests.
  4. You can view and download the finalized online form.
  5. If your municipality is connected, you can upload the file.

The information will be automatically recorded as you proceed on your Service-Public account. You can interrupt at any time and resume the process later.
