What permission should I have to settle a roof window?

Verified 27 January 2023 - Directorate for Legal and Administrative Information (Prime Minister)

Want to settle a roof window? An application for authorization is required.

The request for city planning authorization is different if your work is accompanied by a change of destination of all or part of the building, for example by transforming a business into a dwelling.

General case

By creating an opening on your roof or changing your roof windows to a different model, you change the exterior appearance of the building. You must file a Advance Work Statement (AD).

You can complete the RFP on the Internet or by using a form.

On the Internet

You should check with your city council or its website to find out if it has an online service to complete your application online.

Who shall I contact

Municipalities with more than 3,500 inhabitants have a specific online service for the seizure and deposit of city planning authorizations.

If your municipality has not set up an online service, you can use an Internet-based support service that guides you through each step of building your file. You can complete and print the DP file using this assistance even if your municipality is not connected to it. From the beginning of the seizure, you will be informed if your municipality is connected.
