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.
