Understand the scope

What is this process for?

Signing a lease or purchasing a building does not guarantee the possibility of carrying out every activity there. Environmental or sector-specific authorisations must still be reviewed separately.

How to prepare the process

Contact the competent municipal department with a description and plans of the project. Check the required documents, decisions and notices before work begins. Heritage or environmental constraints may entail additional procedures. Include these checks in the timetable and conditions of the property project to limit premature commitments.
