I often get asked this question by my clients who undertake renovations in their property in France.
Here is the answer:
Under French law, you are not allowed to live in a mobile home unless it is for a holiday purpose or a temporary measure.
If you wish to live in a mobile home whilst your property is being renovated, you will need an authorization from your local mairie. So write a letter to the maire giving of course your name and address and the length of time you need it. Wait for their answer!
You may need a planning permission depending on the size of the mobile home. Don’t worry, the mairie will inform you of the requirement.
If you need any assistance with any paperwork or drafting a letter to the maire, please contact me and I will help you.
