- Sending one paper copy when the form asks for 3.
- Copying the wrong permit number.
- Waiting until the end of works. It must be sent when the works start.
- Mixing up the DOC and the DAACT (cerfa 13408), which is filed when works end.
- Forgetting building damage insurance (dommages-ouvrage). The form says the beneficiary must have proof of it when the site opens, unless building for himself or close family.
