Excavation; notification of the start of excavation

You must notify the start of excavation in advance. This applies to the start of execution of projects requiring approval as well as the continuation of execution after an interruption of more than 6 months.



You must notify the start of excavation if:

  • you begin excavation work requiring a permit or
  • you continue excavation work after an interruption of more than 6 months.

This also applies to a project covered by a partial excavation permit.


Written submission

  • Submit the completed and signed "Construction start notification" form to the lower excavation authority (district offices and independent cities).
  • A verbal notification is not sufficient.
  • You will not receive a confirmation of receipt.
  • The lower excavation authority will then check whether the period of validity of the excavation permit has not yet expired. It can also prepare measures to monitor the excavation if necessary.

Digital submission

Digital submission of commencement notifications is not yet possible throughout Bavaria. This is only possible with certain lower excavation authorities. You can find out what these are in Section 1 of the Digital Building Application Ordinance. You can find the link under the "Legal basis" tab.

  • The start of excavation can be notified digitally to the lower excavation authority using the online assistant.
  • The prescribed "Notification of start of construction" form is replaced by the queries in the online assistant.
  • Signatures are replaced by authentication using the "BayernID" user account.


You must notify the start of excavation at least one week before the start of execution.
