Excavation; notification of the start of excavation

You must give prior notice of the start of excavation. 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 when:

  • you start the execution of an excavation requiring a permit, or
  • you continue the execution of the excavation 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 "Notice of Start of Construction" form to the lower excavation authority (district offices and independent cities).
  • A verbal notification is not sufficient.
  • You will not receive an acknowledgement of receipt.
  • The lower excavation authority then checks whether the period of validity of the excavation permit has not yet expired. It may also prepare measures to monitor the excavation, if necessary.

Digital submission

Digital submission of notifications of commencement is currently not yet possible throughout Bavaria. This can only be done at certain lower excavation authorities. You can find out which these are in § 1 Digital Construction Application Ordinance. You can find the link under the tab "Legal basis".

  • The start of excavation can be notified digitally to the lower excavation authority using the online wizard.
  • The predefined form "Start of construction notification" 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.
