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.


The notification of the start of excavation is not an application. You only have to inform the lower excavation authority about the imminent start of excavation.

The notification of the start of excavation is intended to give the lower excavation authority sufficient time to prepare excavation monitoring measures and to check whether the period of validity of the excavation permit has expired.

Consequences of non-notification

If you intentionally or negligently fail to report the start of excavation at least one week prior to execution, you commit an administrative offense. You can be fined up to 500,000 EUR for this. In addition, the lower excavation authority can order the cessation of excavation.


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 the notice of commencement is currently only possible for excavation projects in the districts of Altötting, Aschaffenburg, Augsburg, Bad Tölz-Wolfratshausen, Cham, Ebersberg, Fürstenfeldbruck, Hof, Kronach, Kulmbach, Main-Spessart, Neumarkt i.d.
