Wait with the building application because of the child construction allowance

If you are sure that you are below the income limit, then yes. Although it is not certain whether there will be anything starting from 1.08.

We also did not need a building permit, everything was done with a notification.

O.k then I should wait with the building application or with the signature at the contractor (or both!?) until the child is born, right?

The child is due on 1.8, we actually wanted to start building earlier

I can only give you my opinion, because these details have not been settled yet. It should be clear that there is a connection to children. For safety’s sake, I would personally also wait.

However, you have to think this through further...

Example: You receive the child building allowance because the building permit is granted on 01.10.2018 and you already have one child. What happens if a second child is born on 01.10.2019?

In my opinion, the child building allowance is also granted for the second child but not for the full 10 years, only for 9 years, because the child building allowance is paid for 10 years starting from the building permit.

9 or 10 years would be fine with me.
The main thing is that the 2nd child is included as well.

How do you understand the building application when building under the approval-free procedure? According to current information, when is the deadline?

This is stated in the short paper of the CDU/CSU parliamentary group and SPD. From the moment the building authority learns about your new construction project, but at the latest from the moment you can start building.

"where I can build" would then be from the building notification? So we submitted the documents completely on 30.11.2017 and would have been allowed to start at the earliest after the expiration of the one-month period (28.12.2017?); provided that we make a building notification one week before the start of construction. We then made the building notification in March 2018. One week later we were allowed to build. What now counts as the date? Unfortunately, I do not understand it.
