Hangstützmauer = Building permit or distance?

Do I need a building permit for a retaining wall along the property boundary to the street or do I have to observe distances?
If distances have to be observed, a wall would not be possible.
The wall is not supposed to support an embankment but naturally grown terrain that was simply cut steeply towards the street and is now only "bordered" by a chain-link fence. That, of course, holds nothing; we want to make it more stable with a proper wall.
Walls are frequently present at the neighbors, so it should be basically possible?
The wall would have to be 2 meters high, that is how high the current cliff or the edge to the upper garden soil is. From there, everything (stones, leaves) falls steeply down and lands behind the fence, where there is already a pile of debris reaching up to half the height of the fence (1.2 m high). The street is therefore 2 meters below ground level. Accordingly, if it concerns naturally grown terrain, the wall could be completely "underground" and therefore no building effect would arise from it?
The federal state is Hesse.

hello

normally a wall up to 1 meter is possible without permission, after that no longer

Hello,

I do not have the Hessian state building code at hand right now, but in the one from Baden-Württemberg it says in the appendix to §50 paragraph 1 - Verfahrensfreie Vorhaben:

Point 7. Enclosures, retaining walls
...
c) Retaining walls up to 2 m height

This corresponds with what the head of the municipal building authority explained to us - retaining walls up to 2 m height are permitted and do not require approval.

I would therefore recommend that you inquire at the responsible building authority how this looks in Hessen. I think I once read somewhere that in Hessen retaining walls are "only" allowed without approval up to 1 m height, but I don’t remember where...

Regards,

Dirk

In Hesse, 1 meter is exempt from approval. We had to chew it over.

Whether artificially filled or natural terrain? And from where does it count, because usually it is calculated above ground level, but doesn't the original ground level always count? Accordingly, a 1m high retaining wall would be about 1 m below ground level for us.

With us, it would have been artificially filled terrain.

However, we only built a 90 cm high wall (for cost reasons).
