ᐅ Filling a Sloped Plot to Create a Level Surface – Is a Building Permit Required?

Hello everyone,

I own a plot of land in Bavaria with an area of 600 m² (7,292 ft²). It is a south-facing slope that I would like to raise using the excavation material from the construction. The land drops a total of 170 cm (67 inches). Retaining walls would still need to be built.
Towards the street, the land is level and slopes further down towards the garden at the back.

Do I need a building permit / planning permission for this?

Regards,
Christian

A significant embankment like yours always requires a building permit / planning permission. You can easily verify this yourself in the BayBo regulations. The only exception is if there is a development plan that allows otherwise.

Up to 500m2 (5380 sq ft) and 2 meters (6.6 ft) they are permitted as a neighbor, but I would not tolerate that.

Just make steps.

You don’t have to build up the level completely flat. It is perfectly fine to let it slope downward by half a meter (about 1.5 feet) or even more toward the back. A retaining wall of 1.20 m (4 feet) already looks quite different in terms of cost and appearance compared to one of 1.7 m (5.5 feet).

Either it is allowed or it is not: if it is allowed, it doesn’t matter whether the neighbor tolerates it or not....

Many people seem to think they have a say about their neighbors’ buildings – but the opinion simply doesn’t matter as long as the requirements (law, zoning plan, setback distances, etc.) are met.

As a layperson, I also assumed that you could nicely spread the excavation soil on your own property. However, the structural builder and site manager disagreed and had it removed because it was clay soil. Maybe first clarify the quality of the excavation soil.

It doesn’t matter what quality you use; you can always add a 15cm (6 inches) layer of topsoil.

The 2 meters include the fence, and it definitely needs to be there as a fall protection ^^

Of course, they are legally on the safe side, but the neighborhood is also important.
