How many residential units are possible?

Hello everyone, so we are now planning, at first, to build our little house and the question arises whether we also have to maintain the distance of three meters to our own property boundary? The HBO applies.

That is a pretty simple question: Yes Building law considers each property individually. It doesn’t matter at all who owns them. Now for the restriction/possible solutions (with all advantages and disadvantages): Baulast

This is a fairly simple question: Yes
Building law considers each property individually. Regardless of ownership.

Now the limitation/possible solutions (with all advantages and disadvantages): Easement

That means I could essentially register the easement on the other property: Six meters (in case of construction up to the boundary) distance to the neighboring building?

What does something like this usually cost?

GS with the environment.

I am currently at a loss, what do you mean by GS?

GS = property. What else? The "What else" is just to keep the 5 words.

That means I could enter the building obligation in the other property accordingly:

You devalue the property by doing so. It may no longer be possible to develop the property properly. One does not do such a thing without a plausible reason.

You are devaluing the property with that. It might no longer be possible to build on the property properly. You don't do something like that without a plausible reason.

The property measures 19m x 31m (width x length). If I mentally subtract 6m setback on one side and 3m setback on the other side, the potential house can still have a width of 10 meters. That should be enough for a standard 130-160 sqm house, right?
