Buy the plot now - build next year.

If you know that you will be building next year, start thinking about the [Bauherrenhaftpflicht] right away. With us, for example, everything is covered under the [Bauherrenhaftpflicht]. Insurance duration: 2 years. That way, you don't have to run around twice.

An interesting question here would be the answer regarding the fence. Does the land have to be fenced in?

Check the liability policy once, with many insurers an undeveloped plot of land is also covered.

The background is as follows: On my side of the road (country road) there is no sidewalk/bike path. Do I still have to clear a strip of 1 meter?
On the other side of the road there is a pedestrian/cyclist path.

What would something like that approximately cost?

We are obliged to clear 1.5m along the property boundary and pay just under €400 per winter for about 50m of property frontage. Asking the future neighbor could be significantly cheaper for smaller areas and regions with relatively few snow days.

Check the liability insurance policy, in many insurances an undeveloped property is also covered.

That is exactly the case with us.
