3m distance limit from the house to the property boundary

11ant just means: if there is no development plan, the building authority can still have an idea of a distance in front of the house so that there is a good sightline on the street.

is there a plan? If not, just talk to the building authority. Maybe you can have a good conversation with them.

Since the elephant is getting lost in conjectures and Yvonne is bent on confrontation, here are a few counterquestions: - Which federal state? The legal excerpt certainly does not come from the current state building regulations of Schleswig-Holstein or Saxony-Anhalt. - Is there a development plan? - Is the "green area of the city" a public traffic area? At least in NRW, this would have to be officially designated as public. Or is this area considered a public green space? Or is it a private area belonging to the city? - the municipality must answer this - How large is the distance of the neighboring house to the street? Here is also my conjecture: Even if a street-side boundary construction were legally permissible (distance areas), it would not be approved from a planning and traffic perspective.

So, to make it understandable for the OP:

If there is a development plan, one typically only reads in the "textual provisions" which side boundary setbacks are required when and can only deduce the recession of the building front from the street from the graphical version of the development plan. There, you can see it as a blue frame line spanning several plots, the so-called building window. Sometimes this frame line on the street side is not blue but red. Then it is not a building boundary but a building line. That means you are not allowed to build up to a maximum distance but must build exactly up to it.

If, as a layperson, you have already read a bit in forums, you have probably come across the term "building window." In this respect, is not entirely wrong in saying that I should have used it here as well. I did not do so because the term formally only fits when there is a development plan.

However, there are also areas where there is no development plan. Then §34 regulates what you have to orient yourself by. In such cases, you are not always as free as you might wish: even here the municipality can require that you "nestle" against imaginary lines between existing buildings (comparable to a building line) or at least do not cross them (comparable to a building boundary).

Based on accustomed conventions—which can vary elsewhere—I assume that the cited text excerpt is only relevant for side distances and thus does not help regarding the distance to the front street.

I hope I have now expressed it more clearly :-)
