Yes, that's true. Our house, where it is being built and the fact that the ridge runs north-south and not west-east, did not suit the mayor and the building department at all. We have never had that, don’t know it, don’t want it. Coupled with an almost unbelievable inability to read plans, this constellation ultimately cost us two years and ended with a clear statement from the district administration office that the building must be approved as is.
This letter from the district administration office is ultimately a verbal slap for the mayor and the building department; we read it with great pleasure and joy.
My advice: I would still try to get the municipality on board, because it is simply better to reach an agreement with them. If that is not possible, always clarify with the higher building authority what is allowed and what is not, and if necessary, also challenge the municipal decision. If you adhere to the usual building regulations, you have a good chance.
In the municipal council, decisions are usually made according to the will of the mayor. We witnessed this live: here is a building application that cannot be approved like this! (direct quote from the mayor)
What was not true, but since the mayor had already indicated how the decision should be made, the obedient building department gave the willing votes.
In the end, we found a capable architect whom we knew could work well with the district administration office. This proved true. We even got approval for an overlap of setback areas and were able to set the house back a bit. The reason was that all affected parties benefited from this, especially the neighbors, from whom we thus "steal" significantly less evening sun.
The next instance for us would have been the administrative court; after the building department rejected the application already approved by the district administration office again (for which a special building department meeting was even convened!), the district administration office wrote the aforementioned "slap letter" and as the superior building authority approved the building application. Now the building department could only have filed a lawsuit at the administrative court. They usually don’t do this because the administrative court mostly follows the directives of the higher building authority.
So my advice: grow a thick skin and fight back!
