Signature for the neighbor's construction project

I would be cautious about signing something if my signature is not necessary. What do I get out of it? Or will the neighbor pay for an architect and lawyer to review and evaluate the documents?

In my opinion, this also has nothing to do with "endangering contact" or "being stubborn."

I would apply the same to myself as well.

You don’t have to assume the worst right away. It is quite possible that the neighbor’s plan only deviates slightly from the development plan and does not affect the OP at all. For example, if a dormer is desired or a higher retaining wall is necessary due to the intended terrain shaping, or whatever else.

First, take a look and have the neighbor explain it. You should then be able to quickly assess whether it causes any disadvantage for you/your property or not. If not, just sign and start positively into the new neighborhood.

From my own experience, I can only say that unjustified refusal to sign can indeed be annoying.

Edit: was faster ;)

Or the topic of roof pitch. We have 30-45 degrees, all the people building bungalows only make it 20 degrees steep so that the attic does not become higher than the ground floor.

Thank you for your answers. Are deviations from the development plan to be clearly marked? Example: The neighbor's house is only 2m from the boundary. I sign as a layman. Later, when submitting my own building application, I find out that I myself am not allowed to build 3m from the boundary because I unknowingly adopted 1m of setback areas.

Thank you for your answers. Are deviations from the development plan required to be clearly marked? Example: The neighbor’s house is only 2m away from the boundary. As a layperson, I sign off. Later, when submitting my own building application, I find out that I am not allowed to build closer than 3m to the boundary, since I unknowingly adopted a 1m distance area.

Deviations are not marked, but there must be a written statement and justification for the deviation at the front of the building application folder. You can also request to see this in addition to the plan.

You don't always have to bring out the heavy artillery or paint the devil on the wall.

Sorry, maybe I'm biased, but in my professional environment, contractual regulations serve almost exclusively for the worse case...

And defending my rights wouldn't be described as "heavy artillery" or "worst case" by me. I read everywhere that the effects of a neighbor's signature should not be underestimated...

Presumably, it is only about notifying the neighbors, which would otherwise be obtained in writing by the office and would cost extra time and money. As long as the project complies with the development plan, the signature does not matter to my knowledge. The neighbor is only informed.
