Dear forum,

an old house is being renovated and given a new extension (developer contract). The roof remains as is. According to the developer, the roof has been inspected and should last at least another 10 years. The new owners' association is not so sure about that.

Now the community is asking what the building authority has to approve in the case of a former single-family house, now divided into several condominiums with the conversion of the attic.

Do they also check the old building, if the attic is now completely used as an apartment, whether it is durable?

Hello,


Developer contract definitely not; you are simply building with a general contractor.

If your provider gives you the statement in writing, you can disregard it. However, I estimate that he will refuse to do so. Order a roofer and ask him to inspect the existing structure, then you will be on the safe side. However, this will cost some money; no one gives away anything for free.


A building application to obtain a building permit does not necessarily have to include static calculations. The building permit is granted without submitting the static calculations; these must be presented to the building authority at the start of construction. So yes, the building authority will certainly want to be convinced of the structural stability, among other things.

Rhenish regards
