Building permit from 1931 not adhered to

I wouldn't do anything at first and would just rent it out, period.

It is new to me that demolitions need to be approved by the building authority.


... inside the building area, the authority has nothing to do with it.

I don't know about the rest, how it is with renting.
If you think that the static structure is questionable, you are acting negligently when renting.

That also applies to you!

Oops. Hopefully no one from your building authority is reading along or hopefully you haven’t demolished anything yet.

It depends on what was remodeled. Structural interventions, even inside the house, do require approval.

I did not write anything about a cancellation !!

that an approximately 3 m extension on the right side of the house was not present. However, this extension was built at the same time by the then masonry company, as is clearly visible in old photos.

I did not write anything about a demolition!!
