Additional costs after building the house

Also art is being tested. Additionally, wall coverings, carpets, etc. Couldn't believe it either... At least in BW. For us, it will anyway be a discussion about what counts as living space and what does not... Let's wait and see.

Sorry, if off-topic: How is it with the property tax in our case, since we are only renovating? Will there be a new inquiry at some point? But we are not doing anything with a building application or anything, so actually no one from the authorities knows what is happening here.

Do not wake sleeping dogs. Normally nothing. When the new regulation comes, it will always be adjusted according to age, etc.

Where there is no plaintiff there is no judge
I have never heard of anyone having to pay more property tax after a renovation

The forms are standardized for West Germany. THERE IS no query about art, how do you come up with that? As I said, wall coverings and floor coverings as equipment features are logical, but they are not art objects. Let's be frank, I handle such declarations daily, so I would say I have a certain basic knowledge. What counts as living space and what does not is also clearly regulated, so there really shouldn't be any discussions.

That can happen, but actually only if a building application has to be submitted for the measures and if the renovation measures are significant enough. The limits up to the value update are quite high.
