You can also race through the city at 200, no one cares as long as you don't get checked. There are legal obligations. Period. Whether they are enforced or not is another matter.
You don't have to do more than insulation of the top floor ceiling or roof as well as insulation of water pipes or heating pipes in unheated rooms (if exposed) in the first two years after purchase.
Heating replacement depends on the heating system. Very old oil heating that is not condensing technology should also be replaced (around the 80s or older). Ask the chimney sweep about that.
There is no central heating..
And the chimney sweep has been here several times and has seen everything..
Basically, I wanted to know whether this law applies to me. Because we are already considering moving out..
Yeah, just the floor ceiling and pipes. Both are also sensible, cheap, and quick to do. The insulation of the floor ceiling pays off within a few years if you do it yourself. The roof is definitely not from 1932, at least not the covering.

My main concern was whether this law applies to me. Because we are already considering moving out..
This is a law that, as far as I know, applies nationwide. So, of course, it also applies to you. Unfortunately, you do not answer the other questions.
