In central Europe this is often done to bypass a Historic Bureau. Target of those guys is to preserve current "genus loci" of the city forcing owners to use traditional materials and processes to fix the building so outside it is still looking the same.

The loophole is that if building is too damaged, that there is no viable way to repair it, then it can be destroyed and new one can be built. So you can just let it be as is and wait you can help the decay by removing roof and let rain and cold do the work. Or in most extreme cases, just set it on fire "by accident".
