Anyone who retrospectively insulates their old building on the property line can use it to protrude a little into the neighbor’s garden. This was decided by the Federal Court of Justice (BGH) on Friday based on a neighborhood dispute in Cologne. However, new buildings would have to be planned in such a way that the thermal insulation remains within the boundaries of your own property. The BGH also made it clear: In the interests of climate protection, countries may regulate subsequent thermal insulation with their own regulations (Az. V ZR 115/20). Energy-efficient building renovation should save energy, which is in the general interest. In Cologne, neighbors had quarreled about the planned external insulation of an apartment building that was right on the property line.
