Berlin's Environmental Protection Zones: What Apartment Owners Need to Know

There are now ten social preservation zones in Berlin’s Tempelhof-Schöneberg district. As of 2026, Berlin will thus have a total of 82 social preservation zones. The basis for neighborhood preservation is Section 172 of the Building Code (BauGB). The goal is to maintain the composition of the local resident population and protect it from displacement caused by urban redevelopment and rising housing costs. At the same time, the established structures of the affected neighborhoods are to be preserved. The districts determine which areas are classified as particularly in need of protection based on relevant studies. Since April 2026, uniform administrative regulations have also been in effect throughout Berlin for the approval of construction projects in social preservation zones.

It is important for apartment owners to understand that strict regulations apply in neighborhood preservation zones, particularly with regard to modernization and renovation projects. The ban on so-called “luxury renovations” is intended to prevent rents from reaching levels that residents can no longer afford, which would cause them to leave the area. The municipality or district may also specify which measures the ban covers. These typically include combining two small apartments into one large one or adding an additional balcony. In neighborhood preservation zones, it is also often not permitted to add a second bathroom or install underfloor heating.

That said, renovations are not generally prohibited; however, they must be approved by the building authority. All measures necessary for “bringing the property up to contemporary standards” (§172 BauGB) are permitted. These include, for example, repairing broken water pipes, installing central heating, or replacing single-pane windows with double-pane windows. Energy-efficiency renovations in accordance with the Energy Conservation Ordinance are generally not subject to the ban either; on the contrary, they are often eligible for substantial subsidies —since they frequently bring the apartment up to contemporary standards.

Anyone who has recently purchased a condominium and would like to modernize it should therefore find out whether their unit is located in a neighborhood preservation zone and, if so, whether they need a permit for the modernization. Anyone planning to purchase a condominium should check in advance whether there are any neighborhood preservation zones in the city of their choice—and, if so, where they are located. Hamburg has designated several neighborhood preservation zones, including in Eimsbüttel-Nord and the southern part of Neustadt. In the German capital, there are neighborhood preservation zones in the following districts: Berlin Mitte, Tempelhof-Schöneberg, Friedrichshain-Kreuzberg, and Pankow.
