An amendment to the state building code, which the Senate has initiated, is also intended to make building easier and faster. According to Geisel, it enables serial construction and simplifies the conversion of attics, for example. In addition, there are specifications, for example, on the barrier-free accessibility of apartments and a ban on the complete boarding up of front gardens. The construction industry, the Association of Berlin-Brandenburg Housing Companies (BBU), and the CDU criticized that the amendment would make building more expensive and more difficult.
