All types of construction need to comply with building regulations. You need to deal with building regulations when constructing a new building, expanding existing workspace, or modifying rooms within a building. However, these regulations may also come into play when merely renting or leasing premises for a new business, depending on the intended use.
In Munich the Local Building Commission (LBK) in the Department of Urban Planning and Building Regulation functions as a building supervisory (sub-)authority. The LBK can give you advice on building law and the necessary documentation before you submit an application. The advisory center at Blumenstraße 19 offers advice by phone, email or in person.
