In order to ensure a high-quality residential housing management and maintenance process, it is important to first accurately define the concept of real estate and understand how the technical condition of the building affects the real estate management process. It is necessary to compare this understanding and conclusions from the assessment of the technical condition carried out in Riga and Pieriga regarding multi-apartment residential buildings with the situation in Bochum, Germany. The authors of the research have presented statistical data regarding the number of buildings in Latvia and Germany during the last five years. In Latvia, the Construction Information System has been implemented, which includes not only the register of building tradesmen, but also the register of residential house managers, the question arises as to whether the manager must necessarily register in this system and how exactly the professional competences of the manager differ from the professional competences of the “house manager” competencies. Several similar systems and platforms for construction information management operate in Germany. Germany is a large country with many regions, and different federal states and cities may have their own systems and data management methods for the construction industry. These systems are used to facilitate construction project monitoring, permitting, and general construction data management. The aim of the research is to study and compare the management processes of multi-apartment residential buildings, the processes of managing multi-apartment residential buildings in Pieriga, Latvia and Bochum, Germany, respecting the professional competences required for the activity of a real estate manager.
