In recent decades, with the growth of construction and residents in the Serbian capital, the needs for organizing all aspects of residential living in apartment buildings have significantly increased, such as regular maintenance, cost management, and repairs. Previously, these matters were handled by the presidents of the residents' assembly, who were often the owners of the apartments themselves. However, in recent years, this responsibility is increasingly shifting to professional management. Moreover, there is data indicating that over 50% of residential communities in Belgrade engage professional managers.
