“Subdivision” is a program that manages the mechanism of sorting real estate units technically and legally through (the system of ownership, sorting, and management of real estate units) which contributes to determining the unit’s square meter and the rights of every unit in apartment buildings and real estate compounds. Additionally, the program determines the boundaries of common and public areas to enhance landlords’ relations and facilitate the necessary services and procedures, preserve real estate assets, and foster safe residential environments to sustain the real estate sector.
