It has been found that the illegal or unauthorized structures in the city have reached to 30,000 and are occupied by families. However, these buildings have occupied the government, wakf and endowment lands. They are even present on the full tank level (FTL) area of the water bodies in the city. As per the Greater Hyderabad Municipal Corporation, there is no permission to construct the illegal buildings, especially apartments and buildings with five floors without the knowledge of the town planning staff. It is, however, found that these applicants could not be declared as owners as the lands belonged to government, endowments or the FTL area.
