This list of tallest buildings in Chennai ranks high-rise buildings in Chennai, India based on official height.  Unlike other metropolitan cities in the country, Chennai continues to experience a horizontal growth (that is, expanding continuously in its area) rather than a vertical growth by means of building more skyscrapers, owing to the presence of weather radar at the Chennai Port, which prohibits construction of taller buildings beyond its permissible limits.  The maximum permissible building height in Chennai was limited to 40 m until 1998, when it was increased to 60 m.  This restriction continued until the second master plan of the Chennai Metropolitan Development Authority was rolled out in 2008, after which the restriction was lifted.  Until then, the LIC Building at Anna Salai, with 15 floors, dominated the city's skyline.  However, after the big companies started building tall concrete structures in the city since then, the city's skyline started changing, especially along the periphery.  Currently, seven towers of Hiranandani Upscale Egattur are the tallest buildings in Chennai and south india with a maximum height of 204 m .  Still many more high-rises are already under construction in the city and dozens are proposed.  However, the height of the buildings in the central business district have seldom gone beyond 20 floors.  Most of the high rises in Chennai are corporate entities rather than residential ones as found in other South Asian cities.
