A proposal to raise the cap on premium Floor Space Index (FSI) to 5 or higher is still under consideration, with the Chennai Metropolitan Development Authority (CMDA) calling for wider consultations before taking a decision.FSI determines the permissible built-up area on a plot in relation to its size. Premium FSI allows developers to construct beyond the permissible limit by paying an additional charge to the government, subject to planning regulations.
