The premium FSI, based on the government order, is capped at 1 and is based on the width of the road leading to the apartment. The amount to be paid by for the additional FSI will be proportional to the cost of the additional extent of land gained based on the guideline value of registration.The applicant needs to remit the fee for premium FSI before getting permission from planning committee.
However, premium FSI is not allowed in the red hill catchment areas which is restricted for development and those water bodies that are maintained by Chennai Metropolitan Water supply and Sewerage Board which are restricted for drinking water purposes. Additionally, the person availing premium FSI will also be able to get increased land extent for construction of building.
For example, in case the normal permissible or allowed FSI is 1.50 for a particular area, then for an increase of 1 square meter, proportional area of 0.66 m (2/3) will be required. Similarly, in case of those plots that have a normally allowed FSI of 2.0 or 2.5, every additional increase of 1 square meter will require a proportionate land of 0.50 sq.m. (1/2) to 0.40 sq.m.(2/5), respectively.
