CMDA FSI rules for buildings in Chennai

Due to the sheer number of construction and development projects being carried out simultaneously, often the deciding factor for the question “Which project is better?” is dependent on whether these projects meet Chennai Metropolitan Development Authority (CMDA) guidelines. Though the CMDA guidelines for developmental projects are quite extensive, let us look into one of the most important highlights that buildings should meet in order to receive CMDA approval.

The rules laid down by the CMDA divide buildings into three types, ordinary buildings, special buildings and multi-storeyed buildings. This classification is based on the height of the buildings, number of households in a plot and extent of commercial activity. The ‘ordinary’ buildings are the buildings that do not exceed a height of 9 m (30’) in height. These are generally low ground plus one-storeyed building. The ‘special buildings’ cannot exceed a height of 15 m (50’). These are generally residential or commercial buildings with more than two floors but not more than 4 floors. The ‘special buildings’ are, as the name suggests, a special type of multi-storeyed buildings. These consist of residential buildings with more than four dwelling units and commercial buildings exceeding 300 meter square (3228 sq. ft.) of plinth area.  When it comes to these buildings, the height of 15 m matters more than the use to which they are put, be it residential or commercial.

However, most of the buildings, nowadays, fall under the ‘special category’ section and hence, this is the topic we will take forward here.

The Floor Space Index (FSI), also known as Floor Area Ratio (FAR), Floor Space Ratio (FSR) and Plot Ratio, is the index by which the total constructible area can be calculated.  This index is used by the authorities to control the density of development.

Constructible area = Land Area * FSI Index

The FSI for ordinary and special buildings (residential and commercial) is 1.5. This means that the plinth area should not exceed 1.5 times the area of the plot where construction is being projected. If the area of the plot where the construction is proposed is 9600 sq.ft, with a 1.5 FSI, the total plinth area is 14,400 sq.ft. However, there are a few exemptions to the this calculation like parking area, electrical transformer room, garbage area, caretaker's room, etc., provided the plinth area of such service areas does not exceed 10% of the total plinth area. Staircase headroom and the lift machine room in the topmost floor are also excluded from this calculation.

FSI can be availed on all plots that abut on a road that has a minimum width of 30 feet. The premium FSI for plots that meet roads that have a width of 30 feet or more and lesser than 40 feet is 20% of the normal FSI. The buildings on plots that abut roads that have a width more than 40 feet and lesser than 60 feet, have a premium FSI of 30% and the plots that abut a road with a width of 60 feet or more have a premium  FSI of 40%. However, premium FSIs are allowed for specific regions only and are also accompanied by additional premium fees.

Hello Ram,

I am assuming that you plan to build a residential flat or something here. Please let me know whether I am right. Also, could you please give me the exact information on the width of the abutting roads and the frontage.

Regarding the new proposal, it doesn't look like it will be approved. There are some strong questions against the proposal to which no answers have yet been given.

Thanks and Regards,
Krish

Hello Krishna, Very interesting article on F.S.I, Thank you. I would like to ask couple of clarifications if I may.
Property is approx 3600 sq feet(40'x90')located on 11th Main Road Anna Nagar. A corner plot 90'facing 11th Main Rd. I believe there is a proposal to offer increased FSI for properties located within 1/2 km of Metro rail station.
1. Any thougts on the FSI based on the current FSI regulations.
2. Your views on the chances of raising the FSI due to Metro rail.
Thank you again for your input.

Hello Ramakrishnan,

I personally think you should be able to use your industrial plot in SIPCOT for building a corporate office/Finance company. Based on DTCP rules, all industrial zones can be used for some pre-determined commercial activities. Business offices and other commercial and financial institutions fall under these activities. However, this is assuming that your land falls under industrial use zone 3 or commercial use zone 2 and not under use zones 4,5,6 or 1. Since I am not sure of the exact location of this property, I cannot confidently determine the use zone it falls within. It would be great if you could let me know the DTCP use zone this property falls under.

Please find below detailed possible uses of a use-zone based on DTCP outline.
http://www.indiarealestateforums.com/forum/chennai/773-dtcp-use-zone-classification

Also, this is just the possible use for the land. You would have to go ahead and get building plan approvals and approval from other departments to divert resources to your building. If you need any further information, then please provide relevant details.

Thanks and Regards,
Krish

Hello Subramanian,

The FSI that you would be able to getg would be around 1.5 for a G+1 unit. SInce the road is below 40 ft width, you cannot get the premium FSI for this plot.

Please let me know if you have any further questions/doubts.

Thanks and Regards,
Krish

Quoting Subramanian:
I have some requirements reg. independent house construction in Chennai. Plot size is 4770 sq.ft. But the shape is like a quadrilateral having front 50ft, back 37 ft. and other two sides left and right are 124 ft and 106 ft. If I try for an uniform close to rectangle size I can get around 3850 sq.ft. with front 50ft and rear 37 ft.

If I go only for ground and First floor what is your suggestion. Definitely not Flat type.

Approximately could you suggest cost of construction also

I need some advise reg. plan to build a new house on a plot size of 4775 sq.ft. in Chennai. The plot is like a quadrilateral of front 50ft, rear 37 ft, left and right sides 124 ft & 106 ft. If I use the geomery for some parallelogram type, may be I could get only 3840 sq.ft usable land. But I am interested in individual house type with Ground and FF. Can you suggest as per FSI how much is allowed.( Road width is 30ft only I think. )
