I own a plot of land in Chennai and wish to construct a bungalow for my personal stay. I wish to construct on my own. Would it be possible to let me know what are the governmental permissions I should obtain to construct?

If the bungalow will be two stories or less (G+1 or S+2), then you will need building approval from your local municipal corporation. If you wish to construct more number of floors, you will require a CMDA building approval.
I wish to buy a flat in Chennai within CMDA limit, particularly around Chrompet, East Tambaram.
I presume that the layouts for building flats should be approved by CMDA/DTCP and in case of older settlements, after demolishing the old houses. When approached, most of the builders say that CMDA approval for flat construction is not necessary for a stilt + one or two floors and for this local town or panchayat union approval is enough. Please clarify:
1) The CMDA limit of Chennai
2) Whether local town/Panchayat union approval is enough for flats (within CMDA) with stilt+two floors
3) What are the set-backs required on all four sides
4) The floor space indices [FSI] norms

1) CMDA limits are too numerous to enlist and change periodically. Please refer to the CMDA web-site for the latest limits.
2) A local corporation approval is adequate if the number of floors is two (G+1 or S+2) or less AND the number of flats in the building is no more than 6.
3) Set-backs depend on the width of the road on which the property lies. The minimum front setback is 1.5m and increases in steps up to 6m based on the road width.
The rear setback required is 1.5m. Side setbacks range from 1m on one side to 1.5m on both sides based on the road width.
Set-backs requirements are less for continuous building areas and plots designated for economically weaker sections of society.
4) FSI: 1.5 and plot coverage should generally not exceed 70%.
