No Office Order number is printed in the supplied text.
The Chennai Metropolitan Development Authority resolved that the Floor Space Index attributable to Open Space Reservation land in a sub-division may be allocated among the individual plots according to their respective extents.
Who is affected
The Chennai Metropolitan Development Authority procedure applies to owners and planning permission applicants for vacant plots in approved sub-divisions. It also applies to vacant plots in sub-divisions approved before the Office Order.

- Floor Space Index cannot be claimed for road area gifted as part of the sub-division.
How permissible Floor Space Index is calculated
For construction on an eligible plot, permissible Floor Space Index is calculated using the extent of the plot covered by the application, together with the plot's proportionate share of the Floor Space Index attributable to the Open Space Reservation extent.
The calculation identifies:
- Te as the total extent of the site.
- Pe as the extent of Open Space Reservation land reserved, or the extent for which equivalent land cost was collected.
- Re as the extent of the road.
- S1 to Sn as the extents of the individual plots, where the number of plots is not more than eight.
- The proportionate Open Space Reservation extent for an individual plot as Pe multiplied by Sn, divided by Te minus Re.
The proportionate Open Space Reservation extent is calculated only for computing Floor Space Index.
