Floor Area Ratio is the total built floor area permitted on a plot, as a multiple of the plot itself. These are the rules that set it, and the ones that decide what does not count towards it.
Basic FSI — the floor space allowed without paying a premium or loading TDR — is 1.10 for every road width band, from a lane under 9 m to a 30 m arterial. The width of the road does not change what you start with; it changes how much more you are allowed to buy or load on top.
UDCPR Regulation 6.3, Table 6-G column 3 — and 13 related rules below.

| Base FAR | 1.1 |
1.10 — the basic FSI and nothing more. Below 9 m no premium FSI and no TDR loading are available, in a Municipal Corporation or anywhere else. A narrow approach road is the single hardest cap in these regulations.
| Road width up to (m) | 9 |
| Base FAR | 1.1 |
Up to 2.00 in all Municipal Corporations and in CIDCO as Planning Authority: basic 1.10, plus up to 0.50 premium FSI on payment, plus up to 0.40 TDR loading.
| Road width from (m) | 9 |
| Road width up to (m) | 12 |
| Base FAR | 1.1 |
| Premium FAR (max) | 0.9 |
Up to 1.70 outside the Municipal Corporations: basic 1.10, plus up to 0.30 premium FSI, plus up to 0.30 TDR. The same plot on the same road gets 0.30 less than it would inside a Corporation.

| Road width up to (m) | 12 |

Up to 3.00, the highest in the table: basic 1.10, up to 0.50 premium FSI, up to 1.40 TDR. Nearly two thirds of the buildable area on the widest roads is bought or loaded rather than granted.
| Road width from (m) | 30 |
| Base FAR | 1.1 |
| Premium FAR (max) | 1.9 |
Up to 2.50: basic 1.10, up to 0.30 premium FSI, up to 1.10 TDR.

A further ancillary area FSI of up to 60% of the FSI proposed in the development permission is allowed on payment of premium, and up to 80% for non-residential use. It sits above basic, premium and TDR, and applies to all buildings in all zones.
The TDR column does not apply in areas with no Planning Authority; the maximum building potential is reduced accordingly.
