Mumbai DCPR 2034: FSI, open spaces & plot feasibility guide

FSI by zone, area and road width

Reg 30 Table 12 (pp126–127) gives FSI for residential, commercial and industrial zones, separately for the Island City and for the Suburbs and extended suburbs, by road width. It splits FSI into basic, premium and TDR parts. Some special areas have a fixed FSI, for example 0.75 for the BARC-earmarked area in M Ward and 0.5 for Akse, Marve and CRZ-affected Erangal (Table 12 II, p127).

Open spaces, not coverage

DCPR 2034 has no general ground-coverage cap. The footprint is limited by the open spaces required around the building. The calculator treats every face as a light and ventilation face under Reg 41(2) and adds both buildings’ open spaces between two buildings (Reg 41(1)(a), p288). A plot is treated as fronting on every road (Reg 2, p52).

Redevelopment schemes are not calculated

FSI under Regulations 33(7), 33(9), 33(10) and 33(12)(B) depends on rehabilitation entitlements, incentive ratios and scheme approvals, not on a plot table. The calculator does not substitute Table 12 figures for these schemes; they need a scheme-specific calculation.

Stilt and height

No stilt height limit was found in DCPR 2034. Reg 37(30) (p278) limits parking floors above the stilt to 2.4 m below the beam; the calculator names that clause but does not apply it to the stilt. Height is measured from the average ground level around the building to the topmost terrace (Reg 2(73), p52).

What to confirm before relying on a Mumbai study

Confirm the zone and the road width in the development plan, any CRZ, heritage, airport-height or other overlay, and later modifications to DCPR 2034. Small plots of 21–250 m² have their own open-space table (Reg 41(3)); the calculator uses the general values.
