What a commercial fit-out costs
Commercial rates sit well above residential because of specification, not finish. Fire systems, HVAC extension, structured cabling, access control and landlord-mandated vendors all sit inside a fit-out scope and none of them appear in a home:
| Building grade | Mumbai rate per sq ft | What it covers | Programme |
|---|---|---|---|
| Grade-B / suburban | ₹1,220 – ₹1,840 | Partitions, ceilings, basic MEP extension, workstations | 6 – 10 weeks |
| Grade-A / business park | ₹2,130 – ₹3,190 | Landlord-spec services, mandated vendors, full MEP | 10 – 14 weeks |
| BKC / prime CBD | ₹2,560 – ₹3,840 | Full Cat B, night working, landlord supervision charges | 12 – 18 weeks |
Excluding 18% GST, loose furniture and IT hardware. These are our own rates, taken from Mumbai commercial fit-outs Greenbox has billed and completed and held at October 2026 prices. See Mumbai office cost per sq ft for the breakdown.
The three things that decide a commercial programme
- The landlord's fit-out manualRead it before designing, not after. It sets ceiling voids, permitted working hours, mandated vendors for fire and HVAC, and the deposit. Grade-A buildings enforce it, and a design that ignores it gets rejected at drawing approval.
- Whether the space is occupiedAn occupied fit-out is phased work at a premium, usually with night and weekend shifts. It costs more per sq ft and takes longer, but no business days are lost.
- The shell you are starting fromBare shell, warm shell and Cat A handovers include very different amounts. What the landlord has already provided can move the fit-out cost by 30% either way.
