Mumbai’s old housing redevelopment segment recorded strong growth in 2025, expanding by 16% year-on-year, driven by a steady rise in redevelopment activity across the city, according to data from Knight Frank India. The momentum has carried into 2026, indicating continued developer and society participation in rebuilding ageing housing stock.
The data shows that 229 development agreements (DAs) were signed in 2025 for the redevelopment of old residential buildings, up from 196 agreements in 2024. Between January 2020 and March 15, 2026, a total of 1,094 redevelopment agreements have been executed, unlocking approximately 432 acres of land for redevelopment across Mumbai.
Activity has been most concentrated in the western suburbs, which accounted for the majority share of redevelopment deals. Of the total 1,094 agreements, 773 were signed in western Mumbai, unlocking 321.2 acres of land. The central suburbs followed with 261 agreements covering 85.9 acres, while Central Mumbai recorded 38 agreements accounting for 38 acres. South Mumbai saw 22 agreements, unlocking 8.3 acres.
Among micro-markets, Borivali emerged as the leading redevelopment hotspot, contributing 217 agreements—around 20% of the total—unlocking 90.4 acres of land. Andheri followed with 115 agreements covering 74.8 acres. Bandra recorded 74 agreements unlocking 24.4 acres, while Malad saw 67 agreements contributing 26.6 acres. Ghatkopar ranked fifth with 59 agreements, covering 14.1 acres.
The report estimates that nearly 1,100 redevelopment agreements signed over the past six years will collectively generate around 59,000 new housing units. Of these, more than 45,000 units are expected in the western suburbs, over 11,800 in the central suburbs, 1,600 in Central Mumbai, and 731 in South Mumbai.
Knight Frank India noted that this unit estimate is derived from Floor Space Index (FSI) calculations for saleable area, excluding rehabilitation and amenity components. It also clarified that the projections reflect supply potential and do not account for factors such as project phasing, financing constraints, or actual launch timelines.
Overall, the data underscores Mumbai’s increasing dependence on redevelopment-led growth, especially in densely populated suburban pockets where fresh land availability remains extremely limited.
