Mumbai Redevelopment Boom Continues Into 2026

Mumbai’s real estate rehabilitation market gained 16% in 2025 over the previous year, owing to an increase in redevelopment deals around the city. According to Knight Frank India, a total of 229 development agreements (DAs) for the renovation of ancient structures were signed in 2025, up from 196 the previous year.

The enthusiasm carried over into 2026, with roughly 30%, or 70, of the total redevelopment agreements for 2025 inked in the first 74 days of the year, up to March 15, according to the data.

Total of 1,094 DAs signed in the last 6 years

According to Knight Frank India data, 1,094 DAs have been signed during the last six years, from January 2020 to March 15, 2026. The signature of these 1,094 redevelopment accords has made 432 acres of land available for redevelopment.

Western suburbs have the biggest amount of redevelopment transactions.

The western suburbs of Mumbai’s real estate market have signed the most redevelopment agreements during the last six years. According to the data, 773 of the 1,094 DAs signed were in the western suburbs, unlocking 321.2 acres of land, followed by 261 in the central suburbs, unlocking 85.9 acres of land, 38 in Central Mumbai, unlocking 38 acres of land, and 22 in South Mumbai, unlocking 8.3 acres of land.

Borivali leads with 20% of the total redevelopment deals

Out of the total 1,094 DAs signed, Borivali in Mumbai’s western suburbs had the most (217), unlocking 90.4 acres of land, followed by Andheri (115), unlocking 74.8 acres.

Bandra had the third-highest number of 74 DAs signed, unlocking 24.4 acres of land, followed by Malad with 67 DAs signed, unlocking 26.6 acres of land, and Ghatkopar with the fifth-highest number of 59 DAs signed, unlocking 14.1 acres of land for redevelopment.

Old building redevelopment to add 59,000 units

According to the data, the signing of about 1,100 DAs has resulted in the creation of 59,000 housing units, with over 45,000 to be developed in the western suburbs, over 11,800 in the central suburbs, over 1,600 in Central Mumbai, and 731 in South Mumbai.

Knight Frank India did a unit generation analysis using the Floor Space Index (FSI) for sale areas; rehab and amenity spaces were excluded. The data show that the unit generation estimate is primarily dependent on supply and does not account for launch velocity, funding, or phasing constraints.

According to the research, the redevelopment projects will create 1.5 lakh housing units and produce ₹9,115 crore in stamp duty revenue for the state government.

FSI norms for redevelopment

According to Knight Frank India, most societal redevelopment projects are now being carried out under the Development Control Regulation (DCR) 33(9), 33(11), and 33(20b). These laws set the maximum Floor Space Index (FSI) for redevelopment. The available FSI is determined by the width of the road adjoining the housing society.
