Mumbai's Redevelopment Boom: 388 Buildings, One Big Opportunity

South Mumbai is on the cusp of one of its biggest housing transformations in decades. After years of false starts, the Maharashtra Housing and Area Development Authority (MHADA) has agreed to directly undertake the redevelopment of 388 old and dilapidated buildings spread across prime southern neighbourhoods, a decision that could unlock housing for tens of thousands of families and free up valuable land for new supply.

These 388 structures are not ordinary buildings. Most of them were last reconstructed by MHADA three to four decades ago, replacing nearly 900 old structures at the time. They are located across key southern neighbourhoods such as Colaba, Girgaon, Mumbadevi, Byculla, Sewri, Prabhadevi and Mahim, each typically containing 80 to 100 compact flats measuring between 100 and 200 sq ft. Today, they are once again structurally distressed, but their small footprints have made them commercially unattractive to private developers for years.

That's precisely why the redevelopment stalled for so long. Their plot sizes, often between just 400 and 600 sq metres, make them commercially unviable for private developers under current redevelopment norms. MHADA has now stepped in to redevelop these dilapidated South Mumbai buildings after private developers failed due to small plot sizes and resident disagreements, with over 27,000 families expected to benefit.

The breakthrough came through a formal commitment from the state's Self-Redevelopment Authority. The Mhada Sangharsh Kruti Samiti, representing the affected buildings, received written confirmation that MHADA will take up redevelopment if a group of buildings comes together and resolves collectively that MHADA should undertake the project. Eknath Rajapure, working president of the samiti, called it a critical development. He estimated that nearly a third of the buildings could benefit, noting that previous attempts to appoint private developers had failed, and since the land belongs to MHADA, the agency's willingness to take up cluster redevelopment offers crucial relief.

This local push is part of a much larger policy shift. MHADA's leadership has been vocal about moving away from one-building-at-a-time redevelopment toward integrated, large-scale renewal. Nearly 90 per cent of Mumbai's developable land has already been utilised, and MHADA is opening up between 800 and 1,000 acres for cluster redevelopment projects, planned as integrated layouts of 60–100 acres that can support infrastructure, open spaces, transport links and basic services — essentially creating small townships within the city. This aligns with a state-wide housing target. Under Maharashtra's housing strategy, the state aims to build 2.8 million affordable homes in the Mumbai Metropolitan Region by 2030, with MHADA directly contributing around 800,000 units through its schemes and partnerships.

Progress is already visible on the ground. Nearly 50,000 homes have been delivered in the last two-and-a-half years, and MHADA's CEO Sanjeev Jaiswal has said that 60-70 per cent of future housing supply is likely to emerge from approved or prospective cluster projects. He has also flagged why this shift is urgent. Jaiswal remarked that Mumbai's housing affordability index — indicating that the average household commits roughly half its income to home loan equated monthly instalments — points to structural bottlenecks that require systemic interventions.

Not everything is moving smoothly, though. A parallel mechanism meant to help MHADA take over stalled private redevelopment projects has barely worked. More than four years after amendments to the MHADA Act empowered the authority to acquire stalled cessed buildings, not a single project has been fully acquired or progressed, and since Section 91(A) was introduced in July 2021, MHADA's Mumbai Building Repairs & Reconstruction Board issued takeover notices for around 90 stalled projects. It later moved to take over only 14, and eventually just seven projects received state approval. Activists have been sharply critical of the pace. Jeetendra Ghadge, founder of the Young Whistleblowers Foundation, described near-total paralysis in the acquisition system meant to rescue tenants trapped in legal and financial limbo.

For homebuyers and investors, this redevelopment wave matters for a simple reason: land in South Mumbai is scarce, and every cluster project that moves forward adds fresh, modern housing stock in micro-markets like Worli, Prabhadevi, Byculla and Mahim — areas that have traditionally seen little new supply. As MHADA-led and private cluster projects gather pace over the next few years, buyers can expect a mix of rehabilitation housing for existing tenants and new sale inventory in some of Mumbai's most established neighbourhoods, often backed by larger open spaces and better infrastructure than the ageing structures they replace.
