Mumbai redevelopment in 2026 has passed an inflection point: over 1,000 projects since 2020 and about 15% of housing sales. What the JLL-NAREDCO figures mean for residents, and for the finishing phase.
Mumbai redevelopment in 2026 is no longer a side-stream of the housing market. On 3 September 2026, JLL and NAREDCO Maharashtra released a report titled 'Redevelopment in Mumbai: The Inflection Point', at NAREDCO Maharashtra's Real Estate and Infrastructure Investors' Summit. As reported by the Free Press Journal and Outlook Money, it counts more than 1,000 redevelopment projects launched in the city since 2020, and puts redeveloped homes at around 15 per cent of Mumbai's housing sales across 2025 and the first half of 2026, up from roughly 6 per cent between 2016 and 2021. This article explains what those figures actually say, what they mean if you live in an old building, and why the phase of a redevelopment that residents feel most, the finishing, deserves more attention than it usually gets.
It is written by Chamunda Constructions, a civil and finishing contractor based in Kandivali West since 2004 and led by its founder Bhadresh Chavda. We are not a developer and we do not broker redevelopment deals. We carry out the finishing work that turns a newly cast structure into homes people can move back into, and we have done that on redevelopment and Slum Rehabilitation Authority schemes in the western suburbs. The report's numbers are the report's; the reading of what they mean on site is ours.
Mumbai redevelopment in 2026: the headline numbers
The report was prepared jointly by JLL and NAREDCO Maharashtra. The figures below are as published in coverage of its release by the Free Press Journal on 3 September 2026 and Outlook Money on 15 September 2026. We have not reproduced the full report, and anyone making a decision on the strength of these numbers should read the original.
- More than 1,000 redevelopment projects launched in Mumbai since 2020.
- Redevelopment projects launched since 2020 account for around 13 per cent of Mumbai's overall residential supply.
- Redeveloped homes made up around 15 per cent of housing sales in 2025 and the first half of 2026, compared with about 6 per cent in 2016 to 2021.
- Around 13,500 cessed buildings in Mumbai are described as requiring replacement.
- The Western Suburbs hold 22.4 per cent of the city's ageing stock, and South Mumbai 14.2 per cent.
- Borivali, Malad, Andheri, Vikhroli and Goregaon are named as the top five redevelopment locations, together accounting for about 36 per cent of projects, according to the Free Press Journal's account.
- The report counts 1,202 active slum rehabilitation projects covering 3,21,858 hutments across 2,156 acres, which it describes as nearly four times the acreage completed in the 30 years since the Slum Rehabilitation Authority was formed in 1995.
- More than 1,600 self-redevelopment proposals, where the residents' society itself acts as developer, are cited as being in the pipeline.
Two quotations from the launch sum up the tone. NAREDCO Maharashtra president Kamlesh Thakur described redevelopment as having evolved from a policy initiative into the primary engine of the city's housing supply. JLL's Karan Singh Sodi framed the question as how quickly the transformation can be executed safely, rather than whether redevelopment will dominate supply.
What 'inflection point' actually means
An inflection point is where a curve changes direction. The report's argument is that redevelopment has moved from something that happened building by building, whenever a society and a developer found each other, to the main mechanism by which new homes are added to the city. The key signal is the comparison between supply and sales. Redevelopment makes up roughly 13 per cent of supply but around 15 per cent of sales, which means buyers are absorbing redeveloped homes faster than their share of launches would suggest.
For a resident, the practical translation is simpler. If you live in an old building in the western suburbs, it is increasingly likely that your society has already been approached, is discussing redevelopment, or will be soon. The market that used to need convincing is now looking for buildings.
Why redevelopment is where the housing comes from
The underlying reason is land. In February 2026, MHADA vice-president and CEO Sanjeev Jaiswal said at an ET Realty conclave, as reported by Outlook Money, that nearly 90 per cent of Mumbai's developable land has already been used. When there is almost no vacant land left, the only way to add homes is to replace low-rise, under-used buildings with taller ones that use the floor space index the development rules now allow.
That is also why redevelopment clusters where it does. Old buildings of three and four storeys, built decades ago under older rules, sit on plots that can now carry far more floor area. The gap between what stands and what could stand is what pays for a redevelopment: the new sale flats fund the construction of the residents' replacement homes.
Why the western suburbs lead
Four of the five top redevelopment locations named in the report's coverage, Borivali, Malad, Andheri and Goregaon, are on the western line, and the Western Suburbs hold the largest single share of ageing stock. Much of Kandivali, Borivali and Malad was built out in the 1970s and 1980s as co-operative housing, and a large number of those buildings are now past the age at which structural concerns and repair costs start to dominate society meetings.
Infrastructure adds to the pull. Outlook Money's coverage of the report lists Metro line expansion, the Coastal Road, the Borivali-Thane twin tunnel and the Goregaon-Mulund Link Road as catalysts that will shape where redevelopment goes next. Better connectivity raises the value of the sale component, which improves what a developer can offer the existing residents.
This is our home ground. Chamunda Constructions is based in Kandivali West, and our published projects include Tower 28, the sale component of the Navjeevan SRA redevelopment in Malad East, and the ongoing Siddhivinayak SRA scheme on New Link Road in Kandivali West. When we say the western suburbs are where redevelopment is concentrated, we are describing the sites we walk every week.
What the numbers mean if you live in an old building
Statistics about the market do not tell a resident what to do. They do change the context in which your society makes its decisions, and there are four things worth taking from them.
- You have more options than societies had a decade ago. Builder-led redevelopment, self-redevelopment and, for some areas, cluster redevelopment are all live routes, and each has different risks.
- Your building's age matters legally as well as practically. Under Section 353B of the Mumbai Municipal Corporation Act, buildings more than 30 years old must be inspected by a structural engineer registered with the BMC, with a structural stability certificate submitted and renewed every ten years.
- Competition among developers is real, but so is the risk of a rushed decision. More offers do not automatically mean better terms.
- The quality of the new home is decided in the agreement, not at possession. The period when residents have leverage is before they sign.
None of this is legal advice. Redevelopment in Maharashtra is governed by several overlapping frameworks, including the development control regulations, the co-operative societies law and its rules, government directives on redevelopment, and MahaRERA for the sale component. A society should take independent legal and technical advice before committing to any route.
The three routes to redevelopment
Most coverage of redevelopment treats it as one thing. For a resident, it is at least three, and they differ mainly in who carries the risk.
Builder-led redevelopment is the familiar route. The society appoints a developer, who pays for the construction, provides rent or transit accommodation during the works, builds the residents' new flats and recovers the cost by selling additional flats. The developer carries the construction and market risk; the society carries the risk of having chosen the wrong developer.
Self-redevelopment puts the society in the developer's seat. The society raises the finance, appoints a project management consultant and contractors, and keeps the surplus that a developer would otherwise earn. Maharashtra has supported the route since a Government Resolution of 13 September 2019, and in October 2025 the state set up a Self-Redevelopment Authority chaired by Pravin Darekar. We cover it in detail in our guide to self-redevelopment for Mumbai societies.
Cluster redevelopment groups many buildings or a whole colony into one larger scheme, planned as a layout with roads, open space and amenities. It is the route MHADA has been pushing for its older colonies, and in June 2026 MHADA declared the highest bidders for three large colony clusters. Our explainer on cluster versus standalone redevelopment sets out how it differs for residents.
Where the redevelopment timeline actually goes
Residents tend to picture a redevelopment as demolition, a tower going up and then keys. The reality has more phases, and the one that matters most for daily life comes late.
- Feasibility and decision: structural condition, the plot's development potential under the regulations and a feasibility report, usually prepared by a project management consultant.
- Developer or contractor selection: tendering, comparison of offers and the society's general body decision.
- Agreements: the development agreement and the permanent alternate accommodation agreement for each member.
- Approvals: the building permissions, the IOD and the commencement certificate from the planning authority.
- Vacating and demolition: members shift to rented or transit accommodation.
- Structure: foundations, podium, and the RCC frame floor by floor.
- Finishing: waterproofing, plumbing, electrical, tiling, kitchens, bathrooms, windows, lobbies, staircases and snagging.
- Occupation: the occupancy certificate and handover of the new flats.
On a typical mid-rise residential building, finishing takes as long as the structure did, and sometimes longer. It is also the phase that runs while members are still paying rent elsewhere, which makes it the phase most exposed to schedule pressure. Our earlier society redevelopment finishing checklist covers the specification side of that in detail.
Why the finishing phase decides how residents judge the result
Nobody who moves back into a redeveloped building inspects the columns. They notice whether the bathroom floor drains, whether the tiles sound hollow, whether water comes in at the window reveal in the first monsoon, and whether the kitchen platform is at a height they can work at. Every one of those is finishing work.
In our experience, the complaints that follow a redevelopment almost never concern structure. They concern seepage at bathroom junctions, cracked or hollow tiles, doors that bind because floor levels changed between rooms, and window frames that were fixed before they were checked for square. Most of these are decided in the first days of the finishing programme, by the sequence the work is done in, rather than at the end.
Scale makes this harder, not easier. When a developer is finishing several hundred flats across multiple wings, the standard achieved in the sample flat tells residents very little. What matters is whether the same supervision is applied to the three hundredth flat as to the first.
What a redevelopment boom does to finishing quality
More redevelopment projects running at once means more demand for skilled finishing labour, in particular tilers, waterproofing applicators and masons who can set out a staircase properly. When demand for those trades rises faster than the supply of good supervisors, the common failure is not bad materials. It is thin supervision, work covered before it is tested, and trades stacked on top of each other to make a date.
- Waterproofing covered by screed and tiles before a ponding test has been done and recorded.
- Concealed plumbing closed in before it has been pressure tested.
- Tiling started from a floor edge rather than a struck line, so joints drift across the room.
- Window frames grouted in without checking square and plumb, which shows up as a sash that will not close.
- Snagging done by the developer's sales team rather than by someone who knows what to look for.
These failures are avoidable, and none of them requires more expensive material. They require hold points, where the next trade does not start until the last one has been checked, and records that prove the check happened.
Questions a society should ask about finishing before it signs
The development agreement is the society's main point of leverage. Once it is signed and members have vacated, the society's ability to change the finishing specification drops sharply. These are the questions we would want a committee to ask while it still has that leverage.
- Is the finishing specification written out room by room, with named materials and grades, rather than 'as per sample flat'?
- What method is specified for bathroom and terrace waterproofing, and will it be ponding tested before it is covered?
- Who is responsible for the finishing phase: one contractor running all trades, or separately appointed trades coordinated by the developer?
- Will members, or a representative the society appoints, be allowed to inspect flats at defined stages rather than only at handover?
- How are defects reported after possession, and what is the process under the developer's defect liability for the sale and rehabilitation components?
- Is there a floor-by-floor finishing programme, and what happens to the rent or transit arrangement if finishing overruns?
For the sale component of a project registered with MahaRERA, the developer's defect liability and MahaRERA's quality assurance expectations apply. Our article on MahaRERA's quality assurance certificate explains how that plays into finishing records. Whether and how those protections extend to the residents' own flats depends on the project structure and the agreements, which is one more reason to take legal advice.
The rehabilitation flats deserve the same finish as the sale flats
In any redevelopment that includes a sale component, there are two kinds of flat in the same project: the ones the developer sells on the open market, and the ones handed back to existing residents. The commercial incentive to finish the sale flats well is obvious, because buyers compare them against every other project in the area. The incentive on the rehabilitation flats depends almost entirely on what the agreement says and how closely the society watches.
Our view, from working on both sides of such schemes, is that the cheapest way to finish a rehabilitation building well is to finish it the same way as the sale building: the same waterproofing method, the same tile bedding, the same hold points, the same supervision. Running two standards on one site costs the developer more in management than it saves in material, and it produces the kind of complaints that stay with a project for years.
A society can protect itself here with one sentence in its agreement: that the residents' flats will be finished to the same specification and the same method as the sale flats, with the specification attached. It is not a guarantee, but it gives the committee a clear standard to point at during construction.
A short checklist for societies in 2026
- Get the structural audit done and read it. Its category decides how much time you actually have.
- Commission a feasibility report from an independent consultant before you entertain offers.
- Compare builder-led redevelopment and self-redevelopment on the same feasibility numbers, not on promises.
- Visit at least two completed buildings by any developer or contractor you shortlist, and speak to residents, not the sales office.
- Write the finishing specification into the agreement, room by room, with the waterproofing method stated.
- Agree how the society will inspect the work during construction, not only at possession.
- Keep minutes, notices and consents in order. The 2026 amendments to the co-operative society rules set stricter procedures for redevelopment meetings.
- Take independent legal advice on every agreement before any member signs.
What the numbers do not tell you
A report on the market is not a report on your building. The figures describe the city in aggregate. They do not tell you whether your plot can support a viable redevelopment, whether your society has the consensus to see one through, or how long approvals will take in your ward.
They also say nothing about outcomes for residents once projects are complete: how many redevelopments finished on time, how many residents were paid rent without interruption, or how many new buildings needed significant repair within a few years. Those are the questions a society has to answer project by project, usually by visiting completed buildings by the developer or contractor it is considering and talking to the people who live there.
Headline growth can also hide stalled projects. Every experienced committee member in the western suburbs knows of a building where members have been out of their homes far longer than the agreement said. Growth in launches is not the same as growth in completions.
Repair, redevelop or wait: a practical frame
Not every old building should be redeveloped now, and not every building that should be can be. A society trying to decide usually weighs three things: what the structural audit says, what repairs would cost against the building's remaining life, and whether a redevelopment offer on the table is genuinely good.
If the structural audit calls for minor repairs, a well-planned repair after the monsoon may buy the building years and let the society take its redevelopment decision without pressure. Our article on the post-monsoon repair window explains why the weeks between the last heavy rain and the end of the year are the right time for that work. If the audit calls for major structural repair or places the building in a dangerous category, the calculation changes; our explainer on the BMC's C1, C2 and C3 categories covers what each one means.
Where Chamunda Constructions fits in a redevelopment
Chamunda Constructions takes on complete finishing work once the RCC structure is ready. On a redevelopment, that can mean working for the developer on both the sale and rehabilitation components, or, in a self-redevelopment, being appointed by the society or its project management consultant as the finishing contractor. Either way, the scope runs from waterproofing and concealed services through tiling, dado, kitchens, bathrooms, windows, lobbies and staircases to snagging and handover.
Bhadresh Chavda visits a site before the company commits to it, walks the structure floor by floor, and sets the finishing sequence from what is actually there rather than from the drawings alone. On a redevelopment, where residents are counting the months, that sequence is what keeps the finishing programme from becoming the part of the project that overruns.
