Cluster redevelopment in Mumbai is back in focus after MHADA's 2026 colony tenders. A plain-language guide for residents: cluster vs standalone redevelopment, the rules, the trade-offs and what to ask.
Cluster redevelopment in Mumbai means rebuilding a group of old buildings, or an entire colony, as a single planned scheme instead of one building at a time. It has been part of the city's rules for years, but 2026 has put it firmly back in the news. In February, MHADA's vice-president and CEO said the authority was opening 800 to 1,000 acres for cluster redevelopment, and on 2 June 2026 MHADA declared the highest bidders for three large colony clusters in Andheri West, Bandra and Worli. This guide explains, for residents rather than developers, how cluster redevelopment differs from the standalone redevelopment most societies know, what the rules broadly say, and what the trade-offs are.
It is written by Chamunda Constructions, a Kandivali West civil and finishing contractor founded in 2004 by Bhadresh Chavda. We carry out the finishing phase of residential buildings, including redevelopment and SRA schemes, and we are not advisers on planning law. What follows is general information, not legal or planning advice, and details of the regulations should be checked with a qualified architect, planner or lawyer before any decision is made.
Cluster redevelopment in Mumbai: the basic idea
In standalone redevelopment, one society on one plot redevelops its own building. The new building has to fit on that plot, with that plot's road access, setbacks and development potential. The result is often a tall, narrow tower on a small plot, surrounded by other old buildings that will be redeveloped one by one over the next decade, each on its own timeline.
In cluster redevelopment, several plots are combined and replanned together. The combined area can be laid out with proper internal roads, open spaces, amenities and infrastructure, and the development potential of the whole area is used more efficiently. Residents of all the old buildings are rehoused within the scheme, and the additional floor area is used for sale housing that funds the project.
The simplest way to think about it: standalone redevelopment replaces a building; cluster redevelopment replaces a neighbourhood. That difference in scale drives almost every other difference in this guide, from who the developer is likely to be, to how long residents wait, to how much say each society has over the result.
Why cluster redevelopment is back in focus in 2026
The case for clusters rests on land. At an ET Realty conclave in February 2026, as reported by Outlook Money, MHADA vice-president and CEO Sanjeev Jaiswal said that nearly 90 per cent of Mumbai's developable land has already been used. He described MHADA opening 800 to 1,000 acres for cluster redevelopment, planned as integrated layouts of 60 to 100 acres with infrastructure, open space and transport links, and said 60 to 70 per cent of new housing supply was expected to come from approved or pipeline cluster projects.
The wider redevelopment market is moving the same way. The JLL and NAREDCO Maharashtra report 'Redevelopment in Mumbai: The Inflection Point', released on 3 September 2026, counts more than 1,000 redevelopment projects in the city since 2020, and its coverage in the Free Press Journal mentions large cluster-scale schemes such as the Juhu Lane-Gilbert Hill cluster and Motilal Nagar in Goregaon. Our article on what the 2026 redevelopment numbers mean covers that report in more detail.
MHADA's 2026 colony cluster tenders
The clearest sign of the shift is MHADA's own colonies. According to the Free Press Journal, MHADA's Mumbai Board issued tenders on 8 April 2026 for three colony clusters: S.V.P. Nagar in Andheri West, Bandra Reclamation in Bandra and Adarsh Nagar in Worli. Bids closed on 18 May, financial bids were opened on 27 May, and on 2 June 2026 the highest bidders were declared.
- S.V.P. Nagar, Andheri West, about 73.89 acres: a consortium including Hanura Realty, a JSW Steel subsidiary, with Chandak Realtors, Premsagar Infra Realty and Vantier Realty.
- Bandra Reclamation, about 98.27 acres: Adani Properties.
- Adarsh Nagar, Worli, about 34.33 acres: Adani Properties.
Together the three cover more than 206 acres. The property news site PropNewz has reported that some resident groups have challenged the tender process in the Bombay High Court, and that sales in these schemes are some way off. Residents of those colonies should follow the official process and their own legal advice rather than news coverage, including this article.
What the regulations say, broadly
In Greater Mumbai, cluster redevelopment of old buildings is primarily governed by Regulation 33(9) of the Development Control and Promotion Regulations 2034 (DCPR 2034), which provides for Urban Renewal Cluster Development Schemes. Other regulations in the 33 series cover other kinds of redevelopment, such as cessed buildings, MHADA layouts and slum rehabilitation, and large schemes can involve several at once.
Published summaries of Regulation 33(9), including one by the planning consultancy Kutir Group, describe a minimum cluster area of 4,000 square metres in the island city and 6,000 square metres in the suburbs and extended suburbs, and a total permissible FSI of up to 4.0 on the gross plot area, with incentive floor area linked to the rehabilitation area. Coverage of the JLL and NAREDCO report likewise refers to up to 4.0 FSI for cluster and slum schemes. The regulation has been modified since DCPR 2034 was first notified, including a set of changes in July 2021, so the current text is what matters for any real scheme.
Consent is the other key element. Cluster schemes require written consent from a defined share of eligible occupants, and the thresholds and how they are counted are set out in the regulation and related government decisions. This is exactly the kind of detail on which residents need current, professional advice rather than a summary.
Terms residents will hear in cluster meetings
Cluster meetings tend to be full of planning vocabulary. A few terms come up in almost every discussion, and it helps to know them before the first presentation. Our construction glossary for Mumbai flat buyers covers many more.
- Rehabilitation area or rehab component: the new homes built for existing residents, usually at no cost to them.
- Free-sale or sale component: the additional flats the developer sells on the open market to fund the scheme.
- Incentive FSI: additional floor area granted as an incentive for redevelopment, often linked to the rehabilitation area.
- Gross plot area: the total area of the combined plots before deductions such as road widening.
- Layout: the master plan for the whole cluster, showing building positions, roads and open spaces.
- Phasing: the order in which buildings are demolished and rebuilt across the scheme.
- Transit accommodation: temporary housing for residents while their new homes are built.
- Corpus fund: a lump sum usually set aside for the new society to help with higher maintenance costs in a taller building.
If a presentation uses a term you do not understand, ask for it to be explained in writing. A developer or consultant confident in its proposal should have no difficulty doing that.
Cluster vs standalone redevelopment: the main differences
- Scale: standalone covers one building or plot; cluster covers many buildings, a colony or a whole block.
- Planning: standalone fits a building into an existing street; cluster replans the layout, with internal roads, open spaces and amenities.
- Development potential: cluster schemes can access higher total FSI and incentive area under the regulations, which is part of what makes large schemes viable.
- Decision-making: standalone needs one society's consent; cluster needs consent across many buildings and owners, which takes longer.
- Developer: standalone projects are often done by small and mid-sized developers; cluster schemes usually need large developers with the capital to carry them.
- Timeline: standalone projects can move from decision to possession faster; cluster schemes are usually phased over many years.
- Residents' voice: in standalone, a society negotiates directly; in cluster, each society is one voice among many.
The case for cluster redevelopment
The strongest argument for clusters is the city itself. Building-by-building redevelopment tends to produce tall towers on streets that were designed for three-storey buildings, with the same narrow roads, the same drainage and the same shortage of open space serving many times more people. A cluster scheme can widen roads, create proper open spaces, upgrade water supply and drainage, and plan schools, health facilities and parking across the whole area.
For residents, clusters can also make redevelopment possible where it otherwise would not be. A small building on a narrow lane may have no viable standalone redevelopment at all. Combined with its neighbours, it can become part of a scheme that works.
There is also a construction argument. A large planned scheme can be built with better site logistics, dedicated material storage and a finishing programme that runs building by building with a stable, trained workforce, rather than a string of small sites each starting from scratch.
Maintenance is a less obvious benefit. A planned layout can be designed with shared services that are easier to maintain: one sewage treatment plant rather than a dozen, water tanks sized for the whole scheme, and common areas designed with maintenance access in mind. Individual towers squeezed onto small plots often end up with services tucked into whatever space is left, which makes every future repair harder. For a society that will look after its new building for the next sixty years, how easy the building is to maintain matters as much as how it looks on handover day.
The case against, or at least for caution
The weaknesses of clusters are the other side of their strengths. Many owners and many societies mean many opinions, and a single dissenting group can slow a scheme for years. Large schemes are phased, and residents in later phases may wait much longer than residents in earlier ones. Rent or transit arrangements must hold for the whole period. And because the developer is dealing with a large number of residents, each society's ability to negotiate its own terms is weaker.
- Longer and less predictable timelines, especially where consent or litigation is involved.
- Phasing, which can mean some residents move into new homes years before others.
- Transit accommodation that may be less convenient than a rented flat near the old building.
- Less individual negotiating power for each society or owner.
- Heavy dependence on a single developer's finances over a long period.
How a cluster scheme typically unfolds
Every scheme is different, and the route depends on who owns the land and which regulation applies. For MHADA colonies, MHADA is the landowner and runs the tender; for private clusters, a developer usually assembles consents building by building. The broad sequence, though, is recognisable across most schemes.
- Identification of the cluster area and a survey of existing buildings, occupants and eligibility.
- Selection of a developer, either through a public tender, as with MHADA's 2026 colonies, or through negotiation with each society in a private cluster.
- Consent-gathering from eligible occupants, to the thresholds the applicable regulation requires.
- Master planning of the whole layout: building positions, roads, open spaces, amenities and phasing.
- Approvals for the layout and for each phase, and MahaRERA registration for sale components.
- Phase one: often the construction of rehabilitation buildings on vacant or cleared parts of the site, so that residents can move directly into new homes.
- Later phases: demolition of vacated old buildings, construction of further rehabilitation and sale buildings, and infrastructure.
- Handover of each phase, with the occupation certificate and formation or transfer of the new societies.
Where a scheme can build rehabilitation housing first, residents may move once, directly from the old building to the new one. Where it cannot, residents move to transit accommodation or rented homes and wait for their phase. That single question, which comes first, has a larger effect on residents' lives than almost anything else in the agreement.
Transit accommodation, rent and the waiting period
In standalone redevelopment, most residents receive rent and find their own temporary homes nearby. In large schemes, and in schemes run by public authorities, transit camps are also used. The Free Press Journal's report on the June 2026 MHADA tenders mentions transit rent during the redevelopment period and a corpus fund for maintenance as part of what residents are to receive, but the specific terms depend on each tender and agreement.
Whatever the arrangement, residents should understand three things in writing: how long it is expected to last, what happens if it lasts longer, and who is responsible for paying if the developer's finances change. On long phased schemes, those answers matter more than the size of the new flat.
Living next to a cluster under construction
A large scheme under construction affects the streets around it for years: construction traffic, noise, dust, road diversions and changes to water and drainage. The BMC's dust mitigation rules for construction sites, which we cover in a separate article, apply to large schemes as to small ones, and neighbours are entitled to expect them to be followed. Societies next to a cluster site should keep a record of problems, raise them with the developer first and escalate to the ward office if needed.
It is also worth checking the condition of your own building before a large neighbouring excavation starts. A simple photographic record of existing cracks, dated and shared with the developer, can prevent later arguments about whether damage was caused by the neighbouring works.
What residents in a proposed cluster should ask
Residents approached about a cluster scheme often feel that the decision is being made above them. Some of it is, but there are still questions every society can and should put in writing.
- Which regulation is the scheme being proposed under, and what are the consent requirements?
- What carpet area will each existing resident receive, and is it stated per flat in the agreement?
- Which phase will our building be in, and what is the timeline for that phase specifically?
- What rent or transit accommodation is offered, for how long, and what happens if the phase overruns?
- What corpus or maintenance fund is provided for the new building?
- What is the finishing specification for rehabilitation flats, and is it the same as for sale flats?
- How will residents' representatives inspect construction during the works?
- What defect liability applies to the rehabilitation buildings after possession?
Where the finishing phase fits in a cluster scheme
A cluster scheme is not one construction project but many, run in sequence. Each building goes through structure and then finishing, and the finishing of one building overlaps with the structure of the next. For residents, the finishing is still what they will live with: the bathroom that drains or does not, the tiles that stay flat or crack, the windows that seal or let in the monsoon.
Large schemes create a particular risk: the finishing standard slipping from one building to the next as the site's pressure changes. The first building gets the attention; later buildings get whatever labour is available. The protection is a finishing specification and method fixed for the whole scheme, hold points that apply to every building, and a contractor who keeps the same supervision across phases.
We have seen this at a smaller scale on multi-building schemes. Tower 28 in Malad East, the sale component of the Navjeevan SRA redevelopment developed by Right Channel Constructions, is part of a scheme of about ten buildings, with four sale wings of roughly 22 floors each alongside separate rehabilitation buildings. The lesson from schemes like that is that finishing has to be planned as a programme across buildings, not re-planned for each one.
What cluster schemes mean for the finishing trades
If even part of the 800 to 1,000 acres MHADA has described comes to construction, the demand for skilled finishing trades in Mumbai will rise sharply over the next decade. Tilers, waterproofing applicators, stone masons and supervisors who can run a floor are already in short supply on busy sites. Large schemes will compete with each other and with standalone redevelopment for the same people.
For developers, that makes the choice of finishing contractor more important, not less. A contractor with a stable team and a documented method can hold a standard across buildings. One assembling labour project by project is more likely to deliver a good first building and a weaker fifth one.
Standalone redevelopment is not going away
None of this means standalone redevelopment is finished. Most co-operative buildings in the western suburbs are not in MHADA layouts or large colonies, and for them standalone redevelopment, builder-led or self-redevelopment, remains the realistic route. Our guide to self-redevelopment for Mumbai societies covers the second option in detail, and our society redevelopment finishing checklist applies to both.
In practice, many neighbourhoods will see both. A large colony nearby is replanned as a cluster while the co-operative buildings on the surrounding streets redevelop one by one. Residents in those streets are affected by the cluster, through traffic, construction and changes to local infrastructure, even though they are not part of it.
A note on dangerous buildings and clusters
One of the arguments for clusters is that they can rehouse residents of old, unsafe buildings that could not be redeveloped individually. That is true in principle, but a cluster scheme takes years to reach any given building. A building that a structural audit places in a dangerous category needs action on its own timeline, which may mean vacating or urgent repair well before any cluster scheme arrives. Our explainer on the BMC's C1, C2A, C2B and C3 categories covers what each means.
Working with Chamunda Constructions on large schemes
Chamunda Constructions takes on complete finishing work for Mumbai developers once the RCC structure is ready: waterproofing, concealed services, tiling, dado, kitchens, bathrooms, windows, lobbies, staircases and snagging. On multi-building schemes, we plan the finishing programme across buildings and floors from the start, so that labour, materials and supervision stay consistent rather than being re-assembled for each phase.
Bhadresh Chavda has led the company since 2004 and still visits every site before we commit to it. If you are a developer planning the finishing of a redevelopment or cluster scheme, or a society's consultant looking at the finishing specification, we would be glad to visit and discuss it.
