Buying a home that does not exist yet asks for a certain kind of trust. You pay in stages, watch a site slowly rise, and wait for keys that may be three or four years away. For many families, under construction projects in Mumbai still make sense, because they offer newer layouts, staggered payments and a wider choice of floors and views than the resale market. The question is how well the law protects you while you wait.
The short answer is that the law protects you far better than it did a decade ago. The Real Estate (Regulation and Development) Act, 2016, and its Maharashtra regulator, MahaRERA, changed the rules for developers and buyers alike. Knowing exactly what those rules cover, and where they stop, is what separates a confident purchase from an anxious one.
Why Do Buyers Still Choose Under Construction Projects in Mumbai?
Ready flats let you move in at once, but they often come with older floor plans, limited inventory and little room to choose. Mumbai under construction projects, by contrast, usually offer the full range of floors, facings and configurations at launch. Payments are linked to construction milestones, which spreads the financial load and gives a family time to plan the move.
There is a trade-off, of course. You carry the risk of delay, and if you are paying rent while also servicing a home loan, a late handover costs real money. Buyers who go this route should be honest about how long they can wait and how much buffer their finances can absorb if the timeline slips by a year.
What Does MahaRERA Registration Actually Protect?
Under the Act, a real estate project with a plot area above 500 sq m or more than eight apartments must be registered with the state authority before it can be advertised or sold. The registration number has to appear in advertisements, and the project’s details sit on the public MahaRERA portal: approvals, the promoter’s declared completion date, litigation status and periodic progress updates.
Registration also locks in what is being sold. Homes must be sold on carpet area, the usable floor space within your walls, rather than on loosely defined built-up or super built-up figures. A developer cannot change sanctioned plans or specifications without the written consent of the buyers affected. And before a registered agreement for sale is signed, the promoter cannot take more than 10 percent of the cost of the flat as an advance or application fee.
How Does the 70 Percent Escrow Rule Protect Your Money?
One of the most important protections sits in the money trail. Developers must deposit 70 percent of the amounts collected from buyers for a project into a separate bank account, and that money can only be used for land and construction costs of that same project. Withdrawals must be in proportion to the work completed and certified by an engineer, an architect and a chartered accountant.
This rule targets an old problem, where money collected for one building was diverted to buy land or start another. It does not make a project risk free, but it means your instalments are far more likely to be turned into concrete on the site you are actually buying into.
What Happens If Possession of Your Flat Is Delayed?
If the developer fails to hand over the flat by the date stated in the agreement for sale, the Act gives you two routes. You can withdraw from the project and claim a refund of the amounts paid with interest, plus compensation where applicable. Or you can stay invested and claim interest for every month of delay until possession is handed over. Complaints are filed with MahaRERA, and conciliation is available before a formal hearing.
Protection continues after possession. If you notice a structural defect, or a defect in workmanship, quality or services, within five years of handover, the developer must fix it within 30 days at no further cost to you. Where that does not happen, you are entitled to compensation. Keep a dated record of any defect you report, with photographs, since that record carries weight if a dispute arises.
Which Checks Should You Run Before Booking an Under Construction Building in Mumbai?
The law sets the floor, but your own homework decides the outcome. Before you book a flat in an under construction building in Mumbai, run through a few practical checks:
- Search the project on the MahaRERA portal and match the registration number to the advertisement.
- Compare the promoter’s declared completion date with the date written into your agreement for sale.
- Read the latest progress updates and visit the site to see whether the work matches them.
- Check whether the project or land has any pending litigation disclosed on the portal.
- Look at the developer’s completed projects and speak to residents about handover quality.
- Confirm which banks have approved the project for home loans.
Under construction residential projects in Mumbai vary widely in quality, even under the same rules. A developer’s past delivery is still the most reliable predictor of how your own handover will go.
Where Do Atmosphere O2, Ajmera Manhattan and Rustomjee Crown Sit Against Mahindra Lifespaces?
Atmosphere O2, developed by the Wadhwa Group with MICL and Chandak Group on the Goregaon Mulund Link Road in Mulund West, near Nahur station, is a useful example of how phased projects work in practice. Public listings describe a site of over seven acres, 2, 2.5 and 3 BHK configurations, a clubhouse and pools, with occupancy certificates reported for some towers while a later tower is still under construction. It is MahaRERA registered, and its mix of finished and rising towers lets buyers see delivered work before committing to a new phase.
Further south, Ajmera Manhattan by the Ajmera Group at Bhakti Park in Wadala East shows a project at an earlier stage. Listings describe two towers of ground plus 36 floors within a site of about 12.5 acres, with 2, 3 and 4 BHK homes, a MahaRERA registration and a declared completion date of December 2028, while the Bhakti Park monorail station and the Eastern Freeway sit close by. Rustomjee Crown in Prabhadevi offers a third pattern: a gated estate of about 5.75 acres with 3, 4 and 5 BHK homes in towers rising to 68 storeys, where the developer reports that Towers A and B have received their occupancy certificate. Looking up a delivered tower, a rising one and a later registration side by side on the MahaRERA portal is a useful exercise in itself.
Possession risk is where the brand behind a project counts for most, and that is the ground on which Mahindra Lifespaces makes its case. A buyer paying instalments over several years is, in effect, trusting the developer to finish what it has started, and the Mahindra Group’s legacy of trust gives that commitment a firmer footing. Its active project on LBS Marg, Kanjur sits a short distance south of Atmosphere O2 along the same eastern corridor, and more than 21,000 satisfied customers offer a large pool of past purchasers whose handover experience can be checked.
Who Offers Under Construction Homes Backed by a Long-Standing Name?
An under-construction purchase rewards patience only when the developer is still standing firmly behind the project at handover. Mahindra Lifespaces has been building homes for more than three decades under its Rise philosophy and today carries 55.50 million sq ft of active and upcoming residential space across cities. With active projects in Mumbai at Mahalaxmi and LBS Marg, Kanjur, the company gives buyers of under-construction homes a developer whose delivered communities can be seen before the first instalment is paid.
