Buying in a society redevelopment project: the extra checks that apply

A redevelopment purchase is two transactions wearing one brochure: you are buying a new flat from a developer, inside a bargain that developer struck with an old society. The standard verification file covers the first transaction. The five checks below cover the second, and the second is where redevelopment projects actually fail.

Why the second transaction matters to you#

Redevelopment supply dominates in the older cores, in Mumbai through the Regulation 33 schemes and society redevelopments, in Pune increasingly under UDCPR's provisions, so avoiding it is not realistic, and not necessary: the land titles are often cleaner than greenfield's, decades in one society's name. In Mumbai, check how that land is held too: a society on collector's land needs the Collector's permission and a premium to redevelop, unless the land is first converted to freehold. What is different is the dependency chain. Your flat exists because a society consented, an agreement allocated the built area, occupiers agreed to move, and a rehab building must rise. A defect anywhere upstream, consent challenged, agreement disputed, rehab stalled, stops your tower with it.

An analogy: buying a greenfield flat is buying a ticket for a new train. Buying a redevelopment flat is buying a ticket for a train that must first deliver its current passengers home. Your timetable depends on both journeys, and the awkward part, as the measurements below show, is that the published filings usually describe only one of them.

The five extra checks#

Reading the filings redevelopment-style#

Everything from the portal check applies unchanged, entity, status, dates, QPR rhythm. The redevelopment-specific reading is the one everybody recommends and almost nobody can actually do, so it is worth being precise about where it stops.

The theory is sound. A registration reporting 55 percent overall could be hiding a rehab building at 20 and a sale tower at 80, which would be a developer consuming the scheme's sale value while deferring its obligations. To see that you need three things at once: the filing has to declare rehab units, it has to split them across buildings so one is identifiably the members' and another identifiably yours, and both buildings have to carry construction progress. Across the whole register that chain survives on very few projects.

So the honest version of this check is: try it, expect it not to work, and do not read its absence as a warning. A scheme that files no rehab units is overwhelmingly likely to be a scheme that simply did not itemise them, not one hiding something. Where the split does resolve, read it. Where it does not, which is nearly always, the question moves to the seller (which building rehouses the members, what stage is it at, get it in writing) and to the site, where two structures at visibly different heights answer it in a minute.

And read the direction carefully if you do get a number. On the 195 projects where both sides are legible, the median gap between sale progress and rehab progress is zero. Sale runs more than ten points ahead of rehab on 17 of them; rehab runs more than ten points ahead of sale on 30. The lagging-rehab pattern is real and worth catching, but it is not the normal state of a redevelopment scheme, and a buyer who treats any gap as evidence of bad faith will mostly be wrong.

What the filings do carry on every covered project, redevelopment or not, is the certificate trail, the extension history with the promoter's own stated reason, the complaints and the litigation. On a redevelopment those are more useful than a progress split anyway, because a society-developer dispute normally surfaces there first.

And run the promoter's record with a redevelopment lens: their completed schemes specifically. A developer who has delivered rehab buildings on time, twice, has passed the test that matters; one whose only deliveries are greenfield is bringing a learner's licence to the harder discipline.

Neha (illustrative, as ever) bought her Mulund redevelopment flat after exactly this layered read: the development agreement's architecture confirmed through her lawyer, consent uncontested, and conveyance completed by the old society years earlier. She happened to land in the rare case where the filing itemised both buildings, and it showed the rehab building topped out two quarters ahead of her tower. On the competing project half a kilometre away, ten percent cheaper, the filing said nothing at all about rehab; what answered was a site visit, a rehab plinth beside a sale tower at the eighth slab, and a sales team that would not put the rehousing schedule in writing. The second answer cost her an afternoon and told her more than the first.

Where to run the parts that are free#

The standard file is public on every covered project. The free project pages carry the registration and its status, the promised completion date and every extension filed against it, the quarterly construction progress, the disclosed complaints and litigation, and the promoter's other registrations with their delivery record. On a redevelopment the last of those is the one to spend time on, read with the lens above: a promoter whose completed schemes are redevelopments has passed the harder test.

The Rs 499 buyer report assembles that for one project and adds what a single filing cannot show: the promoter's concurrent commitments, the district's own slip distribution, and where this scheme's pace sits among its neighbours. It reports the rehab split where the filing supports it and says so plainly where it does not, which on a redevelopment is most of the time. The four checks the register genuinely cannot answer, the agreement, the consent, the conveyance and the rehousing schedule, stay your lawyer's and the seller's; no report can buy you out of asking for them.

These checks answer whether the scheme is sound. Whether its price is a bargain is a separate question with separate sources, and it is worth reading the value case for redevelopment stock before deciding that a discount you were quoted is one.

The one-line summary#

A redevelopment flat rides on the old society's bargain: confirm the agreement's architecture, the consent and the conveyance alongside the standard file, ask in writing which building rehouses the members and when, and let the train's first journey, the passengers going home, tell you whether yours will run on time.

Methodology and sources#

• Rehab-unit declarations, the building-level split and construction progress: ReraGenie analysis of 55,885 published MahaRERA projects, as updated on 17 September 2026. A project counts as declaring rehab units when its filed unit-level sales table carries a non-zero rehab count; 18,877 projects file that table at all, 3,174 declare rehab units, 196 split them across buildings and 195 carry filed progress on both sides.
• The progress comparison averages the applicable, filed activity percentages for each building, capped at 100, since promoters occasionally file individual activities above it.
• Conveyance and the promoter's four-month obligation: the Maharashtra Ownership Flats Act, 1963, and the Maharashtra Co-operative Societies Act, 1960, under which the deemed conveyance remedy sits.
• MahaRERA files no development agreement terms, no consent record and no transit rent schedule, so nothing in this article's checklist beyond the progress reading can be answered from the register. That is the reason four of the five checks name a document rather than a page.
