Slots recorded per building wing in the filing. MahaRERA does not publish a two wheeler or four wheeler split, visitor parking, or the sanctioned allotment, so this is provision as filed and not a comparison against the approved plan.
Land and ownership
MahaRERA has published no encumbrance declaration for this project. That is silence on the question, and not a record of clear land.
Approvals and building plan
Project account and cost
70 percent of buyer money must sit in the project account. Account numbers are not published by MahaRERA, so check that your agreement for sale names a designated account for this project and pay into that account only.
Certifying professionals and partners
Form 1, 2 and 3 certificates from these professionals release the promoter's withdrawals from the 70 percent account.

The permission chain
The permissions a project needs, in the order they happen, matched to MahaRERA's own document slots. A slot on the file means the promoter uploaded a document there; it is not proof the permission was granted, and the filing carries no issue dates. An empty slot is not proof an approval is missing.

Frequently asked questions
What does it mean that Cornerstone shows as registration lapsed on MahaRERA?
A registration runs until the completion date the promoter declared. If the project is neither completed nor extended by then it lapses, and a de-registration or revocation ends it by order. In every case the promoter may no longer legally advertise, market or sell in the project, and the Authority can act under section 7 against a defaulting promoter. What it does not do is cancel an agreement for sale you have already signed, or extinguish your section 18 right to delay interest or refund; those run from your agreement, not from the registration. Get the current position from the promoter in writing, verify it on the MahaRERA portal, and take legal advice before paying any further instalment.
What are my rights if Cornerstone is delayed beyond 30 Jun 2025?
Under section 18 of the RERA Act you may stay in the project and claim interest for every month of delay, or exit and claim a full refund with interest. In Maharashtra the rate is SBI's highest MCLR plus 2 percent, currently 10.90% per annum (June 2026). The free delay interest calculator on ReraGenie puts a rupee figure on any delay. Claims are filed as MahaRERA complaints with a Rs 5,000 fee.
How do I verify and contact the developer of Cornerstone?
The registered promoter entity is Shree Sadguru & Deluxe JV, an others as per the filing. Neither this filing nor this promoter's other MahaRERA registrations disclose a CIN, LLPIN or GSTIN for this entity. Your agreement for sale must name this exact entity, not a group brand name. The promoter's registered address and contact details are on the project's MahaRERA listing (scan the QR code on any advertisement) and in its filed documents. The Rs 499 buyer report includes all of them as a single ZIP, foldered by type.
Is my payment protected in Cornerstone?
Partly, by law. 70 percent of every buyer payment must go into the project's designated bank account, withdrawable only against architect, engineer and CA certificates as construction progresses; since July 2024 MahaRERA requires a three-account structure for collections. Separately, a promoter cannot take more than 10 percent of the price before signing a registered agreement for sale (section 13). Neither rule guarantees completion; they limit how far your money can travel from the project.
How do I read the complaint cases filed against Cornerstone?
Each case number above is a complaint MahaRERA hears in public. On the MahaRERA website, open Complaint Details and search the CC number: the order PDFs, hearing dates and disposal status are free to download. Orders bind the promoter. Before booking, check whether past orders were complied with, not just whether complaints exist; an ignored order is a stronger warning than the complaint itself.
How current is the construction progress shown for Cornerstone?
Promoters must file a quarterly progress report within 20 days of each quarter end, certified by the architect (Form 1), engineer (Form 2) and chartered accountant (Form 3). The figures above come from the latest filing, so they can trail the site by up to a quarter. A promoter who stops filing QPRs altogether invites penalties under section 61, and a stale filing date is itself a warning sign worth checking on the portal.
What should I check before booking in Cornerstone?
Four things this page cannot decide for you: that the carpet area in your agreement matches the filed carpet area (the model agreement allows only a 3 percent variation, with a refund right below that); that the agreement follows MahaRERA's model clauses with deviations highlighted; the promoter's record on their other projects, not just this one; why the completion date was revised and what the new timeline depends on. The Rs 499 buyer report works through all of them from the filings.
