What is RERA and Why Should You Care?
Before RERA (2016), buying property in Mumbai was a gamble. Developers could sell unregistered projects, divert your money to other sites, quote inflated areas, and delay possession by years with zero consequences.
RERA changed all of that. The Real Estate (Regulation and Development) Act gives Mumbai homebuyers enforceable legal rights. MahaRERA — Maharashtra's implementation — is one of the most active state authorities in India.
How to Verify RERA Registration (2 Minutes)
- Go to maharera.maharashtra.gov.in
- Click "Search Project"
- Enter the project name or RERA number (format:
P51800XXXXX) - The listing shows everything: approved plans, carpet areas, expected completion, promoter details, financial statements
What to Look For on the RERA Page
| Field | What It Tells You |
|---|---|
| Proposed completion date | The legal deadline. Delays after this trigger compensation |
| Registered carpet area | The ONLY area that matters. Ignore super built-up quotes |
| % of construction completed | Updated quarterly by the developer. Cross-reference with a site visit |
| Litigations | Any legal disputes involving the project. Red flag if many |
| Promoter's other projects | Check delivery track record across all their projects |
Carpet Area — The Only Number That Matters
RERA mandates that all sales are based on carpet area — the actual usable space within the walls of your flat. This is what you should evaluate:
- Carpet area — what you can use. The legal measurement under RERA
- Built-up area — carpet + wall thickness. Typically 15-20% more. Ignore this
- Super built-up area — includes common areas (lobby, staircase, amenities). Can be 30-50% more than carpet. Developers love quoting this. Ignore it
The 70% Escrow Rule
This is RERA's most powerful protection. Developers must deposit 70% of all buyer payments into a separate escrow account.
- Funds can only be withdrawn proportional to construction completed
- Withdrawal requires certification by both an engineer and a chartered accountant
- This prevents the pre-RERA practice of using your money to buy land for another project
What Happens When Your Developer Delays
If the developer misses the RERA-registered completion date, you have two options:
Option A: Continue waiting
Developer pays you interest at SBI MCLR + 2% (currently ~10.5% per annum) on your total payment until possession is delivered.
Option B: Full refund
Withdraw from the project entirely. Developer refunds 100% of your payment + interest at the same SBI MCLR + 2% rate.

2026 Regulatory Updates
Maharashtra Stamp Bill 2026: The new Stamp Bill has been passed, streamlining stamp duty collection and bringing greater transparency to property transactions. Key changes include digital stamping mandates and simplified adjudication processes.
Gram Panchayat rules tightened for plotting projects: MahaRERA has tightened scrutiny of plotting/layout projects in Gram Panchayat areas. Developers must now provide clearer title documentation and NA conversion proof before RERA registration. This is particularly relevant for buyers looking at plots in extended suburbs and MMR townships — always verify RERA registration and NA status before committing.
Frequently Asked Questions
Is RERA registration required for resale flats?
RERA registration is project-level, not unit-level. When buying a resale flat, verify that the developer's project is registered on maharera.maharashtra.gov.in. Once a project is delivered with an OC, the RERA registration is considered complete — but the project's history (delays, complaints) remains on record and is worth checking.
What does a MahaRERA number look like, and what does it mean?
MahaRERA numbers follow the format P51800XXXXX. The 'P' means project registration (as opposed to 'A' for agent). '5' is Maharashtra's code. '18' denotes Mumbai suburban district. Always ask the developer for this number and verify it yourself on the portal — never accept a screenshot or brochure copy as proof.
What is RERA Form Q and why should buyers check it?
Form Q is the quarterly compliance update that every registered developer must file with MahaRERA — covering construction progress, funds collected, funds utilised, and any changes to the project timeline. It's publicly available on the MahaRERA portal. If a developer is consistently late filing Form Q, or their construction progress percentage doesn't match what you see on site visits, that's a red flag worth investigating before signing.
Can I stop paying installments if the developer delays significantly?
Under RERA, if the developer misses the registered possession date, you have the right to cancel the booking and receive a full refund with interest at SBI MCLR + 2%. However, unilaterally stopping payments before formally invoking RERA cancellation can expose you to breach-of-contract claims under the sale agreement. Always consult a property lawyer and send a formal notice before stopping payments — or file a MahaRERA complaint (₹5,000) to put the delay on record first.
Does RERA cover commercial properties too?
Yes. RERA covers commercial real estate projects of 500 sqm or more, or those with more than 8 units, regardless of whether they are residential or commercial. If you're buying an office space or retail unit in an under-construction mixed-use tower, the same RERA verification and escrow rules apply.
What happens to my booking if the developer goes bankrupt before possession?
The 70% escrow rule is specifically designed for this scenario — your money should be ring-fenced in a dedicated account accessible only for project-related expenses. In practice, enforcement has been imperfect; some developers have faced MahaRERA action for diverting escrow funds. If a developer is declared insolvent, the case moves to the National Company Law Tribunal (NCLT) under IBC proceedings, where homebuyers now have financial creditor status — ahead of most other creditors. Still: always verify developer track record and prefer listed developers (Macrotech/Lodha, Godrej Properties) where financial accountability is higher.
