MahaRERA Verification Guide for Mumbai Flat Buyers 2026
Every 3 BHK flat buyer in Mumbai must complete MahaRERA verification before signing any agreement or paying any token amount. The Maharashtra Real Estate Regulatory Authority, accessible at maharerait.mahaonline.gov.in, maintains a publicly searchable database of all RERA-registered projects and agents in the state. Skipping this step has cost buyers crores of rupees in stalled or fraudulent projects across Mumbai, Thane and Navi Mumbai. This guide explains exactly how to search, what to check and what red flags to avoid.
What’s Covered in This Guide
What Is MahaRERA and Why It Matters for Mumbai Buyers
MahaRERA (Maharashtra Real Estate Regulatory Authority) was established under the Real Estate (Regulation and Development) Act, 2016. Every residential project with more than eight apartments or a land parcel exceeding 500 square metres must be registered with MahaRERA before any sale, advertisement or booking can take place. As of 2026, over 47,000 projects and 50,000 agents are registered on the portal.
For buyers of 3 BHK flats in Mumbai, MahaRERA verification serves three critical purposes. First, it confirms the builder is legally permitted to sell. Second, it gives you access to the project’s approved layout, financial details and promised completion date. Third, it creates a legal record that protects you if the builder defaults or delays possession.
Before the RERA era, thousands of Mumbai buyers were trapped in stalled projects with no legal recourse. Today, a verified MahaRERA registration is the single most important document you should check before paying even a booking amount for a flat in Worli, Powai, Bandra West or any other Mumbai locality.
Key Rights MahaRERA Gives Buyers
Under RERA, you have the right to full disclosure of the approved plan, carpet area-based pricing, a standardised sale agreement and timely possession or compensation at 10.75% interest per annum on the amount paid. If the builder delays beyond the registered completion date, you can file a complaint with MahaRERA and seek a refund with interest. These are legal rights, not courtesies.
How to Search a Project on MahaRERA Step by Step
The MahaRERA portal at maharerait.mahaonline.gov.in is freely accessible. Here is the exact process to find a Mumbai project:
Step 1: Go to maharerait.mahaonline.gov.in and click on “Registration” in the top menu, then select “Projects”.
Step 2: You will see a search form. You can search by project name, MahaRERA registration number, promoter name or district. For Mumbai projects, select “Mumbai City” or “Mumbai Suburban” from the district dropdown.
Step 3: Type the project name as shown in the brochure or sales agreement. Be careful with spelling. The builder may have registered under a slightly different name, such as “Lodha Bellavista” instead of “Lodha Bella Vista”.
Step 4: Click “Search” and you will see a list of matching projects with their MahaRERA registration numbers. Registration numbers follow the format P51900XXXXXX for Mumbai projects.
Step 5: Click on the registration number to open the full project details page.
| Search Method | Best For | Notes |
|---|---|---|
| Project Name | When you have the project name from brochure | Try partial name if full name gives no results |
| Registration Number | When builder has shared the RERA number | Fastest and most accurate method |
| Promoter Name | To see all projects by a builder | Useful for checking builder’s track record |
| District Search | To browse all projects in an area | Choose Mumbai City, Mumbai Suburban or Thane |
What to Check on the MahaRERA Project Page
Opening the project page is just the beginning. There are twelve specific data points every Mumbai 3 BHK flat buyer must verify before proceeding.
1. Registration Status
The project status must show “Active”. If it shows “Lapsed”, “Revoked” or “Expired”, the builder is not legally permitted to sell or collect money. Walk away immediately. Do not accept any verbal assurance that the builder “is in the process of renewal”.
2. Completion Date
Check the declared completion date. If it has already passed and you are still being sold an under-construction unit, the builder is in default. You are entitled to a refund with interest if you have already paid. Note that MahaRERA does allow extensions under force majeure provisions, but the extension must be formally recorded on the portal.
3. Carpet Area and Unit Count
The portal shows the total number of units approved, the types (1 BHK, 2 BHK, 3 BHK) and their carpet areas. If the builder is quoting you a carpet area that does not match what is registered, that is a discrepancy you must raise in writing before signing anything. Mumbai flats are priced on carpet area since the RERA notification of 2017.
4. Approved Plans and Commencement Certificate
Scroll to the document section. The commencement certificate (CC) from the municipal authority must be uploaded. If the CC is absent or shows a different number of floors than what is being sold, the additional floors are illegal. Many buyers of Goregaon East and Malad West projects have faced this issue with high-rise towers.
5. Promoter Details and Litigation
The portal shows the promoter’s legal name, CIN number and any pending litigations. Cross-check the promoter name against the agreement for sale. If they are different entities, demand a written explanation. Also check if the promoter has other projects with MahaRERA complaints filed against them.
6. Bank Account Details
RERA requires 70% of all collections from buyers to be deposited in a dedicated project-specific escrow account. The portal shows the bank name and account number. Verify that your payments will go into this account, not any other. Ask the builder for the bank name and account number and match it against what is on the MahaRERA portal.
| Parameter | What to Look For | Risk if Missing |
|---|---|---|
| Registration Status | Must show Active | Builder has no legal right to sell |
| Completion Date | Future date or valid extension | Builder already in default |
| Commencement Certificate | Uploaded and matching floors | Illegal construction, flat may be demolished |
| Escrow Account | Dedicated project bank account | Funds diverted to other projects |
| Quarterly Progress | Updated within last quarter | Builder non-compliant with RERA reporting |
How to Verify a Real Estate Agent on MahaRERA
Under RERA, every real estate agent who sells or facilitates the sale of any RERA-registered project must themselves be registered with MahaRERA. An unregistered agent cannot legally receive a commission. If you are buying through an agent for a flat in Chembur, Mulund West or Borivali West, verify the agent before paying any brokerage.
To verify an agent, go to the MahaRERA portal and click “Registration” then “Agents”. Search by agent name or registration number. A valid agent registration will show the agent’s name, agency name if applicable, registration number (format A51900XXXXXX for Mumbai), registration validity date and contact details.
Insist that the agent’s MahaRERA registration number is mentioned in every document, including the booking form and brokerage agreement. This protects you legally if the transaction goes wrong. Reputable builders like Lodha Group, Godrej Properties, Rustomjee, Runwal Group and Kalpataru sell primarily through MahaRERA-registered agents.
MahaRERA Red Flags Every Mumbai Buyer Must Know
Beyond the basic verification steps, experienced buyers and lawyers in Mumbai watch for specific red flags that indicate a risky project. Here are the most important ones for buyers looking at 3 BHK flats across Mumbai.
Multiple MahaRERA Extensions
A project that has sought two or more extension requests on MahaRERA is in serious distress. While one extension is forgivable due to COVID or material shortage, multiple extensions signal cash flow problems. Check the extension history on the portal. Builders in Thane West and the extended MMR belt have been more prone to delays.
Complaints Filed Against the Project
You can view complaints filed against any project on MahaRERA. Use the “Complaint” section to search by project registration number. More than ten complaints for a mid-size project is a serious warning sign. Review what the complaints are about. Delay complaints are common but refund denial complaints indicate a builder who does not honour obligations.
Missing Quarterly Reports
Builders must upload quarterly progress reports every three months. If the last report is more than six months old, the builder is non-compliant. This is admissible evidence in a MahaRERA complaint hearing and reflects poor project management.
Discrepancy Between Marketed and Registered Units
Sometimes builders sell units that are not part of the RERA-registered phase. For example, a builder registers 200 units in Phase 1 but sells 250 units by including a Phase 2 that has no RERA registration yet. Always cross-check the tower name and unit number against the registered schedule of development.
No Occupancy Certificate for Completed Projects
For Lower Parel, Worli and Bandra West projects that claim to be ready for possession, verify the Occupancy Certificate (OC) on the portal. An OC is issued by the BMC or relevant municipal body and confirms the building is legally fit for occupation. Without an OC, you cannot get a home loan, register the flat, obtain utilities or get a society formed.
How to File a MahaRERA Complaint Against a Builder
If a Mumbai builder delays possession, refuses a refund or violates the registered sale agreement, you can file a complaint with MahaRERA online. The process is straightforward and does not require a lawyer, though legal assistance is advisable for complex cases.
Step 1: Register on the MahaRERA portal as a complainant. Use your Aadhaar-linked mobile number for OTP verification.
Step 2: Go to “Complaint Registration” and select the project registration number.
Step 3: Select the type of complaint from the dropdown: delay, refund, quality defect, false advertisement, etc.
Step 4: Upload supporting documents including the allotment letter, payment receipts, sale agreement and any correspondence with the builder.
Step 5: Pay the filing fee, which is Rs.5,000 for residential flat complaints as of 2026.
MahaRERA adjudicating officers are empowered to issue orders directing builders to pay interest, refund amounts or complete the project. MahaRERA orders are enforceable as civil court decrees. Buyers of Andheri West, Goregaon West and Dahisar projects have successfully recovered crores through MahaRERA orders in recent years.
Helpline and Contact
MahaRERA operates a helpline at 1800-XXXXXX (check the portal for the current number). The Mumbai office is at New Administrative Building, Bandra Kurla Complex, Mumbai 400051. For email support, use the contact form on maharerait.mahaonline.gov.in.

Frequently Asked Questions
How do I check if a Mumbai builder is registered on MahaRERA?
Visit maharerait.mahaonline.gov.in, click Registration then Projects, and search by promoter name or project name. Select Mumbai City or Mumbai Suburban as the district. A valid registration will show an Active status with a registration number starting with P51900. Always check this before paying any booking amount.
What does Active status on MahaRERA mean?
Active status means the project is currently registered, the registration has not lapsed and the builder is legally permitted to sell and collect money. If the status shows Lapsed, Revoked or Expired, the builder has no legal right to sell units and you should not proceed with any payment or agreement.
Can I file a MahaRERA complaint without a lawyer?
Yes. MahaRERA complaints can be filed online at maharerait.mahaonline.gov.in without any legal representation. You need to submit your allotment letter, payment receipts and sale agreement along with a Rs.5,000 filing fee. However, for large amounts or complex cases involving multiple violations, a lawyer experienced in RERA matters can significantly improve your chances of a favourable order.
What is the 70% escrow rule under MahaRERA?
Under RERA, builders must deposit 70% of all amounts collected from buyers into a dedicated escrow bank account that can only be used for construction of that specific project. This prevents builders from diverting flat buyers’ money to other projects or personal expenses. You can verify the escrow account details on the MahaRERA project page and ensure your cheques or bank transfers go to that account.
Is MahaRERA verification enough due diligence for buying a flat in Mumbai?
MahaRERA verification is essential but not sufficient on its own. You should also verify the title deed with a property lawyer, check the Occupancy Certificate for ready projects, verify the encumbrance certificate from the sub-registrar, and review the sale agreement carefully for penalty clauses. 3BHKFlat.com lists only MahaRERA-verified projects, which is your first and most important filter when searching for a 3 BHK flat in Mumbai.
