For decades, Indian homebuyers were at the mercy of developers - endless delays, vanishing builders, and the bait-and-switch of super built-up area. The Real Estate (Regulation and Development) Act, 2016 (RERA) changed the balance of power. If you are buying or have bought an under-construction home, RERA is your strongest shield.
Mandatory project registration
RERA requires developers to register most projects with the state Real Estate Regulatory Authority before advertising or selling. Registration applies to projects above a certain size (commonly land area over 500 square metres or more than eight apartments). An unregistered project that should have been registered is a serious red flag - always verify registration on your state RERA website before paying anything.
The carpet-area rule
One of RERA's most consumer-friendly reforms is the mandatory use of carpet area - the actual usable floor area within the walls - for pricing and selling. Developers can no longer quietly inflate prices using super built-up area that includes lobbies, lifts, and shared spaces. You now pay for what you can actually use.
Protection of your money
To stop the rampant diversion of funds from one project to another, RERA requires the developer to deposit 70% of the amounts collected from buyers into a separate escrow account, to be used only for that project's construction and land cost. This keeps your money tied to your home.
Penalty for delayed possession
If the developer fails to hand over possession by the promised date, you have two options:
- Stay in the project and claim interest for every month of delay until possession; or
- Withdraw and demand a full refund of your money with interest.
Importantly, the interest rate payable by the developer to the buyer must be the same rate the developer would charge the buyer for a delay - ending the old one-sided contracts.
Liability for structural defects
The developer is liable to rectify any structural or quality defect brought to notice within five years of possession, free of cost, within 30 days. This addresses the common complaint of shoddy construction surfacing soon after handover.
How to file a RERA complaint online, step by step
Each state runs its own RERA authority and portal - for example, MahaRERA in Maharashtra at maharera.maharashtra.gov.in - but the flow is broadly the same everywhere. A complaint is filed under Section 31 of the Act against a registered project. Using MahaRERA as the model:
- Open your state RERA portal and click New Registration. Create an account with your name, email, phone, and password, and verify the OTP sent to your mobile.
- Log in and open the complaint form. Enter the project's RERA registration number, the promoter's details, and a clear statement of your grievance (delayed possession, plan alteration, or a quality defect).
- Upload your documents in the prescribed format - the agreement for sale, all payment receipts, the allotment letter, and your correspondence with the builder.
- Pay the fee online - for example, MahaRERA charges Rs. 5,000 per complaint.
- Submit. Both you and the promoter get an email notification and the complaint appears on each party's dashboard. You then attend hearings (often by video); RERA proceedings are designed to be far faster than a civil court.
Many states also offer a conciliation forum to settle the dispute through mediation before formal adjudication - worth considering for a quicker resolution.
If you are dissatisfied with the authority's order, you can appeal to the Real Estate Appellate Tribunal within the prescribed period.
Before booking any under-construction property, check three things on your state RERA site: the project registration number, the promised completion date filed with RERA, and any complaints already recorded against the developer.
What information must a developer disclose?
RERA forces transparency that simply did not exist before. For every registered project, the developer must upload and keep updated key details on the authority's website - the project plan and layout, the status of statutory approvals, the names of contractors and architects, the carpet area of units, and crucially the quarterly progress of construction. As a buyer you can track, from your phone, whether the project is actually progressing as promised, rather than relying on the sales office.
Agents must register too
It is not only developers - real estate agents who sell or facilitate the sale of units in a registered project must themselves be registered with RERA and quote their registration number. An unregistered agent peddling a project is another warning sign. This brings brokers, who were earlier completely unregulated, within the accountability net.
Penalties that give RERA teeth
RERA is not toothless. A developer who fails to register a project can be penalised up to 10% of the estimated project cost, and continued violation can attract imprisonment. Providing false information or breaching other provisions also carries monetary penalties. These real consequences are what changed developer behaviour, not just the promise of buyer-friendly rules on paper.
The limits of RERA
RERA is powerful but not a cure-all. It primarily governs registered, under-construction projects; very small projects and fully completed properties with a completion certificate fall outside its scope. For grievances that are purely about defective service, buyers sometimes also have parallel remedies under consumer law. And while RERA proceedings are faster than civil courts, outcomes still depend on the strength of your documentation - your agreement for sale, payment receipts, and written communications.
A buyer's pre-purchase checklist
- Verify the project's RERA registration number on the state portal.
- Confirm the carpet area and the price per carpet-area unit.
- Check the committed possession date filed with RERA.
- Read the agreement for sale carefully before paying.
- Confirm the selling agent is RERA-registered.
- Look up any existing complaints against the developer.
How to file a RERA complaint
If a developer breaches the agreement - delayed possession, a changed layout, or a quality defect - RERA gives buyers a direct forum. You file a complaint with your state's Real Estate Regulatory Authority, usually online, paying a nominal fee and attaching your agreement, payment receipts, and correspondence. Hearings are relatively quick compared with civil courts, and a lawyer is not mandatory. The Authority can order the developer to complete the project, hand over possession, refund money with interest, or pay compensation. Appeals go to the Real Estate Appellate Tribunal. For most homebuyers, this is a far faster and cheaper route than a regular civil suit.
Remedies for delayed possession
Delayed possession is the single most common grievance. Under RERA, if the developer fails to hand over the flat by the promised date, the buyer generally has two options: continue with the project and claim interest for every month of delay until possession, or withdraw and demand a full refund with interest. The interest rate is prescribed by the rules and is usually linked to a benchmark lending rate, so it is meaningful rather than token. Crucially, these rights flow from the registered agreement and the law, so a buyer is not at the mercy of one-sided clauses the builder may have inserted. Knowing this changes the negotiating position entirely.
Key takeaways
- Most under-construction projects must be RERA-registered - verify before you pay.
- Prices are based on carpet area, not super built-up area.
- 70% of buyer funds must sit in a project-specific escrow account.
- Delayed possession entitles you to interest or a full refund with interest.
- File complaints on your state RERA portal; appeals go to the Appellate Tribunal.
