What Is RERA and How Does It Protect Home Buyers?

If you've bought a flat in India in the last few years, you've probably seen a RERA number printed in small type at the bottom of an advertisement or on the first page of your agreement. Most buyers don't think about it again until something goes wrong. Then they discover that those four letters stand for one of the most important consumer laws the country has passed for ordinary families.

This guide explains, without legal jargon, what RERA is, why it was needed, what it changed, and how you can use it. If you're about to buy, it tells you what to check. If you've already bought and your builder is late, it tells you what you can do.

What RERA stands for

RERA is short for the Real Estate (Regulation and Development) Act, 2016. People also use "RERA" to mean the regulator each state has set up under the Act, so you'll hear phrases like "UP RERA" or "Haryana RERA" for the authorities in those states. Parliament passed the Act in 2016, and its main provisions came into force on 1 May 2017. Every state then made its own rules and set up its own authority.

So when someone says "file in RERA", they mean filing a complaint with the real estate regulatory authority of the state where your project is.

Why the law was needed

Before 2017, buying an under-construction flat was largely a leap of faith. A typical buyer paid a booking amount, signed a long agreement drafted entirely by the builder, and then paid instalments for years while construction crept along. Common problems included:

• Endless delay, with the possession date pushed back again and again, and token compensation of a few rupees per square foot if any.
• One-sided agreements, where the buyer paid 18% or 24% interest for a late instalment but the builder paid almost nothing for years of delay.
• Money diverted from one project to buy land or fund another, so that the buyer's own tower ran out of money.
• "Super area" pricing, where buyers were charged for an inflated area that included a share of lobbies and corridors, and only discovered how small the actual flat was at possession.
• Plan changes without the buyer's knowledge: an extra tower in the park, a smaller clubhouse.
• No single regulator. Buyers had to go to consumer courts or civil courts, which took years, with no body watching projects as they were built.

The NCR felt all of this more than anywhere. Hundreds of projects launched between 2008 and 2014 in Noida, Greater Noida, Gurugram and Ghaziabad ran years late, and some never finished. RERA was Parliament's response.

The big idea: transparency plus a regulator

RERA does two things at once. It forces developers to put information about their projects in public, so that buyers can see what they're buying. And it creates a specialised regulator in every state with real powers to punish developers who break the rules and to give buyers quick remedies.

Those two ideas run through every part of the Act.

Which projects RERA covers

Under Section 3, a real estate project must be registered with the state authority before the developer can advertise, market, book, sell or offer any unit in it. That applies to new projects and to projects that were already under construction on 1 May 2017 without a completion certificate. The Supreme Court confirmed in Newtech Promoters and Developers v. State of UP (2021) that the Act applies to such ongoing projects, including agreements signed before 2017.

There are some exemptions. Registration isn't required where:

• the land doesn't exceed 500 square metres, or the number of units doesn't exceed eight, counting all phases (states can set lower limits);
• the developer received a completion certificate before the Act came into force; or
• the work is renovation or repair that doesn't involve marketing or selling new units.

RERA covers residential and commercial projects, flats and plots alike. Shops, offices and plotted colonies are as much covered as apartment towers. It also covers real estate agents, who need their own registration.

So a small builder floor on a 300 square metre plot in Delhi probably isn't covered, but a 400-flat society in Noida or a 50-plot colony near Jaipur almost certainly is. See our guide on checking RERA registration.

What developers have to do

RERA puts a long list of duties on the "promoter", the Act's word for the developer (and sometimes the landowner too). The most important ones for buyers:

Register and disclose

The developer must register the project and upload its details: approvals, layout and building plans, the land title, the number and carpet area of units, the declared completion date, the names of architects and contractors, and more. All of this goes on a public web page for the project on the authority's website.

Update every quarter

Every quarter, the developer must update the project page with bookings, approvals received and construction progress. If your builder says the tower is "almost done" but the RERA page shows 40% progress, you know which to believe.

Keep 70% of your money in the project

Under Section 4(2)(l)(D), 70% of the money collected from buyers must go into a separate bank account and be used only for that project's land and construction. Withdrawals have to be certified by an engineer, an architect and a chartered accountant, and the account must be audited every year. This is the rule meant to stop money being diverted to other projects.

Sell on carpet area

Units must be sold on the basis of carpet area, defined in Section 2(k) as the net usable floor area inside the walls, plus a few defined items. No more pricing on vague "super area".

Take no more than 10% before the agreement

Under Section 13, the developer can't take more than 10% of the price as an advance or booking amount before signing a registered agreement for sale.

Stick to the plans

Under Section 14, the developer must build according to the sanctioned plans. Changes to your unit need your written consent, and changes to the building or common areas need the consent of at least two-thirds of the buyers.

Fix defects for five years

Under Section 14(3), structural defects and defects in workmanship, quality or services that you report within five years of possession must be fixed by the developer within 30 days, free of charge. If not, you're entitled to compensation.

Hand over properly

The developer must obtain the completion or occupancy certificate, help form the residents' association, execute your conveyance deed, and hand over the common areas and documents to the association.

Your rights as a buyer

RERA calls the buyer an "allottee". Section 19 sets out allottees' rights, and other sections add remedies. In everyday terms, you have the right to:

• Information about the sanctioned plans, layout, specifications and the stage-wise schedule of completion.
• Know the timeline and get possession on the date in your agreement.
• Get your money back with interest if the developer fails to give possession on time and you want to leave the project, or get interest for every month of delay if you want to stay. This is Section 18, the provision most buyers use.
• Compensation for loss caused by false information in advertisements, defects, delay or other breaches.
• Get the documents: the occupancy certificate, the conveyance deed, and for the association, the plans and common area documents.
• Complain to the authority about any violation of the Act, the rules or the regulations, under Section 31.

The interest rate isn't left to argument. Each state's rules fix it. In UP, Haryana and many other states, it's the State Bank of India's highest marginal cost of lending rate plus 2%. Crucially, the same rate applies when you're late paying the developer. The days of 18% for the buyer and almost nothing for the builder are over. See our guide on the interest on RERA refunds.

Your duties, too

RERA isn't one-sided in the other direction. Section 19 also makes buyers responsible for paying on time, paying interest at the same prescribed rate if they're late, taking possession within two months of the occupancy certificate, and participating in forming the association. A buyer who stopped paying instalments years before the builder ran late may find that affects the claim. It's worth knowing both sides before you file.

How a RERA complaint works, in brief

1. Collect your papers: agreement, receipts, bank statements, letters from the builder. See our guide on documents for a RERA complaint.
2. File online with the authority of the state where the project is, with the prescribed fee.
3. Attend hearings, often online. The builder files a reply, and the authority hears both sides.
4. Get an order, usually for a refund with interest or monthly delay interest, and directions about possession or charges.
5. Enforce it if the builder doesn't pay: the amount is recoverable as arrears of land revenue, through the district administration. See our guide on when the builder doesn't pay.

Compensation for things like rent you paid while waiting, or harassment, is claimed separately before the authority's adjudicating officer, following the Supreme Court's decision in Newtech. How long all this takes depends on the authority and whether the builder contests. See how long a RERA complaint takes.

The appeal ladder

Either side can appeal an authority's order to the state's Real Estate Appellate Tribunal within 60 days, and then, on a question of law, to the High Court. One rule matters a lot to buyers: a developer that wants to appeal must first deposit the full amount ordered in the buyer's favour (or at least 30% of any penalty) with the tribunal. That stops builders from appealing just to delay payment. See the pre-deposit rule.

What RERA hasn't fixed

RERA has made a real difference, but it would be wrong to pretend it solved everything. Some honest limits:

• It can't create money that isn't there. If a developer has spent buyers' money and has no assets, an order for a refund may take a long time to recover. Many NCR buyers hold orders that haven't been paid.
• It doesn't control the development authorities. In Noida and Greater Noida, registries were blocked for years because developers owed land dues to the authorities. RERA can direct the developer, but it can't waive what the land authority is owed.
• It doesn't cover everything. Small builder floors, houses in unauthorised colonies, and plots sold on agricultural land with no approvals often fall outside it.
• Enforcement varies by state. Some authorities are quicker and more active than others.
• Insolvency changes the picture. When a developer is taken into insolvency, RERA proceedings generally stop, and buyers' claims go into the insolvency process. See our guide on builder insolvency.

Even so, a buyer today is far better placed than a buyer in 2012. The information is public, the interest rate is fixed, the regulator is specialised, and the developer can't sit on an order and appeal for years without paying.

RERA or consumer court?

RERA didn't replace the consumer courts. The Supreme Court held in Imperia Structures v. Anil Patni (2020) that buyers can choose either. RERA is usually faster and more predictable for refund and delay claims; the consumer commission can suit buyers with large compensation claims or who want to file where they live. You shouldn't pursue the same claim in both at once. See our guide on RERA or consumer court.

What to check before you buy

• Search the project on the state authority's website using the registration number in the advertisement. If there's no number, be very careful.
• Read the project page: the declared completion date, the approvals uploaded, and the quarterly progress updates.
• Check the carpet area of your unit in the agreement.
• Pay no more than 10% before a registered agreement for sale.
• Make sure payments go into the account named in the agreement.
• Check the developer's record: complaints and orders against it on the authority's website.
• If buying through an agent, check that the agent is registered too.

See our agreement review service if you'd like a lawyer to look at the documents before you sign.

Is RERA the same in every state?

The Act is the same everywhere, but the details aren't. Each state makes its own rules and regulations, which set things like the complaint form and fee, the interest rate, the format of quarterly updates and annual audits, and sometimes extra protections. Haryana, for example, uses separate complaint forms for the authority and for compensation claims, and the Gurugram authority issued regulations capping how much a builder can forfeit when it cancels a booking. Uttar Pradesh recovers unpaid orders through recovery certificates sent to district magistrates. Maharashtra runs a conciliation forum for voluntary settlements.

Some states also have more than one authority. Haryana has one in Gurugram for Gurugram district and another in Panchkula for the rest of the state. And the authority that handles your case is the one for the state where the project is, not where you live. A Delhi resident with a Noida flat goes to UP RERA. See our pages on UP RERA and Haryana RERA Gurugram.

Advertising and agents

RERA changed how property is sold, not just how it's built. Every advertisement for a registered project must carry the registration number and the authority's website address. A developer can't advertise a project that isn't registered. And under Section 12, if you paid on the strength of false information in an advertisement or brochure and suffered loss, the developer must compensate you, and you can withdraw from the project with a refund and interest.

Agents, brokers and channel partners who deal in registered projects must register with the authority too, keep proper records, and not misrepresent the project. If an agent promised you things that turned out to be untrue, that can matter in a later complaint. Keep the brochures, emails and messages you receive while buying. See agent registration.

What RERA means for a developer

For honest developers, RERA is mostly about discipline: register before selling, keep the project account clean, file updates on time, stick to the plans, and deliver what was promised. Those who do find that buyers trust them more and that disputes, when they happen, are easier to resolve. Those who don't face penalties of up to 10% of the project's estimated cost for selling without registration, up to 5% for most other violations, daily penalties for ignoring orders, and in the worst cases revocation of the project's registration. See our page on compliance for builders.

If you remember only five things

1. Check the RERA registration before you pay anything.
2. Never pay more than 10% before a registered agreement for sale.
3. If the builder is late, you can choose between a refund with interest and monthly delay interest.
4. Report defects in writing within five years of possession; the builder must fix them within 30 days.
5. If the builder doesn't pay an order, the district administration can recover it like a land revenue debt.

Keep a folder with every document and payment record from the day you book. Almost every RERA case is won or lost on paper.

A short example

Here's a made-up example that shows how the pieces fit together. Meera booked a 2BHK in a Gurugram project in 2014. The agreement promised possession by 2018 and offered "Rs 5 per square foot per month" as compensation for delay, while charging 18% interest on any late instalment. By 2023 the tower still wasn't finished.

Before RERA, Meera's options would have been a consumer case or a civil suit, with a long wait and an uncertain result. Instead, she checks the project on the Haryana RERA Gurugram website, sees from the quarterly updates that progress has been slow for years, and files a complaint. She asks to stay in the project and claim delay interest.

The authority ignores the token compensation clause. The project was ongoing in 2017, so the Act applies to her older agreement. It orders interest at the prescribed rate on everything she paid, for every month from the due date until a valid offer of possession after the occupancy certificate. When the developer appeals, it has to deposit the interest first. When the flat is finished, the interest owed to her is adjusted against her last instalment.

The law didn't make the tower go up faster. But it made the delay expensive for the developer and gave Meera a fair, predictable remedy.

Words you'll meet

• Promoter: the developer, and in some cases the landowner, who builds and sells the project.
• Allottee: you, the buyer, including someone who bought from the original buyer with the developer's endorsement.
• Carpet area: the usable area inside your flat's walls.
• Occupancy certificate (OC): the authority's certificate that the building can be lawfully occupied.
• Adjudicating officer: the officer who decides compensation claims.
• Appellate Tribunal: the body that hears appeals from the authority.

There are many more. Our RERA glossary explains them in plain English.

Frequently asked questions

What is the full form of RERA?

The Real Estate (Regulation and Development) Act, 2016. The term is also used for each state's Real Estate Regulatory Authority set up under the Act.

When did RERA come into force?

The main provisions came into force on 1 May 2017. States then notified their own rules and set up their authorities.

Does RERA apply to my flat if I booked before 2017?

Yes, if the project was still under construction without a completion certificate in 2017. The Supreme Court confirmed this in Newtech (2021).

Does RERA cover plots and shops?

Yes. It covers plots, apartments, buildings and commercial units in registered projects.

What can I get if my builder is late?

A refund with interest if you want to leave, or interest for every month of delay if you want to stay, at the rate fixed by your state's rules.

Is RERA better than consumer court?

For most refund and delay claims it's faster and more predictable, but the choice is yours, and consumer court can suit some cases better.

Can a builder ignore a RERA order?

It can try, but the amount can be recovered as arrears of land revenue, daily penalties can be imposed, and the builder can't appeal without first depositing the amount.

Do I need a lawyer to file a RERA complaint?

Not legally. Many buyers file themselves. A lawyer helps with calculations, documents, contested hearings and enforcement.
