What Is RERA and How It Protects Home Buyers

If you are about to book a flat from a builder, the first thing a good agent will tell you to check is the RERA number. But most buyers nod along without really knowing what RERA is, what it actually guarantees, and where its protection ends. This guide explains what is RERA in plain terms, how it protects home buyers, and the specific things you should verify before any money changes hands.

What is RERA, in one paragraph

The Real Estate (Regulation and Development) Act, 2016 created a regulator in every state, commonly called the RERA authority. Builders (called promoters) must register qualifying projects with it before advertising or selling, and property agents must register too. Once registered, the project's approvals, plans, timelines and promised specifications are on public record, and the builder is legally bound to them. If the builder breaks those promises, the buyer can complain to the authority instead of spending years in a civil court.

Each state runs its own portal and its own rules within the central framework, so details like fees, complaint procedure and interest rates differ. Always check your state's current rules.

The protections that actually matter to a buyer

Registration before sale

A builder cannot legally market or collect booking money for a covered project until it is registered. The registration number must appear on every advertisement, brochure and listing. When you see a flyer or an Instagram post for a new launch with no RERA number, that is your first red flag.

Carpet area, not super built-up

RERA requires builders to sell on carpet area, the usable floor area inside the walls, rather than vague super built-up figures. This is one of the biggest practical wins for buyers. If you are unsure how the three area terms differ, read our explainer on carpet area versus built-up and super built-up before comparing projects.

Your money sits in a project account

A large share of the money collected from buyers (typically around 70 percent) must be parked in a separate account for that project and can only be withdrawn for construction and land costs, with certification from professionals. This is meant to stop the old practice of using your booking money to buy land for the next project while yours stalls.

Fixed possession date with consequences

The completion date declared at registration is binding. If the builder misses it, the buyer can generally choose between continuing and receiving interest for each month of delay, or withdrawing and getting a refund with interest. The exact interest rate is set by state rules.

No changes to plans without consent

Once you have booked, the builder cannot materially alter the sanctioned plan, layout or specifications of your unit without your written consent, and cannot alter common areas without consent from a majority of allottees.

Defect liability

If structural or workmanship defects show up within five years of possession, the builder must fix them at no cost within a defined period. Keep your handover documents and photos from the day you took possession.

A faster complaint route

Complaints go to the state authority or its adjudicating officer, with appeal to an appellate tribunal. It is not instant, but it is designed to be far quicker and cheaper than a civil suit.

Where RERA does not protect you

Being honest about the limits is part of the job.

• Unregistered or exempt projects. Projects below the area or unit threshold, and some projects completed before the Act took effect, may not be covered.
• Resale between individuals. If you are buying a flat from another owner, RERA is largely irrelevant. Your protection comes from title checks, society NOC and the sale deed. Our resale flat buying guide covers that process.
• Quality beyond the spec. RERA holds the builder to the specifications declared. If the brochure said "vitrified tiles" and you expected Italian marble, that is a disappointment, not a violation.
• Enforcement speed. Orders can still take time to execute. RERA improves your odds; it does not remove the need for due diligence.

A 20-minute RERA check before you book

Do this on your phone while you are still at the site office.

1. Find the registration number on the brochure or ask for it. Refusal or "it's in process" means do not pay anything yet.
2. Search it on the state RERA portal. Confirm the project name, the promoter's legal name and the exact tower or phase. Builders often register phases separately; make sure your tower is in the registered phase.
3. Check the declared completion date. Compare it with what the sales team told you verbally. A six-month gap is common; a two-year gap is a warning.
4. Open the sanctioned plan and approvals. Look for the layout approval, building plan approval and land title documents uploaded to the portal.
5. Read the quarterly progress updates. Registered projects must update construction status. Stale or missing updates tell you something about the builder's discipline.
6. Look for complaints and orders against the promoter on the same portal.
7. Check the agent's registration too. A registered agent has a RERA number of their own and is accountable for what they tell you. If you are an agent reading this, putting your number on your profile is one of the cheapest trust signals available; we cover that in why showing your RERA number builds trust.

Documents to keep from day one

• The allotment letter and the builder-buyer agreement in the state's model format
• Every payment receipt, with the project account details
• Screenshots of the RERA portal page on the date you booked
• The brochure and specification sheet you were shown
• All emails and WhatsApp messages about timelines or changes

If a dispute ever arises, the buyer with a tidy folder wins far more often than the buyer relying on memory.

Questions to put to the builder, in writing

Ask these over email or WhatsApp so you have a record.

• What is the RERA registration number for my specific tower or phase?
• What is the declared completion date on the portal, and is there any revision application pending?
• What is the carpet area of my unit as per the registered plan?
• What happens to my payments if the project is delayed beyond the declared date?
• Are there any pending approvals (environment, fire, occupancy) and who is responsible for them?

Good builders answer these without hesitation. Evasive answers are information too. For a longer list, see our article on questions to ask a builder before booking a flat.

A note for agents sharing this with clients

Explaining RERA calmly is a competitive edge. Buyers remember the agent who told them to check the portal rather than the one who pushed for a token amount on the spot. Many agents now put a short "verified checks" line on each property page they share, listing the RERA number, the possession date and the carpet area, so the buyer sees it before the first call. If you run your own pages, a tool like My Property Pages lets you put those details and your own RERA number on a page per listing, with enquiries coming straight to you.

Frequently asked questions

Does RERA apply to every property I might buy?

No. It covers projects above a size threshold that are registered with the state authority, and registered agents. Small projects, many resale deals between individuals and some older completed projects fall outside it, so check the status of your specific project.

How do I check a project's RERA registration?

Go to your state RERA portal, search by project name or registration number, and compare the promoter name, approved plans, completion date and quarterly updates with what the builder told you.

What can I do if the builder delays possession?

Under RERA you can generally seek interest for the delay or withdraw with a refund plus interest, by filing a complaint with the state authority. Rates and procedure vary by state, so check your state's current rules.
