When a Bengaluru family took possession of their flat in 2026 and found a persistent leak along a structural wall, they assumed the cost of fixing it was theirs. It was not. Under the law that now governs real estate, the developer was obliged to rectify a structural defect reported within five years of possession, at no cost to them. Most buyers never learn what the Real Estate Regulation and Development Act actually gives them until something goes wrong. Knowing your rights before you buy changes how you negotiate, what you insist on, and how confidently you can hold a developer to account.

The short answer. RERA gives homebuyers several concrete rights: you pay only for carpet area, the developer must fix structural or workmanship defects reported within five years of possession, you are entitled to interest or a refund if the project is delayed, and most of your money must sit in a separate project account. These rights are enforceable through the state regulator, faster than a civil court. The trade off is that you must know and assert them, because a right you do not invoke protects no one.

RERA is the Real Estate Regulation and Development Act, the national law that brought accountability to a sector long weighted against the buyer. It requires developers to register qualifying projects, disclose their plans and timelines, and follow rules designed to protect the people who fund construction with their savings. Before you can rely on these protections, the project must be registered, which is why verifying registration is the first step, covered in our guide to checking a Karnataka RERA registration. Once a project is registered, the Act gives you a set of rights that a developer cannot simply contract away, and understanding them is how you use the law rather than merely benefit from it by accident.

What is the carpet area pricing right?

RERA entitles you to be sold on carpet area, the usable floor space inside your apartment, rather than an inflated super built up figure. Carpet area is the space within your walls, excluding external walls, service shafts, balconies, and common areas. Before this rule, developers routinely quoted a larger super built up area that included a share of corridors and amenities, so buyers paid for space they could not use. By anchoring the sale to carpet area, RERA makes pricing comparable and honest across projects. When you compare two flats, comparing their carpet areas tells you what you are really buying, a point we expand in our guide to carpet area versus super built up area.

What is the five year defect liability?

RERA makes the developer responsible for structural and workmanship defects for five years from the date you take possession. If a defect in the building, such as a structural crack, a leak, or faulty work covered by the provision, appears within that period, the developer must put it right at no cost to you, and is expected to do so within a short window of being notified. This shifts the burden of early quality problems from the buyer to the developer, where it belongs, and it gives you a clear basis to demand repairs rather than paying for them yourself. Keep records of possession and of any defect you report, since dates and documentation are what make the right enforceable.

What are your rights if the project is delayed?

If the developer fails to hand over your home by the promised date, RERA gives you a choice. You can continue with the project and claim interest for every month of delay, or, where the delay is serious, seek to withdraw and obtain a refund of your money with interest. This right, which flows from the Act, is one of the most important protections a buyer has, because delayed possession was for years the single biggest grievance in the sector. The rate of interest is prescribed under the applicable rules, so confirm the current figure for your case. The essential point is that a delay is no longer simply your loss to absorb.

In practice, this right reshapes the balance of power during construction. A developer who knows that every month of slippage carries a cost is far more likely to keep to schedule and to communicate honestly about delays. As a buyer, you strengthen your position by keeping the promised possession date in writing, ideally in the registered agreement, and by noting the actual handover. If the two diverge, you have a documented basis to claim, rather than a vague grievance. The law gives you the right, but your own record keeping is what turns it into leverage you can actually use when it matters.

How does the separate project account protect your money?

RERA requires the developer to keep a large majority of the money collected from buyers, commonly described as seventy percent, in a separate account dedicated to that project. Those funds can be withdrawn only for the construction and land costs of the same project, not diverted to a different site or to the developer's other needs. For a buyer this reduces the classic risk that money paid for your tower quietly funds an unrelated project, leaving yours starved and stalled. It is not a guarantee against every problem, but it is a structural safeguard that did not exist before the Act, and it is one reason a registered project, bound by these financial rules, is safer than an unregistered one.

How do you enforce your RERA rights?

You enforce your rights by complaining to the state real estate regulator, not by suing in an ordinary civil court. The Act sets up an authority and an appeals process designed to resolve disputes within a defined timeframe, far faster than the years a civil case can take. You can file a complaint over a delay, a defect the developer refuses to fix, a deviation from the sanctioned plan, or a breach of the disclosed terms. Keep your agreement, payment receipts, possession records, and any correspondence, because a well documented complaint is far stronger. The regulator can direct the developer to comply, pay interest, or compensate you.

It helps to act early and in writing rather than letting a grievance fester. A polite but firm written notice to the developer, referencing the specific right and the relevant clause of your agreement, often resolves matters before a formal complaint is needed, and it also builds the record you would rely on if it is. Many buyers weaken their own case by raising issues only verbally, then struggling to prove what was promised. Treat every important exchange as something you may one day need to show the regulator, and you will find both the developer and the process far more responsive to a claim that is clearly documented from the start.

Your RERA rights checklist

Keep these seven rights and steps in mind as a buyer.

1. Confirm the project is RERA registered before you commit.
2. Insist that pricing is stated on carpet area, not super built up.
3. Record your possession date to start the defect liability clock.
4. Report any structural or workmanship defect in writing promptly.
5. Track the promised possession date and any delay against it.
6. Keep your agreement, receipts, and all developer correspondence.
7. File with the state regulator if the developer breaches your rights.

Where do you go to act on these rights?

Act on these rights through the state regulator and, where needed, a property lawyer familiar with RERA. Your protections rest on the project being registered in the first place, so confirm that before you commit, then keep the documentation that makes each right enforceable. The rights matter most at the moments buyers feel least powerful, when a handover slips or a defect appears, and they are only as strong as your willingness to invoke them. Whether you are buying a first flat or a larger home in a project such as Purva Hallmark on Kanakapura Road, these rights turn a hopeful purchase into a protected one, provided you know them going in and hold the paperwork to back them up.

Frequently asked questions

Do I have to pay for super built up area under RERA?

No. RERA entitles you to be sold on carpet area, the usable space inside your flat, rather than an inflated super built up figure that includes shared corridors and amenities. When you evaluate a flat, always ask for the carpet area, since that is the space you can actually use and the basis the law requires for the sale.

What happens if my builder delivers the flat late?

If the developer misses the promised possession date, RERA lets you either continue and claim interest for the delay, or, where the delay is serious, seek a refund with interest. The interest rate is set under the applicable rules, so confirm the current figure. The key point is that a delay is no longer only your loss to absorb.

How long is the developer responsible for defects?

Under RERA the developer is responsible for structural and workmanship defects for five years from the date of possession. If such a defect appears within that period, the developer must rectify it at no cost to you. Keep your possession record and report any defect in writing, since dates and documentation are what make the right enforceable.

How do I file a RERA complaint?

You file a complaint with your state real estate regulator rather than a civil court, which is designed to resolve disputes faster. You can complain about a delay, an unfixed defect, a deviation from the sanctioned plan, or a breach of disclosed terms. Keep your agreement, receipts, and correspondence, since a documented complaint is far stronger.
