Builder Buyer Agreement Bengaluru: The Clauses Every Buyer Must Check in 2026

On 12 January 2026, the Karnataka Real Estate Regulatory Authority (K-RERA) confirmed it would start penalising builders who failed to file their mandatory annual audit reports, with a window of 20 January to 31 March 2026 to pay the penalty before recovery proceedings begin on 1 April 2026. The annual penalties run from 20,000 rupees for projects up to 25 crore rupees to 1,00,000 rupees for projects above 100 crore rupees. The same authority that polices these filings sets the model contract behind every builder buyer agreement Bengaluru buyers are handed, and most people sign that paper without reading it line by line.

The short answer. A builder buyer agreement Bengaluru buyers receive (also called the agreement for sale) is the contract that decides your possession date, your penalty for delay, your carpet area, and your refund rights. Under the Real Estate (Regulation and Development) Act 2016 (RERA), a promoter cannot collect more than 10 percent of the apartment cost before this agreement is signed and registered, and the rate of interest for delay is meant to be the same for both sides. The trade-off: the standard draft a builder hands you is written to favour the developer, so your only real leverage is to negotiate the clauses up front, before you pay.

Quick facts: on 12 January 2026 K-RERA announced annual penalties of 20,000 rupees to 1,00,000 rupees for builders who miss the audit-report deadline of 31 March 2026, per The Hans India.

What is a builder buyer agreement Bengaluru buyers sign, and why does it decide everything?

A builder buyer agreement Bengaluru buyers sign is the legally binding agreement for sale between you and the promoter that fixes the price, the apartment specification, the payment plan, the possession date, and the consequences if either side defaults. It is not the sale deed. The sale deed transfers ownership at the end, after possession; the agreement for sale is the promise that gets you there and protects your money meanwhile. For the full distinction, see our explainer on the difference between a sale agreement and a sale deed for Bengaluru buyers. Under Section 13 of RERA, the promoter cannot accept more than 10 percent of the cost of the apartment as an advance or application fee before this agreement is executed and registered. That rule is your first piece of leverage: until you sign, you owe at most 10 percent, so this is the moment to read and negotiate.

How should the possession date and delay penalty clause read?

The possession clause should state a specific calendar date for handover, not a vague phrase like "subject to force majeure and approvals." Under Section 18 of RERA, if the promoter misses the date in the agreement for sale, you have two rights. You can withdraw and claim a full refund of everything you paid, with interest. Or you can stay and claim interest for every month of delay until possession is handed over. K-RERA has enforced this in practice: in an order dated 2 January 2026, it directed Ozone Infra Developers to refund a homebuyer 19.87 lakh rupees with interest over a roughly four-year possession delay. The text of Section 18 sits alongside the carpet area definition in the RERA Act 2016 reference. Watch for the trick where the draft defines the "committed date" loosely or lets the builder reset the clock each time a new approval is sought. Push for a hard date and a clearly defined grace period in writing.

Why must the price be tied to carpet area, not super built-up area?

The price must be calculated on carpet area because RERA defines and mandates it. Section 2(k) of RERA defines carpet area as "the net usable floor area of an apartment, excluding the area covered by the external walls, areas under services shafts, exclusive balcony or verandah area and exclusive open terrace area, but includes the area covered by the internal partition walls of the apartment." In plain terms, carpet area is the usable space inside your walls, while super built-up area inflates that figure with shared lobbies and a share of common areas. Selling on super built-up area as the price basis is an unfair practice under RERA. Your agreement should quote the carpet area in square feet and the rate per square foot of carpet area. If the draft prices on "saleable" or "super built-up" area, ask for it to be restated on carpet area so you can compare projects honestly.

What does a fair payment schedule and construction-linked plan look like?

A fair payment schedule ties each instalment to a verifiable construction milestone, so you pay for work that has actually been done. This is the construction-linked plan, the buyer-side default to push for. Money is released at stages such as the foundation, each floor slab, and brickwork, rather than on fixed calendar dates regardless of progress. Compare this to a time-linked or upfront-heavy plan, where you pay large amounts early and carry the risk if the builder stalls. Remember the Section 13 backstop: no more than 10 percent before the registered agreement. After that, insist the schedule names the milestone for each demand so you can verify the stage before releasing funds.

What should the parking, amenities, and common-area clauses spell out?

The parking and amenities clauses should name exactly what you are buying and what is shared. Your agreement should specify the parking allotted to you and list the amenities the brochure promised, with the completion stage for each. Common areas belong to all allottees and the eventual owners' association, so check that the agreement does not let the builder sell or retain areas that should be common. Match the amenities list against the project's K-RERA registration on the Karnataka RERA project register, because what is registered is what the builder is bound to deliver. If the brochure shows a clubhouse or pool that the agreement does not commit to in writing, treat it as marketing, not a promise, and get the amenity into the contract.

Why does parity in the penalty clauses matter most of all?

Parity matters because the standard draft almost always punishes your delay harder than the builder's. A typical draft charges you a steep interest rate, sometimes 18 percent, if you are late with an instalment, while offering a token sum if the builder is late with possession. RERA was written to close this gap. State RERA rules, including the Karnataka framework, fix the interest payable by the promoter to the allottee and by the allottee to the promoter at the same level, benchmarked to the State Bank of India highest Marginal Cost of Lending Rate (MCLR) plus 2 percent. For context, SBI's one-year MCLR was 8.70 percent effective 15 January 2026, which shows why a symmetric clause protects you. So find the rate the builder charges you and the rate the builder pays you, and make them match. If they do not, that is the single clause most worth fighting over.

How do exit, cancellation, refund, and force majeure clauses protect you?

These clauses protect you only if they are specific, so read them assuming the builder drafted them to limit its own exposure. The cancellation clause should cap how much the builder can forfeit if you exit and set a clear timeline for returning the rest. The refund clause should state that on builder default, Section 18 entitles you to your money back with interest, not a slow or conditional return. The force majeure clause is where many builders quietly buy themselves unlimited delay, so it should list narrow events (such as natural disaster or a government order halting work), not routine causes like a labour shortage or a pending approval the builder should have secured. The trade-off to weigh: a buyer-friendly contract is harder to negotiate and may take longer to close, but a one-sided draft can cost you years and lakhs if the project stalls.

1. Confirm the agreement for sale is registered, and that you have paid no more than 10 percent of the apartment cost before signing, as Section 13 of RERA requires.
2. Check that the possession clause states a specific calendar date and a defined grace period, not an open-ended target.
3. Verify the price is calculated on carpet area as defined in Section 2(k), not super built-up or saleable area.
4. Insist on a construction-linked payment plan where each instalment is tied to a verifiable building milestone.
5. Make the interest rate for your delay and the builder's delay identical, benchmarked to SBI highest MCLR plus 2 percent.
6. Match the parking, amenities, and common-area promises against the project's K-RERA registration, and get every promised amenity in writing.
7. Read the cancellation, refund, and force majeure clauses for capped forfeiture, a refund timeline with interest, and a narrow list of genuine force majeure events.

Is the builder buyer agreement the same as the sale deed?

No. The builder buyer agreement, or agreement for sale, is the contract that fixes the price, possession date, and your rights during construction. The sale deed comes later and actually transfers ownership of the apartment to you after possession. The agreement for sale is what protects your money in the years between booking and handover.

How much can a builder collect before the agreement is signed?

Under Section 13 of the Real Estate (Regulation and Development) Act 2016, a promoter cannot accept more than 10 percent of the cost of the apartment as an advance or application fee before executing and registering the agreement for sale. This 10 percent cap is your leverage to read and negotiate clauses before paying more.

What interest can I claim if possession is delayed in Bengaluru?

Under Section 18 of RERA, if the builder misses the agreed possession date, you can withdraw and claim a full refund with interest, or stay and claim interest for every month of delay. Karnataka rules benchmark that interest to the State Bank of India highest Marginal Cost of Lending Rate plus 2 percent, the same rate that applies to your own delays.

Should the price be on carpet area or super built-up area?

The price should be on carpet area. Section 2(k) of RERA defines carpet area as the net usable floor area inside your walls, and pricing on super built-up or saleable area is treated as an unfair practice. Ask the builder to restate the rate per square foot on carpet area so you can compare projects on a true basis.
