Builder Buyer Agreement: Clauses to Check Before You Sign
Nobody reads the builder buyer agreement. Builders know this, and some of them write it accordingly.
We read these agreements for buyers every week, and the pattern repeats. Forty pages, signed in twenty minutes at the sales office, over tea. Then two years later the project runs late and the buyer discovers what page 23 actually said: the builder owes him ₹5 per square foot per month for the delay, while he owes the builder 18% interest for any late payment. He agreed to that. In writing.
So this is the guide we wish every buyer read the night before signing. It's not complicated. It's just ignored.
First, what this document is
When you book an under-construction flat, the builder buyer agreement, the BBA, becomes the rulebook of your entire purchase. Price, payment schedule, possession date, what happens when things go wrong. If there's ever a dispute, RERA and the courts read this document, not the brochure, not the WhatsApp messages from the sales guy. Verbal promises about the pool and the school? If they aren't in the BBA, they don't exist.
The clause that matters more than any other
The possession date. Find it. It must be an actual date, a month and a year, written plainly. Not "expected by", not "tentatively within 42 months of approvals". A vague date means no enforceable delay claim, and delay is the single most common thing that goes wrong in this market.
Right next to it, check the delay penalty. Under RERA the interest should cut both ways at the same rate: builder pays you for late possession exactly as you pay him for late instalments. When you see ₹5 per sq ft against your 18%, that's not a clause, that's a trap with a signature line.
Money clauses worth ten minutes of your life
The payment plan should be construction-linked. You pay as the slabs rise. A plan that front-loads 60-70% of the money before the structure is even up puts all the risk on you and none on the builder.
Then the price basis. RERA requires pricing on carpet area, the space you can actually walk on. If your agreement leans on a generous "super area", you're paying for the lobby and the gym lawn. Our carpet vs super area guide shows how big that gap gets.
And the extras. Club membership, covered parking, power backup, development charges, maintenance deposit. Ask for the all-in figure in writing before you sign anything. The buyers who don't ask meet these charges at possession, when refusing means losing the flat. Our cost breakdown guide lists every extra we've seen.
The quiet clauses that bite later
Force majeure. Fair in principle, floods and government bans do happen. But some builders draft it so widely that a labour shortage counts as an act of God. Read it and insist it covers genuine, unavoidable events only.
Termination and forfeiture. What happens if you miss one instalment? A fair clause gives you notice and time to cure. A harsh one cancels your booking and eats a fat slice of your money. Weigh it against what the builder suffers for his own delay. The two should look similar. They rarely do.
Layout changes. A clause letting the builder alter the plan or your unit's size "as required" can shrink what you bought. You want your consent required for any material change.
Transfer. Think you might sell before possession? Check the assignment clause and the transfer fee. We've seen fees high enough to lock buyers in completely.
One story, because it says everything
A client of ours, call him Anil, nearly signed a BBA promising possession "tentatively within 42 months" with that classic lopsided interest clause. His lawyer flagged both lines. The builder resisted, then agreed to a firm calendar date and matched interest rates. Two years later the project ran eight months late. Because of those two corrected lines, Anil collected real compensation instead of a token amount. The legal review had cost him a few thousand rupees. It returned lakhs.
How RERA backs you up
Most states now prescribe a model BBA under RERA, and it's your benchmark. Fair possession terms, carpet-area pricing, equal interest, sane cancellation rules. Put the builder's draft next to the model and every one-sided clause lights up. A builder in a registered project also can't take more than a small advance without a signed agreement, so nobody can rush you. Verify the registration first, five minutes on the portal, our RERA guide walks you through it.
After the signature
Keep the stamped copy safe. Pay only against construction stages, and keep every receipt and demand letter. If the possession date slips, record it in writing early, that paper trail is your claim. And at handover, ask for the occupancy certificate before you take the keys. Our OC guide explains why that last paper is worth holding the final payment for.
Frequently asked questions
What should I check in a builder buyer agreement?
Five things first: a firm possession date, an equal delay-interest clause, a construction-linked payment plan, carpet-area pricing, and the refund terms. Then the quieter clauses: force majeure, termination, layout changes, transfer fees.
Can I negotiate a builder buyer agreement?
Yes, and before signing is your only real moment of leverage. Builders push back, but clearly one-sided terms can also be challenged before RERA later. Easier to fix them now.
Is the BBA the same as the sale deed?
No. The BBA governs the booking and construction phase. The registered sale deed at possession is what actually transfers ownership. You'll sign both, at different stages.
What if the builder delays possession beyond the agreed date?
You're entitled to the delay interest written in the agreement, and RERA is the forum if he won't pay. This is exactly why the possession date must be firm and the interest clause equal.
Should a lawyer read the agreement before I sign?
On a purchase of fifty lakh or a crore, a few thousand rupees of legal review is the cheapest insurance you will ever buy. Yes.
Signing a BBA soon? Send it to us before you sign, not after, and we'll flag what needs fixing. Meanwhile our new launch listings carry projects whose paperwork we've already been through.
What is an occupancy certificate and why does it matter?
It certifies a building is legally fit to occupy. Never take possession of a completed home without it, since it affects loans, utilities and resale.
What is mutation and why is it important?
Mutation updates the ownership in municipal and revenue records after a sale. Without it the property tax and records still point to the old owner, so get it done.
What credit score do I need for a home loan?
Lenders prefer a healthy score, usually in the mid-700s and above, for the best rates. A lower score can still get a loan but often at a higher rate.
Can I claim tax benefits on a home loan?
Yes, home-loan principal and interest carry deductions under the income tax rules, subject to limits and conditions. Confirm the current rules or ask a tax adviser.
What is the difference between freehold and leasehold?
Freehold gives you full, permanent ownership of the property and land; leasehold runs for a fixed term from an authority. Freehold is generally simpler to resell.
How do I check a builder's track record?
Look at delivered projects, delivery delays, the RERA record and buyer reviews. A builder with a clean, on-time record lowers your risk sharply.
What red flags should I watch for when buying?
Unclear title, missing approvals or RERA, pending dues, a builder with delays, and prices far below the market. If something feels rushed, slow down and verify.
What is the difference between capital appreciation and rental yield?
Appreciation is the rise in the property value over time; rental yield is the annual rent as a share of the price. Most Indian homes give modest yield and rely on appreciation.
How much should I keep as a buffer beyond the price?
Set aside for stamp duty, registration, GST where it applies, interiors, and a contingency. A buffer of a meaningful share above the base price is prudent.
Is a home loan pre-approval useful?
Yes, a pre-approved loan tells you your budget, speeds up booking and strengthens your negotiating position with sellers. Get it before you shortlist seriously.
How do I choose between two similar projects?
Compare the builder record, RERA status, carpet area, real amenities, connectivity and total cost, not just the headline price. Visit both before deciding.
