Builder Collaboration Agreement in Delhi: Splits, Tax and Traps
An old plot in a Delhi colony is worth more demolished than standing. The builder knows it, and so the offer arrives: he pays for everything — demolition, sanction, construction, fittings — and in return keeps two of the four floors and pays you a lump sum on top. You move out for eighteen months and come back to a new building with your name on part of it.
Thousands of these deals close every year in South Delhi, West Delhi, Rohini and Dwarka. What decides whether yours works is a document most owners sign after reading it once.
Key takeaways
- The owner's share runs about 60% down to 35% of the built floors, and the lump sum swings from nothing to several crore. Colony, plot size and road width decide it.
- Delhi allows stilt plus four floors on plots above 50 sq m, capped at 17.5 metres. Without stilt parking, four storeys is the limit.
- A GPA does not transfer title. The Supreme Court settled that in Suraj Lamp in 2011 — the builder's buyer needs a registered sale deed, and you will have to sign it.
- Tax is deferred to the completion certificate under Section 45(5A), for individuals and HUFs, on a registered agreement. Sell your share earlier and the deferral is lost.
- TDS at 10% applies to the cash component under Section 194-IC, from the first rupee, with no threshold.
How a Delhi collaboration deal is put together
The structure is consistent even when the numbers are not. The builder funds demolition and reconstruction to an agreed specification, and on completion the built floors are divided in an agreed ratio, with cash moving from him to you to balance what each side receives.
On a standard plot the sellable units are the stilt parking, four residential floors and the terrace with the mumty. Five things to divide, and every one is negotiable. The owner typically also gets monthly rent for alternate accommodation during construction, plus a refundable security deposit at signing.
Two documents get executed: the collaboration agreement, which should be registered and stamped, and later, on completion, separate conveyances for the floors going to the builder's buyers.
The split, and what moves it
Nobody publishes this data. What follows is market practice as it stands in September 2026, and you should treat it as a band to negotiate within, not a rate card.
| Where the plot is | Owner's typical share | Lump sum to owner | Why |
|---|---|---|---|
| Prime South Delhi — Greater Kailash, Defence Colony, Vasant Vihar, Panchsheel | 50% to 60% of built floors | Rs 1 crore to Rs 6 crore | Land is the dominant cost and end prices are high; builders compete for plots |
| Mid South and West — Malviya Nagar, Rajouri Garden, Punjabi Bagh, Paschim Vihar | 40% to 50% | Rs 40 lakh to Rs 1.5 crore | Good end prices, more plots available |
| Outer colonies — Rohini, Dwarka, Janakpuri, Pitampura | 35% to 50% | Nil to Rs 40 lakh | Thinner margins; the cash often moves the other way on small plots |
| Unauthorised regularised and lal dora pockets | Highly variable | Usually nil | Title and sanction risk push the builder's required return up |
Four factors move you up that band. Plot size, because 300 sq yd yields far better unit sizes than 150 sq yd. Road width and corner status, which decide setbacks and saleability. Clean title rather than a GPA chain — read our guide to spotting fake property papers before you assume yours is clean. And whether the colony is authorised: a plot in a lal dora pocket attracts a very different deal from one in a DDA-approved colony a kilometre away.
Before negotiating, get the plot valued independently and price the builder's cost. Construction in Delhi at reasonable specification runs roughly Rs 1,900 to Rs 2,800 per sq ft of built-up area, plus sanction, demolition and finance. Knowing his outlay and the end price of a floor tells you what he can afford to give you.
What the agreement must nail down
- Floor allocation by name, not by formula. "First and third to the owner, second and fourth to the builder" — never "as mutually decided at completion".
- Stilt parking slots, the terrace and future FAR. These are frequently left blank and then claimed by the builder. Allocate all three explicitly.
- A dated completion timeline with a monthly penalty. Eighteen to twenty-four months is normal, and Rs 50,000 to Rs 1,50,000 a month past the date is what makes the date real.
- A specification schedule as an annexure. Brand and grade for flooring, fittings, wiring, lift, doors, waterproofing. "Best quality" means nothing in court.
- Who pays what. Sanction fees, labour cess, architect, demolition, new connections, and property tax during construction.
- Rent for alternate accommodation. Fixed, paid in advance, continuing until you physically get possession — not until "completion".
- Security deposit released only once the completion certificate is issued and the snag list is cleared.
- No sale of the builder's share before your floors are handed over. This one clause prevents most of the disasters in this format.
- Dispute resolution seated in Delhi, with a named arbitrator or institution.
The GPA problem
Builders routinely ask for a general power of attorney over the plot, to deal with the sanctioning authority and later to sell their floors. The first purpose is legitimate; the second is not.
In Suraj Lamp and Industries v State of Haryana, decided on 11 October 2011, the Supreme Court held that title to immovable property cannot pass by an agreement to sell, a general power of attorney or a will. Only a registered conveyance transfers title.
So if the builder sells a floor on a GPA-and-agreement basis, his buyer has no title and will eventually need a registered sale deed with you as signatory. Deal with it upfront: agree that conveyances of the builder's floors are executed by you in favour of his purchasers, on completion, at no cost to you, and not before your own floors are handed over. Keep the GPA limited to sanction and municipal work, and make it revocable.
Sanction, the fourth floor, and the completion certificate
Delhi's building bye-laws permit a stilt plus four residential floors on residential plots above 50 sq m, with total height capped at 17.5 metres. The stilt must stay open parking. Take away the stilt and the permissible count drops to four storeys.
That limit is enforced by sealing, and a sealing notice attaches to the property, not to the departed contractor. An owner whose builder squeezed in an extra floor is the one left holding a sealed building.
So insist on the sanctioned plan being annexed to the agreement, on construction matching it, and on the completion certificate at the end. For smaller Delhi plots the sanction route runs through empanelled architects with self-certification, which makes the paperwork faster and the temptation to skip it greater. Without a completion certificate you will struggle at resale and at loan stage — our comparison of an occupancy certificate versus a completion certificate explains which document does what. And when the floors are handed over, take a proper possession letter with a dated snag list attached.
Tax on the owner's share
Handing your land to a builder is a transfer, and it triggers capital gains. Section 45(5A) of the Income-tax Act, introduced by the Finance Act 2017 and effective from assessment year 2018-19, defers that liability.
The conditions are specific. You must be an individual or a HUF. The agreement must be a registered specified agreement. Where those are met, the capital gain is charged in the year the competent authority issues the completion certificate, in whole or in part, and the sale consideration is taken as the stamp duty value of your share on the date of that certificate plus any cash you received.
The trap is in the proviso. If you transfer your share in the project to anyone before the completion certificate is issued, the deferral falls away and the gain is taxed in the year of the original transfer, with interest running from then. Owners who book a sale of one of their floors during construction routinely walk into this.
Separately, Section 194-IC requires the builder to deduct TDS at 10% on any monetary consideration paid to you, from the first rupee, with no threshold. Without PAN it is 20%. That is on the cash component only — the value of the constructed area is not subject to this TDS, though it does count for capital gains.
What actually goes wrong
In rough order of frequency: the builder runs short of money at the finishing stage and the last 15% drags for a year. Specifications get quietly downgraded once your architect stops visiting. The completion date passes with no penalty because none was written in. His pre-sold buyers press you for conveyances before your own possession. An unsanctioned extra floor or covered stilt draws a notice. And the terrace, never allocated, turns out to be his.
Every one of those is a drafting failure, not bad luck. Spend Rs 50,000 on a property lawyer to draft the agreement and an independent architect to certify progress against the sanctioned plan at three stages. On a deal worth several crore, that is cheap insurance.
FAQ
What is a fair builder-owner ratio in Delhi?
There is no standard. In prime South Delhi colonies owners commonly hold 50% to 60% of the built floors plus a cash component; in outer colonies 35% to 50% with little or no cash is normal. Plot size, road width and title quality move the number more than negotiation does.
Should a collaboration agreement be registered?
Yes. It creates rights in immovable property and usually involves handing over possession. An unregistered development agreement is repeatedly treated as inadmissible in evidence, leaving you unable to prove the terms when you most need to.
Can the builder sell his floors before handing over mine?
Only if your agreement allows it, so do not allow it. Tie his right to market and convey his share to the handover of your floors.
Do I pay capital gains tax when I sign the agreement?
Not if you are an individual or HUF and the agreement is registered. Section 45(5A) defers the charge to the year the completion certificate is issued. Sell your share before that certificate and the deferral is lost.
How many floors can be built on a Delhi plot?
Stilt plus four residential floors on plots above 50 sq m, within a 17.5 metre height limit. Without stilt parking the limit is four storeys. Building beyond that invites sealing.
If a builder has put a term sheet in front of you, send it across before you sign — the clauses that decide the outcome are rarely the ones with numbers in them.
