Getting Less Carpet Area Than Promised

If you have been promised a certain carpet area in your society's redevelopment and worry the new flat may turn out smaller, the safest position is simple: only the RERA carpet-area figure written into your registered agreement is binding, and a developer cannot lawfully reduce it without the written consent of two-thirds of the allottees. Most carpet shortfalls are not sudden thefts of space — they grow quietly out of vague wording, confusion between carpet area and larger "saleable" numbers, and members signing before the promised area is fixed on paper. This guide explains, in plain language, how these shortfalls happen, the warning signs to watch for, concrete steps to protect every member, and the remedies available if you do receive less than you were promised.

What "carpet area" actually means under RERA

Under the Real Estate (Regulation and Development) Act, 2016 — usually called RERA, the law that regulates builders and flat sales in Maharashtra through MahaRERA — carpet area is the net usable floor space inside your flat: the area you could actually spread a carpet over. It is measured wall to wall within the flat and includes the thickness of the internal partition walls between your own rooms, but it excludes the external walls, the areas under service shafts, and any exclusive balcony, verandah or open-terrace space. Since RERA came into force, a flat must be described and sold on this carpet figure — not on the older, larger numbers builders once used.

Those older numbers still cause most of the confusion. Built-up area adds wall thickness and balconies on top of carpet. Super built-up or saleable area goes further, adding your flat's share of common spaces such as the lift, lobby, staircase and society office. The percentage a developer adds on top of carpet to reach these bigger figures is called the loading factor. A flat with 500 sq ft carpet and 30% loading might be marketed as 650 sq ft "saleable" — the very same home, a bigger-sounding number. In redevelopment, trouble starts when a member remembers the larger figure and receives the smaller, correct carpet figure, or when the offer never made clear which figure it was quoting in the first place. If any of these terms feel slippery, the plain-English FAQ & glossary sets each one out with an example.

Common ways a carpet-area shortfall creeps in

Very few shortfalls are dramatic. More often the space leaks away quietly between the first spoken promise and the final registered agreement. These are the patterns members most often report:

• Vague wording. The offer or memorandum of understanding says "area" or "flat size" without the word "carpet", leaving room to later argue it meant a larger figure.
• Carpet quoted against a larger base. A generous-sounding number turns out to be built-up, super built-up or saleable area, and the true carpet is much smaller once loading is stripped out.
• A loading factor that shifts. The loading percentage is left undisclosed, or it grows between the offer and the agreement, shrinking the carpet you actually receive.
• Offer and agreement disagree. The glossy offer letter shows one figure; the registered agreement quietly records a smaller one. The registered document is what binds — so the smaller figure wins.
• Plans without dimensions. The floor plan attached to the agreement carries no measurements, or the room sizes do not add up to the promised total.
• A "tolerance" clause. A clause lets the developer vary the area by a margin — say a few per cent — with no compensation, so a shortfall becomes "permitted".
• Balconies and shafts counted in. Balconies, dry balconies, flower beds, ducts or shaft areas are folded in to make the carpet look bigger than the usable floor really is.
• Verbal extras never written down. A promise of extra "incentive" area or a free enclosed balcony is made in a meeting but never enters the registered agreement.
• Show flat larger than reality. A sample or model flat is built roomier than the units members will actually be given.
• The delivered flat simply measures less. On a joint measurement after construction, the built flat is smaller than the agreement promised.

Warning signs and how to protect your society

Each warning sign has a straightforward protective step. Agree these as a society before signing anything, so no single member is left to argue about space alone.

How to protect every member — practical steps

1. Fix the number in writing, everywhere. The offer, the memorandum of understanding, the Development Agreement (the master contract between the society and the developer, often shortened to DA) and each member's Permanent Alternate Accommodation Agreement (the PAAA — the individual flat agreement that records exactly what each member will receive) must all state the same RERA carpet area, in square feet and square metres, in both figures and words.
2. Register the agreements. Under Section 17 of the Registration Act, 1908, the DA and PAAA must be compulsorily registered, and the Government's directive under Section 79A of the Maharashtra Co-operative Societies Act, 1960 (dated 4 July 2019) also requires DA and PAAA registration. A registered document carrying your carpet figure is your strongest proof. If your society has not yet begun, registering your society for guided support helps you get this right from day one.
3. Attach a dimensioned plan. Insist a signed floor plan with room measurements is annexed to the PAAA, so "500 sq ft carpet" is backed by dimensions that genuinely add up.
4. Check the developer's MahaRERA page. The project must be registered under Section 3 of RERA, and the carpet area the developer declares to MahaRERA should match the figure in your agreement.
5. Deal with tolerance clauses. Remove or tightly cap any clause that lets the area vary, and require compensation for any reduction rather than accepting it as "permitted".
6. Measure on the bare slab. Arrange a joint physical measurement by an independent architect or surveyor on the bare RCC slab, before tiling and plaster eat into the usable floor, and keep a video record. Read the flat wall to wall and compare it against the registered carpet figure.
7. Run the numbers independently. Use the Additional Area Calculator to check the extra carpet a project can genuinely offer, and the Offer Comparison tool to line up competing bids on a true carpet basis.
8. Get expert eyes on the draft. An independent tender and agreement review can catch loose "area" wording, missing dimensions and one-sided tolerance clauses before anyone signs — the same traps set out in our guide to common agreement mistakes.

If the area is reduced or you receive less than promised

RERA gives members real protection here. Under Section 14 of RERA, once the sanctioned plans and specifications are agreed, the developer cannot change them without the written consent of at least two-thirds of the allottees (the flat purchasers or members). A quiet, one-sided reduction in your carpet area is exactly the kind of change this section is meant to stop. RERA also carries a five-year defect-liability period under Section 14(3), so structural and workmanship defects noticed within five years of possession must be put right by the developer.

If a shortfall does occur, you are not without a remedy:

• Complain to MahaRERA. Under Section 31 of RERA, any aggrieved allottee — or the society acting on members' behalf — can file a complaint with MahaRERA against the developer for failing to deliver the promised carpet area.
• Approach the consumer forum. Delivering less than agreed is a deficiency of service under the Consumer Protection Act, 2019, which lets you claim compensation or a price adjustment for the missing area.
• Claim for delay too, where relevant. Where a shortfall comes alongside long delay, Section 18 of RERA lets allottees seek a refund with interest, or interest for every month of delay if they choose to continue with the flat.

Where a developer set out from the very beginning to promise space it never intended to deliver, that can amount to cheating under Section 318 of the Bharatiya Nyaya Sanhita, 2023 (the law that replaced the older Indian Penal Code); where money or property handed over in trust is later misused, Section 316 covers criminal breach of trust. These are serious criminal provisions that turn on proof of dishonest intent, so they are a last resort rather than a first step — but members should know the protection exists.
