Take a Tape to Your Handover: Checking a Bengaluru Flat's Carpet Area Against RERA
Section 2(k) of the RERA Act defines carpet area, Section 4(2)(h) makes promoters disclose it with balcony and terrace areas, and Section 14 ties construction to sanctioned plans. This guide shows how a Bengaluru buyer can measure carpet area at handover, with a worked example and a checklist.
Handover day in a new Bengaluru apartment can run on a checklist of switches, taps and tiles. A tape measure may not be on it. Yet the number at the centre of the sale, its carpet area, is something an owner can check with a tape, a notebook and an hour of patience, using a definition written into the Real Estate (Regulation and Development) Act, 2016.
This guide explains what the Act counts as carpet area, what it leaves out, where the promised figure is recorded, and how to compare it with the flat you are handed.
The short answer. Section 2(k) of the Act defines carpet area as the net usable floor area of an apartment, excluding the area covered by the external walls, areas under service shafts, exclusive balcony or verandah area and exclusive open terrace area, but including the area covered by the internal partition walls. Section 4(2)(h) requires the promoter to disclose, at registration, the number, type and carpet area of apartments along with the areas of exclusive balconies or verandahs and open terraces. Section 14(1) requires the project to be completed as per the sanctioned plans and specifications. The trade-off: measuring takes effort and some care with walls and balconies, but it is the only way to know the number you paid for is the number you got.
What does RERA count as carpet area?
The usable floor inside the flat, plus internal walls. In the text of the Act published by the Telangana regulator, Section 2(k) 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 including the area covered by the internal partition walls of the apartment.
The Explanation to the clause defines the two outdoor terms. Exclusive balcony or verandah area means the area of the balcony or verandah which is appurtenant to the net usable floor area of an apartment, meant for the exclusive use of the allottee. Exclusive open terrace area means the area of open terrace which is appurtenant to the net usable floor area, meant for the exclusive use of the allottee.
So a bedroom wall that separates two rooms inside the flat counts. The outer wall of the building does not. A balcony that only you can use does not count in carpet area, but it is not ignored either, as the next section shows.
| Part of the flat | In carpet area? | Basis |
|---|---|---|
| Net usable floor of rooms, kitchen, toilets and passages inside the flat | Yes | Section 2(k) |
| Internal partition walls of the apartment | Yes | Section 2(k) |
| External walls | No | Section 2(k) |
| Areas under service shafts | No | Section 2(k) |
| Exclusive balcony, verandah or open terrace | No, but disclosed separately at registration | Sections 2(k) and 4(2)(h) |
Where is the promised figure recorded?
In at least three places a buyer can check. First, the registration filing. Section 4(2)(h) requires the promoter to enclose with the registration application the number, type and the carpet area of apartments for sale in the project, along with the area of the exclusive balcony or verandah areas and the exclusive open terrace areas with the apartment, if any. Section 4(2)(i) separately requires the number and areas of garages for sale.
Second, the regulator's website. Section 11(1) says the promoter shall create its web page on the Authority's website and enter all details of the proposed project as provided under Section 4(2), in all the fields provided, for public viewing.
Third, your own agreement. Section 13(2) says the agreement for sale shall specify the particulars of development of the project, including the construction of building and apartments, along with specifications. Look for the carpet area of your unit in the agreement's description of the apartment. Our earlier report on carpet, built-up and super built-up area in Bengaluru explains how the other area terms in brochures relate to it.
How do you measure it at handover?
Room by room, inside face to inside face, then add internal walls. A practical method that follows the Section 2(k) definition looks like this. Measure the length and breadth of each room, the kitchen, each toilet and each passage from the inside face of one wall to the inside face of the opposite wall, and multiply. Add them up. Then add the area under the internal partition walls, which the definition includes. Leave out the balcony, any exclusive terrace, any service shaft and the external walls.
A worked example shows the arithmetic. Suppose a two-bedroom flat measures: living and dining 15 by 12 feet, which is 180 square feet; bedroom one 12 by 11, which is 132; bedroom two 11 by 10, which is 110; kitchen 10 by 8, which is 80; two toilets of 8 by 5 and 7 by 5, which are 40 and 35; and a passage of 12 by 3.5, which is 42. Those add up to 619 square feet. If the internal partition walls cover a further 25 square feet, the carpet area by the Section 2(k) method is 644 square feet. That is the figure to compare with the one in your agreement.
Internal walls are the fiddly part. One way is to measure the thickness of each internal wall and its length, and multiply. Another is to ask the builder for the measured drawing of your unit and check the internal wall areas against it. Either way, write down every measurement, because a dispute later turns on records, not memory.
Where do parking and garages fit?
Outside carpet area, and disclosed separately. Section 4(2)(i) requires the promoter to file the number and areas of garages for sale in the project, apart from the carpet area of apartments under Section 4(2)(h). Open parking is treated differently again. Section 2(n)(iii) lists open parking areas among the common areas, along with common basements, terraces, parks, play areas and common storage spaces.
For a buyer, this means three numbers to keep apart: the carpet area of the flat, the area of any exclusive balcony or terrace, and the details of any garage or parking space allotted. If the agreement or allotment letter bundles them into one figure, ask the builder to show each separately, the way the registration filing is required to.
What if the flat is smaller than promised?
Start with the agreement, then the Act. Section 14(1) says the proposed project shall be developed and completed by the promoter in accordance with the sanctioned plans, layout plans and specifications as approved by the competent authorities. Section 14(2)(i) says that once the sanctioned plans and specifications of the apartment have been disclosed to the buyer, the promoter shall not make additions or alterations to them without the buyer's previous consent. Its proviso allows minor additions or alterations required by the allottee, or minor changes necessary for architectural and structural reasons, duly recommended and verified by an authorised architect or engineer after proper declaration and intimation to the allottee.
The Explanation narrows what counts as minor. It says minor additions or alterations exclude structural change including an addition to the area or change in height, or the removal of part of a building, or any change to the structure such as the construction or removal or cutting into of any wall or a part of a wall, partition, column, beam, joist or floor.
A buyer who finds a meaningful gap can raise it in writing with the promoter, citing the agreement's figure and the Section 2(k) measurement. If it is not resolved, Section 31(1) lets any aggrieved person file a complaint with the Authority or the adjudicating officer for any violation of the Act. Section 18(3) says that if the promoter fails to discharge any other obligations under the Act or the agreement for sale, it shall be liable to pay compensation to the allottees in the manner provided under the Act.
Before booking in any project, for instance one such as Sumadhura Solea in Rachenahalli, compare the unit's carpet area in the agreement with the figure shown for that unit type on the regulator's project page.
What should you take to the handover?
A tape, the paperwork and a plan. Use this list.
- Carry your agreement for sale, with the carpet area and specifications of your unit marked.
- Print the unit type's carpet area and balcony area from the project's page on the regulator's website.
- Ask the builder in advance for the measured drawing of your flat, showing internal wall thickness.
- Measure each room, the kitchen, toilets and passages from inside face to inside face.
- Add the internal partition wall area, and leave out balconies, exclusive terraces, service shafts and external walls.
- Note any shortfall against the agreement in writing to the builder on the day, with your measurement sheet.
- Keep the sheet with the possession letter; our Bengaluru handover checklist covers the other items to inspect.
Frequently asked questions
Does carpet area include the balcony under RERA?
No. Section 2(k) of the RERA Act excludes the exclusive balcony or verandah area and the exclusive open terrace area from carpet area. These are not ignored, though. Section 4(2)(h) requires the promoter to disclose the areas of exclusive balconies, verandahs and open terraces separately, along with the carpet area of each apartment.
Are internal walls part of carpet area?
Yes. Section 2(k) defines carpet area as the net usable floor area of an apartment, and it expressly includes the area covered by the internal partition walls of the apartment. It excludes the area covered by the external walls and areas under service shafts, so only the walls inside the flat are counted.
Where can I find the carpet area the builder declared?
Section 4(2)(h) requires the promoter to file the number, type and carpet area of apartments with its registration application, and Section 11(1) requires it to enter the Section 4(2) details on the Authority's website for public viewing. Your agreement for sale should also specify the particulars of your apartment.
Can the builder reduce my flat's area after I book?
Section 14(2)(i) says the promoter shall not make additions or alterations to the disclosed sanctioned plans and specifications of your apartment without your previous consent. Minor changes for architectural or structural reasons are allowed after declaration and intimation, but the Explanation says minor changes exclude structural change, including an addition to area.
