Must know provisions under RERA Act 2016 (June 2022)

Land is an essential natural resource, both for the survival and prosperity of humanity and for the maintenance of all terrestrial ecosystems. Over millennia, people have become progressively more expert in exploiting land resources for their own ends. The limits on these resources are finite while human demands on them are not!

Over the years, the movement of humans from small places to cities made the concentration of humans in a limited place/city/locality results in the vertical development of buildings. The vertical development of buildings can be called Apartment complexes.

The shift from individually owning land to common ownership of land (under group housing schemes) calls for common rights, responsibilities, and continuity of common ownership of the property. Even though the concept of group housing exists since 1970’s, the actual and real challenges are not experienced unless the redevelopment stage is reached.

The increasing trend of human greed, narrowing the trust, ethics and loyalty factors in the business environment leads to uncertainty among various stakeholders. To bring certainty and protect the stakeholders, the government brought a policy by way of statute. The state government has enacted THE KARNATAKA OWNERSHIP FLATS (REGULATION OF THE PROMOTION OF CONSTRUCTION, SALE, MANAGEMENT AND TRANSFER) ACT, 1972 (Act 16 of 1973). One of the main objectives of this statute was, In the interest of the intending purchasers who advance funds it is necessary to regulate the construction, sale, management and transfer of flats or apartments by individuals or groups of individuals who construct such multi-storeyed buildings.

However, till today (49 years), the state government has neither appointed the proper officer nor regulated this statute, a similar situation prevails in other states also. Hence the central government has stepped in with an intention to regulate and develop the industry, resulting in the enactment of The Real Estate (Regulation & Development) Act 2016 (Act 16 of 2016) which is effective from 1st July 2017.

The Real Estate (Regulation & Development) Act 2016 (affectionately called RERA) empowers the state government to appoint the Authorities to perform their functions within the framework of the statute – with the enactment of RERA, it has become the regulator of the Real Estate Industry.

Important and must-know provisions under RERA. Which may be useful as a professional, individual or home buyer etc –

1. Sale of Real Estate (building) in Carpet Area – Unit of Measurement

2. Deposit of money (minimum 70%) realised from Allottees in a separate designated bank account for the specific Project – Financial Regulation under RERA

Will deliberate on each of these provisions and share the practical experience with the readers of the journal month on month. To start with, the CARPET AREA is the unit of measurement for the transaction in Real Estate projects –

Sl No

Provisions Change in Practice Impact
CARPET AREA – Unit of measurement Prior to RERA, the Real Estate industry followed the practices depending upon market acceptability, ability to convince the stake holders etc.

E.g., Built up Area, Saleable Area, Super Built up Area, loading factor.

There exists an imprecision of measurement of the unit.

The inclusion of definition of Carpet Area under RERA made industry to practice a Common Unit of Measurement in the trade.

While filing the application for grant of RERA Registration for the Real Estate project, the promoter shall submit the Carpet Area Statement of the building, individual units.


The introduction of Carpet Area resulted in –

a) Transparency

b) Standardisation in business and trade practices.

c) Certainty and measurability of Carpet Area.

d) building trust and confidence

e) All marketing collaterals, communication shall mention the Carpet Area of the unit

f) Sale Price / consideration of the unit shall be based on Carpet Area.

g) Any variance in carpet area results in adjustment of consideration.

Sec 2(k) of the RERA Act defines – carpet area” means 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.

Explanation— For the purpose of this clause, the expression “exclusive balcony or verandah area” means the area of the balcony or verandah, as the case may be, which is appurtenant to the net usable floor area of an apartment, meant for the exclusive use of the allottee; and “exclusive open terrace area” means the area of open terrace which is appurtenant to the net usable floor area of an apartment, meant for the exclusive use of the allottee;

Further the requirement of a Promoter of the Real estate project to disclose 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 apartment with the apartment in accordance with Sec 4(2)(h) of the Act, makes it that much more transparent for a home buyer while purchasing an apartment.

Allottees/Customers do understand, appreciate when they have common comparison – lets understand the sensitivity of Carpet Area with a small Example –

Details Project A Project B Other factors
Apartment 2 BHK Unit 2 BHK Unit
Super-built-Up Area 1200 Sft 1200 Sft Both are good, similar location equally good
Total Price 54 Lacs 60 Lacs Generally, everyone tries to compare the price. Lower one would be considered
Carpet Area 800 Sft 900 Sft
Rate per Sft of Carpet Area Rs.6,750 per sft Rs.6,666 per Sft Given the details of Carpet Area, one would prefer Project B, even though the total price is more.

As the price per square feet of carpet area is less and the purchaser gets more area in the apartment.


Excludes External Walls

Excludes Service Areas like utility, balcony, service shafts etc.

Hope you understood the CARPET AREA of the Apartment with this diagram.

The common question is – will the price of the apartment will come down / reduced with implementation of Carpet Area under RERA?

The answer is NO. There will not be any reduction or change in transaction value between the buyer and the builders.

Eg., Apartment with 1200 Square Feet of Super built up Area (900 Square feet of Carpet Area) Costs Rs.60.00 Lacs. Means Rs.5,000/- per square feet of Super built up Area.

Post RERA, the cost of the Apartment continues to be Rs.60.00 Lacs. However, it would mention as (Rs.60.00 Lacs /900 square feet) Rs.6,666/- per square feet of Carpet Area.

Next Question, what will be called for Areas like utility, balcony, veranda, private terraces, service shafts?

RERA Act has a definition of Carpet Area and Common Area. It is assumed that anything other than Carpet Area is called Common Area. Hence, Areas like utility, balcony, service shafts, private terrace (inside the unit) are also fall into the category of Common Area.

However, these are exclusive use for a particular owner of the apartment / unit. Hence, by practice, it will be mentioned as Exclusive common Area. i.e., the owner of the unit will have exclusive right to use of these Areas.

The formula is Built up Area of the Unit = Carpet Area + Exclusive Common Area

However, there exist a common area in the project, i.e., common passage, lobbies, staircase, lift area, parking area, service shaft etc (refer Sec 2(n) of the RERA Act for the Definition of Common Area)

The ownership of the common areas in the real estate project are vests with the Association of Allottees. In turn each allottee gets a right in these Common Areas in proportionate to undivided share in land or based on Carpet Area.

Now the formula of Saleable Area / Super built up Area =

Carpet Area + Exclusive Common Area + Share Areas

Sl No

Area Includes / Defines Measurement in Sq. Feet
1 Carpet Area Net Usable Floor Area + Internal Walls 900
2 Exclusive Common Area Utility, balcony, veranda of the unit for the purpose of Exclusive use of the apartment or unit 100
3 Share Area Sec 2(n) – the staircases, lifts, staircase and lift lobbies, fire escapes, and common entrances and exits of buildings, the common basements, terraces, parks, play areas, open parking areas and common storage spaces; 200

Points to note –

1. RERA Carpet Area = Net Usable Floor Area + Internal Walls (excluding outer walls)

2. Built up Area = RERA Carpet Area + Exclusive common Area

3. Super built-up Area = Built up Area + Share Area

4. Carpet Area statement shall be prepared with the Assistance of Architect as per the provisions of RERA. The statement shall be accurate and error free.

5. It is mandatory to mention the Carpet Area in all documents, marketing collaterals, legal documents, communication with the Allottees, Bankers, lenders etc.

6. Landowners and promoters (builders or developers) shall consider the concept of RERA Carpet Area and accordingly arrive, mention the sharing ratio in Joint Development Agreement.

7. All marketing collaterals like brochures, pamphlets, websites etc shall mention the Carpet Area of the units.

8. Customer Allotment letter, Agreement for Sale, Sale Deed shall have Carpet Area details of the unit / apartment in the project.

9. CA Certificate issued by the practicing Chartered Accountant shall mention the Carpet Area in Annexures under sold and unsold Table.

10. Presently registration of the unit / apartment with sub registrar is based on Super built up Area. Home Buyers, Industry bodies has made a representation to modify the registration of units / apartments based on Carpet Area, which is in line with RERA Act.

a. Government Of Karnataka Department of Stamps and Registration has given a converter to convert the Carpet Area to Super Built-up Area for the purpose of calculation of stamp duty –

11. Haryana RERA issues regulations to sell flats only on carpet area –

a. The Haryana Real Estate Regulatory Authority (HARERA), on April 27, 2021, said that builders can sell apartments in their projects only based on carpet area. While stating that the sale of flats on a super area or any other bench will be treated as fraudulent and an unfair trade practice, the state RERA said penal proceedings would be initiated against builders for violating these instructions.

b. “The property in real estate projects is not properly described by way of mentioning super area without specifically giving details and breakup of the components included in the super area. The practice of sale of the real estate on super area basis is misleading, ambiguous, opaque and gives rise to confusion and complexities and at times results into avoidable litigation,” said Haryana RERA chairman KK Khandelwal.

c. “The practice of sale of real estate on super area basis is misleading, ambiguous, opaque, and gives rise to confusion and complexities, and at times, triggers avoidable litigation,” –

Mr. Khandelwal.

12. Refer to clause 1.7 to the Agreement for Sale as notified by Karnataka, in case of reduction in carpet area compared to agreement for sale, the promoter shall refund amount along with interest. On the other side, Promoter may demand for the increased carpet area only if the increase is more than 3 % compared to agreement for sale – extract of the clause is mentioned here –

a. The Promoter shall confirm to the final carpet area that has been allotted to the Allottee after the construction of the building is complete and the occupancy certificate* is granted by the competent authority, by furnishing details of the changes, if any, in the carpet area. The total price payable for the carpet area shall be recalculated upon confirmation by the Promoter. If there is any reduction in the carpet area then t h e Promoter shall refund the excess money paid by Allottee within sixty days with annual interest at the rate prescribed in the Rules, from the date when such an excess amount was paid by the Allottee.

13. Nonadherence to the provisions of the RERA Act may attract penal provisions. The Authority may issue a Show Cause Notice for levying penalty U/s. 61 of the RERA Act, which may extend up to 5 % of the estimated cost of the Real Estate Project.
