Is Balcony Included in Carpet Area as per RERA?

One of the most common points of confusion for homebuyers in India is the treatment of balconies when calculating the carpet area of an apartment. For decades, property advertisements and sale brochures quoted different types of area—carpet, built-up, and super built-up—often leaving buyers uncertain about what space they were actually paying for. 

The enactment of the Real Estate (Regulation and Development) Act, 2016 (RERA) has brought about greater standardisation and transparency, especially in the way carpet area is defined and calculated. But even today, many buyers ask: Is the balcony included in the carpet area as per RERA?

What is Carpet Area Under RERA?

Before answering whether the balcony is included, it is important to understand what exactly constitutes “carpet area” under RERA.

Section 2(k) of the RERA Act, 2016 clearly 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 includes the area covered by the internal partition walls of the apartment.”

In simple terms, the RERA carpet area is the actual usable area inside the apartment, measured from the inner faces of the walls, and including the space occupied by internal partition walls. It does not include the thickness of external walls, service shafts, balconies, verandahs, or open terraces.

Balconies as per RERA: Excluded from Carpet Area

The wording of the RERA Act is unambiguous—balconies are excluded from the definition of carpet area. The Act specifies “exclusive balcony or verandah area and exclusive open terrace area” as exclusions.

• Even if the balcony is attached to a specific flat and is for your personal use, it does not form part of the carpet area under RERA.
• The law applies uniformly, irrespective of whether the balcony is covered, open, or enclosed with grills or glass.

Practical Implication

• When a builder or developer quotes the RERA carpet area for an apartment, that figure refers only to the net usable floor area inside the flat (plus internal walls), not the balcony.
• The area of balconies, verandahs, and open terraces must be listed separately in the sale agreement, brochure, and marketing materials.

Why Are Balconies Excluded from Carpet Area?

Preventing Inflation of Usable Space

Balconies are essentially semi-open or outdoor spaces, designed for leisure, fresh air, or utility purposes. Including them in the carpet area would artificially increase the “usable” area shown on paper, even though this space is not truly part of the interior living area.

Ensuring Transparency

RERA’s main objective is to make property transactions fair and transparent. By clearly excluding balconies from carpet area calculations, RERA ensures that buyers pay only for the real, usable indoor space and are not misled by inflated numbers.

Standardisation Across India

Earlier, different states and developers used their own definitions for carpet area, sometimes including balconies and sometimes not. RERA standardises this across the country, so buyers can compare properties on an even platform.

How Is Balcony Area Treated in RERA-Compliant Documents?

Separate Disclosure Is Mandatory

Under RERA, the builder must provide three distinct area figures for every flat:

1. RERA Carpet Area: Usable indoor area plus internal partition walls (no balcony/terrace).
2. Exclusive Balcony/Verandah Area: Total area of all balconies and verandahs attached to the flat, mentioned separately.
3. Exclusive Open Terrace Area: If there is an open terrace for exclusive use, its area is listed separately.

The sale agreement, allotment letter, and all marketing brochures must clearly distinguish between these areas.

Pricing Only on Carpet Area

The per square foot rate advertised and agreed upon in the sale agreement must be applied only to the RERA carpet area—not the sum of carpet area and balcony area. The area of balconies, verandahs, or open terraces can be priced separately if the developer so desires, but must not be combined with the carpet area for main pricing.

Example: Calculating Carpet Area and Balcony Area

Let’s say you are considering a 2BHK flat with the following layout:

• Living Room: 16 x 12 ft
• Bedroom 1: 12 x 10 ft
• Bedroom 2: 10 x 10 ft
• Kitchen: 8 x 10 ft
• Bathrooms: 5 x 7 ft (2 bathrooms)
• Internal Partition Walls: Total area of 32 sq ft
• Balcony 1: 5 x 10 ft (50 sq ft)
• Balcony 2: 4 x 8 ft (32 sq ft)

Calculation:

• Carpet area (rooms): (16×12) + (12×10) + (10×10) + (8×10) + (5×7×2)
  = 192 + 120 + 100 + 80 + 70 = 562 sq ft
• Add internal partition walls: 562 + 32 = 594 sq ft (RERA carpet area)
• Total balcony area: 50 + 32 = 82 sq ft

In all RERA-compliant documents, your flat would be described as:

• RERA Carpet Area: 594 sq ft
• Exclusive Balcony Area: 82 sq ft

Common Misconceptions

Enclosed Balconies

Some buyers may believe that if a balcony is enclosed (with windows, grills, or glass), it will be counted as part of the carpet area. Under RERA, this is not the case. Unless the space is fully merged into a room as per the approved building plan, it remains a balcony and is excluded from the carpet area.

Super Built-Up Area and Saleable Area

Earlier, many developers quoted the “super built-up” or “saleable” area, which included balconies, verandahs, open terraces, and a proportionate share of common areas like lobbies, lifts, and clubhouses. RERA has made it mandatory to use only the carpet area for pricing, to protect buyers from inflated area figures.

Quoting a Single Figure

If a builder quotes a single figure that includes both carpet area and balcony, this is not compliant with RERA. Always insist on seeing separate figures for carpet area and balcony area in all documents.

What Should Buyers Check Before Signing?

1. Sale Agreement: Ensure the RERA carpet area and balcony area are listed separately.
2. RERA Registration: Only buy from RERA-registered projects; check details on your state RERA portal.
3. Approved Floor Plan: Compare the floor plan approved by the local authority with what is shown by the builder.
4. Legal Advice: When in doubt, consult a lawyer or technical expert before making a payment.

Conclusion

As per RERA, the balcony is not included in the carpet area. Only the net usable indoor space plus internal partition walls make up the RERA carpet area. Balconies, verandahs, and open terraces are always excluded and must be disclosed separately in all agreements and documents. This legal clarity protects homebuyers, ensures fair pricing, and brings much-needed transparency to the Indian real estate market.
