Understanding RERA Carpet Area: A Guide to Property Measurements
july 07, 2025
Buying a home is a huge milestone – and often one of the biggest financial commitments you'll ever make. Yet, when it comes to choosing the right property, many buyers find themselves confused by all the technical terms floating around, especially those related to space and pricing. How much space are you truly getting? Are you being charged fairly?
That’s where understanding RERA (Real Estate Regulatory Authority) carpet area becomes crucial. In this article, we’ll understand what RERA carpet area means, how it is calculated, and why it’s essential for making informed, confident decisions when purchasing a home.
What Is RERA Carpet Area?
Before the Real Estate (Regulation and Development) Act (RERA) came into force in 2016, property area terms varied widely, often leaving buyers misinformed or misled.
Under RERA, carpet area has a clear and standard definition. It refers to the net usable floor area within your apartment walls – essentially, the space where you can actually live in, walk around, and place your furniture.
This standardisation helps ensure you know exactly what you’re paying for, with no misleading numbers or undefined measurements.
Why RERA Carpet Area Matters to You
When you’re investing your money in a property, every square foot counts. Understanding the carpet area as per RERA helps you:
- Compare properties more accurately based on usable space.
- Avoid overpaying for areas you won’t use.
- Understand the price breakdown with greater transparency.
- Make smarter purchase decisions by focusing on the liveable area.
Essentially, it brings more transparency and fairness into what was once a confusing process for buyers.
RERA Guidelines for Carpet Area
RERA has made it mandatory for builders to mention the carpet area in all agreements and marketing materials. So when reviewing brochures or floor plans, always look for the carpet area, not just the built-up or super built-up area.
If there's a change in the carpet area during construction, developers must inform the buyer and adjust the cost accordingly. This level of accountability protects your investment and builds trust.
What’s Included in RERA Carpet Area and What’s Not?
To understand your home's space, it helps to know exactly what goes into the carpet area calculation as per RERA.
| What’s Included |
What’s Excluded |
| Living & dining areas |
External walls |
| Bedrooms |
Service shafts |
| Bathrooms & kitchen |
Balconies & verandahs |
| Internal walls |
Open terraces |
How Is RERA Carpet Area Calculated?
Let’s break this down with an example. Suppose you’re considering an apartment with a total built-up area of approximately 1,350 sq. ft. The non-usable parts might be:
- External walls: Approx 160 sq. ft.
- Balcony: Approx 60 sq. ft.
- Service shafts: Approx 40 sq. ft.
Your carpet area would be:
1,350 - (160 + 60 + 40) = 1,090 sq. ft.
This 1,090 sq. ft. is the space you’ll actually live in – your real, usable home.
Common Misconceptions About Carpet Area
Many buyers still confuse carpet area with other measurements. Here’s how they differ:
- Built-up Area: Carpet area plus wall thickness and balcony space.
- Super Built-up Area: Built-up area plus a share of common areas like lifts, staircases, and corridors.
