⚡ Quick Answer
Carpet area is the actual usable floor space inside an apartment. Built-up area includes carpet area plus wall thickness (~10–15% extra). Super built-up area includes common areas like lobby, lift, staircase shared proportionally (~25–30% extra). Under RERA, all transactions must be based on carpet area.
Area Definitions with Example
| Area Type | What's Included | Typical Addition | Example (2 BHK) |
|---|---|---|---|
| Carpet Area | Usable rooms + bathrooms + balcony (RERA definition) | Base | 650 sqft |
| Built-Up Area | Carpet area + wall thickness + duct shafts | ~10–15% extra | 720–750 sqft |
| Super Built-Up Area | Built-up + proportional share of lobby, lift, staircase, gym, etc. | ~25–35% extra | 850–950 sqft |
Key RERA Rule
Post-RERA (2016), all property sales MUST quote price on carpet area. Always ask the developer for RERA carpet area, not super built-up area, when comparing flats.
