Carpet Area vs Built-Up Area in Mumbai: What Buyers Should Know
UrbanKeyHome | Mumbai homebuyer guide
What is carpet area?
In general, carpet area refers to the net usable floor area within the apartment, excluding external wall areas and other exclusions defined by the applicable law. RERA has a specific definition; refer to the agreement and official guidance for the exact treatment of balconies and other areas.
What is built-up area?
Built-up area commonly includes the apartment’s carpet area plus wall thickness and certain attached areas. The way it is presented can vary, so ask for a written breakdown rather than relying on the label alone.
What do people mean by saleable or super built-up area?
These terms may include a share of common areas in addition to the apartment. Definitions and practices can vary. Do not compare a quoted saleable-area rate with a carpet-area rate as if they were the same measurement.
How to compare two flats
Ask each seller or builder for the carpet area in writing, a dimensioned floor plan, the total price and a full cost sheet. Compare price per carpet-area unit only when the area definitions and included costs are consistent.
What to confirm before booking
Check that the agreement’s area details match the relevant approved documents and project disclosures. Ask questions about balconies, terraces, ducts and other spaces. If a measurement or clause is unclear, have a qualified professional explain it before you sign.
