Carpet Area vs. Built-up Area: A RERA Perspective

The Shift in Selling Practices

Before RERA, calculating a property's size was ambiguous. Developers often included balconies, corridors, and sometimes common spaces in the area sold to the buyer (Super Built-Up Area).

The RERA Definition:

Under RERA, properties must be sold strictly based on the Carpet Area. This is defined as the net usable floor area of an apartment, excluding the area covered by external walls, areas under services shafts, exclusive balconies or verandahs, and exclusive open terrace areas, but includes the area covered by the internal partition walls of the apartment.

This ensures you only pay for the area you actually use inside your home.
