Carpet Area Rules Under RERA: Why Buyers Pay for Less Space
Clear Definition Ends Super Built-Up Confusion
Pricing Transparency & Buyer Rights Strengthened
By Vishwas Kumar
New Delhi: May 30, 2026:
Before the Real Estate (Regulation and Development) Act, 2016 (RERA), builders often sold flats based on super built-up area, which included common spaces like lobbies, lifts, and clubhouses. Buyers ended up paying for space they couldn’t use. RERA changed this by mandating that flats must be sold based on carpet area, ensuring transparency and fairness.
Key Legal Provisions
- Carpet Area Definition (RERA Section 2(k)):
- Net usable floor area of an apartment.
- Includes area covered by internal walls.
- Excludes balconies, verandahs, terraces, and external walls.
- Super Built-Up Area Ban:
- Builders cannot sell flats based on super built-up area.
- Pricing must be linked to carpet area only.
- Transparency in Agreements:
- Builder-buyer agreements must clearly mention carpet area.
- Any variation beyond 5% entitles buyers to refund or compensation.
- Impact on Pricing:
- Flats appear smaller when measured by carpet area.
- Buyers pay only for usable space, not inflated super built-up figures.
Impact on Buyers & Builders
- Buyers:
- Greater clarity on actual usable space.
- Protection against misleading advertisements.
- Legal remedy if carpet area differs from agreement.
- Builders:
- Must disclose carpet area upfront.
- Cannot inflate prices using super built-up calculations.
- Increased accountability under RERA authorities.
