MahaRERA — What Mumbai Buyers Must Know
Maharashtra has one of India's most active RERA authorities. All residential projects above 500 sq meters must be MahaRERA registered. Verify at maharerait.maharashtra.gov.in. Maharashtra RERA number format: P51800XXXXXX
MahaRERA advantage: Maharashtra RERA is one of the few states where you can see the builder's bank account for the project — funds must be deposited as per RERA rules. This is a strong buyer protection that many states don't have.
Mumbai-Specific Red Flags
- Redevelopment projects — verify existing tenants have vacated and NOC obtained
- SRA (Slum Rehabilitation Authority) projects — check SRA approval and rehab component clearly
- Projects on reclaimed land in Navi Mumbai — verify environmental clearances
- High-rise above 70 floors — check fire NOC and structural engineer certification
5 Things to Check Before Buying in Mumbai
- ✅ MahaRERA registration at maharerait.maharashtra.gov.in
- ✅ Builder's consumer forum cases in Mumbai district forum
- ✅ Price vs micro-market benchmark — don't compare Thane to Andheri
- ✅ Carpet area vs super built-up area — Mumbai builders load heavy
- ✅ OC (Occupancy Certificate) for ready-to-move units
