The 182 winners of Maharashtra Housing and Area Development Authority’s (MHADA) lottery in 2015 will have to pay Rs 2 lakh extra for MHADA’s laxity. In 2015, MHADA conducted lottery for 997 homes in Pratiksha Nagar, Mankhurd, and Gavanpada in Mulund and Unnatnagar in Goregaon. Of these, 182 homes were for low income group in Gavanpada. However, as these buildings did not have an occupation certificate (OC) from BMC, the lottery winners were not issued allotment letters. The MHADA has now secured OC for these building. The housing authority proposes to increase flat prices, said a senior MHADA official who did not want to be named.
