With Diwali festivities over, the East Delhi Municipal Corporation (EDMC) is likely to start a month-long sealing drive from November 21 to crack down on properties that have not paid conversion charges.
The drive was supposed to be conducted before Diwali but was postponed due to the lack of police support.
Officials said that they had written to the police for assistance and had given details of each of the 15,000 premises that would be sealed.
"Earlier, the police could not give us forces because they were busy with Diwali security but we requested them to make arrangements after the festivities," said an official.
The corporation's officials said the crackdown would be carried out simultaneously in both the administrative zones — north and south Shahadra. One road in both zones will be targeted each day.
The earlier list contained details of 18,000 properties. But in the last few weeks, 3,000 property owners had paid convergence charges and were put off the sealing list.
The conversion fees are charged when a residential property is put to commercial or mixed land use.
Of the total properties to be sealed, over 12,000 fall in Shahadra (south) zone, while around 3,000 properties are in Shahadra (north).
Under the Shahadra (south) zone, the maximum defaulters are in Anarkali, followed by Shakarpur, Geeta Colony, Patparganj and Vishwas Nagar areas.
Under the Shahadra (north) zone, most defaulters are in Nand Nagri, Old Seemapuri, Ashok Nagar and New Seemapuri areas, corporation officials said.
The North Corporation has also sent notices to 5,000 properties for non-payment of taxes but is yet to fix a date for the sealing.
The municipal body plans to print the names of the highest defaulters in the newspapers in a bid to shame them into paying the money.
