Every year the BMC declares a list of dilapidated buildings in the city, but several of them are not demolished as the residents seek the help of the law to secure a stay order. There is a major issue of illegal structures as well, say BMC officials.

As per the latest list, there are around 442 dilapidated buildings in the city, and the court is hearing the cases of around 150 of them. The Bombay High Court on Thursday asked the BMC and four other civic bodies to submit the status on dilapidated structures in their corporations and the steps they have taken to address the issues, after a building collapsed in Bhiwandi, killing over 30 people.
