Thousands of residents could be living in structurally unsafe buildings this monsoon, as the Navi Mumbai Municipal Corporation (NMMC) steps up enforcement against ageing structures that have not undergone mandatory audits.

In one of its strongest pre-monsoon drives yet, the civic body has begun ward-wise surveys to identify dangerous buildings. Officials said structures found unsafe will be classified under Section 264 of the Maharashtra Municipal Corporation Act, with those in the highest-risk C-1 category facing immediate evacuation in line with High Court directives.
