The Brihanmumbai Municipal Corporation will conduct a three-month drive against unauthorised slum structures measuring 14 feet or more from October 1 to December 31, 2026, putting thousands of constructions across the city and suburbs under enforcement scrutiny.
The civic body said the drive is being carried out under the directions of BMC Commissioner Ashwini Bhide, with guidance from Additional Municipal Commissioner (City) Prajakta Verma-Lavangare and leadership from Joint Commissioner (Vigilance) Devender Singh. The BMC has appealed to residents living in unauthorised constructions to remove them voluntarily and immediately, warning that strict action will follow in cases of non-compliance.
According to figures cited by the BMC, Brihanmumbai has 223,150 slum structures across Mumbai city and the suburban areas. Of these, 39,111 structures have been identified as measuring 14 feet or more in height. The figure includes 3,348 structures in the city area, 4,536 in the western suburbs and 31,227 in the eastern suburbs.
The eastern suburbs account for the largest share of the identified structures, representing nearly four-fifths of the total. The distribution places the bulk of the planned enforcement activity in suburban wards, where dense informal settlements and incremental construction have expanded alongside the city’s formal housing and infrastructure networks.
The BMC said eviction action has already been taken against 4,584 of the identified structures, while notices have been issued to another 611. Residents occupying the remaining structures have been asked to dismantle the unauthorised additions themselves. The civic body has not provided, in the reported announcement, a ward-wise schedule or details of rehabilitation arrangements linked to the drive.
The announcement follows continuing action by BMC administrative wards against unauthorised construction across Brihanmumbai. Between August 24 and September 15, civic authorities took eviction action against 128 unauthorised constructions, while action against a further 140 constructions was planned, according to the civic body.
The enforcement drive comes as the BMC is also focusing on conditions in Mumbai’s slum and densely populated areas. The civic body had earlier approved in principle a technology-driven cleanliness scheme for such localities, including GPS-based monitoring and a QR-based complaint system intended to improve oversight of sanitation services.
The BMC has urged citizens not to undertake unauthorised construction and asked those who have already built such structures to remove them immediately. The three-month drive is scheduled to begin on October 1 and continue through December 31, 2026.
