A four-storey building in Bhiwandi, Thane collapsed on July 30, killing ten people and injuring three. The Kohinoor Building was incorrectly classified by a local ward officer, according to top civic sources, which delayed necessary safety measures. This error allowed residents to stay in the building while repairs were carried out without civic permission. The building, with 48 rooms, was listed under Category "C2B" despite being one of the most dangerous structures that should have required immediate evacuation. A contractor began repair work without obtaining authorization from the Bhiwandi Nizampur City Municipal Corporation (BNCMC). Local staff also provided incorrect information to higher authorities, concealing the building's true structural condition and delaying stronger action. The civic commissioner has taken leave, and Thane Collector Shrikrishna Panchal has ordered comprehensive re-audits and fresh classification of all structures under C-1, C2A, and C2B categories across Bhiwandi. Disciplinary action and accountability will be fixed on civic officials found to have submitted false or negligent building classifications. The BNCMC stated that the building had been identified as "dangerous" since September 2020, but property owners illegally began structural repair work before eviction notices were issued in June 2026. Police have registered an FIR under the Bharatiya Nyaya Sanhita against the building owner and a contractor allegedly carrying out unauthorized work at the premises. The incident has brought focus on the classification of dangerous structures, the action taken by civic officials, and the repair work that was reportedly carried out without authorization.
