Mumbai Building Safety Laws 2026: A Deep Dive into Section 353B and 354
The Legal Pillars of Mumbai's Skyline
Building safety in Mumbai is governed by two heavyweight sections of the Mumbai Municipal Corporation (MMC) Act of 1888. In 2026, the enforcement of these laws has become stricter than ever to prevent monsoon-related collapses.
1. Section 353B: The Audit Mandate
This section makes it obligatory for owners and occupants of buildings older than 30 years to conduct a structural audit.
- Liability: The Chairman and Secretary of the society can be held personally liable (criminally and civilly) for negligence if an audit is not conducted.
- Fines: Failure to comply can result in fines and the revocation of the Occupancy Certificate (OC).
2. Section 354: The 'Dangerous Structure' Notice
If a building is deemed 'ruinous' or 'likely to fall,' the Commissioner issues a notice under Section 354.
- Evacuation: If the building is C1, the BMC has the power to forcibly vacate and demolish it.
- Protection: This law also empowers the BMC to install 'propping' or fencing at the owner's expense if they fail to secure the structure.
3. New 2026 Directives
Recent High Court rulings have emphasized that the Technical Advisory Committee (TAC) is the final authority in disputes regarding a building's category. If there are conflicting reports between a private auditor and the BMC's auditor, the TAC's decision is binding.
