The 2026 Legal Landscape for Housing Societies

In Mumbai, building safety is no longer just a recommendation—it is a strict legal mandate enforced by the MCGM. Under Section 353B of the MMC Act, every building owner or housing society committee is legally responsible for the structural stability of their premises. As of 2026, the BMC has started issuing automated notices to buildings that have crossed the 30-year mark without a fresh Stability Certificate on record.

Mandatory Audit Timelines:

• 15 to 30 Years: Structural Audit required every 5 years.
• 30+ Years: Structural Audit required every 3 years.

The Step-by-Step Compliance Process:

1. The Appointment: The society must appoint a BMC-registered Structural Engineer to conduct a visual and technical inspection.
2. NDT Testing: Urban Civil Services assists engineers by performing Non-Destructive Tests (like Rebound Hammer and USPV) to check the internal health of the concrete.
3. The Audit Report: The engineer categorizes the building into C-1 (Dangerous), C-2A (Major Repairs), C-2B (Minor Repairs), or C-3 (Safe).
4. Execution: If categorized as C-2A or C-2B, the society must complete the repairs within the stipulated time mentioned in the notice to avoid legal action or water disconnection.

Failure to comply with Section 353B is a punishable offense. More importantly, it puts the lives of residents at risk during the turbulent Mumbai monsoons.

The Proforma 'B' and Form 6 Submission Process

A structural audit is only legally 'complete' when your MCGM-registered auditor submits Proforma B to the Ward Office. This document confirms the structural health category (C1, C2-A, C2-B, or C3). If your building is marked C2, you are given a specific timeframe to complete repairs. Failing to submit this can result in the disconnection of water and electricity supply under Section 354 of the MMC Act.

Key Action: Ensure your auditor is on the 'Registered Structural Engineers' list of the BMC for the year 2026.
