Understanding C2-B Classification: 'Repair Without Vacation' for Mumbai Societies
The 'Safe Zone' of Structural Repairs
When the BMC classifies a building as C2-B, it means: "Structural repairs are required, but residents do not need to vacate the premises." This is the most critical stage for a Housing Society. If you act now, you save the building. If you wait 24 months, the building will likely degrade to C1 (Dangerous/Demolish).
What counts as a C2-B Repair?
- Localized Column Jacketing: Strengthening specific columns that show signs of distress.
- Slab Patch Work: Repairing spalled concrete in individual flats or common passages using Polymer Modified Mortar (PMM).
- External Plastering: Replacing hollow or cracked plaster to stop water ingress into the RCC.
- Waterproofing: Solving terrace or toilet leakages that are the root cause of the structural damage.
The Timeline of a C2-B Notice:
Once the audit is submitted, the BMC typically issues a notice under Section 354 or Section 353B, giving the society 3 to 6 months to complete the repairs.
- Work Order: The society appoints a contractor like Urban Civil Services.
- Execution: Repairs are carried out with external scaffolding.
- Completion: The auditor issues a 'Repair Completion Certificate' and a fresh 'Stability Certificate.'
- De-listing: The BMC removes the building from the 'Dilapidated' list in their records.
