Structural Audit Outcomes and What They Mean
| Outcome | Meaning | Action Required | Buyer Implication |
|---|---|---|---|
| Fit for Occupation | Building is structurally sound — minor maintenance only | Routine maintenance per recommendations | No concern — safe to buy |
| Structurally Repairable (C1/C2) | Issues found — requires specific repairs to remain safe | Execute repairs within specified timeline; re-audit after | Caution — check sinking fund; repairs = additional cost |
| Unsafe / Unfit (C3) | Structurally dangerous — building cannot be occupied safely | Vacate immediately; demolish or undertake major reconstruction | Do not buy — serious legal and safety risk |
Structural Audit Checks for Buyers of Old Buildings
What to Check When Buying an Older Property
- Has audit been done? For buildings 15–30+ years old, ask society secretary for structural audit report
- What was the outcome? Request copy of audit report and recommendations letter
- Have repairs been done? If C1/C2 outcome — verify recommended repairs were executed by checking society records
- Sinking fund sufficiency: Does the society have adequate sinking fund for upcoming major repairs?
- Is audit overdue? If no audit done for a 30+ year building, this is a red flag — society is non-compliant
- Redevelopment potential: Repeated structural issues often lead to redevelopment — understand your rights as a flat owner

Frequently Asked Questions
Structural audit is a technical assessment of a building's structural safety — examining foundations, columns, beams, slabs, and load-bearing capacity. Licensed structural engineers check for cracks, spalling concrete, corroded reinforcement, and settlement. Outcomes: Fit (safe), Repairable (repairs needed), or Unsafe (vacate/demolish). Mandatory for buildings over 15–30 years depending on city.
Mandatory age varies by city: Mumbai — buildings 30 years and above; Delhi — 15 years and above; other cities have their own thresholds per local bylaws. Society is responsible for arranging audits. Penalties apply for non-compliance. Many older buildings have not done audits — buyers should specifically ask about audit status for buildings over 20 years old.
C1 (minor issues) and C2 (moderate issues) classifications require specific repairs within a timeline — re-audit follows to verify. C3 (unsafe) classification requires immediate vacation of the building. The municipal authority may issue vacation/demolition notices. Residents can seek redevelopment — either through the Co-operative Societies route or under state government redevelopment schemes. Banks may not provide loans against C3-classified buildings.
Yes — absolutely. For any building over 20 years old, ask the society secretary for the most recent structural audit report. Check if it has been done, what the outcome was, and whether recommended repairs have been executed. An absent or overdue structural audit on an aging building is a significant red flag. Factor potential repair costs (funded by sinking fund levies) into your purchase decision.
Banks are increasingly cautious about older buildings. A building with a C2 (needs repairs) classification may still get loans if repairs are underway. A building with C3 (unsafe) classification will typically not get home loans — banks will not lend on property that is officially classified as unsafe for occupation. Check the structural audit status of any older building before applying for a loan.
