Quick answer
Buildings older than 15 years should get a structural audit, and PMC/PCMC regularly issue notices to older buildings before the monsoon. An audit typically costs ₹3–₹10 per sq.ft. and recommends repair or redevelopment.

Key takeaways
- Mandatory for older buildings on notice
- Visual survey plus NDT tests
- Report recommends repair or rebuild
- Key input for redevelopment decisions
01When an audit becomes mandatory
A structural audit becomes mandatory, in practice, once a building crosses roughly 15 years of age, and PMC and PCMC both issue audit notices to societies in older buildings every year ahead of the monsoon, following state government directives that came out of past building collapse incidents. The audit isn't optional once a notice is served — societies that ignore it risk the corporation declaring the structure unsafe and cutting water or power connections, apart from the obvious safety risk to residents.
02What the audit process actually checks
The process starts with a visual survey — a structural engineer walks the building noting cracks, concrete spalling (exposed, corroding rebar), dampness patterns, and any visible deflection in beams or slabs — followed by non-destructive tests where the visual signs warrant deeper investigation: a rebound hammer test gives a quick estimate of surface concrete strength, a carbonation test checks how far the concrete's protective alkalinity has degraded, half-cell potential testing flags embedded rebar corrosion before it becomes visible, and in more serious cases a few small core samples are cut and sent to a lab for actual compressive strength testing. The full exercise typically costs ₹3–₹10 per sq.ft. of built-up area depending on building size and how many NDT tests are needed.
03What the report is used for
The output is a structural rating — essentially categorising the building as needing no action, minor repair, major structural repair, or being unfit for habitation — and this report does double duty: it satisfies the municipal corporation's notice, and it becomes the single most important technical input when a society is weighing repair-and-maintain against full redevelopment, because it puts a real number on how much life the existing structure has left and what retrofitting would cost against rebuilding.

Frequently asked questions
Is a structural audit legally compulsory for my building, or just recommended?
Once your building crosses roughly 15 years of age, PMC and PCMC routinely issue audit notices ahead of the monsoon under state government directives, and once such a notice is served, the audit is no longer optional — ignoring it risks the corporation declaring the structure unsafe and disconnecting utilities.
What's the difference between the visual survey and the NDT tests mentioned in an audit?
The visual survey is the engineer walking the building noting visible cracks, concrete spalling, dampness, and deflection; non-destructive tests (NDT) go deeper only where the visual signs warrant it — rebound hammer for surface concrete strength, carbonation testing, half-cell potential for hidden rebar corrosion, and occasionally core-cutting for lab-tested compressive strength. Not every audit needs every NDT test; the engineer selects based on what the visual survey flags.
If my building's structural audit comes back "needs major repair," does that mean we must redevelop?
Not necessarily — "major structural repair" and "unfit for habitation" are different ratings, and the audit report's job is to give the society a real cost comparison between retrofitting the existing structure versus rebuilding, which then feeds into the society's financial decision rather than dictating it outright.
