The checks behind the lobby: occupancy certificate coverage, fire NOC, sanctioned-vs-built deviation, landlord title and mortgages, and N+1 systems, before you lease in Chennai.
The occupancy certificate is the building's licence to be occupied; verify it exists, covers the floors you are taking, and matches your intended use, an OC for IT use does not automatically cover a clinic or a kitchen-heavy facility. The fire NOC must be current, not historic, and renewals must match the building's present configuration. Lifts carry their own licences; DG sets and HT power connections carry CEIG and TANGEDCO approvals worth sighting.
Sanctioned-versus-built deviation is the quiet risk: floors or mezzanines beyond the sanctioned plan can face regularisation demands or, in the hard cases, sealing, with the tenant collaterally damaged.
Verify the landlord's title chain and whether the asset is mortgaged; a building under a lender's charge means your lease should carry a non-disturbance arrangement, or at minimum you should know the enforcement risk. On SEZ land or leasehold structures, confirm the head lease permits subletting to you for your full term, and check for litigation on the land or between co-owners, a frequent feature of inherited commercial plots.
None of this requires the landlord's cooperation to check: EC, deeds and case records answer most of it, which is exactly what our 30-point building verification reads.
For an occupier whose business is uptime, the engineering documents matter more than the lobby finish. Power: dual feed or single, DG capacity per sq.ft against your load, switchover time. Cooling: chiller redundancy, chilled-water hours versus your shift pattern, and who pays for extension. Vertical transport: lift count and capacity against floor population at peak. Floor loading for dense storage, labs or equipment. Verify each against documents and test certificates, not assurances.
Where the building falls short, the lease can sometimes fix it, dedicated DG, extended chilled-water hours, but only if the gap is identified before signing.
Run the checks in cost order: title, OC and fire first, because a failure there kills the option cheaply; systems and deviation checks next on the surviving shortlist; and a physical audit, including a monsoon-season look at basements and access roads, before the term sheet locks. The whole sequence runs in parallel with commercial negotiation and typically costs days, not weeks.
Occupiers who skip this discover it during an incident, an insurance claim, or a regulatory inspection, the three most expensive classrooms in real estate.
There is no statutory definition. In practice: institutional ownership, current OC and fire compliance, N+1 power and cooling, adequate lifts and parking, and professional management. Each element is verifiable; the label itself is marketing.
OC coverage for your floors and use, fire NOC currency, sanctioned-versus-built deviations, the landlord's title and mortgages, power and cooling redundancy against your load, and litigation on the asset.
Yes. A lender enforcing its charge can disturb occupancy. Check the EC for charges and negotiate non-disturbance protection where the asset is leveraged.
